Abstract

The present invention relates to a method for selecting a serving AMF of a network node in a wireless communication, and the method may comprise the steps of: receiving a registration request messageof a terminal, wherein the registration request message includes network slice selection assistance information for a slice requested by the terminal and priority information of the NSSAI; determiningwhether the NSSAI is valid for the terminal; when the NSSAI is valid for the terminal, retrieving a first AMF which can support the NSSAI, on the basis of the priority information; and when the firstAMF is retrieved, selecting the first AMF as the serving AMF for serving the terminal, and transmitting the registration request message to the first AMF.

Description

technical field [0001] The present invention relates to a wireless communication system, and more particularly, to a method for efficiently selecting a network node capable of supporting a slice / service requested by a user equipment (UE) and an apparatus performing the method. Background technique [0002] Mobile communication systems have been developed to provide voice services while ensuring user activity. However, the service coverage of the mobile communication system extends even to the data service as well as the voice service, and at present, a more advanced mobile communication system is required due to resource shortage caused by explosive growth of services and users' demands for high-speed services. [0003] The requirements of the next-generation mobile communication system may need to support the accommodation of explosive data traffic, a significant increase in the transmission rate of each user, the accommodation of a significantly increased number of connect...
