Method, user equipment and network for performing a handover for user equipments in peer-to-peer communication mode, to a cell whose link performance is a predefined value higher than that of the active cell

摘要

A method to be executed by a UE (user equipment) is proposed, for said UE in P2P communication mode to perform cell handover, comprising steps of: detecting downlink signals of the active cell in which said UE is camping and its adjacent cells (S 205 ); judging whether there exists a suitable cell whose link performance is a predefined value higher than that of said active cell (S 209 ), according to the detecting result; sending a detection report message to a network system (S 210 ) to start a judging procedure of said network system if there exists said suitable cell, and said judging procedure deciding whether said UE and another UE in P2P communication can handover into said suitable cell to continue P2P communication.
