Description

无线通信的方法及设备Wireless communication method and device 技术领域Technical Field
本申请实施例涉及通信领域，并且更具体地，涉及一种无线通信的方法及设备。The embodiments of the present application relate to the field of communications, and more specifically, to a method and device for wireless communications.
背景技术Background technique
在新无线(New Radio，NR)***中，引入了数据集合级别的下行数据传输，每个数据集合包括多个数据包，当同一个数据集合中的一个或多个数据包无法正确传输(例如被接入网设备丢弃)的时候，这个数据集合中的剩余数据包即使被正确传输到终端设备，也无法在应用层进行正确的解码，因此这种情况下，接入网设备可能会直接将该数据集合中的剩余数据包丢弃，不再传输给终端设备。此种情况下，会导致核心网记录的下行数据传输量超过终端设备实际收到的下行数据量，从而产生不合理的计费。In the New Radio (NR) system, data set-level downlink data transmission is introduced. Each data set includes multiple data packets. When one or more data packets in the same data set cannot be transmitted correctly (for example, they are discarded by the access network device), the remaining data packets in this data set cannot be correctly decoded at the application layer even if they are correctly transmitted to the terminal device. Therefore, in this case, the access network device may directly discard the remaining data packets in the data set and no longer transmit them to the terminal device. In this case, the downlink data transmission volume recorded by the core network will exceed the downlink data volume actually received by the terminal device, resulting in unreasonable billing.

数据网络(data network，DN)可以为如IP多媒体服务(IP multi-media service，IMS)网络、互联网等为用户提供数据服务。在DN中可以有多种应用服务器(application server，AS)，提供不同的应用业务，比如运营商业务，互联网接入或者第三方业务等，AS可以实现AF实体的功能。A data network (DN) can provide data services to users, such as IP multimedia service (IMS) networks and the Internet. In a DN, there can be multiple application servers (AS) that provide different application services, such as operator services, Internet access, or third-party services. AS can implement the functions of an AF entity.
UE与应用服务器之间交互的应用层数据，例如增强现实技术(Augmented Reality，AR)/虚拟现实(virtual reality，VR)/云游戏(Cloud gaming)/视频直播等，通常是经过特定的编码、压缩之后的应用层数据。在编码过程中，可能会将媒体数据切分为多个数据集合，每个数据集合进行独立的编码，例如将一副100*100像素的图片独立编码，或者将该图片切分为10个100*10像素的图片块，对每个图片块进行独立编码。每个数据集合包括多个因特网协议(internet protocol，IP)数据包，从应用服务器发出，经由数据网络到达UPF实体，再由UPF实体发送给接入网设备，接入网设备分配无线资源将这些IP数据包通过空口发送给UE，UE收到数据之后，通过IP层以上的协议层(可以称为上层协议)，例如上层传输协议传输控制协议(Transfer Control Protocol，TCP)、用户数据包协议(User Datagram Protocol，UDP)、实时传输协议(Real-time Transport Protocol，RTP)、超文本传输协议(Hyper Text Transfer Protocol，HTTP)、或者应用层编码协议H.26x(H.263/H.264/H.265等)、动态图像专家组(Moving Picture Coding Experts Group，MPEG)、信源编码标准(Audio Video coding Standard，AVS)等识别出数据集合，对每个数据集合单独解码或者进一步进行组合，从而得到整个图片。The application layer data exchanged between UE and application server, such as augmented reality (AR)/virtual reality (VR)/cloud gaming/video live broadcast, etc., is usually the application layer data after specific encoding and compression. During the encoding process, the media data may be divided into multiple data sets, each of which is encoded independently, for example, a 100*100 pixel picture is encoded independently, or the picture is divided into 10 100*10 pixel picture blocks, and each picture block is encoded independently. Each data set includes multiple Internet protocol (IP) data packets, which are sent from the application server, reach the UPF entity via the data network, and then are sent to the access network device by the UPF entity. The access network device allocates wireless resources to send these IP data packets to the UE through the air interface. After receiving the data, the UE identifies the data set through the protocol layer above the IP layer (which can be called the upper layer protocol), such as the upper layer transmission protocol Transmission Control Protocol (Transfer Control Protocol, TCP), User Datagram Protocol (User Datagram Protocol, UDP), Real-time Transport Protocol (Real-time Transport Protocol, RTP), Hypertext Transfer Protocol (Hyper Text Transfer Protocol, HTTP), or application layer coding protocol H.26x (H.263/H.264/H.265, etc.), Moving Picture Coding Experts Group (Moving Picture Coding Experts Group, MPEG), Audio Video Coding Standard (Audio Video Coding Standard, AVS), etc., and decodes each data set separately or further combines them to obtain the entire picture.
在5G***中，SMF实体从UPF实体收集数据传输报告(也称为使用信息，或网络资源使用信息、数据使用信息等)，数据传输报告例如数据传输量、数据传输量到达特定门限的事件等，SMF 实体根据从UPF实体收集到的数据传输报告可以与计费***进行交互，从而根据终端的数据使用情况对终端进行计费。In the 5G system, the SMF entity collects data transmission reports (also called usage information, or network resource usage information, data usage information, etc.) from the UPF entity. The data transmission reports include data transmission volume, events when the data transmission volume reaches a specific threshold, etc. The SMF entity can interact with the billing system based on the data transmission reports collected from the UPF entity, thereby charging the terminal according to the terminal's data usage.
为便于理解本申请实施例的技术方案，以下对本申请所解决的问题进行说明。To facilitate understanding of the technical solutions of the embodiments of the present application, the problems solved by the present application are described below.
5G网络中对每个数据包独立传输，也就是数据包之间没有依赖关系。在后续的演进中考虑支持数据集合级别的数据传输，每个数据集合包括多个数据包，当同一个数据集合中的一个或多个数据包无法正确传输(例如被接入网设备丢弃)的时候，这个数据集合中的剩余数据包即使被正确传输到终端，也无法在应用层进行正确的解码，因此这种情况下，接入网设备可能会直接将该数据集合中的剩余数据包丢弃，不再传输给UE(也即，丢弃整个数据集合)。因为数据传输报告是UPF实体提供给SMF实体的，对于下行数据，UPF实体统计的数据传输量会包括被接入网设备丢弃的数据，造成对UE的数据使用量的统计超过UE实际收到的数据量，计费超出UE的实际使用量，造成用户对运营商网络计费的不满。In the 5G network, each data packet is transmitted independently, that is, there is no dependency between data packets. In the subsequent evolution, support for data transmission at the data set level is considered. Each data set includes multiple data packets. When one or more data packets in the same data set cannot be transmitted correctly (for example, they are discarded by the access network device), the remaining data packets in this data set cannot be correctly decoded at the application layer even if they are correctly transmitted to the terminal. Therefore, in this case, the access network device may directly discard the remaining data packets in the data set and no longer transmit them to the UE (that is, discard the entire data set). Because the data transmission report is provided by the UPF entity to the SMF entity, for downlink data, the data transmission volume counted by the UPF entity will include data discarded by the access network device, causing the statistics of the UE's data usage to exceed the actual data volume received by the UE, and the billing exceeds the actual usage of the UE, causing users to be dissatisfied with the operator's network billing.
基于上述问题，本申请提出了一种下行数据传输的方案，核心网网元可以基于被丢弃的数据集合的信息和/或成功传输的数据集合的信息确定实际传输的下行数据量，避免了因核心网记录的下行数据传输量超过终端设备实际收到的下行数据量而导致的不合理计费，提升了用户体验。Based on the above problems, the present application proposes a solution for downlink data transmission, in which the core network network element can determine the actual amount of downlink data transmitted based on the information of the discarded data set and/or the information of the successfully transmitted data set, thereby avoiding unreasonable billing caused by the downlink data transmission volume recorded by the core network exceeding the downlink data volume actually received by the terminal device, thereby improving the user experience.

在本申请实施例中，一个数据集合包括多个数据包，其中，数据包中的数据为下行数据。需要说明的是，当一个数据集合中的一个或多个数据包无法正确传输(例如被接入网设备丢弃)的时候，该数据集合中数据包无法在应用层进行正确的解码，因此接入网设备可以丢弃该数据集合。In the embodiment of the present application, a data set includes multiple data packets, wherein the data in the data packets are downlink data. It should be noted that when one or more data packets in a data set cannot be correctly transmitted (for example, discarded by an access network device), the data packets in the data set cannot be correctly decoded at the application layer, so the access network device can discard the data set.
在本申请实施例中，第一网元(核心网网元)可以从第二网元获取被丢弃的数据集合的信息和/或成功传输的数据集合的信息，从而第一网元可以基于被丢弃的数据集合的信息和/或成功传输的数据集合的信息确定实际传输的下行数据量，避免了因核心网记录的下行数据传输量超过终端设备实际收到的下行数据量而导致的不合理计费，提升了用户体验。In an embodiment of the present application, the first network element (core network element) can obtain information about a discarded data set and/or information about a successfully transmitted data set from the second network element, so that the first network element can determine the actual amount of downlink data transmitted based on the information about the discarded data set and/or information about the successfully transmitted data set, thereby avoiding unreasonable billing caused by the downlink data transmission volume recorded by the core network exceeding the downlink data volume actually received by the terminal device, thereby improving user experience.
在本申请实施例中，接入网设备将数据集合中的无效数据包丢弃，造成了对UE的数据使用量的统计超过UE实际收到的数据量，本申请实施例可以对终端使用的数据进行更准确的计费，提高用户满意度。In an embodiment of the present application, the access network device discards invalid data packets in the data set, causing the statistics of the UE's data usage to exceed the amount of data actually received by the UE.
