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 of the plurality access points 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. Based on the RL information, the WLAN controller 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 from the WWAN system to access points in the mesh network.
