Abstract

The present invention provides a method, apparatus, and a computer program product for performing one or more minimizing drive test (MDT) measurements, defining a validity time threshold for each kind of MDT measurement, verifying, prior to reporting one of the MDT measurement results, whether the validity time threshold defined for the respective MDT measurement result to be reported, is exceeded, and, if the validity time threshold is not exceeded, reporting the MDT measurement result.

Claims

1. A method comprising:

performing one or more minimizing drive test (MDT) measurements;

defining a validity time threshold for each kind of MDT measurement;

verifying, prior to reporting one of the MDT measurement results, whether the validity time threshold defined for the respective MDT measurement result to be reported is exceeded; and

if the validity time threshold is not exceeded, reporting the MDT measurement result.

2. The method according to claim 1, further comprising:

if the validity time threshold is exceeded, deleting the corresponding MDT measurement result.

3. The method according to claim 1, further comprising:

if the validity time threshold is exceeded, adding a time stamp to the MDT measurement result, and

reporting the MDT measurement result including the added time stamp.

4. The method according to claim 3, wherein the time stamp indicates the measurement time being defined as:

“

time stamp=current time−

validity time threshold”

.

5. The method according to claim 1, wherein for each of the MDT measurements a different validity time threshold is defined.

6. A computer program product comprising a non-transitory computer-readable storage medium bearing computer program code embodied therein for use with a computer, the computer program code comprising code for performing the method according to claim 1.

7. The computer program product according to claim 6, wherein the computer program code is directly loadable into an internal memory of the computer.

8. An apparatus comprising:

at least one processor; and

at least one memory including computer program code, the at least one memory and the computer program code configured, with the at least one processor, to cause the apparatus to perform the following;

perform one or more minimizing drive test (MDT) measurements;

define a validity time threshold for each kind of MDT measurement;

verify, prior to reporting one of the MDT measurement results, whether the validity time threshold defined for the respective MDT measurement result to be reported is exceeded; and

report, if the validity time threshold is not exceeded, the MDT measurement result.

9. The apparatus according to claim 8, wherein the at least one memory and the computer program code are further configured, with the at least one processor, to cause the apparatus to delete, if the validity time threshold is exceeded, the corresponding MDT measurement result.

10. The apparatus according to claim 8, wherein the at least one memory and the computer program code are further configured, with the at least one processor, to cause the apparatus to add, if the validity time threshold is exceeded, a time stamp to the MDT measurement result, and to report the MDT measurement result including the added time stamp.

11. The method apparatus according to claim 10, wherein the time stamp indicates the measurement time being defined as:

“

time stamp=current time−

validity time threshold”

.

12. The apparatus according to claim 8, wherein the at least one memory and the computer program code are further configured, with the at least one processor, to cause the apparatus to define a different validity time threshold for each of the MDT measurements.

13. An apparatus comprising:

measuring means for performing one or more minimizing drive test (MDT) measurements;

defining means for defining a validity time threshold for each kind of MDT measurement;

verifying means for verifying, prior to reporting one of the MDT measurement results, whether the validity time threshold defined for the respective MDT measurement result to be reported, is exceeded; and

reporting means for reporting, if the validity time threshold is not exceeded, the MDT measurement result.
