技术领域Technical field
本发明实施例涉及无线通信技术领域，并且更具体地，涉及信息处理的方法、终端和网络侧设备。Embodiments of the present invention relate to the field of wireless communication technologies, and, more particularly, to a method, a terminal, and a network side device for information processing.
背景技术Background technique
第三代合作伙伴计划(The 3rd Generation Partnership Project，3GPP)组织制定的通用移动通信***(Universal Mobile Telecommunications System，UMTS)的演进，长期演进(Long Term Evolution，LTE)***，并持续研究新一代通信***。The evolution of the Universal Mobile Telecommunications System (UMTS) developed by the 3rd Generation Partnership Project (3GPP), Long Term Evolution (LTE) system, and continuous research on next-generation communications system.
一般的通信***至少包括核心网元和接入网网元。如LTE***中的演进分组核心网(Evolved Packet Core，EPC)和演进Node B(Evolved Node B，eNode B)。EPC负责核心网部分，其信令处理部分为移动管理实体(Mobility Management Entity，MME)，数据处理部分为服务网管(Serving Gateway，S-GW)，而eNode B负责接入网部分，也称演进的UTRAN(Evolved UTRAN，E-UTRAN)。A general communication system includes at least a core network element and an access network element. For example, an Evolved Packet Core (EPC) and an Evolved Node B (eNode B) in an LTE system. The EPC is responsible for the core network part. The signaling processing part is the Mobility Management Entity (MME), the data processing part is the Serving Gateway (S-GW), and the eNode B is responsible for the access network part, also called evolution. UTRAN (Evolved UTRAN, E-UTRAN).
在通信***的演进过程中小区的数目，以及小区中终端的数目会在较大的范围内变化。举例而言，某个小区可能会变得很大，则该小区内的终端数目会变得很多。而作为一种相反的情况，某个小区可能会变得很小，该小区内的终端数目会变得很少，而在一定范围内的小区数量会非常多。一种新的方案被提出来满足这种多变的需求。即基站标识符ID的长度不是固定的，而是根据配置场景的变化进行调整的。即基站ID的长度不再是固定长度，而是取值于一个范围。比如22-32bits。The number of cells in the evolution of the communication system, as well as the number of terminals in the cell, will vary over a large range. For example, if a certain cell may become very large, the number of terminals in the cell may become large. As an opposite case, a certain cell may become small, the number of terminals in the cell may become small, and the number of cells within a certain range may be very large. A new approach has been proposed to meet this changing need. That is, the length of the base station identifier ID is not fixed, but is adjusted according to changes in the configuration scenario. That is, the length of the base station ID is no longer a fixed length, but takes a value. For example, 22-32bits.
但是可变长度的基站ID带来另一个新的问题，即通信对方不清楚如何识别，进而处理该变长的基站ID，造成通信的混乱。现有方案中，没有方案来支持可变长的基站ID。However, the variable length base station ID brings another new problem, that is, the communication partner does not know how to recognize, and thus processes the variable base station ID, causing communication confusion. In the existing scheme, there is no scheme to support a variable length base station ID.

The technical solutions provided by the embodiments of the present invention are equally applicable to similar technical problems, as the network architecture evolves and new service scenarios arise.
终端(terminal device)，也可以称之为用户设备(User Equipment，UE)、移动终端(Mobile Terminal，MT)、移动用户设备等，可以经无线接入网(例如，Radio Access Network，RAN)与一个或多个核心网进行通信。用户设备可以是移动终端，如移动电话(或称为“蜂窝”电话)和具有移动能力的计算机，例如，可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置。也可以是机器类通信MTC中的通信设备。A terminal device, which may also be called a user equipment (User Equipment, UE), a mobile terminal (MT), a mobile user equipment, etc., may be connected to a radio access network (for example, a Radio Access Network, RAN). One or more core networks communicate. The user equipment may be a mobile terminal, such as a mobile telephone (or "cellular" telephone) and a mobile capable computer, for example, a portable, pocket, handheld, computer built-in or in-vehicle mobile device. It can also be a communication device in a machine type communication MTC.
网络设备可以是一种部署在无线接入网中为终端提供无线通信功能的装置。所述网络可以包括各种形式的宏基站，微基站(也称为小站)，中继站，接入点等，也可以包括各种形式的控制节点，如网络控制器。所述控制节点可以连接多个基站，并为所述多个基站覆盖下的多个终端配置资源。在采用不同的无线接入技术的***中，具备基站功能的设备的名称可能会有所不同，如LTE中的eNB或e-NodeB，也可以是5G或NR中的基站或发射接收端点，如gNB，本发明并不限定。A network device can be a device deployed in a wireless access network to provide wireless communication functionality to a terminal. The network may include various forms of macro base stations, micro base stations (also referred to as small stations), relay stations, access points, etc., and may also include various forms of control nodes, such as network controllers. The control node may connect multiple base stations and allocate resources for multiple terminals covered by the multiple base stations. In systems using different radio access technologies, the names of devices with base station functions may be different, such as eNBs or e-NodeBs in LTE, or base stations or transmitting and receiving endpoints in 5G or NR, such as gNB, the invention is not limited.
需要说明的是，图1所示的通信***100中所包含的终端的数量和类型仅仅是一种例举，本发明实施例也并不限制于此。譬如，还可以包括更多与基站进行通信的蜂窝终端，或者包括更多进行设备到设备D2D通信的D2D终端，为简明描述，不在附图中一一描述。此外，所述通信***100可以并不限于包括所述基站和终端，譬如还可以包括核心网设备或用于承载虚拟化网络功能的设备等，这些对于本领域普通技术人员而言是显而易见的，在此不一一详述。It should be noted that the number and types of terminals included in the communication system 100 shown in FIG. 1 are merely exemplary, and the embodiments of the present invention are not limited thereto. For example, it may also include more cellular terminals that communicate with the base station, or more D2D terminals that perform device-to-device D2D communication, which are not described in the drawings for the sake of brevity. Moreover, the communication system 100 may not be limited to include the base station and terminal, and may also include a core network device or a device for carrying virtualized network functions, etc., as will be apparent to those of ordinary skill in the art. Not detailed here.
应用上述网络架构，当终端发起通信业务进行数据的发送时，需要先建立与网络侧的无线资源控制(Radio Resource Control，RRC)连接，进而发起到接入网的连接和发起到核心网的连接，使得终端进入连接态，进而再建立数据承载进行数据发送。其中，在终端处于连接态期间，如果终端发生移动可能进行小区切换。当终端没有数据传输时，可以执行RRC连接释放过程，使得UE返回到空闲态。在技术演进过程中相对于上述的空闲态和连接态，一种新的状态被提出。专利文本WO2016/123809提出了中间态的概念。即网络侧设备发送的配置信息中包括一列表，所述列表为小区列表或基站列表；该列表用于指示终端 如果发生移动，且是在列表范围内移动时，所述终端可自行进行小区重选，而不需要通知网络侧设备。所述终端一旦需要发送数据或者移动超出了管理区域，需要通知所述网络侧设备。可以理解的，至少在上述空闲态或中间态时，终端处于一种不能直接发送信令或者数据的状态。终端如果需要发送数据需要向基站发起连接恢复请求。本申请中将这种状态称为非激活(inactive)态，包括而不限于如下名称：非活动状态、中间态、空闲态、轻连接状态、非活动态、低活动态、寻呼态或者低开销状态。When the terminal initiates a communication service to transmit data, the terminal needs to establish a radio resource control (RRC) connection with the network side, and then initiate a connection to the access network and initiate a connection to the core network. So that the terminal enters the connected state, and then establishes a data bearer for data transmission. Wherein, during the connection state of the terminal, cell handover may be performed if the terminal moves. When the terminal has no data transmission, an RRC connection release procedure may be performed, so that the UE returns to the idle state. A new state is proposed in the process of technological evolution relative to the idle state and the connected state described above. The patent text WO2016/123809 proposes the concept of an intermediate state. That is, the configuration information sent by the network side device includes a list, where the list is a cell list or a base station list; the list is used to indicate that if the terminal moves and moves within the list, the terminal may perform cell weight by itself. Select, without having to notify the network side device. The terminal needs to notify the network side device once it needs to send data or move beyond the management area. It can be understood that, at least in the above idle state or intermediate state, the terminal is in a state in which signaling or data cannot be directly transmitted. If the terminal needs to send data, it needs to initiate a connection recovery request to the base station. This state is referred to as an inactive state in the present application, including but not limited to the following names: inactive state, intermediate state, idle state, light connection state, inactive state, low activity state, paging state, or low Overhead status.
处于非激活状态的终端需要在网络侧设备中保存有上下文信息，以方便恢复连接等场景的需求。特别是终端需要向新的基站恢复连接时，新的基站需要从该终端所归属的旧基站获取该终端的上下文信息。恢复连接过程可以是因为如下原因：A terminal that is in an inactive state needs to store context information on the network side device to facilitate the recovery of the connection and other scenarios. In particular, when the terminal needs to restore the connection to the new base station, the new base station needs to obtain the context information of the terminal from the old base station to which the terminal belongs. The recovery process can be due to the following reasons:
1)终端有数据或者信令需要传输；1) The terminal has data or signaling to be transmitted;
2)终端需要发送管理区域更新(包括周期性的更新，因为移出位置管理区而更新)；2) The terminal needs to send a management area update (including periodic updates, which are updated because they are moved out of the location management area);
3)终端收到寻呼消息；3) The terminal receives the paging message;
4)其他原因。4) Other reasons.
用于标识终端的上下文的标识符可以被称作上下文标识符，UE context ID，也可以被称为恢复标识符，也叫resume ID。该恢复标识符通常包括基站标识符(基站ID)和终端标识符(终端ID)。图3示出一种实现方式。终端上下文标识符共40bit，前20bit包含基站ID，后20bit终端ID。收到该恢复标识符的网络设备可以根据所述基站ID来确定该终端所在的基站，根据该终端ID来确定是哪个终端，进而可以确定该终端的上下文信息，从而获取该上下文信息。所述上下文信息包括而不限于：终端的无线承载的配置信息，安全信息，能力信息，或者物理资源信息中一种或者多种。The identifier used to identify the context of the terminal may be referred to as a context identifier, and the UE context ID may also be referred to as a recovery identifier, also known as a resume ID. The recovery identifier typically includes a base station identifier (base station ID) and a terminal identifier (terminal ID). Figure 3 illustrates an implementation. The terminal context identifier is 40 bits in total, and the first 20 bits include the base station ID and the last 20 bit terminal ID. The network device that receives the recovery identifier may determine the base station where the terminal is located according to the base station ID, determine which terminal is based on the terminal ID, and further determine context information of the terminal, thereby acquiring the context information. The context information includes, but is not limited to, one or more of configuration information, security information, capability information, or physical resource information of a radio bearer of the terminal.
需要理解，为了行文方便，本文各个实施例中仅用基站ID或者终端ID用来举例。基站ID可以为网络设备的ID，而不限于一定是基站本身的。终端ID可以为通信设备的ID，而不限于一定是终端的。It should be understood that, for convenience of the text, only the base station ID or the terminal ID is used as an example in the various embodiments herein. The base station ID may be the ID of the network device, and is not necessarily limited to the base station itself. The terminal ID may be the ID of the communication device, and is not necessarily limited to the terminal.
新的场景中，基站ID的长度不再是20bit，而是一个范围。具体的，基站ID的长度可以是22bit，或者23bit，或者32bit。如果在对应的终端上下文标识符还维持原有的方式的话，是无法知晓哪一部分是基站ID哪一部分是终端ID的。这就使得通信对方无法通过该标识符来完成通信功能。In the new scenario, the length of the base station ID is no longer 20 bits, but a range. Specifically, the length of the base station ID may be 22 bits, or 23 bits, or 32 bits. If the original terminal context identifier is still maintained in the original mode, it is impossible to know which part is the base station ID and which part is the terminal ID. This makes it impossible for the communication partner to complete the communication function by the identifier.
为了解决上述问题，本申请提供多种新的信令方法和设备，来优化通信功能。In order to solve the above problems, the present application provides various new signaling methods and devices to optimize communication functions.
截短的IDTruncated ID
可以采用截短的context ID。即将可变长的基站ID长度截短，而符合原有的通信要求。具体的，可以只截短基站ID，或者可以只截短终端ID，或者也可以同时截短基站ID和终端ID。A truncated context ID can be used. The variable length base station ID length is shortened to meet the original communication requirements. Specifically, only the base station ID may be truncated, or only the terminal ID may be truncated, or the base station ID and the terminal ID may be simultaneously truncated.
图2示出实施例一：Figure 2 shows the first embodiment:
201，第一网络设备向终端发送第一上下文标识符，该第一上下文标识符包括第一网络设备的标识符和所述终端的标识符；201. The first network device sends a first context identifier to the terminal, where the first context identifier includes an identifier of the first network device and an identifier of the terminal.
203，终端向第二网络设备发送请求消息，所述请求消息包括第二上下文标识符，所述第二上下文标识符包括所述第一网络设备标识符的一部分和所述设备标识符的一部分。这里第二上下文标识符是截短后的第一上下文标识符。203. The terminal sends a request message to the second network device, where the request message includes a second context identifier, where the second context identifier includes a portion of the first network device identifier and a portion of the device identifier. Here the second context identifier is the truncated first context identifier.
通过上下文标识符中携带的信息，使得通信双方可以识别出对应的信息，避免了通信的混乱。进一步的，因为所述第二上下文标识符包括了完整的标识符的一部分，并不需要将全部第一上下文标识符发送出去，所以节省了信令开销。Through the information carried in the context identifier, the communication parties can identify the corresponding information and avoid communication confusion. Further, since the second context identifier includes a part of the complete identifier and does not need to transmit all of the first context identifiers, signaling overhead is saved.
为了行文方便，本文将包含了所述第一网络设备标识符的一部分或所述设备标识符的一部分的上下文标识符统称为截短的上下文标识符，将包含了完整的第一网络设备的标识符和完整的所述终端的标识符统称为完整的上下文标识符。这里并不限定是第一还是第二。在图4中可以看出截短的第二上下文标识符比完整的第一上下文标识符短。For convenience of writing, a context identifier including a part of the first network device identifier or a part of the device identifier is collectively referred to as a truncated context identifier, which will contain the identity of the complete first network device. The identifiers of the complete and the terminal are collectively referred to as the complete context identifier. It is not limited to the first or the second here. It can be seen in Figure 4 that the truncated second context identifier is shorter than the complete first context identifier.
终端可以根据网络的配置规则来截短第一上下文标识符，也可以根据通信双方的约定来截短。通常，截短使用完整ID中多个比特的低位比特，包括最低有效位(least significant bit,LSB)。LSB相对的是最高有效位(most significant bit，MSB)。以图3所示的上下文标识符中，通常MSB在LSB的左边。但是本文不排斥MSB在LSB右边的情况。The terminal may truncate the first context identifier according to the configuration rule of the network, or may be shortened according to the agreement of the communication parties. Typically, truncation uses the lower bits of multiple bits in the full ID, including the least significant bit (LSB). The LSB is the most significant bit (MSB). In the context identifier shown in Figure 3, usually the MSB is to the left of the LSB. However, this article does not exclude the MSB from the right side of the LSB.
作为可替换的例子，所述第二上下文标识符可以包括所述第一网络设备标识符的一部分和所述设备标识符；或者可以包括所述第一网络设备标识符和所述设备标识符的一部分。As an alternative example, the second context identifier may include a portion of the first network device identifier and the device identifier; or may include the first network device identifier and the device identifier portion.
在图2的方案中，通信的另一方，如第二网络设备，根据完整的第二上下文标识符或者截短的第二上下文标识符，可以知晓该标识符所指示的网络设备和终端。很容易理解完整的第二上下文标识符指示了具体的网络设备和该网络设备中的具体终端。In the scenario of FIG. 2, the other party to the communication, such as the second network device, may be aware of the network device and terminal indicated by the identifier based on the complete second context identifier or the truncated second context identifier. It is easy to understand that a complete second context identifier indicates a particular network device and a particular terminal in the network device.
对于截短的上下文标识符而言，情况稍微复杂一点。在二进制计数方法中，低位向高位进位。因而，标识符中高位变化幅度较少，或者完全一致的概率较高。相反，低位变化幅度较大，重合的可能性较低。因为高位不变化，所以只比较低位，可以同样达到区别不同设备的目的。第二网络设备可以比较截短的基站ID与已知的基站ID的多个低位比特，便可以知晓截短的基站ID所指示的具体网络设备。同理终端ID也是类似的。因为截短的上下文通过低位比特依旧可以实现识别的功能，所以在节省信令的基础上，进一步提供了鲁棒性。For a truncated context identifier, the situation is a bit more complicated. In the binary counting method, the low bit is carried to the upper bit. Thus, the probability of a high level change in the identifier is small, or the probability of being completely consistent is high. On the contrary, the low position changes more and the probability of coincidence is lower. Because the high position does not change, so only the lower level, can also achieve the purpose of distinguishing different devices. The second network device can compare the truncated base station ID with a plurality of lower bits of the known base station ID to know the specific network device indicated by the truncated base station ID. The same terminal ID is similar. Since the truncated context can still implement the identification function through the lower bits, the robustness is further provided on the basis of saving signaling.
在一个例子中，可以截取第一上下文标识符中网络设备标识符的低位的M比特，作为第二上下文标识符中的网络设备标识符，M为自然数。也可以截取第一上下文标识符中终端的标识符的低位的N比特作为第二上下文标识符中的终端的标识符，N为自然数。In one example, the lower M bits of the network device identifier in the first context identifier may be intercepted as the network device identifier in the second context identifier, M being a natural number. It is also possible to intercept the lower N bits of the identifier of the terminal in the first context identifier as the identifier of the terminal in the second context identifier, N being a natural number.
第一上下文标识符的可能取值举例如下：Examples of possible values for the first context identifier are as follows:
场景编号Scene number 总长Total length 基站IDBase station ID 终端IDTerminal ID
11 4848 3232 1616
22 4848 22twenty two 2626
33 5252 3232 2020
44 5252 22twenty two 3636
M,N的长度确定可以为预定的值，比如M＝N＝12。或者M，N长度可变，比如令P＝M+N或者P＝M/N,所述P为常数。或者网络设备发送上述配置信息指示P的取值给所述终端。在应用场景中，M、N的取值受到通信***的限制，是有一定的范围的。比如，M：N＝2:1，则截断时，基站ID截断长度为UE ID截断长度的2倍，比如基站ID截断后为20比特，UE  ID截断后为10比特。The length of M, N can be determined to be a predetermined value, such as M = N = 12. Or M, N is variable in length, such as let P = M + N or P = M / N, the P is a constant. Or the network device sends the configuration information indication P to the terminal. In the application scenario, the values of M and N are limited by the communication system, and there is a certain range. For example, if M:N=2:1, the truncation length of the base station ID is twice the length of the UE ID truncation, for example, the base station ID is truncated to 20 bits, and the UE ID is truncated to 10 bits.
当P为一个相对固定值时，M和N的关系相对恒定。当P＝M+N为常数时，第二标识符的总长度为P。当P＝M/N时，网络标识符和终端标识符在第二上下文标识符中的位置被确定。则通信对方可以根据已知信息不再通知这些标识符的关系，从而节省信令。When P is a relatively fixed value, the relationship between M and N is relatively constant. When P = M + N is a constant, the total length of the second identifier is P. When P = M / N, the location of the network identifier and the terminal identifier in the second context identifier is determined. Then, the communication partner can no longer notify the relationship of these identifiers based on the known information, thereby saving signaling.
作为一种变形，第一网络设备可以a)向终端发送完整的第一上下文标识符，或者b)向终端发送截短的第一上下文标识符，或者c)向终端即发送完整的第一上下文标识符也发送截短的第一上下文标识符。方案a)将完整的ID信息传递给了终端，保证了终端处理的灵活性；方案b)可以与受限的***兼容，而不需要更多的调整，节省了信令。可选的，通信双方可以通过配置信息传递截短的第一上下文标识符，以及所需的其他信息，比如P、M、N的数值。方案c)中，完整的第一上下文标识符和截短的第一上下文标识符可以分开通过多条配置消息发送或者用一条配置消息一起发送。所述配置消息是可以由以下消息之一或者多个携带：RRC连接释放消息、RRC连接挂起消息、RRC连接重配置消息、RRC连接建立消息、或者RRC连接重配置消息、***广播信息、专有信令消息。As a variant, the first network device may a) send the complete first context identifier to the terminal, or b) send the truncated first context identifier to the terminal, or c) send the complete first context to the terminal The identifier also sends a truncated first context identifier. Solution a) Passing the complete ID information to the terminal ensures the flexibility of the terminal processing; the solution b) can be compatible with the limited system without requiring more adjustments, saving signaling. Optionally, the communicating parties can transmit the truncated first context identifier and other required information, such as values of P, M, and N, through the configuration information. In scheme c), the complete first context identifier and the truncated first context identifier may be sent separately through multiple configuration messages or together with a configuration message. The configuration message may be carried by one or more of the following messages: an RRC connection release message, an RRC connection suspension message, an RRC connection reconfiguration message, an RRC connection setup message, or an RRC connection reconfiguration message, system broadcast information, There are signaling messages.
可选的，在图2的方案中，终端可以获得完整的或者截短的第一上下文标识符。当其不能知晓第二网络设备是否请求截短的上下文标识符时，在发送第二上下文标识符之前需要知晓所述第二网络设备允许发送的上下文标识符的长度信息(截断上下文或者完整上下文)。图2中，202，第二网络设备发送通知给终端。终端可以通过第二网络设备发来的通知，确定使用截短的上下文标识符与其通信，或者确定使用完整的上下文标识符与其通信。这取决于第二网络设备是否允许发送截短的上下文标识符。通过上述通知，第二网络设备可以控制终端发送的上下文标识符的长度选择，进而提供了更好的兼容性，否则终端的功能不能充分被调度。Optionally, in the solution of FIG. 2, the terminal may obtain a complete or truncated first context identifier. When it is unable to know whether the second network device requests a truncated context identifier, it is necessary to know the length information (truncated context or complete context) of the context identifier that the second network device is allowed to transmit before transmitting the second context identifier. . In FIG. 2, 202, the second network device sends a notification to the terminal. The terminal may determine to communicate with the truncated context identifier via the notification sent by the second network device, or determine to communicate with the full context identifier. This depends on whether the second network device is allowed to send a truncated context identifier. Through the above notification, the second network device can control the length selection of the context identifier sent by the terminal, thereby providing better compatibility, otherwise the function of the terminal cannot be fully scheduled.
具体的，所述终端根据从第二网络设备的通知确定使用截短的还是完整的第二上下文标识符。所述通知可以通过***广播或者网络发送的授权信息来承载。或者，所述通知为隐式的方式，比如终端根据第二网络设备的广播确定第二网络设备的网络类型确定使用截断的上下文标识符，而不需要专门发送通知本身。比如当终端的第一网络设备为5G的网络设备gNB时，在第二网络设备为LTE网络的eNB时终端就使用截断的上下文标识。Specifically, the terminal determines whether to use the truncated or complete second context identifier according to the notification from the second network device. The notification may be carried by system broadcast or authorization information sent by the network. Alternatively, the notification is an implicit manner, for example, the terminal determines, according to the broadcast of the second network device, that the network type of the second network device determines to use the truncated context identifier, without specifically sending the notification itself. For example, when the first network device of the terminal is the 5G network device gNB, the terminal uses the truncated context identifier when the second network device is the eNB of the LTE network.
例如：所述指示信息指示允许终端使用截短的第二上下文标识符。如果收到所述指示，则使用截短的第二上下文标识符，否则使用完整的第二上下文标识符。For example: the indication information indicates that the terminal is allowed to use the truncated second context identifier. If the indication is received, a truncated second context identifier is used, otherwise the full second context identifier is used.
又例如：所述终端根据所述授权信息(例如UL grant消息所携带的信息)确定终端可以发送的消息大小。如果可以容纳完整的第二上下文标识符，则发送所述完整的第二上下文标识符，否则发送截短的第二上下文标识符。For another example, the terminal determines, according to the authorization information (for example, the information carried by the UL grant message), the size of the message that the terminal can send. The complete second context identifier is sent if the complete second context identifier can be accommodated, otherwise the truncated second context identifier is sent.
高位和低位High and low
传统上，如图3所示，在上下文标识符中，基站ID和终端ID顺次连接，基站ID的低位与终端ID的高位相连。这样在图2的方案中，终端收到的完整的或者截短的第一上下文标识符中，都需要知晓终端ID的起始位置，也就是MSB的位置，或者基站ID的终止位置，也就是LSB的位置，或者基站ID的长度信息，或者终端ID的长度信息。否则，终端不能从所述第一上下文标识符中区分出所需的字节，进而造成通信的混乱。Conventionally, as shown in FIG. 3, in the context identifier, the base station ID and the terminal ID are sequentially connected, and the lower bits of the base station ID are connected to the upper bits of the terminal ID. Thus, in the scheme of FIG. 2, in the complete or truncated first context identifier received by the terminal, it is necessary to know the starting position of the terminal ID, that is, the location of the MSB, or the termination position of the base station ID, that is, The location of the LSB, or the length information of the base station ID, or the length information of the terminal ID. Otherwise, the terminal cannot distinguish the required bytes from the first context identifier, thereby causing confusion in communication.
如图5所示，以第一上下文标识符为例，基站ID的LSB在最左边，MSB在基站ID部分的最右边，高位在右，低位在左。而终端ID依然保留图2的排列方式。本文中为了表达方便，第一上下标识符的最左端比特称作第一上下文标识符的最高有效位(MSB)，第一上下的最右端比特称作第一上下文标识符的最低有效位(LSB)，因此对于第一上下文标识符本身而言，其高位依旧在左边，低位在右边。换句话说，第一上下文标识符的MSB和基站ID的LSB是相同的位。对应的第二上下文标识符也可以采取这种设置方式。As shown in FIG. 5, taking the first context identifier as an example, the LSB of the base station ID is on the far left, the MSB is on the far right of the base station ID part, the high bit is on the right, and the low bit is on the left. The terminal ID still retains the arrangement of Figure 2. For convenience of expression, the leftmost bit of the first upper and lower identifier is referred to as the most significant bit (MSB) of the first context identifier, and the rightmost bit of the first upper and lower bits is referred to as the least significant bit of the first context identifier (LSB) Therefore, for the first context identifier itself, its high position is still on the left and the low is on the right. In other words, the MSB of the first context identifier and the LSB of the base station ID are the same bits. The corresponding second context identifier can also take this setting.
该方案中，基站ID和终端ID的低位都是从上下文标识符的两端开始的，接收设备，如图2中的终端，可以从低位截取所需长度的ID，而不用关心该标识符到底在哪里终止。比如，假定第一上下文标识符长度为L bit，需要截取的基站ID部分为M比特，需要截取终端ID部分为N比特，则终端可以从第一上下文的第一比特到第M比特部分获取基站ID截取部分。可以从第一上下文的第L-N+1比特到第L比特获取终端ID的长度。其中L，M，N为自然数。作为举例，L>N。这样就提供了一种盲检测的能力，从而节省了信令开销。另外，通信双方也可以依据约定或者配置消息或者通知来知晓上述高位和低位方案。如第一网络设备可以通过配置信息中的字段或者隐式通知来告知终端，所述第一上下文标识符采用了图5中的格式。In this solution, the lower bits of the base station ID and the terminal ID start from both ends of the context identifier, and the receiving device, such as the terminal in FIG. 2, can intercept the ID of the required length from the low bit without concern for the identifier. Where to terminate. For example, if the length of the first context identifier is L bit, the part of the base station ID that needs to be intercepted is M bits, and the part of the terminal ID needs to be intercepted to be N bits, the terminal can acquire the base station from the first bit to the Mth bit of the first context. ID interception section. The length of the terminal ID can be obtained from the L-N+1th bit to the Lth bit of the first context. Where L, M, and N are natural numbers. As an example, L>N. This provides a blind detection capability, which saves signaling overhead. In addition, the communicating parties can also know the above high and low solutions according to the appointment or configuration message or notification. The first network device may inform the terminal by a field in the configuration information or an implicit notification, the first context identifier adopting the format in FIG.
举例而言，若***规定，基站ID的范围是22-32比特，则只需要截取22或者更少比特的基站ID，就可以确保截取的基站ID而不会包含其他不需要的信息(如终端ID)。通过截取后的基站ID与已知基站ID的对应低位的相同或者基本相同，可以识别出该ID对应的基站。类似的，也可以识别出对应的终端。For example, if the system specifies that the range of the base station ID is 22-32 bits, only the base station ID of 22 or less bits needs to be intercepted, so that the intercepted base station ID can be ensured without including other unnecessary information (such as a terminal). ID). The base station corresponding to the ID can be identified by the intercepted base station ID being the same as or substantially the same as the corresponding lower bit of the known base station ID. Similarly, the corresponding terminal can also be identified.
作为一种变形，终端ID可以在基站ID的左边，只要采取低位在上下文标识符的两端方案，也能实现相同的技术效果。As a variant, the terminal ID can be on the left side of the base station ID, and the same technical effect can be achieved as long as the lower order is adopted at both ends of the context identifier.
可选的，终端在将基站ID的多个低位比特进行截取后，将截取后的比特的高低位进行反转，将反转后的比特和截取的终端ID低位比特进行串接发送给网络设备。反转后的基站ID与基站ID的部分低比特位相对应。或者，终端在将终端ID的多个低位比特进行截取后，将截取后的比特的高低位进行反转，将反转后的比特和截取的基站ID低位比特进行串接发送给网络设备。反转后的终端ID与终端ID的部分低比特位相对应。Optionally, after intercepting the plurality of low-order bits of the base station ID, the terminal inverts the high and low bits of the truncated bit, and serially transmits the inverted bit and the intercepted terminal ID low-order bit to the network device. . The inverted base station ID corresponds to a part of the low bit of the base station ID. Alternatively, after intercepting the plurality of lower bits of the terminal ID, the terminal inverts the high and low bits of the truncated bit, and serially transmits the inverted bit and the intercepted base station ID low bit to the network device. The inverted terminal ID corresponds to a part of the low bit of the terminal ID.
实施例二可以基于实施例一的方法，只是其中的第一上下文标识符或者第二上下文标识符遵循了图5的规则，具体过程不再赘述。该实施例可以包括如下情形中的一种：The second embodiment can be based on the method of the first embodiment, except that the first context identifier or the second context identifier follows the rules of FIG. 5, and details are not described herein again. This embodiment may include one of the following situations:
所述第一网络设备标识符的一部分中的最低有效位LSB位于所述第二上下文标识符的最高有效位MSB或最低有效位LSB；和/或The least significant bit LSB of a portion of the first network device identifier is located at a most significant bit MSB or a least significant bit LSB of the second context identifier; and/or
所述终端标识符的一部分中的最低有效位LSB位于所述第二上下文标识符的最高有效位MSB或最低有效位LSB；和/或The least significant bit LSB of a portion of the terminal identifier is located at the most significant bit MSB or least significant bit LSB of the second context identifier; and/or
所述第一网络设备标识符的最低有效位LSB位于所述第一上下文标识符的最高有效位MSB或最低有效位LSB；和/或The least significant bit LSB of the first network device identifier is located at a most significant bit MSB or a least significant bit LSB of the first context identifier; and/or
所述终端标识符的最低有效位LSB位于所述第一上下文标识符的最高有效位MSB或最低有效位LSB。The least significant bit LSB of the terminal identifier is located at the most significant bit MSB or least significant bit LSB of the first context identifier.
换言之，上述方案也可以被描述为：In other words, the above scheme can also be described as:
所述第一网络设备标识符的一部分中的最低有效位LSB位于所述第二上下文标识符的 最左端比特位或最右端比特位；和/或The least significant bit LSB of a portion of the first network device identifier is located at a leftmost bit or a rightmost bit of the second context identifier; and/or
所述终端标识符的一部分中的最低有效位LSB位于所述第二上下文标识符的最右端比特位或最左端比特位；和/或The least significant bit LSB of a portion of the terminal identifier is located at a rightmost bit or a leftmost bit of the second context identifier; and/or
所述第一网络设备标识符的最低有效位LSB位于所述第一上下文标识符的最左端比特位或最右端比特位；和/或The least significant bit LSB of the first network device identifier is located at a leftmost bit or a rightmost bit of the first context identifier; and/or
所述终端标识符的最低有效位LSB位于所述第一上下文标识符最左端比特位或最右端比特位。The least significant bit LSB of the terminal identifier is located at the leftmost bit or the rightmost bit of the first context identifier.
实施例二可以利用数据本身的特点，简化数据处理过程，以及优化信令开销。该方案中不需要专门通知终端ID的起始位置或者基站ID的终止位置。The second embodiment can utilize the characteristics of the data itself, simplify the data processing process, and optimize the signaling overhead. There is no need to specifically inform the start location of the terminal ID or the termination location of the base station ID in this scheme.
长度指示符Length indicator
实施例三可以使用指示信息来携带所述上下文标识符的长度信息。为了行文方便，本文将上下文标识符中基站ID的长度信息，或终端ID的长度信息，或上下文标识符的长度信息，或终端ID的起始位置，或基站ID的终止位置，统称为上下文标识符的长度信息。通信方可以通过所述长度信息区分出上下文标识符中所需ID的部分，进而完成识别出ID的功能。该实施例可以应用于完整的上下文标识符或者截短的上下文标识符。这里不限定第一还是第二。Embodiment 3 may use indication information to carry length information of the context identifier. For convenience of text, the length information of the base station ID in the context identifier, or the length information of the terminal ID, or the length information of the context identifier, or the starting position of the terminal ID, or the termination position of the base station ID are collectively referred to as a context identifier. The length information of the character. The communication party can distinguish the part of the context identifier in the context identifier by using the length information, thereby completing the function of identifying the ID. This embodiment can be applied to a complete context identifier or a truncated context identifier. The first or second is not limited here.
实施例三类似于实施例一的方法，只是进一步包含了长度信息的使用。该方法还包括：第一网络设备发送配置信息，所述配置信息还包括指示信息，所述指示信息包括所述第一上下文标识符的长度信息。作为可以替换的实施方式，所述第一设备不专门发送配置信息，而将长度信息作为上下文标识符的一部分发送。如图6所示，所述第一上下文标识符或第二上下文标识符分别包括各自的长度信息。这样，接收方只需要从长度信息中获取基站ID或终端ID的位置，即可从中获取对应的ID。Embodiment 3 is similar to the method of Embodiment 1, except that the use of length information is further included. The method further includes: the first network device transmitting configuration information, the configuration information further comprising indication information, the indication information including length information of the first context identifier. As an alternative embodiment, the first device does not specifically send configuration information, but transmits the length information as part of the context identifier. As shown in FIG. 6, the first context identifier or the second context identifier respectively include respective length information. In this way, the receiver only needs to obtain the location of the base station ID or the terminal ID from the length information, and the corresponding ID can be obtained therefrom.
实施例三可以使用截短的ID部分的方案，如终端在收到完整的第一上下文标识符后，根据长度信息，确定基站ID所占的比特位置，截断其中低位的M比特，再截取终端ID低位的N比特，组成M+N比特的上下文标识符。在加上所述长度信息，形成发送给第二网络设备的第二上下文标识符，如图6所示。Embodiment 3 may use a scheme of truncating the ID part. For example, after receiving the complete first context identifier, the terminal determines the bit position occupied by the base station ID according to the length information, cuts off the low M bit, and intercepts the terminal. The N bits of the lower ID form the context identifier of the M+N bits. The length information is added to form a second context identifier that is sent to the second network device, as shown in FIG.
作为一种变形，实施例三可以脱离实施例一的方法，即不依赖于是否截短上下文标识符的方法。终端从第一网络设备获取第一上下文标识符，所述第一上下文标识符包括基站ID以及终端ID，和网络设备标识符的长度；终端向第二网络设备发送请求消息，所述请求消息包括所述第一上下文标识符，上下文标识符中的网络设备标识符的长度是可变的。所谓可变包括根据网络设备的指示，其数值在一个范围内变化。所述第二网络设备根据收到的第一上下文标识符中的网络设备标识符的长度确定基站ID所占的长度，进而确定其中的基站ID。根据基站ID向对应的第一网络设备发送上下文获取请求。As a variant, the third embodiment can be deviated from the method of the first embodiment, that is, the method does not depend on whether or not the context identifier is truncated. The terminal acquires a first context identifier from the first network device, where the first context identifier includes a base station ID and a terminal ID, and a length of the network device identifier; the terminal sends a request message to the second network device, where the request message includes The first context identifier, the length of the network device identifier in the context identifier, is variable. The so-called variable includes the value of the network device varies within a range. The second network device determines the length occupied by the base station ID according to the length of the network device identifier in the received first context identifier, and further determines the base station ID therein. Sending a context acquisition request to the corresponding first network device according to the base station ID.
进一步的，所述网络设备标识符的长度信息放置在所述上下文标识符的最左侧或者最右侧。所述基站ID和终端ID相邻放置在网络设备标识符的右侧或者左侧。Further, the length information of the network device identifier is placed at the leftmost or rightmost side of the context identifier. The base station ID and the terminal ID are placed adjacent to the right or left side of the network device identifier.
通过长度信息的使用，所述上下文标识符所包含的不同ID，特别是长度可以变化的ID可以被识别，因而满足了可变长ID的通信需求。不论所述上下文标识符所携带的ID的长短如何变化，都可以通过长度信息来准确识别出来。By the use of the length information, the different IDs contained in the context identifier, in particular the IDs whose length can be changed, can be identified, thus satisfying the communication requirements of the variable length ID. Regardless of how the length of the ID carried by the context identifier changes, it can be accurately identified by the length information.
非激活态的恢复连接过程Inactive connection recovery process
实施例四将实施例一至三中的一个，应用于恢复连接过程。更具体的，该实施例可以支持非激活状态下的恢复标识符。Embodiment 4 applies one of Embodiments 1 to 3 to the recovery connection process. More specifically, this embodiment can support recovery identifiers in an inactive state.
包括而不限定的，第一上下文标识符或第二上下文标识符可以被称作非激活无线网络临时标识(inactive radio network temporary identifier,I-RNTI)。该标识符可以包括所述非激活态的终端的上下文(context)信息。或者包括所述第一上下文标识符或第二上下文标识符的配置信息是上述I-RNTI。第一上下文标识符或者第二上下文标识符可以是完整的上下文标识符也可以是截短的上下文标识符。Including, without limitation, the first context identifier or the second context identifier may be referred to as an inactive radio network temporary identifier (I-RNTI). The identifier may include context information of the terminal in the inactive state. Or the configuration information including the first context identifier or the second context identifier is the above-mentioned I-RNTI. The first context identifier or the second context identifier may be a complete context identifier or a truncated context identifier.
如图7所示，步骤701与图2的步骤201相同，步骤703与图2的步骤703相同。可选的，步骤702与图2的步骤202相同。As shown in FIG. 7, step 701 is the same as step 201 of FIG. 2, and step 703 is the same as step 703 of FIG. Optionally, step 702 is the same as step 202 of FIG.
第二网络设备收到第二上下文标识符，识别出其指示的基站ID，以及终端ID。具体识别的方式可以参考上文实施例一至实施例三，不再赘述。The second network device receives the second context identifier, identifies the indicated base station ID, and the terminal ID. For the specific identification, refer to the foregoing Embodiment 1 to Embodiment 3, and details are not described herein again.
707，第二网络设备根据第二上下文标识符所指示的上下文信息，确定为该终端恢复连接。例如网络确定当前网络尚有资源为终端服务，则确定为终端获取上下文并恢复连接。其他软硬件条件都可以被用来参考以决定是否可以恢复连接，不一一赘述。707. The second network device determines, according to the context information indicated by the second context identifier, that the terminal resumes the connection. For example, if the network determines that the current network still has resources for the terminal service, it is determined that the terminal acquires the context and resumes the connection. Other hardware and software conditions can be used to refer to determine whether the connection can be restored, not to repeat them.
709，第二网络设备发送恢复连接通知，启动恢复连接流程。具体恢复连接的过程可以参考现有技术的步骤，不再赘述。709. The second network device sends a resume connection notification, and initiates a resume connection process. For the process of restoring the connection, reference may be made to the steps of the prior art, and details are not described herein.
在步骤707中，所述第二网络设备识别第二上下文标识符指示的基站ID以及终端ID后，若该上下文信息存储在第二网络设备，则第二网络设备可以直接获得该上下文信息。若该上下文没有存储在所述第二网络设备，则需要发起上下文取回过程。作为一个例子，所述第二网络设备将第二上下文标识符中的基站ID比特取出，并倒序排列，将倒序后的这些比特与所述第二网络设备所存储的各个基站ID进行比较。这种比较可以是所有比特的比较，也可以是只比较低位的一些比特。当比较结果一致时，识别所述的基站ID(包括补全未比较的高位部分)。所述所存储的各个基站ID可以是与所述第二网络设备相邻的其他网络设备的ID，也可以是第二网络设备基于其他原因而预先保留的ID的列表。In step 707, after the second network device identifies the base station ID indicated by the second context identifier and the terminal ID, if the context information is stored in the second network device, the second network device may directly obtain the context information. If the context is not stored in the second network device, then a context retrieval process needs to be initiated. As an example, the second network device extracts the base station ID bits in the second context identifier and arranges them in reverse order, and compares the reversed bits with the respective base station IDs stored by the second network device. This comparison can be a comparison of all bits, or it can be a bit that compares only the lower bits. When the comparison results are consistent, the base station ID is identified (including complementing the uncompared high-order portion). Each of the stored base station IDs may be an ID of another network device adjacent to the second network device, or may be a list of IDs reserved by the second network device for other reasons.
可选的，图7的方法还包括如下步骤(图中，虚线表示该步骤不是必须的)：Optionally, the method of FIG. 7 further includes the following steps (in the figure, a dotted line indicates that the step is not necessary):
705，第二网络设备向第一网络设备发送上下文取回请求，所述上下文取回请求包括终端ID或者终端ID的一部分。可以理解的，参照实施例二中描述的截短的方案，截短的终端ID也可以实现识别目标终端的目的。所述第二网络设备可以根据识别出来的基站ID来找到第一网络设备，进而向其发起所述上下文取回请求。705. The second network device sends a context retrieval request to the first network device, where the context retrieval request includes a terminal ID or a part of the terminal ID. It can be understood that with reference to the truncated scheme described in Embodiment 2, the truncated terminal ID can also achieve the purpose of identifying the target terminal. The second network device may find the first network device according to the identified base station ID, and then initiate the context retrieval request to the second network device.
706，第一网络设备响应于所述上下文取回请求，将所述终端ID或者终端ID的一部分所指示的终端的上下文信息通过上下文取回请求响应发给所述第二网络设备。706. The first network device sends, according to the context retrieval request, context information of the terminal indicated by the terminal ID or a part of the terminal ID to the second network device by using a context retrieval request response.
本实施例中，所述第一、第二网络设备以及终端，因为采用了实施例一至三的技术方案，因而继承了相应的优点，并可以满足非激活态下恢复连接的需求。In this embodiment, the first and second network devices and the terminal adopt the technical solutions of Embodiments 1 to 3, thereby inheriting corresponding advantages and satisfying the requirement of restoring the connection in an inactive state.
上述实施例一至四中，所涉及的所述第一、第二网络设备以及终端构成了一个通信***。下面继续分别从第一网络设备、第二网络设备、终端的角度分别描述各实体所使用的 方法以及装置。可以理解这些设备都是源自实施例一至四中的步骤，只是描述的角度不同，因而具备相似的优点。本领域技术人员可以根据实施例一至四的步骤准确了解以下文字所代表的含义。In the above embodiments 1 to 4, the first and second network devices and terminals involved constitute a communication system. The following continues to describe the methods and devices used by the entities from the perspectives of the first network device, the second network device, and the terminal, respectively.
