US 9,313,817 B2 · Method for performing D2D communication and apparatus therefor

Abstract

The present invention relates to a wireless communication system. In particular, provided are a method for managing, by a terminal, mobility in a wireless communication system, and an apparatus therefore, including the steps of: receiving a plurality of TA lists, wherein the plurality of TA lists include dedicated TA lists and shared TA lists; and when TA information of a current cell matches with the shared TA lists, selectively performing a TAU process according to a communication mode, wherein when the communication mode is a non-D2D, the TAU process is performed on an MME corresponding to the TA information about the current cell, and when the communication mode is D2D, the TAU process is skipped.

A method of managing mobility by a user equipment in a wireless communication system, the method comprising:

receiving a list of a plurality of TAs (tracking areas), wherein the list of a plurality of the TAs comprises a dedicated TA list and a shared TA list;
and
if TA information of a current cell is matched with the shared TA list, selectively performing a TAU (tracking area update) process according to a communication mode,
wherein if the communication mode corresponds to a non-D2D (device to device) mode, the TAU process is performed for an MME (mobility management entity) corresponding to the TA information of the current cell and wherein if the communication mode corresponds to a D2D mode, the TAU process is skipped.
