CLAIMS

1. A mobile wireless communication device comprising:

a memory;

a receiver configured to receive a Minimization of Drive Test (MDT) configuration comprising criteria for performing event-based logging;

a controller configured to:

determine if the criteria have been met, and

in response to a determination that the criteria have been met, perform an MDT in accordance with the MDT configuration, and log results of the MDT in the memory as an MDT log;

a transmitter configured to transmit, to a base station, a log availability indicator indicating the availability of the MDT log.

2. The mobile wireless communication device of claim 1 , wherein the criteria comprise a defined geographical location, the criteria being met when the mobile device is at the defined geographical location.

3. The mobile wireless communication device of claim 2, wherein the criteria comprise a received signal threshold and the criteria is met when a signal strength of a received signal exceeds the received signal threshold.

4. The mobile wireless communication device of claim 2, wherein the defined geographical location is defined by a Global Positioning System (GPS) coordinates.

5. The mobile wireless communication device of claim 2, wherein the defined geographical location is defined by a street address.

6. The mobile wireless communication device of claim 2, the defined geographical location is defined by a mapping service marker code.

7. The mobile wireless communication device of claim 2, wherein the criteria comprise a defined geographical area, the criteria being met when the mobile device is located within the defined geographical area.

8. The mobile wireless communication device of claim 1 , wherein:

the receiver is further configured to receive a log retrieval request from the base station; and

the transmitter is further configured transmit the MDT log report indicative of the MDT log to the base station in response to the log retrieval request.

9. The mobile wireless communication device of claim 1 , wherein the log ability indicator indicates that the MDT log is event-based.

10. A method comprising:

receiving a Minimization of Drive Test (MDT) configuration comprising criteria for performing event-based logging;

determining if the criteria have been met;

in response to determining that the criteria have been met, performing an MDT in accordance with the MDT configuration, and log results of the MDT in the memory as an MDT log; and

transmitting, to a base station, a log availability indicator indicating the availability of the MDT log.

11. The method of claim 10, wherein the criteria comprise a defined geographical location, the criteria being met when the mobile device is at the defined geographical location.

12. The method of claim 11 , wherein the defined geographical location is defined by a Global Positioning System (GPS) coordinates.

13. The method of claim 11 , wherein the defined geographical location is defined by a street address.

14. The method of claim 11 , wherein the defined geographical location is defined by a mapping service marker code.

15. The method of claim 11 , wherein the criteria comprise a defined geographical area, the criteria being met when the mobile device is located within the defined geographical area.

16. The method of claim 10, further comprising:

receiving a log retrieval request from the base station; and

transmitting the MDT log report indicative of the MDT log to the base station in response to the log retrieval request.

17. The method of claim 10, wherein the log ability indicator indicates that the MDT log is event-based.

18. The method of claim 10, wherein the criteria comprise a received signal threshold and the criteria is met when a signal strength of a received signal exceeds the received signal threshold.
