Abstract

A location provision facility communicates with a mobile telecommunications device over an IP-based telecommunications network to obtain information that enables the facility to determine a location of the telecommunications device. The facility and/or the telecommunications device store the determined location. In response to requests from location-based applications for the location of the telecommunications device, the facility can provide the location-based applications with the stored or calculated location.
