Abstract

A mesh network communication system includes a plurality of access points connected to a wireless local area network (WLAN) controller where at least one access point is a detection access point (DAP) that receives reverse link (RL) wireless wide area network (WWAN) signals transmitted from a multi-mode wireless communication device. Based on an intercepted RL WWAN signal, the DAP forwards reverse link (RL) information to the WLAN controller, which then generates and sends, to the WWAN communication system, a device to access point association list (device-AP association list) comprising one or more device identifiers associated with one or more target access point identifier. The device identifier uniquely identifies a multi-mode wireless communication device within a maximum proximity of a target access point identified by the target access point identifier. The WWAN system applies the device-AP association list to efficiently manage handoffs to access points in the mesh network.

Claims

1. A wireless wide area network (WWAN) system comprising:

an access gateway configured to receive a device to access point association list (device-AP association list) generated by a wireless local area network (WLAN) controller based on a reverse link (RL) WWAN signal received at a WLAN access point, the WLAN controller connected to a plurality of WLAN access points to form a mesh network, the device-AP association list comprising a device identifier associated with a target access point identifier, the device identifier uniquely identifying, based on the reverse link (RL) WWAN signal received through a wireless link at the WLAN access point, a target multi-mode wireless communication device within a maximum proximity of a target access point identified by the target access point identifier.

2. The WWAN system of claim 1, further comprising a processor configured to initiate a handoff procedure of the target multi-mode wireless communication device from the WWAN system to the mesh network in response to the device-AP association list.

3. The WWAN system of claim 2, wherein the device-AP association list comprises a plurality of target access point identifiers and a plurality of device identifiers and at least one of the device identifiers is associated with two or more target access point identifiers, the processor configured to initiate the handoff procedure to a target access point identified by one of the two or more target access point identifiers.

4. The WWAN system of claim 2, wherein the processor is further configured to determine, based on a quality of service (QoS) requirement of the target multi-mode wireless communication device, whether the handoff procedure should be initiated.

5. The WWAN system of claim 1, further comprising a processor configured to initiate a procedure to establish wireless communication service between the target multi-mode wireless communication device and the target access point while maintaining communication with the WWAN system to enable the target access point to simultaneously receive wireless service from the WWAN and the WLAN.

6. The WWAN system of claim 1, wherein the access gateway is configured to receive the device-AP association list through an Internet Protocol (IP) network.

7. The WWAN system of claim 1, wherein the access gateway is configured to wirelessly receive the device-AP association list.

8. The WWAN system of claim 7, further comprising a WWAN receiver, wherein the access gateway is configured to wirelessly receive the device-AP association list by receiving another RL WWAN signal comprising the device-AP association list and transmitted by a WWAN transmitter connected to the WLAN controller.
