Abstract: A communication method and system converges a 5G communication system for supporting higher data rates beyond a 4G system with an IoT technology. The system and method 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. Embodiments provide a scheme for efficiently operating an UP connection of a session in case where a terminal has a plurality of sessions in a mobile communication system, such as a 5G system, having a network structure in which an AMF for mobility management and an SMF for session management are separated from each other. A terminal (UE) can optimize a non-access stratum (NAS) signaling message, and can perform data transmission/reception with low latency.

Abstract: The present disclosure relates to a 5G or 6G communication system for supporting higher data transmission rates, and pertains to an operation method of a user equipment (UE). The operation method comprises the steps of transmitting a registration request message including a traffic category support indication to an access and mobility management function (AMF) via an access node, receiving, from the AMF via the access node, a UE configuration update message including UE route selection policy (URSP) rules determined on the basis of the traffic category support indication and first traffic category mapping information, and determining a protocol data unit (PDU) session for application traffic on the basis of the URSP rules and pre-stored second traffic category mapping information.

Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. According to an embodiment of the disclosure, a method performed by a user equipment (UE) comprises transmitting, to a UDM (unified data management), a first message for credentials for the UE, the credentials for the UE including at least one of name information, a mobile phone number, and a date of birth. The method comprises receiving, from the UDM, a second message indicating authentication success, wherein the second message includes a user ID corresponding to the credentials for the UE. The method comprises receiving, from an AMF (access and mobility management function), a third message to trigger local authentication of the UE. The method comprises performing the local authentication for the UE based on the second message and the third message.
