Abstract

Systems and methods are disclosed herein that relate to Quality of Experience (QoE) measurement configuration and reporting in a cellular communications system during mobility. In one embodiment, a method performed by a User Equipment (UE) comprises receiving a QoE measurement configuration and a measurement duration time associated to the QoE measurement configuration, starting to perform QoE measurements in accordance with the QoE measurement configuration, starting a measurement duration timer upon starting to perform the QoE measurements, the measurement duration timer being initialized to the measurement duration time associated to the QoE measurement configuration, and continuing to perform the QoE measurements while the measurement duration timer is running. Embodiments related to the method of operation of a RAN node are also disclosed.

First claim

1 . A method performed by a User Equipment, UE, the method comprising:
receiving a Quality of Experience, QoE, measurement configuration and a measurement duration time associated to the QoE measurement configuration; starting to perform QoE measurements in accordance with the QoE measurement configuration; starting a measurement duration timer upon starting to perform the QoE measurements, the measurement duration timer being initialized to the measurement duration time associated to the QoE measurement configuration; and continuing to perform the QoE measurements while the measurement duration timer is running.

2 . The method of claim 1 further comprising stopping performance of the QoE measurements upon expiration of the measurement duration timer.

3 . The method of claim 1 wherein receiving the QoE measurement configuration and the measurement duration time associated to the QoE measurement configuration comprises receiving the QoE measurement configuration and the measurement duration time associated to the QoE measurement from a Radio Access Network, RAN, node.

4 . The method of claim 1 wherein receiving the QoE measurement configuration and the measurement duration time associated to the QoE measurement configuration comprises:
receiving the QoE measurement configuration from a Radio Access Network, RAN, node; and
receiving the measurement duration time from an external system.

5 . The method of claim 4 further comprising providing the measurement duration time to a Radio Access Network, RAN, node.

6 . The method of claim 1 further comprising:
detecting presence of one or more conditions for pausing the QoE measurements; and
upon detecting the presence of the one or more conditions:
pausing the QoE measurements; and
pausing the measurement duration timer.

7 . The method of claim 6 wherein the one or more conditions for pausing the QoE measurements comprise: the UE moving to an inactive state, suspension of a service(s) for which QoE measurements need to be collected is(are) suspended, or occurrence of a period in which a respective session is ongoing but there is no uplink or downlink traffic being exchanged for the session for a predefined or preconfigured amount of time.

8 . The method of claim 6 further comprising sending, to the RAN node, an indication that the measurement duration timer associated to the QoE measurement configuration has been paused.

9 . The method of claim 6 further comprising:
detecting an end of the one or more conditions for pausing the QoE measurements; and
upon detecting the end of the one or more conditions for pausing the QoE measurements:
resuming the QoE measurements in accordance with the QoE measurement configuration; and
resuming the measurement duration timer.

10 . The method of claim 9 further comprising sending, to a RAN node, an indication that the measurement duration timer associated to the QoE measurement configuration has resumed.

11 . The method of claim 1 further comprising sending, to the RAN node, an indication that the measurement duration timer has started upon starting the measurement duration timer.

12 . The method of claim 1 further comprising sending, to the RAN node, one or more indications that the QoE measurements are being performed while the measurement duration timer is running.

13 . The method of claim 1 further comprising sending, to a RAN node, an indication that the measurement duration timer has expired upon expiration of the measurement duration timer.

14 . The method of claim 1 further comprising connecting to a second RAN node as a result of a handover procedure prior to expiration of the measurement duration timer.

15 . The method of claim 14 wherein the measurement duration timer continues to run during the handover procedure.

16 . The method of claim 14 wherein the measurement duration timer is paused prior to the handover procedure and resumed after the handover procedure.

17 . The method of claim 14 further comprising providing, to the second RAN node during or immediately following the handover procedure, information that indicates that the UE has an active QoE measurement configuration.

18 . The method of claim 14 further comprising providing, to the second RAN node during or immediately following the handover procedure, information that indicates a status or state of the measurement duration timer.

19 - 21 . (canceled)

22 . A User Equipment, UE, adapted to:
receive a Quality of Experience, QoE, measurement configuration and a measurement duration time associated to the QoE measurement configuration; start to perform QoE measurements in accordance with the QoE measurement configuration; start a measurement duration timer upon starting to perform the QoE measurements, the measurement duration timer being initialized to the measurement duration time associated to the QoE measurement configuration; and continue to perform the QoE measurements while the measurement duration timer is running.
