Method for transmitting and receiving signals in connection with adding MULTI-HOMING based PSA in wireless communication system and apparatus therefor

摘要

An embodiment of the present invention provides a method for transmitting and receiving a signal of a UE (User Equipment) related to adding a multi-homing-based PSA in a wireless communication system, a first protocol data unit session anchor (PSA) and a protocol data unit (PDU) session to establish; Receiving a new IP address from a Session Management Function (SMF), wherein when the received new IP address is related to multi-homing-based PSA addition, the UE skips performing IMS registration using the new IP address This is a signal transmission/reception method related to PSA addition.
