Abstract: The disclosure relates to a fifth generation (5G) or sixth generation (6G) communication system for supporting a higher data transmission rate. A method performed by an access and mobility management function (AMF) in a wireless communication system is provided. The method includes receiving, from a user equipment (UE), a requested network slice selection assistance information (NSSAI), receiving, from a unified data management (UDM), a subscribed single-NSSAI (S-NSSAI), determining whether an S-NSSAI in the requested NSSAI is either the subscribed S-NSSAI or an alternative S-NSSAI in a UE context, and determining whether to update the UE configuration in case that the S-NSSAI in the requested NSSAI is neither the subscribed S-NSSAI nor the alternative S-NSSAI in the UE context.

Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method performed by a base station in a wireless communication system. A protocol data unit (PDU) session associated with a network slice is identified, based on first information on availability of the network slice. Deactivation of a user plane (UP) resource for the PDU session is performed, in case that a user equipment (UE) moves from a first cell inside a network slice area of service (NS-AoS) to a second cell outside of the NS-AoS, and the UP resource is active for the PDU session. Second information for requesting the deactivation of the UP resource is transmitted to an access and mobility management function (AMF) entity.

Abstract: A method performed by an access and mobility management function (AMF) entity in a wireless communication system is provided. A protocol data unit (PDU) session is established with respect to a terminal via a first network slice. It is determined whether replacement of the first network slice is necessary. In case that replacement is necessary, information on a second network slice is provided to the terminal. A session management (SM) context update message including the information on the second network slice is provided to a session management function (SMF) entity corresponding to the PDU session. An SM context update response message including information on whether a new PDU session is allocable to the second network slice is received from the SMF entity. Based on the SM context update response message, replacement is attempted with the second network slice, replacement is performed with another network slice, or replacement is stopped.
