Method and apparatus for reporting a cell quality measurement result for MDT by a terminal
First Claim
1. A method of reporting a quality measurement result for minimization of drive test (MDT) by a user equipment (UE), the method comprising:
- receiving a first message including logging configuration information of the quality measurement result for MDT from a base station (BS);
performing quality measurement for MDT;
logging the quality measurement result according to the logging configuration information included in the first message;
operating a predetermined timer after logging the quality measurement result;
receiving a second message indicating whether the BS supports reporting of the logged quality measurement result from the BS;
if the second message indicates that the BS supports reporting of the logged quality measurement result, transmitting, to the BS, a third message indicating that the logged quality measurement result is present; and
if the second message indicates that the BS does not support reporting of the logged quality measurement result,stopping operation of the predetermined timer; and
transmitting, to the BS, a fourth message indicating that the logged quality measurement result is present and resuming operation of the predetermined timer, if another second message is received after stopping operation of the predetermined timer, the another second message indicating that the BS supports reporting of the logged quality measurement result.

Abstract
The present invention relates to a method and apparatus for reporting a cell quality measurement result for minimization of drive test (MDT) to a base station in an efficient manner by a terminal. The method for reporting a quality measurement result for MDT by a terminal according to one aspect of the present invention comprises: receiving from a base station a first message that contains logging configuration information of a quality measurement result for the MDT; performing quality measurement for the MDT and logging the quality measurement result according to logging configuration information contained in the first message; receiving from the base station a second message that contains information regarding whether the base station supports the report of the quality measurement result; and transmitting to the base station a message notifying the existence of the logged quality measurement result, if the second message contains the information regarding the support of the measurement result.
