Abstract: The present invention defines signaling required for separating a network entity (NE) responsible for mobility management (MM) and session management (SM), which are main function of a control plane (CP) in a next generation (NextGen) mobile communication system, and presents a basic procedure for providing mobile communication services including the signaling. Therefore, complexity of core equipment responsible for the CP is reduced in order to implement a network slice function and provide various levels of mobility, and an effect of minimizing a signaling load therebetween can be obtain. In addition, it is possible to efficiently manage the resources of a base station (radio access network (RAN)) and a user plane network entity (UP NF).

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: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). 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 further relates to a method by a session management function (SMF) in a network including a session that is established via a first user plane function (UPF). The method includes determining whether to change the first UPF to a second UPF, and transmitting, to a terminal via an access and mobility function (AMF), a first message including a maintain time of the session established via the first UPF, when the first UPF needs to be changed.

Abstract: The present invention relates to a communication method for merging, with IoT technology, a 5G communication system for supporting a data transmission rate higher than that of a 4G system, and a system therefor. The present invention can be applied to an intelligent service (for example, smart home, smart building, smart city, smart car or connected car, healthcare, digital education, retail, security and safety related services, and the like) on the basis of a 5G communication technology and an IoT-related technology. The present invention provides a method by which a terminal requests authentication from a 3rd party server comprises the steps of: transmitting, to a common control function providing device (common control plane network function serving unit), a service request message including a tenant ID and a slice type provided by an application related to the 3rd party server; receiving a service response message including information on the limited data session from the network slice instance management device when a network slice instance management device (network slice instance unit) selected by the common function providing device generates a limited data session (limited packet data unit session) for authentication between the terminal and the 3rd party server on the basis of the service request message; and transmitting an authentication request message requesting authentication of the terminal through the limited data session to the 3rd party server on the basis of the service response message.
