ABSTRACT:
A group of wireless device users are notified of an event. A location data determination algorithm is provided to a wireless device, where the algorithm determines a frequency at which the device interacts with network elements to determine its location. The location data is stored in a notification server and used to identify a user at a specific location. When a governmental or commercial entity wishes to issue a notification, a message is provided to those users whose location is identified as being in an area defined by the entity.
