Abstract
Methods and systems for providing a WLAN-BTS gateway are disclosed. A handset registers with a WLAN-BTS gateway. The handset then initiates a call by initiating layer 3 air interface signaling with a BTS. The gateway forwards the layer 3 air interface signaling between the gateway and the handset. The gateway learns the control channel and traffic channel allocated to the call, either directly from the layer 3 signaling or from a separate message received from the handset. Once the call is connected, the gateway listens on the traffic channel and forwards voice packets between the handset and the BTS. Communications with the BTS occur over the allocated traffic channel. Communications with the handset occur over a WLAN.
