A method of controlling connections in a telecommunication s ystem

摘要

User terminals are connected to a telecommunication system. The telecommunication system includes a control system for the control, such as set-up, release and modification, of connections between the user terminals. A large portion of functions are common for control of dynamical as well as semi-permanent connections. Control of a connection can be initiated from any of the user terminals to which the connection relates, or from other user terminals. Control data for the connections can be stored in different types of storage resources in the control system, the different types of storage resources having different degrees of reliability.
