    Abstract: The present disclosure relates to a communication technique of fusing a 5G communication system for supporting higher data transmission rate beyond a 4G system with an IoT technology and a system thereof, and provides an intelligent service based on the 5G communication technology and the IoT related technology. A method of an initial access and mobility management function (AMF) in a wireless communication system, includes receiving, from a base station, a registration request message including information on a requested slice; determining whether to reroute the registration request message based on subscription information; transmitting, to a network repository function (NRF), a first message to request information on a target AMF which has required capabilities to serve a terminal; receiving, from the NRF, a second message including information on the target AMF; and rerouting, to the target AMF, the registration request message based on the determination.

    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.

    Abstract: A communication technique that combines a 5G communication system for supporting a data rate that is higher than that of a beyond 4G system with IoT technology, and a system thereof are provided. The technique may be applied to intelligent services on the basis of 5G communication technology and IoT related technology, such as smart home, smart building, smart city, smart car or connected car, health care, digital education, retail, etc. A method of performing access deregistration by a user equipment (UE) and an apparatus therefor are provided. The method includes, when the UE is registered on both 3rd generation partnership project (3GPP) access and non-3GPP access, transmitting, to an access and mobility management function (AMF), a deregistration request message to deregister the non-3GPP access over the 3GPP access, and receiving, from the AMF, a deregistration accept message corresponding to the deregistration request message over the 3GPP access.
