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: The present 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). According to various embodiments of the disclosure, an operating method of a user plane function (UPF) in a wireless communication system and an apparatus therefor are provided. The operating method includes receiving a first parameter for clock synchronization from a base station, and performing the clock synchronization with a neighboring network system using the received first parameter and a second parameter. The first parameter may include information relating to a link delay time between the neighboring network system and a network system comprising the UPF, and a residence time of a terminal, a base station and the UPF of the network system comprising the UPF, and the second parameter may include information relating to a backhaul delay time between the base station and the UPF.

Abstract: A method for selecting an access network in a terminal of a mobile communication system according to one embodiment of the present specification comprises the steps of: if traffic is generated in the terminal, selecting an access network according to the characteristics of the generated traffic and network selection policy information; and transmitting and receiving the generated traffic via the selected access network. According to the embodiment, the present invention adjusts priorities of accesses given to users and applications in a wireless communication system including heterogenerous networks, thereby reducing processes for reselecting an access network of a user terminal, and reducing the cases of unnecessarily accessing a network having a low priority or requiring high costs for a long time. Therefore, the present invention can enhance user convenience and improve communication efficiency.
