MAINTAINING CONNECTION BETWEEN IN CONTROL POINT AND SWITCHING POINT

摘要

A method of maintaining a connection between an intelligent network control point (SCP) and a switching point (13, 14) in a telecommunications system, and a telecommunications system comprising at least one subscriber (MS) and an intelligent network comprising service switching points (13, 14) and at least one service control point (SCP) that contains service logic programs. The method comprises the steps of providing a service connection with an identifier when a service connection is set up between an intelligent network control point (SCP) and a first switching point (13 or 14) or when the intelligent network switching point (13 or 14) used for the service connection changes, transmitting the service connection identifier and preferably the address of the control point (SCP) and the switching point (13 or 14) state data corresponding to the service connection from the old switching point (13 or 14) to the new switching point (13 or 14) whenever the subscriber (MS) moves from the area of one switching point (13 or 14) to the area of another switching point (13 or 14), and setting up a service connection from the new switching point (13 or 14) to the control point (SCP) by means of the transmitted data, whereafter the service logic program to be used, corresponding to the service connection, is identified by means of the service connection identifier.
