A system that allows wireless devices, such as mobile phones (105), pagers or PDAs, equipped with short haul radio in addition to normal cellular or PCS frequencies to register, originate and receive calls through a computer network or the Internet. Short haul radio systems may use Bluetooth or HomeRF protocols. When the wireless device comes within range of an edge device (108) in the short haul network, the wireless device detects the presence of the edge device and switches to the frequencies used by the short haul system. The edge device converts signals from the short haul radio to a format compatible with the computer network. An application processor (112) on the computer network interfaces with the wireless network's signaling and control network to allow the mobile to register on the wireless network. Incoming calls to the mobile are then under the control of the application processor, which causes calls to be routed to the edge device through an associated gateway (113). Outgoing calls are routed through the edge device to the gateway into the PSTN (101). |
