CLAIMS

What is claimed is:

1. An apparatus of user equipment (UE), the apparatus comprising:

a memory; and

processing circuitry arranged to:

decode Radio Resource Control (RRC) signalling from an evolved NodeB (eNB);

configure the UE for Wireless Local Area network (WLAN) connection status reporting and Long Term Evolution (LTE)-WLAN aggregation (LWA), in response to RRC signalling;

perform WLAN status monitoring to determine whether a status of a WLAN connection of the LWA comprises the WLAN connection being unavailable or the WLAN connection being successfully established after a previous WLAN Connection Status Report message from the UE indicates WLAN suspension, the status stored in the memory; and

in response to a determination that the status of the WLAN connection comprises the WLAN connection being unavailable or the WLAN connection being successfully established after the previous

WLAN Connection Status Report message from the UE indicates WLAN suspension, initiate transmission of UE RRC signalling, the UE signalling comprising a WLAN Connection Status Report message, wherein the WLAN Connection Status Report message comprises the status.

2. The apparatus of claim 1, wherein:

the WLAN Connection Status Report message comprises a WLAN-Status information element that indicates the status.

3. The apparatus of claim 2, wherein the processing circuitry is further configured to:

set a value of the WLAN-Status information element to:

suspended when the WLAN connection is unavailable, and resumed when the WLAN connection is successfully established and a status of the previous WLAN Connection Status Report message is suspended.

4. The apparatus of any one or more of claims 1-3, wherein the processing circuitry is further arranged to:

determine whether the RRC signalling indicates to the UE to release the LWA configuration; and

in response to a determination that the RRC signalling indicates to the UE to release the LWA configuration, release the LWA configuration in place of initiation of the transmission of the WLAN Connection Status Report message.

5. The apparatus of claim 1, wherein:

the WLAN Connection Status Report message indicates suspended or resumed in response to the RRC signalling indicating suspension or resumption of the WLAN connection is to trigger transmission of the WLAN Connection Status Report message.

6. The apparatus of claim 1, wherein the processing circuitry is further arranged to:

perform a predetermined set of measurements on the WLAN connection dependent on whether the WLAN connection is available.

7. The apparatus of claim 6, wherein the processing circuitry is further arranged to:

initiate transmission of a measurement report that includes the measurements to the eNB dependent on which WLANs the RRC signalling indicates are to be reported, the measurements dependent on WLAN identifiers when the RRC signaling indicates that measurement reports are transmitted for fewer than all WLANs.

8. The apparatus of claim 6, wherein the processing circuitry is further arranged to:

initiate transmission of a measurement report that indicates whether the UE is connected to the WLAN.

9. The apparatus of claim 1, wherein:

the processing circuitry comprises a baseband processor configured to encode transmissions to, and decode transmissions from, the eNB.

10. An apparatus of an evolved NodeB (eNB), the apparatus comprising: a memory; and

processing circuitry arranged to:

establish communication with a user equipment (UE) using Long Term Evolution (LTE)-Wireless Local Area Network (WLAN) aggregation (LWA) comprising a WLAN connection; and

in response to a status of the WLAN connection being unavailable or the WLAN connection being successfully established after a previous WLAN Connection Status Report from the UE indicates WLAN suspension, decode a WLAN Connection Status Report message that comprises the status of the WLAN connection, a status of a last WLAN Connection Status Report message stored in the memory.

11. The apparatus of claim 10, wherein:

the WLAN Connection Status Report message comprises a WLAN-Status information element that indicates the status.

12. The apparatus of claim 11, wherein:

a value of the WLAN-Status information element is set to:

suspended when the WLAN connection is unavailable, and

resumed when the WLAN connection is successfully established and the status of the last WLAN Connection Status Report message is suspended.

13. The apparatus of claim 12, wherein:

the WLAN-Status information element indicates a status selected from suspended and resumed.

14. The apparatus of claim 13, wherein the processing circuitry is further arranged to:

encode, for transmission to the UE, RRC signalling that indicates to the UE that suspension or resumption of the WLAN connection is to trigger transmission of the WLAN Connection Status Report message.

15. The apparatus of claim 12, wherein the processing circuitry is further arranged to:

encode, for transmission to the UE, RRC signalling that indicates to the UE to release the LWA configuration, the LWA configuration released in place of reception of the WLAN Connection Status Report message.

16. The apparatus of claim 12, wherein the processing circuitry is further arranged to:

decode the transmission of the WLAN Connection Status Report message with the value resumed in response to the WLAN connection being successfully established after being unavailable.

17. The apparatus of any one or more of claims 10-16, wherein the processing circuitry is further arranged to:

encode, for transmission to the UE, RRC signalling that indicates to the UE that WLAN measurements are dependent on WLAN identifiers; and

decode a measurement report containing the measurements from the UE in response to the WLAN connection failing matching the WLAN identifiers.

18. The apparatus of any one or more of claims 10-16, wherein the processing circuitry is further arranged to:

encode, for transmission to the UE, RRC signalling that indicates to the

UE that WLAN measurements are to be made for all WLANs; and

decode a measurement report containing measurements from the UE in response to the UE being connected to the WLAN.

19. A non-transitory computer-readable storage medium that stores instructions for execution by one or more processors of a user equipment (UE), the one or more processors to configure the UE to, when the instructions are executed:

establish communication with an evolved NodeB (eNB) through Long Term Evolution (LTE)-Wireless Local Area network (WLAN) aggregation (LWA) comprising an LTE connection and a WLAN connection;

determine whether a status of a WLAN connection of the LWA comprises the WLAN connection being unavailable or the WLAN connection being successfully established after a previous WLAN Connection Status Report from the UE indicates WLAN suspension; and

in response to a determination that the status of the WLAN connection comprises the WLAN connection being unavailable or the WLAN connection being successfully established after being unavailable, initiate transmission of a WLAN Connection Status Report message, the WLAN Connection Status Report message comprising a WLAN-Status information element having a status selected from:

suspended when the WLAN connection is unavailable, and

resumed when the WLAN connection is successfully established and a status of a last WLAN Connection Status Report message is suspended.

20. The medium of claim 19, wherein the instructions further configure the one or more processors to configure the UE to:

initiate the transmission of the WLAN Connection Status Report message that indicates resumed in response to the WLAN connection being successfully established after being unavailable prior to reception from the eNB of a message to release a LWA configuration.
