Title:
METHOD FOR TRANSMITTING/RECEIVING IMS VOICE SUPPORT-RELATED SIGNAL BY NG-RAN IN WIRELESS COMMUNICATION SYSTEM, AND APPARATUS THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/059740
Kind Code:
A1
Abstract:
An embodiment of the present invention relates to a method for transmitting/receiving an IP multimedia subsystem (IMS) voice support-related signal by a next generation-radio access network (NG-RAN) in a wireless communication system, the method comprising the steps of: receiving, by the NG-RAN, a request associated with a UE capability for IMS voice from an AMF; checking, by the NG-RAN, whether the UE capability matches network configurations; and transmitting, by the NG-RAN, a response including the result of the check to the AMF, wherein the network configurations include a network configuration for the NG-RAN and a network configuration for a network node which enables IMS voice even when the NG-RAN does not support IMS voice.
