A pager includes a global positioning system receiver so that the pager may be interrogated by a remote requester for the user's current location. The information can be provided to the requester in response to a request made over the Internet. The requester can be queried for authentication information before providing the information. In this way, the positioning information may be obtained automatically without requiring any action on the part of the pager owner.

1. A pager comprising:a global positioning system receiver; a transceiver coupled to said receiver to transmit global positioning coordinates of the receiver, said transceiver being operable to automatically transmit said coordinates when a request for the coordinates is received; an event generator coupled to said transceiver, said event generator to track the global positioning coordinates of said receiver such that when said tracked global positioning coordinates deviate from a set of preprogrammed coordinates said deviated coordinates are automatically transmitted by said transceiver; a power down device that transitions said pager into a sleep mode when a battery is low, said pager periodically awakening from said sleep mode to automatically transmit said global positioning coordinates of said receiver; and a user selectable panic operator, such that once the operator is operated, said transceiver automatically sends a message indicating that help is needed and including the coordinates of the global positioning system receiver.
