Abstract: The present invention relates to a communication system and method for merging, with IoT technology, a 5G communication system for supporting a data transmission rate higher than that of a 4G system. The present invention provides a system and method by which a user equipment (UE) transmits, to an access and mobility management function (AMF), a first message including information related to a network slice in a first authentication, and receives, from the AMF, a third message including a result of a second authentication, wherein whether to require the second authentication is determined by the AMF based on the information and subscription information, and wherein the second authentication between the UE and a server is triggered based on the determination.

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.
