Abstract: A disclosure in the present specification provides a method for user equipment initiating a service request procedure. The method includes a step of the UE receiving a paging message. The UE may be registered to both of a 3rd generation partnership project (3GPP) access and a non-3GPP access within the same PLMN. The paging message may include access type information that is used so as to indicate the non-3GPP access. The method may include a step of initiating a UE triggered service request procedure. The UE triggered service request procedure may be initiated by transmitting a service request message including a list of permitted protocol data unit (PDU) sessions. The service request message may include an empty list of the permitted PDU sessions if there is no PDU sessions that can be reactivated in the 3GPP access.

Abstract: A disclosed feature of the present specification provides a method for a source cell determining a handover of a packet data unit (PDU) session. The method may include a step of determining a target cell or target next generation radio access network (NG-RAN) based on a measurement report by a terminal. A handover region list can additionally be considered in the target cell or target NG-RAN determination step. The method may include a step of transmitting a handover request message that does not include context with respect to the PDU session to the target cell or target NG-RAN, based on the handover region list, if it is confirmed that the determined target cell or target NG-RAN cannot serve for the PDU session.
