Abstract
An interface between a public switched telephone network (PSTN), a wireless communication network having a plurality of cells and a plurality of mobile switching centers (MSCs), and a wireless device. The interface includes a broadband telecommunications network. It also includes an integrated services hub (ISH). The ISH is communicatively coupled to the wireless device and the broadband network. The ISH receives RF communications from the wireless device and converts the RF communications into control and data signals usable by said broadband network. The ISH has an antenna with a first coverage area extending over a pico cell. The interface also comprises a service manager communicatively coupled to the broadband network, to the wireless network, and to the PSTN. The service manager receives the control and data signals from the ISH via the broadband network and forms and provides signaling communications in response to receiving the control and data signals. The signaling communications control the operation of switches in the PSTN. The service manager communicates with selected ones of the plurality of MSCs in the wireless network to perform hand-offs of the wireless device from the first coverage area to a selected one of the plurality of cells within the wireless network.
