Abstract:
The present disclosure relates to a communication method and system for converging a 5G communication system for supporting higher data rates beyond a 4G system with an IoT technology. 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 present disclosure provides 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. Through the present disclosure, a terminal (UE) can optimize a non-access stratum (NAS) signaling message, and can perform data transmission/reception with low latency.

Claim (Index 6):
A method by an access and mobility management function (AMF) entity for managing a protocol data unit (PDU) session in a wireless communication system, comprising:\n receiving a first message, requesting a location change notification for a terminal in an idle state, from a session management function (SMF) entity; and transmitting a second message, including information on a changed location of the terminal, to the SMF entity based on the first message if the location change of the terminal is detected, wherein the second message is used to determine whether to maintain at least one of a plurality of user plane functions (UPFs) included in the PDU session for the terminal by the SMF entity.
