摘要： The present disclosure relates to a 5G or pre-5G communication system for supporting a data transmission rate higher than that of a 4G communication system such as LTE. According to one embodiment of the present invention, a method in a roaming environment supporting a network slice is provided. The method comprises the steps of: receiving, from a terminal, a first packet data unit (PDU) session request message including slice assistance information indicating the properties of a service the terminal intends to use; transmitting, to a network function (NF) repository function, a first discovery request message including a home public land mobile network (PLMN) ID of the terminal and the slice assistance information; and receiving, from the NF repository function, a first discovery response message including a session management network function (SM NF) address of the home PLMN. The SM NF is selected on the basis of the slice assistance information.

摘要： Provided are a method and apparatus for supporting migration of mobile edge computing in a wireless communication system. A method, performed by a Session Management Function (SMF), of controlling a path between an Application function (AF) and a user equipment in a wireless communication system includes: receiving, from the AF, an AF request message including information indicating whether User Plane Function (UPF) modification is allowed; determining whether a modification of a UPF in the path between the AF and the user equipment is required; transmitting a notification including information associated with the modification of a UPF to the AF, based on a result of the determining whether the modification of the UPF is required; determining whether to wait for reception of a response message from the AF for a certain period of time, based on the information indicating whether UPF modification is allowed; and controlling a modification of the path between the AF and the user equipment, the path including the UPF, based on a result of the determining whether to wait.

摘要： A method of performing communication, by a network exposure function (NEF), in a wireless communication system is provided. The method includes receiving a connection establishment request from a session management function (SMF), based on a protocol data unit (PDU) session establishment procedure performed between the SMF and a user equipment (UE), performing a non-internet protocol (IP) data delivery (NIDD) configuration procedure according to NIDD configuration information included in the connection establishment request, based on whether the NIDD configuration procedure is previously performed on the UE between the NEF and an application function (AF), establishing connection between the SMF and the NEF, and transmitting a connection establishment response to the SMF.
