Handset transitions in a dual-mode environment
First Claim
1. A dual-mode phone capable of operating in a cellular mode and in a voice over Internet Protocol (“
- VoIP”
) mode, wherein the dual-mode phone comprises a processor and a memory storing instructions that, when executed by the processor, causes the processor to;
determine whether the signal quality of a connection between the dual-mode phone and a VoIP system is above a first threshold;
if the signal quality of the connection is above the first threshold, registers the dual-mode phone with the VoIP system;
determine whether the signal quality of the connection is above a second threshold;
if the dual-mode phone is not registered with a cellular system and signal quality of the connection is not above the second threshold, deregisters the dual-mode phone from the VoIP systemwherein the dual-mode phone further determines whether the dual-mode phone is registered with a cellular system, wherein, if the dual-mode phone is not registered with the cellular system, the first threshold and the second threshold are not enforced, such that the dual-mode phone registers with the VoIP system and maintains a registration with the VoIP system so long as there is sufficient signal to maintain a connection between the VoIP system and the dual-mode phone, regardless of whether the signal quality falls below the first threshold or the second threshold.

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.
