Abstract

Disclosed is a wireless communication system and terminal for providing a wireless communication service, and more particularly, a method of effectively perform an operation of MDT (Minimization Driving Test) for a specific area or a specific cell in an Evolved Universal Mobile Telecommunications System (E-UMTS) evolved from a UMTS, Long Term Evolution (LTE) System or LTE-Advanced (LTE-A) system.

Claims

1. A method of performing a measurement in a wireless communication system, the method comprising:

receiving, by a user equipment (UE) that is in a Radio Resource Control (RRC) connected mode, a measurement configuration from a network via a dedicated RRC message, the measurement configuration including a list of cell identifiers (IDs) for which one or more UEs are requested to perform a measurement logging while in an RRC idle mode;

after receiving the measurement configuration, receiving, by the UE, system information from the network, the system information including a cell ID of a cell of the UE;

comparing the cell identifier of the system to the list of cell IDs;

performing, by the UE while in a RRC idle mode, the measurement logging if the cell indicated by the cell identifier of the system information is included within the list of cell IDs IDs according to the comparing; and

reporting a logged measurement result including the cell identifier to the network in the RRC connected mode.

2. The method of claim 1, wherein the measurement configuration is a minimization driving test (MDT) configuration.

3. The method of claim 1, wherein the measurement configuration indicates a triggering condition of the measurement logging.

4. An apparatus for performing a measurement in a wireless communication system, the apparatus comprising:

a transceiver to transmit or receive a data;

a memory to store the data; and

a processor configured to cooperate with the transceiver and the memory to;

receive, while in a Radio Resource Control (RRC) connected mode, a measurement configuration from a network via a dedicated RRC message, the measurement configuration including a list of cell identifiers (IDs) for which one or more UEs are requested to perform a measurement logging while in an RRC idle mode;

after receiving the measurement configuration, receive system information from the network, the system information including a cell ID of a cell of the UE;

compare the cell identifier of the system to the list of cell IDs;

perform, while in a RRC idle mode, the measurement logging if the cell indicated by the cell identifier of the system information is included within the list of cell IDs according to the comparing; and

report a logged measurement result including the cell identifier to the network in the RRC connected mode.

5. The apparatus of claim 4, wherein the measurement configuration is a minimization driving test (MDT) configuration.
