Methods of delivering calls on dual-mode wireless handsets
First Claim
1. In a telecommunications system comprising a cellular system and a voice over Internet Protocol (“
- VoIP”
) system, a method for handling a call placed by a dual-mode phone capable of operating in a cellular mode and in a VoIP mode, the method comprising;
the cellular system receiving a call originating from a phone registered with the cellular system, wherein the call is associated with a destination number identifying a destination for the call;
the cellular system obtaining a forwarding number associated with the VoIP system;
storing the destination number; and
forwarding the call to the forwarding number to establish a connection between the cellular system and the VoIP system, such that the VoIP system can be used to connect the call with the destination.

Abstract
Embodiments of the invention provide novel solutions, including systems, methods and/or software, for providing handoffs between cellular providers and VoIP providers. In some cases, for example, upon the initiation of a call from a dual-mode cellular phone, the cellular network (and/or a component thereof) may be configured to store the dialed number and/or substitute a predetermined number for the dialed number. The predetermined number may be associated with a VoIP provider'"'"'s system. Hence, in a particular embodiment, the call may be routed (e.g., via the PSTN) to the VoIP provider'"'"'s system, which may be configured to obtain (perhaps from an application server) the original dialed number and/or to route the call (e.g., via the PSTN) to the original dialed number. If the dual-mode phone subsequently obtains IP access, a VoIP connection may be established between the VoIP system and the phone and/or a handoff may be performed (e.g., in the VoIP system) to transfer the call from the cellular connection to the VoIP connection. Optionally, the cellular connection may be terminated.
