The Software Structure of the Call Control for ATM Systems

摘要

In this paper, we are going to introduce the software structure of the call control function for ATM(Asynchronous Transfer Mode) systems.rnThere are many systems to be developed for ATM Networks which have call control function. So it is valuable to design the software structure of the call control function to have reusability and portability. And ATM signalling capability is dynamically evolving to have multi-party, multi-connection and negotiation of connections, etc., it is important for the structure to have expandability to further signalling capability.rnTo achieve this goal, we have separated the call control function into call control entity and signalling protocol entities. And we adopted object-oriented design and programming to develop these entities. The software structure and the classes defined for call control function will be explained.
