为了便于理解，下面先介绍本申请涉及的几个名词概念。
1)MBS
MBS也称为多媒体广播多播业务(Multimedia Broadcast and Multicast Service，MBMS)。
在5G NR(New RAT(Radio Access Technology)，新无线接入技术)系统中，MBS业务可以通过PDCCH(Physical Downlink Control Channel，物理下行控制信道)调度的PDSCH(Physical Downlink Shared Channel，物理下行共享信道)信道发送。该调度MBS业务的PDCCH通过MBS业务特定的调度标识进行指示(如，G-RNTI(GroupRadio Network Temporary Identity)，MBS无线网络临时标识)。
MBS业务可以通过以下“MBS业务标识”标记：
临时移动组标识(Temporary Mobile Group Identity，TMGI)；
MBS会话标识(MBS Session ID)；
以及，MBS业务流标识(MBS QoS flow ID)。
其中，MBS业务可以通过特定的MBS无线承载(MBS Radio Bearer，MRB)进行发送。请参考图1，其是根据一示例性实施例示出的协议栈结构示意图。如图1所示，承载MBS业务的无线承载的协议栈结构可以包括普通MBS承载和分离MBS承载中的任意一种：
普通MBS承载(如图1中的(a)部分所示)：1个包数据汇聚协议(Packet Data Convergence Protocol，PDCP)实体关联1个无线链路控制(Radio Link Control，RLC)实体，该RLC实体的数据通过组G-RNTI(GroupRadio Network Temporary Identity，无线网络临时标识)PDCCH(Physical Downlink Control Channel，物理下行控制信道)调度发送。
分离MBS承载(如图1中的(b)部分所示)：1个PDCP关联2个RLC实 体，1个RLC实体的数据通过G-RNTIPDCCH调度发送，1个RLC实体的数据通过C-RNTI(Cell-RadioNetworkTemporaryIdentifier，小区无线网络临时标识)PDCCH调度发送。
其中，MBS业务的发送模式包括以下两种：
发送模式1(多播发送)：终端(也称为用户设备(User Equipment，UE))进入RRC连接态(CONNECTED态)接收MBS业务的发送配置信息，从而接收MBS业务。网络侧通过UE专属信令将MBS业务的接收配置信息发送给UE。MRB采用图1中的普通MBS承载。
发送模式2(广播发送)：UE可以在IDLE或INACTIVE或CONNECTED状态接收MBS业务的发送配置信息，并接收MBS业务。网络侧通过系统信息(如，SIB(System Information Block，系统信息块))和MBS控制信道信息(如，MCCH(MBS Control Channel，MBS控制信道))将MBS业务的接收配置信息发送给UE。MRB采用图1中的普通MBS承载或分离MBS承载。
2)RRC状态
UE的接入层(Access Stratum，AS)的连接状态包括以下3种：
空闲态(RRC_IDLE):采用基于UE的小区选择的移动性。通过非连续接收(Discontinuous Reception，DRX)方式接收核心网的寻呼消息。
非激活态(RRC_INACTIVE)：采用基于UE的小区选择的移动性。通过DRX方式接收接入网的寻呼消息。UE挂起用于业务接收的数据无线承载(Data Radio Bearer，DRB)，并保留接入层的DRB配置信息。UE接入层的配置信息保存在锚点(Anchor)gNB。
连接态(RRC_CONNECTED)：采用基于网络配置的小区切换的移动性。gNB和UE建立并保存UE的接入层上下文，并通过DRB收发单播业务。
3)双连接(Dual Connectivity，DC)
UE可以被配置2个小区组:
主小区组(Master Cell Group，MCG)：包括1个主小区(Primary Cell，PCell)。可选的配置1个或多个辅小区(Secondary Cell，SCell)。
辅小区组(Secondary Cell Group，SCG)：包括1个主辅小区(Primary Secondary Cell，PSCell)。可选的配置1个或多个SCell。
其中，PCell和PSCell可以统称为特殊小区(Special Cell，SpCell)。
对于采用多播方式(即上述发送模式1)发送的MBS业务，UE进入RRC连接态后加入多播组，网络侧可以将接收该MBS业务的配置信息，比如，G-RNTI，MBS会话标识，MRB承载配置(包括PDCP/RLC/逻辑信道的配置信息，接收MBS业务的DRX配置(如，业务监听周期/监听起始位置/监听时长))发送给UE。然而，该方案需要一直将UE保持在RRC连接态，这会导致更多的UE耗电(比如连接态的测量和控制信道监听)。
本申请各个实施例提供一种MBS的传输方案，使得UE能够在INACTIVE/IDLE状态接收多播MBS业务，从而在多播MBS传输场景下，降低终端的功耗，提高终端的续航能力。

图4是根据一示例性实施例示出的一种广播多播业务传输方法的流程图，该广播多播业务传输方法可以由网络侧设备执行，比如，该网络侧设备可以是图2所示的实施环境中的基站220或者网络管理设备230。如图4所示，该方法可以包括以下步骤。
步骤401，向用户设备发送配置指示信息；该配置指示信息用于指示广播多播业务MBS接收配置信息，以便该用户设备在无线资源控制RRC空闲态或者RRC非激活态下，基于该MBS接收配置信息接收通过多播方式发送的MBS数据。
在一种可能的实现方式中，向用户设备发送配置指示信息，包括：
响应于该用户设备处于RRC连接态下，向该用户设备发送连接释放消息；该连接释放消息中携带有该配置指示信息。
在一种可能的实现方式中，该配置指示信息中包含该MBS接收配置信息；

综上所述，本申请实施例所示的方案，网络侧设备向用户设备指示MBS接 收配置信息，以便用户设备在RRC空闲态或者RRC非激活态下接收通过多播方式发送的MBS数据，使得UE能够在INACTIVE/IDLE状态接收多播MBS业务，从而在多播MBS传输场景下，降低终端的功耗，提高终端的续航能力。
图5是根据一示例性实施例示出的一种广播多播业务传输方法的流程图，该广播多播业务传输方法可以由用户设备和网络侧设备交互执行，比如，该通信设备可以是图2所示的实施环境中的用户设备210，网络侧设备可以是图2所示的实施环境中的基站220或者网络管理设备230。如图5所示，该方法可以包括以下步骤。
在步骤501中，网络侧设备向用户设备发送配置指示信息，用户设备接收该配置指示信息。
其中，该配置指示信息用于指示广播多播业务MBS接收配置信息。
在一种可能的实现方式中，网络侧设备向用户设备发送配置指示信息，包括：
响应于该用户设备处于RRC连接态下，向该用户设备发送连接释放消息；该连接释放消息中携带有该配置指示信息。
相应的，在RRC连接态下，用户设备接收来自该网络侧设备的连接释放消，并获取该连接释放消息中携带的该配置指示信息。
在本申请实施例中，网络侧设备可以给UE提供MBS接收配置信息。其中，该MBS接收配置信息用于IDLE态或INACTIVE态下的UE的MBS业务数据的接收。
比如，网络侧设备在RRCRelease消息中，指示UE进入INACTIVE状态(例如，通过“suspendConfig”信令来指示)。同时，网络侧设备指示用于INACTIVE态的UE的MBS业务数据接收的MBS接收配置信息。例如，该MBS接收配置信息可以是“mbsConfig”信息。
在一种可能的实现方式中，该配置指示信息中包含该MBS接收配置信息。
在一个示例性的方案中，上述MBS接收配置信息可以是通过配置指示信息进行显式配置的，也就是说，上述配置指示信息中包括MBS接收配置信息。
在一种可能的实现方式中，该配置指示信息指示将RRC连接态下使用的该MBS接收配置信息，作为在RRC空闲态或者RRC非激活态下使用的该MBS 接收配置信息。
在一个示例性的方案中，上述MBS接收配置信息可以是通过配置指示信息隐式配置，也就是说，该配置指示信息指示UE在进入INACTIVEA态后，保留之前CONNECTED态接收并使用的MBS接收配置信息，作为RRC空闲态或者RRC非激活态下使用的MBS接收配置信息。
例如，如果上述MBS接收配置信息之前在UE处于CONNECTED态是，已经由网络侧设备已经提供给了UE，则网络侧设备在将UE配置进入IDLE态/INACTIVE态的时候，可以指示之前在CONNECTED态提供的MBS接收配置信息是否保留用于IDLE/INACTIVE状态。
比如，网络侧设备通过RRCReconfig消息提供了“mbsConfig”，则网络侧设备在RRCRelease消息中可以指示是否该“mbsConfig”用于IDLE/INACTIVE状态。例如，RRCRelease消息中1bit取值“1”表示RRCReconfig消息提供的“mbsConfig”用于IDLE/INACTIVE状态。
在一种可能的实现方式中，该MBS接收配置信息包括：
MBS业务标识；
MBS业务调度标识；比如该MBS业务调度标识可以表示为G-RNTI-1；
以及，MBS承载配置。
其中，该MBS承载配置(即，MRB配置)包括以下至少一项：
PDCP配置、RLC配置、以及逻辑信道配置。
在一种可能的实现方式中，该MBS接收配置信息还包括：
非连续接收配置以及用于MBS业务接收的安全配置中的至少一种。
可选的，MBS接收配置信息还可以包括非连续接收配置，例如发送周期、起始时间、以及每个周期的持续时长等。
此外，MBS接收配置信息还可以包括MBS业务接收的安全配置，例如安全密钥，和/或，安全算法。不同于单播业务(如，DRB)接收的安全配置，在多播MBS业务中，网络侧设备可以为UE的MBS业务提供MBS业务接收的安全配置。
在步骤502中，用户设备确定该MBS接收配置信息适用的区域信息。
在一种可能的实现方式中，该区域信息由该网络侧设备指示。
也就是说，在本申请实施例中，网络侧设备可以向该用户设备指示该MBS 接收配置信息适用的区域信息。
例如，网络侧设备可以通过上述配置指示信息直接携带或者隐式的指示该MBS接收配置信息适用的区域信息。
或者，网络侧设备也可以通过配置指示信息之外的其它指示信息来直接携带或者隐式的指示该MBS接收配置信息适用的区域信息。
在另一种可能的实现方式中，上述区域信息由协议预定义。
在另一个示例性的方案中，上述区域信息可以由通信协议预先定义。例如，协议中预先定义好该区域信息，或者，该协议中预先定义好该区域信息的确定方式，由用户设备根据该确定方式来确定该区域信息。
在一种可能的实现方式中，该区域信息包括以下信息中的至少一种：
小区或小区列表；例如，RRCRelease消息指定“mbsConfig”适用于小区1和小区2；
小区类型；其中，该小区类型包括以下任意一种：连接态的服务小区(例如，协议约定RRCRelease消息配置的“mbsConfig”对于IDLE/INACTIVE态UE，适用于其在连接态下被配置的所有服务小区)、PCell(例如，协议约定RRCRelease消息配置的“mbsConfig”对于IDLE/INACTIVE态UE，适用于其在连接态被配置的PCell)、MCG小区(例如，协议约定RRCRelease消息配置的“mbsConfig”对于IDLE/INACTIVE态UE，适用于其在连接态被配置的MCG的小区)、连接态配置的MBS接收配置信息适用的小区(例如，网络侧设备通过RRCReconfig消息提供了“mbsConfig”，其中该“mbsConfig”适用于连接态的小区1；则网络侧设备在RRCRelease消息中可以指示该“mbsConfig”用于IDLE/INACTIVE状态，也就是说，对于IDLE/INACTIVE态UE，该“mbsConfig”适用于小区1)；
MBS区域标识；例如，MBS-Area-1；
接入网寻呼区域标识；例如，RNA-1(RAN-based Notification Area，接入网寻呼区域)；
跟踪区域(Track Area，TA)的域标识。
在一种可能的实现方式中，该用户设备还可以将该区域信息对应的频点或小区，设置为该用户设备进行小区选择或重选的高优先级频点或小区。
在本申请实施例中，UE将MBS接收配置信息适用的区域对应的频点或小 区，设置为小区选择或重选的高优先级频点或小区。
例如，网络侧设备配置的MBS接收配置信息适用的区域为频点1或小区1，则UE在小区选择/重选过程中，将频点1或小区1设置为最高优先级，以优先接入MBS业务对应的频点或者小区，保证MBS传输的性能。
在一种可能的实现方式中，响应于该用户设备移出该区域信息指示的区域，或者，该用户设备接收MBS数据的兴趣发生变化，或者，该用户设备接收到来自网络侧的接收配置变更消息，取消将该区域信息对应的频点或小区，作为该用户设备进行小区选择或重选的高优先级频点或小区的设置。
在一个示例性的方案中，如果UE移动出MBS接收配置信息适用的区域，则UE触发MBS区域更新行为。其中，该MBS区域更新行为包括，如果UE将MBS接收配置信息适用的区域对应的的频点或小区，设置为小区选择或重选的高优先级频点或小区，则UE去除该高优先级设置。
比如，网络侧设备配置的MBS业务接收配置信息“适用的区域”为频点-1(或小区-1)，则UE在小区重选过程中将频点1(或小区1)设置为最高优先级。此时，UE从频点1(或小区1)重选到频点2(或小区2)，则UE去除频点1(或小区1)的最高优先级设置，而采用系统信息中提供频点1(或小区1)的优先级。
在一个示例性的方案中，如果UE接收MBS业务的兴趣发生了变更(例如，用户在看电视，用户可以根据自己的兴趣在不同的电视频道间转换，也即对MBS业务的兴趣发生了变更)，则UE触发“MBS兴趣变更行为”。其中，该“MBS兴趣变更行为”类似于上述的“MBS区域更新行为”。比如，该MBS兴趣变更行为包括，如果UE将MBS接收配置信息适用的区域对应的的频点或小区，设置为小区选择或重选的高优先级频点或小区，则UE去除该高优先级设置。
其中，UE对某MBS业务感兴趣，表示UE期望接收该MBS业务数据。而，UE对某MBS业务不感兴趣，表示UE不再接收该MBS业务数据。
其中，该MBS兴趣变更包括以下任意一种：
1)UE对MBS接收配置信息中配置的部分或全部MBS业务不再感兴趣；
2)UE希望接收新的MBS业务；例如，该新的MBS业务不包括在MBS接收配置信息中。
在一种可能的实现方式中，该接收配置变更消息是网络侧通过RRC消息或 者物理信道信息指示的。也就是说，网络侧设备通过RRC消息或者物理信道信息，向该用户设备指示该MBS接收配置信息适用的区域信息。
网络侧对于该MBS接收配置信息和/或MBS接收配置信息适用的区域信息需要更新的时候，网络侧设备通知UE进行MBS配置更新。比如，通过paging信指示UE进行MBS配置更新。
其中，该MBS配置更新的指示信息的类型包括以下任意一种：
1)通过RRC消息指示；比如，在Paging的RRC消息中指示“MBS配置更新”；
2)通过物理信道信息指示；比如，通过G-N-RNTI PDCCH指示“MBS配置更新”；或者，通过paging的PDCCH中的short message比特指示“MBS配置更新”。
响应于UE采用MBS接收配置信息进行MBS数据接收，UE可以监听上述“MBS配置更新”的指示信息。
在步骤503中，用户设备在无线资源控制RRC空闲态或者RRC非激活态下，基于该MBS接收配置信息，以及该区域信息接收通过多播方式发送的MBS数据。
在一种可能的实现方式中，用户设备还可以对MAC实体进行指定处理；
该指定处理包括以下处理方式中的至少一种：
清空除了用于多播的下行HARQ进程以外的其他HARQ进程的缓存数据；
对于除了用于多播的下行HARQ进程以外的其他HARQ进程，将该其他HARQ进程的下一个接收数据设置为新传数据。
根据上述的MBS接收配置信息，UE可以对其对应的协议实体进行配置。其中，该“UE对其对应的协议实体进行配置”的行为可以包括对MAC实体进行处理。
其中，该“对MAC实体进行处理”进行处理的行为包括将下行HARQ(Hybrid Automatic Repeat Request，混合自动重传请求)实体区分单播和多播进行处理。进一步的，该处理行为包括以下至少一项：
1)将除了用于多播的下行HARQ进程以外的其他HARQ进程的缓存数据清空。
比如，UE有HARQ进程1-8。其中，通过多播调度(例如，G-RNTI动态 调度或MBS半持续调度)，HARQ进程1-4中有多播业务的缓存数据，和/或，被配置预留用于多播业务的接收；则UE清除HARQ进程5-8中的缓存数据。
2)对于除了用于多播的下行HARQ进程以外的其他HARQ进程，该HARQ进程的下一个接收数据为新传数据。
比如，UE有HARQ进程1-8。其中，通过多播调度(例如，G-RNTI动态调度或MBS半持续调度)，HARQ进程1-4中有多播业务的缓存数据，和/或，被配置预留用于多播业务的接收；则对于HARQ进程5-8，下一次接受到的TB(Transport Block，传输块)为首次接收的TB。
在一种可能的实现方式中，响应于该用户设备对应的MBS承载为分离MBS承载，用户设备还将该分离MBS承载的单播路径挂起。
在一种可能的实现方式中，将该分离MBS承载的单播路径挂起的行为包括以下行为中的至少一种：
将该分离MBS承载的单播路径的RLC实体挂起；
以及，停止对该MBS承载的单播路径的调度信息的接收。
如果UE接收的MBS数据对应的MRB的承载类型为“分离MBS承载”，则UE将分离承载的单播路径挂起或删除(比如，删除单播路径的RLC实体)。其中，该“将分离承载的单播路径挂起”的行为包括以下至少一项：
1)将分离承载的单播路径的RLC实体挂起；比如，停止该RLC实体的上行数据发送和/或下行数据接收；
2)停止该单播路径的调度信息的接收；比如，停止C-RNTI PDCCH的监听。
在步骤504中，响应于该用户设备移出该区域信息指示的区域，或者，该用户设备接收MBS数据的兴趣发生变化，或者，该用户设备接收到来自网络侧的接收配置变更消息，用户设备触发连接恢复过程。
其中，上述“MBS区域更新行为”还包括：触发连接恢复过程。比如，网络配置的MBS接收配置信息用的区域为小区1，UE重选到小区2，则INACTIVE态下的UE触发连接恢复过程。
在一个示例性的方案中，响应于UE的MBS兴趣发生变化，也可以触发连接恢复过程。
在一个示例性的方案中，响应于UE接收到“MBS配置更新”指示信息，UE也可以触发连接恢复过程。
在一种可能的实现方式中，响应于该连接恢复过程由该用户设备移出该区域信息指示的区域触发，向该网络侧设备指示连接恢复原因为MBS接收区域更新，或者MBS接收区域变更；
在本申请实施例中，如果UE触发连接恢复过程，则UE向网络侧指示该“连接恢复原因”为“MBS接收区域更新或变更”。比如，resumeCause设置为“mbsAreaUpdate”。
在一种可能的实现方式中，响应于该连接恢复过程由该用户设备接收MBS数据的兴趣发生变化触发，向该网络侧设备指示连接恢复原因为MBS兴趣变更，或者上行信令发送；
在本申请实施例中，如果UE触发连接恢复过程，则UE向网络侧指示该“连接恢复原因”为以下任意一种：
MBS兴趣更新，比如，mbsInterestUpdate；
以及，上行信令发送，比如，mo-Signalling。
在一种可能的实现方式中，响应于该连接恢复过程由该接收配置变更消息触发，向该网络侧设备指示连接恢复原因为以下至少之一：MBS配置更新、MBS接收区域更新以及MBS接收区域变更。
在本申请实施例中，如果UE触发连接恢复过程，则UE向网络侧指示该“连接恢复原因”为“MBS配置更新”(比如，mbsConfigUpdate)，或者，“MBS接收区域更新或变更”(比如，mbsAreaUpdate)。
其中，UE向网络侧设备上报“连接恢复原因”的目的，可以是让网络侧设备可以根据“连接恢复原因”判断是否让UE恢复EEC连接。比如，网络侧设备当前是拥塞状态，因此只能优先让一些比较紧急业务的恢复RRC连接，而该“连接恢复原因”是让网络侧设备可以确定UE进行连接恢复的业务需求，从而让网络可以判断出是否需要通过接入控制优先恢复一些UE的RRC连接。
在一种可能的实现方式中，响应于该用户设备触发了连接恢复过程，且接收到来自网络侧的恢复RRC连接的指示(如，UE接收到RRCResume消息)，用户设备恢复该MBS承载的单播路径。
在本申请实施例中，如果UE在上述步骤中将分离承载的单播路径挂起，则在网络允许恢复RRC连接时，UE将分离承载的单播路径恢复。其中，该“将分离承载的单播路径恢复”的行为包括以下至少一项：
将分离承载的单播路径的RLC实体恢复；比如，恢复该RLC实体的上行数据发送和/或下行数据接收；
以及，恢复该单播路径的调度信息的接收；比如，恢复C-RNTI PDCCH的监听。
综上所述，本申请实施例所示的方案，用户设备通过获取网络侧设备指示的MBS接收配置信息，在RRC空闲态或者RRC非激活态下接收通过多播方式发送的MBS数据，使得UE能够在INACTIVE/IDLE状态接收多播MBS业务，从而在多播MBS传输场景下，降低终端的功耗，提高终端的续航能力。
