Abstract
A method for handling the joining and leaving an MBS session via a PDU session establishment or modification procedure is provided. Upon receipt of a back-off timer in the Received MBS Container IE (with the operation/decision 'MBS join is rejected' or “Remove UE from the MBS session”), the UE shall associate the MBS back-off timer with the MBS session ID (e.g., TMGI). If the timer value is neither zero nor deactivated, the UE should not request to join the MBS session with the same MBS session ID before the timer expiry. If the timer value is deactivated, the UE should not request to join the MBS session with the same MBS session ID until the UE is switched off, the USIM is removed, an entry in the “list of subscriber data” for the current SNPN is updated, or an event/notification is triggered by the network.
