Abstract
A gateway serving as an interface between a mobile network and a wireless network can be configured to send a signal strength indicator to the mobile network thereby causing the mobile network to recognize the gateway as a valid path for handing off a call. The wireless network can be configured according to one of the 802.11 wireless communications protocols. The gateway can route the call from the mobile network to a wireless access point of the wireless network via a packet-switched network, such that the call is conducted via a wireless communications link with the wireless access point.

7. Within a gateway interface, a method of call control between a mobile network and a wireless network comprising:
-
establishing, with a mobile network, a control messaging link for exchanging mobile control channel signaling data and a voice channel link for exchanging audio data for a mobile call;
sending a signal strength indicator to the mobile network thereby causing the mobile network to recognize the gateway as a valid path for handing off the mobile call;
establishing a communications link with a packet-switched network; and
routing the mobile call from the mobile network to a wireless access point via the packet-switched network, such that the call is conducted via a wireless communications link using the wireless access point. - View Dependent Claims (8, 9, 10)
