Geographical call routing for a non-emergency calling service
First Claim
1. A service switching point (SSP) servicing telephone calls based on a location of a calling party, said SSP comprising:
- a trigger that causes said SSP to forward call information to a service control point when the SSP recognizes a call to an abbreviated telephone number, the call information including a telephone number of the calling party and SSP information; and
a router that receives a specific routing telephone number from the service control point and routes the call to the specific routing telephone number, wherein the specific routing telephone number from the service control point is based on the SSP information when the SSP is not a split SSP, and is based on both location information of the calling party and the SSP information when the SSP is a split SSP.

Abstract
A communications system is provided for routing calls based on a location of a calling party. The communications system includes a processor that determines routing of a call placed by a calling party using one of a plurality of call origination devices. The call origination devices are operatively connected to a switching device that is operatively connected to the processor. The call is placed to a destination corresponding to a service having a service area. The switching device services calls placed from call origination devices located within the service area and calls placed from call origination devices located outside the service area. The processor determines whether the calling party is within the service area, and the processor instructs the switching device to route the call to the destination based upon the processor determining that the calling party is within the service area. The switching device routes the call to the destination only when the processor determines that the calling party is within the service area.
