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.
