System and method for routing a call to an optimal location
View Patent ↗The present invention is a system and method for routing a call using the GIS technologies. The method comprises the following steps: First, a call intended for a subscriber of the optimal location call routing service is received at an SSP. Second, a query is launched to an SCP for call routing instruction. Third, the SCP consults a system that is based on the GIS technology to determine the telephone number of the optimal location. Fourth, the database provides the telephone number of the optimal location for the SCP to complete the call. Communication between the SCP and the GIS system are via an application over the TCP/IP protocol. An apparatus for implementing the method is also described.
1. A method for routing a call from a calling party to a called party comprising:
receiving the call intended for the called party at a service switching point;
querying a service control point for instructions to route the call;
providing X-Y coordinates of the calling party to a GIS system;
obtaining a menu of choices with an associated list of forwarding telephone numbers of the called party from the GIS system, wherein the forwarding telephone number is found by the GIS system based on the X-Y coordinates of the calling party and is provided to the service control point;
presenting the calling party with the menu of choices from the GIS system through the service control point;
receiving from the calling party a selection based on the menu of choices;
providing the selection to the service control point;
sending based on the selection a call routing instruction from the service control point to the service switch point; and
routing the call based on the call routing instruction to a location associated with the forwarding telephone number associated with the selection.
2. The method of claim 1 , wherein the location is an optimal location based on criteria set by the called party.
3. The method of claim 2 , wherein the optimal location is a location that is physically closest to the calling party.
4. The method of claim 2 , wherein the optimal location is a location that has the least travel time from the calling party.
5. The method of claim 1 , wherein the location is an optimal location based on the selection received from the calling party.
