Abstract: A method, system, and apparatus, including a program encoded on computer-readable medium, for routing communications to a mobile device includes registering a cellular telephone identifier with a visitor location register associated with a bridge mobile switching center adapted to receive communication through a cellular backbone network and route communications over a packet-switched network and determining that cellular communications using the cellular telephone identifier are disabled. A home location register associated with the cellular telephone is notified that the cellular telephone is roaming in a network served by the visitor location register. A communication directed to the cellular telephone is received at the bridge mobile switching center. The received communication is routed to the cellular telephone.

Abstract: A system for verifying an association between an application and a mobile computing device. The application is identified by an application instance identifier, which uniquely identifies the instance of the application on the mobile computing device. The system receives a request to verify the application, including the application instance identifier. The system also obtains a mobile device identifier used to communicate with the mobile computing device. The system initiates one or more telephone call setup messages, which signal a voice call request, to the mobile computing device using the mobile device identifier. Based on receiving an indication that the one or more telephone call setup messages were detected at the mobile computing device, the system associates the application instance identifier with the mobile device identifier.

Abstract: A system for verifying an association between an application and a mobile computing device. The mobile computing device transmits a request to a service to verify the application, which has an application instance identifier. A mobile device identifier, used to establish a communication channel with the mobile computing device, is also conveyed to the service. The mobile computing device receives one or more telephone call setup messages directed to the mobile device identifier, each of which signal a voice call request, and provides an indication to the service of the receipt of the telephone call setup messages. In response to receiving the indication, the service establishes an association between the application instance identifier and the mobile device identifier.
