-RAN发起寻呼,寻呼消息(Paging消息)中携带组播下行数据所属组的组信息、或者相关的MBS会话信息,例如组标识信息;
-如果系统信息块(SIB,System Information Block)中携带通知机制信息,则可以在Paging消息中携带MBS业务更新的指示信息,例如特定SIB更新指示信息;
-RAN在所有PO上发送寻呼消息;终端根据现有PO计算方式接收寻呼消息,如果寻呼消息中 或者所述SIB中携带感兴趣组的信息,则进入连接态,发起服务请求(service request)激活所述组的MBS session,接收下行数据。
此实施例减少了对无关终端的影响,对RAN侧没有组信息存储要求。
如图3为本实施例的具体步骤示意图,包括以下步骤:
1.MBS数据到达用户面功能(UPF,User Plane Function);
2.UPF将MBS数据在组数据的N3通道上发送给RAN节点;

或者,
-RAN根据组特定DRX周期(group-specific DRX)和组标识(group ID)计算组特定寻呼时机(group-specific PO),在此PO上发送寻呼消息,其中携带组播指示信息;
