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 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.
