Abstract:
1. A system for switching a call session, the system comprising: an 802.1x network; a cellular network; a media gateway in communication with the 802.1x network and the cellular network; a wireless device connected to the 802.1x network by a first connection, the 802.1x network connecting the wireless device to a terminating station through the media gateway to create a call session, the wireless device measuring a first signal strength of the 802.1x network and a second signal strength of the cellular network; and a call control server, the call control server receiving the first signal strength and the second signal strength, the call control server containing logic to determine whether the second signal strength exceeds the first signal strength by an amount, wherein if the second signal strength exceeds the first signal strength by the amount the call control server causes the media gateway to switch the wireless device from the first connection to a second connection to the cellular network, and if the second signal strength does not exceed the first signal strength by the amount the wireless device remains connected through the first connection, wherein the amount may be adjusted at the wireless device by increasing or decreasing the amount.
