Description
本发明要求2022年11月18日递交的发明名称为“数据传输方法与装置、终端设备和网络设备”的申请号202211446407.8的在先申请优先权，上述在先申请的内容以引入的方式并入本文本中。The present invention claims priority of the prior application No. 202211446407.8 filed on November 18, 2022, with the invention name “Data Transmission Method and Apparatus, Terminal Equipment and Network Equipment”. The contents of the above-mentioned prior application are incorporated into this text by introduction.
本申请涉及通信技术领域，尤其涉及一种数据传输方法与装置、终端设备和网络设备。The present application relates to the field of communication technology, and in particular to a data transmission method and apparatus, a terminal device, and a network device.
目前，第三代合作伙伴计划组织(3rd Generation Partnership Project，3GPP)所规范的标准协议针对业务的数据特性讨论了终端设备在应用层上何时向用户呈现该业务的数据，以便实现该业务的数据呈现特性。Currently, the standard protocol specified by the 3rd Generation Partnership Project (3GPP) discusses when the terminal device presents the data of the service to the user at the application layer based on the data characteristics of the service, so as to realize the data presentation characteristics of the service.
例如，以用户使用终端设备听音乐的场景为例，在该场景下的业务的数据为音频数据，而为了实现音乐在用户的左耳和右耳之间进行先后环绕的听觉效果，终端设备需要在应用层上将左耳的音频数据与右耳的音频数据在时间上按照先后顺序进行呈现。如果左耳的的音频数据先呈现，而右耳的音频数据后呈现，用户将感受到左耳先听到一段音乐，右耳后听到下一段音乐，如此循环。For example, in the scenario where a user uses a terminal device to listen to music, the service data in this scenario is audio data. In order to achieve the auditory effect of music being surrounded by the user's left ear and right ear, the terminal device needs to present the audio data of the left ear and the audio data of the right ear in a time sequence at the application layer. If the audio data of the left ear is presented first and the audio data of the right ear is presented later, the user will feel that the left ear hears a piece of music first, and the right ear hears the next piece of music later, and so on.
又例如，以多个用户分别使用终端设备玩游戏的场景为例，在该场景下的业务的数据为游戏画面，而为了实现将游戏画面在不同用户上先后呈现以产生更加逼真的视觉效果，不同终端设备在应用上向各自的用户呈现游戏画面时会按照先后的时间顺序。For another example, take a scenario in which multiple users use terminal devices to play games respectively. The business data in this scenario is the game screen. In order to present the game screen to different users in sequence to produce a more realistic visual effect, different terminal devices will present the game screen to their respective users in the application in chronological order.
虽然目前在业务的数据特性上讨论了业务的数据呈现特性，但是业务的数据呈现特性在用户的业务需求层面上显得相对单一，无法满足各类用户的业务使用需求等，因此如何对业务的数据特性进行增强，以便满足用户使用该业务的不同需求，还需要进一步研究。Although the data presentation characteristics of the business have been discussed in terms of the data characteristics of the business, the data presentation characteristics of the business are relatively simple in terms of the business needs of users and cannot meet the business usage needs of various users. Therefore, further research is needed on how to enhance the data characteristics of the business to meet the different needs of users for using the business.

在一些可能的实现中，网络设备可以是一个独立的节点以实现上述基站的功能或者，网络设备可以包括两个或多个独立的节点以实现上述基站的功能。例如，网络设备包括集中式单元(centralized unit，CU)和分布式单元(distributed unit，DU)，如gNB-CU和gNB-DU。进一步的，在本申请的另一些实施例中，网络设备还可以包括有源天线单元(active antenna unit，AAU)。其中，CU实现网络设备的一部分功能，DU实现网络设备的另一部分功能。比如，CU负责处理非实时协议和服务，实现无线资源控制(radio resource control，RRC)层、服务数据适配(service data adaptation protocol，SDAP)层、分组数据汇聚(packet data convergence protocol，PDCP)层的功能。DU负责处理物理层协议和实时服务，实现无线链路控制(radio link control，RLC)层、媒体接入控制(medium access control，MAC)层和物理(physical，PHY)层的功能。另外，AAU可以实现部分物理层处理功能、射频处理及有源天线的相关功能。由于RRC层的信息最终会变成PHY层的信息，或者由PHY层的信息转变而来，因此，在该网络部署下，高层信令(如RRC信令)可以认为是由CU生成，由DU发送的，或者由DU和AAU共同发送的。可以理解的是，网络设备可以包括CU、DU、AAU中的至少一个。另外，可以将CU划分为RAN中的网络设备，或者，也可以将CU划分为核心网中的设备，对此不做具体限定。In some possible implementations, the network device may be an independent node to implement the functions of the above-mentioned base station, or the network device may include two or more independent nodes to implement the functions of the above-mentioned base station.

In addition, the AAU can implement some physical layer processing functions, RF processing and related functions of active antennas. Since the information of the RRC layer will eventually become the information of the PHY layer, or be converted from the information of the PHY layer, under this network deployment, high-level signaling (such as RRC signaling) can be considered to be generated by the CU, sent by the DU, or sent jointly by the DU and the AAU. It can be understood that the network device may include at least one of the CU, DU, and AAU.

二、业务的数据特征的增强2. Enhancement of business data features
1、描述1. Description
虽然目前在业务的数据特性上讨论了业务的数据呈现特性，但是业务的数据呈现特性在用户的业务需求层面上显得相对单一，无法满足各类用户的业务使用需求等。Although the data presentation characteristics of the business have been discussed in terms of the data characteristics of the business, the data presentation characteristics of the business appear to be relatively simple in terms of the business needs of users and cannot meet the business usage needs of various users.
基于此，本申请实施例引入业务的数据递交特性，通过数据递交特性来描述终端设备在接收到业务的数据之后向上层递交该业务的数据的相关特性，从而实现业务的数据特性的增强，增强业务的数据传输，丰富用户使用该业务的场景，以及满足用户更多的业务使用需求。
Based on this, the embodiment of the present application introduces the data delivery characteristics of the service, and uses the data delivery characteristics to describe the relevant characteristics of the terminal device submitting the data of the service to the upper layer after receiving the data of the service, so as to enhance the data characteristics of the service, enhance the data transmission of the service, enrich the scenarios in which users use the service, and meet more service usage needs of users.
2、具体说明2. Specific instructions
下面对本申请实施例所涉及的技术方案、有益效果、概念等进行具体说明。The technical solutions, beneficial effects, concepts, etc. involved in the embodiments of the present application are described in detail below.
1)业务的类型1) Type of business
需要说明的是，本申请实施例的业务可以具有不同类型。因此，业务的数据，可以是同一类型的业务的数据，可以是多种类型的业务的数据，对此不作具体限制。It should be noted that the services in the embodiments of the present application may be of different types. Therefore, the service data may be data of services of the same type or data of services of multiple types, and there is no specific limitation on this.
具体的，业务的类型包括时延敏感(latency sensitive)业务、流分类服务(stream classification service，SCS)业务、实时应用程序(real-time application，RTA)业务、低时延(low latency)业务、时延敏感且数据量大的业务、低时延高可靠性的业务、低时延高可靠且数据量大的业务、数据量大的业务等。Specifically, the types of services include latency sensitive service, stream classification service (SCS) service, real-time application (RTA) service, low latency service, latency sensitive and large data volume service, low latency and high reliability service, low latency and high reliability and large data volume service, large data volume service, etc.
例如，业务的类型可以包括扩展现实(Extended Reality，XR)业务、虚拟现实(Virtual Reality，VR)、增强现实(Augmented Reality，AR)、混合现实(Mixed Reality，MR)、在线视频业务、在线直播业务、在线语音业务等。For example, the types of services may include extended reality (XR) services, virtual reality (VR), augmented reality (AR), mixed reality (MR), online video services, online live broadcast services, online voice services, etc.
需要说明的是，XR业务以视频业务为主，该视频业务的数据呈现突发(burst)方式，即XR业务的数据是周期性生成的，通常1秒有60帧视频数据。也就是说，每16.6ms生成一个视频帧。由于一个视频帧中的数据量的尺寸可能太大，因此会被切分为几十个IP数据包。也就是说，对传输XR业务的网络来说，每16.6ms需要传输几十个IP数据包，并且IP数据包的到达时间具有不确定性，大概范围在[-4,4]ms，或[-5,5]ms内，且服从截断高斯分布。It should be noted that XR services are mainly video services, and the data of this video service is in a burst mode, that is, the data of the XR service is generated periodically, usually with 60 frames of video data in 1 second. In other words, a video frame is generated every 16.6ms. Since the size of the data in a video frame may be too large, it will be divided into dozens of IP packets. In other words, for the network that transmits XR services, dozens of IP packets need to be transmitted every 16.6ms, and the arrival time of the IP packets is uncertain, roughly in the range of [-4,4]ms, or [-5,5]ms, and obeys the truncated Gaussian distribution.
2)业务的数据2) Business data
需要说明的是，本申请实施例的业务的数据可以具有低时延、高可靠、数据量大等特性。It should be noted that the data of the business in the embodiments of the present application can have the characteristics of low latency, high reliability, and large data volume.
具体的，本申请实施例的业务的数据，可以是业务的下行数据。对此，该业务的数据可以是由核心网(core network，CN)中的设备或应用服务器先下发给网络设备，再由网络设备下发给终端设备；当然，该业务的数据以是预先存储在网络设备中，以便网络设备直接下发给终端设备。Specifically, the data of the service of the embodiment of the present application may be downlink data of the service. In this regard, the data of the service may be first sent by a device or application server in a core network (CN) to a network device, and then sent by the network device to a terminal device; of course, the data of the service may be pre-stored in the network device so that the network device can directly send it to the terminal device.
具体的，核心网(core network，CN)中的设备，可以包括会话管理功能(Session Management Function，SMF)访问、移动性管理功能(access and mobility management function，AMF)、用户面功能(user plane function，UPF)等。Specifically, the equipment in the core network (CN) may include session management function (SMF), access and mobility management function (AMF), user plane function (UPF), etc.

又例如，应用服务器可以是云服务器、硬件服务器、软件服务器、软硬件服务器、web服务器、负载均衡器(Nginx)、数据中心网络设备、个人计算机(personal computer，PC)、计算设备、支持802.11协议的计算机等，对此不作具体限制。For another example, the application server can be a cloud server, a hardware server, a software server, a hardware and software server, a web server, a load balancer (Nginx), a data center network device, a personal computer (PC), a computing device, a computer that supports the 802.11 protocol, etc., without specific limitation.
3)业务的数据分布特性3) Data distribution characteristics of the business
①描述①Description
需要说明的是，本申请实施例的业务可以具有数据分布特征。其中，数据分布特征可以用于表示通过数据统计来描述业务的数据在周期、数据量、生成时刻、数据包位置分布等中的至少之一项上的分布情况/分布特征/分布规律/特性等。It should be noted that the services of the embodiments of the present application may have data distribution characteristics. The data distribution characteristics may be used to represent the distribution of data of the service described by data statistics in at least one of the period, data volume, generation time, data packet location distribution, etc./distribution characteristics/distribution law/characteristics, etc.
对于生成时刻，当忽略数据从生成至最终发送成功之间所需占用的时间，生成时刻可以是发送时刻/下发时刻。For the generation time, when the time required for data to be generated and finally sent successfully is ignored, the generation time can be the sending time/distribution time.
对于到达时刻，当忽略数据从达到至最终接收成功之间所需占用的时间，达到时刻可以是接收时刻。For the arrival time, when the time required for the data to arrive and be finally received successfully is ignored, the arrival time can be the receiving time.
②时刻② Moment
需要说明的是，本申请实施例所述的“时刻”，可以通过时间单元来表征/表示/描述。其中，时间单元可以表示在时域上的通信粒度，即在时域上是以时间单元为粒度/单位进行通信。It should be noted that the "moment" described in the embodiments of the present application can be characterized/expressed/described by a time unit, wherein the time unit can represent the communication granularity in the time domain, that is, communication is performed in the time domain with the time unit as the granularity/unit.
具体的，时间单元可以为超帧、无线帧、子帧、时隙、符号、迷你时隙、绝对时间单位等，对此不做限定。Specifically, the time unit may be a superframe, a radio frame, a subframe, a time slot, a symbol, a mini time slot, an absolute time unit, etc., and there is no limitation on this.
例如，以时间单元为时隙为例，生成时刻可以指示生成业务的数据所在的时隙。For example, taking the time unit as a time slot as an example, the generation time may indicate the time slot where the data of the generated service is located.
具体的，在5G NR的帧结构中，一个无线帧的时长固定为10ms，每个无线帧包含10个子帧，即每个子帧的时长固定为1ms。每个子帧包含若干(如1/2/4/816/32等)个时隙，例如当子载波间隔为15KHz时，每个子帧包含1个时隙，即每个时隙为1ms。每个时隙包含14或12个OFDM符号。另外，5G NR的传输时间间隔(transmission time interval，TTI)为1个时隙。Specifically, in the frame structure of 5G NR, the duration of a radio frame is fixed at 10ms, and each radio frame contains 10 subframes, that is, the duration of each subframe is fixed at 1ms. Each subframe contains several (such as 1/2/4/816/32, etc.) time slots. For example, when the subcarrier spacing is 15KHz, each subframe contains 1 time slot, that is, each time slot is 1ms. Each time slot contains 14 or 12 OFDM symbols. In addition, the transmission time interval (TTI) of 5G NR is 1 time slot.
具体的，若时间单元为超帧/无线帧/子帧/时隙/符号/迷你时隙等，则超帧/无线帧/子帧/时隙/符号/迷你时隙等也可以由绝对时间单位映射得到，对此不作具体限制。Specifically, if the time unit is a superframe/radio frame/subframe/time slot/symbol/mini time slot, etc., then the superframe/radio frame/subframe/time slot/symbol/mini time slot, etc. can also be mapped from the absolute time unit, and there is no specific limitation on this.

③Types of data distribution characteristics
结合上述描述，本申请实施例的数据分布特征可以包括以下至少一项：数据生成时刻、数据生成周期、数据量范围、数据生成时刻的抖动范围等。In combination with the above description, the data distribution characteristics of the embodiments of the present application may include at least one of the following: data generation time, data generation cycle, data volume range, jitter range of data generation time, etc.
下面分别进行具体说明。The following are detailed explanations respectively.
a)数据生成时刻a) Data generation time
◆描述Description
在本申请实施例中，对于下行，数据生成时刻，可以是指应用服务器生成业务的数据的时刻。另外，应用服务器可以将生成的业务的数据，发送给核心网中的设备，再由核心网中的设备下发给网络设备，对此不作具体限制。In the embodiment of the present application, for downlink, the data generation time may refer to the time when the application server generates the service data. In addition, the application server may send the generated service data to the device in the core network, and then the device in the core network sends it to the network device, without specific limitation.
◆数据发送时刻◆Data sending time
为了简化计算，本申请实施例可以忽略业务的数据从应用层到接入层的处理时延/处理时间。因此，应用层上生成业务的数据的时刻，即数据生成时刻，可以为数据从应用层到达物理层(或接入层)以进行发送的时刻，即数据发送时刻。In order to simplify the calculation, the processing delay/processing time of the service data from the application layer to the access layer can be ignored in the embodiment of the present application. Therefore, the time when the service data is generated on the application layer, that is, the data generation time, can be the time when the data reaches the physical layer (or access layer) from the application layer for transmission, that is, the data transmission time.
也就是说，数据生成时刻，也可以是指从应用层到达物理层(或接入层)以准备进行发送的时间。因此，数据生成时刻，可以等效于数据发送时刻。That is to say, the data generation time may also refer to the time when the data arrives at the physical layer (or access layer) from the application layer to prepare for transmission. Therefore, the data generation time may be equivalent to the data transmission time.
◆接入层◆Access layer
需要说明的是，接入层，可以理解为，除应用层之外的协议栈。It should be noted that the access layer can be understood as the protocol stack excluding the application layer.
例如，接入层可以为用户面协议栈或者控制面协议栈。其中，用户面(User Plane，UP)协议栈可以包括服务数据适配协议(Service Data Adaptation Protocol，SDAP)层、分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)层、无线链路控制(Radio Link Control，RLC)层、媒体接入控制(Medium Access Control，MAC)层和物理(Physical，PHY)层；控制面(Control Plane，CP)协议栈包括非接入层(Non-Access Stratum，NAS)、无线资源控制(Radio Resource Control，RRC)层、PDCP层、RLC层、MAC层和PHY层。For example, the access layer can be a user plane protocol stack or a control plane protocol stack. The user plane (UP) protocol stack can include a service data adaptation protocol (SDAP) layer, a packet data convergence protocol (PDCP) layer, a radio link control (RLC) layer, a medium access control (MAC) layer and a physical (PHY) layer; the control plane (CP) protocol stack includes a non-access stratum (NAS), a radio resource control (RRC) layer, a PDCP layer, an RLC layer, a MAC layer and a PHY layer.
具体的，在数据传输过程中，SDAP层可以将IP数据包映射到不同的无线承载(radio bearer，RB)。通常，来自或去往更高协议层的数据实体称为服务数据单元(service data unit，SDU)，而来自或者去往较低协议层的数据实体称为协议数据单元(protocol data unit，PDU)。因此，SDAP层通过向IP数据包添加SDAP报头以向PDCP层输出SDAP PDU，而PDCP层向SDAP层输出PDCP SDU，SDAP PDU等价于PDCP SDU。Specifically, during data transmission, the SDAP layer can map IP data packets to different radio bearers (RBs). Generally, the data entity from or to a higher protocol layer is called a service data unit (SDU), while the data entity from or to a lower protocol layer is called a protocol data unit (PDU). Therefore, the SDAP layer outputs SDAP PDU to the PDCP layer by adding an SDAP header to the IP data packet, and the PDCP layer outputs PDCP SDU to the SDAP layer. SDAP PDU is equivalent to PDCP SDU.
具体的，PDCP层可以通过向SDAP PDU添加PDCP报头以向RLC层输出PDCP PDU。RLC层通过向PDCP PDU添加RLC报头以向MAC层输出RLC PDU。Specifically, the PDCP layer may output the PDCP PDU to the RLC layer by adding a PDCP header to the SDAP PDU. The RLC layer may output the RLC PDU to the MAC layer by adding an RLC header to the PDCP PDU.
具体的，MAC层会对多个RLC PDU进行复用并添加MAC报头以形成传输块(transport block，TB)，并最终由PHY层对TB进行信道编码、调制、多天线处理以及资源映射等处理以传输。Specifically, the MAC layer multiplexes multiple RLC PDUs and adds a MAC header to form a transport block (TB). Finally, the PHY layer performs channel coding, modulation, multi-antenna processing, and resource mapping on the TB for transmission.
b)数据生成周期b) Data generation cycle
◆描述Description
在本申请实施例中，对于下行，应用服务器每次所生成的业务的数据，可能具有周期性。也就是说，数据生成时刻/数据发送时刻可能具有周期性。另外，应用服务器可以将生成的业务的数据，发送给核心网中的设备，再由核心网中的设备下发给网络设备，对此不作具体限制。In the embodiment of the present application, for downlink, the service data generated by the application server each time may have periodicity. That is, the data generation time/data transmission time may have periodicity. In addition, the application server may send the generated service data to the device in the core network, and then the device in the core network sends it to the network device, and there is no specific limitation on this.
例如，以生成的XR业务的数据为例，应用服务器可以周期性的生成一帧视频。同一帧视频的多个数据包可以组成一个突发(burst)，即每次burst包含多个数据包，集中到达接入层，等待通过空口传输。其中，应用服务器可以每秒周期性的下发60个帧视频，即每16.67ms就有一次burst需要传输，即XR业务的数据生成周期为16.67ms(约17ms)，每次burst包含多个数据包，而每次burst的数据量可能会在一定范围内波动。For example, taking the data generated for the XR service as an example, the application server can periodically generate a frame of video. Multiple data packets of the same frame of video can form a burst, that is, each burst contains multiple data packets, which arrive at the access layer in a concentrated manner and wait for transmission through the air interface. Among them, the application server can periodically send down 60 frames of video per second, that is, there is a burst to be transmitted every 16.67ms, that is, the data generation cycle of the XR service is 16.67ms (about 17ms), each burst contains multiple data packets, and the amount of data in each burst may fluctuate within a certain range.
◆数据生成周期的表示方式◆How to express the data generation cycle
具体的，结合上述“②时刻”中的内容，数据生成周期可以由时间单元为粒度进行表示。Specifically, in combination with the content in the above “② Moment”, the data generation cycle can be represented by a time unit as a granularity.
例如，以时间单元为绝对时间单位为例，若数据生成周期为17ms(如每秒输出60个帧，即每16.67ms(约17ms)就有一次burst需要传输)，则当前burst在2022年11月15日17时15分32秒267ms到达接入层，而下一次burst将在2022年11月15日17时15分32秒284ms到达接入层。For example, taking the time unit as the absolute time unit, if the data generation cycle is 17ms (such as 60 frames are output per second, that is, there is a burst to be transmitted every 16.67ms (about 17ms)), then the current burst will arrive at the access layer at 17:15:32:267ms on November 15, 2022, and the next burst will arrive at the access layer at 17:15:32:284ms on November 15, 2022.
又例如，以时间单元为时隙为例，若数据生成周期为17个时隙(如1个时隙为1ms)，则当前burst在时隙20(该数字20表示时隙的索引)到达接入层，而下一次burst将在时隙37到达接入层。For another example, taking the time unit as a time slot, if the data generation cycle is 17 time slots (such as 1 time slot is 1 ms), the current burst arrives at the access layer at time slot 20 (the number 20 represents the index of the time slot), and the next burst will arrive at the access layer at time slot 37.
c)数据量范围c) Data volume range
需要说明的是，由于每次可能是周期性生成业务的数据，而每次所生成的业务的数据可以由多个数据包组成，而不同数据包又可能具有不同的数据量大小，因此每次所生成的业务的数据的数据量可能会
在一定范围内波动。It should be noted that, since the service data may be generated periodically each time, and the service data generated each time may be composed of multiple data packets, and different data packets may have different data volumes, the data volume of the service data generated each time may be different. Fluctuates within a certain range.
基于此，数据量范围，可以用于表示每次所生成的业务的数据的最小数据量与最大数据量之间的范围。Based on this, the data volume range can be used to represent the range between the minimum data volume and the maximum data volume of the data of the service generated each time.
例如，以上述举例为例，由于每次burst包含多个数据包，而不同的数据包具有不同的数据量，因此每次所生成的burst的数据量可能存在不同，并且每次所生成的burst具有最小数据量与最大数据量之间的范围。For example, taking the above example, since each burst contains multiple data packets and different data packets have different data volumes, the data volume of each generated burst may be different, and each generated burst has a range between a minimum data volume and a maximum data volume.
d)数据生成时刻的抖动范围d) Jitter range at the time of data generation
需要说明的是，数据生成时刻的抖动范围，可以用于表示数据生成时刻的最大取值与最下取值之间的范围。It should be noted that the jitter range at the data generation time can be used to represent the range between the maximum value and the minimum value at the data generation time.
4)业务的数据递交特性4) Data delivery characteristics of the business
①描述①Description
需要说明的是，本申请实施例引入业务的数据递交特性，通过数据递交特性来描述终端设备在接收到业务的数据之后向上层递交该业务的数据的相关特性，从而实现业务的数据特性的增强，增强业务的数据传输，丰富用户使用该业务的场景，以及满足用户更多的业务使用需求。It should be noted that the embodiment of the present application introduces the data delivery characteristics of the service, and uses the data delivery characteristics to describe the relevant characteristics of the terminal device submitting the data of the service to the upper layer after receiving the data of the service, thereby enhancing the data characteristics of the service, enhancing the data transmission of the service, enriching the scenarios in which users use the service, and meeting more service usage needs of users.
②上层②Upper
结合上述“a)数据生成时刻”中的接入层的描述，本申请实施例所述的“上层”，可以包括除PHY层之外的接入层，可以包括应用层和除PHY层之外的接入层，可以包括PDCP层和PDCP层以上的协议栈层，可以包括接入层以上的协议层，可以包括SDAP以上的协议层，可以包括除PHY层之外的协议栈层等，对此不作具体限制。In combination with the description of the access layer in the above “a) data generation moment”, the “upper layer” described in the embodiments of the present application may include the access layer other than the PHY layer, may include the application layer and the access layer other than the PHY layer, may include the PDCP layer and the protocol stack layer above the PDCP layer, may include the protocol layer above the access layer, may include the protocol layer above the SDAP, may include the protocol stack layer other than the PHY layer, etc., without specific limitation.
例如，该上层可以包括PDCP层、SDAP层和应用层等。For example, the upper layer may include a PDCP layer, a SDAP layer, an application layer, and the like.
③数据递交特性的类型③Types of data delivery characteristics
在本申请实施例中，数据递交特性，可以包括以下至少之一项：In the embodiment of the present application, the data delivery characteristics may include at least one of the following:
数据递交时刻、第一数据时刻差、数据递交顺序、数据递交序号类型、数据递交丢弃状态、数据递交时刻补偿、数据递交时刻调整。Data submission time, first data time difference, data submission order, data submission sequence number type, data submission discard status, data submission time compensation, data submission time adjustment.
下面分别进行具体说明。The following are detailed explanations respectively.
a)数据递交时刻a) Data submission time
◆描述Description
在本申请实施例中，数据递交时刻，可以是指终端设备在接收到业务的数据之后向上层递交的时刻。In the embodiment of the present application, the data delivery time may refer to the time when the terminal device delivers the service data to the upper layer after receiving the service data.
例如，以时间单元为绝对时间单位为例，若数据递交时刻为2022年11月15日14时15分32秒40ms，则当该14时15分32秒40ms到达时，终端设备需要将该14时15分32秒40ms之前所接收到的业务的数据(这些数据还未向上层递交过)向上层进行递交。For example, taking the time unit as an absolute time unit, if the data delivery time is 14:15:32:40ms on November 15, 2022, when 14:15:32:40ms arrives, the terminal device needs to deliver the service data received before 14:15:32:40ms (these data have not been delivered to the upper layer) to the upper layer.
又例如，以时间单元为时隙为例，若数据递交时刻为时隙8(该数字8表示时隙的索引)，则当时隙8达到时，终端设备需要将该时隙8之前所接收到的业务的数据(这些数据还未向上层递交过)向上层进行递交。For another example, taking the time unit as a time slot, if the data delivery time is time slot 8 (the number 8 represents the index of the time slot), when time slot 8 is reached, the terminal device needs to deliver the data of the service received before time slot 8 (these data have not been delivered to the upper layer) to the upper layer.
这样，通过引入数据递交时刻，在接收到业务的数据之后，终端设备可以获知需要何时向上层递交该业务的数据，以便有利于保证后续对该业务的数据的呈现。In this way, by introducing the data delivery time, after receiving the service data, the terminal device can know when to deliver the service data to the upper layer, so as to facilitate the subsequent presentation of the service data.
◆数据递交时刻的周期◆Data submission time cycle
在一些可能的实现中，该数据递交时刻可以具有周期性。In some possible implementations, the data delivery timing may be periodic.
例如，以时间单元为***帧(由***帧号(System Frame Number,SFN)标识)为例，若数据递交时刻满足SFN mod 16＝0，则终端设备需要在SFN＝0、16、32、48…时向上层递交业务的数据，即数据递交时刻的周期为16个SFN；其中，若终端设备在SFN＝0时已向上层递交了缓存内所接收到的数据后，缓存变空，则当SFN＝16时，终端设备向上层递交的数据，这些数据是在SFN为0至16之内所接收到的并缓存的；若终端设备在SFN＝0时只向上层递交了缓存内部分所接收的数据后，缓存内还有剩余数据未递交，则当SFN＝16时，终端设备向上层递交的数据，这些数据是缓存内还未递交的，且这些数据可以是之前所剩余的，也可以是在SFN为0至16之内所接收到的。For example, taking the time unit as a system frame (identified by a system frame number (SFN)), if the data delivery time satisfies SFN mod 16 = 0, the terminal device needs to deliver the service data to the upper layer when SFN = 0, 16, 32, 48..., that is, the period of the data delivery time is 16 SFNs; wherein, if the terminal device has delivered the received data in the cache to the upper layer at SFN = 0, and the cache becomes empty, then when SFN = 16, the data delivered to the upper layer by the terminal device are the data received and cached within a range of SFN from 0 to 16; if the terminal device has delivered only part of the received data in the cache to the upper layer at SFN = 0, and there is still data remaining in the cache that has not been delivered, then when SFN = 16, the data delivered to the upper layer by the terminal device are the data that has not been delivered in the cache, and these data may be the remaining data from before, or the data received within a range of SFN from 0 to 16.
若数据递交时刻满足SFN mod 16＝1，则终端设备需要在SFN＝1、17、33、49…时向上层递交业务的数据，即数据递交时刻的周期为16个SFN。If the data delivery time satisfies SFN mod 16 = 1, the terminal device needs to deliver the service data to the upper layer when SFN = 1, 17, 33, 49..., that is, the period of the data delivery time is 16 SFNs.
可见，通过配置/指示/确定数据递交时刻的周期，就可以只需配置/指示/确定一次数据递交时刻。这样，终端设备就可以根据该次数据递交时刻以及该周期确定出后续每次的数据递交时刻，以便提高效率，节省开销等。It can be seen that by configuring/indicating/determining the cycle of the data delivery time, it is only necessary to configure/indicate/determine the data delivery time once. In this way, the terminal device can determine the subsequent data delivery time each time according to the data delivery time and the cycle, so as to improve efficiency and save costs.
◆多个终端设备下的数据递交时刻
◆Data delivery time for multiple terminal devices
在本申请实施例中，由于存在需要向多个用户均提供业务的场景，因此业务的数据可能需要传输给多个终端设备。因此，多个终端设备所接收的业务均具有数据递交时刻。In the embodiment of the present application, since there is a scenario where a service needs to be provided to multiple users, the data of the service may need to be transmitted to multiple terminal devices. Therefore, the services received by the multiple terminal devices all have data delivery times.
具体的，该多个终端设备所接收的业务，可以是同一类型的业务，也可以是不同类型的业务，对此不作具体限制。Specifically, the services received by the multiple terminal devices may be services of the same type or services of different types, and there is no specific limitation on this.
具体的，该多个终端设备所接收的业务的数据，可以是同一个业务的数据，可以是同一个业务的同一个数据，可以是同一个业务的不同数据，可以是不同业务的数据，对此不作具体限制。Specifically, the data of the services received by the multiple terminal devices may be data of the same service, the same data of the same service, different data of the same service, or data of different services, and there is no specific limitation on this.
需要说明的是，本申请实施例出现的所有以业务为XR业务为例的说明，并不限于XR业务，还可以是其他类型的业务(如AR/VR等)，且所有具有多用户递交耦合关系的业务，都属于本申请所要求保护的范围，对此不再赘述。It should be noted that all descriptions of the XR business as an example in the embodiments of the present application are not limited to XR business, but can also be other types of business (such as AR/VR, etc.), and all businesses with multi-user delivery coupling relationships are within the scope of protection required by this application, and will not be repeated here.
例如，以两个终端设备为例，该两个终端设备均接收XR业务的数据；For example, taking two terminal devices as an example, both of the terminal devices receive data of the XR service;
或者，一个终端设备可能接收XR业务的数据A，另一个终端设备可能需要接收XR业务的数据B，数据A和数据B为不同的数据；Alternatively, one terminal device may receive data A of the XR service, and another terminal device may need to receive data B of the XR service, where data A and data B are different data;
或者，一个终端设备可能接收XR业务的数据，另一个终端设备可能需要接收AR业务的数据等。Alternatively, one terminal device may receive data for an XR service, while another terminal device may need to receive data for an AR service, and so on.
另外，需要说明的是，由于多个用户所需的业务的数据之间可能具有一定的同步关系，因此多个终端设备所需接收的业务的数据递交时刻之间可能需要保证一定的同步关系。In addition, it should be noted that, since the data of services required by multiple users may have a certain synchronization relationship, the data delivery times of services required to be received by multiple terminal devices may need to ensure a certain synchronization relationship.
例如，以多个用户联机玩同一款游戏为例，该多个用户在同时玩游戏时，在游戏过程中可能需要保证游戏画面之间的同步，避免带有视觉上的较大差异，影响游戏体现。For example, when multiple users play the same game online, the multiple users may need to ensure synchronization between the game screens during the game to avoid large visual differences that affect the game experience.
具体的，该同步关系，可以是指不同终端设备之间所需接收的业务的数据递交时刻是相同的。Specifically, the synchronization relationship may mean that the data delivery time of the services to be received by different terminal devices is the same.
可以理解为，不同终端设备之间需要同时向上层递交业务的数据。It can be understood that different terminal devices need to submit service data to the upper layer at the same time.
例如，以两个终端设备且核心网中的设备为SMF为例，如图2所示，网络设备220在时刻A1接收到来自SMF 210的业务数据(或者说，业务的数据在时刻A1从SMF 210到达网络设备220等)。然后，终端设备2301在时刻B1接收到来自网络设备220的业务的数据，而终端设备2302在时刻C1接收到来自网络设备220的业务的数据。其中，终端设备2301和终端设备2302均需要等到时刻D1，再同时向上层递交各自所接收到的数据。For example, taking two terminal devices and the device in the core network as SMF, as shown in FIG2, the network device 220 receives the service data from the SMF 210 at time A1 (or the service data arrives at the network device 220 from the SMF 210 at time A1, etc.). Then, the terminal device 2301 receives the service data from the network device 220 at time B1, and the terminal device 2302 receives the service data from the network device 220 at time C1. Among them, both the terminal device 2301 and the terminal device 2302 need to wait until time D1, and then submit their received data to the upper layer at the same time.
具体的，该同步关系，可以是指不同终端设备之间所需接收的业务的数据递交时刻是前后相互关联的。Specifically, the synchronization relationship may mean that the data delivery moments of services to be received by different terminal devices are correlated with each other.
可以理解为，虽然不同终端设备之间需要按照先后的顺序分别向上层递交各自所接收到的数据，但是各自之间的数据递交时刻之间存在一定的关联关系。It can be understood that, although different terminal devices need to submit their received data to the upper layer in a certain order, there is a certain correlation between the data submission times between them.
例如，以两个终端设备且核心网中的设备为SMF为例，如图3所示，网络设备320在时刻A2接收到来自SMF 310的业务数据(或者说，业务的数据在时刻A2从SMF 310到达网络设备320等)。然后，终端设备3301在时刻B2接收到来自网络设备320的业务的数据，而终端设备3302在时刻C2接收到来自网络设备320的业务的数据。其中，终端设备3301需要等到时刻D2以向上层递交自身所接收到的数据，而终端设备3302需要等到时刻E2以向上层递交自身所接收到的数据。For example, taking two terminal devices and the device in the core network being SMF as an example, as shown in FIG3 , the network device 320 receives the service data from the SMF 310 at time A2 (or the service data arrives at the network device 320 from the SMF 310 at time A2, etc.). Then, the terminal device 3301 receives the service data from the network device 320 at time B2, and the terminal device 3302 receives the service data from the network device 320 at time C2. Among them, the terminal device 3301 needs to wait until time D2 to submit the received data to the upper layer, and the terminal device 3302 needs to wait until time E2 to submit the received data to the upper layer.
综上所述，为了便于区分和描述上述中的“多个终端设备”和“同步关系”，本申请实施例引入第一终端设备和第二终端设备，第一终端设备和第二终端设备为不同的两个终端设备，且均需要接收业务的数据。To summarize, in order to facilitate the distinction and description of the "multiple terminal devices" and "synchronization relationship" mentioned above, the embodiment of the present application introduces a first terminal device and a second terminal device. The first terminal device and the second terminal device are two different terminal devices, and both need to receive service data.
其中，第一终端设备在接收到业务的数据之后向上层递交的时刻，需要同步于第二终端设备在接收到业务的数据之后向上层递交的时刻。The moment when the first terminal device submits the received service data to the upper layer needs to be synchronized with the moment when the second terminal device submits the received service data to the upper layer.
也就是说，第一终端设备在接收到业务的数据之后向上层递交的时刻，与第二终端设备在接收到业务的数据之后向上层递交的时刻可以是相同的/同时的，可以是先后关联的等。That is to say, the moment when the first terminal device submits the received service data to the upper layer and the moment when the second terminal device submits the received service data to the upper layer may be the same/simultaneous, or may be sequentially related.
这样，有利于实现在需要向多个用户均提供业务的场景下多个终端设备的数据递交时刻的同步关系，增强业务的数据特性，增强业务的数据传输，丰富用户使用该业务的场景，以及满足用户更多的业务使用需求。This is conducive to achieving the synchronization relationship of data delivery moments of multiple terminal devices in scenarios where services need to be provided to multiple users, enhancing the data characteristics of the services, enhancing the data transmission of the services, enriching the scenarios in which users use the services, and meeting more user service usage needs.
具体的，第一终端设备与第二终端设备可以是在同一个小区下，可以是分别在不同小区下，可以是同一个网络设备下，可以是分别在不同网络设备下，对此不作具体限制。Specifically, the first terminal device and the second terminal device may be in the same cell or in different cells, may be in the same network device or in different network devices, and there is no specific limitation on this.
例如，如图4所示，第一终端设备在网络设备4201下，第二终端设备在网络设备4202下。For example, as shown in FIG. 4 , the first terminal device is under the network device 4201 , and the second terminal device is under the network device 4202 .
在图4的(a)中，SMF 410将第一终端设备和第二终端设备各自所需的业务的数据统一下发给网络设备4201，再由网络设备4201将第二终端设备所需的业务的数据发送给网络设备4202。然后，网络设备4201向第一终端设备发送数据，以及网络设备4202向第二终端设备发送数据。其中，第一终端设备在接收到业务的数据之后向上层递交的时刻，需要同步于第二终端设备在接收到业务的数据之后向上层递交的时刻。
In (a) of FIG4 , SMF 410 sends the data of the services required by the first terminal device and the second terminal device to network device 4201, and network device 4201 sends the data of the services required by the second terminal device to network device 4202. Then, network device 4201 sends data to the first terminal device, and network device 4202 sends data to the second terminal device. The moment when the first terminal device submits the service data to the upper layer after receiving it needs to be synchronized with the moment when the second terminal device submits the service data to the upper layer after receiving it.
在图4的(b)中，SMF 410将第一终端设备所需的业务的数据下发给网络设备4201，以及将第二终端设备所需的业务的数据下发给网络设备4202。然后，网络设备4201向第一终端设备发送数据，以及网络设备4202向第二终端设备发送数据。其中，第一终端设备在接收到数据之后向上层递交的时刻，需要同步于第二终端设备在接收到数据之后向上层递交的时刻。In (b) of FIG4 , SMF 410 sends data of the service required by the first terminal device to network device 4201, and sends data of the service required by the second terminal device to network device 4202. Then, network device 4201 sends data to the first terminal device, and network device 4202 sends data to the second terminal device. The moment when the first terminal device submits the data to the upper layer after receiving it needs to be synchronized with the moment when the second terminal device submits the data to the upper layer after receiving it.
b)第一数据时刻差b) First data time difference
◆描述Description
由于终端设备可以获知业务的数据从网络设备达到自身的时刻(或者说，终端设备可以获知自身接收到数据的时刻，该时刻称为“第一数据到达时刻”)，因此为了保证终端设备能够获知数据递交时刻，本申请实施例可以引入第一数据时刻差，该第一数据时刻差可以是指第一数据到达时刻与数据递交时刻之间的差值。Since the terminal device can know the moment when the data of the service reaches itself from the network device (or, the terminal device can know the moment when it receives the data, which is called the "first data arrival moment"), in order to ensure that the terminal device can know the data delivery moment, the embodiment of the present application can introduce a first data time difference, which can refer to the difference between the first data arrival moment and the data delivery moment.
这样，终端设备可以根据第一数据到达时刻和第一数据时刻差确定出上述所述的数据递交时刻，以便在接收到业务的数据之后，终端设备可以获知需要何时向上层递交该业务的数据，以便有利于保证后续对该业务的数据的呈现。In this way, the terminal device can determine the data delivery time mentioned above based on the first data arrival time and the first data time difference, so that after receiving the service data, the terminal device can know when to submit the service data to the upper layer, so as to facilitate the subsequent presentation of the service data.
例如，以时间单元为绝对时间单位为例，若第一数据时刻差为2ms，则当业务的数据从网络设备达到终端设备的时刻(即第一数据到达时刻)为2022年11月15日14时15分32秒40ms时，终端设备需要在2022年11月15日14时15分32秒42ms将所接收到的业务的数据向上层进行递交。其中，在2022年11月15日14时15分32秒42ms所递交的这些数据可以是在2022年11月15日14时15分32秒40ms以及其之前所接收但还未递交的所有数据或部分数据。For example, taking the time unit as an absolute time unit, if the first data time difference is 2ms, when the time when the service data reaches the terminal device from the network device (i.e., the first data arrival time) is 14:15:32:40ms on November 15, 2022, the terminal device needs to submit the received service data to the upper layer at 14:15:32:42ms on November 15, 2022. The data submitted at 14:15:32:42ms on November 15, 2022 may be all or part of the data received but not submitted at 14:15:32:40ms on November 15, 2022 or before.
又例如，以时间单元为时隙为例，若第一数据时刻差为2个时隙，则当业务的数据从网络设备达到终端设备的时刻为时隙8(该数字8表示时隙的索引)时，终端设备需要在时隙10将所接收到的业务的数据向上层进行递交。其中，在时隙10所递交的这些数据可以是在时隙8以及其之前所接收但还未递交的所有数据或部分数据。For another example, taking the time unit as a time slot, if the first data time difference is 2 time slots, when the time when the service data arrives at the terminal device from the network device is time slot 8 (the number 8 represents the index of the time slot), the terminal device needs to submit the received service data to the upper layer in time slot 10. The data submitted in time slot 10 can be all or part of the data received in time slot 8 and before but not yet submitted.
◆多个终端设备下的第一数据时刻差◆The first data time difference of multiple terminal devices
在本申请实施例中，由于存在需要向多个用户均提供业务的场景，因此业务的数据可能需要传输给多个终端设备。因此，多个终端设备所接收的业务均具有第一数据时刻差。In the embodiment of the present application, since there is a scenario where services need to be provided to multiple users, the data of the services may need to be transmitted to multiple terminal devices. Therefore, the services received by the multiple terminal devices all have a first data time difference.
具体的，该多个终端设备所接收的业务的第一数据时刻差，可以是相同的取值，也可以是不同的取值，对此不作具体限制。具体可以结合上述“多个终端设备下的数据递交时刻”中的内容进行理解，对此不再赘述。Specifically, the first data time difference of the services received by the multiple terminal devices can be the same value or different values, and there is no specific limitation on this. The specific understanding can be combined with the content of the above "data delivery time under multiple terminal devices", which will not be repeated.
c)数据递交顺序c) Data submission order
◆描述Description
需要说明的是，终端设备在当前时刻接收到业务的数据时，在该当前时刻之前终端设备可能还缓存有一些还未递交的数据，或者当前时刻所接收的数据本身由多个数据包组成。此时，在该当前时刻之后的某个时刻需要向上层递交数据时，终端设备所递交的数据中可能存存在业务的多个数据(或者多个数据包)，而这些数据本身之间可能存在一定的顺序(如数据的包头中本身携带有数据序列或者数据包序列)。It should be noted that when the terminal device receives the data of the service at the current moment, the terminal device may have cached some data that has not been delivered before the current moment, or the data received at the current moment itself consists of multiple data packets. At this time, when it is necessary to deliver data to the upper layer at a certain moment after the current moment, the data delivered by the terminal device may contain multiple data (or multiple data packets) of the service, and these data themselves may have a certain order (such as the data header itself carries a data sequence or a data packet sequence).
对此，本申请实施例引入数据递交顺序，该数据递交顺序可以是指终端设备在接收到业务的数据之后向上层递交所需按照的数据顺序。In this regard, the embodiment of the present application introduces a data delivery order, which may refer to the order in which the terminal device needs to deliver the data to the upper layer after receiving the service data.
例如，对于终端设备所接收到的业务的数据，当SFN mod 16＝0时，终端设备需要按照数据递交顺序，向上层递交一次缓存中尚未递交过的数据。For example, for the service data received by the terminal device, when SFN mod 16 = 0, the terminal device needs to submit the data in the cache that has not been submitted to the upper layer once according to the data submission order.
这样，本申请实施例可以根据数据递交顺序所指的数据顺序，将数据向上层进行递交，从而实现业务的数据特性的增强，增强业务的数据传输，丰富用户使用该业务的场景，以及满足用户更多的业务使用需求。In this way, the embodiment of the present application can submit data to the upper layer according to the data order referred to by the data submission order, thereby enhancing the data characteristics of the service, enhancing the data transmission of the service, enriching the scenarios in which users use the service, and meeting more user service usage needs.
具体的，数据递交顺序所指的数据顺序，可以是按照数据序号从小到大(或从大到小)的顺序向上层递交，按照数据包大小从小到大(或从大到小)的顺序向上层递交，可以是按照数据缓存的先后顺序向上层递交，可以是按照数据到达(接收)的先后顺序向上层递交等。Specifically, the data submission order refers to the data order, which can be submitted to the upper layer in the order of data sequence numbers from small to large (or from large to small), submitted to the upper layer in the order of data packet sizes from small to large (or from large to small), submitted to the upper layer in the order of data cache, submitted to the upper layer in the order of data arrival (reception), etc.
可见，本申请实施例可以按照各类顺序向上层递交数据，以便提高数据递交的灵活性和多样性。It can be seen that the embodiments of the present application can submit data to the upper layer in various orders to improve the flexibility and diversity of data submission.
◆多个终端设备下的数据递交顺序◆Data submission order under multiple terminal devices
在本申请实施例中，由于存在需要向多个用户均提供业务的场景，因此业务的数据可能需要传输给多个终端设备。因此，多个终端设备所接收的业务可能具有数据递交顺序。In the embodiment of the present application, since there is a scenario where services need to be provided to multiple users, the data of the services may need to be transmitted to multiple terminal devices. Therefore, the services received by the multiple terminal devices may have a data delivery order.
具体的，该多个终端设备各自所接收的业务的数据递交顺序之间，可以是相同的，也可以是不同的，对此不作具体限制。具体可以结合上述“多个终端设备下的数据递交时刻”中的内容进行理解，对此不再
赘述。Specifically, the data delivery order of the services received by the multiple terminal devices may be the same or different, and there is no specific limitation on this. This can be understood in conjunction with the content of the above-mentioned "data delivery time of multiple terminal devices", and no further explanation is given on this. Elaborate.
具体的，该多个终端设备中存在一些终端设备所接收的业务具有数据递交顺序，而另一些终端设备所接收的业务不具有数据递交顺序，具体由网络自行实现，从而可以根据不同场景/不同用户需求进行灵活的配置/指示。Specifically, among the multiple terminal devices, some terminal devices receive services with a data delivery order, while other terminal devices receive services without a data delivery order, which is specifically implemented by the network itself, so that flexible configuration/instructions can be performed according to different scenarios/different user needs.
例如，以第一终端设备和第二终端设备为例，网络设备可以配置/指示第一终端设备所接收的业务具有数据递交顺序，而第二终端设备所接收的业务具有数据递交顺序。这样，第一终端设备需要按照数据递交顺序进行数据递交，而第二终端设备无需按照数据递交顺序进行数据递交。For example, taking the first terminal device and the second terminal device as examples, the network device may configure/instruct that the service received by the first terminal device has a data delivery order, while the service received by the second terminal device has a data delivery order. In this way, the first terminal device needs to deliver data according to the data delivery order, while the second terminal device does not need to deliver data according to the data delivery order.
又例如，以第一终端设备和第二终端设备为例，网络设备可以配置/指示第一终端设备和第二终端设备各自所接收的业务均具有数据递交顺序。For another example, taking the first terminal device and the second terminal device as an example, the network device may configure/instruct the first terminal device and the second terminal device that the services received by each of them have a data delivery order.
又例如，以第一终端设备和第二终端设备为例，网络设备可以配置/指示第一终端设备和第二终端设备各自所接收的业务均不具有数据递交顺序。For another example, taking the first terminal device and the second terminal device as an example, the network device may configure/instruct the first terminal device and the second terminal device that the services received by each of the first terminal device and the second terminal device do not have a data delivery order.
d)数据递交序号类型d) Data submission sequence number type
◆描述Description
需要说明的是，结合上述“c)数据递交顺序”中的内容，本申请实施例可以按照数据序号从小到大(或从大到小)的顺序向上层递交。由于数据序列可能具有不同的类型，如数据序列的类型包括PDCP序号、IP序号、SDAP序号等，因此本申请实施例可以引入数据递交序号类型，该数据递交序号类型可以是指终端设备在接收到业务的数据之后向上层递交的数据顺序所需按照的数据序号类型。It should be noted that, in combination with the content in the above "c) Data submission order", the embodiment of the present application can submit to the upper layer in the order of data sequence numbers from small to large (or from large to small). Since data sequences may have different types, such as data sequence types including PDCP sequence numbers, IP sequence numbers, SDAP sequence numbers, etc., the embodiment of the present application can introduce a data submission sequence number type, which can refer to the data sequence number type that the terminal device needs to follow in the order of data submitted to the upper layer after receiving the data of the service.
这样，本申请实施例可以灵活按照数据序号类型来实现数据递交顺序，以提高数据递交的灵活性和多样性，从而实现业务的数据特性的增强，增强业务的数据传输，丰富用户使用该业务的场景，以及满足用户更多的业务使用需求。In this way, the embodiments of the present application can flexibly implement the data delivery order according to the data sequence number type to improve the flexibility and diversity of data delivery, thereby enhancing the data characteristics of the service, enhancing the data transmission of the service, enriching the scenarios in which users use the service, and meeting more user service usage needs.
◆多个终端设备下的数据递交序号类型◆Data submission sequence number type under multiple terminal devices
在本申请实施例中，由于存在需要向多个用户均提供业务的场景，因此业务的数据可能需要传输给多个终端设备。因此，多个终端设备所接收的业务可能具有数据递交序号类型。In the embodiment of the present application, since there is a scenario where services need to be provided to multiple users, the data of the services may need to be transmitted to multiple terminal devices. Therefore, the services received by the multiple terminal devices may have a data delivery sequence number type.
具体的，该多个终端设备各自所接收的业务的数据递交序号类型之间，可以是相同的，也可以是不同的，对此不作具体限制。Specifically, the data delivery sequence number types of the services received by the multiple terminal devices may be the same or different, and there is no specific limitation on this.
例如，以第一终端设备和第二终端设备，且数据递交序号类型是不同的为例，第一终端设备按照PDCP序号从小到大(或从大到小)的顺序向上层递交，而第一终端设备按照IP序号从小到大(或从大到小)的顺序向上层递交。For example, taking the first terminal device and the second terminal device, and the data submission sequence number types are different, the first terminal device submits to the upper layer in the order of PDCP sequence number from small to large (or from large to small), and the second terminal device submits to the upper layer in the order of IP sequence number from small to large (or from large to small).
具体的，该多个终端设备中存在一些终端设备所接收的业务具有数据递交序号类型，而另一些终端设备所接收的业务不具有数据递交序号类型，具体由网络自行实现，从而可以根据不同场景/不同用户需求进行灵活的配置/指示。Specifically, among the multiple terminal devices, some terminal devices receive services with a data delivery sequence number type, while other terminal devices receive services without a data delivery sequence number type. This is specifically implemented by the network itself, so that it can be flexibly configured/indicated according to different scenarios/different user needs.
例如，以第一终端设备和第二终端设备为例，网络设备可以配置/指示第一终端设备所接收的业务具有数据递交序号类型，而第二终端设备所接收的业务具有数据递交序号类型。这样，第一终端设备需要按照数据递交序号类型进行数据递交，而第二终端设备无需按照数据递交顺序进行数据递交。For example, taking the first terminal device and the second terminal device as examples, the network device can configure/indicate that the service received by the first terminal device has a data delivery sequence number type, while the service received by the second terminal device has a data delivery sequence number type. In this way, the first terminal device needs to deliver data according to the data delivery sequence number type, while the second terminal device does not need to deliver data according to the data delivery order.
e)数据递交丢弃状态e) Data submission discard status
◆描述Description
由于终端设备可能需要向上层递交多个数据(或多个数据包)，而有些数据可能无需进行递交，因此本申请实施例引入数据递交丢弃状态，该数据递交丢弃状态可以是指终端设备在接收到业务的数据之后向上层递交的数据所需按照的丢弃状态。该丢弃状态可以表示数据是递交，还是不递交。Since the terminal device may need to submit multiple data (or multiple data packets) to the upper layer, and some data may not need to be submitted, the embodiment of the present application introduces a data submission discard state, which may refer to the discard state that the terminal device needs to follow for the data submitted to the upper layer after receiving the service data. The discard state may indicate whether the data is submitted or not submitted.
例如，终端设备缓存有数据序号为1至7的多个数据。其中，终端设备只向上层递交数据序号为1至3的数据，而数据序号为5至7的数据不进行递交。For example, the terminal device caches a plurality of data with data sequence numbers from 1 to 7. The terminal device only submits the data with data sequence numbers from 1 to 3 to the upper layer, and does not submit the data with data sequence numbers from 5 to 7.
这样，本申请实施例可以灵活选择哪些数据需要向上层递交，哪些数据(比如重复传输的数据)无需向上层递交，以提高数据递交的灵活性和多样性，从而实现业务的数据特性的增强，增强业务的数据传输，丰富用户使用该业务的场景，以及满足用户更多的业务使用需求。In this way, the embodiments of the present application can flexibly select which data needs to be submitted to the upper layer and which data (such as repeatedly transmitted data) does not need to be submitted to the upper layer, so as to improve the flexibility and diversity of data submission, thereby enhancing the data characteristics of the service, enhancing the data transmission of the service, enriching the scenarios in which users use the service, and meeting more user service usage needs.
具体的，这些不递交的数据，可以继续进行缓存，也可以直接删除。Specifically, the undelivered data can continue to be cached or directly deleted.
◆多个终端设备下的数据递交丢弃状态◆Data delivery and discard status under multiple terminal devices
在本申请实施例中，由于存在需要向多个用户均提供业务的场景，因此业务的数据可能需要传输给多个终端设备。因此，多个终端设备所接收的业务可能具有数据递交丢弃状态。In the embodiment of the present application, since there is a scenario where services need to be provided to multiple users, the data of the services may need to be transmitted to multiple terminal devices. Therefore, the services received by the multiple terminal devices may have a data delivery discarded state.
具体的，该多个终端设备各自所接收的业务的数据递交丢弃状态之间，可以是相同的，也可以是不同的，对此不作具体限制。Specifically, the data delivery and discarding states of the services received by the multiple terminal devices may be the same or different, and there is no specific limitation on this.
具体的，该多个终端设备中存在一些终端设备所接收的业务具有数据递交丢弃状态，而另一些终端
设备所接收的业务不具有数据递交丢弃状态，具体由网络自行实现，从而可以根据不同场景/不同用户需求进行灵活的配置/指示。Specifically, some of the multiple terminal devices receive services in a data delivery discard state, while other terminal devices receive services in a data delivery discard state. The service received by the device does not have a data delivery discard state, which is specifically implemented by the network itself, so that it can be flexibly configured/indicated according to different scenarios/different user needs.
f)数据递交时刻补偿f) Data delivery time compensation
◆描述Description
需要说明的是，由于终端设备存在一定的移动性，因此终端设备可能从一个小区移动到另一个小区，或者可能从一个地理位置移动到另一个地理位置。It should be noted that, since the terminal device has certain mobility, the terminal device may move from one cell to another cell, or may move from one geographical location to another geographical location.
这样，当终端设备所处的小区或地理位置发生变化时，终端设备所确定/配置/指示的数据递交时刻也可能变化，而不再适配。In this way, when the cell or geographical location of the terminal device changes, the data delivery time determined/configured/indicated by the terminal device may also change and no longer adapt.
基于此，本申请实施例引入数据递交时刻补偿，该数据递交时刻补偿可以是指数据递交时刻在不同小区或者不同地理位置下的补偿。Based on this, the embodiment of the present application introduces data delivery time compensation, and the data delivery time compensation may refer to compensation of data delivery time in different cells or different geographical locations.
可见，当终端设备所处的小区或地理位置发生变化时，本申请实施例可以对数据递交时刻进行补偿，以便提高数据递交时刻的准确性，实现业务的数据特性的增强，增强业务的数据传输，丰富用户使用该业务的场景，以及满足用户更多的业务使用需求。It can be seen that when the cell or geographical location of the terminal device changes, the embodiment of the present application can compensate for the data delivery time so as to improve the accuracy of the data delivery time, enhance the data characteristics of the service, enhance the data transmission of the service, enrich the scenarios in which users use the service, and meet more user service usage needs.
例如，对于网络设备A的小区A和网络设备B的小区B，其SFN相差5(如在同一时刻下，小区A的SFN是0，小区B的SFN是5)，当网络设备A的小区A下的终端设备需要在SFN mod 16＝0时向上层递交数据时，若该终端设备移动到网络设备B的小区B下，则网络设备A与网络设备B之间可以协商对SFN mod 16＝0进行补偿，得到SFN mode 16＝5。如此，在小区B下的该终端设备需要在SFN mode 16＝5时向上层递交数据。For example, for cell A of network device A and cell B of network device B, the SFN difference is 5 (e.g., at the same time, the SFN of cell A is 0 and the SFN of cell B is 5). When the terminal device in cell A of network device A needs to submit data to the upper layer when SFN mod 16 = 0, if the terminal device moves to cell B of network device B, network device A and network device B can negotiate to compensate SFN mod 16 = 0 and obtain SFN mode 16 = 5. In this way, the terminal device in cell B needs to submit data to the upper layer when SFN mode 16 = 5.
当然，上述的数据递交时刻补偿，除了可以适用于同一个终端设备在不同小区或不同地理位置的情况，也可以适用于在不同小区或不同地理位置下的多个终端设备。Of course, the above-mentioned data delivery time compensation can be applied not only to the case where the same terminal device is in different cells or different geographical locations, but also to multiple terminal devices in different cells or different geographical locations.
例如，对于网络设备A的小区A和网络设备B的小区B，其SFN相差5(如在同一时刻下，小区A的SFN是0，小区B的SFN是5)，网络设备A与网络设备B之间可以协商如下：For example, for cell A of network device A and cell B of network device B, the SFN difference is 5 (e.g., at the same time, the SFN of cell A is 0 and the SFN of cell B is 5), network device A and network device B can negotiate as follows:
网络设备A的小区A下的第一终端设备需要在SFN mod 16＝0时向上层递交数据，而网络设备B的小区B下的第二终端设备需要在SFN mode 16＝5时向上层递交数据。这样，可以保证第一终端设备和第二终端设备在同一时刻上向上层递交数据，实现同步关系。The first terminal device under cell A of network device A needs to submit data to the upper layer when SFN mod 16 = 0, while the second terminal device under cell B of network device B needs to submit data to the upper layer when SFN mode 16 = 5. In this way, it can be ensured that the first terminal device and the second terminal device submit data to the upper layer at the same time, realizing a synchronous relationship.
◆多个终端设备下的数据递交时刻补偿◆Data delivery time compensation for multiple terminal devices
具体的，该多个终端设备各自所接收的业务的数据递交时刻补偿之间，可以是相同的，也可以是不同的，对此不作具体限制。Specifically, the data delivery time compensations of the services received by the multiple terminal devices may be the same or different, and there is no specific limitation on this.
具体的，该多个终端设备中存在一些终端设备所接收的业务具有数据递交时刻补偿，而另一些终端设备所接收的业务不具有数据递交时刻补偿，具体由网络自行实现，从而可以根据不同场景/不同用户需求进行灵活的配置/指示。Specifically, among the multiple terminal devices, some terminal devices receive services with data delivery time compensation, while other terminal devices receive services without data delivery time compensation. This is specifically implemented by the network itself, so that it can be flexibly configured/indicated according to different scenarios/different user needs.
g)数据递交时刻调整。g) Adjustment of data submission time.
◆描述Description
需要说明的是，随着网络配置/业务需求等因素的变动，原有终端设备所确定/配置/指示的数据递交时刻可能会发生变化，而不再适配。It should be noted that with changes in factors such as network configuration/business requirements, the data delivery time determined/configured/indicated by the original terminal device may change and no longer adapt.
基于此，本申请实施例引入数据递交时刻调整，该数据递交时刻调整可以是指数据递交时刻的调整。Based on this, the embodiment of the present application introduces data submission time adjustment, which may refer to the adjustment of data submission time.
可见，本申请实施例可以对数据递交时刻进行调整，以便提高数据递交时刻的灵活性和多样性，实现业务的数据特性的增强，增强业务的数据传输，丰富用户使用该业务的场景，以及满足用户更多的业务使用需求。It can be seen that the embodiments of the present application can adjust the data delivery time in order to improve the flexibility and diversity of the data delivery time, enhance the data characteristics of the service, enhance the data transmission of the service, enrich the scenarios in which users use the service, and meet more user service usage needs.
例如，终端设备原先需要在SFN mod 16＝0时向上层递交数据。现在需要调整为在SFN mode 16＝5时向上层递交数据。For example, the terminal device originally needs to submit data to the upper layer when SFN mod 16 = 0. Now it needs to be adjusted to submit data to the upper layer when SFN mode 16 = 5.
当然，上述的数据递交时刻补偿，除了可以适用于同一个终端设备的情况，也可以适用于多个终端设备。Of course, the above-mentioned data delivery time compensation can be applied not only to the same terminal device, but also to multiple terminal devices.
例如，第一终端设备和第二终端设备原先均需要在SFN mod 16＝0时向上层递交数据。现在，需要将第一终端设备调整为在SFN mode 16＝5时向上层递交数据，而第二终端设备的数据递交时刻不变。For example, the first terminal device and the second terminal device originally need to submit data to the upper layer when SFN mod 16 = 0. Now, the first terminal device needs to be adjusted to submit data to the upper layer when SFN mode 16 = 5, while the data submission time of the second terminal device remains unchanged.
具体的，网络设备可以根据业务特性和/或终端设备的地理位置调整据递交时刻。Specifically, the network device may adjust the data delivery time according to service characteristics and/or the geographical location of the terminal device.
例如，若第一终端设备的地理位置比第二终端设备更靠近业务的数据源，则网络设备可以调整第一终端设备比第二终端设备更早向上层递交数据，从而调整两个终端设备的数据递交时刻。For example, if the geographical location of the first terminal device is closer to the data source of the service than the second terminal device, the network device can adjust the first terminal device to submit data to the upper layer earlier than the second terminal device, thereby adjusting the data submission time of the two terminal devices.
◆多个终端设备下的数据递交时刻调整◆Adjustment of data delivery time for multiple terminal devices
具体的，该多个终端设备各自所接收的业务的数据递交时刻调整之间，可以是相同的，也可以是不同的，对此不作具体限制。
Specifically, the data delivery time adjustments of the services received by the multiple terminal devices may be the same or different, and there is no specific limitation on this.
具体的，该多个终端设备中存在一些终端设备所接收的业务具有数据递交时刻调整，而另一些终端设备所接收的业务不具有数据递交时刻调整，具体由网络自行实现，从而可以根据不同场景/不同用户需求进行灵活的配置/指示。Specifically, among the multiple terminal devices, some terminal devices receive services with data delivery time adjustment, while other terminal devices receive services without data delivery time adjustment, which is specifically implemented by the network itself, so that flexible configuration/instructions can be performed according to different scenarios/different user needs.
5)如何实现数据递交特性的配置/指示过程5) How to implement the configuration/instruction process of data submission features
①描述①Description
需要说明的是，本申请实施例的数据递交特性，可以是网络配置/指示、预配置、协议规定的，对此不作具体限制。It should be noted that the data delivery characteristics of the embodiments of the present application may be network configuration/indication, pre-configuration, or protocol regulations, and there is no specific limitation on this.
在一些可能的实现中，数据递交特性可以是通过控制面配置的和/或通过用户面指示的。In some possible implementations, the data delivery characteristics may be configured via the control plane and/or indicated via the user plane.
下面分别进行具体说明。The following are detailed explanations respectively.
②仅通过控制面配置②Configuration via control plane only
具体的，通过控制面配置，可以包括通过控制面信令配置。其中，该控制面信令可以包括RRC信令和/或MAC控制元素(Control CE)。Specifically, the control plane configuration may include configuration through control plane signaling. The control plane signaling may include RRC signaling and/or MAC control element (Control CE).
需要说明的是，网络设备可以根据控制面信令来向终端设备配置数据递交特性，从而实现通过控制面配置数据递交特性。It should be noted that the network device can configure the data delivery feature to the terminal device according to the control plane signaling, thereby realizing the data delivery feature configured through the control plane.
例如，网络设备可以通过RRC信令实现配置数据递交特性，可以通过MAC CE实现配置数据递交特性，可以通过RRC信令和MAC CE实现配置数据递交特性。For example, a network device may implement a configuration data delivery feature through RRC signaling, may implement a configuration data delivery feature through MAC CE, or may implement a configuration data delivery feature through RRC signaling and MAC CE.
进一步的，若该控制面信令可以包括RRC信令和MAC CE，则该RRC信令可以用于配置数据递交特性的多个候选，而该MAC CE可以用于从数据递交特性的多个候选中指示出一个。Further, if the control plane signaling may include RRC signaling and MAC CE, the RRC signaling may be used to configure multiple candidates for data delivery characteristics, and the MAC CE may be used to indicate one from the multiple candidates for data delivery characteristics.
需要说明的是，网络设备可以先通过RRC信令向终端设备配置数据递交特性的多个候选，再通过MAC CE从多个候选中指示出一个，从而实现向终端设备配置数据递交特性。It should be noted that the network device can first configure multiple candidates for data delivery characteristics to the terminal device through RRC signaling, and then indicate one from the multiple candidates through MAC CE, thereby realizing the configuration data delivery characteristics to the terminal device.
可选的，数据递交特性的多个候选各自具有一个标识(ID)或索引(index)，而MAC CE可以携带该多个标识或该多个索引中的一个，从而实现通过MAC CE从多个候选中指示出一个。Optionally, multiple candidates for the data delivery feature each have an identifier (ID) or an index (index), and the MAC CE can carry one of the multiple identifiers or the multiple indexes, thereby indicating one from the multiple candidates through the MAC CE.
③仅通过用户面指示③Only through user interface instructions
具体的，通过用户面指示，可以包括通过用户面信令指示。其中，该用户面信令可以包括下行控制信息(Downlink Control Information，DCI)或者MAC CE。Specifically, the user plane indication may include indication through user plane signaling. The user plane signaling may include downlink control information (Downlink Control Information, DCI) or MAC CE.
需要说明的是，网络设备可以根据用户面信令来向终端设备指示数据递交特性，从而实现通过用户面指示数据递交特性。It should be noted that the network device can indicate the data delivery characteristics to the terminal device according to the user plane signaling, thereby realizing the data delivery characteristics indicated through the user plane.
具体的，通过用户面指示，可以包括通过业务的数据所携带的信息指示。Specifically, the user plane indication may include information indication carried by service data.
需要说明的是，网络设备在向终端设备发下业务的数据时，可以直接通过该业务的数据所携带的信息来指示数据递交特性，而无需再单独利用信令来进行指示，以便节省信令开销。It should be noted that when the network device sends service data to the terminal device, it can directly indicate the data delivery characteristics through the information carried by the service data, without using signaling separately for indication, so as to save signaling overhead.
例如，该信息可以携带在业务的数据的MAC报头或者IP报头中。For example, the information may be carried in a MAC header or an IP header of the service data.
④通过控制面配置和通过用户面指示④Configuration through the control plane and indication through the user plane
需要说明的是，结合上述描述，本申请实施例可以通过控制面配置数据递交特性的多个候选，再通过用户面从多个候选中指示出一个，具体不再赘述。It should be noted that, in combination with the above description, the embodiment of the present application can configure multiple candidates for data delivery characteristics through the control plane, and then indicate one from the multiple candidates through the user plane, and the details will not be repeated.
例如，网络设备可以先通过控制面信令向终端设备配置数据递交特性的多个候选，再通过用户面指令或业务的数据所携带的信息从多个候选中指示出一个，从而实现向终端设备配置数据递交特性。For example, the network device may first configure multiple candidates of data delivery characteristics to the terminal device through control plane signaling, and then indicate one from the multiple candidates through user plane instructions or information carried in service data, thereby configuring data delivery characteristics to the terminal device.
6)如何确定数据递交特性6) How to determine data delivery characteristics
①描述①Description
结合上述“5)如何实现数据递交特性的配置/指示过程”中的内容，在网络配置/指示数据递交特性的实现方式中，本申请实施例的数据递交特性可以是由网络设备确定的，再由网络设备直接告知或者间接告知终端设备。Combined with the content of the above “5) How to implement the configuration/indication process of the data delivery characteristics”, in the implementation method of the network configuration/indication of the data delivery characteristics, the data delivery characteristics of the embodiment of the present application can be determined by the network device, and then directly or indirectly notified to the terminal device by the network device.
对于网络设备如何确定数据递交特性，可以存在如下实现方式。Regarding how the network device determines the data delivery characteristics, there may be the following implementations.
在一些可能的实现中，数据递交特性，可以是网络设备根据核心网中的设备或应用服务器所发送的递交要求信息确定的，可以是网络设备根据终端设备上报的递交期望信息确定的。In some possible implementations, the data delivery characteristics may be determined by the network device based on delivery requirement information sent by a device or application server in the core network, or may be determined by the network device based on delivery expectation information reported by a terminal device.
下面分别进行具体说明。The following are detailed explanations respectively.
②递交要求信息②Submit the required information
a)描述a) Description
需要说明的是，对于下行，由于业务的数据可以是由核心网中的设备或应用服务器下发给网络设备的，因此在下发业务的数据的过程，核心网中的设备或应用服务器需要告知网络设备该业务的相关递交要求，以便保证业务的数据特性等。It should be noted that for the downlink, since the service data can be sent from the equipment or application server in the core network to the network equipment, in the process of sending the service data, the equipment or application server in the core network needs to inform the network equipment of the relevant delivery requirements of the service in order to ensure the data characteristics of the service, etc.
具体实现时，核心网中的设备或应用服务器可以向网络设备发送递交要求信息，该递交要求信息可
以用于指示该业务的相关递交要求。In specific implementation, the device or application server in the core network can send a submission request message to the network device, and the submission request message can be To indicate the relevant submission requirements for the business.
这样，网络设备可以根据递交要求信息来确定数据递交特性，再告知给终端设备。In this way, the network device can determine the data delivery characteristics according to the delivery requirement information and then inform the terminal device.
具体的，该递交要求信息可以是根据上述的业务的数据分布特性确定。Specifically, the submission requirement information may be determined according to the data distribution characteristics of the above-mentioned service.
具体的，递交要求信息可以用于指示以下至少之一项：Specifically, the submission request information may be used to indicate at least one of the following:
递交时刻周期、第二数据时刻差、数据发送周期。Submission time period, second data time difference, data sending period.
下面分别进行具体说明。The following are detailed explanations respectively.
b)递交时刻周期b) Submission time period
需要说明的是，结合上述“a)数据递交时刻”的“数据递交时刻的周期”中的内容，数据递交时刻可以具有周期性。It should be noted that, in combination with the content of "periodicity of data submission time" in the above "a) data submission time", the data submission time may be periodic.
对此，本申请实施例引入递交时刻周期，该递交时刻周期可以是指数据递交时刻的周期。In this regard, the embodiment of the present application introduces a delivery time period, which may refer to a period of data delivery time.
可见，本申请实施例可以通过递交要求信息实现核心网中的设备或应用服务器来向网络设备配置/指示数据递交时刻的周期，再由网络设备向终端设备配置/指示该数据递交时刻的周期。It can be seen that the embodiments of the present application can enable the device or application server in the core network to configure/indicate the period of data submission time to the network device by submitting request information, and then the network device configures/indicates the period of data submission time to the terminal device.
这样，终端设备就可以根据数据递交时刻以及该数据递交时刻的周期确定出后续每次的数据递交时刻，以便提高效率，节省开销等。In this way, the terminal device can determine each subsequent data delivery time according to the data delivery time and the period of the data delivery time, so as to improve efficiency, save overhead, etc.
c)第二数据时刻差c) Second data time difference
由于网络设备可以获知业务的数据从核心网中的设备或应用服务器达到自身的时刻(或者说，网络设备可以获知自身接收到数据的时刻，该时刻称为“第二数据到达时刻”)，因此为了保证网络设备能够获知数据递交时刻，本申请实施例可以引入第二数据时刻差，该第二数据时刻差可以是指该第二数据到达时刻与该第二数据递交时刻之间的差值。Since the network device can know the moment when the service data reaches itself from the device or application server in the core network (or, the network device can know the moment when it receives the data, which is called the "second data arrival moment"), in order to ensure that the network device can know the data delivery moment, the embodiment of the present application can introduce a second data moment difference, which can refer to the difference between the second data arrival moment and the second data delivery moment.
这样，网络设备可以根据该第二数据到达时刻和该第二数据时刻差确定出上述所述的数据递交时刻，以便网络设备可以将数据递交时刻告知给终端设备，从而终端设备可以获知需要何时向上层递交该业务的数据，以便有利于保证后续对该业务的数据的呈现。In this way, the network device can determine the data delivery time mentioned above based on the second data arrival time and the second data time difference, so that the network device can inform the terminal device of the data delivery time, so that the terminal device can know when to submit the data of the service to the upper layer, so as to facilitate the subsequent presentation of the data of the service.
d)数据发送周期d) Data sending cycle
需要说明的是，结合上述“3)业务的数据分布特性”的“b)数据生成周期”中的内容，对于下行，应用服务器每次所生成的业务的数据，可能具有周期性。也就是说，数据生成时刻/数据发送时刻可能具有周期性。It should be noted that, in combination with the content in "b) Data generation cycle" of the above "3) Data distribution characteristics of the service", for the downlink, the service data generated by the application server each time may have periodicity. In other words, the data generation time/data sending time may have periodicity.
对此，本申请实施例引入数据发送周期，该数据发送周期可以是指核心网中的设备或应用服务器发送业务的数据的周期。In this regard, an embodiment of the present application introduces a data sending cycle, which may refer to a cycle for a device or application server in the core network to send service data.
可见，本申请实施例可以通过递交要求信息实现核心网中的设备或应用服务器来向网络设备配置/指示数据生成时刻/数据发送时刻的周期，再由网络设备根据该周期确定数据递交特性。It can be seen that the embodiments of the present application can enable the device or application server in the core network to configure/indicate the cycle of data generation time/data sending time to the network device by submitting request information, and then the network device determines the data delivery characteristics according to the cycle.
例如，网络设备可以根据该周期确定数据递交时刻、第一数据时刻差、数据递交时刻的周期等。For example, the network device may determine the data delivery time, the first data time difference, the period of the data delivery time, etc. according to the period.
③递交期望信息③Submit expected information
需要说明的是，由于不同的终端设备在支持业务的数据递交上可能具有不同的能力或者需求，因此终端设备可以向网络设备上报自身所期望的数据递交特性。It should be noted that, since different terminal devices may have different capabilities or requirements in supporting service data delivery, the terminal device may report its desired data delivery characteristics to the network device.
具体实现时，终端设备可以向网络设备发送递交期望信息，该递交期望信息可以用于指示终端设备所期望的数据递交特性。During specific implementation, the terminal device may send the delivery expectation information to the network device, and the delivery expectation information may be used to indicate the data delivery characteristics expected by the terminal device.
这样，网络设备可以根据递交期望信息看来参与到最终的数据递交特性确定过程中，再最终的数据递交特性告知给终端设备。其中，最终的数据递交特性可能不一定是终端设备所期望的数据递交特性。In this way, the network device can participate in the final data delivery characteristic determination process according to the delivery expectation information, and then inform the terminal device of the final data delivery characteristic, wherein the final data delivery characteristic may not necessarily be the data delivery characteristic expected by the terminal device.
当然，结合上述“②递交要求信息”中的内容，网络设备可以根据递交要求信息和递交期望信息确定最终的数据递交特性。Of course, in combination with the content in the above “②Submission requirement information”, the network device can determine the final data submission characteristics according to the submission requirement information and the submission expectation information.
具体的，该递交期望信息可以是根据上述的业务的数据分布特性和/或终端设备自身的能力/需求等确定。Specifically, the delivery expectation information may be determined based on the data distribution characteristics of the above-mentioned services and/or the capabilities/requirements of the terminal device itself.
7)是否递交业务的数据7) Whether to submit business data
①描述①Description
需要说明的是，虽然本申请实施例引入业务的数据递交特性，但是终端设备可能根据该数据递交特性向上层递交数据，也可能直接不向上层递交数据。下面多种实现场景进行具体说明。其中，这些实现场景之间可以相互结合以形成新的实现方式。It should be noted that although the data delivery characteristics of the service are introduced in the embodiments of the present application, the terminal device may deliver data to the upper layer according to the data delivery characteristics, or may not deliver data to the upper layer directly. The following multiple implementation scenarios are specifically described. Among them, these implementation scenarios can be combined with each other to form a new implementation method.
②具体实现场景②Specific implementation scenarios
场景1：scene 1:
a)描述a) Description
在“场景1”中，本申请实施例针对单个终端设备进行数据递交的情况。此时，终端设备在接收到业
务的数据之后向上层递交或者不向上层递交，可以是由网络设备指示的。In "Scenario 1", the present embodiment is directed to a single terminal device delivering data. Whether the service data is subsequently delivered to the upper layer or not may be instructed by the network device.
也就是说，网络设备可以指示终端设备在接收到业务的数据之后向上层递交，也可以指示终端设备在接收到业务的数据之后不向上层递交，从而实现网络指示是否递交业务的数据。That is to say, the network device can instruct the terminal device to submit the service data to the upper layer after receiving it, or can instruct the terminal device not to submit the service data to the upper layer after receiving it, thereby enabling the network to instruct whether to submit the service data.
b)显式通知或者总是通知的方式b) Explicit notification or always notify
具体的，网络设备指示，可以包括网络设备通过发送指示信息进行指示。Specifically, the network device indication may include the network device indicating by sending indication information.
其中，该指示信息可以用于指示终端设备是向上层递交，还是不向上层递交。例如，若该指示信息为“1”，则指示终端设备向上层递交；该指示信息为“0”，则指示终端设备不向上层递交；反之同理。The indication information may be used to indicate whether the terminal device submits to the upper layer or not. For example, if the indication information is "1", it indicates that the terminal device submits to the upper layer; if the indication information is "0", it indicates that the terminal device does not submit to the upper layer; and vice versa.
需要说明的是，网络设备可以通过下发指示信息来指示终端设备是否需要向上层递交，从而通过该指示信息实现显式通知或者总是通知的方式。It should be noted that the network device can instruct the terminal device whether to submit to the upper layer by sending indication information, thereby realizing explicit notification or always notifying through the indication information.
c)隐式通知的方式c) Implicit notification method
具体的，网络设备指示，可以包括网络设备在预设时间窗内通过不发送该指示信息进行指示。Specifically, the network device indication may include the network device indicating by not sending the indication information within a preset time window.
其中，该预设时间窗的结束位置在业务的数据向上层递交的时刻之前。The end position of the preset time window is before the time when the service data is submitted to the upper layer.
需要说明的是，本申请实施例引入预设时间窗，使得终端设备可以该预设时间窗中等待接收该指示信息。当网络设备在预设时间窗内不发送该指示信息时，终端设备在该预设时间窗内不会接收到该指示信息。此时，终端设备就可以知道是递交数据，还是不递交数据。It should be noted that the embodiment of the present application introduces a preset time window, so that the terminal device can wait to receive the indication information in the preset time window. When the network device does not send the indication information in the preset time window, the terminal device will not receive the indication information in the preset time window. At this time, the terminal device can know whether to submit data or not.
这样，通过引入预设时间窗，可以无法发送该指示信息就可以实现指示是否递交数据，实现隐式通知，以便节省发送该指示信息所需的开销。In this way, by introducing a preset time window, it is possible to indicate whether to submit data without sending the indication information, thereby realizing implicit notification, thereby saving the overhead required for sending the indication information.
可选的，该指示信息可以由DCI或MAC CE携带。Optionally, the indication information can be carried by DCI or MAC CE.
场景2：Scenario 2:
在“场景2”中，本申请实施例针对多个终端设备进行数据递交的情况。In "Scenario 2", the embodiment of the present application is directed to the situation where multiple terminal devices deliver data.
需要说明的是，由于有些业务可能需要确定集合内的所有终端设备同时向上层递交数据，或者集合内的所有终端设备依次向上层递交数据，如多个用户联机玩同一款游戏，因此如果集合内中存在有终端设备未正确/成功接收到该业务的数据，则集合内的所有终端设备可能不向上层递交数据。It should be noted that some services may require that all terminal devices in the set submit data to the upper layer at the same time, or that all terminal devices in the set submit data to the upper layer in turn, such as multiple users playing the same game online. Therefore, if there are terminal devices in the set that do not correctly/successfully receive the data of the service, all terminal devices in the set may not submit data to the upper layer.
例如，以第一终端设备和第二终端设备为例，若第一终端设备未成功接收业务的数据，则第二终端设备在成功接收到业务的数据之后不向上层递交。For example, taking the first terminal device and the second terminal device as an example, if the first terminal device fails to successfully receive the data of the service, the second terminal device will not submit the data to the upper layer after successfully receiving the data of the service.
场景3：Scenario 3:
a)描述a) Description
在“场景3”中，本申请实施例针对多个终端设备进行数据递交的情况。其中，该多个终端设备中的每个终端设备是否递交数据，可以是由网络设备指示的。In "Scenario 3", the embodiment of the present application is directed to a situation where multiple terminal devices deliver data, wherein whether each of the multiple terminal devices delivers data may be indicated by a network device.
b)显式通知或者总是通知的方式b) Explicit notification or always notify
具体的，网络设备可以通过指示信息单独向每个终端设备指示是否向上层递交。其中，该指示信息可以用于指示终端设备是向上层递交，还是不向上层递交。Specifically, the network device may indicate to each terminal device individually whether to submit to the upper layer through indication information. The indication information may be used to indicate whether the terminal device submits to the upper layer or not.
可选的，该指示信息可以由DCI或MAC CE携带。Optionally, the indication information can be carried by DCI or MAC CE.
可选的，该指示信息可以由终端设备的区无线网络临时标识(Cell-Radio Network Temporary Identifier，C-RNTI)小加扰，以便通过C-RNTI来区分终端设备。Optionally, the indication information may be slightly scrambled by the Cell-Radio Network Temporary Identifier (C-RNTI) of the terminal device so as to distinguish the terminal device by the C-RNTI.
具体的，网络设备可以通过广播信息同时向该多个终端设备中的每个终端设备指示是否向上层递交。Specifically, the network device may indicate to each of the multiple terminal devices at the same time through broadcast information whether to submit to the upper layer.
可选的，该广播信息可以采用一个统一的group-RNTI加扰，以便通过group-RNTI来区分不属于该多个终端设备之外的其他终端设备，该其他终端设备可能与该多个终端设备所接收的数据的业务属于不同的类型。Optionally, the broadcast information may be scrambled using a unified group-RNTI so that other terminal devices other than the multiple terminal devices can be distinguished through the group-RNTI, and the other terminal devices may be of a different type from the services of the data received by the multiple terminal devices.
c)隐式通知的方式c) Implicit notification method
具体的，网络设备可以在预设时间窗内通过不发送该指示信息的方式单独向每个终端设备指示是否向上层递交。Specifically, the network device may indicate to each terminal device individually whether to submit to the upper layer by not sending the indication information within a preset time window.
其中，该预设时间窗的结束位置在业务的数据向上层递交的时刻之前。The end position of the preset time window is before the time when the service data is submitted to the upper layer.
其中，每个终端设备可以分别对应不同的预设时间窗，可以对应同一个预设时间窗。Among them, each terminal device can correspond to a different preset time window or the same preset time window.
这样，通过引入预设时间窗，可以无法发送该指示信息就可以实现指示是否递交数据，实现隐式通知，以便节省发送该指示信息所需的开销。In this way, by introducing a preset time window, it is possible to indicate whether to submit data without sending the indication information, thereby realizing implicit notification, thereby saving the overhead required for sending the indication information.
具体的，网络设备可以在预设时间窗内通过不发送该广播信息的方式同时向该多个终端设备中的每个终端设备指示是否向上层递交。Specifically, the network device may indicate to each of the multiple terminal devices whether to submit to the upper layer by not sending the broadcast information within a preset time window.
其中，每个终端设备对应同一个预设时间窗。Among them, each terminal device corresponds to the same preset time window.
这样，通过引入预设时间窗，可以无法发送该广播信息就可以实现指示是否递交数据，实现隐式通知，以便节省发送该指示信息所需的开销。
In this way, by introducing a preset time window, it is possible to indicate whether to submit data without sending the broadcast information, thereby realizing implicit notification, thereby saving the overhead required for sending the indication information.
8)反馈已成功接收业务的数据但未向上层递交8) Feedback of successfully received service data but not submitted to the upper layer
需要说明的是，本申请实施例的终端设备可以向网络设备反馈已成功接收业务的数据但未向上层递交，以便网络设备依次做进一步决策动作，如网络设备决策终端设备是否仍然需要递交数据等。It should be noted that the terminal device of the embodiment of the present application can feedback to the network device the data of the service that has been successfully received but not submitted to the upper layer, so that the network device can make further decision actions in turn, such as the network device deciding whether the terminal device still needs to submit data.
为了便于区分和描述，本申请实施例引入第一信息，该第一信息可以用于指示终端设备已成功接收业务的数据但未向上层递交，从而通过第一信息实现反馈。For ease of distinction and description, an embodiment of the present application introduces first information, which can be used to indicate that the terminal device has successfully received the data of the service but has not submitted it to the upper layer, thereby realizing feedback through the first information.
需要说明的是，该第一信息的发送情形可以存在多种实现方式。下面进行具体说明。It should be noted that there are multiple implementations for sending the first information, which are described in detail below.
在一些可能的实现中，结合上述“7)是否递交业务的数据”中的内容，在接收业务的数据之后，若网络设备指示终端设备在接收到业务的数据之后向上层递交，则终端设备可以发送第一信息。In some possible implementations, combined with the content of “7) Whether to submit service data” above, after receiving service data, if the network device instructs the terminal device to submit to the upper layer after receiving the service data, the terminal device can send the first information.
可见，在网络设备指示自己需要向上层递交时，若终端设备因一些因素而导致未向上层递交。此时，终端设备需要通过第一信息向网络设备反馈自己未向上层递交，使得网络设备知道这个情况，以便网络设备决策后续的数据传输。It can be seen that when the network device indicates that it needs to submit to the upper layer, if the terminal device fails to submit to the upper layer due to some factors, the terminal device needs to feedback to the network device through the first information that it has not submitted to the upper layer, so that the network device knows this situation and the network device decides on subsequent data transmission.
在一些可能的实现中，在接收业务的数据之后，若终端设备决定不向上层递交，则终端设备可以发送第一信息。In some possible implementations, after receiving the data of the service, if the terminal device decides not to submit it to the upper layer, the terminal device may send the first information.
可见，终端设备可以自主决定是否向上层递交，并通过第一信息向网络设备反馈自己的决定，使得网络设备知道这个情况，以便网络设备决策后续的数据传输。It can be seen that the terminal device can independently decide whether to submit to the upper layer, and feedback its decision to the network device through the first information, so that the network device knows this situation and can decide on subsequent data transmission.
在一些可能的实现中，在接收业务的数据之后，终端设备可以发送第一信息。In some possible implementations, after receiving the data of the service, the terminal device may send the first information.
可见，不管是什么情况，终端设备都需要向网络设备反馈自身已成功接收业务的数据但未向上层递交，使得网络设备知道这个情况，以便网络设备决策后续的数据传输。It can be seen that no matter what the situation is, the terminal device needs to feedback to the network device that it has successfully received the service data but has not submitted it to the upper layer, so that the network device knows this situation and the network device can decide on subsequent data transmission.
