Abstract:
1. A method of communicating voice within a converged networking operating environment wherein a gateway is deployed in a service provider's telecommunications network and client software is embedded in a target device that is operable within both the telecommunications network and a second network to which the target device is connectable, the service provider's telecommunications network having a set of one or more network elements that comprise or are associated with a voice over IP infrastructure, and a home location register (HLR) to which a subscriber's identity is assigned, and wherein a connection is established between the client software and the gateway, the subscriber having a mobile telephone number, the method comprising: detecting presence of the target device in the second network; upon detecting presence of the target device, updating given information in the HLR to identify the gateway as a location of the target device when the target device is connected to the second network, wherein after updating the given information in the HLR the gateway acts as a visitor location register (VLR); routing voice calls received to the mobile telephone number over the voice over IP infrastructure to the target device without using a number or identity associated with the second network; and routing voice calls initiated by the target device over the voice over IP infrastructure, wherein the initiated voice calls appear as if originating from the mobile telephone number instead of a number or identity associated with the second network.
