Abstract
A method and apparatus for controlling a cellular mobile telecommunication system. A switch and a telecommunication control complex cooperate to set up connection between a telecommunication network, such as the common carrier public telephone network, and a plurality of mobile units. The switch sets up connections between trunks to the telephone network and communication links connected to the cell sites of the mobile telecommunication system. The telecommunication control complex, including a mobile telecommunication controller and the cell site controllers, controls the radio connections between these communication links and the mobile units.
