Abstract

Provided are a presence information providing apparatus and method including an information requiring unit receiving identification information stored in a Radio Frequency Identification (RFID) tag located in a communication region of an RFID reader from the RFID reader belonging to a subscriber, and acquiring a subscriber'"'"'s presence information based on the identification information; and an information providing unit providing the subscriber'"'"'s presence information acquired by the information acquiring unit when a request for an authorized subscriber'"'"'s information is received.

Claims

1. A presence information providing apparatus comprising:

an information requiring unit receiving identification information stored in an RFID (Radio Frequency Identification) tag from the RFID reader belonging to a subscriber, and acquiring a subscriber'"'"'s presence information based on the identification information; and

an information providing unit providing the subscriber'"'"'s presence information acquired by the information acquiring unit when a request for an authorized subscriber'"'"'s information is received.

2. The presence information providing apparatus of claim 1, wherein the RFID tag is distributed to a communication device, and the identification information stored in the RFID tag further includes a communication device number.

3. The presence information providing apparatus of claim 1, wherein the RFID tag is distributed to a location, and the identification information stored in the RFID tag further includes representative location information.

4. A presence information providing method comprising:

receiving identification information stored in an RFID tag from the RFID reader belonging to a subscriber, and acquiring a subscriber'"'"'s presence information based on the identification information; and

providing the subscriber'"'"'s presence information acquired by the information acquiring unit when a request for an authorized subscriber'"'"'s information is received.

5. The presence information providing method of claim 4, wherein the RFID tag is distributed to a communication device, and the identification information stored in the RFID tag further includes a communication device number.

6. The presence information providing method of claim 4, wherein the RFID tag is distributed to a location, and the identification information stored in the RFID tag further includes representative location information.

7. A presence information providing system comprising:

an RFID host receiving identification information stored in an RFID tag from the RFID reader belonging to a subscriber, and acquiring a subscriber'"'"'s presence information based on the identification information; and

an open service gateway providing the subscriber'"'"'s presence information acquired by the RFID host when a request for an authorized subscriber'"'"'s information is received.
