本申请主张在2021年09月30日在中国提交的中国专利申请号202111161022.2的优先权，其全部内容通过引用包含于此。
技术领域
本申请属于通信技术领域，具体涉及一种多播会话处理方法、装置、用户设备及存储介质。
背景技术
多播广播业务(Multicast Broadcast Service，MBS)是一种无线通信系统的重要功能，MBS业务/MBS会话是在移动网络中提供一个数据源向多个用户设备(User Equipment，UE)发送数据的点到多点业务，实现网络资源共享，提高网络资源的利用率。UE和网络侧设备可以对MBS业务的相关信息进行交互，以实现MBS业务的各种功能(例如MBS业务去激活)。然而，对于MBS业务去激活，由于网络侧设备没有明确的向UE指示MBS业务去激活，使得UE一直以为MBS业务还在激活状态，因此导致UE在后续过程中不会去监听多播业务的激活通知。
