Handset registration in a dual-mode environment
First Claim
1. A method for handling a call involving a dual-mode phone capable of operating in a cellular mode and in a voice over Internet Protocol (“
- VoIP”
) mode, the system comprising;
a dual-mode phone registering with a cellular system;
the dual-mode phone registering with a VoIP system; and
the dual-mode simultaneously maintaining active registrations with the cellular system and with the VoIP system.

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.

2. A method for handling a call involving a dual-mode phone capable of operating in a cellular mode and in a voice over Internet Protocol (“
- VoIP”
) mode, the method comprising;
a dual-mode phone participating in a first call with another 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 phone, wherein the second call is carried by the cellular system;
answering the second call;
bridging the first call and the second call;
the phone transitioning a microphone function and a speaker function from the first call to the second call, such that the phone is in communication with the other party via the second call; and
disconnecting the first call. - View Dependent Claims (3, 4, 5)

6. A telecommunication system for handling a call involving a dual-mode phone capable of operating in a cellular mode and in a voice over Internet Protocol (“
- VoIp”
) mode, the system comprising;
a dual-mode phone;
a VoIP system configured to provide VoIP service to the dual-mode phone; and
a cellular system configured to provide cellular service to the dual-mode phone;
wherein the VoIP system is configured to;
determine that a signal quality for the VoIP connection has fallen below a first threshold;
answer a second call originated by the dual-mode phone and carried by the cellular system;
bridge the first call and the second call; and
disconnect the first call. - View Dependent Claims (7, 8)

9. A method for handling a call involving a dual-mode phone capable of operating in a cellular mode and in a voice over Internet Protocol (“
- VoIP”
) mode, the method comprising;
determining whether the signal quality of a connection between a dual-mode phone and a VoIP system is above a first threshold;
if the signal quality of the connection is above the first threshold, registering the dual-mode phone with the VoIP system;
determining whether the signal quality of the connection is above a second threshold;
if the signal quality of the connection is not above the second threshold, deregistering the dual-mode phone from the VoIP system. - View Dependent Claims (10, 11, 12, 13)
