Abstract

An apparatus and a method for providing a goods information service in a mobile terminal are provided. The apparatus includes a goods information storage, a position determiner, and a controller. The goods information storage receives and stores tag information collected by an RFID reader. The position determiner determines position information of relevant goods using tag information corresponding to goods information among tag information already stored. When receiving a position information request, the controller processes to determine goods information included in the request and determine the position information of the relevant goods.

Claims

1. An apparatus for providing goods information at an information collector, the apparatus comprising:

a goods information storage for receiving and storing tag information collected by a Radio Frequency IDentification (RFID) reader;

a position determiner for determining position information of relevant goods using tag information corresponding to goods information among tag information already stored; and

a controller for, when receiving a position information request, processing to determine goods information included in the request and determine the position information of the relevant goods.

2. The apparatus of claim 1, further comprising:

a communication unit for transmitting the determined position information of the relevant goods to a mobile terminal.

3. The apparatus of claim 2, wherein the communication unit transmits a tag information request to the RFID reader and receives tag information from the RFID reader.

4. The apparatus of claim 1, wherein the position determiner determines the position information of the relevant goods using a distance between the RFID reader and an RFID tag that provides the tag information.

5. The apparatus of claim 4, wherein the position determiner determines position information of the RFID reader that has recognized tag information using the tag information corresponding to the goods information included in the request, and determines the position information of the relevant goods using the position information of the RFID reader.

6. The apparatus of claim 5, wherein the position determiner determines the position information of the relevant goods using at least one of a Time of Arrival (ToA) method using a signal transmission time between the RFID reader and the RFID tag, a Time Difference of Arrival (TDoA) method using a difference in a distance that is a signal delivery time difference between the RFID reader and the RFID tag, and a method that estimates a point where an antenna direction that is a coverage area of RFID readers and a signal source meet as a position of the relevant goods.

7. The apparatus of claim 6, wherein the mobile terminal outputs the position information received from the information collector comprising the position of the relevant goods.

8. The apparatus of claim 1, wherein the RFID reader that collects the tag information comprises a plurality of RFID readers to doubly receive tag information corresponding to a plurality of goods.

9. A method for providing goods information at an information collector, the method comprising:

receiving and storing tag information collected by a Radio Frequency IDentification (RFID) reader;

when receiving a position information request, determining goods information included in the request; and

determining position information of relevant goods using tag information corresponding to goods information among tag information already stored.

10. The method of claim 9, further comprising:

transmitting the determined position information to a mobile terminal.

11. The method of claim 9, wherein the determining of the position information of the relevant goods comprises using a distance between the RFID reader and an RFID tag that provides the tag information.

12. The method of claim 11, wherein the determining of the position information of the relevant goods further comprises:

obtaining the tag information corresponding to the goods included in the request;

determining position information of the RFID reader that has recognized the tag information using the obtained tag information; and

determining the position information of the relevant goods using the position information of the RFID reader.

13. The method of claim 12, wherein the determining of the position information of the relevant goods further comprises using at least one of a Time of Arrival (ToA) method using a signal transmission time between the RFID reader and the RFID tag, a Time Difference of Arrival (TDoA) method using a difference in a distance that is a signal delivery time difference between the RFID reader and the RFID tag, and a method that estimates a point where an antenna direction that is a coverage area of RFID readers and a signal source meet as a position of the relevant goods.

14. The method of claim 13, wherein the mobile terminal outputs the position information received from the information collector comprising the position of the relevant goods.

15. The method of claim 9, wherein the RFID reader that collects the tag information comprises a plurality of RFID readers to doubly receive tag information corresponding to a plurality of goods.
