Description
本申请涉及通信技术领域,尤其涉及一种获取寻呼参数的方法及装置。The present application relates to the field of communications technologies, and in particular, to a method and an apparatus for obtaining paging parameters.
在长期演进(Long Term Evolution,LTE)系统中,终端设备(简称终端)存在两种无线资源控制(Radio Resource Control,RRC)状态—RRC_CONNECTED状态和RRC_IDLE状态。如图1所示,在RRC_CONNECTED状态下,终端的RRC连接(终端与基站之间的连接)和S1连接(基站与核心网之间的连接)都是存在的。这样核心网设备就可以通过这两个连接,向终端发送数据。在RRC_IDLE状态下,终端的RRC连接和S1连接都是中断的,核心网无法发送数据给该终端。这种情况下,如果核心网有数据要发送给该终端,其需要通过触发寻呼过程来寻找该终端。具体做法如图3右图所示,核心网发送一个寻呼请求消息给该终端的寻呼通知区域内的所有基站,让这些基站发送寻呼消息寻找该终端。如果该终端从某个基站收到寻呼消息,会发起随机接入过程,建立RRC连接和S1连接,即从RRC_IDLE状态转移到RRC_CONNECTED状态,这样终端就可以从核心网接收数据了。In a Long Term Evolution (LTE) system, a terminal device (referred to as a terminal) has two Radio Resource Control (RRC) states—an RRC_CONNECTED state and an RRC_IDLE state. As shown in FIG. 1, in the RRC_CONNECTED state, the RRC connection (connection between the terminal and the base station) and the S1 connection (the connection between the base station and the core network) of the terminal are both present. In this way, the core network device can send data to the terminal through the two connections. In the RRC_IDLE state, the RRC connection and the S1 connection of the terminal are both interrupted, and the core network cannot send data to the terminal. In this case, if the core network has data to send to the terminal, it needs to find the terminal by triggering the paging process. As shown in the right figure of FIG. 3, the core network sends a paging request message to all base stations in the paging notification area of the terminal, and these base stations send paging messages to find the terminal. If the terminal receives the paging message from a certain base station, it initiates a random access procedure, establishes an RRC connection and an S1 connection, that is, transitions from the RRC_IDLE state to the RRC_CONNECTED state, so that the terminal can receive data from the core network.
5G(5th generation mobile system)通信系统中引入了一个新的状态,不同于RRC_CONNECTED状态和RRC_IDLE状态,本申请暂时称为第三状态,如图1所示,该状态下的终端的RRC连接是中断的,即终端与基站之间的连接是中断的;而基站与核心网之间的连接是存在的。在该状态下,终端也无法从核心网设备接收数据,但是,由于基站与核心网之间的连接是存在的,终端只需要建立RRC连接,就可以转移到RRC_CONNECTED状态。The 5G (5th generation mobile system) communication system introduces a new state, which is different from the RRC_CONNECTED state and the RRC_IDLE state. This application is temporarily referred to as the third state. As shown in FIG. 1, the RRC connection of the terminal in this state is interrupted. That is, the connection between the terminal and the base station is interrupted; and the connection between the base station and the core network exists. In this state, the terminal cannot receive data from the core network device. However, since the connection between the base station and the core network exists, the terminal only needs to establish an RRC connection, and can transit to the RRC_CONNECTED state.
当终端处于第三状态时,触发寻呼的并非是核心网设备,而是基站,但目前基站没有与寻呼相关的参数,因此无法完成寻呼。When the terminal is in the third state, the paging is not the core network device, but the base station, but currently the base station has no paging-related parameters, so the paging cannot be completed.

Or a small station, a micro station, a transmission reception point (TRP), or a relay station, an access point, an in-vehicle device, a wearable device, or the like.
以下实施例以基站与终端为例进行说明。如图2所示,本发明实施例寻呼参数的方法涉及的网络系统架构包含终端,基站和核心网。The following embodiments are described by taking a base station and a terminal as an example. As shown in FIG. 2, the network system architecture involved in the method for paging parameters in the embodiment of the present invention includes a terminal, a base station, and a core network.
5G(5th generation mobile system)通信系统中引入了一个新的状态,不同于RRC_CONNECTED状态和RRC_IDLE状态,本申请暂时称为第三状态,未来5G标准中可能称为RRC_INACTIVE状态。如图1所示,该状态下终端与基站之间的连接(RRC连接)是中断的,而基站与核心网之间的连接是存在的,这个连接在5G中暂时称为NG连接,与LTE中的S1连接类似。在该状态下,终端也无法从核心网接收数据,但是,由于NG连接是存在的,终端只需要建立与基站之间的RRC连接,就可以转移到RRC_CONNECTED状态。A new state is introduced in the 5G (5th generation mobile system) communication system, which is different from the RRC_CONNECTED state and the RRC_IDLE state. This application is temporarily referred to as the third state, and may be referred to as the RRC_INACTIVE state in the future 5G standard. As shown in FIG. 1, the connection between the terminal and the base station (RRC connection) is interrupted in this state, and the connection between the base station and the core network exists. This connection is temporarily called NG connection in 5G, and LTE. The S1 connection is similar. In this state, the terminal cannot receive data from the core network. However, since the NG connection exists, the terminal only needs to establish an RRC connection with the base station, and can transit to the RRC_CONNECTED state.
LTE中,当核心网有数据要发送该终端时,由核心网发送寻呼请求消息给该终端寻呼通知区域内的所有基站,让这些基站发送寻呼消息寻找该终端,如图3右图所示。In LTE, when the core network has data to send the terminal, the core network sends a paging request message to all the base stations in the paging notification area of the terminal, and these base stations send paging messages to find the terminal, as shown in the right diagram of FIG. Shown.
当终端处于第三状态时,由于NG连接是存在的,因此核心网无法确定该终端是处于RRC_CONNECTED状态还是第三状态,因为核心网并不知道RRC连接的情况,因此核心网会统一当成RRC_CONNECTED状态。当核心网有数据要发送给该终端时,其会将数据发送给基站,而不会触发寻呼过程。基站收到数据后,发现终端处于第三状态,无法将数据发送给该终端,会触发寻呼过程。具体做法如图3左图所示,触发寻呼的基站,也就是终端进入第三状态之前最后连接(RRC连接)的那个基站,称为锚点基站,该锚点基站还保留在终端的上下文信息,锚点基站会发送寻呼请求消息给该终端的寻呼通知区域内的所有基站,让这些基站发送寻呼消息寻找该终端。也就是说,在第三状态下,寻呼过程可以由锚点基站来触发,这与上文提到的由核心网触发的寻呼过程是两种独立的寻呼机制。When the terminal is in the third state, because the NG connection exists, the core network cannot determine whether the terminal is in the RRC_CONNECTED state or the third state. Because the core network does not know the RRC connection, the core network is unified as the RRC_CONNECTED state. . When the core network has data to send to the terminal, it will send the data to the base station without triggering the paging process. After receiving the data, the base station finds that the terminal is in the third state and cannot send data to the terminal, which triggers the paging process. As shown in the left figure of FIG. 3, the base station that triggers paging, that is, the base station that is connected last (RRC connection) before the terminal enters the third state, is called an anchor base station, and the anchor base station also remains in the context of the terminal. Information, the anchor base station sends a paging request message to all base stations in the paging notification area of the terminal, and causes the base stations to send a paging message to find the terminal. That is to say, in the third state, the paging process can be triggered by the anchor base station, which is two independent paging mechanisms with the paging process triggered by the core network mentioned above.
为了便于区分,本文中我们称前一种寻呼机制为“核心网触发式寻呼机制”,后一种为“基站触发式寻呼机制”。In order to facilitate the distinction, in this paper, we refer to the former paging mechanism as "core network triggered paging mechanism" and the latter as "base station triggered paging mechanism".
不论基站触发式寻呼机制还是核心网触发式寻呼机制,寻呼通知区域内的基站要执行寻呼操作,都需要一些与寻呼相关的参数。例如,终端的国际移动用户识别码(International Mobile Subscriber Identification Number,IMSI)、终端特定的非连续接收(Discontinuous Reception,DRX)周期、终端设备的标识、终端设备的寻呼通知区域范围等。在核心网触发式寻呼机制中,这些参数是核心网通过寻呼请求消息发送给寻呼通知区内的基站的。在基站触发式寻呼机制中,由于寻呼是锚点基站触发的,这些参数需要由锚点基站通过寻呼请求消息发送给寻呼通知区域内的基站。因为LTE中没有基站触发式寻呼机制,根据当前LTE协议,基站是不会管理终端的这些寻呼参数的。因此,基于LTE的寻呼机制,是无法支持基站触发式寻呼机制的。因此,需要设计一种方法来解决锚点基站缺失寻呼参数的问题。Regardless of the base station triggered paging mechanism or the core network triggered paging mechanism, the base station in the paging notification area needs to perform some paging related parameters to perform paging operations. For example, an International Mobile Subscriber Identification Number (IMSI) of the terminal, a terminal-specific discontinuous reception (DRX) period, an identifier of the terminal device, a paging notification area range of the terminal device, and the like. In the core network triggered paging mechanism, these parameters are sent by the core network to the base station in the paging notification area through a paging request message. In the base station triggered paging mechanism, since the paging is triggered by the anchor base station, these parameters need to be sent by the anchor base station to the base station in the paging notification area through the paging request message. Because there is no base station triggered paging mechanism in LTE, according to the current LTE protocol, the base station does not manage these paging parameters of the terminal. Therefore, the LTE-based paging mechanism cannot support the base station triggered paging mechanism. Therefore, there is a need to devise a method to solve the problem of missing paging parameters at the anchor base station.
核心网包括两种设备:一是用户面核心网设备,例如:LTE中的服务网关(Serving GateWay,S-GW);二是控制面核心网设备,例如:LTE中的移动性管理实体(Mobility Management Entity,MME)。5G网络中用户面核心网设备称为用户面实体(User Plane Function,UPF),控制面核心网设备称为接入和移动性管理实体(Access and Mobility Management Function,AMF)。The core network includes two types of devices: one is a user plane core network device, for example, a Serving GateWay (S-GW) in LTE; the other is a control plane core network device, for example, a mobility management entity in LTE (Mobility) Management Entity, MME). The user plane core network device in the 5G network is called User Plane Function (UPF), and the control plane core network device is called Access and Mobility Management Function (AMF).
一个实施例中,用户面核心网设备,如UPF,有数据要发送给第三状态的终端时,将数据发送给该终端的锚点基站。锚点基站收到数据后知道无法直接发送数据给该终端,决定触发寻呼过程。触发寻呼之前,其先发送寻呼参数请求消息给控制面核心网设备,如AMF,控制面核心网设备收到该请求消息后,将终端的寻呼参数发送给锚点基站。锚点基站收到这些参数后就可以触发针对该终端的寻呼了。In one embodiment, the user plane core network device, such as the UPF, sends data to the anchor base station of the terminal when there is data to be sent to the terminal in the third state. After receiving the data, the anchor base station knows that it cannot directly send data to the terminal, and decides to trigger the paging process. Before the paging is triggered, the paging parameter request message is sent to the control plane core network device, such as the AMF. After receiving the request message, the control plane core network device sends the paging parameter of the terminal to the anchor base station. After receiving these parameters, the anchor base station can trigger a page for the terminal.
参考图4,该获取寻呼参数的方法包括:Referring to FIG. 4, the method for obtaining paging parameters includes:

After receiving the request message, the core network device sends a response message to send the user context of the terminal to the base station. The above procedure has been defined in the LTE, but the terminal context does not include the paging parameter of the terminal. In this embodiment, the paging parameter of the terminal is also included in the context of the user sent by the core network device to the terminal.
又一实施例中,终端向基站发送NAS服务请求,基站该NAS服务请求转发给核心网设备,核心网设备收到后,将该终端的寻呼参数发送给基站;该方法可以应用到上述终端初始接入基站的场景,也可以用于其它场景,例如终端的切换场景,位置更新场景等。In another embodiment, the terminal sends a NAS service request to the base station, and the NAS service request is forwarded to the core network device, and after receiving the core network device, the paging parameter of the terminal is sent to the base station; the method may be applied to the terminal.
