ABSTRACT:
A system for location of communication end users including a plurality of wide area networks which control the transmission of voice, data, file and other types of messages in a preconfigured exchange area, each area network including a plurality of local servicing offices controlled by a central regional service point wherein the local servicing offices track, monitor and receive user specific information from users within their designated area and which respond to search requests from the regional service points, the regional service points providing an interface to other wide area networks for complete global communication and location of communication end users. The local servicing offices and regional service points are computer based systems controlled by microprocessors and having databases for permanently and temporarily storing predetermined end user information and messages from and intended for selected end users, whereby the local servicing offices and regional service points communicate with each other and with other wide area networks via a physical communication network which provides communication links between the networks and the end users whether wireless or wired.
