Abstract
The present disclosure relates to a communication scheme and system for converging a 5generation (5G) communication system for supporting a data rate higher than that of a 4generation (4G) system with an Internet of things (IoT) technology. The present disclosure is applicable to intelligent services (e.g., smart homes, smart buildings, smart cities, smart cars, connected cars, health care, digital education, retails, and security and safety-related services) based on the 5G communication technology and the IoT-related technology. The present disclosure provides a method performed by a session management function (SMF) entity in a communication system, which includes identifying whether a terminal is moved out of a service area corresponding to a protocol data unit (PDU) session; and in case that the terminal is moved out of the service area corresponding to the PDU session, transmitting, to a user plane function (UPF) entity a first request message to remove information on a connection between a base station and the UPF entity, the connection being associated with the PDU session.
