Dynamic and current information is provided regarding a wireless device's
entry into or exit from a geographically defined "watched" area. An area
watcher application monitors preconfigured wireless devices entry/exit
into preconfigured watched areas. The watched areas may watch for any/all
subscribers, or for select, preconfigured subscribers listed in an
appropriate table or database. Provision of location information is
triggered by a wireless subscriber's entry, exit or changing between
designated `watched` areas or locations. Continuous polling may be used,
or the mobile device itself or network element may be triggered to push
its own location upon notification of its entry into or out of watched
areas from an area watcher. A third party may be notified when a wireless
user enters an area surrounding their retail store, and be sent a message
such as "sale inside", or "Your rentals are overdue", on their wireless
device.
