Abstract: In 5GS, Single-Network Slice Selection Assistance Information (S-NSSAI) based backoff (BO) timers (T3585) can be applied to either 3GPP access or non-3GPP access or both access based on a 5GSM congestion re-attempt indicator. When UE receives a 5GSM message over a specific access, UE needs to handle a current running timer. In one novel aspect, it is proposed that the UE stops the running timer applied for the same access which the message is received, and also stops the running timer applied for both access types. In another novel aspect, it is proposed that the UE stops the running timer applied for the access different from the access which the message is received when the UE starts a new timer applied for both access types.

Abstract: A method for handling a PDU session status IE for MBS when the PDU session status IE indicates that the PDU session is inactive is provided. A UE receives a service accept or a service reject message from the network, which comprises a PDU session status IE indicating that a PDU session is inactive. Accordingly, the UE locally releases the PDU session if the PDU session is active, and determines if the PDU session is associated with one or more MBS sessions. If so, the UE locally leaves the associated MBS sessions. The PDU session can be a single access PDU session or a multiple access PDU session.
