Title:
NETWORK DEVICE AND WIRELESS COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2018/207775
Kind Code:
A1
Abstract:
A wireless communication method according to the present invention is adapted for dual registration for registering the same UE 50 for both 4G and 5G simultaneously. The wireless communication method comprises: a step in which the UE (50) requests connection with an EPC and transmits to 4G an attach request including a dual registration indication indicating that the UE (50) is dual-registered; and a step in which an MME (100) configuring 4G, on the basis of acquisition of the attach request, notifies an HSS (110) of the dual registration indication indicating that the UE (50) is dual-registered.
