MOBILE COMMUNICATIONS FROM COMPUTER AIDED DISPATCH SYSTEM VIA A CUSTOMER PREMISES GATEWAY FOR SATELLITE COMMUNICATION SYSTEM

A mobile satellite system includes a satellite communication switching office having a satellite antenna for providing communication of satellite messages via a satellite. The mobile satellite system also includes a mobile communication system transmitting to and receiving messages from the mobile satellite system, and a computer aided dispatch (CAD) system sending to and receiving customer messages from the mobile communication system via the mobile satellite system. A central controller controls communication in the mobile satellite system. A customer premises gateway (CPG) system provides an interface between the CAD system and the central controller, enabling the mobile communication system to transmit the messages to the CAD system and enabling the CAD system to transmit the customer messages to the mobile communication system.
