establishing, by a gNodeB, a MBS session with a user equipment (UE) for reception of a high priority MBS;

receiving, by the gNodeB, a service migration request from the UE, wherein the service migration request comprises a service migration identifier information comprising a priority service identifier of the high priority MBS;

determining, by the gNodeB, at least one of change a bandwidth part (BWP) configuration for the UE, a bearer type change (BTC) for reception of the MBS at the UE, and deactivating lower priority MBS at the UE in response to receiving the service migration request; and

transmitting, by the gNodeB, a service migration response to the UE for service migration,

wherein the service migration response comprises at least one of: an updated BWP configuration in response to determining by the gNodeB to change the BWP configuration for the UE, an updated bearer configuration in response to determining by the gNodeB to the BTC for the UE, and at least one of a Group Radio Network Temporary Identifier (G-RNTI) or a Group-Configured Scheduling-Radio Network Identifier (G-CS-RNTI) of lower priority MBS, a Logical Channel ID (LCID) information of lower priority MBS, an identifier of the MBS session and a Temporary Mobile Group Identifier (TMGI) for service deactivation in response to determining by the gNodeB to deactivate lower priority MBS at the UE.
