Section: 5.6.3.3 Notification procedure completion
Content: Upon reception of SERVICE REQUEST message, CONTROL PLANE SERVICE REQUEST message or REGISTRATION REQUEST message, the AMF shall stop timer T3565 and proceed service request procedure as specified in subclauses 5.6.3.1 or registration procedure for mobility and periodic registration update as specified in subclauses 5.5.1.3. If no user-plane resources of PDU session(s) need to be re-established, the AMF should notify the SMF that the UE was reachable but did not accept to re-establish the user-plane resources of PDU session(s). When the 5GMM entity in the AMF receives an indication from the lower layer that it has received the NGAP UE context resume request message as specified in 3GPP TS 38.413[ NG-RAN; NG Application Protocol (NGAP) ]  [31], the AMF shall stop timer T3565. Upon reception of NOTIFICATION RESPONSE message over non-3GPP access, the AMF shall stop timer T3565 and should notify the SMF that the UE is unreachable. If the NOTIFICATION RESPONSE message includes the PDU session status information element, then: a) for single access PDU sessions, the AMF shall: 1) perform a local release of all those PDU sessions which are not in 5GSM state PDU SESSION INACTIVE on the AMF side associated with 3GPP access, but are indicated by the UE in the PDU session status information element in the NOTIFICATION RESPONSE message as being in 5GSM state PDU SESSION INACTIVE; and 2) shall request the SMF to perform a local release of all those PDU sessions associated with 3GPP access. If any of those PDU sessions is associated with one or more multicast MBS sessions, the SMF shall consider the UE as removed from the associated multicast MBS sessions; and b) For MA PDU sessions, the AMF shall: 1) for MA PDU sessions having user plane resources established only on the 3GPP access in the AMF side, but are indicated by the UE in the PDU session status information element in the NOTIFICATION RESPONSE message as no user plane resources established on the 3GPP access: i) perform a local release of all those MA PDU sessions; and ii) request the SMF to perform a local release of all those MA PDU sessions. If the MA PDU session is associated with one or more multicast MBS sessions, the SMF shall consider the UE as removed from the associated multicast MBS sessions; and 2) for MA PDU sessions having user plane resources established on both accesses in the AMF side, but are indicated by the UE in the PDU session status information element in the NOTIFICATION RESPONSE message as no user plane resources established on the 3GPP access: i) perform a local release of 3GPP access user plane resources of all those MA PDU sessions; and ii) request the SMF to perform a local release of 3GPP access user plane resources of all those MA PDU sessions. If the MA PDU session is associated with one or more MBS sessions, the SMF shall consider the UE as removed from the associated MBS sessions.
