Abstract
A combination mobile station and cordless wireline cordless base station, each having a different directory number, includes a mobile station that functions in a wireless network as a typical wireless unit. When the mobile station is within radio range of the wireline cordless base station, it retunes its operating frequency to that of the wireline cordless base station. The wireline cordless base station, when it senses that the mobile station is within radio range, notifies the wireless network of the wireline directory number of the wireline cordless base station. When the wireless network receives a call for the mobile station, it forwards the call to the wireline cordless base station over the wireline network. When the mobile station is moved out of radio range of the cordless wireline cordless base station, the mobile station returns to the operating frequency of the wireless network, and the wireline cordless base station informs the wireless network that it is no longer receiving calls for that mobile station.
