Abstract
Handover of a call to a dual-mode phone from cellular to Wi-Fi. When handing over a call mediated by a mobility controller to a dual-mode phone and switching the call from a cellular to a Wi-Fi call, the mobility controller initiates a Wi-Fi connection to the dual mode phone. When the Wi-Fi connection is established, and with the cellular connection through the mobility controller still in place, the mobility controller starts a timer with a predetermined value and the dual-mode phone initiates release of the cellular connection. When the timer expires, the mobility controller switches the call from the cellular connection to the Wi-Fi connection.
