ABSTRACT:
Methods and apparatus for use by a mobile communication device in facilitating voice calls through a wireless local area network (WLAN) and a wireless wide area network (WWAN) are disclosed. When switching communication operations from a WLAN coverage region of the WLAN to a WWAN coverage region of the WWAN, the mobile device causes a message for forwarding voice calls to a WWAN identification number of the mobile device to be transmitted through the WLAN. The mobile device subsequently causes a message for cancelling the forwarding of voice calls to a WLAN identification number of the mobile device to be transmitted through the WWAN. When switching communication operations from the WWAN coverage region of the WWAN to the WLAN coverage region of the WLAN, the mobile device causes a message for forwarding voice calls to the WLAN identification number of the mobile device to be transmitted through the WWAN. The mobile device subsequently causes a message for cancelling the forwarding of voice calls to the WWAN telephone number of the mobile device to be transmitted through the WLAN. Other additional and alternative techniques are described for reliable reachability.
