Notifying a management system of quality of experience measurement reporting status

1. A method, implemented by a radio access network (RAN) node in a RAN of a wireless communication network, the method comprising:

detecting an overload condition of the RAN;

responsive to detecting the overload condition of the RAN, signaling a wireless device to stop reporting Quality of Experience (QoE) measurements to the RAN; and

notifying a management system outside of the wireless communication network that the reporting of QoE measurements to the RAN has stopped.

2. The method of claim 1 , further comprising subsequent to notifying the management system that the reporting of QoE measurements to the RAN has stopped, signaling the wireless device to restart reporting of the QoE measurements, and notifying the management system that the reporting of QoE measurements has restarted.

3. The method of claim 2 , wherein signaling the wireless device to restart reporting is responsive to detecting that the overload condition of the RAN has ended.

4. The method of claim 2 , further comprising signaling the wireless device to modify how the wireless device performs the QoE measurements.

5. The method of claim 4 , wherein signaling the wireless device to modify how the wireless device performs the QoE measurements is responsive to receiving a request from the management system to modify how the wireless device performs the QoE measurements.

6. The method of claim 5 , wherein the request from the management system to modify how the wireless device performs the QoE measurements comprises at least one QoE measurement parameter for the wireless device to use for collecting subsequent QoE measurements.

7. The method of claim 4 , wherein signaling the wireless device to modify how the wireless device performs the QoE measurements comprises signaling the wireless device to prolong a collection duration of the QoE measurements.

8. The method of claim 4 , wherein signaling the wireless device to modify how the wireless device performs the QoE measurements comprises signaling the wireless device to increase a target area of the QoE measurements.

9. The method of claim 1 , wherein notifying the management system that the reporting of QoE measurements has stopped comprises notifying the management system of a service type of the QoE measurements for which reporting has stopped.

10. The method of claim 1 , further comprising forwarding the reporting of the QoE measurements from the wireless device to a measurement collection entity in a core network of the wireless communication network.

11. A radio access network (RAN) node in a RAN of a wireless communication network, the RAN node comprising:

a processor and a memory, the memory containing instructions executable by the processor whereby the RAN node is configured to:

detect an overload condition of the RAN;

responsive to detecting the overload condition of the RAN, signal a wireless device to stop reporting Quality of Experience (QoE) measurements to the RAN; and

notify a management system outside of the wireless communication network that the reporting of QoE measurements to the RAN has stopped.

12. The RAN node of claim 11 , wherein the RAN node is further configured to, subsequent to notifying the management system that the reporting of QoE measurements to the RAN has stopped, signal the wireless device to restart reporting of the QoE measurements, and notify the management system that the reporting of QoE measurements has restarted.

13. The RAN node of claim 12 , wherein the RAN node is further configured to signal the wireless device to restart the reporting responsive to detecting that the overload condition of the RAN has ended.

14. The RAN node of claim 12 , wherein the RAN node is further configured to signal the wireless device to modify how the wireless device performs the QoE measurements.

15. The RAN node of claim 14 , wherein the RAN node is further configured to signal the wireless device to modify how the wireless device performs the QoE measurements responsive to receiving a request from the management system to modify how the wireless device performs the QoE measurements.

16. The RAN node of claim 15 , wherein the request from the management system to modify how the wireless device performs the QoE measurements comprises at least one QoE measurement parameter for the wireless device to use for collecting subsequent QoE measurements.

17. The RAN node of claim 14 , wherein to signal the wireless device to modify how the wireless device performs the QoE measurements, the RAN node is configured to signal the wireless device to prolong a collection duration of the QoE measurements.

18. The RAN node of claim 14 , wherein to signal the wireless device to modify how the wireless device performs the QoE measurements, the RAN node is configured to signal the wireless device to increase a target area of the QoE measurements.

19. The RAN node of claim 11 , wherein to notify the management system that the reporting of QoE measurements has stopped, the RAN node is configured to notify the management system of a service type of the QoE measurements for which reporting has stopped.

20. A non-transitory computer readable medium storing a computer program product for controlling a programmable Radio Access Network (RAN) node in a RAN of a wireless communication network, the computer program product comprising software instructions that, when run on the programmable RAN node, cause the programmable RAN node to:

detect an overload condition of the RAN;

responsive to detecting the overload condition of the RAN, signal a wireless device to stop reporting Quality of Experience (QoE) measurements to the RAN; and

notify a management system outside of the wireless communication network that the reporting of QoE measurements to the RAN has stopped.
