请参考图1，其示出了本公开实施例提供的一种无线通信系统的结构示意图。如图1所示，无线通信系统是基于移动通信技术的通信系统，该无线通信系统可以包括：若干个用户设备110以及若干个基站120。
其中，用户设备110可以是指向用户提供语音和/或数据连通性的设备。用户设备110可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，用户设备110可以是物联网用户设备，如传感器设备、移动电话和具有物联网用户设备的计算机，例如，可以是固定式、便携式、袖珍式、手持式、计算机内置的或者车载的装置。例如，站(Station，STA)、订户单元(subscriber unit)、订户站(subscriber station)，移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点、远程用户设备(remote terminal)、接入用户设备(access terminal)、用户装置(user terminal)、用户代理(user agent)、用户设备(user device)、或用户设备(user equipment)。或者，用户设备110也可以是无人飞行器的设备。或者，用户设备110也可以是车载设备，比如，可以是具有无线通信功能的行车电脑，或者是外接行车电脑的无线用户设备。或者，用户设备110也可以是路边设备，比如，可以是具有无线通信功能的路灯、信号灯或者其它路边设备等。
基站120可以是无线通信系统中的网络侧设备。其中，该无线通信系统可以是第四代移动通信技术(the 4th generation mobile communication，4G)系统，又称长期演进(Long Term Evolution，LTE)系统；或者，该无线通信系统也可以是5G系统，又称新空口系统或5G NR系统。或者，该无线通信系统也可以是5G系统的再下一代系统。其中，5G系统中的接入网可以称为NG-RAN(New Generation-Radio Access Network，新一代无线接入网)。
其中，基站120可以是4G系统中采用的演进型基站(eNB)。或者，基站120也可以是5G系统中采用集中分布式架构的基站(gNB)。当基站120采用集中分布式架构时，通常包括集中单元(central unit，CU)和至少两个分布单元(distributed unit，DU)。集中单元中设置有分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)层、无线链路层控制协议(Radio Link Control，RLC)层、媒体访问控制(Media Access Control，MAC)层的协议栈；分布单元中设置有物理(Physical，PHY)层协议栈，本公开实施例对基站120的具体实现方式不加以限定。
基站120和用户设备110之间可以通过无线空口建立无线连接。在不同的实施方式中，该无线空口 是基于第四代移动通信网络技术(4G)标准的无线空口；或者，该无线空口是基于第五代移动通信网络技术(5G)标准的无线空口，比如该无线空口是新空口；或者，该无线空口也可以是基于5G的更下一代移动通信网络技术标准的无线空口。
在一些实施例中，用户设备110之间还可以建立E2E(End to End，端到端)连接。比如车联网通信(vehicle to everything，V2X)中的V2V(vehicle to vehicle，车对车)通信、V2I(vehicle to Infrastructure，车对路边设备)通信和V2P(vehicle to pedestrian，车对人)通信等场景。
这里，上述用户设备可认为是下面实施例的终端设备。
在一些实施例中，上述无线通信系统还可以包含网络管理设备130。
若干个基站120分别与网络管理设备130相连。其中，网络管理设备130可以是无线通信系统中的核心网设备，比如，该网络管理设备130可以是演进的数据分组核心网(Evolved Packet Core，EPC)中的移动性管理实体(Mobility Management Entity，MME)。或者，该网络管理设备也可以是其它的核心网设备，比如服务网关(Serving GateWay，SGW)、公用数据网网关(Public Data Network GateWay，PGW)、策略与计费规则功能单元(Policy and Charging Rules Function，PCRF)或者归属签约用户服务器(Home Subscriber Server，HSS)等。对于网络管理设备130的实现形态，本公开实施例不做限定。
为了便于本领域内技术人员理解，本公开实施例列举了多个实施方式以对本公开实施例的技术方案进行清晰地说明。当然，本领域内技术人员可以理解，本公开实施例提供的多个实施例，可以被单独执行，也可以与本公开实施例中其他实施例的方法结合后一起被执行，还可以单独或结合后与其他相关技术中的一些方法一起被执行；本公开实施例并不对此作出限定。
为了更好地理解本公开任一个实施例所描述的技术方案，首先，对相关技术中分组寻呼终端的场景进行说明：
在一个实施例中，若不进行寻呼的分组，则在寻呼时刻所有终端都会被唤醒。在一个实施例中，由于在寻呼时刻对应时间段内的终端被寻呼的概率是不同的，则低寻呼概率的终端也会被错误唤醒，造成不必要的耗电。因此，需要对终端进行寻呼分组，采用寻呼分组的方式寻呼终端。
在一个实施例中，寻呼的分组信息可以携带在寻呼下行控制信息(DCI，Downlink Control Information)中，也可以携带在寻呼提前指示(PEI，Paging Early Indication)中。不管采用何种分组方式，终端和网络(包括基站和核心网)都需要对终端所在的分组达成一致，才能将寻呼消息正常发送给终端。
在一个实施例中，提供一种根据UE-ID取模确定分组的随机方式，可以按照UE-ID取模方式得到一个寻呼分组group，其公式为：
Figure PCTCN2021134688-appb-000001
其中，N w为总的寻呼分组资源数目，wg是选择的寻呼分组资源的索引。
其中，UE-ID取模方式为随机选择或者随机分配方式。即在所有的寻呼分组资源中按照UE-ID取模。这里，N是时间域上的寻呼帧密度，而Ns为时间域上一个寻呼帧内的寻呼密度；Nn为寻呼窄带； Nw为总的寻呼分组资源数目。
在一个实施例中，网络配置终端寻呼分组的方式，可以是由核心网执行。这里，不同于LTE中分配概率的方式，而是在NR中直接分配分组ID。此时网络在分配该分组ID的时候，将基于实现分配。例如，根据终端属性或者统计的寻呼概率进行分配等。
在一个实施例中，若核心网不给终端提供分组ID，则终端将回落到UE-ID的随机方式选择寻呼分组资源。
因此，可以认为有两种寻呼分组方式，一种基于网络分配的，而另外一种，则是UE-ID的随机方式。在一个实施例中，基站是需要通知终端支持何种方式，便于基站和终端在确定哪个分组并选择寻呼分组资源，以达到一致性。如果两种方式都不支持，则终端将根据不支持寻呼分组方式进行寻呼监听。
在一个实施例中，基站可以同时支持两种分组方式且两种分组方式的分组是没有重叠的。因此，会存在基站支持的用于核心网的分组的分组总数不足以支持核心网的最大分组，因此，就可能需要基站考虑如何将核心网的分组映射到基站能够支持的Lay1的分组。
如图2所示，本实施例中提供一种分组寻呼的方法，其中，该方法由基站执行，该方法包括：
步骤21、向终端发送映射关系信息；
其中，映射关系信息，指示寻呼分组的信息和寻呼分组资源之间的映射关系。
在一个实施例中，映射关系信息可以是用于终端确定寻呼分组的信息和寻呼分组资源之间的映射关系。如此，可以指示终端如何将寻呼分组映射至寻呼分组资源。
在一个实施例中，可以是根据基于预定方式分配的寻呼分组的数量和基站支持的用于预定方式的寻呼分组的数量，确定是否向终端发送映射关系信息，其中，预定方式为网络分配寻呼分组的方式。
这里，该终端可以是但不限于是手机、可穿戴设备、车载终端、路侧单元(RSU，Road Side Unit)、智能家居终端、工业用传感设备和/或医疗设备等。
本公开中涉及的基站可以是终端接入网络的接入设备。这里，基站可以为各种类型的基站，例如，第三代移动通信(3G)网络的基站、第四代移动通信(4G)网络的基站、第五代移动通信(5G)网络的基站或其它演进型基站。这里，基站可以是同时支持网络分配寻呼分组的方式和随机分配寻呼分组的方式。
在一个实施例中，分组寻呼可以是：将终端分成不同的分组；网络通过发送一个组寻呼消息来寻呼一个分组内的所有终端，而不需要针对每个终端单独发送寻呼消息；终端在接收到组呼消息后，判断自己是否属于被寻呼的分组；如果属于被寻呼的分组，则响应组呼消息，如果不属于被寻呼的分组，则忽略该组呼消息。
在一个实施例中，分组寻呼的分组可以是多个。这里，不同的分组可以是配置有不同的寻呼资源。终端可以是属于多个分组中的某一个分组。响应于终端所属的寻呼分组确定，则终端可以在寻呼分组指示的寻呼资源上进行寻呼消息的监听。这里，终端属于哪个分组可以是基于UE-ID取模方式确定的或者是核心网中的某个核心网设备确定的。需要说明的是，预定分组还可以被划分为多个子寻呼分组。当然，这里的分组可以就是指子寻呼分组，在此不做限定。本公开中的寻呼分组可以就是分组寻呼的分组。
在一个实施例中，基于预定方式分配的寻呼分组的数量和基站支持的用于预定方式的寻呼分组的数量不相同。在一个实施例中，如果基于预定方式分配的寻呼分组的数量大于基站支持的用于预定方式的寻呼分组的数量，确定向终端发送映射关系信息；或者，如果基于预定方式分配的寻呼分组的数量不大于基站支持的用于预定方式的寻呼分组的数量，确定不向所述终端发送所述映射关系信息。需要说明的是，如果基于预定方式分配的寻呼分组的数量不大于基站支持的用于预定方式的寻呼分组的数量，也可以确定向所述终端发送所述映射关系信息。
这里，基站支持的用于预定方式的寻呼分组的数量可以是与能够提供的寻呼分组的资源数量对应。可以理解的是，术语“大于”也涵盖了“大于等于”的含义，“小于”也涵盖了“小于等于”的含义。
在一个实施例中，基于预定方式分配的寻呼分组的数量可以是核心网分配的，基站可以接收核心网发送的基于预定方式分配的寻呼分组的数量。根据基于预定方式分配的寻呼分组的数量和基站支持的用于预定方式的寻呼分组的数量，确定是否向终端发送映射关系信息。这里，基于预定方式分配的寻呼分组的数量可以理解为网络分配的寻呼分组的最大数量。
在一个实施例中，基站支持的用于预定方式分配的寻呼分组的数量可以是由基站分配的。基站在确定分配的用于预定方式的寻呼分组的数量后，根据基于预定方式分配的寻呼分组的数量和基站支持的用于预定方式的寻呼分组的数量，确定是否向终端发送映射关系信息。
需要说明的是，基站支持的用于预定方式的寻呼分组的数量为根据预定协议规则确定的数量；或者，基站支持的用于预定方式的寻呼分组的数量为基站所支持的寻呼分组的总数。示例性地，基站支持的寻呼分组可以是支持的Lay1的寻呼分组。
在一个实施例中，数量信息，可以指示基站支持网络分配寻呼分组的方式。即在终端接收到数量信息后，可以基于该数量信息确定基站支持基于预定方式配置寻呼分组的方式。
在一个实施例中，基站在确定基站支持的用于预定方式的寻呼分组的数量后，可以向终端发送数据信息。示例性地，可以是向终端发送第一数量信息，其中，第一数量信息携带基站支持的用于预定方式的寻呼分组的数量值。例如，数量值N＝4，如此，第一数量信息可以显性指示基站支持的用于预定方式的寻呼分组的数量。或者，可以向终端发送第二数量信息，其中，第二数量信息指示使终端基于目标方式获得的数量确定基站支持的用于预定方式的寻呼分组的数量。例如，支持通过随机分组的方式(如UE-ID取模方式，为目标方式)和网络分配的方式(为预定方式)确定寻呼分组，基站支持的基于不同方式获得的寻呼分组的最大数量为8，则终端在确定通过随机分组的方式确定的寻呼分组的数量为4后，则终端可以确定基于网络分配的寻呼分组为4。如此，第二数量信息可以隐性指示基站支持的用于预定方式的寻呼分组的数量为4。在一个实施例中，第二数据信息的信息域指示预定值时，指示使终端基于目标方式获得的数量确定基站支持的用于预定方式的寻呼分组的数量。
在一个实施例中，基站向终端发送基站支持的用于预定方式的寻呼分组的数量，用于终端确定寻呼分组信息和寻呼分组资源之间的映射关系；在获取到该寻呼分组的数量后，终端可以通过协议约定来建立寻呼分组信息和寻呼分组资源之间的映射关系。
在一个实施例中，若基站能够确定核心网分配的最大寻呼分组数量，而基站也可以提供足够的寻呼分组数量以支持该分组方式，则基站仅需要通知终端基站可以提供支持的用于预定方式的寻呼分组的数 量即可。例如，基站通知的数量为8；则从核心网分配的最大寻呼分组的数量不会超过8，则终端按照一对一映射始终可以找到对应的寻呼分组资源；又例如，基站通过一个显式指示(比如一个flag指示)通知终端基站可以提供支持的用于预定方式的寻呼分组的数量，则终端按照一对一映射始终可以找到对应的寻呼分组资源。
在一个实施例中，基站可以仅提供寻呼分组数以支持该寻呼分组方式。例如，基站通知的寻呼分组数量为4；则从核心网分配的最大寻呼分组数量可能超过4或者不超过4。则终端按照一对一映射始终可以找到对应的寻呼分组资源。例如，此时若核心网分配的寻呼分组数量最大不超过4，则终端可以按照一一映射找到对应的寻呼分组资源；若核心网分配的寻呼分组数量超过4，则终端将超过的寻呼分组映射到最后一个寻呼分组资源即可。需要说明的是，最后一个寻呼分组资源可以是排序靠后的寻呼分组资源。
在一个实施例中，基站向终端发送基站支持的用于预定方式的寻呼分组的数量和基于网络分配的寻呼分组的数量，用于终端确定寻呼分组信息和寻呼分组资源之间的映射关系；在接收到该寻呼分组的数量后，终端通过协议约定来建立寻呼分组信息和寻呼分组资源之间的映射关系。
示例性地，基站支持的寻呼分组的数量为第一寻呼分组和第二寻呼分组共2个。核心网分配的寻呼分组的数量为4个，分别为第一寻呼分组、第二寻呼分组、第三寻呼分组和第四寻呼分组。可以是将第一寻呼分组、第二寻呼分组分别映射到第1和第2寻呼分组资源，将剩余的2个寻呼分组映射到最后一个寻呼分组资源。
在一个实施例中，预定映射关系可以是根据公式映射确定的映射关系。示例性地，可以按照均分方式确定寻呼分组对应的寻呼分组资源。
示例性地，基站支持的寻呼分组的数量为第一寻呼分组和第二寻呼分组，共2个，对应了2个寻呼分组资源。寻呼分组资源的数量为8个，分别为第一寻呼分组资源、第二寻呼分组资源、…第八寻呼分组资源。则可以均分寻呼分组资源，将第一寻呼分组资源至第四寻呼分组资源映射到第一寻呼分组，将第五寻呼分组资源至第八寻呼分组资源映射到第二寻呼分组。需要说明的是，不限于上述均分方式，也可以是均分任意选取的寻呼分组资源用于分配给第一寻呼分组和第二寻呼分组。
示例性地，基站支持的寻呼分组的数量为第一寻呼分组和第二寻呼分组共2个，对应了2个寻呼分组资源。寻呼分组的数量为7个，分别为第一寻呼分组、第二寻呼分组、…第七寻呼分组。则可以将第一寻呼分组至第四寻呼分组映射到第一寻呼分组资源，将剩余3个映射到第二寻呼分组资源。需要说明的是，不限于上述均分方式，也可以是均分任意选取的寻呼分组资源用于分配给第一寻呼分组和第二寻呼分组。
示例性地，基站支持的寻呼分组的数量为第一寻呼分组和第二寻呼分组共2个，对应了2个寻呼分组资源。寻呼分组的数量为7个，分别为第一寻呼分组、第二寻呼分组、…第七寻呼分组。则可以将第一寻呼分组至第3寻呼分组映射到第一寻呼分组资源，将剩余4个映射到第二寻呼分组资源。需要说明的是，不限于上述均分方式，也可以是均分任意选取的寻呼分组用于分配给第一寻呼分组和第二寻呼分组。
以上实施例中，基站均不需要提供显式指示的映射关系，仅需提供基站支持的用于预定方式的寻呼 分组的数量和/或基于网络分配的寻呼分组的数量，以用于终端确定映射关系。
在一个实施例中，建立寻呼分组信息和寻呼分组资源之间的映射关系。根据基于预定方式分配的寻呼分组的数量和基站支持的用于预定方式的寻呼分组的数量，确定是否向终端发送映射关系信息。这里，映射关系信息指示映射关系。
在一个实施例中，可以是建立单个寻呼分组和包括至少一个寻呼分组资源的资源集之间的映射关系。示例性地，映射关系可以是单个寻呼分组对应单个寻呼分组资源的关系。如表一所示：
表一：一对一的关系
寻呼分组 寻呼分组资源
Subgroup0 寻呼分组radio resource 0
Subgroup1 寻呼分组radio resource 1
… …
示例性地，映射关系可以是单个寻呼分组对应多个寻呼分组资源的关系。如表二所示：
表二：一对多的关系
Figure PCTCN2021134688-appb-000002
在一个实施例中，可以是建立包含多个寻呼分组的组集与包含至少一个寻呼分组资源的资源集之间的映射关系。示例性地，映射关系可以是多个寻呼分组对应多个寻呼分组资源的关系。如表三所示：
表三，多对多的关系
Figure PCTCN2021134688-appb-000003
以上实施例，即基站需要显式通知终端其映射关系。
在本公开实施例中，向终端发送映射关系信息，其中，映射关系信息，指示寻呼分组的信息和寻呼分组资源之间的映射关系。这里，由于可以向终端发送指示寻呼分组的信息和寻呼分组资源之间的映射关系的映射关系信息，如此，终端就可以基于映射关系确定出寻呼分组的寻呼分组资源，相较于在网络分配的寻呼分组的数量和基站支持的寻呼分组的数量不一致时无法确定出寻呼分组资源的情况，可以减少由于不能够确定出寻呼分组资源进行寻呼监听而导致的寻呼失败的情况，提升分组寻呼的可靠性。
需要说明的是，本领域内技术人员可以理解，本公开实施例提供的方法，可以被单独执行，也可以 与本公开实施例中一些方法或相关技术中的一些方法一起被执行。

或者，

这里，映射关系信息，指示寻呼分组的信息和寻呼分组资源之间的映射关系。
在一个实施例中，基站在获取到基于预定方式分配的寻呼分组的数量和确定基站支持的用于预定方式的寻呼分组的数量后，会比较基于预定方式分配的寻呼分组的数量和基站支持的用于预定方式的寻呼分组的数量的大小。示例性地，当基于预定方式分配的寻呼分组的数量大于基站支持的用于预定方式的寻呼分组的数量，确定向终端发送映射关系信息；或者，当基于预定方式分配的寻呼分组的数量不大于基站支持的用于预定方式的寻呼分组的数量，确定不向终端发送所述映射关系信息。需要说明的是，如果基于预定方式分配的寻呼分组的数量不大于基站支持的用于预定方式的寻呼分组的数量，也可以确定向所述终端发送映射关系信息，在本公开中，不做限定。
在一个实施例中，基站预先建立寻呼分组的信息和寻呼分组资源之间的映射关系。在映射关系建立好后，响应于基于预定方式分配的寻呼分组的数量大于基站支持的用于预定方式的寻呼分组的数量，确定向终端发送映射关系信息；或者，响应于基于预定方式分配的寻呼分组的数量不大于基站支持的用于预定方式的寻呼分组的数量，确定不向终端发送所述映射关系信息。需要说明的是，如果基于预定方式分配的寻呼分组的数量不大于基站支持的用于预定方式的寻呼分组的数量，也可以确定向终端发送所述映射关系信息，在本公开中，不做限定。
在一个实施例中，向终端发送映射关系信息可以是向终端广播映射关系信息。

本公开中涉及的基站可以是终端接入网络的接入设备。这里，基站可以为各种类型的基站，例如，第三代移动通信(3G)网络的基站、第四代移动通信(4G)网络的基站、第五代移动通信(5G)网络的基站或其它演进型基站。这里，基站可以是同时支持网络分配寻呼分组的方式和随机分配寻呼分组的方式。
在一个实施例中，分组寻呼可以是：将终端分成不同的分组；网络通过发送一个组寻呼消息来寻呼一个分组内的所有终端，而不需要针对每个终端单独发送寻呼消息；终端在接收到组呼消息后，判断自己是否属于被寻呼的分组；如果属于被寻呼的分组，则响应组呼消息，如果不属于被寻呼的分组，则忽略该组呼消息。
在一个实施例中，分组寻呼的分组可以是多个。这里，不同的分组可以是配置有不同的寻呼资源。终端可以是属于多个分组中的某一个分组。响应于终端所属的寻呼分组确定，则终端可以在寻呼分组指示的寻呼资源上进行寻呼消息的监听。这里，终端属于哪个分组可以是基于UE-ID取模方式确定的或 者是核心网中的某个核心网设备确定的。需要说明的是，预定分组还可以被划分为多个子寻呼分组。当然，这里的分组可以就是指子寻呼分组，在此不做限定。
在一个实施例中，预定方式为网络分配寻呼分组的方式。基于预定方式分配的寻呼分组的数量和基站支持的用于预定方式的寻呼分组的数量不相同。在一个实施例中，如果基于预定方式分配的寻呼分组的数量大于基站支持的用于预定方式的寻呼分组的数量，基站确定向终端发送映射关系信息；或者，如果基于预定方式分配的寻呼分组的数量不大于基站支持的用于预定方式的寻呼分组的数量，基站确定不向所述终端发送所述映射关系信息。需要说明的是，如果基于预定方式分配的寻呼分组的数量不大于基站支持的用于预定方式的寻呼分组的数量，基站也可以确定向所述终端发送所述映射关系信息。这里，基站支持的用于预定方式的寻呼分组的数量可以是与能够提供的寻呼分组的资源数量对应。可以理解的是，术语“大于”也涵盖了“大于等于”的含义，“小于”也涵盖了“小于等于”的含义。

需要说明的是，基站支持的用于预定方式的寻呼分组的数量为根据预定协议规则确定的数量；或者，基站支持的用于预定方式的寻呼分组的数量为基站所支持的寻呼分组的总数。示例性地，基站支持的寻呼分组可以是支持的Lay1的寻呼分组。
在一个实施例中，数量信息，可以指示基站支持网络分配寻呼分组的方式。即在终端接收到数量信息后，可以基于该数量信息确定基站支持基于预定方式配置寻呼分组的方式。
在一个实施例中，基站在确定基站支持的用于预定方式的寻呼分组的数量后，可以向终端发送数据信息。示例性地，可以是向终端发送第一数量信息，其中，第一数量信息携带基站支持的用于预定方式的寻呼分组的数量值。例如，数量值N＝4，如此，第一数量信息可以显性指示基站支持的用于预定方式的寻呼分组的数量。或者，可以向终端发送第二数量信息，其中，第二数量信息指示使终端基于目标方式获得的数量确定基站支持的用于预定方式的寻呼分组的数量。例如，支持通过随机分组的方式(如UE-ID取模方式，为目标方式)和网络分配的方式(为预定方式)确定寻呼分组，基站支持的基于不同方式获得的寻呼分组的最大数量为8，则终端在确定通过随机分组的方式确定的寻呼分组的数量为4后，则终端可以确定基于网络分配的寻呼分组为4。如此，第二数量信息可以隐性指示基站支持的用于预定方式的寻呼分组的数量为4。在一个实施例中，第二数据信息的信息域指示预定值时，指示使终端基于目标方式获得的数量确定基站支持的用于预定方式的寻呼分组的数量。
在一个实施例中，基站会建立寻呼分组信息和寻呼分组资源之间的映射关系。基站根据基于预定方式分配的寻呼分组的数量和基站支持的用于预定方式的寻呼分组的数量，确定是否向终端发送映射关系信息。这里，映射关系信息指示映射关系。
在一个实施例中，基站可以是建立单个寻呼分组和包括至少一个寻呼分组资源的资源集之间的映射关系。示例性地，映射关系可以是单个寻呼分组对应单个寻呼分组资源的关系。示例性地，映射关系可以是单个寻呼分组对应多个寻呼分组资源的关系。

这里，基站支持的用于预定方式的寻呼分组的数量为根据预定协议规则确定的数量；或者，基站支持的用于预定方式的寻呼分组的数量为基站所支持的寻呼分组的总数。

如图11所示，本实施例中提供一种分组寻呼的方法，其中，该方法由终端执行，该方法包括：
步骤111、根据终端所属寻呼分组和映射关系信息指示的映射关系，确定终端用于寻呼的寻呼分组资源；
或者，
根据终端所属寻呼分组和预定映射关系，确定终端用于寻呼的寻呼分组资源，其中，预定映射关系为预先配置的；在一个实施例中，预定映射关系为协议预先约定；
或者，
根据终端所属寻呼分组、映射关系信息指示的映射关系和/或预定映射关系确定终端用于寻呼的寻呼分组资源。
在一个实施例中，映射关系为顺序映射，具体请再参见表一。寻呼分组的排列顺序为Subgroup0、Subgroup1…；寻呼分组资源的排列顺序为radio resource 0、radio resource 1…；则Subgroup0映射到radio resource 0；Subgroup1映射到radio resource 1。如此，在终端确定终端所属寻呼分组后，就可以根据所属寻呼分组的信息，确定该寻呼分组映射的寻呼资源。
在一个实施例中，若出现寻呼分组资源不够，则按照默认方式进行映射。这里，默认方式可以是预定方式。
示例性地，基站支持的用于预定方式的寻呼分组的数量为第一寻呼分组和第二寻呼分组，共2个。寻呼分组的数量为4个，则分别将第一寻呼分组、第二寻呼分组分别映射到第1，2寻呼分组资源，将剩余的2个寻呼分组映射到最后一个寻呼分组资源。
在一个实施例中，预定映射关系可以是根据公式映射确定的映射关系。示例性地，可以按照均分方式确定寻呼分组对应的寻呼资源。
示例性地，基站支持的寻呼分组的数量为第一寻呼分组和第二寻呼分组共2个，对应了2个寻呼分组资源。寻呼分组的数量为8个，分别为第一寻呼分组、第二寻呼分组、…第八寻呼分组。则可以均分寻呼资源，将第一寻呼分组至第四寻呼分组映射到第一寻呼分组资源，将第五寻呼分组至第八寻呼分组映射到第二寻呼分组资源。需要说明的是，不限于上述均分方式，也可以是均分任意选取的寻呼分组用于分配给第一寻呼分组和第二寻呼分组。
示例性地，基站支持的寻呼分组的数量为第一寻呼分组和第二寻呼分组，共2个，对应了2个寻呼分组资源。寻呼分组的数量为7个，分别为第一寻呼分组、第二寻呼分组、…第七寻呼分组。则可以将第一寻呼分组至第四寻呼分组映射到第一寻呼分组资源，将剩余3个映射到第二寻呼分组资源。需要说明的是，不限于上述均分方式，也可以是均分任意选取的寻呼分组用于分配给第一寻呼分组和第二寻呼分组。
示例性地，基站支持的寻呼分组的数量为第一寻呼分组和第二寻呼分组共2个，对应了2个寻呼分组资源。寻呼分组的数量为7个，分别为第一寻呼分组、第二寻呼分组、…第七寻呼分组。则可以将第一寻呼分组至第3寻呼分组映射到第一寻呼分组资源，将剩余4个映射到第二寻呼分组资源。需要说明的是，不限于上述均分方式，也可以是均分任意选取的寻呼分组用于分配给第一寻呼分组和第二寻呼分组。
需要说明的是，当基站只支持一个寻呼分组时，可以将所有寻呼资源分配给该单个寻呼分组。
在一个实施例中，当根据基站发送的映射关系信息指示的映射关系不能确定映射资源时，例如，基站支持的用于预定方式的寻呼分组的数量为a个，而基于预定方式分配的寻呼分组的数量为b个，其中，b大于a，且基站只广播了a个映射关系，则仍有(b-a)个寻呼分组不能够确定对应的寻呼资源，此时，可以基于预先配置好的预定映射关系确定剩余的(b-a)个寻呼分组的寻呼资源。
例如，基站仅仅广播了基站支持的寻呼分组的数量为3，则广播的映射关系也为3个，而基于预定方式分配的分组数的范围为8，则仅仅有3个寻呼分组可以基于映射关系找到寻呼资源，而其他的5个寻呼分组可以采用预定映射关系确定寻呼资源。
作为一种实施例，基站提供的显式指示的映射关系和协议约定的映射关系可以结合使用。
需要说明的是，本领域内技术人员可以理解，本公开实施例提供的方法，可以被单独执行，也可以与本公开实施例中一些方法或相关技术中的一些方法一起被执行。

在一个实施例中，寻呼分组的排列顺序为Subgroup0、Subgroup1…；寻呼分组资源的排列顺序为 radio resource 0、radio resource 1…；则Subgroup0映射到radio resource 0；Subgroup1映射到radio resource 1。如此，在终端确定终端所属寻呼分组后，就可以根据所属寻呼分组的信息，确定该寻呼分组映射的寻呼资源。
这里，随机选择方式可以是随机选择寻呼分组资源。
