Handset transitions in a dual-mode environment
First Claim
1. A method for handling a call involving a dual-mode handset capable of operating in a cellular mode and in a voice over Internet Protocol (“
- VoIP”
) mode, the method comprising;
a dual-mode handset participating in a first call with an other party, the first call being carried on a VoIP connection with a VoIP system;
determining that a signal quality for the VoIP connection has fallen below a first threshold;
originating a second call between the VoIP system and the dual-mode handset, wherein the second call is carried by a cellular system;
answering the second call;
bridging the first call and the second call;
the dual-mode handset transitioning a microphone function and a speaker function from the first call to the second call, such that the dual-mode handset is in communication with the other party via the second call; and
disconnecting the first call.

Abstract
Embodiments of the invention provide novel solutions, including systems, methods and/or software, for handling calls in a dual-mode VoIP/cellular environment. Merely by way of example, some systems can be configured to determine whether to use a VoIP system or a cellular system to handle a particular call, and/or to transition a call from one network to the other network. Other systems can be configured to substitute a public number (which might be, for example, a VoIP number) for a private number (which might be, for example, a cellular number) when routing a call originating from a dual-mode phone on a cellular network. Further systems can be configured to allow a VoIP system to serve as an anchor for calls originated and/or delivered on a cellular system, for instance to facilitate a transition between cellular and VoIP service during a call.
