Location ID service for telephone calls
First Claim
1. A method of providing location information of a calling device to a called device, comprising:
- receiving into a signal switching point a call trigger emanating from the calling device;
generating a query from the signal switching point to a signal transfer point, the query containing an identifier of the calling device;
delivering the query from the signal transfer point to a signal control point;
accessing location information associated with the identifier of the calling device from a database linked to the signal control point;
delivering the location information from the signal control point to the signal switching point through the signal transfer point; and
providing the location information from the signal switching point to the called device.

Abstract
A system for providing location ID services for telephone calls transfers location data describing the location of the calling device to the called device. Rather than or in addition to providing the name and telephone number as is done through the conventional caller ID service, the location of the calling device is displayed by the called device including the zip code, the longitude and latitude planar coordinates, or the street address. Existing advanced intelligent network infrastructure may be adapted to provide the location ID service, such as by providing location data queries from a signal switching point to a signal control point. The signal control point has access to a CNAM database containing location ID data fields in addition to conventional caller ID data.

16. A system for providing location information of a calling device to a called device, comprising:
-
a first signal switching point configured to receive a call trigger emanating from the calling device and transmit the call trigger and an identifier of the calling device;
a second signal switching point configured to receive the call trigger and identifier of the calling device transmitted from the first signal switching point, produce a query for location information where the query contains the identifier of the calling device, and provide the location information to the called device;
a database containing location information indexed by identifiers of calling devices;
a signal control point configured to access location information from the database upon receipt of the query for location information; and
a signal transfer point configured to deliver the query from the signal switching point to the signal control point and deliver the location information from the signal control point to the signal switching point.
