WIPO Patent Application WO/2018/143713

A1

The present disclosure relates to a method and an apparatus for supporting mobility of a terminal. A method for performing an area update by a terminal in a wireless communication system according to an embodiment of the present disclosure comprises the steps of: receiving, by a terminal set to a radio resource control (RRC) inactive mode, radio access network-based notification area (RNA) information from a base station; when previous RNA information of the terminal and the RNA information are different, transmitting an RNA update indication message to the base station; and when the RRC inactive mode of the terminal is allowed to be maintained by the base station which has received the RNA update indication message, receiving an RNA update complete message from the base station.
