Abstract: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The disclosure proposes, when a UE is registered in an AMF which does not support ATSSS (registration procedure), a method by which, an old AMF identifies the registration and releases an MA PDU session and a method by which the UE identifies the registration and releases the MA PDU session in a wireless communication system according to an embodiment.

Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. According to the disclosure, energy use per network slice can be efficiently controlled in a wireless communication system. A method performed by an SMF entity in a wireless communication system includes receiving, from an AMF entity, a first request message for a PDU session establishment including an S-NSSAI; determining whether the S-NSSAI is subject to energy control; and transmitting, to an NF entity, a second request message for an admission control including the S-NSSAI, in case that the S-NSSAI is subject to the energy control.

Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method performed by an AMF in a wireless communication system is provided. The method includes receiving, from a UE, requested NSSAI including a plurality of S-NSSAI, identifying whether each of the plurality of S-NSSAI is available, identifying a number of S-NSSAIs included in an allowed NSSAI; in case that the number of S-NSSAIs in the allowed NSSAI is less than a maximum number of S-NSSAIs for the allowed NSSAI, determining to include alternative S-NSSAI for a first S-NSSAI that is not available, and in case that the number of S-NSSAIs in the allowed NSSAI is at least equal to the maximum number of S-NSSAIs for the allowed NSSAI, determining S-NSSAIs for the allowed NSSAI based on whether the each of the plurality of S-NSSAI is associated with a PDU session.

Abstract: The present disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. The present disclosure provides a method for providing subdivided network slices in a wireless communication system. A method for operating a user equipment (UE) according to an embodiment may comprise transmitting, to an access and mobility management function (AMF), a registration request message including a request slice (requested NSSAI) and a per-cell slice service area support indicator (CSSA support indication) and receiving, from the AMF, a registration accept message including service area information per-allowed slice (slice area per allowed NSSAI) about the UE determined based on the request slice and the per-cell slice service area support indicator.
