Abstract:
A method of maintaining a connection between an intelligent network control point and a switching point in a telecommunications system comprising at least one subscriber and an intelligent network comprising service switching points and at least one service control point that contains service logic programs, the method comprising:providing a service connection with an identifier when a service connection is set up between an intelligent network control point and a first switching point or when the intelligent network switching point used in the service connection changes; transmitting the service connection identifier and preferably the address of the control point and the state data of the switching point corresponding to the service connection from the old switching point to the new switching point whenever the subscriber moves from the area of one switching point to the area of another switching point; setting up a service connection by means of the transmitted data from the new switching point to the control point, whereafter the service logic program to be used, corresponding to the service connection, is identified by means of the service connection identifier; wherein the telecommunication system is a packet network and the intelligent network switching point is a support node of a packet network; and wherein the state data corresponding to the service connection contains instructions for reporting the data from the switching point to the control point and information gathered in the switching point to be reported to the control point.
