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

In a system for optimizing a route of a telecommunication connection to be set up between a calling subscriber and a called subscriber iD a telecommunication system that includes a mobile switching center, a service control point, a service switching point connected to the service control point, and a subscriber register, and wherein the telecommunication connection to be set up is directed to the service control point via the service switching point, the improvement comprising:

• a gateway connected to the service control point and to the subscriber register, said gateway comprising:
• means for handling a database query, a signaling query, a database query response and a signaling query response;
• means for receiving a database query from said service control point;
• means for changing said database query to said signaling query;
• means for sending said signaling query to said subscriber register;
• means for receiving a signaling query response from said subscriber register;
• means for changing said signaling query response to said database query response;
• and
• means for sending said data query response to said service control point.

A method comprising:

• receiving, at a gateway, a database query from a service control point;
• converting, at the gateway, the database query received from the service control point into a signaling query;
• sending, from the gateway, the signaling query to a subscriber register;
• receiving, at the gateway, a signaling query response from the subscriber register comprising routing information in a first format;
• converting, at the gateway, the signaling query response comprising routing information in the first format into a database query response comprising the routing information in a second format;
• and
• sending, from the gateway, the database query response comprising the routing information in the second format to the service control point,
• wherein, in response to receiving the database query response, the service control point determines an optimal route to a mobile switching center serving the called terminal based on the database query response comprising routing information in the second format, and directs a service switching point to conduct routing for connection setup to the mobile switching center serving the called terminal.

A system comprising:

• a service control point;
• a service switching point;
• a subscriber register;
• and
• a gateway configured to:
• receive a database query from the service control point;
• convert the database query received from the service control point into a signaling query;
• send the signaling query to the subscriber register;
• receive, from the subscriber register, a response to the signaling query, the response comprising routing information in a first format;
• convert the received response comprising routing information in the first format into a database query response comprising the routing information in a second format;
• and
• send the database query response comprising the routing information in the second format to the service control point,
• wherein, in response to receiving the database query response, the service control point is configured to determine an optimal route to a mobile switching center serving the called terminal based on the database query response comprising the routing information in the second format, and direct the service switching point to conduct routing for connection setup to the mobile switching center serving the called terminal.
