1. A method performed by a user equipment (UE), the method comprising:
transmitting a request to join a particular multicast-broadcast services (MBS) session, the request comprising an MBS session identifier (ID) identifying the particular MBS session,
in response to the request, receiving a first message comprising a group ID allocated for the particular MBS session, the group ID being different than the MBS session ID and comprising a group 5G-S-Temporary Mobile Subscriber Identity (5G-S-TMSI) assignable to a plurality of UEs that join the particular MBS session via unicast; and
while the UE is camping on a radio access network (RAN) node that does not support MBS and is in a radio resource control (RRC) state other than RRC_CONNECTED, receiving from the RAN node a paging message; and
determining whether the paging message comprises the group ID.
