Original Abstract Submitted

Embodiments of the present disclosure provide methods and apparatuses for multicast/broadcast service (MBS). A method performed by a radio access network node comprises receiving a first request from a core network node in a first network. The first request comprises a multicast/broadcast service (MBS) session identifier (ID) and at least one associated session identifier. The at least one associated session ID is used to make an association for two or more broadcast MBS sessions of two or more networks. The method further comprises when a predefined number of user planes have been established for the two or more MBS sessions, skipping establishing a user plane of a first MBS session towards the first network. The method further comprises when the predefined number of user planes have not been established for the two or more MBS sessions, establishing the user plane of the first MBS session towards the first network.
