Abstract:
The present disclosure relates to a communication scheme and system for converging a 5th generation (5G) communication system for supporting a data rate higher than that of a 4th generation (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.

Abstract:
The disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). A method for processing a network slice by a packet data network gateway control plane (PGW-C) in a wireless communication system is provided. The method includes receiving a session create request message from a mobility management entity (MME), identifying whether information indicating that a user equipment (UE) supports a slice quota-based operation is included in the session create request message, and transmitting, to the MME, a session create response message configured based on a result of the identification.
