Description

用于寻呼的方法和装置 技术领域
本申请涉及通信领域，并且更具体地，涉及一种用于寻呼的方法和装置。
背景技术
随着通信技术的发展，越来越多的终端设备支持同时插入多张用户身份识别模块(subscriber identity module，SIM)卡。不同的SIM卡可以驻留在不同制式的不同小区或相同小区，也可以驻留在相同制式的不同小区或同一小区，并分别进行网络注册，多张SIM卡完成注册之后，SIM卡各自注册的网络将为SIM卡分配终端设备标识(user equipment identify，UE ID)，根据各SIM卡分别对应的寻呼配置参数和各SIM卡分别对应的UE ID确定各SIM卡的寻呼时机(paging occasion，PO)。
对于多SIM卡的终端设备，有可能多张SIM卡分别对应的PO全部或者部分重叠，该多张SIM卡分别对应的寻呼会受到影响，无法及时响应寻呼。

作为示例而非限定，在本申请实施例中，可穿戴设备也可以称为穿戴式智能设备，是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称，如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上，或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备，更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能，例如：智能手表或智能眼镜等，以及只专注于某一类应用功能，和其它设备如智能手机配合使用，如各类进行体征监测的智能手环、智能首饰等。
此外，在本申请实施例中，终端设备还可以是IoT系统中的终端设备，IoT是未来信息技术发展的重要组成部分，其主要技术特点是将物品通过通信技术与网络连接，从而实现人机互连，物物互连的智能化网络。在本申请实施例中，IOT技术可以通过例如窄带(narrow band，NB)技术，做到海量连接，深度覆盖，终端省电。
此外，在本申请实施例中，终端设备还可以包括智能打印机、火车探测器、加油站等传感器，主要功能包括收集数据(部分终端设备)、接收网络设备的控制信息与下行数据，并发送电磁波，向网络设备传输上行数据。
本申请实施例中的接入网设备可以是用于与终端设备通信的任意一种具有无线收发功能的通信设备。该设备包括但不限于：演进型节点B(evolved Node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(Node B，NB)、基站控制器(base station controller，BSC)、基站收发台(base transceiver station，BTS)、家庭基站(home evolved NodeB，HeNB，或home Node B，HNB)、基带单元(baseBand unit，BBU)，无线保真(wireless fidelity，WIFI)系统中的接入点(access point，AP)、无线中继节点、无线回传节点、传输点(transmission point，TP)或者发送接收点(transmission and reception point，TRP)等，还可以为5G，如，NR，系统中的gNB，或，传输点(TRP或TP)，或，接入回传一体化(integrated access and backhaul，IAB)，5G系统中的基站的一个或一组(包括多个天线面板)天线面板，或者，还可以为构成gNB或传输点的网络节点， 如基带单元(BBU)，或，分布式单元(distributed unit，DU)等。
在一些部署中，本申请实施例中的接入网设备可以是指集中单元(central unit，CU)或者分布式单元(distributed unit，DU)或者，接入网设备包括CU和DU。gNB还可以包括有源天线单元(active antenna unit，AAU)。CU实现gNB的部分功能，DU实现gNB的部分功能。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)，分组数据汇聚层协议(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(media access control，MAC)层和物理(physical，PHY)层的功能。AAU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，因而，在这种架构下，高层信令，如RRC层信令，也可以认为是由DU发送的，或者，由DU+AAU发送的。可以理解的是，网络设备可以为包括CU节点、DU节点、AAU节点中一项或多项的设备。此外，可以将CU划分为接入网(radio access network，RAN)中的网络设备，也可以将CU划分为核心网(core network，CN)中的网络设备，本申请对此不做限定。
进一步地，CU还可以划分为控制面的中央单元(CU-CP)和用户面的中央单元(CU-UP)。其中，CU-CP和CU-UP也可以部署在不同的物理设备上，CU-CP负责控制面功能，主要包含RRC层和PDCP-C层。PDCP-C层主要负责控制面数据的加解密，完整性保护，数据传输等。CU-UP负责用户面功能，主要包含SDAP层和PDCP-U层。其中SDAP层主要负责将核心网的数据进行处理并将流(flow)映射到承载。PDCP-U层主要负责数据面的加解密，完整性保护，头压缩，序列号维护，数据传输等至少一种功能。具体地，CU-CP和CU-UP通过通信接口(例如，E1接口)连接。CU-CP代表接入网设备通过通信接口(例如，Ng接口)和核心网设备连接，通过通信接口(例如，F1-C(控制面)接口)和DU连接。CU-UP通过通信接口(例如，F1-U(用户面)接口)和DU连接。
还有一种可能的实现，PDCP-C层也包含在CU-UP中。
可以理解的是，以上关于CU和DU，以及CU-CP和CU-UP的协议层划分仅为示例，也可能有其他的划分方式，本申请实施例对此不做限定。
本申请实施例所提及的接入网设备可以为包括CU、或DU、或包括CU和DU的设备、或者控制面CU节点(CU-CP节点)和用户面CU节点(CU-UP节点)以及DU节点的设备。
接入网设备和终端设备可以部署在陆地上，包括室内或室外、手持或车载；也可以部署在水面上；还可以部署在空中的飞机、气球和卫星上。本申请实施例中对无线接入网设备和终端设备的应用场景不做限定。
在本申请实施例中，终端设备或网络设备包括硬件层、运行在硬件层之上的操作系统层，以及运行在操作系统层上的应用层。该硬件层包括中央处理器(central processing unit，CPU)、内存管理单元(memory management unit，MMU)和内存(也称为主存)等硬件。该操作系统可以是任意一种或多种通过进程(process)实现业务处理的计算机操作系统，例如，Linux操作系统、Unix操作系统、Android操作系统、iOS操作系统或windows操作系统等。该应用层包含浏览器、通讯录、文字处理软件、即时通信软件等应用。并且， 本申请实施例并未对本申请实施例提供的方法的执行主体的具体结构特别限定，只要能够通过运行记录有本申请实施例的提供的方法的代码的程序，以根据本申请实施例提供的方法进行通信即可，例如，本申请实施例提供的方法的执行主体可以是终端设备或网络设备，或者，是终端设备或网络设备中能够调用程序并执行程序的功能模块。
另外，本申请的各个方面或特征可以实现成方法、装置或使用标准编程和/或工程技术的制品。本申请中使用的术语“制品”涵盖可从任何计算机可读器件、载体或介质访问的计算机程序。例如，计算机可读介质可以包括，但不限于：磁存储器件(例如，硬盘、软盘或磁带等)，光盘(例如，压缩盘(compact disc，CD)、数字通用盘(digital versatile disc，DVD)等)，智能卡和闪存器件(例如，可擦写可编程只读存储器(erasable programmable read-only memory，EPROM)、卡、棒或钥匙驱动器等)。另外，本文描述的各种存储介质可代表用于存储信息的一个或多个设备和/或其它机器可读介质。术语“机器可读存储介质”可包括但不限于，无线信道和能够存储、包含和/或承载指令和/或数据的各种其它介质。
为便于理解本申请实施例，首先以图1中示出的通信系统为例详细说明适用于本申请实施例的通信系统。图1是适用于本申请实施例的用于寻呼的方法的通信系统100的示意图。如图1所示，该通信系统100可以包括至少一个网络设备，例如图1所示的网络设备110；该通信系统100还可以包括至少一个终端设备，例如图1所示的终端设备120。网络设备110与终端设备120可通过无线链路通信。各通信设备，如网络设备110或终端设备120，均可以配置多个天线。对于该通信系统100中的每一个通信设备而言，所配置的多个天线可以包括至少一个用于发送信号的发射天线和至少一个用于接收信号的接收天线。因此，该通信系统100中的各通信设备之间，如网络设备110与终端设备120之间，可通过多天线技术通信。
应理解，图1仅为便于理解而示例的简化示意图，该通信系统100中还可以包括其他网络设备或者还可以包括其他终端设备，图1中未予以画出。
具体地，本申请实施例中涉及的终端设备支持同时插入多张SIM卡。以支持两张SIM卡为例，其中，一张SIM用于私人业务，另一张SIM用于工作用；或者一张SIM用于数据业务，另一张SIM卡用于语音业务。双卡可以属于同一移动运营商也可以属于不同移动运营商，可以属于同一制式(例如，NR、LTE、WCDMA、TDMA2000、或GSM)也可以属于不同的制式。根据终端设备的收发能力不同，可以将双SIM的终端设备分为以下三种：
1、被动(passive)模式的终端设备：终端设备尽管能插入两张SIM卡，但是同一个时间只有一张SIM能使用；
2、双卡双待(dual SIM dual standby，DSDS)模式的终端设备：终端设备中的两张SIM卡共享一套接收机，对于处于空闲(idle)态的终端设备监听两个SIM卡分别对应的寻呼消息，例如idle态或去活动(inactive)态的终端设备可以采用时分复用(time division multiple，TDM)的方式来进行监听两个SIM卡分别对应的寻呼消息。
3、双卡双激活(dual SIM dual active，DSDA)模式的终端设备：终端设备中的两张SIM卡有各自的收发机。两张SIM卡可以同时处于连接态，即终端设备可以同时接收和发送两张SIM卡的数据。
为便于理解本申请实施例，对本申请实施例中涉及的几个基本概念做简单说明。应理 解，下文中所介绍的基本概念是以NR协议中规定的基本概念为例进行简单说明，但并不限定本申请实施例只能够应用于NR系统。因此，以NR系统为例描述时出现的标准名称，都是功能性描述，具体名称并不限定，仅表示设备的功能，可以对应的扩展到其它系统，比如2G、3G、4G或未来通信系统中。
1、寻呼机制。
当某个终端设备没有数据传输时，为了省电，该终端设备进入无线资源控制空闲(radio resource control IDLE，RRC_IDLE)态或无线资源控制去活动(radio resource control INACTIVE，RRC_INACTIVE)态(也可以简称为INACTIVE态)。处于RRC_IDLE或RRC_INACTIVE态下的终端设备以一定的周期(即该终端设备的寻呼周期)在一定的位置醒过来，监听网络是否有寻呼自己，该位置称为该终端设备的PO，在其他位置，该终端设备进行睡眠以省电。当有下行数据到达(即网络要发送数据给终端设备)时：
1)对于RRC_IDLE态下的终端设备，核心网设备发送核心网寻呼(CN paging)消息给接入网设备。该CN paging消息中包括UE ID，本申请实施例中UE ID可以称为终端设备的标识、用户标识、或终端设备标识等。可选地，该UE ID可以是核心网设备分配给该终端设备的S临时移动用户标识(S-temporary mobile subscriber identity，S-TMSI)、国际移动用户识别码(international mobile subscriber identity，IMSI)、基于S-TMSI确定的标识、基于IMSI确定的标识或者其它可以识别终端设备的标识。UE ID可以用于计算该终端设备的PO在寻呼帧(paging frame，PF)中的位置。进一步地，接入网设备向终端设备发送寻呼(paging)消息，该paging消息中包括上述的UE ID，用于指示寻呼的终端设备。
可选地，CN paging消息中还可以包括核心网设备分配给该终端设备的寻呼不连续接收(discontinuous reception，DRX)周期，为了描述方便，本申请中称之为T1。应理解，小区的系统信息中会包括一个小区级的寻呼DRX周期，为了描述方便，本申请中称之为T2。对于处于idle态的终端设备，用于计算PO的寻呼DRX周期是T1和T2的最小值，该最小值记为T。
2)对于RRC_INACTIVE状态下的终端设备，接入网设备发送无线接入网(radio access network，RAN)paging消息给RNA内的其他接入网设备，RAN paging消息中包括RAN UE ID。可选地，该RAN UE ID可以是非激活态无线网络临时标识(inactive radio network temporary identity，I-RNTI)，该I-RNTI可以在RNA内唯一识别终端设备。其他接入网设备发给终端设备的空口paging消息中包括该I-RNTI，用于指示寻呼的终端设备。可选地，RAN paging消息中还可以包括UE ID索引(index)，UE ID index一般为根据UE ID确定的，比如为S-TMSI mod 1024或者IMSI mod 1024，该UE ID index可以用于计算该终端设备的PO在PF中的位置。
可选的，RAN paging也可以包括接入网设备给终端设备分配的寻呼DRX周期T3。对于处于inactive态的终端设备，用于计算寻呼时机的寻呼DRX周期是T1、T2和T3的最小值，该最小值记为T。
在得到上述的T之后，接入网设备能够基于UE ID、T以及小区的寻呼配置参数计算出终端设备的PO。其中，小区的寻呼配置参数可以在小区的系统信息中获得。可选地，小区系统信息中的小区寻呼配置参数包括：defaultPagingCycle、nAndPagingFrameOffset和Ns。该defaultPagingCycle即上述的T2，该nAndPagingFrameOffset可以得出寻呼帧偏 置(PF_offset)以及一个寻呼周期内PF的个数N，该Ns指示一个寻呼帧里的PO个数。
计算出终端设备的PO后，接入网设备在该终端设备的PO内，在空口发送paging消息，该paging消息中包括终端设备的寻呼标识。可以理解的，RRC_INACTIVE态的终端设备可以接收RAN paging，此时paging消息中的终端设备的寻呼标识可以为I-RNTI；RRC_INACTIV态的终端设备也可以接收CN paging，比如接入网设备或核心网设备释放该终端设备的上下文信息以及该终端设备在接入网设备和核心网设备间的连接。从网络设备的角度，该终端设备为RRC_IDLE态，因此网络设备发送CN paging，此时paging消息中的终端设备的寻呼标识可以为S-TMSI、IMSI、基于S-TMSI确定的标识、基于IMSI确定的标识或者其它可以识别终端设备的标识。终端设备在PO内监听物理信道接收paging消息，若收到paging消息且根据paging消息中的终端设备的寻呼标识确定自己被寻呼后，会在当前驻留的小区上发起新的RRC连接建立过程(比如收到CN paging)或RRC连接恢复过程(比如收到RAN paging)以进入无线资源控制连接(radio resource control CONNECTED，RRC_CONNECTED)态。
为了更形象地理解上述的寻呼过程，以RRC_IDLE态下的终端设备被核心网设备寻呼为例结合图2说明上述的寻呼过程。图2是本申请实施例提供的一种寻呼流程示意图。该寻呼流程包括：
S210，核心网设备确定有下行数据发送给终端设备。
S220，核心网设备向接入网设备发送核心网寻呼消息。
该核心网寻呼消息中包括核心网设备分配给该终端设备的S-TMSI或IMSI以及寻呼DRX周期。
S230，接入网设备确定终端设备的PO。
S240，接入网设备向终端设备发送寻呼消息。
具体地，接入网设备在终端设备的PO内发送该寻呼消息。对应地，终端设备在自己的PO内去接收该寻呼消息。
2、PO计算。
在NR中，UE的PO所在的PF通过(SFN+PF_offset)mod T＝(T div N)*(UE_ID mod N)确定，其中，系统帧号(system frame number，SFN)标识PF的帧号，PF_offset为PF的偏移量，T为UE的寻呼周期，单位为帧，N标识一个寻呼周期内PF的个数(T div N就是每几个连续帧有一个PF)，UE ID为S-TMSI mode 1024或IMSI mode 1024，其中PF_offset、T和N的值均来自当前小区的系统信息，或与当前小区的寻呼配置参数有关，其中，PF_offset可以为0。
在确定PF之后，确定UE的PO在PF里的位置，例如可以分为两步：
第一步：通过i_s＝floor(UE_ID/N)mod Ns获得PO的编号，其中，i_s为PO的编号，Ns为一个PF中PO的个数，Ns的值来自当前小区的信息；
第二步：根据PO的编号找到PO的位置，在获取PO的编号后，根据当前小区的寻呼的搜索空间的配置，即可以找到终端设备的PO的配置。
由上述计算PO的流程可知，决定终端设备的PO位置的参数包括UE ID，以及适用于当前小区下所有终端设备的小区寻呼配置参数。当一个终端设备中插入两张SIM卡时，这两张SIM卡会分别进行网络注册，完成注册后，网络将会各自分配(不同或相同)UE ID 给对应的SIM卡。根据各SIM卡所驻留小区的小区寻呼配置参数和各自的UE ID分别计算得出与各个SIM卡对应的PO位置。
对于双SIM卡的UE，有可能计算出两张SIM卡对应的PO位置相同或(部分)重叠(即发生paging冲突问题)。比如上述的DSDS模式的终端设备，由于在某个PO位置终端设备只能监听与一张SIM卡对应的寻呼，如果另一张SIM卡在该PO位置有该终端设备的寻呼，导致另一个SIM卡对应的寻呼终端设备没有接收到，出现漏话等问题。
3、RRC状态。
本申请中涉及的终端设备的RRC状态包括RRC连接态RRC_CONNECTED state、RRC去活动态RRC_INACTIVE state和RRC空闲态RRC_IDLE state，三种状态的转换如图3所示。图3是本申请实施例提供的终端设备的3种RRC状态转换示意图。可以理解的是，终端设备的RRC状态也可以包括RRC_CONNECTED state、RRC_IDLE state。本申请实施例对于终端设备所能对应的RRC状态不做限定。终端设备处于RRC_CONNECTED状态时，终端设备与接入网设备以及核心网设备都已建立链路，当有数据到达网络时可以直接传送到终端设备。
当终端设备处于RRC_INACTIVE状态时，表示终端设备之前和接入网设备以及核心网设备建立了链路，但是终端设备到接入网设备的链路被释放了。虽然链路被释放了，但是终端设备和接入网设备保存终端设备的上下文，当有数据传输时，接入网设备可以快速恢复这段链路。
本申请中称配置终端设备进入RRC_INACTIVE态以及存储终端设备上下文的接入网设备为源接入网设备，或锚点(anchor)接入网设备，或第二接入网设备。即源接入网设备可以理解为存储有终端设备的上下文的接入网设备，和/或，源接入网设备还可以理解为生成用于终端设备进入RRC_INACTIVE状态的配置的接入网设备(例如，anchor接入网设备确定不向目标接入网设备提供终端设备的上下文的场景下，虽然从终端设备角度来看，配置终端设备进入RRC_INACTIVE的消息是目标接入网设备发送的，但是在接入网设备角度来看，是源接入网设备生成的上述消息，并发送给目标接入网设备，目标接入网设备转发给终端设备的)。随着终端设备移动，anchor接入网设备可能发生变化，会有新的anchor接入网设备出现。对于处于RRC_INACTIVE态的终端设备，由于终端设备和接入网设备存储了该终端设备的上下文，因此该终端设备发起RRC恢复请求(RRC resume request)后，若当前服务接入网设备获取到了终端设备上下文，则接入网设备发送给终端设备的响应消息可以进行加密和完整性保护，例如，接入网设备向终端设备发送进行加密和完整性保护的RRC恢复(RRC resume)消息或RRC释放(RRC release)。当下行数据到达时，若网络侧认为终端设备处于非RRC_IDLE态(例如，AMF认为终端设备处于RRC_CONNECTED态或RRC_INACTIVE态、anchor接入网设备认为终端设备处于RRC_INACTIVE态)，核心网设备直接把数据发给anchor接入网设备，anchor接入网设备向无线接入网通知区(RAN notification area，RNA)的其他接入网设备发起RAN paging；若由于各种异常原因，网络侧认为终端设备处于RRC_IDLE态，此时发出CN paging。当终端设备处于RRC_IDLE态时，终端设备与接入网设备和核心网设备之间都没有链路，当有数据传输时，建立终端设备到接入网设备及核心网设备的链路。
此外，为了便于理解本申请实施例，做出以下几点说明。
第一，在本申请中，“用于指示”可以包括用于直接指示和用于间接指示。当描述某一指示信息用于指示A时，可以包括该指示信息直接指示A或间接指示A，而并不代表该指示信息中一定包括有A。
将指示信息所指示的信息称为待指示信息，则具体实现过程中，对待指示信息进行指示的方式有很多种。例如但不限于，可以直接指示待指示信息，如待指示信息本身或者该待指示信息的索引等。也可以通过指示其他信息来间接指示待指示信息，其中该其他信息与待指示信息之间存在关联关系。还可以仅仅指示待指示信息的一部分，而待指示信息的其他部分则是已知的或者提前约定的。例如，还可以借助预先约定(例如协议规定)的各个信息的排列顺序来实现对特定信息的指示，从而在一定程度上降低指示开销。同时，还可以识别各个信息的通用部分并统一指示，以降低单独指示同样的信息而带来的指示开销。
第二，在本申请中第一、第二以及各种数字编号(例如，“#1”、“#2”)仅为描述方便进行的区分，并不用来限制本申请实施例的范围。例如，区分不同的寻呼时机、区分不同的接入网设备等。
第三，在本申请中，“预设的”可包括由网络设备信令指示，或者预先定义，例如，协议定义。其中，“预先定义”可以通过在设备(例如，包括终端设备和网络设备)中预先保存相应的代码、表格或其他可用于指示相关信息的方式来实现，本申请对于其具体的实现方式不做限定。
第四，本申请实施例中涉及的“保存”，可以是指的保存在一个或者多个存储器中。所述一个或者多个存储器，可以是单独的设置，也可以是集成在编码器或者译码器，处理器、或通信装置中。所述一个或者多个存储器，也可以是一部分单独设置，一部分集成在译码器、处理器、或通信装置中。存储器的类型可以是任意形式的存储介质，本申请并不对此限定。
第五，本申请实施例中涉及的“协议”可以是指通信领域的标准协议，例如可以包括LTE协议、NR协议以及应用于未来的通信系统中的相关协议，本申请对此不做限定。
上文结合图1简单介绍了本申请实施例提供的用于寻呼的方法能够应用的场景，以及介绍了本申请实施例中可能涉及到的基本概念，下面将结合附图详细说明本申请实施例提供的用于信道测量的方法。
应理解，本申请实施例提供的方法可以应用于通过多天线技术通信的系统，例如，图1中所示的通信系统100。该通信系统可以包括至少一个网络设备和至少一个终端设备。网络设备和终端设备之间可通过多天线技术通信。
还应理解，下文示出的实施例并未对本申请实施例提供的方法的执行主体的具体结构特别限定，只要能够通过运行记录有本申请实施例的提供的方法的代码的程序，以根据本申请实施例提供的方法进行通信即可，例如，本申请实施例提供的方法的执行主体可以是终端设备或网络设备，或者，是终端设备或网络设备中能够调用程序并执行程序的功能模块。
以下，不失一般性，以网络设备与终端设备之间的交互为例详细说明本申请实施例提供的用于信道测量的方法。
图4是本申请实施例提供的一种用于寻呼的方法示意性流程图。该流程图中执行主体 包括第二接入网设备、第一接入网设备、终端设备和核心网设备。
具体地，图4所示的终端设备支持多个用户身份。为了便于描述以下实施例中以终端设备支持两个用户身份为例进行说明，例如终端设备支持第一用户身份和第二用户身份。应理解本申请对于终端设备具体支持几个用户身份并不限制，可以是支持两个以上的用户身份。由上述可知当终端设备支持第一用户身份和第二用户身份的情况下，可以根据各个用户身份所驻留小区的小区寻呼配置参数和各自的UE ID分别计算得出与各个用户身份的寻呼时机位置。例如，根据第一用户身份所驻留小区的小区寻呼配置参数和第一用户身份的UE ID计算出的寻呼时机为第一寻呼时机，根据第二用户身份所驻留小区的小区寻呼配置参数和第二用户身份的UE ID计算出的寻呼时机为第二寻呼时机。
本申请实施例中所涉及的用户身份可以称为用户身份识别模块(subscriber identity module，SIM)卡，应理解，用户身份称为SIM卡对本申请的保护范围不构成任何限定，可以称为其他的名称，例如，还可以称为全球用户识别模块(universal subscriber identity module，USIM)卡。
另外，本申请所涉及的寻呼时机可以简称为PO，不同寻呼时机的冲突可以称为PO collision，应理解本申请所涉及的寻呼时机称为PO只是一种举例，可以称为其他的名称，为了便于描述下文中将寻呼时机称为PO。
图4中的第二接入网设备为更新PO之前存储有终端设备上下文的接入网设备，第一接入网设备为终端设备以上述的第一用户身份所在的第一小区对应的接入网设备，该第一小区也可以理解为服务小区或当前小区或目标小区等。
该用于寻呼的方法包括以下部分或全部步骤。
S410，终端设备确定发生PO冲突。
可选的，本申请实施例中终端设备确定发生PO冲突的时刻，可以是终端设备获知上述的计算第一PO所需的参数以及计算第二PO所需的参数之后，或者，可以是终端设备接收到寻呼第一用户身份或第二用户身份的寻呼消息之后，或者其他的能够获知第一PO和第二PO的具体情况的时刻。
具体地，终端设备确定发生PO冲突可以是终端设备确定上述的第一PO和上述的第二PO在时域，或者时域和频域上占用的位置相同或部分重叠。下文简称第一PO和第二PO之间发生PO冲突。
为了更形象地理解PO冲突，结合图5说明如何判定是否发生PO冲突。图5是本申请实施例提供的发生PO冲突的示意性框图。从图5的(a)中可以看出，系统帧#1中第一PO和系统帧#2中第二PO部分重叠，则第一PO和第二PO发生PO冲突；从图5的(b)中可以看出，系统帧#1中第一PO和系统帧#2中第二PO全部重叠，则认为第一PO和第二PO发生PO冲突。应理解图5中所示的发生PO冲突的情况只是举例，对本申请的保护范围不够成任何限定。终端设备如何确定发生PO冲突可以参考目前协议的规定或未来协议中的规定，本申请对此不再赘述。
进一步地，终端设备以上述的第一用户身份处于非活动态，本申请所涉及的非活动态可以指的是NR通信协议中规定的RRC_INACTIVE态，又可以指的是LTE通信协议中规定的增强的RRC_IDLE态，比如可以进行RRC恢复的RRC_IDLE态，或者可以指未来通信系统中的具有相似功能的状态。本申请实施例只是以NR系统中的信令流程进行举例描 述，对本申请的保护范围并不限定。
作为一种可能的实现方式，在第一用户身份处于非活动态之前，图4所示的方法流程还包括S411：终端设备接收第二接入网设备发送的第一消息。具体地，该第一消息可以为无线资源控制释放(radio resource control release，RRC release)消息，该第一消息中包括挂起配置，该挂起配置包括终端设备进入RRC_INACTIVE态的配置信息。终端设备接收到第一消息之后，上述的第一用户身份进入RRC_INACTIVE态。
应理解，本申请实施例中对于终端设备支持的第二用户身份所处的状态并不限制，可以是RRC_IDLE态、RRC_INACTIVE态、或RRC_CONNECTED态。在第二用户身份处于RRC_IDLE态或RRC_INACTIVE态的情况下，本申请实施例提供的寻呼的方法，在避免PO冲突的前提下还可以提高更新参数的速度，因为本申请实施例提供的寻呼的方法是通过处于INACTIVE态的第一用户身份发起的参数更新流程。
该实施例中终端设备确定发生PO冲突之后，将该冲突通知给当前服务小区(又可以称为第一小区)所属的第一接入网设备，则图4所示的方法流程还包括S420：终端设备向第一接入网设备发送第一指示信息，该第一指示信息用于指示上述的第一寻呼时机和第二寻呼时机发生冲突。
作为一种可能的实现方式，终端设备向第一接入网设备发送指示所述第一寻呼时机和所述第二寻呼时机冲突的第一指示信息可以是：终端设备向第一接入网设备发送第一请求消息，该第一请求消息中包括该第一指示信息。其中，第一请求消息可以为RRC恢复请求(RRC resume request)消息或其他携带第一指示信息的消息。
作为另一种可能的实现方式，终端设备向第一接入网设备发送指示所述第一寻呼时机和所述第二寻呼时机冲突的第一指示信息可以是终端设备和第一接入网设备之间新增的信令。
可选的，从节约信令开销的角度考虑，上述的第一指示信息可以携带在RRC resume request消息中发送给第一接入网设备。一种可能的实现方式中，从第一指示信息的功能(用于指示第一寻呼时机和第二寻呼时机冲突)触发，可以将第一指示信息称为原因值(cause)。作为一种可能的实现方式，原因值可以为PO冲突(PO collision)。
该实施例中第一接入网设备获知发生PO冲突之后，可以向第二接入网设备发送第二指示信息，通知第二接入网设备第一用户身份和第二用户身份在上述的第一小区发生PO冲突，则图4所示的方法流程还包括S430：第一接入网设备向第二接入网设备发送第二指示信息，该第二指示信息用于指示上述的第一寻呼时机和第二寻呼时机发生冲突。
作为一种可能的实现方式，第一接入网设备向第二接入网设备发送第二指示信息可以是，第一接入网设备向第二接入网设备发送第二请求消息，该第二请求消息中包括该第二指示信息。其中，第二请求消息可以为获取终端设备上下文请求(retrieve UE context request)消息或其他携带第二指示信息的消息。
作为另一种可能的实现方式，第一接入网设备向第二接入网设备发送第二指示信息可以是第二接入网设备和第一接入网设备之间新增的信令。
可选地，第二指示信息包括如下信息的至少一种：第一指示信息、上述的第一小区的寻呼配置信息、或第二参数。
其中，第一指示信息为上述的第一指示信息，这里不再赘述。第一小区的寻呼配置信 息包括缺省寻呼周期内的寻呼帧的个数和一个寻呼帧内的寻呼时机的个数。进一步地，第一小区的寻呼配置还可以包括第一小区的缺省寻呼周期、终端设备的无线接入网寻呼周期、或第一小区的寻呼帧偏移量的至少一种。第二参数为第一接入网设备生成的用于计算第三寻呼时机的参数，可以为第二接入网设备计算第一参数提供参考。
该实施例中第二接入网设备接收到上述的第二指示信息之后，验证终端设备，即图4所示的方法流程还包括S431：第二接入网设备验证终端设备。本申请中第二接入网设备为保存有终端设备上下文的接入网设备，可以通过终端设备的安全上下文对终端设备进行验证。
第二接入网设备验证终端设备成功之后，确定发生PO冲突，则第二接入网设备可以生成用于计算第一用户身份对应的第三PO的第一参数，则图4所示的方法流程还包括S440：第二接入网设备生成第一参数。
上述的第三PO与上述的第二PO不重叠，能够避免发生PO冲突。图6是本申请实施例提供的一种未发生PO冲突的示意性框图。从图6中可以看出，系统帧#1中第三PO和系统帧#2中第二PO不重叠。其中，第三PO可以根据第一参数确定(应理解，第一参数与确定第一PO的参数全部或者部分不同)，具体地，有前文所述的PO计算可知第一参数包括寻呼帧偏置、寻呼时机偏置、用户标识、或不连续接收配置中的至少一种。用户标识可以是更新后的S-TMSI mod 1024或IMSI mod 1024，或者相对于原有的S-TMSI mod 1024的变换量，称为S-TMSI mod 1024_offset，或者相对于原有的IMSI mod 1024的变换量，称为IMSI mod 1024_offset，或者其它可以识别终端设备的标识或者相对于原有其它可以识别终端设备的标识的变换量。作为一种示例，若标识可以是更新后的S-TMSI mod 1024或IMSI mod 1024，基于用户标识确定第三PO可以为直接根据更新后的S-TMSI mod 1024或IMSI mod 1024计算第三PO；若用户标识为S-TMSI mod 1024_offset(或者，IMSI mod 1024_offset)，基于用户标识确定第三PO可以为根据原有的S-TMSI mod 1024和S-TMSI mod 1024(或者，根据原有的IMSI mod 1024和IMSI mod 1024_offset)计算第三PO。应理解，本申请实施例中对于用于计算第三PO的第一参数具体包括的参数并不限制，可以参考目前协议中规定的计算PO所需的参数或未来协议中对于计算PO所需参数的规定。还应理解，本申请实施例中涉及的偏置指的是“offset”，可以译为偏置还可以译为偏差，本申请对此并不限制。
作为一种可能的实现方式，当上述的第二指示信息中包括上述的第一小区的寻呼配置信息时，第二接入网设备可以根据第一小区的寻呼配置信息确定终端设备在第一小区中的PF和PO，从而基于第一小区的寻呼配置生成第一参数；
作为另一种可能的实现方式，当上述的第二指示信息中未携带第一小区的寻呼配置信息时，第二接入网设备也可以生成第一参数，通过改动PF和PO计算公式中的任一参数可以生成第一参数，比如改动用于计算PO的寻呼帧偏置、寻呼时机偏置、用户标识、或不连续接收配置中的至少一种。
可选地，该实施例中第二接入网设备生成第一参数之后可以保存该第一参数，则图4所示的方法流程还包括S441：第二接入网设备保存第一参数。
可选的，第二接入网设备还可以保存第一参数对应的小区信息和终端设备的标识。其中，小区信息可以包括小区全球标识(cell global identifier，CGI)或者小区标识(cell  identifier)，终端设备的标识可以为终端设备的I-RNTI、S-TMSI、IMSI或其他可以标识终端设备的标识的至少一种。在第二接入网设备保存有第一参数的情况下，后续若第二接入网设备寻呼第一接入网设备下的INACTIVE态终端设备，第二接入网设备可以在向第一接入网设备发RAN paging时包括第一参数，即可选地，图4所示的方法流程还包括S4411：第二接入网设备向第一接入网设备发送第一寻呼消息，该第一寻呼消息中包括上述的第一参数。该第一寻呼消息中还可以包括适用该第一参数的小区信息。小区信息可以包括CGI或者小区标识。

作为另一种可能的实现方式，第二接入网设备向第一接入网设备发送的第一参数可以是第二接入网设备和第一接入网设备之间新增的信令，用于传输第一参数。
具体地，上述第一参数包括的内容可以是以下几种可能中的任意一种：
可能一、第二接入网设备向第一接入网设备发送的第一参数中包括的参数为修改之后的用于计算寻呼时机的参数，第一参数中未包括的用于计算寻呼时机的参数可以使用原有的参数。例如，基于寻呼帧偏置、寻呼时机偏置、用户标识和不连续接收配置计算第三寻呼时机，当第二接入网设备确定只改变不连续接收配置的情况下，第一参数中可以只包括变化之后的不连续接收配置，当终端设备接收到该第一参数之后，能够获知基于原来的寻呼帧偏置、寻呼时机偏置、用户标识和新的不连续接收配置计算第三寻呼时机。
可能二、第二接入网设备向第一接入网设备发送的第一参数中包括全部(修改的和未修改的)的用于计算寻呼时机的参数。例如，基于寻呼帧偏置、寻呼时机偏置、用户标识和不连续接收配置计算第三寻呼时机，当第二接入网设备确定只改变不连续接收配置的情况下，第一参数中可以包括变化之后的不连续接收配置以及原有的寻呼帧偏置、寻呼时机偏置和用户标识。终端设备接收到该第一参数之后，基于第一参数中包括的参数计算第三寻呼时机。
可能三、第二接入网设备向第一接入网设备发送的第一参数中包括的参数为修改之后的参数相对于原有的参数的变化量。例如，基于寻呼帧偏置、寻呼时机偏置、用户标识和不连续接收配置计算第三寻呼时机，当第二接入网设备确定只改变不连续接收配置的情况下，第一参数中可以包括变化之后的不连续接收配置相对于原来的不连续接收配置变化量。终端设备接收到该第一参数之后，基于第一参数中包括的变化量获知变化之后的不连续接收配置，在基于已知的寻呼帧偏置、寻呼时机偏置和用户标识计算第三寻呼时机。
上述可能一～可能三只是以举例的形式说明该实施例中第一参数可能的内容，对本申请的保护范围不构成任何限定，本申请中第一参数中包括的内容以及终端设备或接入网设备已知的参数能够计算出与上述的第二PO不冲突的第三PO即可，第一参数的内容不再一一举例说明。

进一步地，第二接入网设备接收到第二指示信息之后，验证终端设备，由于第二接入网设备中保存有终端设备的上下文，所以第二接入网设备基于终端设备的安全上下文对终端设备进行验证。若第二接入网设备验证终端设备成功，则认为上述的终端设备生成的第一参数为可靠的，即图8所示的方法流程还包括S641：第二接入网设备验证终端设备。
第二接入网设备验证终端设备成功之后，通知第一接入网设备成功接收到上述的第二请求消息，即图8所示的方法流程还包括S650：第二接入网设备向第一接入网设备发送第二响应消息。
方式一，第二响应消息为获取终端设备上下文失败(retrieve UE context failure)消息， 该retrieve UE context failure消息中携带第一响应消息，上述的S650为第二接入网设备向第一接入网设备发送第一响应消息，该第一响应消息为第二接入网设备生成的，即图8所示的方法流程还包括S651：第二接入网设备生成第一响应消息。作为一种可能的实现方式，第一响应消息中携带有上述的第一参数；作为另一种可能的实现方式，第一响应消息中携带有第二确认信息，其中，第二确认信息用于指示接入网设备成功接收到第一参数；可以理解的，第二确认信息用于指示接入网设备会根据第一参数，或者第一参数和第一参数适用的小区信息确定终端设备的寻呼时机；作为又一种可能的实现方式，第一响应消息中携带有上述的第一参数和/或第二确认信息。
在此情况下，可以理解为anchor基站确定不向目标基站提供终端设备的上下文(anchor基站为第二接入网设备)，后续第二接入网设备可以将上述的第一参数发送给核心网设备，即图8所示的方法流程还包括S660：第二接入网设备向核心网设备发送第一通知消息，该第一通知消息中携带有上述的第一参数。可选的，该第一通知消息中还可以包括第一参数对应的小区信息。小区信息可以包括CGI或者小区标识。
进一步地，当第二接入网设备接收到上述的第一参数之后，第二接入网设备可以保存上述的第一参数，即图8所示的方法流程还包括S661：第二接入网设备保存第一参数。可选的，第二接入网设备还可以保存第一参数对应的小区信息和终端设备的标识。小区信息可以包括CGI或者小区标识，终端设备的标识可以为终端设备的I-RNTI、S-TMSI、IMSI或其他可以标识终端设备的标识的至少一种。后续若第二接入网设备寻呼第一接入网设备下的INACTIVE态终端设备，第二接入网设备可以在向第一接入网设备发RAN paging时包括第一参数。可选的，RAN paging中还可以包括第一参数对应的小区信息。
方式二，第二响应消息为获取终端设备上下文响应(retrieve UE context response)消息，该retrieve UE context response消息中携带终端设备的上下文，或者，第二响应消息为retrieve UE context failure消息，但是该retrieve UE context failure消息中携带有生成第一响应消息所需的第三参数上，述的S650为第二接入网设备向第一接入网设备发送终端设备的上下文或第三参数。
在此情况下，第一接入网设备接收到第二响应消息之后可以基于终端设备的上下文或生成第一响应消息所需的第三参数，生成第一响应消息，即图8所示的方法流程还包括S670：第一接入网设备生成第一响应消息。作为一种可能的实现方式，第一响应消息中携带有上述的第一参数；作为另一种可能的实现方式，第一响应消息中携带有第一确认信息，其中，第一确认信息用于指示接入网设备成功接收到第一参数；作为又一种可能的实现方式，第一响应消息中携带有上述的第一参数和/或第一确认信息。
在此情况下，可以理解为anchor基站确定向目标基站提供终端设备的上下文，即anchor基站从第二接入网设备变为第一接入网设备，第一接入网设备成功获得了终端设备的上下文，可以作为anchor基站。后续第一接入网设备可以将上述的第一参数发送给核心网设备，即图8所示的方法流程还包括S671：第一接入网设备向核心网设备发送第二通知消息，该第二通知消息中携带有上述的第一参数。可选的，该第二通知消息中还可以包括第一参数对应的小区信息。小区信息可以包括CGI或者小区标识。
进一步地，当第一接入网设备接收到上述的第一参数之后，第一接入网设备可以保存上述的第一参数，即图8所示的方法流程还包括S632：第一接入网设备保存第一参数。 可选的，第一接入网设备还可以保存第一参数对应的小区信息和终端设备的标识。小区信息可以包括CGI或者小区标识，终端设备的标识可以为终端设备的I-RNTI、S-TMSI、IMSI或其他可以标识终端设备的标识的至少一种。后续若第二接入网设备寻呼第一接入网设备下的INACTIVE态终端设备，第二接入网设备可以在向第一接入网设备发RAN paging时和现有流程一致，无需改动。
作为一种可能的实现方式，上述第二接入网设备向核心网设备发送的第一通知消息或第一接入网设备向核心网设备发送的第二通知消息中还可以包括适用该第一参数的小区信息。
应理解，接入网设备向核心网设备发送通知消息可以避免核心网设备对INACTIVE态终端设备进行CN paging时，由于没有最新的寻呼参数，而造成的核心网设备侧和终端设备侧对PF和PO的理解不一致的问题。
可以理解的，若第一接入网设备包括CU和DU，第一接入网设备的CU向第一接入网设备的DU发送第三寻呼消息，该第三寻呼消息中携带有上述的第一参数。DU可以根据第一参数确定终端设备的寻呼时机，并在该寻呼时间向终端设备发送寻呼消息。可选的，该第三寻呼消息中还可以携带上述的第一参数对应的小区信息。小区信息可以包括CGI或者小区标识。DU可以根据该小区信息确定第一参数适用的小区。
进一步地，在第一接入网设备接收到上述的第二响应消息之后，向终端设备发送第一响应消息，第一响应消息用于指示终端设备发送的第一参数已成功接收，即图8所示的方法流程还包括S680：第一接入网设备向终端设备发送第一响应消息，该第一响应消息用于通知终端设备发送的第一参数已被接入网设备成功接收到。
作为一种可能的实现方式，第一响应消息中携带上述的第一参数；
作为另一种可能的实现方式，第一响应消息中携带第一确认信息，第一确认信息用于指示接入网设备成功接收到第一参数；
作为又一种可能的实现方式，第一响应消息中携带上述的第一参数和/或第一确认信息。
可选地，第一响应消息为RRC释放消息。
作为一种可能的实现方式，上述图4、图7和图8所示的方法流程中，终端设备可以获得第一参数。例如，执行图4中的S444之后，终端设备从第一接入网设备接收到第一参数；还例如，执行图7中的S545之后，终端设备从第一接入网设备接收到第一参数；还例如，执行图8中的S620之后，终端设备生成了第一参数。
进一步地，当终端设备获得了第一参数之后，终端设备可以保存第一参数以及第一参数对应的小区信息。其中，小区信息可以包括CGI或者小区标识。该终端设备还保存有终端设备的标识，终端设备的标识可以为终端设备的I-RNTI、S-TMSI、IMSI或其他可以标识终端设备的标识的至少一种。
应理解，本申请实施例中，终端设备可以仅在第一小区根据第一参数计算第三寻呼时机，当终端设备驻留到其它小区时，若根据原有的参数确定的寻呼时机不冲突，终端设备可以继续使用原有的参数确定寻呼时机。
例如，终端设备的两个用户身份分别驻留在小区1和小区2，终端设备确定在小区1的PO#A和小区2的PO#B冲突，终端设备获取第一参数，根据第一参数确定终端设备在 小区1的新PO#A’。当终端设备以第一用户身份驻留到了小区3，终端设备根据原有的寻呼参数和小区3的寻呼配置参数确定PO#C和PO#B是否发生PO冲突。若不冲突，终端设备根据PO#C进行寻呼消息的接收。若冲突，可以根据本申请实施例提供的方案获取新的参数，根据新的参数确定终端设备在小区3的新PO#C’。
若终端设备以第一用户身份回到小区1，则终端设备根据第一参数确定终端设备在小区1的PO#A’和以第二用户身份所在的小区k的PO#N，确定是否发生PO冲突。若不冲突，终端设备根据PO#A’进行寻呼消息的接收。若冲突，可以根据本申请实施例提供的方案描述获取新的参数，根据新的参数确定终端设备在小区1的新PO#A”。
作为另一种可能的实现方式，终端设备可以在以第一用户身份所在的后续的各小区都根据第一参数确定对应的PO，用于确定是否发生PO冲突。
作为又一种可能的实现方式，若终端设备可以在以第一用户身份所在的后续的各小区都根据原有的参数确定对应的PO。比如当终端设备以第一用户身份回到小区1，则终端设备根据原有的参数确定终端设备在小区1的PO#A和以第二用户身份所在的小区k的PO#N，确定是否发生PO冲突。若不冲突，终端设备向网络设备发送恢复寻呼参数为原有的参数的指示信息。对应的，接入网设备，或者接入网设备和核心网设备都恢复为原有的参数。
