Abstract: A technique comprising: receiving, at a session management function, information by which is identifiable a plurality of multicast service areas for a multicast session managed by the session management function; and directing towards a radio access network node an indication of the plurality of multicast service areas; wherein the plurality of multicast service areas is a subset of the set of multicast service areas for the multicast session.

Abstract: Systems, methods, apparatuses, and computer program products for improved signaling of small data transmission (SDT) are provided. One method may include storing, at a first target network node, a user equipment (UE)-specific uplink (UL) small data transmission (SDT) context for a user equipment (UE) in a non-connected radio resource control (RRC) state that previously had initiated a small data transmission (SDT) procedure without anchor relocation via the first target network node or a second target network node. The method may also include performing radio link control (RLC) processing of the radio link control (RLC) protocol data units (PDUs) received from the user equipment (UE) using the stored user equipment (UE)-specific uplink (UL) small data transmission (SDT) context.

Abstract: Systems, methods, apparatuses, and computer program products for multicast-broadcast service (MBS) deactivation and/or activation are provided. One method may include receiving, at a multicast-broadcast session management entity, a multicast-broadcast service (MBS) session setup message, from at least one management entity, comprising at least one of an identifier of at least one network node requesting setup of the multicast-broadcast service (MBS) session and an identifier of the at least one management entity. The method may also include storing, at the multicast-broadcast management entity, at least one of the identifier of the at least one network node, the identifier of the at least one management entity, or an identifier of a region of the at least one management entity.
