Abstract
An improved wireless telecommunication system enables a user to obtain communication services in overlapping wireless heterogeneous or homogeneous cellular networks at the most economical cost and bandwidth. A plurality of overlapping cellular networks includes a common command channel, a Central Selection Agency (CSA), a home location register, a visitor location register, and a user device positional location mechanism. In one embodiment the user device is equipped with a Global Positioning System (GPS) to determine its location. In placing a call, the user device broadcasts its ID, location and connection capability requirements on the common command channel. When a base station for the command channel bears the request, the CSA and the home location register for the user are informed. The CSA capability/requirements determine which network and base station selections are potential carriers for the call. Based on user preferences established by a profile stored in an accessible database, the CSA assigns a network and base station to handle the connection. The user device is informed and tunes to the appropriate network and protocols. For incoming calls, the calling party checks …
