GATEWAY AND NETWORK ALLOCATION METHOD OF GATEWAY MOBILE MANAGEMENT ENTITY AND NETWORK ALLOCATION METHOD OF MOBILE MANAGEMENT ENTITY AND TERMINAL AND NETWORK CONNECTING METHOD OF TERMINAL IN WIRELESS COMMUNICATION SYSTEM

摘要

The present invention relates to a network allocation method of a gateway in a wireless communication system where a first communication network and a second communication network are able to operate, which comprises the steps of: while a terminal is connected to the first communication network, receiving a session generation requesting message from a second mobility management entity related to a second base station operating the second communication network; using first connection information, which is generated in advance, to be connected to the first communication network and allocating second connection information for generating a bearer from the gateway to the second base station; and on the basis of the session generation requesting message, transmitting a session generation responding message comprising the allocated second connection information to the second mobility management entity. According to one embodiment of the present invention, since a 4G communication network and a 5G communication network are operated in a standalone way, dependency on a specific radio access technology (RAT) can be removed.
