Location dependent non-commercial messaging

A method for forwarding location dependent messages from a first user's mobile device to a second user's mobile device in accordance with a proximity based messaging protocol, the method comprising:

• performing a confirmation procedure by a plurality of users including at least the first and second users to allow the plurality of users to link their phone numbers with other users, thereby establishing a network of pre-approved linked users,
• transmitting a location dependent message from a first user to a central server,
• periodically monitoring from the central server, the geographic location of the first user and the geographic location of at least one other user from a predefined messaging group defined by the first user, and
• delivering the location dependent short text message from the central server to the at least one other user after determining that the second user's geographic location is within a pre-defined geographic proximity of the first user in accordance with the periodic monitoring.

A system for forwarding location dependent messages from a first user's mobile device to a second user's mobile device, the system comprising:

• a plurality of mobile devices operable in a communication network, each device configured to permit determination of its geographic location, wherein the plurality of mobile devices are linked with each other in an established network of pre-approved linked users,
• a central server configured to receive location dependent short text messages transmitted from each of said plurality of mobile devices in said network, said central server being further configured to transmit validated location dependent short text messages to intended recipient mobile devices in accordance with a message transmission protocol,
• a central server managing entity for managing functions associated with said central server, said functions comprising:
• validating the location dependent short text messages received at the central server, wherein validation comprises validating the geographic location specified in the location dependent short text messages received at the central server,
• polling the geographic locations of at least one of said plurality of mobile devices in said network to determine if an intended recipient mobile device user has entered a geographic location specified in a location dependent short text message received at said central server, and
• transmitting validated location dependent short text messages to intended recipient mobile device users.

A method for forwarding location dependent messages from a first user's mobile device to a second user's mobile device, the method comprising:

• performing a confirmation procedure by a plurality of users including at least the first and second users to allow the plurality of users to link their phone numbers with other users, thereby establishing a network of pre-approved linked users,
• selecting, by the first user, the second user from among a plurality of users as an intended recipient of a location dependent message,
• selecting, by the first user, a prescribed region defined as a prescribed distance from a geographic location defining a pre-condition for transmitting the location dependent message to the second user,
• transmitting the location dependent message from the first user to a central server,
• periodically monitoring from the central server, a current geographic location of the second user to determine if the second user enters within the prescribed region selected by the first user, and
• transmitting the location dependent short text message from the central server to the second user after determining that the second user has entered within the prescribed region as determined by the periodic monitoring.

A method of communicating between a message sender and a message recipient via a third party, comprising:

• said message sender and message recipient performing a confirmation procedure to allow the message sender and message recipient to link their phone numbers with each other and with other users, thereby establishing a network of pre-approved linked users,
• said message sender identifying said message recipient operating a mobile cellular communication device;
• said message sender identifying a geographic location;
• said message sender creating a message for said message recipient to receive when said recipient is in said geographic location;
• and
• said message sender transmitting said message intended for said message recipient to a third-party for automated delivery to the communication device of said message recipient when said third party determines that said message recipient is in said geographic location.
