  • Call processing system for controlling connections in a communications system
    Patent number: 5600640
    Abstract: In the development of development systems, efforts are being made to design software systems which are as modular as possible for controlling the switching system. Efforts are also being made to achieve this aim for the call processing system for controlling connections in a switching system. The basic structure of the call processing system has a signaling interface system and a call control system, both of which are limited to logic connection control and submit autonomous connection requests to a resource control system which carries out the physical connection control. The call processing system furthermore has a coordination system for coordinating the autonomous connection requests with respect to the resource control system.
