Mobile services control platform providing a converged voice service
View Patent ↗A mobile services control platform supports an enhanced service, Voice Forwarding to Wi-Fi or Wi-Fi Voice. Functionally, the service allows a subscriber to use a Wi-Fi device to receive voice calls directed to his or her mobile number. In a representative example, when the user connects over a Wi-Fi network, e.g., using his or her laptop or other such device, he or she selects “Wi-Fi Voice” option from a client. As a result, future voice calls directed to the user's mobile number get routed to his or her laptop over Wi-Fi, without the caller being aware that the user has connected over a different network. Similarly, voice calls made by the user from his or her laptop Wi-Fi (e.g., through a softphone) are delivered to the recipient's device as if they originated from the mobile phone number.
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.

9. The method as described in claim 1 wherein the subscriber's identity is a MSISDN.
10. The method as described in claim 1 further including the step of disconnecting the target device from the voice over IP infrastructure.
11. The method as described in claim 1 wherein the target device is a wireless client having a first interface to the second network and a second interface to the telecommunications network.
12. The method as described in claim 1 wherein the service provider's telecommunications network is GSM-based.
13. The method as described in claim 1 wherein the service provider's telecommunications network is CDMA-based.
14. 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 mobile subscriber's Wi-Fi device that is operable within both the telecommunications network and a wireless local area network to which the mobile Wi-Fi 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 mobile subscriber's identity is assigned, the mobile subscriber having an associated telephone number, comprising:
upon detecting presence of the mobile Wi-Fi device in the wireless local area network, updating given information in the HLR to identify the gateway as a location of the mobile Wi-Fi device when the mobile Wi-Fi device is connected to the wireless local area 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 mobile Wi-Fi device without using a number or identity associated with the wireless local area network; and
routing voice calls initiated by the mobile Wi-Fi device over the voice over IP infrastructure, wherein the initiated voice calls appear as if originating from the telephone number instead of a number or identity associated with the wireless local area network.
15. The method as described in claim 14 wherein the service provider's telecommunications network is GSM-based.
16. The method as described in claim 14 wherein the service provider's telecommunications network is CDMA-based.
