METHOD FOR TRANSCEIVING SIGNAL IN ASSOCIATION WITH MULTI-HOMING BASED PSA ADDITION IN WIRELESS COMMUNICATION SYSTEM AND APPARATUS THEREFOR

摘要

An embodiment of the present invention relates to a method for transceiving a signal, by a user equipment (UE), in association with multi-homing based PSA addition in a wireless communication system, the method comprising the steps of: establishing a protocol data unit (PDU) session with a first protocol data unit session anchor (PSA); and receiving a new IP address from a session management function (SMF), wherein when the received new IP address is associated with multi-homing based PSA addition, the UE skips performing IMS registration using the new IP address.
