在一种可能的实施方式中，所述第一信令还用于指示所述第一类型和/或所述第一状态。
在该实施方式中，可由第一核心网设备向第一设备指示第一类型和/或第一状态，从而不必第一设备自行确定第一类型和/或第一状态，减少了第一设备的处理量。
在一种可能的实施方式中，所述第一信令包括如下信息的至少一种：频率信息，所述频率信息用于指示所述第一设备寻呼终端设备的频率；或，次数信息，所述次数信息用于 指示所述第一设备寻呼终端设备的次数；或，准确率信息，所述准确率信息用于指示成功寻呼所述第一设备的终端设备的数量与执行寻呼所述第一设备的终端设备的数量之间的比值；或，数量信息，所述数量信息用于指示预期寻呼所述第一设备的终端设备的数量级；或，寻呼时间信息，所述寻呼时间信息用于指示所述第一设备执行寻呼的开始时间和/或结束时间。

具体实施方式
为了使本申请实施例的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施例作进一步地详细描述。
以下，对本申请实施例中的部分用语或概念进行解释说明，以便于本领域技术人员理 解。
1、本申请实施例中的RFID标签，又可称为电子标签或标签。标签的设计较为简单，是将应用层信令和空口信令融合到一起设计。标签主要基于二进制启闭键控(on-off keying，OOK)进行编解码传输，即，根据数据的幅度调制方式，通过高低电平解码数据。在标签的通信过程中，不支持区分频域和码域，并行性能较差。例如，多个标签要与读写器通信，则可采用时分复用方式，多个标签通过串行过程与读写器通信。标签可以看作是一种终端设备。
另外，射频识别技术又可分为有源、无源和半有源三种。其中，有源射频识别技术下的标签可称为有源标签，其可内置电池，此类标签可以主动向读写器发送信号，无需根据所接收的信号获得用于发送信号的能量。无源射频识别技术下的标签也可称为无源物联网(passive IOT)，即无源的物联网设备，或称为无源标签，此类标签可能并未内置电池等模块，或者电池模块的电量较少，可通过接收的信号获得能量，并通过该能量发送信号。可以理解为，无源标签工作在反射通信场景下，即，无源标签通过反射来自读写器的信号以获取能量，从而传输数据。半有源射频识别技术下的标签，又可称为半有源标签，其集成了有源标签和无源标签的优势，可作为一种特殊的标示物。在平时，此类标签处于休眠状态，可以不工作，不向外界发出信号；只有在进入低频激活器的激活信号范围时，此类标签被激活，则此类标签才开始工作。本申请实施例所涉及的标签，可以是有源标签、无源标签或半有源标签等。
2、本申请实施例中的读写器，是通过手持方式或固定式方式读取(或，写入)标签信息的设备。或者，也可以将读写器理解为是与标签通信的设备。读写器，例如为阅读器(reader)、查询器(interrogator)、扫描器(scanner)、读写器(reader and writer)、读出装置(reading device)或便携式读出器(portable readout device)等。读写器的实现形式可以是终端设备，也可以是接入网设备，例如基站，或者还可以是具有读写功能的设备。
3、本申请实施例中的集成接入回传(integrated access backhaul，IAB)节点(node)/助手(helper)/激励源，可以通过终端设备实现，或者也可以通过接入网设备(例如基站)实现。该IAB节点与标签之间可以进行双向通信；或者，该IAB节点与标签之间也可以只有下行数据，即，该IAB节点能够向标签发送信息，但标签不能向该IAB节点发送信息。该IAB节点与读写器之间可以进行双向通信，该通信可以通过空口传输，也可以通过有线方式传输。
4、本申请实施例中的终端设备，是一种具有无线收发功能的设备，可以是固定设备、移动设备、手持设备(例如手机)、穿戴设备、车载设备，或内置于上述设备中的无线装置(例如，通信模块，调制解调器，或芯片系统等)。例如标签可能是终端设备中的固定设备或移动设备，或是内置于上述设备中的无线装置。所述终端设备用于连接人、物或机器等，可广泛用于各种场景，例如包括但不限于以下场景：蜂窝通信、设备到设备通信(device-to-device，D2D)、车到一切(vehicle to everything，V2X)、机器到机器/机器类通信(machine-to-machine/machine-type communications，M2M/MTC)、物联网(internet of things，IoT)、虚拟现实(virtual reality，VR)、增强现实(augmented reality，AR)、工业控制(industrial control)、无人驾驶(self driving)、远程医疗(remote medical)、智能电网(smart grid)、智能家具、智能办公、智能穿戴、智能交通，智慧城市(smart city)、无人机、机器人等场景的终端设备。所述终端设备有时可称为用户设备(user equipment，UE)、 终端、接入站、UE站、远方站、无线通信设备、或用户装置等。
5、本申请实施例中的网络设备，例如可以包括接入网设备，和/或核心网设备。所述接入网设备为具有无线收发功能的设备，用于与所述终端设备进行通信。所述接入网设备包括但不限于基站(基站收发信站点(base transceiver station，BTS)，Node B,eNodeB/eNB，或gNodeB/gNB)、收发点(transmission reception point，TRP)，第三代合作伙伴计划(3rd generation partnership project，3GPP)后续演进的基站，无线保真(wireless fidelity，Wi-Fi)系统中的接入节点(access point，AP)，无线中继节点或无线回传节点等。所述基站可以是：宏基站，微基站，微微基站，小站或中继站等。多个基站可以支持同一种接入技术的网络，也可以支持不同接入技术的网络。基站可以包含一个或多个共站或非共站的传输接收点。所述接入网设备还可以是云无线接入网络(cloud radio access network，CRAN)场景下的无线控制器、集中单元(centralized unit，CU)，和/或分布单元(distributed unit，
DU)。所述接入网设备还可以是服务器等。例如，车到一切(vehicle to everything，V2X)技术中的网络设备可以为路侧单元(road side unit，RSU)。下面以接入网设备是基站为例，对接入网设备与所述终端设备之间的通信进行说明。基站可以与终端设备进行通信，也可以通过中继站与终端设备进行通信。终端设备可以与不同接入技术中的多个基站进行通信。所述核心网设备用于实现移动管理，数据处理，会话管理，策略和计费等功能。不同接入技术的系统中实现核心网功能的设备名称可以不同，本申请实施例并不对此进行限定。以5G系统为例，所述核心网设备包括：访问和移动管理功能(access and mobility management function，AMF)、会话管理功能(session management function，SMF)、网络开放功能(network exposure function，NEF)、应用功能(application function，AF)或用户面功能(user plane function，UPF)等。其中，AF还可以视为第三方应用服务器，简称为应用服务器。
本申请实施例中，“至少一个”是指一个或者多个，“多个”是指两个或两个以上。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B的情况，其中A,B可以是单数或者复数。在本申请的文字描述中，字符“/”，一般表示前后关联对象是一种“或”的关系。“包括A，B和C中的至少一项(个)”可以表示：包括A；包括B；包括C；包括A和B；包括A和C；包括B和C；包括A、B和C。
本申请实施例提及“第一”、“第二”等序数词是用于对多个对象进行区分，不用于限定多个对象的大小、内容、顺序、时序、优先级或者重要程度等。例如，第一信令和第二信令，并不是表示这两个信令的内容、信息量大小、发送顺序、发送端/接收端、优先级或者重要程度等的不同。
本申请实施例提供的技术方案可以应用于第三代通信系统the 3th generation，3G)，例如通用移动通信系统(universal mobile telecommunications system，UMTS)系统。或者还可应用于第四代(the 4th generation，4G)通信系统，例如长期演进(long term evolution，LTE)系统。或者可以应用于第五代(the 5th generation，5G)通信系统，例如新空口(new radio，NR)，或者还可以应用于可以未来的通信系统，例如第六代(the 6th generation，6G)系统等。或者还可应用于无线局域网(wireless local area network，WLAN)通信系统等。
请参照图1，为本申请实施例提供的一种应用场景示意图。图1包括中间设备110和终端设备120，中间设备110例如为接入网设备(例如基站，或者接入节点等)，该接入网设备可实现读写器的功能，或者也可以不实现读写器的功能；或者，中间设备110例如为 终端设备，该终端设备例如实现读写器的功能；或者，中间设备110例如为接入网设备下的小区；或者，本申请实施例中的中间设备110可被替代为小区。
其中，如果中间设备110是基站，则终端设备120与中间设备110之间可通过Uu接口通信；或者，如果中间设备110是接入节点，则终端设备120与中间设备110之间可通过侧行链路(sidelink，SL)通信。另外，如果中间设备110是终端设备，则中间设备110还可以与接入网设备连接，通过Uu接口通信，例如中间设备110通过该接入网设备与核心网通信。
请参照图2，为本申请实施例提供的另一种应用场景示意图。图2包括中间设备110、IAB节点200以及终端设备120。IAB节点200与终端设备120之间可以双向通信，如图2所示；或者，IAB节点200与终端设备120之间也可能只进行单向通信。
其中，如果IAB节点200与终端设备120之间可以进行双向通信，则IAB节点200可视为中间设备110与终端设备120之间的中继节点，终端设备120的上下行数据都可经过该IAB节点200转发。
或者，如果IAB节点200与终端设备120之间只能进行单向通信，例如IAB节点200可以向终端设备120发送信息，但终端设备120不能向IAB节点200发送信息，那么在传输下行数据时可将IAB节点200视为中间设备110与终端设备120之间的中继节点，来自中间设备110的下行数据可经IAB节点200转发后到达终端设备120；而在传输上行数据时，终端设备120可以不经过IAB节点200，而是直接将上行数据发送给中间设备110。其中，图2中的中间设备110的实现形式可参照图1论述的内容。
请参照图3，为本申请实施例提供的又一种应用场景示意图。图3包括中间设备110、接入网设备300以及终端设备120。需要说明的是，图3中是以中间设备110不是接入网设备为例，例如，图3中的中间设备110为终端设备或接入节点。例如，中间设备110可直接与终端设备120通信，或者，中间设备110也可以通过接入网设备300与终端设备120通信。中间设备110和/或接入网设备300能够与核心网连接。
需要说明的是，图1至图3所示的实施例是以中间设备110的数量为一个进行示例，实际上中间设备110的数量可以是多个，在中间设备110的数量为多个的情况，其中两个中间设备110的通信覆盖范围可能存在部分重叠，或者完全重叠，或者完全不重叠。在中间设备110有多个的情况下，可将多个中间设备110依次称为第一设备、第二设备等。
为了更好地介绍本申请实施例，下面结合附图介绍本申请实施例所提供的方法。在本申请的各个实施例对应的附图中，凡是可选的步骤均用虚线表示。本申请的各个实施例所提供的方法均可应用于图1至图3中的任一附图所示的场景。例如，本申请的各个实施例所涉及的第一设备和第二设备的实现方式可参照图1至图3中的任一附图所示的中间设备110，具体可参考上文介绍；本申请的各个实施例所涉及的终端设备，例如为图1至图3中的任一附图所示的终端设备120，并且在本申请的各个实施例中是以终端设备为UE进行介绍。另外本申请实施例还涉及第一核心网设备和第二核心网设备，在图1至图3中并未示意。例如第一核心网设备为接入及移动性管理功能(access and mobility management function，AMF)或会话管理功能(session management function，SMF)等，第二核心网设备为应用服务器、应用功能(application function，AF)、网络开放功能(network exposure fuction，NEF)或SMF等，在本申请的各个实施例中是以第一核心网设备是AMF，以及第二核心网设备是AF为例。其中，一个核心网设备与另一个核心网设备之间可相互通信， 一个核心网设备与接入网设备可相互通信，例如接入网设备与AMF可相互通信，AMF与AF可相互通信等。
本申请实施例提供一种寻呼方法，请参照图4，为该方法的流程图。
S401，AF向AMF发送信令1。相应的，AMF接收来自AF的信令1。该信令1用于寻呼UE。本申请实施例中的信令1又可称为第七信令。
示例性的，AF可直接向AMF发送信令1，例如，AF可通过AMF的服务化接口向AMF发送信令1，AMF的服务化接口例如为Namf接口；或者，AF也可通过其他核心网设备向AMF发送信令1，其他核心网设备例如为SMF。
该信令1例如为应用层寻呼(或盘存(inventory)，或盘点)信令，或者，信令1例如类似于蜂窝网络中的寻呼(paging)消息。信令1可用于寻呼UE；或者，信令1可用于选择UE；或者，信令1可用于指示(或，触发)UE接入；或者，信令1可用于指示(或，触发)UE发送上行数据；或者，信令1可用于指示(或，触发)UE与网络(例如接入网设备)建立连接；或者，信令1可用于指示接入UE；或者，信令1可用于指示(或，触发)UE发起随机接入等。本申请实施例以信令1用于寻呼UE为例，通过信令1所寻呼的UE可称为待寻呼的UE，也可称为待接入(或盘存，或盘点)的UE等。
其中，由于AF可能向AMF发起多轮用于寻呼UE的信令(例如，AF可能会多次向AMF发送用于寻呼UE的信令，其中的一次就视为一轮)，为了便于区分，本申请实施例中将通过信令1所发起的寻呼视为本轮寻呼，又可以称为第N轮寻呼。
作为一个示例，信令1可指示待寻呼的UE的第一标志位(flag)的信息，通过指示第一标志位的信息，可以达到寻呼UE的目的。或者，信令1可用于寻呼UE，以及，还可指示待寻呼的UE的第一标志位的信息。第一标志位的信息用于确定(或选择(select))，或寻呼)UE。例如，一个UE的标志位的信息满足信令1指示的第一标志位的信息，则该UE可被寻呼。
其中，标志位也可称为盘存标志位(inventoried flag)、盘点标志位、库存标志位或选择标志位等。标志位可理解为预存在UE内的值，例如，预存在UE的内存中。或者，标志位可理解为是一个信息的取值，例如，标志位为信息a的取值，信息a例如占用1比特(bit)，则标志位可包括“0”和“1”这两种取值。或者，标志位也可以理解是UE中的一个电容。
作为一个示例，一个UE可维护至少一个标志位，不同的UE维护的标志位可能完全相同，或部分相同，或完全不同。其中，第一标志位可以是多个UE都维护有的同一种的类型的标志位，因此信令1通过指示第一标志位的信息，便可寻呼这多个UE中的部分或全部UE。例如，多个UE包括UE1和UE2，UE1维护了标志位S0和标志位S1，UE2维护了标志位S0、标志位S1、标志位S2和标志位S3，可见标志位S0和标志位S1是UE1和UE2均有维护的标志位。信令1所指示的第一标志位可以是这些标志位中的任一个，例如第一标志位例如为标志位S1，则信令1可通过第一标志位(即标志位S1)的信息寻呼UE1和/或UE2。
第一标志位的信息可指示待寻呼的UE的第一标志位的类型(例如指示待寻呼的UE的第一标志位的类型为第一类型)，和/或，指示待寻呼的UE的第一标志位的状态(例如指示待寻呼的UE的第一标志位的状态为第一状态)。其中，第一类型可以是标志位的多种类型中的任意一个，第一状态可以是第一标志位的多种状态中的任意一种，本申请实施例 对此不做限定。下面对UE的标志位的类型和标志位的状态分别进行介绍。
1、标志位的类型。
该UE维护了至少一个标志位，其中一个标志位对应一种类型，不同的标志位的类型可以不同。或者，一个标志位也可以对应多种类型，在本申请实施例中主要以一个标志位对应一种类型进行示例。例如，一个UE包括4个会话(会话S0、会话S1、会话S2和会话S3)，每个会话可视为一个标志位，而每个会话也可视为一种类型。
其中，UE维护的一个标志位的类型，可根据该标志位的值和/或该UE的硬件结构确定。该标志位的类型可以表示为会话(session)、节、或标志位标识等。
作为一个示例，在UE的标志位仅包括一种类型，或者UE的标志位没有类型之分的情况下，信令1可不指示第一标志位的类型，例如不指示第一类型。
2、标志位的状态。
标志位的状态又可称为盘存状态、盘点状态或库存状态等。一个标志位的状态可根据该标志位的值确定。一个标志位可以有多种可选的状态，例如2种状态。例如，如果一个标志位的值为0，则该标志位的状态为A；或者，如果该标志位的值为1，则该标志位的状态为B。其中，第一标志位的第一状态可理解为是第一标志位对应的多种状态中的一种。
其中，UE维护的一个标志位的类型与该标志位的状态也可以相关。例如，一个类型1的标志位，可以对应多种可选的状态；一个类型2的标志位，也可以对应多种可选的状态。而一个类型1的标志位和一个类型2的标志位，所对应的多种状态可以是相同的。例如，一个标志位的类型为会话S0，该标志位的状态可以是A或B；又例如，一个标志位的类型为会话S1，该标志位的状态也可以是A或B。
作为一种实施方式，UE所维护的一个标志位在某种类型下可以有一个初始状态(初始状态也可称为默认状态、默认取值、复位状态、初始取值、或复位取值等)。初始状态例如为在该UE复位(例如该UE上电)时该UE维护的一个标志位所处的状态。或者，初始状态也可以是指当该UE掉电后该UE维护的一个标志位所保持的状态。其中，在UE掉电后，该标志位的状态可以在一段时长内维持不变，这段时长的单位可以是百毫秒级、秒级或分钟级，本申请实施例对此不做限定。其中，UE维护的一个标志位在某种类型下的状态可以从初始状态改变为非初始状态。在改变后，在一定条件下，该标志位的状态又可恢复至初始状态。非初始状态是指一个标志位的多种状态中除了初始状态之外的状态。
UE维护的一个标志位在某种类型下的状态可以从初始状态改变为非初始状态，或者从非初始状态变化为初始状态，均认为该UE的该标志位的状态发生了变化。作为一个示例，一个标志位在某种类型下对应的一个状态需在一定的状态变化条件才会切换至另一个状态。状态变化条件是指，一个标志位在某种类型下，从一种状态变化为另一种状态所需的条件。
例如，一种状态变化条件为UE维持某种类型下的该标志位的状态的时长，该时长又可称为维护时长。对于维护时长可理解为，UE在达到该维护时长之后，该类型下的该标志位的状态会切换为另一种状态。
作为一个示例，UE维护的一个标志位在某种类型下的一种状态变化为另一种状态的状态变化条件，与该标志位在该某种类型下的另一种状态变化为一种状态的状态变化条件不同。
例如，UE在第一条件下维护会话S1保持为状态A的时长，与该UE在第一条件下维 持该会话S1保持为状态B的时长不同。其中，第一条件是指UE当前的通电状态，例如，UE处于上电状态，或者UE处于掉电状态。
作为一个示例，对于UE维护的一个标志位的一种状态来说，在该标志位的类型不同时，则该种状态对应的状态变化条件可能相同，也可能不同。状态变化条件的含义和内容可参照前文。
示例性的，对于该标志位的一种状态，在该标志位的类型不同时，UE在第一条件下维持该种状态的时长不同。
例如，UE在掉电情况下，使得UE维护的会话S0对应的状态B的时长为0，该UE维护会话S1对应的状态B的时长的范围为[500毫秒(ms)，5秒(s)]，其中，UE在掉电情况下，该UE至少能够在500ms内使得该会话S1对保持状态为B，最多能够在5s内使得该标志位保持状态为B。
下面以标志位的类型为第一类型为例，对第一类型对应的状态变化进行示例介绍。请参照图5，为本申请实施例提供的第一类型的状态的变化过程的示意图。图5是以第一类型为会话S0、会话S1、会话S2或会话S3，以及以每个会话的状态(即标志位的状态)为A或B为例。
(1)在第一类型为会话S0的情况下，UE上电之后，例如会话S0的状态为A。在该UE被第一设备识别(或读取，或写入)一次或者UE接入第一设备完成之后，该UE将该会话S0的状态从A变成B。如果该UE一直有电，则该UE可以维持该会话S0的状态，例如，一直维持该会话S0的状态为B。如果该UE掉电(或称为断电)，则该UE不保存该会话S0的状态，这种情况下，会话S0的状态为空。一旦该UE再次上电，该UE可确定该会话S0的状态为A。
(2)在第一类型为会话S1的情况下，UE上电之后，会话S1的状态例如A或B。当UE被第一设备识别(或读取，或写入)一次之后，该UE确定会话S1的状态翻转(例如UE上电之后会话S1的状态为A，则此时会话S1的状态从A变更为B；又例如，UE上电之后会话S1的状态为B，则此时会话S1的状态从B变更为A)。在该UE掉电之后，该UE可维持会话S1的状态为B，其中，能够维持的时长的范围为[500ms，5s]。在该UE再次上电之后，该UE可确定会话S1的状态为B。后续，会话S1的状态可在一定时长内从B变为A，其中，该一定时长的取值是不固定的。
(3)会话S2的状态变化情况和会话S3的状态变化情况相同，下面以会话S2为例介绍。在第一类型为会话S2的情况下，UE上电之后，会话S2的状态为A或B。当该UE的会话S2被识别(或读取，或写入)过一次之后，该会话S2的状态翻转。如果该UE一直有电，则UE可一直维持该会话S2的状态。在该UE掉电之后，该UE可维持该会话S2的状态的时长大于或等于2s，例如，该会话S2的状态可维持10s。
作为一个示例，如果多个UE只维护同一种标志位的情况下，第一标志位即为该标志位，则第一标志位的信息可用于指示该标志位的状态(例如第一状态)。如果多个UE均分别维护多个标志位的情况下，该第一标志位可为多个UE共同维护的一个标志位，则第一标志位的信息可用于指示该第一标志位的类型(例如第一类型)，或者该第一标志位的信息可用于指示该第一标志位的类型(例如第一类型)以及该第一标志位的状态(例如，第一状态)。
可选的，AF可根据业务需求，确定待寻呼的UE的第一标志位的信息。或者，AF可 从其他核心网设备(如SMF)接收待寻呼的UE的第一标志位的信息。
可选的，信令1还用于指示次数信息。该次数信息用于指示第一设备寻呼UE的次数，可进一步理解为第一设备向UE发送用于指示接入第一设备的接入指令的次数。该次数可为一次或多次。其中，AF可根据业务需求等确定该次数信息；或者，AF可从其他核心网设备(如SMF)接收该次数信息。
可选的，信令1还用于指示标识信息。该标识信息用于指示待寻呼的UE的标识需满足该标识信息。该标识信息用于指示待寻呼的UE的标识，或者，用于指示待寻呼UE所对应的组标识。组标识用于指示多个UE，这多个UE中的部分或全部UE为待寻呼的UE。
可选的，信令1还用于指示掩码(mask)信息。掩码信息用于指示第一掩码。
可选的，该掩码信息还用于指示待寻呼的UE中的掩码在UE中的存储位置。该存储位置可指示待寻呼的UE的掩码在UE内的存储区域中的起始位置、终止位置或存储长度等信息中的至少一项。UE接收该掩码信息之后，可根据该掩码信息确定该UE对应的存储位置中的掩码(为便于区分，下文将该UE中的该存储位置中的掩码称为第二掩码)。第一掩码可用于与UE中的存储位置中的第二掩码进行匹配。例如，如果UE中的第二掩码与第一掩码匹配，则该UE确定将该UE的第一标志位的状态改变为第一状态，如果该UE中的第二掩码与第一掩码不匹配，则该UE确定将该UE的第一标志位的状态改变为第二状态。例如，该掩码信息被预配置(例如由协议配置)在AF中，AF可以从其他核心网设备获取的，或者AF可根据业务需求确定的，本申请实施例对此不做具体限定。
需要说明的是，本申请实施例中的第二掩码可以是应用层标识，或者也可以是非应用层标识，例如为UE存储的信息。
作为一个示例，该掩码信息可为上述的标识信息，即第一掩码为上述标识信息所指示的标识。这种情况下，该掩码信息可用于指示待寻呼的UE的标识需与该标识信息指示的该标识匹配。
可选的，信令1还用于指示动作信息。该动作信息用于指示改变待寻呼的UE的第一标志位的状态。
例如，动作信息可指示UE的第一标志位的状态改变(或调整，或翻转，或变更)为第一状态。
又例如，该动作信息可理解为用于指示改变符合第二条件的UE和/或不符合第二条件的UE的第一标志位的状态。其中，第二条件例如为掩码信息指示的第一掩码与UE中存储的第二掩码相同。第二条件可被预配置在UE中。其中，符合第二条件的UE和/或不符合第二条件的UE可以是待寻呼的UE中的部分或全部。
示例性的，动作信息可指示将符合第二条件的UE的第一标志位的状态改变为第一状态，和/或，将不符合第二条件的UE的第一标志位的状态改变为第二状态。其中，第一状态和第二状态可以不同。例如，第一状态为A，第二状态为B，如果一个UE中的第二掩码与掩码信息指示的第一掩码匹配，则该UE将标志位的状态改变为A；如果一个UE的掩码第二掩码与掩码信息指示的第一掩码不匹配，则该UE将标志位的状态改变为B。
或者，动作信息可指示将不符合第二条件的UE的第一标志位的状态改变为第一状态，和/或，将不符合第二条件的UE的第一标志位的状态改变为第二状态。
需要说明的是，如果UE的第一标志位的状态已为动作信息所指示的改变后的状态，则该UE接收动作信息之后可不必执行改变第一标志位的状态的动作。
又例如，第二条件例如为UE的标识符合上述标识信息指示的标识。该示例适用于掩码信息相当于前文中的标识信息的情况。在这种情况下，相当于第一设备选择了符合第二条件的UE接入。
作为一个示例，该动作信息还可指示改变其他标志位的状态，其他标志位是指除了UE维护的至少一个标志位中的第一标志位之外的标志位，本申请实施例对此不做限定。
S402，AMF向第一设备发送信令2。相应的，第一设备接收来自AMF的信令2。信令2用于寻呼UE。本申请实施例中信令2又可以称为第一信令。
当第一设备为接入网设备时，可直接从第一核心网设备(如AMF)接收信令2。当第一设备为不是接入网设备(如终端设备)时，第一设备可通过接入网设备接收来自第一核心网设备的信令2。
信令2的含义可参照前文信令1的内容，此处不再列举。
作为一个示例，信令2可通过指示待寻呼的UE的第一标志位的信息，达到寻呼UE的目的。或者，该信令2分别用于寻呼UE，以及还指示待寻呼的UE的第一标志位的信息。
其中，信令2可显式地指示待寻呼的UE的第一标志位的信息，例如信令2包括第一标志位的信息。或者，信令2可隐式地指示待寻呼的UE的第一标志位的信息。
待寻呼的UE的第一标志位的信息的内容可参照前文S401论述的内容。该待寻呼的UE的第一标志位的信息可以是AMF自行确定的，AMF确定该标志位的信息的方式可参照前文AF确定标志位的信息的内容。或者，该待寻呼的UE的第一标志位的信息可以是AMF根据信令1确定的。
作为一个示例，信令2可为非接入层(non-access stratum，NAS)信令，NAS信令又可以称为NAS消息。如此，第一设备接收信令2之后，无需感知信令2中的内容，有利于提升信令2包含的信息的安全性，且有利于减少第一设备的处理量。
可选的，信令2还可用于指示次数信息。该次数信息的含义可参照前文论述的内容。该次数信息所指示的次数可以是AMF确定的，或者AMF根据信令1确定的。
在次数信息指示的次数为多次的情况下，相当于信令2指示了第一设备向UE发起多次寻呼，在第一设备接收信令2之后，第一设备可根据信令2，发起触发多次寻呼。换言之，一轮寻呼(如本轮寻呼)下，第一设备可触发多次接入。对于UE而言，如果一个UE在第一次寻呼过程中没有成功接入第一设备，则可以再下一次寻呼中继续尝试接入，而第一次寻呼中成功接入第一设备的终端设备，在下一次待寻呼中可以不用再次接入第一设备。在一轮寻呼下，对于待寻呼的UE接入第一设备可成功一次，但在一轮寻呼下，UE有可能通过第一设备触发的多轮接入后才成功接入第一设备。
其中，一轮寻呼可理解为，在信令1的指示下，第一设备对UE进行的至少一次寻呼；或者可理解为，第一设备在一个寻呼周期内进行的寻呼，该寻呼周期可以是AF通过信令1指示的。其中，该寻呼周期的时长取值可以为AF发送两次寻呼UE的信令之间的时间间隔。
在次数信息指示的次数为一次的情况下，或者在信令2未指示次数信息的情况下，第一设备接收信令2之后，第一设备可根据信令2，发起一次寻呼(或接入，或盘点，或盘存)。
可选的，信令2还用于指示待寻呼的UE的标识信息。其中，标识信息的含义可参照前文。
可选的，信令2还用于指示掩码信息。掩码信息的含义可参照前文S401论述的内容。掩码信息可以是AMF确定的，或者AMF根据信令1确定的。
作为一个示例，该掩码信息可为上述的标识信息。其中，标识信息的含义可参照前文。
可选的，信令2还用于指示动作信息。动作信息的含义可参照前文。AMF获得动作信息的方式可参照AMF获得掩码信息的内容，此处不再列举。
在另一种可能的实施方式中，第一核心网设备可以是SMF，这种情况下，上述S401和S402中的AMF可替换为SMF。
作为一个示例，第一设备可直接寻呼UE，而无需核心网设备(如AMF或AF等)触发，这种情况下，无需执行S401至S402的步骤，即S401至S402的步骤是可选的步骤。
S403，第一设备发送信令3。相应的，一个或多个UE接收来自第一设备的信令3。该信令3用于指示待寻呼的UE的第一标志位的信息。第一标志位的信息的含义可参照前文S401论述的内容。本申请实施例中的信令3又可以称为第二信令。在图4所示的实施例中以第一UE接收该信令3为例。
其中，寻呼可以理解为触发终端设备接入第一设备，或者触发终端设备与第一设备建立连接，或者触发终端设备与第一设备进行数据交互。
该信令3例如为第一设备所发送的寻呼(paging)信令，该信令3例如类似于蜂窝网络中的寻呼。该信令3用于寻呼一个或多个UE；或者，信令3用于选择一个或多个UE；或者，信令3用于指示(或，触发)一个或多个UE发送上行数据；或者，信令3用于指示(或，触发)一个或多个UE与网络(例如接入网设备)建立连接；或者，信令3用于指示一个或多个UE接入；或者，信令3用于指示(或，触发)一个或多个UE发起随机接入等。本申请实施例以该信令3用于寻呼一个或多个UE为例，这一个或多个UE可认为是待寻呼的UE。
需要说明的是，本申请实施例涉及的待寻呼的UE可理解为处于UE处于非连接态，即UE与第一设备之间没有通信连接，或者可理解为待寻呼的UE的标志位的状态为复位状态或初始状态。本申请实施例涉及的被寻呼的UE可以理解为进入与第一设备通信的状态。
需要说明的是，在信令2指示的一轮寻呼中，第一设备可能发起一次或多次寻呼。在信令2指示第一设备发起多次寻呼的情况下，为了便于区分，本申请实施例中将信令3发起的这次寻呼视为本次寻呼(又可以称为第M次寻呼)，换言之，下文中提到的本次寻呼均可理解为通过信令3发起的寻呼。这种情况下，信令3所指示的第一标志位的信息，可作为本轮寻呼中的一次寻呼(或选择，或确定)的UE的标志位需要满足的信息，或者可作为本轮寻呼中的每一次寻呼的UE的标志位需要满足的信息。
作为一个示例，如果信令2为NAS信令，那么第一设备无需感知待寻呼的UE的标志位的信息，直接发送该NAS信令。这种情况下，信令2和信令3均为该NAS信令。
作为另一个示例，第一设备确定待寻呼的UE的第一标志位的信息，并生成信令3。
方式一，第一设备根据信令2，确定第一类型和/或第一状态。
在信令2指示了待寻呼的UE的第一标志位的信息的情况下，第一设备可将信令2指示的待寻呼的UE的第一标志位的类型作为第一类型，和/或，第一设备可将信令2中指示的待寻呼的UE的第一标志位的状态作为第一状态。
方式一中由于无需第一设备确定第一标志位的信息，有利于减少第一设备的处理量。
方式二，第一设备可自行确定第一类型和/或第一状态。
下面对第一设备确定第一类型和/或第一状态的方式进行示例介绍。
确定第一类型的一种方式(称为子方式A1)，第一设备可从标志位的多种类型中，随机确定一种类型作为第一类型。其中，标志位的多种类型可被预配置在第一设备中，例如，由协议配置在第一设备中。
确定第一类型的一种方式(称为子方式A2)，第一类型可为协议规定的默认值。
确定第一类型的一种方式(称为子方式A3)，第一设备可根据第一设备上一轮寻呼(或第N-1轮寻呼)过程的碰撞情况，确定第一类型。碰撞可理解为两个或两个以上的UE在同一个时间单元向第一设备发送上行数据。
第一种情况，如果第一设备在执行本轮寻呼之前，还可能发起了一轮寻呼(又可称为第(N-1)轮，或又可以称为上一轮寻呼)。在本申请实施例中，第一设备可根据上一轮寻呼过程中第一设备检测到碰撞的次数和空闲的接入机会数目，确定还未接入第一设备的UE的数目，或者根据在上一轮寻呼过程中已成功接入第一设备的UE的数量(称为第二数量)，确定待寻呼的UE的标志位的类型。下面以根据第二数量，确定待寻呼的UE的标志位的类型为例进行介绍。
示例性的，如果第二数量大于或等于第二阈值，表示上一轮寻呼过程中成功接入第一设备的UE的数量较多。假如选择的标志位对应的状态维持时长较短，则更容易引起UE之间的碰撞，因此在本申请实施例中，第一设备将待寻呼的UE的标志位的类型确定为与上一轮寻呼不同的类型。例如，上一轮寻呼的UE的第二标志位的类型为第二类型，则第一设备确定待寻呼的UE的第一标志位的类型为第一类型。其中，第一类型的第一标志位的状态的维持的时长比第二类型的第二标志位的状态的维持的时长更长。如果第二数量小于第二阈值，表示之前寻呼的UE的数量相对合适，则第一设备确定待寻呼的UE的第一标志位的类型与上一轮寻呼的类型相同，或者可理解为第一设备在本轮寻呼过程中的这次寻呼中不改变上一轮待寻呼的UE的标志位的类型。
确定第一状态的一种方式(称为子方式B1)，第一设备可从多种标志位的状态中，随机确定一种状态作为第一状态。多种标志位的状态可预被配置在第一设备中，例如由协议配置在第一设备中。
确定第一状态的一种方式(称为子方式B2)，第一设备将第一标志位的初始状态确定为第一状态。初始状态的含义可参照前文。
确定第一状态的一种方式(称为子方式B3)，第一设备可根据第二数量，确定待寻呼的UE的第一标志位的状态。第二数量的含义可参照前文。
示例性的，如果第二数量大于或等于第二阈值，第一设备确定待寻呼的UE的第一标志位的状态调整为与上一轮寻呼过程中不同的状态。如果第二数量小于第二阈值，则第一设备确定待寻呼的UE的第一标志位的状态与上一轮寻呼的状态相同。
确定第一状态的一种方式(称为子方式B4)，第一状态可被预配置在第一设备中，例如，由协议预配置在第一设备中。
需要说明的是，第一设备可采用上述子方式A1和子方式A3中的任意一种子方式确定第一类型，可采用子方式B1至子方式B4中的任意一种子方式确定第一状态。
方式二可适用于信令2没有指示待寻呼的UE的第一标志位的信息的情况。在方式二中，可由第一设备自行灵活地确定第一标志位的信息。另外，第一设备还可基于上一轮寻 呼所采用的标志位的信息，灵活调整待寻呼UE的第一标志位的信息。
方式三，第一设备可结合上述方式一和方式二，确定待寻呼的UE的第一标志位的信息。
示例性的，信令2指示了第一类型，第一设备根据信令2确定了第一类型，第一设备自行确定第一状态。又或者，信令2指示了第一状态，第一设备根据信令2确定了第一状态，第一设备自行确定第一类型。
可选的，信令3指示的第一状态可理解为用于指示设置UE的第一标志位的状态，以及还可用于指示选择设置后的状态满足第一状态的UE接入第一设备。设置UE的标志位的状态例如为将符合第二条件的UE的标志位的状态置为第一状态，不符合第二条件的UE的第一标志位的状态置为第二状态。
可选的，信令3还用于指示掩码信息。掩码信息的含义可参照前文论述的内容。掩码信息可以是第一设备确定的，或者根据信令2确定的。
可选的，信令3还用于指示动作信息。动作信息的含义可参照S401论述的内容。第一设备获得动作信息的方式可参照第一设备确定掩码信息的内容。
例如，信令3为选择(selcet)信令。信令3中的第一字段用于指示第一类型和/或第一状态。第一字段例如为选择信令中的目标(target)字段。例如，target字段的取值为000，则第一类型为会话S0。又例如，信令3为选择信令和查询(query)信令，第一字段例如为查询信令中的会话(session)字段和目标(target)字段，会话字段用于指示第一类型，目标字段用于指示第一状态。例如，会话字段的取值为00，表示第一类型为会话S0，目标字段为0，表示会话S0的状态为A。
在一种可能的实施方式中，在一次寻呼下，第一设备可通过一个信令寻呼UE，例如，第一设备可以通过信令3寻呼UE。或者，一次寻呼下，第一设备可通过两个信令寻呼UE。当通过两个信令寻呼UE时，这两个信令可依次分为第一级寻呼信令和第二级寻呼信令。第二级寻呼信令指示的信息与第一级寻呼信令指示的信息可以相同或者不同。第二级寻呼信令可与第一级寻呼信令相关，例如，第二级寻呼信令对第一级寻呼信令指示的内容进行了补充指示，例如，第一级寻呼信令指示了第一标志位的类型，第二级寻呼信令指示了第一标志位的状态。又例如，第一级寻呼指令指示了动作信息，第二级寻呼指令指示了第一标志位的第一状态，相当于第一级寻呼指令为第二级寻呼指令选择的状态进行选择指示。例如，第二级寻呼信令对第一级寻呼信令指示的内容进行了调整，例如，第一级寻呼信令指示了第一标志位的第二状态，第二级寻呼信令指示了第一标志位的第一状态。
在一种可能的实施方式中，在信令2指示一轮寻呼下的多次寻呼中，第一设备灵活地根据一个或两个信令完成一次寻呼。例如，第一设备可在第一次寻呼中通过两个信令寻呼UE，第一设备在第二次寻呼中通过一个信令寻呼UE。由于第一设备不必在每次寻呼中均通过两个信令寻呼UE，有利于减少第一设备的信令开销。
作为一个示例，第一UE在接收信令3之后，可直接确定是否接入第一设备。这种情况下，第一设备相当于仅通过信令3寻呼UE，也就相当于信令3单独触发了本轮寻呼中的一次寻呼。这种情况下，该信令3触发的这一次寻呼可视为本次寻呼，或视为第M次寻呼。在UE为标签，第一设备为读写器的情况下，一个信令3相当于实现了选择信令和查询信令这两个信令的功能，有利于节省第一设备的信令开销。
其中，信令3指示的内容不同，第一UE根据信令3指示的内容，确定是否需要接入 第一设备的具体内容也存在区别，下面分别介绍。
示例1，信令3指示第一类型。
如果第一UE的类型为第一类型，则确定本次接入第一设备。如果第一UE的类型不为第一类型，则确定本次不接入第一设备。
示例1适用于一个UE的标志位有且仅有一种类型，且存在两个UE的类型不同的情况。这种情况下，第一设备可仅根据第一类型，确定待寻呼的UE。
示例2，信令3指示第一状态。
如果第一UE的类型为第一状态，则确定本次接入第一设备。如果第一UE的类型不为第一状态，则确定本次不接入第一设备。
示例2可适用于每个UE的标志位没有类型之分，或者任意两个UE的标志位的类型均为同一个的情况。
示例3，信令3指示动作信息和第一状态。
第一UE根据第二UE是否符合第二条件，对第一UE的状态进行相应的改变。例如，如果第一UE符合第二条件，则将第一UE的状态调整为A。如果第一UE不符合第二条件，则将第一UE的状态标签调整为B。
如果第一UE调整后的状态为第一状态，则确定本次接入第一设备。如果第一UE调整后的状态不为第一状态，则确定本次不接入第一设备。
示例3可适用于每个UE的标志位没有类型之分，或者任意两个UE的标志位的类型均为同一个的情况。
示例4，信令3指示第一类型和第一状态。
第一UE确定该第一UE的标志位的类型包括第一类型，且该第一类型对应的标志位的状态为第一状态，则确定本次接入第一设备。如果第一UE的类型不包括第一类型，和/或该第一UE的第一类型的标志位的状态不为第一状态，则确定本次不接入第一设备。
示例5，信令3指示第一类型和动作信息。
第一UE根据是否符合第二条件，改变第一类型对应的状态。
如果第一UE符合第二条件，则确定本次接入第一设备。如果第一UE的类型不包括第一类型，和/或第一UE不符合第二条件，则确定本次不接入第一设备。
示例6，信令3指示第一类型、第一状态和动作信息。
第一UE根据是否符合第二条件，调整第一类型对应的状态。如果第一UE的调整后的第一类型对应的状态为第一状态，则确定本次接入第一设备。如果第一UE确定该第一UE的调整后的第一类型对应的状态不为第一状态，则确定本次不接入第一设备。这种情况下，第一状态表示的是UE符合第二条件，且该UE的标志位的状态在执行对应动作信息后的标志位的状态。
在示例1至示例6中，信令3相当于直接指示了待寻呼的UE所需满足的标志位的信息。在次数信息指示的次数为一次的情况下，那么信令3相当于指示了一次寻呼，也相当于指示了一次接入。在次数信息指示的次数为多次的情况下，那么信令3相当于指示了一轮寻呼下的一次寻呼。
作为另一个示例，还可执行S404，即第一设备向第一UE发送信令4。相应的，第一UE接收来自第一设备的信令4。本申请实施例中的信令4又可以称为第四信令。需要说明的是，S404和S403的执行顺序可以是任意的，例如，先执行S403，后执行S404；或者， 先执行S404，再执行S403。
示例性的，信令3只指示上述示例中的第一类型、第一状态和动作信息中的一种或两种，信令4指示第一类型、第一状态和动作信息中除了信令3指示了之外的信息。
信令4用于指示第一状态，即相当于指示目前第一标志位的状态为第一状态的UE本次接入第一设备。这种情况下，第一UE可根据信令3和信令4确定本次是否接入第一设备。这种情况下，第一设备相当于通过信令3和信令4两个信令寻呼UE，也就相当于信令3和信令4一起触发了本轮寻呼中的一次寻呼。在这种情况下，信令3可视为第一级寻呼信令，信令4可视为第二级寻呼信令。例如，UE为标签，第一设备为读写器，则信令3可为选择信令，信令4可为查询信令。在这种情况下，信令3和信令4一起指示的这一次寻呼视为本次寻呼(又称为第M次寻呼)。
其中，信令3和信令4指示的内容不同，则第一UE确定本次是否接入第一设备的内容也存在区别，下面分别介绍。
示例7，信令3指示动作信息，信令4指示第一状态。
其中，信令4指示的第一状态可理解为确定待接入第一设备的UE的标志位的状态。第一UE确定本次是否接入第一设备的方式可参照前文示例3论述的内容。
示例8，信令4指示第一状态，信令4指示动作信息。
第一UE确定本次是否接入第一设备的方式可参照前文示例3论述的内容。
示例9，信令3指示第一类型，信令4指示动作信息。
第一UE确定本次是否接入第一设备的内容可参照前文示例5论述的内容。
示例10，信令3指示第一类型，信令4指示第一状态。
第一UE确定本次是否接入第一设备的方式可参照前文示例4的内容。
示例11，信令3指示第一类型和动作信息，信令4指示第一状态。
第一UE确定本次是否接入第一设备的方式可参照前文示例6的内容。
在示例7至示例11中，信令3和信令4一起指示了本次接入的UE，完成了一次寻呼。
作为一个示例，在信令3指示了掩码信息的情况下，第一UE可确定满足第一UE第二条件之后，再根据第一标志位的信息，确定是否接入第一设备。
作为一个示例，在第一设备无需改变UE的标志位的状态的情况下，第一设备无需指示动作信息，即这种情况下，信令3和信令4均无需指示动作信息。
S405，第一设备向第一UE发送信令5。相应的，第一UE接收来自第一设备的信令5。本申请实施例中的信令5又可以称为第五信令。
信令5可用于指示确认第一UE接入第一设备。例如，信令5通过指示第一UE的最大时间单元范围，以确认第一UE接入第一设备。最大时间单元范围可理解为时间单元的一个最大范围，第一UE可在该最大时间单元范围内选择时间单元。时间单元可理解为一种时域资源。
示例性的，时间单元例如为无线帧(radio frame)、子帧(subframe)、时隙(slot)、迷你时隙(mini-slot)、或正交频分复用(orthogonal frequency division multiplexing，OFDM)等。或者，本申请实施例中的时间单元，也可以不是固定时间长度的时间间隔，而是时域上的发送机会(或者称为接入机会)，不同的发送机会的时长可以相同或不同。
作为一个示例，信令5可以为前文的信令3或信令4。当信令5相当于前文信令3的情况下，即相当于信令3还指示了最大时间单元范围。当信令5相当于前文信令4的情况 下，相当于信令4还指示了最大时间单元范围。
作为一个示例，信令3或信令4可指示第一UE的最大时间单元范围，这种情况下，无需执行S405，即S405为可选的步骤。
可选的，信令3还用于指示待寻呼的UE的标识信息。该标识信息的含义可参照前文。
或者，掩码信息相当于信令3指示的标识信息。这种情况下，第一设备选择符合该标识信息的UE接入。
S406，第一UE向第一设备发送第一请求。相应的，第一设备接收来自第一UE的第一请求。
在第一UE确定接入第一设备的情况下，第一UE可向第一设备发送第一请求。第一请求用于请求接入第一设备。本申请实施例中的第一请求例如为随机接入过程中的第三消息(Msg3)。例如，第一请求也可以为一个随机数，或者为随机接入请求消息。
需要说明的是，S405-S406是UE可能执行的一种情况。例如，如果第一UE确定不接入第一设备，那么第一UE不执行S405-S406的步骤，即S405-S406是可选的步骤。
作为一个示例，第一UE可向第一设备发送上行数据。
作为一个示例，在第一UE成功接入第一设备之后，第一UE可改变第一标志位的第一状态。如此，可避免第一UE在一轮寻呼(或盘存，或盘点，或接入)中被第一设备识别(或读取，或写入)多次。
其中，第一设备通过一个UE的一个标志位的信息寻呼该UE，在第一设备成功接收了来自该UE的上行数据，就视为第一设备对该UE进行了一次识别。例如，第一设备为读写器，该UE为标签，读写器如果从该标签成功接收了该标签的电子产品码(electronic product code，EPC)，则视为读写器对该标签进行了一次识别。
作为一个示例，在信令2指示对UE进行多次寻呼的情况下，第一设备确定第一UE接入之后，还可发送再次发起用于寻呼UE的信令，以进行下一次寻呼(或称为第M+1次寻呼)。下一次寻呼过程可参照本次寻呼过程，此处不再列举。在这种情况下，第一设备再次发起用于寻呼UE的信令可以是一个第二级寻呼信令，这样第一设备无需再次发送第一级寻呼信令(即第二信令)，有利于减少第一设备的信令开销。
作为另一个示例，AMF在第一时刻(又可称为T1时刻)向第一设备发送信令2之后，可在第二时刻(又可以称为T2时刻)向第二设备发送信令6。本申请实施例中的信令6又可以称为第六信令。所述信令2和信令6内容可以相同。其中，AMF可向第二设备发送信令6的方式可参照AMF向第一设备发送信令2的内容。这种示例可适用于信令2指示了第一标志位的信息和/或动作信息的情况。其中，第一设备和第二设备为同一种类型的设备，例如，第一设备和第二设备为接入网设备的情况下，第一设备和第二设备可为两个相邻的接入网设备；又例如，第一设备和第二设备均为终端设备或接入节点的情况下，服务于第一设备的接入网设备与服务于第二设备的接入网设备可以相同或者相邻；又例如，第一设备和第二设备均为同一个接入网设备下的两个相邻的小区；又例如，第一设备可以被第一小区替代，第二设备可被第二小区替代。
例如，信令6可以指示待寻呼的UE的第二标志位的信息。第二标志位的信息可以是根据信令2指示的第一标志位的信息确定的。例如，第二标志位的信息用于指示第二标志位的类型为第二类型和/或状态为第二状态。例如，第二标志位的信息用于指示第二类型的UE接入第二设备；又例如，第二标志位的信息用于指示第二状态的UE接入第二设备；又 例如，第二标志位的信息用于指示第二类型和第二状态的UE接入第二设备。
示例性的，第二标志位与前文的第一标志位可以相同，或不同。第二类型也可与第一标志位的第一类型相同或不同。第二状态与第一标志位的第一状态也可相同或不同，例如，第二状态可以为第二标志位的初始状态。
示例性的，信令6指示的第二标志位的状态可以为第一状态。由于已成功接入第一设备的UE的第一标志位的状态可翻转为第二状态，因此在这种情况下，第二设备下选择接入第一标志位为第一状态的UE，可以减少第一设备和第二设备重复识别，通信重叠范围内的UE的情况。其中，通信重叠范围是指第一设备和第二设备的通信覆盖范围的重叠区域。并且，由于在T2时刻，AMF向第二设备指示信令6，这样可以避免已成功接入第一设备的UE的第一标志位的状态恢复至第一状态，造成该UE被第二设备重复识别的情况。
作为一种示例，第三时刻(即T3时刻)与第二时刻(即T2时刻)之间的时间差的绝对值小于第一类型对应的标志位的状态翻转后的状态的维持的时长，和/或，第三时刻(即T3时刻)与第二时刻(即T2时刻)之间的时间差的绝对值小于第一状态翻转后的状态的维持的时长。这种情况下，当AMF指示第二设备寻呼UE时，可以不需要指示动作信息，可以直接指示待寻呼的UE的标志位的类型和/或状态，这种情况下，第二标志位的类型可以为第一类型和/或状态为第一状态，即第二标志位的信息与第一标志位的信息相同，这使得满足这些标志位的类型和/或状态的UE接入第二设备。其中，第一状态翻转后的状态可能为第二状态。
其中，第三时刻(即T3时刻)为AMF确定第一设备完成本轮寻呼的时刻。
例如，AMF将接收来自的第一设备或接入网设备的第一指示信息的时刻确定为第三时刻。第一指示信息用于指示第一设备完成本轮寻呼。
示例性的，第一设备完成本轮寻呼之后，第一设备可以向AMF发送第一指示信息，AMF将接收到该第一指示信息的时刻确定为第三时刻。
又例如，AMF在指示第一设备进行本轮寻呼时，通过信令2指示了完成本轮寻呼的结束时刻，这种情况下，AMF可直接将本轮寻呼的结束时刻作为第三时刻。
可选的，第一时刻(即T1时刻)与第二时刻(即T2时刻)之间的时间差的绝对值小于第一类型对应的标志位的状态翻转后的状态的维持的时长，和/或，第一时刻(即T1时刻)与第二时刻(即T2时刻)之间的时间差的绝对值小于第一状态翻转后的状态的维持的时长。
在图4所示的实施例中，第一设备可指示待寻呼的UE的第一标志位的信息，而不必具体确定待寻呼的UE具体是哪些，第一设备可根据UE的标志位的信息寻呼UE，提供了一种寻呼UE的机制。由于无需具体确定待寻呼的UE，也可实现寻呼UE的过程，有利于简化第一设备寻呼UE的方式。并且，由于第一设备指示待寻呼UE的第一标志位的信息，便可寻呼一个或多个UE，而无需具体分别指示寻呼哪些UE，可减少第一设备发送的寻呼信令(即信令3)中的数据量，有利于减少寻呼开销。另外，信令2还可指示次数信息，使得第一设备可根据一个信令2，发起多次寻呼，有利于减少第一设备与第一核心网设备之间的交互次数。另外，第一设备在一次寻呼中，不必均通过两个信令寻呼UE，有利于提高第一设备寻呼的灵活性，以及减少第一设备的信令开销。另外，第一核心网设备还可根据指示的第一设备的第一标志位的信息，确定指示第二设备的第二标志位的信息，这样可降低第一设备和第二设备对相同的UE进行重复识别的情况。
请参照图6，为本申请实施例提供的一种寻呼方法的流程示意图。图6是以图4所示的实施例涉及的信令2指示第一类型和第一状态为例，以图4所示的实施例涉及的第一设备根据信令2确定第一类型和第一状态(即采用上述方式一确定第一类型和第一状态)为例，以及以图4所示的实施例涉及的信令3包括第一类型、第一状态和动作信息为例进行介绍。
S601，AF向AMF发送信令1。相应的，AMF接收来自AF的信令1。信令1用于寻呼UE。信令1的含义可参照前文论述的内容。
在另一种可能的实施方式中，也可以是SMF向AMF发送信令1。
作为一个示例，AMF可直接寻呼UE，而无需其他核心网设备(如AF)触发，这种情况下，无需执行S601，即S601是可选的步骤。
S602，AMF向第一设备发送信令2。相应的，第一设备接收来自AMF的信令2。信令2的含义可参照前文论述的内容。
AMF向第一设备发送信令2的方式可参照前文，此处不再列举。
在图6所示的实施例中，以第一设备根据信令2，确定第一类型和/或第一状态为例。换言之，以信令2隐式地指示了第一类型和第一状态为例。
示例性的，信令2包括如下信息(1)至(5)中的至少一种。
(1)频率信息，其用于指示第一设备寻呼的频率，可进一步理解为，频率信息指示第一设备在本轮寻呼中执行寻呼的频率，可理解为第一设备在信令2的指示发起的寻呼的频率。例如，频率信息指示第一设备每分钟(min)发起2次寻呼。
(2)次数信息，次数信息的含义可参照前文。例如，次数信息指示第一设备向UE发起5次寻呼。
(3)准确率信息，其用于指示接入第一设备的准确率，准确率又可以称为成功率。准确率可采用成功寻呼第一设备的UE的数量与第一设备执行寻呼的UE的数量之间的比值进行表示。第一设备执行寻呼的UE的数量可理解为第一设备发起寻呼的UE的数量。
(4)数量信息，其用于指示预期寻呼第一设备的UE的数量级。数量级可理解为预期寻呼第一设备的UE的数量的尺度或大小级别，例如，千级别或百级别等。
(5)寻呼时间信息，其用于指示第一设备执行寻呼的开始时间和/或结束时间。
信令2指示第一设备进行多次寻呼的情况下，执行寻呼的开始时间可理解为第一设备在信令2的指示下，执行第一次寻呼的开始时间，例如以第一设备接收到信令2作为执行寻呼的开始时间。执行寻呼的结束时间可理解为第一设备在信令2的指示下，最后一次执行寻呼的时刻。例如，以第一设备在信令2的指示下，最后一次向UE发送寻呼信令(如信令3或信令4)的时刻。信令3和信令4的含义可参照前文。
或者，信令2仅指示第一设备执行一次寻呼的情况下，执行寻呼的开始时间可理解为第一设备在信令2的指示下，开始本次寻呼的时间。
作为一个示例，信令2可通过指示上述信息(1)至(5)中的至少一种，以实现寻呼UE。或者信令2可单独用于寻呼UE，还指示上述信息(1)至(5)中的至少一种，本申请实施例对此不做限定。
需要说明的是，上述信息(1)至(5)可以是AMF根据业务需求确定的，或者AMF从其他核心网设备(如AF)获取的，本申请实施例对此不做限定。
作为一个示例，信令2也可包括掩码信息。掩码信息的含义可参照前文论述的内容。 AMF可根据业务需求确定掩码信息，或者根据信令2获得该掩码信息。
在另一种可能的实施方式中，第一核心网设备可以是SMF，这种情况下，上述S601和S602中的AMF可替换为SMF。
S603，第一设备发送信令3。相应的，一个或多个UE接收来自第一设备的信令3。
在本申请实施例中，是以第一UE接收该信令3为例、以及以信令3包括第一类型、第一状态为例。
在本申请实施例中，以第一设备根据信令3指示的信息(即第一设备采用上述方式一)，确定待寻呼的UE的标志位的类型为第一类型和/或状态为第一状态为例进行介绍。
示例性的，第一设备根据信令3，确定待寻呼的UE的标志位的状态的状态变化条件的需求(例如，状态需维持的时长需求)。由于同一种状态，对应不同类型的标志位时，在第一条件下的维持的时长不同，和/或，多个状态中存在至少两个状态在第一条件下的维持的时长不同，因此第一设备可确定与时长的需求匹配的状态所对应的标志位的类型确定为第一类型，和/或，第一设备将与时长的需求匹配的标志位的状态确定为第一状态。
下面对信令2指示的信息不同，第一设备确定第一类型和/或第一状态的方式进行介绍。
1、信令2用于指示上述信息(1)，即频率信息。
频率信息指示的频率越大，表示第一设备执行两次寻呼之间的时间间隔越短，这种情况下，第一设备可确定维持的时长较短的状态为第一状态，和/或确定维持的时长较短的状态对应的类型为第一类型。频率信息指示的频率越小，表示第一设备执行两次寻呼之间的时间间隔越长，这种情况下，第一设备确定维持的时长较长的状态为第一状态，和/或确定维持的时长较长的状态对应的类型为第一类型。
2、信令2用于指示上述信息(2)，即次数信息。
该次数信息所指示的次数越大，表示第一设备在一段时间内会相对频繁地进行寻呼，这种情况下，第一设备确定维持的时长相对较短的状态为第一状态，和/或确定维持的时长相对较短的状态所对应的类型为第一类型。该次数信息所指示的次数越小，表示第一设备会不会频繁地进行寻呼，这种情况下，第一设备确定维持的时长相对较长的状态为第一状态，和/或确定维持的时长相对较长的状态所对应的类型为第一类型。
3、信令2用于指示上述信息(3)，即准确率信息。
该准确率信息所指示的准确率越大，表示需要提高UE成功接入第一设备的可能性，而第一设备执行寻呼的次数越多，越能提高UE成功接入第一设备的可能性。在这种情况下，第一设备确定维持的时长较短的状态为第一状态，和/或确定维持的时长较短的状态对应的类型为第一类型。该准确率信息所指示的准确率越小，表示UE成功接入第一设备的可能性无需太大，因此第一设备执行寻呼的次数可相对较少。在这种情况下，第一设备确定维持的时长的状态为第一状态，和/或确定维持的时长较长的状态对应的类型为第一类型。
4、信令2用于指示上述信息(4)，即数量信息。
该数量信息指示的数量级越大，表示第一设备需寻呼的UE的数量越多，也就表示第一设备执行一次寻呼的处理量较大，而假如UE频繁地切换标志位的状态，无疑会导致第一设备的处理量过大。因此，在这种情况下，第一设备可确定维持的时长较长的状态为第一状态，和/或确定维持的时长较长的状态对应的类型为第一类型。该数量信息指示的数量级越小，表示第一设备需接入的UE的数量越小，第一设备执行一次寻呼的处理量相对更小。因此，在这种情况下，第一设备可确定维持的时长较长的状态为第一状态，和/或确定 维持的时长较长的状态对应的类型为第一类型。
5、信令2用于指示上述信息(5)，即接入时间信息。
如果寻呼时间信息指示了开始时间，第一设备可根据在开始时间之后已执行的寻呼次数，以及当前时间，确定每一次寻呼的时长。或者，如果寻呼时间信息指示了结束时间，第一设备可根据在开始时间之后已执行的寻呼次数，以及当前时间，确定每一次寻呼的时长。或者，如果寻呼时间信息指示了开始时间和结束时间，第一设备可确定每一次寻呼的时长。
如果每一次寻呼的时长相对短，那么第一设备可确定维持的时长较短的状态为第一状态，和/或确定维持的时长较短的状态对应的类型为第一类型。如果每一次寻呼的时长相对长，那么第一设备可确定维持的时长较长的状态为第一状态，和/或确定维持的时长较长的状态对应的类型为第一类型。
在一种可能的实施方式中，信令2如果指示了上述信息(1)至(5)中的两项或两项以上的信息，第一设备可结合两项或两项以上的信息，确定待寻呼的UE的标志位的类型对应的状态或标志位的状态的状态变化条件的需求，进而确定与状态变化条件的需求所对应的类型为标志位的第一类型和/或与该状态变化条件的需求匹配的状态为标志位的状态。
示例性的，第一状态可以为初始状态。初始状态的含义可参照前文。
可选的，信令3还可指示掩码信息。掩码信息的含义和第一设备获得掩码信息的方式可参照前文。
作为一个示例，信令3还可指示动作信息。动作信息的含义和第一设备获得动作信息的方式可参照前文。在图6所示的实施例中是以信令3还指示动作信息为例。该动作信息可以是第一设备根据信令2确定的，或者第一设备自行确定的，本申请实施例对此不做限定。
可选的，信令3还用于指示掩码信息。
作为一个示例，在信令3指示了掩码信息的情况下，第一UE确定满足第一UE第二条件之后，再根据第一标志位的信息，确定是否接入第一设备。
S604，第一UE改变第一UE的第一标志位的状态。
本申请实施例中以信令3的第二字段用于指示动作信息为例。其中，第二字段的不同取值下对应的状态变化内容可如表1所示。需要说明的是，表1是对第二字段、状态变化以及状态等进行示例介绍。
表1

如上述表1所示，在信令3中的第二字段的取值为000的情况下，如果第一UE符合第二条件，则第一UE将第一标志位的状态改变(在表1中以箭头“→”表示)为A。如果第一UE不符合第二条件，则将第一UE的第一标志位的状态改变为B。
在信令3中的第二字段的取值为001的情况下，如果第一UE符合第二条件，则第一UE将第一标志位的状态改变为A。如果第一UE不符合第二条件，则不改变第一UE的第一标志位的状态。
在信令3中的第二字段的取值为010的情况下，如果第一UE符合第二条件，则第一UE不改变第一标志位的状态。如果第一UE不符合第二条件，则将第一UE的第一标志位的状态改变为B。
在信令3中的第二字段的取值为011的情况下，如果第一UE符合第二条件，则第一UE将第一UE的第一标志位的状态置为相反的状态，例如，申明改变为非申明，非申明改变为申明，或者，从A改变为B，或者从B改变为A。如果第一UE不符合第二条件，则第一UE不改变第一标志位的状态。需要说明的是，申明和非申明与第一标志位的类型无关，即一个UE的任意一个标志位的状态要么为申明，要么为非申明状态。
在信令3中的第二字段的取值为100的情况下，如果第一UE符合第二条件，则第一UE将第一UE的第一标志位的状态改变为B。如果第一UE不符合第二条件，则第一UE将第一标志位的状态改变为A。
在信令3中的第二字段的取值为101的情况下，如果第一UE符合第二条件，则第一UE将第一标志位的状态改变为B。如果第一UE不符合第二条件，则第一UE不改变第一标志位的状态。
在信令3中的第二字段的取值为110的情况下，如果第一UE符合第二条件，则第一UE不改变第一标志位的状态。如果第一UE不符合第二条件，则第一UE将第一标志位的状态改变为A。
在信令3中的第二字段的取值为111的情况下，如果第一UE符合第二条件，则第一UE不改变第一标志位的状态。如果第一UE不符合第二条件，则第一UE将第一标志位的状态置为相反状态，例如，申明改变为非申明，非申明改变为申明，或者，从A改变为B，或者从B改变为A。
在第一设备并未指示动作信息的情况下，第一UE无需执行S604的步骤，即S604的步骤是可选的。
S605，第一设备发送信令5。相应的，一个或多个UE从第一设备接收信令5。在本申请实施例中，以第一UE接收到信令5为例。信令5的含义可参照前文。
作为一个示例，信令5可以为前文的信令3或信令4。当信令5相当于前文信令3的情况下，即相当于信令3还指示了最大时间单元范围。当信令5相当于前文信令4的情况下，相当于信令4还指示了最大时间单元范围。
作为一个示例，信令5指示的最大时间单元范围可通过信令3或者信令4指示，这种情况下，无需执行S605，即S605为可选的步骤。
S606，第一UE向第一设备发送第一请求。相应的，第一设备接收来自第一UE的第一请求。第一请求的含义可参照前文论述的内容。
在本申请实施例中，是以第一UE可根据信令3，确定本次是否接入第一设备为例进 行介绍。确定是否接入第一设备的方式可参照前文示例6论述的内容，此处不再列举。
S607，第一UE向第一设备发送上行数据。
上行数据例如该第一UE的EPC等。
需要说明的是，S606-S607相当于完成了本次接入。S606-S607为第一UE本次接入第一设备的方式的一种示例，实际上第一UE本次接入第一设备的方式还有多种，当第一UE采用其他方式接入第一设备时，S606-S607可能无需执行，即S606-S607为可选的步骤。
S608，第一设备向第一UE发送信令7。相应的，第一UE接收来自第一设备的信令7。
信令7用于指示第一UE的最大时间单元范围。本申请实施例中的信令7又可以称为第八信令。
需要说明的是，信令7指示的最大时间单元范围与信令5指示的最大时间单元范围不同。其中，两个最大时间单元范围不同是指两个最大时间单元范围不完全重合，或者完全不重合。
第一设备确定本次已寻呼的UE的数量(又称为第一数量)，第一数量可理解为第一设备通过信令3实际寻呼(盘存、盘点或接入)的UE的数量，或者可理解为通过信令3和信令4实际寻呼的UE的数量，或者可以进一步理解为本次寻呼(即通过信令3寻呼，或者通过信令3和信令4寻呼)下已接入第一设备的UE的数量。碰撞的含义可参照前文。例如，第一设备可将成功解析的上行数据的数量确定为第一数量。如果第一数量大于或等于第一阈值，那么第一UE与其他UE发生碰撞的可能性更大，因此第一设备可发送信令7，从而减少UE之间的碰撞，有利于提高通信的可靠性。
或者，第一设备在接收第一UE的上行数据之后，确定无法正确解析该上行数据，那么第一设备确定该第一UE可能与其他UE发生了碰撞，在这种情况下，第一设备可向第一UE发送信令7。
作为一个示例，第一设备也可不调整第一UE的最大时间单元范围，这种情况下，第一设备可不执行S608的步骤，即S608为可选的步骤。
S609，第一UE改变第一UE的第一标志位的状态。
在第一UE与第一设备之间完成本次通信(接入)之后，第一UE可改变其第一标志位的状态，从而降低第一设备在本次寻呼中触发该第一UE再次接入的可能性。例如，第一UE将第一标志位的状态从第一状态改变为第二状态。本次寻呼的含义可参照前文。
S610，第一设备发送信令8。相应的，一个或多个UE接收来自第一设备的信令8。在本申请实施例中是以第二UE接收信令8为例。信令8用于指示下一次待接入的UE的第二标志位的信息。第二标志位的信息用于指示第二标志位的类型为第二类型和/或第二标志位的状态为第二状态。第二类型和第一类型可不同，第二状态和第一状态也可不同。本申请实施例中的信令8又可以称为第三信令。
在信令2指示第一设备进行多次寻呼的情况下，第一设备在完成一次寻呼之后，可继续发起下一次寻呼。在本申请实施例中，第一设备可根据第一数量，确定下一次寻呼的UE的标志位的类型，和/或标志位的状态。第一数量的含义可参照前文。
示例性的，如果第一数量大于或等于第一阈值，表示之前已寻呼的UE的数量过多，而寻呼的UE的数量过多，容易引起UE之间的碰撞，因此第一设备确定下一次寻呼的UE的第二标志位的类型调整为第二类型，和/或第二标志位的状态调整为第二状态。如果第一数量小于第一阈值，表示之前寻呼的UE的数量相对合适，则第一设备确定下一次寻呼的 UE的标志位的类型为第一类型，和/或标志位的状态为第一状态。在图6所示的实施例中，以下一次寻呼的UE的第二标志位的类型为第二类型和/或标志位的状态为第二状态为例进行介绍。
在第二UE接收信令8之后，可根据信令8确定是否接入第一设备。根据信令8确定是否接入第一设备的方式可参照前文根据信令3确定是否接入第一设备的方式，此处不再列举。
作为一个示例，信令8可视为一个第二级寻呼信令。
需要说明的是，第一设备发起的两次寻呼所确定的待寻呼的UE可以是完全相同，部分相同或完全不同。例如，第一设备向第一UE发起寻呼，未成功接收来自第一UE的上行数据，第一设备可再次向第一UE发起寻呼。又例如，第一设备向第一UE发起寻呼，接收来自第一UE的上行数据，第一设备可向第二UE发起寻呼。又例如，第一设备向第一UE和第二UE发起寻呼，接收来自第一UE的上行数据，未接收来自第二UE的上行数据，第一设备可再次向第二UE发起寻呼。
作为一个示例，AMF可根据待寻呼的第一标志位的信息，确定第二设备待寻呼的UE的第二标志位的信息，并向第二设备发送信令6。信令6的含义、AMF确定第二标志位的信息的内容、第二标志位的信息的含义、第一设备和第二设备的关系、以及AMF发送信令6的时刻等相关内容均可参照前文图4所示的实施例论述的内容，此处不再列举。
作为一个示例，S604-S610的步骤均为可选的步骤。
在图6所示的实施例中，第一核心网设备(如AMF)可通过信令2间接指示第一类型和/或第一状态，第一设备可根据信令2，确定第一类型和/或第一状态，进而确定待寻呼的UE，提供了一种寻呼UE的机制。并且，由于无需具体确定待寻呼的UE具体是哪些，因此可简化寻呼过程。并且，第一设备可根据第一核心网设备的间接指示，确定第一类型和/或第一状态，使得第一设备本次寻呼既能满足业务需求，又无需第一核心网设备确定第一类型和/或第一状态，有利于减少第一核心网设备的处理量。另外，第一核心网设备可通过一个信令指示第一设备进行向UE发起多次寻呼，有利于减少第一设备与第一核心网设备之间的交互次数。
请参照图7，为本申请实施例提供的一种寻呼方法的流程示意图。图7中是以图4所示的实施例涉及的信令2不指示第一类型和/或第一状态为例，以信令3指示第一类型为例，以图4所示的实施例涉及的第一设备自行确定待寻呼的UE的标志位的信息(即采用上述方式二确定第一类型)为例进行介绍。

S703，第一设备发送信令3。相应的，一个或多个UE接收来自第一设备的信令3。信令3用于指示待寻呼的UE的标志位的类型为第一类型。
在本申请实施例中，以信令2没有指示第一类型为例进行介绍。这种情况下，第一设备可自行确定第一类型。其中，第一设备确定第一类型可采用前文子方式A1至子方式A3中的任意一种子方式，本申请实施例对此不做限定。
例如，第一设备将第一标志位的类型的状态确定为初始状态。
又例如，第一设备将第一标志位的类型的状态确定为初始状态，并将第一状态确定为第一标志位的初始状态。换言之，相当于第一设备选择该第一状态的UE接入。
在本申请实施例中，信令3还用于指示动作信息。动作信息的含义、以及第一设备确定动作信息的方式可参照前文。
可选的，信令3还用于指示掩码信息。

作为一个示例，第一设备可无需执行S704-S710的步骤，即S704-S710为可选的步骤。
在图7所示的实施例中，第一核心网设备(如AMF)无需指示第一类型和/或第一状态，第一设备可自行确定第一类型和/或第一状态，从而寻呼UE，提供了一种寻呼UE的机制。并且，由于无需具体确定待寻呼的UE，可简化寻呼UE的过程。并且，第一设备可自行确定第一类型和/或第一状态，减少了第一核心网设备的处理量。并且，第一设备可根据信令3确定待寻呼的UE，并通过信令4确定本次接入的UE，使得第一设备可灵活地确定待寻呼的UE的标志位的状态。另外，第一设备还可根据本次寻呼UE的情况，调整下一次寻呼UE的标志位的类型和/或标志位的状态，有利于第一设备确定更符合业务需求的UE，也提高了第一设备触发UE接入的灵活性。
