Abstract

Provided is a method for executing a minimization drive test (MDT) carried out by a terminal in a wireless communication system. The method comprises: receiving a logged measurement setting; logging an MDT measurement and a measurement result on the basis of the logged measurement setting; and reporting the whole or a part of the logged measurement result to a network. The logged measurement setting includes logging termination time information for indicating the termination time of the MDT measurement or the measurement result logging, wherein the MDT measurement and the measurement result is logged by the time indicated by the logging termination time information.

Claims

1. A method of performing, by user equipment (UE), a Minimization Drive Test (MDT) in a wireless communication system, the method comprising:

receiving a logged measurement configuration;

performing MDT measurement and logging a measurement result based on the logged measurement configuration; and

reporting all or part of the logged measurement result to a network,

wherein the logged measurement configuration comprises logging end time information indicating that the MDT measurement and the measurement result logging are ended, and

wherein the steps of performing the MDT measurement and logging the measurement result are performed until the time indicated by the logging end time information.

2. The method of claim 1, further comprising,

discarding the logged measurement configuration when the end time indicated by the logging end time information elapses.

3. The method of claim 2, wherein the logged measurement configuration further comprises logging start time information indicative of a start time when performing the MDT measurement and logging the measurement result are allowed.

4. The method of claim 3, wherein the steps of performing the MDT measurement and logging the measurement result are performed when the start time indicated by the logging start time information is reached and until the end time indicated by the logging end time information.

5. The method of claim 4,

wherein the logged measurement configuration comprises logging interval information, the logging interval information indicates a specific time interval, and

wherein the step of performing the MDT measurement and logging the measurement result are periodically performed in accordance with the specific time interval.

6. The method of claim 5, wherein the UE is in a Radio Resource Control (RRC) idle state at a point of time at which the MDT measurement is performed and the measurement result is logged.

7. The method of claim 1,

wherein the logged measurement configuration further comprises log report end time information, and

wherein the log report end time information indicates an end time when the report is ended.

8. The method of claim 7, further comprising discarding remaining logged measurement result if the end time indicated by the log report end time information elapses and the remaining logged measurement result not reported is present in the logged measurement result.

9. The method of claim 8,

wherein the logged measurement configuration further comprises log report start time information, and

wherein the log report start time information indicates a start time when the report is allowed.

10. The method of claim 9, wherein the report is performed when the start time indicated by the log report start time is reached and until the end time indicated by the log report end time.

11. The method of claim 10, wherein at a point of time at which part of or the entire logged measurement is reported, the UE is in an RRC_connected state.

12. A wireless apparatus comprising:

a Radio Frequency (RF) unit transmitting and receiving radio signals; and

a processor operably coupled to the RF unit, wherein the processor is configured to;

receive a logged measurement configuration;

perform a Minimization Driving Test (MDT) measurement and log a measurement result based on the logged measurement configuration; and

report all or a part of the logged measurement result to a network,

wherein the logged measurement configuration comprises logging end time information indicating that the MDT measurement and the measurement result logging are ended, and

wherein the performing the MDT measurement and the logging the measurement result are performed until the time indicated by the logging end time information.

13. The wireless apparatus of claim 12, wherein the processor is configured to discard the logged measurement configuration when the end time indicated by the logging end time information elapses.

14. The wireless apparatus of claim 13, wherein the logged measurement configuration further comprises logging start time information indicative of a start time when performing the MDT measurement and logging the measurement result are allowed.

15. The wireless apparatus of claim 14, wherein the performing the MDT measurement and the logging the measurement result are performed when the start time indicated by the logging start time information is reached and until the end time indicated by the logging end time information.

16. The wireless apparatus of claim 15, wherein the wireless apparatus is in a Radio Resource Control (RRC) idle state at a point of time at which the MDT measurement is performed and the measurement result is logged.

17. The wireless apparatus of claim 12,

wherein the logged measurement configuration further comprises log report end time information, and

wherein the log report end time information indicates an end time when the report is ended.

18. The wireless apparatus of claim 17, wherein the processor is further configured to:

discard remaining logged measurement result if the end time indicated by the log report end time information elapses and the remaining logged measurement result not reported is present in the logged measurement result.

19. The wireless apparatus of claim 18,

wherein the logged measurement configuration further comprises log report start time information, and

wherein the log report start time information indicates a start time when the report is allowed.

20. The wireless apparatus of claim 19, wherein the report is performed when the start time indicated by the log report start time is reached and until the end time indicated by the log report end time.

21. The wireless apparatus of claim 20, wherein at a point of time at which all or a part of the logged measurement is reported, the UE is in an RRC_connected state.
