Location dependent non-commercial messaging

Abstract

A system and method is disclosed for forwarding location dependent messages from a message sender's mobile cellular device to an intended recipient's mobile cellular device. The method is principally practiced in a communication network comprising a plurality of mobile cellular devices having location determining capabilities such as triangulation and GPS. In an embodiment, the message sender identifies an intended message recipient and selects a geographic location and corresponding radius of circumference defining geographic pre-conditions for transmitting the location dependent message to the intended message recipient. The message is first transmitted to a central server which periodically monitors the geographic location of the intended recipient in real time or near real-time to determine if the intended recipient enters within the radius of circumference of the geographic location selected by the message sender. The message is transmitted from the central server when it is determined that the intended recipient has satisfied the geographic pre-conditions. In other embodiments, a cellular mobile device user is alerted when one or more contacts of the user arrives within a certain geographic proximity of the user.
