Abstract
A communication method implemented by an apparatus includes that a source access network element sends information of a unicast quality of service (QoS) flow of a protocol data unit (PDU) session corresponding to a multicast QoS flow of a multicast broadcast service (MBS) to a target access network element in a handover procedure. The target access network element forwards the information to a session management network element. The session management network element then indicates a user plane network element connected to the target access network element to send data of the MBS to a terminal device through the target access network element and by using a resource of the unicast QoS flow corresponding to the multicast QoS flow of the MBS.
