Abstract

Embodiments are disclosed for application function (AF) initiated multicast session join procedures for multicast broadcast services (MBS), where a user equipment (UE) initiates the session leaving procedure. An AF server can receive a request from the UE to fetch content, and determine that the content is provided by the AF server via a multicast session of a MBS. The AF server can transmit another request to a core network (e.g., a next generation core network) to enable the UE to join the multicast session of the MBS. If the UE does not already have a protocol data unit (PDU) session to a Data Network Name/Single Network Slice Selection Assistance Information (DNN/S-NSSAI) providing the multicast session of the MBS, the AF server can invoke application triggering and/or application level redirection to enable the UE to access an AF instance on the DNN/S-NSSAI providing the multicast session of the MBS.
