Abstract

Methods and apparatus to perform measurements are disclosed. An example method disclosed herein for a user equipment (UE) to perform measurements in a mobile communication network comprises receiving configuration information comprising at least one of a validity state, a measurement activation criterion, a measurement deactivation criterion, a reporting criterion or a location request criterion to configure a measurement, and performing the measurement based on the configuration information.

Claims

1. A method for a user equipment (UE) to perform measurements in a mobile communication network, the method comprising:

receiving measurement configuration information comprising at least one of a validity state, a measurement activation criterion, a measurement deactivation criterion, a reporting criterion or a location request criterion; and

performing the measurement according to the configuration information.

2. A method as defined in claim 1 further comprising reporting the measurement.

3. A method as defined in claim 1 wherein the activation condition comprises at least one of a threshold, a target area, an access class, a positioning capability or a measurement probability factor.

4. A method as defined in claim 1 wherein the deactivation condition comprises at least one of a threshold, a target area or a duration.

5. A method as defined in claim 1 wherein the measurement comprises a periodic downlink pilot measurement.

6. A method as defined in claim 1 wherein the configuration information further comprises an indication that the UE is to remove measurement data corresponding to the measurement from a maintained measurement log when the measurement is deactivated based on a second deactivation threshold but not a first deactivation threshold, and wherein the method further comprises removing the measurement corresponding to the measurement from the maintained measurement log when the measurement is deactivated based on the second deactivation threshold but not when the measurement is deactivated based on the first deactivation threshold.

7. A method as defined in claim 1 wherein the reporting criteria comprises at least one of an event identity, a reporting range, a reporting probability factor or a positioning capability.

8. A method as defined in claim 1 wherein the location request criteria comprises at least one of an event identity, a reporting range, a positioning probability factor or a positioning capability.

9. A method as defined in claim 1 wherein the configuration information is received from a network element using radio resource control (RRC) signaling.

10. A tangible machine readable medium storing machine readable instructions which, when executed, cause a machine to:

receive configuration information comprising at least one of a validity state, a measurement activation criterion, a measurement deactivation criterion, a reporting criterion or a location request criterion to configure a measurement to be performed in a mobile communication network; and

perform the measurement based on the configuration information.

11. A tangible machine readable medium as defined in claim 10 wherein the machine readable instructions, when executed, further cause the machine to report the measurement.

12. A tangible machine readable medium as defined in claim 10 wherein the activation condition comprises at least one of a threshold, a target area, an access class, a positioning capability or a measurement probability factor.

13. A tangible machine readable medium as defined in claim 10 wherein the deactivation condition comprises at least one of a threshold, a target area or a duration.

14. A tangible machine readable medium as defined in claim 10 wherein the configuration information further comprises obtain an indication that the machine is to remove measurement data corresponding to the measurement from a maintained measurement log when the measurement is deactivated based on a second deactivation threshold but not a first deactivation threshold, and wherein the machine readable instructions, when executed, further cause the machine to remove the measurement corresponding to the measurement from the maintained measurement log when the measurement is deactivated based on the second deactivation threshold but not when the measurement is deactivated based on the first deactivation threshold.

15. A tangible machine readable medium as defined in claim 10 wherein the reporting criteria comprises at least one of an event identity, a reporting range, a reporting probability factor or a positioning capability.

16. A tangible machine readable medium as defined in claim 10 wherein the location request criteria comprises at least one of an event identity, a reporting range, a positioning probability factor or a positioning capability.

17. An apparatus to perform measurements in a mobile communication network, the apparatus comprising:

a processor configured to;

receive configuration information comprising at least one of a validity state, a measurement activation criterion, a measurement deactivation criterion, a reporting criterion or a location request criterion to configure a measurement; and

perform the measurement based on the configuration information.

18. An apparatus as defined in claim 17 wherein the processor is further configured to report the measurement.

19. An apparatus as defined in claim 17 wherein the activation condition comprises at least one of a threshold, a target area, an access class, a positioning capability or a measurement probability factor.

20. An apparatus as defined in claim 17 wherein the deactivation condition comprises at least one of a threshold, a target area or a duration.

21. An apparatus as defined in claim 17 wherein the configuration information further to obtain an indication that the apparatus is to remove measurement data corresponding to the measurement from a maintained measurement log when the measurement is deactivated based on a second deactivation threshold but not a first deactivation threshold, and wherein the processor is further configured to remove the measurement corresponding to the measurement from the maintained measurement log when the measurement is deactivated based on the second deactivation threshold but not when the measurement is deactivated based on the first deactivation threshold.

22. An apparatus as defined in claim 17 wherein the reporting criteria comprises at least one of an event identity, a reporting range, a reporting probability factor or a positioning capability.

23. An apparatus as defined in claim 17 wherein the location request criteria comprises at least one of an event identity, a reporting range, a positioning probability factor or a positioning capability.
