Abstract

The present invention is essentially a method and system for leaving and retrieving messages at specific coordinate way points within a commercial mobile radio service (CMRS) provider network. Users carry or transport interface devices for communicating over the network and are able to record and view messages at specific coordinate locations while traveling in the network. The location of the device is calculated by the device or by the network while the device is powered on and in within the physical boundaries of the network, or through a combination of both. Messages can be made available to network subscribers when their interface devices come within an area centered about a physical coordinate location. Personalized messages can also be left by subscribers at any coordinate point within the boundaries of the network. The invention can also be used to facilitate access of information about an asset when a technician comes within a physical proximity threshold relative to said asset.

Claims

1. A messaging method for use in a mobile radio service provider network associated with coordinate way points and a plurality of subscriber devices, the method comprising:

receiving a user-generated message from a subscriber device including a receiver designation within the network, wherein the received message is associated with the coordinate way point and the received message is associated with a specific area of granularity and a time period during which the received message is available;

storing the user-generated messages within the network;

determining when the subscriber devices are in range of the coordinate way point and can receive the received message based on the associated receiver designation, wherein the determining is based on a profile and a location of the subscriber device; and

sending the received message to the determined subscriber devices.

2. The messaging method according to claim 1, wherein the area of granularity is pre-set by either the network or the devices.

3. The messaging method according to claim 1, wherein the area of granularity is selectable by either the network or the devices.

4. The messaging method according to claim 1, wherein the time period is pre-set by either the network or the devices.

5. The messaging method according to claim 1, wherein the time period is selectable by either the network or the devices.

6. A messaging method comprising:

receiving a user-generated message from a first user device, the message including a receiver designation, a level of granularity around a coordinate location that the message may be made available to at least one second user device;

storing the message;

determining recipients of the stored message, wherein the determining is based on a profile, a location of the at least one second user device, and the level of granularity of the stored message;

wherein

the profile of the at least second user device includes a name and an interest of the second user,

the level of granularity includes an area surrounding the coordinate location that the message is accessible;

sending the stored message to the determined at least one second user.

7. A messaging system comprising:

a messaging server configured to communicate with a plurality of devices;

the server including

a receiver, the receiver configured to receive a user-generated message from the devices, the message including a receiver designation, a level of granularity around a coordinate location that the message may be made available to the devices;

a memory, the memory configured to store the message;

a determination module configured to determine recipients of the stored message, wherein the determining is based on a profile, a location of the devices, and the level of granularity of the stored message;

wherein

the profile of the devices include a name and an interest of a user, the level of granularity includes an area surrounding the coordinate location that the message is accessible;

a transmitter, the transmitter configured to transmit the stored message to the determined recipients.

8. The system according to claim 7 wherein said devices include personal computers, cell phones, personal digital assistants or user-supported computers.

9. The system according to claim 7 wherein a location of said devices is determined by utilizing a positioning algorithm based on a method selected from the group consisting of triangulation of multiple signals, signal strengths of multiple signals, time difference of arrival of different signals, angle of arrival differences of different signals, GPS signals, and combinations thereof.

10. The system according to claim 7 wherein the messaging server communicates with the plurality of devices over a wireless network, said network is divided up into a two-dimensional grid of grid points, said network associating a physical location of the device with one or more of said grid points.

11. The system according to claim 10 wherein said network communicates using a protocol selected from the group consisting of CDMA, TDMA, FDMA, wide-band CDMA.

12. The system according to claim 7 wherein the messaging server communicates with the plurality of devices over a wireless network, said network is divided up into a three-dimensional grid of grid points, said network associating a physical location of the devices with one or more of said grid points.

13. The system according to claim 12 wherein said network communicates using a protocol selected from the group consisting of CDMA, TDMA, FDMA, wide-band CDMA.
