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.
