Method and apparatus for updating and providing presence information based on position information
First Claim
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.

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.

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. - View Dependent Claims (6, 7, 8)
