Registration management method for terminal accessing 5G network on non-3GPP access
First Claim
1. A method of a base station in a wireless communication system, the method comprising:
- receiving, from an access and mobility management entity executing an access and mobility management function (AMF), a first message requesting location information of a terminal while the terminal is in a radio resource control (RRC) inactive state; and
transmitting, to the access and mobility management entity, a second message including last known location information of the terminal for the base station and a time stamp associated with the last known location information of the terminal based on the first message.

Abstract
A communication technique of fusing a fifth generation (5G) communication for supporting higher data transmission rate beyond a fourth generation (4G) system with an Internet of things (IoT) technology and a system thereof is provided. The technique may be applied to an intelligent service (smart home, smart building, smart city, smart car or connected car, health care, digital education, retail business, security and safety related service, or the like) based on the 5G communication technology and the IoT related technology. A method is provided for effectively managing a registration state for a terminal in a 5G core network such as an access and mobility management function (AMF) in a situation of accessing a 5G network via a non-3rd generation partnership project (3GPP) access.
