候选小区配置的变更方法、装置、终端和网络设备
相关申请的交叉引用
本公开要求于2022年09月30日提交的申请号为202211216268.X，发明名称为“候选小区配置的变更方法、装置、终端和网络设备”的中国专利申请的优先权，其通过引用方式全部并入本文。
技术领域
本公开涉及通信技术领域，尤其涉及一种候选小区配置的变更方法、装置、终端和网络设备。
背景技术
目前，为了保证加入组播会话的终端能够获取较高的服务质量，仅支持终端在无线资源控制(Radio Resource Control，RRC)连接态基于组播配置接收组播业务。但考虑到组播业务接收需求，考虑后续可能会支持终端在RRC空闲态或RRC非激活态基于组播配置接收组播业务。
终端在RRC空闲态或RRC非激活态基于组播配置接收组播业务时，可能会额外配置多个候选小区配置，例如多个候选小区的组播配置或组播配置的多个适用候选小区。在候选小区配置发生变更的情况下，若终端仍基于之前的候选小区配置接收组播业务的业务数据，则会导致业务数据接收失败。

具体实施方式
本公开实施例中术语“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这三种情况。字符“/”一般表示前后关联对象是一种“或”的关系。
本公开实施例中术语“多个”是指两个或两个以上，其它量词与之类似。
本公开实施例提供的技术方案可以适用于多种系统，尤其是5G系统。例 如适用的系统可以是全球移动通讯(global system of mobile communication，GSM)系统、码分多址(code division multiple access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)通用分组无线业务(general packet radio service，GPRS)系统、长期演进(long term evolution，LTE)系统、LTE频分双工(frequency division duplex，FDD)系统、LTE时分双工(time division duplex，TDD)系统、高级长期演进(long term evolution advanced，LTE-A)系统、通用移动系统(universal mobile telecommunication system，UMTS)、全球互联微波接入(worldwide interoperability for microwave access，WiMAX)系统、5G新空口(New Radio,NR)系统等。这多种系统中均包括终端设备和网络设备。系统中还可以包括核心网部分，例如演进的分组系统(Evloved Packet System,EPS)、5G系统(5GS)等。
其中，本公开实施例涉及的终端，可以是指向用户提供语音和/或数据连通性的设备，具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备等。在不同的系统中，终端的名称可能也不相同，例如在5G系统中，终端可以称为用户设备(User Equipment，UE)。无线终端设备可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网(Core Network，CN)进行通信，无线终端设备可以是移动终端设备，如移动电话(或称为“蜂窝”电话)和具有移动终端设备的计算机，例如，可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语言和/或数据。例如，个人通信业务(Personal Communication Service，PCS)电话、无绳电话、会话发起协议(Session Initiated Protocol，SIP)话机、无线本地环路(Wireless Local Loop，WLL)站、个人数字助理(Personal Digital Assistant，PDA)等设备。无线终端设备也可以称为系统、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(access point)、远程终端设备(remote terminal)、接入终端设备(access terminal)、用户终端设备(user terminal)、用户代理(user agent)、用户装置(user device)，本公开实施例中并不限定。
本公开实施例涉及的网络设备，可以是基站，该基站可以包括多个为终 端提供服务的小区。根据具体应用场合不同，基站又可以称为接入点，或者可以是接入网中在空中接口上通过一个或多个扇区与无线终端设备通信的设备，或者其它名称。网络设备可用于将收到的空中帧与网际协议(Internet Protocol，IP)分组进行相互更换，作为无线终端设备与接入网的其余部分之间的路由器，其中接入网的其余部分可包括网际协议(IP)通信网络。网络设备还可协调对空中接口的属性管理。例如，本公开实施例涉及的网络设备可以是全球移动通信系统(Global System for Mobile communications，GSM)或码分多址接入(Code Division Multiple Access，CDMA)中的网络设备(Base Transceiver Station，BTS)，也可以是带宽码分多址接入(Wide-band Code Division Multiple Access，WCDMA)中的网络设备(NodeB)，还可以是长期演进(long term evolution，LTE)系统中的演进型网络设备(evolutional Node B，eNB或e-NodeB)、5G网络架构(next generation system)中的5G基站(gNB)，也可以是家庭演进基站(Home evolved Node B，HeNB)、中继节点(relay node)、家庭基站(femto)、微微基站(pico)等，本公开实施例中并不限定。在一些网络结构中，网络设备可以包括集中单元(centralized unit，CU)节点和分布单元(distributed unit，DU)节点，集中单元和分布单元也可以地理上分开布置。
示例地，在本公开实施例中，网络设备与终端设备之间可以各自使用一或多根天线进行多输入多输出(Multi Input Multi Output，MIMO)传输，MIMO传输可以是单用户MIMO(Single User MIMO，SU-MIMO)或多用户MIMO(Multiple User MIMO，MU-MIMO)。根据根天线组合的形态和数量，MIMO传输可以是2D-MIMO、3D-MIMO、FD-MIMO或massive-MIMO，也可以是分集传输或预编码传输或波束赋形传输等。
目前，为了保证加入组播会话的终端能够获取较高的服务质量，仅支持终端在无线资源控制(Radio Resource Control，RRC)连接态基于组播配置接收组播业务。但考虑到组播业务接收需求，例如公共安全类型的组播业务等，需要较多的终端接收，考虑到终端所在的服务小区的网络资源有限，无法保证需要接收该类型组播业务的终端均处于RRC连接态，因此，考虑后续可能会支持终端在RRC空闲态或RRC非激活态基于组播配置接收组播业务。
终端在RRC空闲态或RRC非激活态基于组播配置接收组播业务时，可能 会额外配置多个候选小区配置，例如多个候选小区的组播配置或组播配置的多个适用候选小区。在候选小区配置发生变更的情况下，若终端仍基于更前的候选小区配置接收组播业务的业务数据，则会导致业务数据接收失败。
为了解决终端因基于变更前的候选小区配置接收组播业务导致的业务数据接收失败的问题，本公开实施例提供了一种候选小区配置的变更方法，终端通过接收网络设备发送的第一消息，第一消息中包括第一指示信息，第一指示信息用于表征处于空闲态或非激活态的终端候选小区配置的变更情况；并根据第一指示信息对候选小区配置进行处理；处理包括删除或变更，这样终端根据第一指示信息表征的候选小区配置的变更情况对候选小区配置进行处理，就可以有效地避免基于变更前的候选小区配置接收组播业务的业务数据，从而有效地解决了终端因基于变更前的候选小区配置接收组播业务导致的业务数据接收失败的问题。
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，并不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
图1为本公开实施例提供的候选小区配置的变更方法的流程示意图一，该候选小区配置的变更方法可应用于终端，例如，手机等。示例地，请参见图1所示，该候选小区配置的变更方法包括：
S101、接收网络设备发送的第一消息，第一消息中包括第一指示信息，第一指示信息用于表征处于空闲态或非激活态的终端候选小区配置的变更情况。
示例地，在本公开实施例中，候选小区配置包括至少一个候选小区的组播配置，和/或组播配置对应的初始适用的候选小区，具体可以根据实际需要进行设置，在此，本公开实施例只是以这两种候选小区配置为例进行说明，但并不代表本公开实施例仅局限于此。
示例地，当候选小区配置包括至少一个候选小区的组播配置时，第一指示信息用于表征处于空闲态或非激活态的终端至少一个候选小区的组播配置的变更情况，对应的第一消息可以包括寻呼消息，即网络设备可以将用于表征至少一个候选小区的组播配置的变更情况的第一指示信息携带在寻呼消息 中发送给终端，对应的，终端通过接收寻呼消息获取第一指示信息。
示例地，当候选小区配置包括组播配置对应的初始适用的候选小区时，第一指示信息用于表征处于空闲态或非激活态的终端组播配置对应的变更后适用的目标候选小区，对应的第一消息可以包括系统信息、组播/广播业务控制信道、或者寻呼消息中的至少一种，即网络设备可以将用于表征变更后的目标候选小区的第一指示信息携带在系统信息、组播/广播业务控制信道、或者寻呼消息中的至少一种发送给终端，对应的，终端通过接收系统信息、组播/广播业务控制信道、或者寻呼消息中的至少一种获取用于表征变更后的目标候选小区的第一指示信息。
终端根据第一指示信息确定处于空闲态或非激活态的终端候选小区配置的变更情况后，就可以执行下述S102：
S102、终端根据第一指示信息对候选小区配置进行处理；处理包括删除或变更。
示例地，在本公开实施例中，当候选小区配置包括至少一个候选小区的组播配置时，可以根据第一指示信息表征的至少一个候选小区的组播配置的变更情况，对至少一个候选小区的组播配置进行删除处理或变更处理；当候选小区配置包括组播配置对应的初始适用的候选小区时，可以根据第一指示信息表征的组播配置对应的变更后的目标候选小区，对组播配置对应的初始适用的候选小区进行变更处理，后续将进行详细说明。
可以看出，本公开实施例中，终端通过接收网络设备发送的第一消息，第一消息中包括第一指示信息，第一指示信息用于表征处于空闲态或非激活态的终端候选小区配置的变更情况；并根据第一指示信息对候选小区配置进行处理；处理包括删除或变更，这样终端根据第一指示信息表征的候选小区配置的变更情况对候选小区配置进行处理，就可以有效地避免基于变更前的候选小区配置接收组播业务的业务数据，从而有效地解决了终端因基于变更前的候选小区配置接收组播业务导致的业务数据接收失败的问题。
基于上述图1所示的实施例，候选小区配置可以包括至少一个候选小区的组播配置，和/或组播配置对应的初始适用的候选小区。为了便于理解本公开的技术方案，下面，将结合不同内容的候选小区配置，对上述终端如何根据第一指示信息对候选小区配置进行处理的技术方案进行详细描述。
示例地，在一种场景中，候选小区配置包括至少一个候选小区的组播配置，该种场景可以理解为：网络设备在确定终端至少一个候选小区的组播配置发生变更的情况下，向终端发送寻呼消息，寻呼消息包括第一指示信息，第一指示信息用于表征至少一个候选小区的组播配置的变更情况，使得终端可以根据第一指示信息表征的至少一个候选小区的组播配置的变更情况，对至少一个候选小区的组播配置进行处理。
在该种场景中，第一指示信息表征至少一个候选小区的组播配置的变更情况时，可以通过多种方式进行表征。示例地，在本公开实施例中，第一指示信息可以用于表征至少一个候选小区的组播配置存在变更，也可以表征组播配置变更的目标候选小区的标识等，具体可以根据实际需要进行设置，在此，本公开实施例只是以这两种表征方式进行说明，但并不代表本公开实施例仅局限于此。
示例地，在一种可能的实现方式中，当第一指示信息表征至少一个候选小区的组播配置存在变更时，考虑到并未明确具体存在变更的组播配置，因此，在该种可能的实现方式中，终端在空闲态或非激活态，可以根据该第一指示信息删除至少一个候选小区的组播配置，可参见下述实施例1，这样终端在空闲态或非激活态，根据第一指示信息表征的组播配置存在变更直接删除至少一个候选小区的组播配置，可以有效地避免基于变更前的至少一个候选小区的组播配置接收组播业务的业务数据，从而有效地解决了终端因基于变更前的候选小区配置接收组播业务导致的业务数据接收失败的问题。此外，终端在空闲态或非激活态，根据第一指示信息表征的组播配置存在变更直接删除至少一个候选小区的组播配置，无需因更新变更的组播配置而触发从空闲态或非激活态进入连接态，从而解决了终端因更新变更的组播配置触发从空闲态或非激活态进入连接态，造成的终端状态频繁切换的问题。
实施例1
步骤1、网络设备向终端配置至少一个候选小区的组播配置。
终端在服务小区处于连接态接收组播业务，由于服务小区拥塞等原因，网络设备可以向终端发送RRC释放消息，将终端释放到空闲态或非激活态继续接收组播业务。
终端被释放到空闲态或非激活态之前，网络设备会向终端配置至少一个 候选小区的组播配置。示例地，网络设备在向终端配置至少一个候选小区的组播配置时，可以在终端处于连接态时，通过RRC重配消息向终端配置至少一个候选小区的组播配置；也可以在释放终端到空闲态或非激活态的过程中，通过RRC释放消息向终端配置至少一个候选小区的组播配置，具体可以根据实际需要进行设置。
示例地，候选小区的组播配置可以包括候选小区1对应的组播配置config1、候选小区2对应的组播配置config2，……，以及候选小区5对应的组播配置config5。
步骤2、网络设备在确定至少一个候选小区的组播配置存在变更的情况下，向终端发送组寻呼消息，组寻呼消息中包含第一指示信息，第一指示信息表征处于空闲态或非激活态的终端至少一个候选小区的组播配置存在变更。
示例地，第一指示信息可以采用1比特的值进行指示。例如，第一指示信息为0时，可以理解为至少一个候选小区的组播配置未存在变更，第一指示信息为1时，可以理解为至少一个候选小区的组播配置存在变更；或者，第一指示信息为0时，可以理解为至少一个候选小区的组播配置存在变更，第一指示信息为1时，可以理解为至少一个候选小区的组播配置未存在变更，具体可以根据实际需要进行设置。
步骤3、终端在空闲态或非激活态，根据第一指示信息表征的组播配置存在变更，删除至少一个候选小区的组播配置。
在该步骤3中，以候选小区的组播配置包括候选小区1对应的组播配置config1、候选小区2对应的组播配置config2，……，以及候选小区5对应的组播配置config5为例，终端接收到用于表征组播配置存在变更的第一指示信息后，可以在空闲态或非激活态，直接根据第一指示信息删除候选小区的组播配置，即终端删除候选小区1对应的组播配置config1、候选小区2对应的组播配置config2，……，以及候选小区5对应的组播配置config5。
示例地，在另一种可能的实现方式中，当第一指示信息表征组播配置变更的目标候选小区的标识时，考虑到已经明确地指示了组播配置变更的目标候选小区的标识，因此，在该种可能的实现方式中，终端在空闲态或非激活态，可以根据目标候选小区的标识删除目标候选小区的组播配置，可参见下 述实施例2，这样终端在空闲态或非激活态，根据第一指示信息表征的目标候选小区的标识直接删除目标候选小区的组播配置，就可以有效地避免基于变更前的目标候选小区的组播配置接收组播业务的业务数据，从而有效地解决了终端因基于变更前的目标候选小区的组播配置接收组播业务导致的业务数据接收失败的问题。此外，终端在空闲态或非激活态直接删除目标候选小区的组播配置，无需因更新目标候选小区的组播配置而触发从空闲态或非激活态进入连接态，从而解决了终端因更新目标候选小区的组播配置触发从空闲态或非激活态进入连接态，造成的终端状态频繁切换的问题。
实施例2
步骤1、网络设备向终端配置至少一个候选小区的组播配置。
终端在服务小区处于连接态接收组播业务，由于服务小区拥塞等原因，网络设备可以向终端发送RRC释放消息，将终端释放到空闲态或非激活态继续接收组播业务。
需要说明的是，该步骤1中的实现方式与上述实施例1中步骤1的实现方式类似，可参见上述实施例1中步骤1的相关描述，在此，本公开实施例不再进行赘述。
步骤2、网络设备在确定至少一个候选小区的组播配置存在变更的情况下，向终端发送组寻呼消息，组寻呼消息中包含第一指示信息，第一指示信息表征处于空闲态或非激活态的终端组播配置变更的目标候选小区的标识。
示例地，第一指示信息可以采用比特位bitmap进行指示。例如，第一指示信息为{10000}时，目标候选小区为候选小区1，可以理解为候选小区1对应的组播配置config1发生变更；第一指示信息为{10100}时，目标候选小区包括候选小区1和候选小区3，可以理解为候选小区1对应的组播配置config1和候选小区3对应的组播配置config3发生变更。
步骤3、终端在空闲态或非激活态，根据第一指示信息表征的目标候选小区的标识删除至少目标候选小区的组播配置。
在该步骤3中，以第一指示信息为{10100}为例，终端接收到用于表征组播配置变更的候选小区1的标识和候选小区3的标识的第一指示信息后，可以根据第一指示信息删除候选小区1对应的组播配置config1和候选小区3对应的组播配置config3。
基于上述可能的实现方式，当第一指示信息表征组播配置变更的目标候选小区的标识时，终端在空闲态或非激活态根据目标候选小区的标识删除目标候选小区的组播配置，还可以结合网络设备发送的候选小区更新列表，共同确定是否根据目标候选小区的标识删除目标候选小区的组播配置。
其中，候选小区更新列表为至少一个候选小区的子集，候选小区更新列表中的候选小区可以理解为：网络设备期望终端触发状态转换进入连接态，并在连接态更新组播配置变更的候选小区。
示例地，在结合网络设备发送的候选小区更新列表，共同确定是否根据目标候选小区的标识删除目标候选小区的组播配置时，可以判断第一指示信息表征的组播配置变更的目标候选小区的标识是否包括在候选小区更新列表内，在确定候选小区更新列表未包括目标候选小区的情况下，说明目标候选小区不是网络设备期望终端更新组播配置变更的候选小区，则终端可以在空闲态或非激活态，根据目标候选小区的标识删除目标候选小区的组播配置，可参见下述实施例3，这样就可以有效地避免基于变更前的目标候选小区的组播配置接收组播业务的业务数据，从而有效地解决了终端因基于变更前的目标候选小区的组播配置接收组播业务导致的业务数据接收失败的问题。此外，终端在空闲态或非激活态直接删除目标候选小区的组播配置，无需因更新目标候选小区的组播配置而触发从空闲态或非激活态进入连接态，从而解决了终端因更新目标候选小区的组播配置触发从空闲态或非激活态进入连接态，造成的终端状态频繁切换的问题。
在确定候选小区更新列表包括候选小区的情况下，说明目标候选小区是网络设备期望终端更新组播配置变更的候选小区，则终端触发从空闲态或非激活态进入连接态，并在连接态对目标候选小区的组播配置进行更新，可参见下述实施例4，就可以有效地避免基于变更前的目标候选小区的组播配置接收组播业务的业务数据，从而有效地解决了终端因基于变更前的目标候选小区的组播配置接收组播业务导致的业务数据接收失败的问题。此外，在该种情况下，终端虽然需要触发从空闲态或非激活态进入连接态，并在连接态对目标候选小区的组播配置进行更新，但是通过结合候选小区更新列表，只有在候选小区更新列表包括候选小区的情况下才进行状态切换，这样可以有效地降低终端状态的频次。
实施例3
步骤1、网络设备向终端配置至少一个候选小区的组播配置。
需要说明的是，该步骤1中的实现方式与上述实施例1中步骤1的实现方式类似，可参见上述实施例1中步骤1的相关描述，在此，本公开实施例不再进行赘述。
步骤2、网络设备向终端通知候选小区更新列表。
终端被释放到空闲态或非激活态之前，网络设备会向终端通知候选小区更新列表。示例地，网络设备会向终端通知候选小区更新列表时，可以在终端处于连接态时，通过RRC重配消息向终端通知候选小区更新列表；也可以在释放终端到空闲态或非激活态的过程中，通过RRC释放消息通知候选小区更新列表，具体可以根据实际需要进行设置。
可以理解的是，在本公开实施例中，当网络设备通过RRC重配消息，向终端通知至少一个候选小区的组播配置和候选小区更新列表时，可以通过一条RRC重配消息，一并向终端通知至少一个候选小区的组播配置和候选小区更新列表；也可以通过两条RRC重配消息，分别向终端通知至少一个候选小区的组播配置和候选小区更新列表。当网络设备通过RRC释放消息，向终端通知至少一个候选小区的组播配置和候选小区更新列表时，通常情况下，会通过一条RRC释放消息，一并向终端通知至少一个候选小区的组播配置和候选小区更新列表。
示例地，候选小区更新列表可以采用比特位bitmap进行指示。例如，候选小区更新列表为{01100}时，可以理解为网络设备期望终端触发状态转换进入连接态，并在连接态更新组播配置变更的候选小区包括候选小区2和候选小区3；第一指示信息为{10110}时，可以理解为网络设备期望终端触发状态转换进入连接态，并在连接态更新组播配置变更的候选小区包括候选小区1、候选小区3以及候选小区4。
步骤3、网络设备在确定至少一个候选小区的组播配置存在变更的情况下，向终端发送组寻呼消息，组寻呼消息中包含第一指示信息，第一指示信息表征处于空闲态或非激活态的终端组播配置变更的目标候选小区的标识。
示例地，第一指示信息可以采用比特位bitmap进行指示。例如，第一指示信息为{10000}时，目标候选小区为候选小区1，可以理解为候选小区1对 应的组播配置config1发生变更；第一指示信息为{10100}时，目标候选小区包括候选小区1和候选小区3，可以理解为候选小区1对应的组播配置config1和候选小区3对应的组播配置config3发生变更。
步骤4、在确定候选小区更新列表未包括目标候选小区的情况下，终端在空闲态或非激活态，根据第一指示信息表征的目标候选小区的标识删除至少目标候选小区的组播配置。
在该步骤4中，以候选小区更新列表为{01100}，第一指示信息为{10000}为例，终端根据候选小区更新列表{01100}可以确定网络设备期望终端触发状态转换进入连接态，并在连接态更新组播配置变更的候选小区包括候选小区2和候选小区3，根据第一指示信息{10000}确定组播配置发生变更的目标候选小区为候选小区1，因此，候选小区更新列表未包括组播配置发生变更的候选小区1，则终端可以在空闲态或非激活态删除候选小区1对应的组播配置config1。
实施例4
步骤1、网络设备向终端配置至少一个候选小区的组播配置。
需要说明的是，该步骤1中的实现方式与上述实施例1中步骤1的实现方式类似，可参见上述实施例1中步骤1的相关描述，在此，本公开实施例不再进行赘述。
步骤2、网络设备向终端通知候选小区更新列表。
步骤3、网络设备在确定至少一个候选小区的组播配置存在变更的情况下，向终端发送组寻呼消息，组寻呼消息中包含第一指示信息，第一指示信息表征处于空闲态或非激活态的终端组播配置变更的目标候选小区的标识。
需要说明的是，在实施例4中，步骤2和步骤3中的实现方式，分别与上述实施例3中步骤2和步骤3的实现方式类似，可参见上述实施例3中步骤2和步骤3的相关描述，在此，本公开实施例不再进行赘述。
步骤4、在确定候选小区更新列表包括目标候选小区的情况下，终端触发从空闲态或非激活态进入连接态，并在连接态对目标候选小区的组播配置进行更新。
在该步骤4中，以候选小区更新列表为{01100}，第一指示信息为{01000}为例，终端根据候选小区更新列表{01100}可以确定网络设备期望终端触发状 态转换进入连接态，并在连接态更新组播配置变更的候选小区包括候选小区2和候选小区3，根据第一指示信息{01000}确定组播配置发生变更的目标候选小区为候选小区2，因此，候选小区更新列表包括组播配置发生变更的候选小区2，则终端可以触发从空闲态或非激活态进入连接态，并在连接态对候选小区2的组播配置进行更新。
结合上述描述可以看出，上述几个实施例详细地描述了在一种场景中，当候选小区配置包括至少一个候选小区的组播配置时，网络设备在确定终端至少一个候选小区的组播配置发生变更的情况下，向终端发送寻呼消息，寻呼消息包括第一指示信息，第一指示信息用于表征至少一个候选小区的组播配置的变更情况，使得终端可以根据第一指示信息表征的至少一个候选小区的组播配置的变更情况，对至少一个候选小区的组播配置进行处理。下面，将详细描述在另一种场景中，当候选小区配置包括组播配置对应的初始适用的候选小区时，终端如何根据第一指示信息对候选小区配置进行处理的技术方案进行详细描述。
示例地，在另一种场景中，组播配置对应的初始适用的候选小区，该种场景可以理解为：网络设备在确定终端组播配置对应的初始适用的候选小区发生变更的情况下，向终端发送系统信息、组播/广播业务控制信道、或者寻呼消息中的至少一种，其中包括第一指示信息，第一指示信息用于表征组播配置对应的变更后的目标候选小区，使得终端可以在空闲态或非激活态，根据第一指示信息表征的变更后的目标候选小区，将组播配置对应的初始适用的候选小区更新为目标候选小区，这样就可以有效地避免基于变更前的初始适用的候选小区的组播配置接收组播业务的业务数据，从而有效地解决了终端因基于变更前的初始适用的候选小区的组播配置接收组播业务导致的业务数据接收失败的问题。
示例地，终端获取组播配置对应的初始适用的候选小区时，可以通过接收网络设备发送的第二指示信息，第二指示信息用于表征组播配置对应的初始适用的候选小区，从而获取到组播配置对应的初始适用的候选小区。
示例地，初始适用的候选小区为候选小区列表中的候选小区，候选小区列表可以为网络设备为终端预配置的，即网络设备通过第二指示信息表征的初始适用的候选小区，是从候选小区列表中确定出的候选小区。
可以理解的是，在本公开实施例中，网络设备可以先通过候选小区列表为终端配置多个候选小区。然而，该多个候选小区中候选小区可能不全是终端组播配置对应的适用候选区域，因此，网络设备可以进一步通过第二指示信息向终端通知组播配置对应的初始适用的候选小区，使得终端可以准确地获取到组播配置对应的初始适用的候选小区。
示例地，终端接收网络设备发送的第二指示信息和候选小区列表，包括以下可能的实现方式中的一种或者多种：
在一种可能的实现方式中，终端可以接收网络设备发送的无线资源控制RRC重配消息，RRC重配消息包括第二指示信息和候选小区列表，即第二指示信息和候选小区可以一并包括在RRC重配消息中，终端可以通过接收RRC重配消息一并获取到第二指示信息和候选小区列表，可参见下述实施例5。
在另一种可能的实现方式中，终端可以接收网络设备发送的RRC释放消息，RRC释放消息包括第二指示信息和候选小区列表，即第二指示信息和候选小区可以一并包括在RRC释放消息中，终端可以通过接收RRC释放消息一并获取到第二指示信息和候选小区列表，可参见下述实施例6。
在又一种可能的实现方式中，终端可以接收网络设备发送的无线资源控制RRC重配消息，RRC重配消息包括第二指示信息；接收网络设备发送的RRC释放消息，RRC释放消息包括候选小区列表，即第二指示信息包括在RRC重配消息中，候选小区列表包括在RRC释放消息中，终端可以通过接收RRC重配消息和RRC释放消息获取到第二指示信息和候选小区列表，可参见下述实施例7。
在又一种可能的实现方式中，终端可以接收网络设备发送的RRC释放消息，RRC释放消息包括第二指示信息，在终端处于非激活态的情况下，候选小区列表为RRC释放消息中配置无线接入网通知区域RNA的小区列表，即终端处于非激活态的情况下，可以通过接收RRC释放消息获取到第二指示信息和候选小区列表，可参见下述实施例8。
实施例5
步骤1、终端在连接态，网络设备向终端发送RRC重配消息；其中，RRC重配消息中包括候选小区列表和第二指示信息，第二指示信息用于表征组播配置对应的初始适用的候选小区。
示例地，候选小区列表可以包括候选小区1、候选小区2，……，以及候选小区5，可记为{候选小区1、候选小区2，……，候选小区5}。
示例地，第二指示信息可以采用比特位bitmap进行指示。例如，第二指示信息为{11000}时，表征终端组播配置对应的初始适用的候选小区包括候选小区1和候选小区2，第二指示信息为{00110}时，表征终端组播配置对应的初始适用的候选小区包括候选小区3和候选小区4。
步骤2、由于服务小区拥塞等原因，网络设备可以向终端发送RRC释放消息，指示终端进入空闲态或非激活态。
步骤3、网络设备检测组播配置对应的初始适用的候选小区发生变更时，向处于空闲态或非激活态的终端发送下行控制信息(downlink control nformation，DCI)，用于指示系统信息或组播/广播业务控制信道信息存在更变。
示例地，DCI可以为寻呼消息paging DCI，也可以为组播/广播业务控制信道DCI，具体可以根据实际需要进行设置。通常情况下，paging DCI用于指示系统信息存在变更；组播/广播业务控制信道DCI用于指示组播/广播业务控制信道存在变更。
步骤4、处于空闲态或非激活态的终端根据DCI监听系统信息或组播/广播业务控制信道信息；其中，系统信息或组播/广播业务控制信道信息中包括第一指示信息，第一指示信息用于表征组播配置对应的变更后的目标候选小区。
示例地，第一指示信息可以采用比特位bitmap进行指示。例如，第一指示信息为{11000}时，表征终端组播配置对应的变更后的目标候选小区包括候选小区1和候选小区2，第一指示信息为{00110}时，表征组播配置对应的变更后的目标候选小区包括候选小区2和候选小区3。
步骤5、终端在空闲态或非激活态，根据第一指示信息表征的变更后的目标候选小区，将组播配置对应的初始适用的候选小区更新为目标候选小区。
在该步骤5中，以第二指示信息为{11000}，第一指示信息为{00110}为例，终端根据第一指示信息为{11000}可以确定组播配置对应的初始适用的候选小区包括候选小区1和候选小区2，根据第一指示信息为{00110}可以确定组播配置对应的变更后的目标候选小区包括候选小区3和候选小区4，因此， 终端可以在空闲态或非激活态，将组播配置对应的适用候选小区更新为选小区3和候选小区4。
实施例6

实施例7
与上述实施例5不同的是，在实施例7中，网络设备向终端发送RRC重配消息，RRC重配消息中包括候选小区列表，并向终端发送RRC释放消息，RRC释放消息中包括第二指示信息，即候选小区列表和第二指示信息分别通过RRC重配消息和RRC释放消息发送给终端。在分别获取到候选小区列表和第二指示信息后，其他步骤与上述实施例5中的相关步骤类似，可参见上述实施例5中的相关描述，在此，本公开实施例不再进行赘述。
实施例8
与上述实施例5不同的是，在实施例8中，网络设备向终端发送RRC释放消息，RRC释放消息中包括第二指示信息，但未包括候选小区列表，此外，也没有通过RRC重配消息通知终端候选小区列表，在该种情况下，可以将RRC释放消息中配置无线接入网通知区域RNA的小区列表，确定候选小区列表。在分别获取到候选小区列表和第二指示信息后，其他步骤与上述实施例5中的相关步骤类似，可参见上述实施例5中的相关描述，在此，本公开实施例不再进行赘述。可以理解的是，该种情况通常仅针对非激活态的终端。
