Abstract

A presence service providing system and method is disclosed that provides presence information regarding presentities to watchers. The presence system sets mapping information, which contains the presence information that matches position information corresponding to at least one presentity. When the position information is received via a positioning system, the presence system detects the presence information, which matches the received position information, from the set mapping information. The detected presence information is transmitted from the presence system to a watcher. The presence service providing system can provide a variety of presence information according to the location of the presentity, so that watchers can more specifically and clearly identify the states of the presentity from the presence information.

Claims

1. A method for updating presence information of a terminal by a presence server, comprising:

receiving presence information from the terminal, wherein the presence information comprises communication intention data being determined based on whether or not a staying time of the terminal is greater than or equal to a preset time interval, wherein the preset time interval is determined based on a location of the terminal, and wherein the communication intention data indicates whether communication is possible or not;

storing the received presence information;

updating the stored presence information if the presence information is different from previously stored presence information; and

providing the presence information of the terminal to another terminal that requests the presence information of the terminal.

2. The method of claim 1, wherein the presence information is received through a positioning system or from the terminal.

3. The method of claim 1, wherein the presence information is received periodically.

4. The method of claim 1, wherein the presence information contains identification data that is individually allocated to the terminal and coordinate data indicating position coordinates of the terminal.

5. A method for updating presence information of a terminal by the terminal, the method comprising:

transmitting presence information to a presence server, wherein the presence information comprises communication intention data being determined based on whether or not a staying time of the terminal is greater than or equal to a preset time interval, wherein the preset time interval is determined based on a location of the terminal and wherein the communication intention data indicates whether communication is possible or not;

determining whether the presence information is changed by movement of the terminal; and

transmitting the changed presence information if the presence information is changed.

6. The method of claim 5, wherein the presence information is transmitted through a positioning system to the presence server.

7. The method of claim 6, wherein the presence information is transmitted periodically.

8. The method of claim 5, wherein the presence information contains identification data that is individually allocated to the terminal and coordinate data indicating position coordinates of the terminal.

9. A presence server, comprising:

a transceiver configured to transmit and receive signals; and

a controller configured to;

receive presence information from a terminal, wherein the presence information comprises communication intention data being determined based on whether or not a staying time of the terminal is greater than or equal to a preset time interval, wherein the preset time interval is determined based on a location of the terminal, and wherein the communication intention data indicates whether communication is possible or not;

store the received presence information;

update the stored presence information if the presence information is different from previously stored presence information; and

provide the presence information of the terminal to another terminal that requests the presence information of the terminal.

10. The presence server of claim 9, wherein the presence information is received through a positioning system or from the terminal.

11. The presence server of claim 9, wherein the presence information is received periodically.

12. The presence server of claim 9, wherein the presence information contains identification data that is individually allocated to the terminal and coordinate data indicating position coordinates of the terminal.

13. A terminal, comprising:

a transceiver configured to transmit and receive signals; and

a controller configured to;

transmit presence information to a presence server, wherein the presence information comprises communication intention data being determined based on whether or not a staying time of the terminal is greater than or equal to a preset time interval, wherein the preset time interval is determined based on a location of the terminal, and wherein the communication intention data indicates whether communication is possible or not;

determine whether the presence information is changed by movement of the terminal; and

transmit the changed presence information if the presence information is changed.

14. The terminal of claim 13, wherein the presence information is transmitted through a positioning system to the presence server.

15. The terminal of claim 13, wherein the presence information is transmitted periodically.

16. The terminal of claim 13, wherein the presence information contains identification data that is individually allocated to the terminal and coordinate data indicating position coordinates of the terminal.
