Communication system
First Claim
1. Communication system including a switching system which comprises a switching unit and a control circuit, wherein said control circuit comprises:
- a transmitting-side signalling handler procedure (ASH) means for managing a connection and for exchanging messages with other procedures, anda receiving-side signalling handler procedure (BSH) means for managing a connection and for exchanging messages with other procedures, wherein said switching unit is coupled to a service control system, said control circuit further comprises an additional procedure (ZUSA) means for exclusively exchanging messages with the transmitting-side and the receiving-side signalling handler procedure means (ASH, BSH), and, when certain messages occur, the additional procedure (ZUSA) means receives and sends messages by a service program (SERV) of the service control system and, in dependence on the messages produced by the service program (SERV), sends messages to the transmitting-side and/or receiving-side signalling handler procedure means (ASH, BSH), and wherein the additional procedure (ZUSA) means comprises both a transmitting-side and a receiving-side state procedure(NA, NB) means for detecting a state of the transmitting-side and receiving-side signalling handler procedure means (ASH, BSH) on the basis of the messages which the additional procedure (ZUSA) means receives.

Abstract
A communication system including a switching system which comprises a switching unit and a control circuit. The control circuit comprises a transmitting-side signalling handler procedure (ASH) for managing the connection and for exchanging messages with other procedures, and a receiving-side signalling handler procedure (BSH) for managing the connection and for exchanging messages with other procedures. For providing optional external services, the switching unit is coupled to a service control system. Furthermore, the control circuit comprises an additional procedure (ZUSA) for exclusively exchanging messages with the transmitting-side and the receiving-side signalling handler procedures (ASH, BSH). For specific messages, the additional procedure (ZUSA) is provided for exchanging messages by a service program (SERV) of the service control system and, dependent upon the messages produced by the service program (SERV), provided for sending messages to the transmitting-side and/or receiving-side signalling handler procedures (ASH, BSH).
