Abstract

The present invention relates to a method and apparatus for reporting a logged measurement in a wireless communication system. A terminal receives a minimization of drive tests (MDT) configuration from a cell of a first radio access technology (RAT), and logs a measurement based on the MDT configuration so as to collect the logged measurements. The terminal transmits a logging indicator, which indicates the availability of the logged measurements, to a cell of a second RAT.

Claims

1. A method of reporting logged measurements in a wireless communication system, the method comprising:

receiving, by a user equipment, a minimization of drive tests (MDT) configuration from a cell of a first radio access technology (RAT);

logging, by the user equipment, measurements based on the MDT configuration in order to collect the logged measurements; and

transmitting, by the user equipment, a logging indicator indicating an availability of the logged measurements to a cell of a second RAT.

2. The method of claim 1, wherein the user equipment logs the measurements in a radio resource control (RRC) idle mode.

3. The method of claim 2, wherein the logging indicator indicates the first RAT at which the MDT configuration is received.

4. The method of claim 3, further comprising:

transmitting, by the user equipment, from the RRC idle mode into an RRC connection mode prior to transmitting the logging indicator.

5. The method of claim 4, further comprising:

receiving, by the user equipment, a reporting request for reporting the logged measurements from the cell of the second RAT; and

transmitting, by the user equipment, a measurement result including the logged measurements to the cell of the second RAT in response to the reporting request.

6. The method of claim 5, wherein the reporting request includes information indicating the MDT configuration or information indicating the first RAT at which the MDT configuration is received.

7. The method of claim 6, wherein the measurement result further includes the MDT configuration.

8. The method of claim 1, wherein the first RAT or the second RAT is one of GSM EDGE Radio Access Network (GERAN), Universal Terrestrial Radio Access Network (UTRAN), and Evolved-UTRAN(E-UTRAN).

9. A wireless apparatus for reporting logged measurements in a wireless communication system, the wireless apparatus comprising:

a radio frequency (RF) unit configured to transmit and receive a radio signal; and

a processor operably connected to the RF unit and configured to;

receive a minimization of drive tests (MDT) configuration from a cell of a first radio access technology (RAT);

log, measurements based on the MDT configuration in order to collect the logged measurements; and

transmit a logging indicator indicating an availability of the logged measurements to a cell of a second RAT.

10. The wireless apparatus of claim 9, wherein the logging indicator indicates the first RAT at which the MDT configuration is received.

11. The wireless apparatus of claim 10, wherein the processor is configured to receive a reporting request for reporting the logged measurements from the cell of the second RAT, and transmit a measurement result including the logged measurements to the cell of the second RAT in response to the reporting request.

12. The wireless apparatus of claim 11, wherein the reporting request includes information indicating the MDT configuration or information indicating the first RAT at which the MDT configuration is received.

13. The wireless apparatus of claim 12, wherein the measurement result further includes the MDT configuration.

14. The wireless apparatus of claim 9, wherein the first RAT or the second RAT is one of GSM EDGE Radio Access Network (GERAN), Universal Terrestrial Radio Access Network (UTRAN), and Evolved-UTRAN(E-UTRAN).
