Abstract

Systems, methods, apparatuses, and computer program products for wireless local area network (WLAN) radio link failure (RLF) triggering are provided.

Claims

1. A method, comprising:

initiating a wireless local area network status report to a network node; and

indicating, to the network node, a trigger of the wireless local area network status report.

2. The method as in claim 1, wherein the trigger of the wireless local area network status report is a radio link failure.

3. The method as in claim 1, wherein the status report is initiated by receiving a wireless local area network management frame which indicates a service set change outside of a network node configured mobility domain wherein the mobility domain is a group of access points for which user equipment'"'"'s autonomous wireless local area network mobility is allowed.

4. The method as in claim 1, wherein the status report is initiated by a change in mobility domain to a domain outside of a network node configured mobility domain wherein the mobility domain is a group of access points for which user equipment'"'"'s autonomous wireless local area network mobility is allowed.

5. The method as in claim 1, wherein the status report is initiated by a change in at least one of wireless local area network operating class and frequency channel, which is allowed for the user equipment'"'"'s autonomous wireless local area network operation.

6. The method as in claim 1, wherein the status report is initiated by receiving a go to cellular signaling from a serving wireless local area network which on-loads traffic from the wireless local area network to a cellular network.

7. The method as in claims 1, wherein the initiating of wireless local area network status report is configured by the network node.

8. An apparatus, comprising:

at least one data processor; and

at least one memory including computer program code, where the at least one memory and computer program code are configured, with the at least one data processor, to cause the apparatus at least to;

initiate a wireless local area network status report to a network node; and

indicate, to the network node, a trigger of the wireless local area network status report.

9. The apparatus as in claim 8, wherein the trigger of the wireless local area network status report is a radio link failure.

10. The apparatus as in claim 8, wherein the status report is initiated by receiving a wireless local area network management frame which indicates a service set change outside of a network node configured mobility domain wherein the mobility domain is a group of access points for which the apparatus'"'"'s autonomous wireless local area network mobility is allowed.

11. The apparatus as in claim 8, wherein the status report is initiated by a change in mobility domain to a domain outside of a network node configured mobility domain wherein the mobility domain is a group of access points for which the apparatus'"'"'s autonomous wireless local area network mobility is allowed.

12. The apparatus as in claim 8, wherein the status report is initiated by a change in at least one of wireless local area network operating class and frequency channel, which is allowed for the apparatus'"'"'s autonomous wireless local area network operation.

13. The apparatus as in claim 8, wherein the status report is initiated by receiving a go to cellular signaling from a serving wireless local area network which on-loads traffic from the wireless local area network to a cellular network.

14. The apparatus as in claim 8, wherein the initiating of wireless local area network status report is configured by the network node.

15. A method comprising:

configuring a user equipment to trigger a wireless local area network status report; and

receiving the wireless local area network status report and a trigger of the wireless local area network status report from the user equipment.

16. The method as in claim 15, wherein the trigger of the wireless local area network status report is a radio link failure.

17. The method as in claim 15, wherein the status report is initiated by a wireless local area network management frame which causes a service set change of the user equipment outside of a configured mobility domain wherein the mobility domain is a group of access points for which user equipment'"'"'s autonomous wireless local area network mobility is allowed.

18. An apparatus, comprising:

at least one data processor; and

at least one memory including computer program code, where the at least one memory and computer program code are configured, with the at least one data processor, to cause the apparatus to;

configure a user equipment to trigger a wireless local area network status report; and

receive the wireless local area network status report and a trigger of the wireless local area network status report from the user equipment.

19. The apparatus as in claim 18, wherein the trigger of the wireless local area network status report is a radio link failure.

20. The apparatus as in claim 18, wherein the status report is initiated by a wireless local area network management frame which causes a service set change of the user equipment outside of a configured mobility domain wherein the mobility domain is a group of access points for which user equipment'"'"'s autonomous wireless local area network mobility is allowed.
