Method and apparatus for delivering measurement results information in a mobile communication system

PURPOSE: A method and apparatus for delivering measurement result information in a mobile communication system are provided to deliver the measurement result information to a serving base station or a target base station before performing a handover operation. CONSTITUTION: A serving base station receives the measurement report including the measurement result about one or more cells from a UE(User Equipment)(S413). The serving base station determines the handover based on the received measurement report. If the hand over is determined, the serving base station transmits the handover request message to the Target base station(S414). The handover request message comprises the measurement result about one or more cells. The measurement result is included in the RRC(Radio Resource Control) context information element of the handover request message.
