技术领域

背景技术
当前，移动通信系统正在考虑在终端中除了主接收机(或者称之为通信接收机)外，还引入低功耗唤醒接收机。当需要省电时，主接收机进入超深睡眠模式，开启低功耗唤醒接收机来监听唤醒信号(Wake Up Signal，WUS)，当低功耗唤醒接收机监听到唤醒信号后才唤醒主接收机，从而达到节约终端的功耗的目的。在一些相关技术中，无线接入网设备在小区发送唤醒信号，接收到该唤醒信号的所有终端都响应该唤醒信号。例如：接收到该唤醒信号的终端都启动主接收机来监听寻呼消息。然而，在实际应用中，无线接入网设备发送一个唤醒信号往往是发送给某一个终端的，其余终端即使响应该唤醒信号也接收不到自己的寻呼消息，这被称之为虚警。这样的机制导致终端的功耗比较高。

核心网设备可以包含但不限于如下至少一项：核心网节点、核心网功能、移动管理实体(Mobility Management Entity，MME)、接入移动管理功能(Access and Mobility Management Function，AMF)、会话管理功能(Session Management Function，SMF)、用户平面功能(User Plane Function，UPF)、策略控制功能(Policy Control Function，PCF)、策略与计费规则功能单元(Policy and Charging Rules Function，PCRF)、边缘应用服务发现功能(Edge Application Server Discovery Function，EASDF)、统一数据管理(Unified Data Management，UDM)、统一数据仓储(Unified Data Repository，UDR)、归属用户服务器(Home Subscriber Server，HSS)、集中式网络配置(Centralized network configuration，CNC)、网络存储功能(Network Repository Function，NRF)、网络开放功能(Network Exposure Function，NEF)、本地NEF(Local NEF，或L-NEF)、绑定支持功能(Binding Support Function，BSF)、应用功能(Application Function，AF)等。需要说明的是，在本申请实施例中仅以NR系统中的核心网设备为例进行介绍，并不限定核心网设备的具体类型。
在一些实施例中，终端在RRC层有三种状态：空闲态(idle态)、去激活态(inactive态)、连接态(connected态)。
其中，在idle态，终端与无线接入网设备没有建立RRC连接，无线接入网设备没有该终端的RRC上下文。从核心网的角度来看，RAN侧与核心网设备的连接也断开。为了减少耗电，终端在大部分时间处于休眠状态，因此无法进行数据传输。终端可周期性地唤醒以在无线空口从网络接收寻呼消息(如果有的话)。寻呼消息包括终端的临时移动订阅标识(Temporary Mobile Subscription Identifier，TMSI)，例如：对于5G系统来说，可以是5G系统临时移动签约标识(5G S-Temporary Mobile Subscription Identifier，5G-S-TMSI)。5G-S-TMSI长度为48比特。终端的TMSI(例如：5G-S-TMSI)是在该终端向核心网设备注册过程中由核心网设备分配并发送给终端的。当终端收到发给自己的寻呼消息(即寻呼消息中包括该终端的TMSI)后，或者终端有上行数据需要发送，则终端发起随机接入过程并建立RRC连接，从而从idle态转入connected态。Idle态的终端驻留在一个服务小区，随着终端的移动，通过小区重选机制来更换驻留的服务小区。
在connected态，终端与无线接入网设备之间、无线接入网设备与核心网设备之间建立了连接。无线接入网设备为该终端保存了RRC上下文。终端可以与无线接入网设备之间传输上下行数据。在连接态，移动性可由网络侧控制，即用户设备(User Equipment，UE)向网络提供邻小区测量，网络命令设备进行切换(handover)。
在inactive态，终端与无线接入网设备之间的RRC连接被释放，最后一个服务无线接入网设备保存了终端的RRC上下文，并维持与核心网设备的终端连接。Inactive态对核心 网设备是透明的，也就是说，从核心网的角度来看，终端仍处于连接状态。在无线接入网设备使UE进入inactive态时，会在RRC释放(RRC release)消息中给UE分配一个40比特长度的非激活态无线网络临时标识(Inactive Radio Network Temporary Identifier，I-RNTI)和配置一个无线接入网通知区域(RAN-based Notification Area，RNA)，终端可以在RNA区域内的小区之间移动而不用通知网络。因此，当网络需要终端进入connected态时，在RNA区域内的所有小区使用I-RNTI寻呼该终端。从去激活态转换到连接态的速度很快，且不需要核心网信令。同时，允许终端以空闲态类似的方式休眠，并且通过小区重选来处理移动性。因此，inactive态可以被视为空闲和连接状态的混合。
在一些实施例中，上述的RRC状态是终端与无线接入网设备之间的状态。终端与核心网设备(例如：AMF)之间的状态是连接管理(Connection Management，CM)状态，包括：CM-IDLE和CM-CONNECTED两种状态，终端处于CM-IDLE态时，是没有该终端的N2和N3连接的，在空口，对应的终端状态是idle态。处于CM-CONNECTED状态的UE和对应的AMF之间建立了非接入层(Non-Access-Stratum，NAS)信令连接，在空口，对应的终端状态是connected或inactive态。
在一些实施例中，低功耗接收机也可以称作低功耗唤醒接收机(low power wake up radio或low power wake up receiver，LP-WUR)或称为近零功耗接收机(almost zero power wake up radio,AZP-WUR)。LP-WUR的基本工作原理为终端包含第一模块和第二模块，具体如图2所示，第一模块为主通信模块(在本申请实施例中，也称之为主接收机或通信接收机)，用于移动通信数据的收发，第二模块为低功耗接收模块(在本申请实施例中，也称低功耗唤醒接收模块或者WUR接收机)，用于接收唤醒信号。终端在节能状态下开启低功耗接收模块来监听LP-WUS(在本申请实施例中，也称之为WUS)且关闭主通信模块。当有下行数据到达时，网络会发送唤醒信号给终端，终端通过低功耗接收模块监听到唤醒信号后通过一系列的判断后触发主通信模块从关闭到开启，而此时低功耗接收模块从工作态进入关闭状态。低功耗唤醒接收模块可以连续开启，或间歇性开启，在开启时可接收低功耗唤醒信号。
在一些实施例中，为了减少终端在待机状态下的接收活动，使得射频(Radio Frequency，RF)和基带(MODEM)模块真正的关闭从而大大降低通信接收的功耗，可以通过在终端的接收模块中引入一个近“零”功率的接收机而实现。这个近“零”功率的接收机不需要复杂的RF模块的信号检测(如放大、滤波、量化等等)和MODEM的信号处理，只靠被动的匹配滤波和较小功耗的信号处理。
在一些实施例中，在无线接入网设备侧，通过按需(on-demand)触发唤醒信号，就可以激活近“零”功率的接收机获知激活的通告，从而触发终端内部的一系列流程，例如，打开射频收发以及基带处理等模块。
在一些实施例中，唤醒信号可以是一些比较简单的开关键控信号(on-off keying)，开关键控信号的时域样式，可以如图3所示，那样接收机就可以通过简单的能量检测，以及 之后的可能的序列检测识别等过程获知唤醒通告。此外，在终端开启低功耗唤醒接收机来接收唤醒信号的同时，主接收机模块可以维持在一个较低耗电水平下工作，从而通过接收唤醒信号来实现功耗节省。
在一些实施例中，唤醒信号可以携带少量的有效载荷，比如10比特的信息。
在一些实施例中，唤醒信号的接收可以应用于处idle/inactive状态的终端，也可以应用于处于connected状态的终端，从而实现终端节能。
需要说明的是，上述描述多个实施例中的内容以是5G系统进行举例说明，本申请实施例中对此不作相应限定。
下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的在一些实施例中，进行详细地说明。
请参见图4，图4是本申请实施例提供的一种通信方法的流程图，如图4所示，包括以下步骤：
步骤401、终端接收来自于无线接入网设备的RRC释放消息，所述RRC释放消息包括唤醒终端标识。
该步骤可以是终端在connected态时，接收无线接入网设备发送的RRC释放消息，该RRC释放消息指示终端进入idle态。
其中，所述唤醒终端标识为：所述无线接入网设备为所述终端分配的在唤醒信号区域内具备唯一性的终端标识。
上述唤醒终端标识可以是，唤醒信号终端标识(WUS UE ID)。
上述唤醒信号区域(WUS area)可以是无线接入网设备分配的区域，或者可以是核心网设备确定的区域，或者是一个默认的区域，比如总是当前服务小区或当前服务小区归属的TA或WUS area ID所代表的区域。
上述唤醒终端标识为在唤醒信号区域内具备唯一性的终端标识可以是，在唤醒信号区域内的无线接入网设备为每个终端分配的唤醒终端标识不同。也就是说，在上述终端使用该唤醒终端标识期间，在唤醒信号区域范围内只有上述终端使用该唤醒终端标识，该唤醒终端标识在该唤醒信号区域范围内不会被分配给其他终端，直到该唤醒终端标识被释放后才能再次被分配，从而保证了上述终端在唤醒信号区域范围内接收唤醒信号时不会出现虚警，从而减少了不必要的开启主接收机的次数，达到了更加省电的目的。
在一些实施方式中，唤醒终端标识是无线接入网设备给终端分配的用于在接收唤醒信号后进行匹配的终端标识，其不同于无线接入网设备为进入inactive态的终端分配的I-RNTI,也不同于终端的TMSI(例如5G-S-TMSI)。另外，唤醒终端标识长度的设计可以适配唤醒信号能携带的信息长度，可以比TMSI(例如5G-S-TMSI)更短，比如10、15或20bits，从而完整的唤醒终端标识可以放在唤醒信号里携带，解决了过长的TMSI无法放在唤醒信号携带或即使能携带但是由此造成的唤醒信号覆盖范围过小的问题。
步骤402、所述终端进入超深睡眠模式，并监听唤醒信号。
上述超深睡眠模式可以是终端的主接收机或通信接收机进入的超深睡眠模式，或者，上述超深睡眠模式可以是，关闭终端的主接收机或通信接收机的模式。在本申请中，超深睡眠模式也可以称之为超深睡眠功率状态。
上述监听唤醒信号可以是通过低功耗唤醒信号接收机监听唤醒信号。
步骤403、所述终端接收唤醒信号。
上述接收唤醒信号，可以是在监听到唤醒信号的情况下，接收监听到的唤醒信号，即将监听到的唤醒信号接收下来。
需要说明的是，上述唤醒信号可以是上述步骤401中的无线接入网设备发送的，也可以是其他无线接入网设备发送的，比如唤醒信号区域范围内的其他无线接入网设备发送的。
步骤404、在接收到的唤醒信号与所述唤醒终端标识关联的情况下，所述终端响应所述唤醒信号。
上述唤醒信号与所述唤醒终端标识关联可以是，唤醒信号携带的唤醒终端标识与上述唤醒终端标识匹配，如上述唤醒信号携带有上述唤醒终端标识。例如：唤醒终端标识全部由唤醒信号的载荷(payload)携带，或者，唤醒终端标识的一部分比特由唤醒信号的payload携带，其他比特由唤醒信号序列隐式携带，两者组合成完整的唤醒终端标识。
上述在接收到的唤醒信号与所述唤醒终端标识关联的情况下，所述终端响应所述唤醒信号可以是，只有在接收到的唤醒信号与所述唤醒终端标识关联的情况下，所述终端才响应所述唤醒信号。另外，在接收到的唤醒信号与唤醒终端标识不关联的情况下，所述终端不响应所述唤醒信号，如继续保持超深睡眠模式。
上述响应唤醒信号，可以是基于该唤醒信号进行唤醒，如启动主接收机或通信接收机，或者说，主接收机或通信接收机退出超深睡眠模式、监听寻呼消息、发起RRC连接建立等。
本申请实施例中，在上述步骤可以实现只有在接收到的唤醒信号与唤醒终端标识关联的情况下，终端才响应所述唤醒信号，降低了虚警发生的概率，从而可以降低终端的功耗。
作为一种可选的实施方式，所述终端进入超深睡眠模式，并监听唤醒信号，包括：
所述终端的主接收机或通信接收机进入超深睡眠模式，或者，关闭所述终端的主接收机或通信接收机；
所述终端的处于开启状态的低功耗唤醒信号接收机监听唤醒信号。
上述通信接收机可以是指终端的主通信接收机，或者称作终端的主通信模块。
其中，上述终端的主接收机或通信接收机进入超深睡眠模式可以是，终端的主接收机或通信接收机进入协议中定义的超深睡眠模式。
其中，上述低功耗唤醒信号接收机也可以是称作低功耗接收模块或者低功耗接收机或者WUR接收机或者WUR。

需要说明的是，本实施例作为与图4或5所示的实施例中对应的核心网设备的实施方式，其具体的实施方式可以参见图4或5所示的实施例的相关说明，以为避免重复说明，本实施例不再赘述。
下面以终端为UE，无线接入网设备为基站为例，通过多个实施例对本申请实施例提供的方法进行举例说明：
实施例一：
本实施例的主要思想是：在基站识别出UE支持WUS或需要进入WUS接收状态后，在让该UE进入idle态时，给该UE分配一个WUS UE ID和WUS area，该WUS UE ID在该WUS area范围内唯一，在RRC release消息中将分配的WUS UE ID和WUS area发送给该UE。基站维护该UE的5G-S-TMSI与WUS UE ID和WUS area的映射关系，并将该映射关系发送给WUS area范围内的其他基站。在收到核心网设备发送的paging消息后，服务基站和WUS area范围内的其他基站基于映射关系获取到paging消息中携带的5G-S-TMSI关联的WUS UE ID，然后在无线空口发送携带该WUS UE ID的WUS信号。该监听到携带该WUS UE ID的WUS信号后，启动主接收机，UE的接入层(Access-Stratum，AS)层向NAS层指示接收到WUS信号以触发NAS层请求建立RRC连接。
具体可以如图7所示，包括如下步骤：
步骤1：UE进入RRC连接态。UE的服务基站获知该UE是支持WUS或需要进入WUS接收状态以达到终端省电效果的终端。具体获知方法可以如下：
方法1：UE接入能力包括UE是否支持WUS的能力信息，基站从UE或核心网设备获取到UE的接入能力；
方法2：UE进入连接态后，向基站发送UE辅助信息消息(UE Assistance Information)，该消息中包括指示信息，用于指示UE(在进入idle态时)需要进入WUS接收状态以达到终端省电效果(或者说，UE是一个WUS终端)；
方法3：在UE建立与网络连接的过程中，核心网设备(AMF)向服务基站发送指示信息，用于指示UE(在进入idle态时)需要进入WUS接收状态以达到终端省电效果(或者说，UE是一个WUS终端)。具体的，终端在发送给核心网设备的注册请求消息中指示是WUS终端，或者该终端的签约信息中包括WUS终端指示，在核心网设备发送给服务基站的初始上下文建立请求消息(Initial Context Setup Request)中携带指示信息用于指示UE(在进入idle态时)需要进入WUS接收状态以达到终端省电效果(或者说，UE是一个WUS终端)。
步骤2：服务基站决定让UE进入idle态。比如：当不活动定时器超时后，服务基站决定让UE进入idle态。服务基站为该UE分配WUS UE ID和WUS area，该WUS UE ID在该WUS area范围内唯一，也就是说，在该UE使用该WUS UE ID期间，在WUS area范围内只有该UE使用该WUS UE ID，该WUS UE ID在该WUS area范围内不会被分配给其他UE，直到该WUS UE ID被释放后才能再次被分配，从而保证了该UE在WUS area范围内接收WUS信号时不会出现虚警，从而减少了不必要的开启主接收机的次数，达到了更加省电的目的，具体参见步骤13/14相关的描述。
在一些实施方式中，为确保WUS area范围内的多个基站各自分配的WUS UE ID不冲 突(即不相同)，可以通过以下方式实现：比如运营商规划各个基站能分配的WUS UE ID范围，各个基站能分配的范围不重叠；或者标准协议规定WUS UE ID的部分比特用于携带基站索引，WUS area范围内基站的基站索引不相同。
WUS area可以是如下至少一项：
一个小区ID列表；
一个TA(Tracking Area)列表；
一个WUS area ID或WUS area ID列表，即每个小区可以被配置一个WUS area ID，多个小区可以配置相同或不同的WUS area ID；
一个beacon(或同步)信号(比如，beacon序列)或beacon(或同步)信号列表。
WUS area也可以被限定是一个默认的区域，比如总是当前服务小区或当前服务小区的TA或WUS area ID，此时可以没有服务基站为该UE分配WUS area的操作。
WUS area可以是在该UE的注册区域范围内。
可选的，在本实施例中，假定WUS UE除了监听WUS信号外，还监听beacon信号或同步信号，beacon信号或同步信号可以被周期性发送。如果UE能监听到列表中的beacon或同步信号(比如，高于一定阈值)，则认为在WUS area内，否则认为移出WUS area；或者，该beacon或同步信号中携带小区ID信息或WUS area ID或TA，如果UE监听到的beacon或同步信号携带的值在WUS area内(对应的小区ID列表或WUS area ID列表或TA列表)，则认为还在范围内，否则认为移出了WUS area。
需要说明的是，WUS UE ID是基站给UE分配的用于在接收WUS信号后进行匹配的UE ID，其不同于基站为进入inactive态的UE分配的I-RNTI,也不同于UE的5G-S-TMSI。WUS UE ID长度的设计可以适配WUS信号能携带的信息长度，可以比5G-S-TMSI更短，比如20bits，从而可以被携带在步骤13/14的WUS信号里发送。
步骤3：服务基站维护该UE的5G-S-TMSI与WUS UE ID和WUS area的映射关系。即该UE的5G-S-TMSI与WUS UE ID和WUS area的映射关系不是放在该UE的UE上下文中，而是，比如服务基站维护一个全局变量表(在该UE的UE上下文之外)，将该映射关系放在这个全局变量表里。该全局变量表存放各个UE的5G-S-TMSI与WUS UE ID和WUS area的映射关系。即使该UE的UE上下文在步骤4中被释放，这个映射关系仍然被维护。
比如：服务基站内部维护如图4所示的实施例中表1所示的一个全局的映射关系表。
在执行该步骤3时，将该UE的映射关系加入到上述表中。
其中，5G-S-TMSI是在连接建立过程中从终端或核心网设备获取到的，并保存在该UE的UE上下文中，在该UE的UE上下文被释放之前，从中获取到该UE的5G-S-TMSI。
可选的，也维护分配该WUS UE ID的基站信息，即在该步骤中为服务基站信息(从而与步骤7中的映射关系表的结构保持一致)。
步骤4：服务基站向该UE发送RRC Release消息，使UE进入idle态。服务基站释放 该UE的UE上下文。该RRC Release消息中携带给该UE分配的WUS UE ID，可选的，还携带分配的对应的WUS area信息。比如，如果在步骤2中。WUS area被限定是一个默认的区域，则在该步骤中，可以不携带WUS area信息，否则还携带分配的对应的WUS area信息。该UE在服务基站里的UE上下文被释放。
需要说明的是，步骤3与步骤4的执行顺序不做限定。即也可以先执行步骤4，再执行步骤3。
步骤5：服务基站向WUS area范围内的(所有的)邻接基站发送第一消息，该第一消息用于指示邻接基站增加一个5G-S-TMSI与WUS UE ID和WUS area的映射关系，该第一消息包括该UE的5G-S-TMSI、WUS UE ID和WUS area。
该第一消息可以是非UE关联的NGAP消息，比如新增一个NGAP消息，称之为映射关系建立消息，消息名称不做限定。
步骤6：UE在收到RRC release消息后进入idle态，保存该WUS UE ID和WUS area。UE关闭主接收机(或者说，主接收机进入超深度睡眠ultra-deep sleep)，开启WUR接收机以在WUS area范围内监听携带该WUS UE ID的WUS信号。可选的，也监听beacon或同步信号，以判断是否移出了配置的WUS area范围。当该UE移出WUS area范围后，具体操作可以参见实施例四。
可选的，当UE在WUS area范围内移动时，或者说，当UE在关闭了主接收机而只开启WUR接收机的状态时，UE可以被认为不驻留在任何一个小区(没有小区驻留概念)，或者说，驻留在该WUS area范围。当UE在WUS area范围内移动时，UE不执行小区重选操作，不需要获取小区的系统信息，甚至网络和UE不知道自己在哪个小区，只进行WUS信号监听和判断是否移出WUS area范围。
步骤7：邻接基站收到第一消息后，维护该5G-S-TMSI与WUS UE ID和WUS area的映射关系。比如，类似于步骤3，在该邻接基站维护一个全局变量表，该变量表存放各个UE的5G-S-TMSI与WUS UE ID和WUS area的映射关系。在收到第一消息后，将该5G-S-TMSI与WUS UE ID和WUS area的映射关系加入到上述表中。
可选的，该变量表中还保存发送第一消息的基站信息，也就是图中的服务基站信息，或者说分配该WUS UE ID的基站信息，在实施例四中可能使用。
可选的，邻接基站向服务基站发送响应消息。
步骤8(可选步骤)：该UE移动到WUS area范围内的另一个基站下。
步骤9-10：在该UE的下行数据到达，或者核心网设备需要向该UE发送信令等情况下，核心网设备需要寻呼该UE进入连接态。根据协议定义的机制，核心网设备可以向注册区域范围内的所有基站发送NGAP消息paging，其中包括服务基站和WUS area内邻接基站，该paging消息中携带该UE的5G-S-TMSI和注册区域信息(TA list)。
步骤11-12：接收到核心网设备发送的paging消息的基站在映射关系表中查找是否存在该5G-S-TMSI的映射关系。如果存在(对于该UE的WUS area范围内的基站，则存在， 否则不存在)，则基于映射关系获取到5G-S-TMSI关联的WUS UE ID和WUS area，从而在步骤13-14中在WUS信号中发送该WUS UE ID。如果不存在(即在该UE的注册区域内但是WUS area范围外的基站)，由于没有查找到该5G-S-TMSI的映射关系，则采用协议定义的机制，即在空口发送paging消息。
步骤13/14：查找到存在该5G-S-TMSI的映射关系的基站(即服务基站和WUS area范围内的邻接基站)在无线空口发送WUS信号，具体的，一个基站下可能包括多个小区，这多个小区可能部分属于该WUS area，另一部分不属于，在该步骤中，在该基站下的位于注册区域内且也位于WUS area范围内的小区上发送WUS信号，在该基站下的位于注册区域内，但不位于WUS area范围内的小区上发送paging消息，在该基站下的不位于注册区域的小区上什么也不发送。
该WUS信号中携带该(如完整的)WUS UE ID，WUS UE ID可以全部由payload携带，也可以是一部分bits由payload携带，其他由WUS序列隐式携带，两者组合成完整的WUS UE ID。
需要说明的是，在协议定义的一些机制中寻呼消息中的UE ID类型是5G-S-TMSI，其长度为48bits，WUS接收机可能无法携带这么长的有效负荷(payload)，比如只能携带20bits，一些方法可以是携带分组信息，比如5G-S-TMSI的部分bits，即使该UE能匹配WUS信号的分组信息，也不能最终确认自己被寻呼，有可能是发给该组的其他UE的(此时即为虚警)，该UE需要开启主接收机接收paging消息以后才能最终确定是否自己被寻呼。一方面，需要UE再接收paging进行确认，即使最终确认是自己被寻呼，也增加了接入时延，另一方面，如果最终确定不是自己被寻呼，则该UE由于不必要的开启主接收机而费电。而在该步骤中，该WUS UE ID是基站分配的，能被完整携带在WUS信号中，且在WUS area范围内唯一。因此可以避免虚警，起到了省电和节省时延的作用。
可选的，在发送WUS信号的小区上，也发送paging消息，以增加健壮性。
步骤15：UE监听到携带该WUS UE ID的WUS信号，启动主接收机。
一种方法是：不再接收paging消息(以减少时延)，而是直接发起RRC连接建立过程，具体的可以是，UE的AS层向UE的NAS层指示接收到WUS信号以触发NAS层请求AS层建立RRC连接；
另一种方法是：继续接收paging消息(以增加健壮性)，在确认paging消息中携带该UE的5G-S-TMSI后发起RRC连接建立过程，具体的可以是，UE的AS层向UE的NAS层指示接收到paging以触发NAS层请求AS层建立RRC连接。
实施例二：
本实施例的主要思想是：不同于实施例一的是，分配WUS UE ID的基站(服务基站)维护该UE的5G-S-TMSI与WUS UE ID和WUS area的映射关系，不将该映射关系发送给WUS area范围内的其他基站。在该服务基站收到核心网设备发送的paging消息后，基于映射关系获取到5G-S-TMSI关联的WUS UE ID和WUS area，然后服务基站向该WUS area 范围内的其他基站发送WUS paging消息，该消息中携带该WUS UE ID和WUS area。邻接基站收到后，在WUS area范围内的小区发送携带该WUS UE ID的WUS信号。可选的，核心网设备只向服务基站发送paging，而不再向注册区域内的其他基站发送paging，从而节省空口寻呼资源，或者核心网设备仍向注册区域内的所有基站发送paging，以避免增加核心网设备的复杂度。
具体可以如图8所示，包括如下步骤：
步骤1-3：同实施例一的步骤1-3。
步骤4(可选步骤)：该UE的服务基站向核心网设备发送第二消息，该第二消息或第二消息包括的指示信息(比如寻呼指示信息)用于指示CN寻呼只需要发送给该服务基站，或指示该UE进入关闭主接收机(开启WUS接收机)状态，从而使得核心网设备在需要发送paging消息时，只需要发送给该基站(而不需要发送给该UE的注册区域内的所有基站)，从而节省寻呼资源。
该第二消息可以是一个新引入的NGAP消息，也可以是协议中已定义的NGAP消息，比如UE上下文释放请求消息或者UE上下文释放完成消息。
步骤5：同实施例一的步骤4。
步骤6：同实施例一的步骤6。
步骤7：同实施例一的步骤8。
步骤8：在该UE的下行数据到达，或者核心网设备需要向该UE发送信令等情况下，核心网设备需要寻呼该UE进入连接态态。有两种方法：
方法1：核心网设备根据第二消息或第二消息包括的指示信息，或者基于该UE为WUS UE或支持WUS的UE(根据签约信息或注册请求获知)，则只向服务基站(比如核心网设备的UE上下文保存的当前的服务基站)发送寻呼消息，而不再向注册区域内的其他基站发送paging，从而节省空口寻呼资源。即不执行步骤13和14。
方法2：使用协议中已定义的机制，核心网设备向注册区域范围内的所有基站发送NGAP消息paging，其中包括服务基站和WUS area内邻接基站，以避免改动核心网设备机制，增加核心网设备的复杂度。这些基站收到后，在空口发送paging消息，即执行步骤13、14和15.
该paging消息中携带该UE的5G-S-TMSI和注册区域信息(TA list)。
步骤9：接收到核心网设备发送的paging消息的基站在映射关系表中查找是否存在该5G-S-TMSI的映射关系。如果存在(对于该UE在进入idle态时的服务基站，则存在，否则不存在)，则基于映射关系获取到5G-S-TMSI关联的WUS UE ID和WUS area，然后执行后续步骤；如果不存在，则采用协议中已定义的机制，即在空口发送paging消息，流程结束。
步骤10：查找到存在该5G-S-TMSI的映射关系的基站(即服务基站)向WUS area范围内的(所有的)邻接基站发送第三消息，该第三消息用于指示邻接基站发送包括该WUS UE ID的WUS信号，该第三消息包括该WUS UE ID和WUS area，可选的，第三消息也可 以包括该UE的5G-S-TMSI和注册区域信息。
该第三消息可以是一个新引入的非UE关联的XnAP消息，比如WUS paging消息(消息名不做限定)，也可以重用协议中已定义的XnAP消息RAN paging，在该消息中新增信元用于携带WUS UE ID和WUS area。
步骤11和12：服务基站和收到第三消息的邻接基站分别在无线空口发送WUS信号，具体的，一个基站下可能包括多个小区，这多个小区可能部分属于该WUS area，另一部分不属于，在该步骤中，在该基站下的位于WUS area范围内的小区上发送WUS信号，或者，在该基站下的位于注册区域范围内且位于WUS area范围内的小区上发送WUS信号。
该WUS信号中携带该(完整的)WUS UE ID，WUS UE ID可以全部由payload携带，也可以是一部分bits由payload携带，其他由WUS序列隐式携带，两者组合成完整的WUS UE ID。
需要说明的是，协议已定义的机制中寻呼消息中的UE ID类型是5G-S-TMSI，其长度为48bits，WUS接收机可能无法携带这么长的有效负荷(payload)，比如只能携带20bits，相关技术中的方法是携带分组信息，比如5G-S-TMSI的部分bits，即使该UE能匹配WUS信号的分组信息，也不能最终确认自己被寻呼，有可能是发给该组的其他UE的(此时即为虚警)，该UE需要开启主接收机接收paging消息以后才能最终确定是否自己被寻呼。一方面，需要UE再接收paging进行确认，即使最终确认是自己被寻呼，也增加了接入时延，另一方面，如果最终确定不是自己被寻呼，则该UE由于不必要的开启主接收机而费电。而在该步骤中，该WUS UE ID是基站分配的，能被完整携带在WUS信号中，且在WUS area范围内唯一。因此可以避免虚警，起到了省电和节省时延的作用。
步骤13、14和15(可选步骤)：对应于步骤8中的方法2，即如果核心网设备向注册区域范围内的所有基站发送NGAP消息paging，则服务基站和WUS area内邻接基站收到该paging消息后，在空口发送携带5G-S-TMSI的paging消息。
步骤16：同实施例一中的步骤15。
实施例三：
本实施例的主要思想是：实施例一和实施例二是基站维护映射关系，不同于实施例一和实施例二的是，在该实施例中，服务基站将分配的WUS UE ID和WUS area发送给核心网设备，核心网设备将其保存在该UE的UE上下文中。当核心网设备需要寻呼该UE时，向WUS area范围内(优选)或注册区域范围内的所有基站发送寻呼消息，寻呼消息中携带该UE的WUS UE ID和WUS area。WUS area范围内的基站在无线空口发送携带该WUS UE ID的WUS信号。
具体可以如图9所示，包括如下步骤：
步骤1-2：同实施例一的步骤1-2.
步骤3：该UE的服务基站向核心网设备发送第四消息，该第四消息包括服务基站分配的该UE的WUS UE ID和WUS area。
该第四消息可以是一个新引入的NGAP消息，也可以是相关技术中的NGAP消息，比如UE上下文释放请求消息或者UE上下文释放完成消息。
步骤4：核心网设备将接收到的WUS UE ID和WUS area保存到该UE的UE上下文中。
步骤5-7：同实施例一的步骤4、6、8
步骤8-9：在该UE的下行数据到达，或者核心网设备需要向该UE发送信令等情况下，核心网设备需要寻呼该UE进入连接态。核心网设备根据该UE的UE上下文获取到该UE的WUS UE ID和WUS area，核心网设备向基站发送寻呼消息，有两种方法：
方法1：核心网设备向该WUS area范围内的所有基站发送寻呼消息。由于WUS area一般比注册区域小，相比于方法2，节省了寻呼资源。
方法2：核心网设备向注册区域范围内的所有基站发送寻呼消息。相比于方法1，改动少，健壮性更好。
该寻呼消息包括该UE的WUS UE ID和WUS area。
需要说明的是，该步骤中的寻呼消息可以是一个新引入的消息，用于指示基站在空口发送携带WUS UE ID的WUS信号，也可以是重用协议中已定义的NGAP消息paging，在协议中已定义的paging消息中引入新的信元携带WUS UE ID和WUS area。
可选的，该寻呼消息也可以携带5G-S-TMSI和TA list。
步骤10-11：接收到核心网设备发送的包括WUS UE ID的寻呼消息的基站(比如，服务基站和WUS area范围内的邻接基站)，确定需要在无线空口发送WUS信号。
需要说明的是，对应于步骤8-9的方法2，有可能接收到包括WUS UE ID的寻呼消息的基站发现该基站下不存在小区处于WUS area范围内，则该基站可以确定不发送WUS信号，而是在无线空口发送携带5G-S-TMSI的paging消息或什么都不发送。
步骤12-13：服务基站和WUS area范围内的邻接基站在无线空口发送WUS信号，具体的，一个基站下可能包括多个小区，这多个小区可能部分属于该WUS area，另一部分不属于，在该步骤中，在该基站下的位于WUS area范围内的小区上发送WUS信号，或者在该基站下的位于注册区域内且也位于WUS area范围内的小区上发送WUS信号。可选的，在该基站下的位于注册区域内但不位于WUS area范围内的小区上发送paging消息或什么都不发送，在该基站下的不位于注册区域的小区上什么也不发送。
该WUS信号中携带该(完整的)WUS UE ID，WUS UE ID可以全部由payload携带，也可以是一部分bits由payload携带，其他由WUS序列隐式携带，两者组合成完整的WUS UE ID。
需要说明的是，协议已定义的机制中寻呼消息中的UE ID类型是5G-S-TMSI，其长度为48bits，WUS接收机可能无法携带这么长的有效负荷(payload)，比如只能携带20bits，相关技术中的方法是携带分组信息，比如5G-S-TMSI的部分bits，即使该UE能匹配WUS信号的分组信息，也不能最终确认自己被寻呼，有可能是发给该组的其他UE的(此时即为虚警)，该UE需要开启主接收机接收paging消息以后才能最终确定是否自己被寻呼。一方 面，需要UE再接收paging进行确认，即使最终确认是自己被寻呼，也增加了接入时延，另一方面，如果最终确定不是自己被寻呼，则该UE由于不必要的开启主接收机而费电。而在本申请实施例该步骤中，该WUS UE ID是基站分配的，能被完整携带在WUS信号中，且在WUS area范围内唯一。因此可以避免虚警，起到了省电和节省时延的作用。
可选的，在发送WUS信号的小区上，也发送paging消息，以增加健壮性。
步骤14-15(可选步骤)：在发送WUS信号的小区上，也发送paging消息，以增加健壮性。
步骤16：同实施例一的步骤15.
实施例四：
本实施例的主要思想是：对实施例一和实施例二进行补充，是关于在UE进入连接态的情况下，如何释放映射关系的方案，以避免分配的WUS UE ID被挂死。具体的，在UE建立RRC连接期间或之后，UE向当前的服务基站或核心网设备发送指示信息，用于指示，比如WUS UE进入了连接态。当前服务基站或核心网设备向原服务基站(分配WUS UE ID的基站)发送指示信息，从而触发原服务基站释放映射关系的操作。
具体可以如图10所示，包括如下步骤：
步骤1：同实施例一中的步骤6.
步骤2(可选步骤)：同实施例一中的步骤8.
步骤3：UE需要建立与网络的连接，比如当接收到匹配自己的WUS UE ID的WUS信号，或该UE有上行数据需要发送，或第一定时器超时，或该UE判断移出了WUS area范围。
第一定时器可以是在步骤1时UE启动的定时器，该第一定时器的时长为WUS UE允许关闭主接收机的最长时间，在UE建立与网络连接后被停止，该第一定时器超时后触发UE建立与网络连接，从而避免该UE由于异常而失联。第一定时器的时长可以较长，比如几十分钟或数小时等。
步骤4：UE开启主接收机，发起RRC连接建立过程以进入连接态。具体的可以是，UE开启主接收机，先执行小区选择过程以驻留在一个适合的小区，然后获取该小区的系统信息，在该小区发起RRC连接建立过程以进入连接态。
有两种方法可以触发原服务基站删除该UE的5G-S-TMSI与WUS UE ID的映射关系，分别对应步骤5a/6a和步骤5b/6b.
步骤5a：UE向当前的服务基站(即步骤4中发起RRC连接建立过程的服务基站)发送第一指示信息，用于指示，比如WUS UE进入了连接态，第一指示信息包括原服务基站信息。
原服务基站是在步骤1之前分配WUS UE ID并让UE进入idle态的基站。
原服务基站信息是能确定原服务基站的信息，可以是原服务基站的ID，或原服务小区的CGI，或WUS UE ID(比如WUS UE ID的部分比特为原服务基站的基站ID或索引)。原 服务小区，可以是终端最近一次接收RRC释放消息时的服务小区。
可选的，第一指示信息还包括该UE的5G-S-TMSI和/或WUS UE ID。
需要说明的是，第一指示信息可以是在步骤4的RRC连接建立过程中，比如在RRC连接建立完成消息中携带，也可以在RRC连接建立过程之后的一个RRC消息中携带。
步骤6a：当前的服务基站基于原服务基站信息确定原服务基站，向原服务基站发送第二指示信息，用于触发原服务基站发起该UE的映射关系删除过程(即触发步骤7和步骤8)，第二指示信息可以用于指示，比如WUS UE进入了连接态，或指示删除映射关系。第二指示信息包括该UE的5G-S-TMSI和/或WUS UE ID。
其中，该UE的5G-S-TMSI可以是从第一指示信息中获取的，也可以是通过RRC连接建立完成消息中获取的。
步骤5b：可选步骤，UE向核心网设备发送第三指示信息，用于指示，比如WUS UE进入了连接态，第三指示信息包括原服务基站信息。
原服务基站是在步骤1之前分配WUS UE ID并让UE进入idle态的基站。
原服务基站信息是能确定原服务基站的信息，可以是原服务基站的ID，或原服务小区的CGI，或WUS UE ID(比如WUS UE ID的部分比特为原服务基站的基站ID或索引)。
可选的，第三指示信息还包括该UE的WUS UE ID。
步骤6b：核心网设备可以在以下情况下确定发送第四指示信息：
在收到第三指示信息后；
或者，在该UE建立与核心网设备的连接时，核心网设备识别出该UE为WUS UE或支持WUS的UE。
核心网设备从第三指示信息或该UE的UE上下文中获取原服务基站信息(UE的上下文中保存原服务基站信息)，从而确定原服务基站，核心网设备向原服务基站发送第四指示信息，用于触发原服务基站发起该UE的映射关系删除过程(即触发步骤7和步骤8)，第四指示信息可以用于指示，比如WUS UE进入了连接态，或指示删除映射关系。第四指示信息包括该UE的5G-S-TMSI和/或WUS UE ID。
可选的，核心网设备从该UE的UE上下文中获取该UE的5G-S-TMSI；
可选的，核心网设备从第三指示信息中获取WUS UE ID；
需要说明的是，当UE的RRC连接被释放时，可以重复上述实施例一至三中的方法，即UE可以在RRC release被分配一个新的WUS UE ID和WUS area，关闭主接收机，开启WUR。
本申请实施例可以实现如下：
基站在决定UE进入idle态时，给该UE分配一个WUS UE ID和WUS area，该WUS UE ID在该WUS area范围内唯一，在RRC release消息中将分配的WUS UE ID和WUS area发送给该UE。
基站维护该UE的5G-S-TMSI与WUS UE ID和WUS area的映射关系，并将该映射关 系发送给WUS area范围内的其他基站。在收到核心网设备发送的paging消息后，服务基站和WUS area范围内的其他基站基于映射关系获取到paging消息中携带的5G-S-TMSI关联的WUS UE ID，然后在无线空口发送携带该WUS UE ID的WUS信号。该监听到携带该WUS UE ID的WUS信号后，启动主接收机，UE的AS层向NAS层指示接收到WUS信号以触发NAS层请求建立RRC连接；或
在该服务基站收到核心网设备发送的paging消息后，基于映射关系获取到5G-S-TMSI关联的WUS UE ID和WUS area，然后服务基站向该WUS area范围内的其他基站发送WUS paging消息，该消息中携带该WUS UE ID和WUS area。邻接基站收到后，在WUS area范围内的小区发送携带该WUS UE ID的WUS信号。可选的，核心网设备只向服务基站发送paging，而不再向注册区域内的其他基站发送paging。
服务基站将分配的WUS UE ID和WUS area发送给核心网设备，核心网设备将其保存在该UE的UE上下文中。当核心网设备需要寻呼该UE时，向WUS area范围内(优选)或注册区域范围内的所有基站发送寻呼消息，寻呼消息中携带该UE的WUS UE ID和WUS area。WUS area范围内的基站在无线空口发送携带该WUS UE ID的WUS信号。
在UE建立RRC连接期间或之后，UE向当前的服务基站或核心网设备发送指示信息，用于指示，比如WUS UE进入了连接态。当前服务基站或核心网设备向原服务基站(分配WUS UE ID的基站)发送指示信息，从而触发原服务基站释放映射关系的操作。
