Dynamically Updated Proximity Warning
First Claim
1. A method for alerting the user of a mobile device of the proximity of a target party, comprising:
- receiving an electronic location information message corresponding to the target party, said electronic location information message including target location data;
responsive to the electronic location information message, determining a target location estimate based on the target location data;
comparing the target location estimate to a bounded region surrounding a current position estimate for the mobile device; and
selectively generating an alert at the mobile device based on the proximity of the target location estimate to the bounded region.

Abstract
Methods and apparatus are disclosed for alerting a mobile device user of the proximity of a target party. In an exemplary method, an electronic location information message corresponding to the target party is received, the electronic location information message including target location data. In response to the receipt of the location information message, a target location estimate is determined, based on the target location data. The target location estimate is compared to a bounded region surrounding a current position estimate for the mobile device, and an alert is selectively generated based on the proximity of the target location estimate to the bounded region. An application processor, configured to implement one or more methods for alerting the user of a mobile device of the proximity of a target party, is also disclosed. Various embodiments of the disclosed application processor may be used in an application server operatively connected to the mobile device through a communications network, or in the mobile device itself.
