Abstract
Geographic coordinates of user equipment of a paged party are determined either by communicating with a GPS receiver associated with the user equipment of the paged party or by cellular triangulation. The geographic coordinates may be converted into an associated common location description. For example the common location description is a city name, an address, or a distance and direction from a landmark. The geographic coordinates, common location description, or an abbreviation thereof, is transmitted to user equipment of a paging party. Using this service, parents may verify the location of their children. Security agencies or delivery services may verify and/or log the location of their personnel.
