    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.

    Abstract: A Mobility Management Entity (MME), a local server, an MME-local server interface, and a data transmission method are provided. The communication method of an MME supporting inter-gateway handover of a terminal includes acquiring, when a handover from a source gateway to a target gateway is detected during an ongoing data communication of the terminal, information on a session between the terminal and a server and transmitting, when the server is a local server present in a mobile communication core network, a tunnel setup command to the local server through an interface established with the local server, the tunnel setup command instructing to establish a tunnel between the local server and the target gateway for data communication from the local server to the target gateway.

    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.
