Procedure and system for the transmission of information and establishment of a telecommunication connection

Abstract

Procedure and system for optimizing the route of a telecommunication connection to be set up in a telecommunication system that includes a mobile switching center (MSC), a service switching point (SSP), a service control point (SCP), a gateway (GW), and a subscriber register (HLR). The service switching point is connected to the service control point and the gateway is connected to the service control point and to the subscriber register. The telecommunication connection to be set up is directed via the service switching point to the service control point. A database query is sent from the service control point, via the gateway, to the subscriber register. In response, the subscriber register returns routing information, on the basis of which an optimal route to the mobile switching center under which the B-subscriber is currently located is determined.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]The present application is a reissue application of U.S. Pat. No. 6,628,951 which claims priority to PCT Application PCT / FI1998 / 001010 filed Dec. 21, 1998, and Finnish Application No. FI974590 filed Dec. 22, 1997.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to telecommunication technology and, more particularly, the invention is directed to optimization of the route of a telecommunication connection that is set up in a mobile communication network.[0004]2. Description of Related Art[0005]For a teleoperator, i.e. an owner or operator of a telecommunications network, it is important that telecommunication connections be set up in an optimal manner. Optimization may for example be based on the length of the route of the connection or on the network load resulting from the connection. Because the traffic in mobile communication networks is continuously increasing, it is particularly important t...

AI Technical Summary

Benefits of technology

This approach optimizes the routing of telecommunication connections by ensuring calls are directed through the shortest route to the appropriate mobile switching center, reducing network load and allowing for the utilization of additional GSM network services without requiring changes to existing network elements.

Problems solved by technology

The primary problem with the above-described routing procedure is that calls addressed to mobile stations are not automatically routed via the shortest route to the proper mobile switching center but may, instead, be routed via several switching centers.

Such solutions, however, disadvantageously they bind the service to a certain base and assume that the service control point or service node is provided with an MAP interface.
