Single Number Presentation for Dual-Mode Phones
Granted: June 18, 2009
Application Number:
20090156164
Providing a single number presentation to the party called by a dual-mode phone. The operation of the cellular side of a dual-mode phone is altered such that when the user attempts to place an outgoing call using the cellular phone, the call is redirected to a preprogrammed incoming phone number associated with the enterprise. When the enterprise PBX answers this call, the dual-mode phone transmits the desired number to the enterprise PBX. The enterprise PBX then places the call to the…
Single Voicemail For Dual-Mode Phones
Granted: June 18, 2009
Application Number:
20090156175
Single voicemail for dual-mode phones. Functionality is added to a dual-mode phone such that the dual-mode phone when operating in cellular mode sends a predetermined signal when it answers an incoming call. An enterprise mobility controller, on forwarding a call to the cellular side of a dual-mode phone after failing to complete a Wi-Fi connection, starts a timer. If the mobility controller does not receive the predetermined signal before the timer expires, it assumes that the cellular…
Delayed ACK in dual-mode call handover
Granted: June 18, 2009
Application Number:
20090156217
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 initates 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…
