DISTRIBUTED CONNECTION CONTROL IN TELECOMMUNICATION NETWORKS

摘要

The invention relates to a method for handling connection in a telecommunication system comprising digital, computer controlled telephone exchanges and subscribers connected thereto, wherein the connection handling is distributed out in the network. Physical connections between subscribers are handled under control of abstract connection models, wherein in an object oriented system a number of different, mutually independent user processes are provided in such a manner that one or more of said processes under control of one or more processors control that or those connections which are necessary to achieve e.g. reservation of a connection path, connection set up, through-connection and release of a complete connection, and re-direction of connections. The invention solves the problem to coordinate a number of processes by means of a set of functional objects which allow each user to control and change a connection without coordination with other users. The method is called connection model and supports the setting up of connections in a communication network. The connection models comprise port objects representing connection end ports and connection objects representing abstract connections between end ports. When objects and models have been linked togheter in a chain, the connection can be physically set up via a connection set up function.
