METHOD OF SUPPORTING MOBILITY OF UE SUPPORTING/USING D2D COMMUNICATION IN WIRELESS MOBILE COMMUNICATION SYSTEM

摘要

Disclosed is a method of supporting/using Device-to-Device (D2D) communication supporting user equipment (UE) mobility in a wireless mobile communication system. A method and an apparatus for performing D2D communication includes receiving system information of at least one of a serving cell and an adjacent cell of the UE. The method and apparatus for performing D2D communication also includes determining whether cell redirection is required to perform the direct communication based on the system information. The method and apparatus for performing D2D communication further includes performing the cell redirection on the adjacent cell when the cell redirection is required according to a result of the determination.
