Abstract

Provided are an apparatus and method for providing position information, and a user terminal and method for outputting position information. The apparatus for providing position information includes a first position information calculator configured to calculate first position information of mobile object using at least three signals received from at least three signal transmission devices, a second position information calculator configured to calculate second position information of the mobile object by mapping the calculated first position information of the mobile object to information on the mobile object'"'"'s surroundings, and a position information transmitter configured to transmit the calculated second position information of the mobile object to a terminal.

Claims

1. An apparatus for providing position information of mobile object, comprising:

a first position information calculator configured to calculate first position information of the mobile object using at least three signals received from at least three signal transmission devices;

a second position information calculator configured to calculate second position information of the mobile object by mapping the calculated first position information of the mobile object to zone information on the mobile object'"'"'s surroundings; and

a position information transmitter configured to transmit the calculated second position information of the mobile object to a terminal.

2. The apparatus of claim 1, further comprising a zone information storage configured to store the zone information on the mobile object'"'"'s surroundings.

3. The apparatus of claim 2, further comprising a surrounding geographic information recognizer configured to collect and provide the zone information on the mobile object'"'"'s surroundings to the zone information storage.

4. The apparatus of claim 1, wherein the first position information calculator calculates distances between the mobile object and the respective signal transmission devices using times at which the at least three signals are received, and calculates the first position information of the mobile object using the calculated distances.

5. The apparatus of claim 1, wherein the zone information on the mobile object'"'"'s surroundings includes an identification number of a space in which the mobile object is located, and

the second position information includes an identification number of a space corresponding to the first position information.

6. The apparatus of claim 1, wherein the position information transmitter transmits the second position information to the terminal using one communication method among Bluetooth, Zigbee, infrared data association (IrDA), wireless fidelity (WiFi) and wireless personal area network (WPAN).

7. The apparatus of claim 1, wherein the mobile object is a vehicle used for transporting passengers or cargo.

8. The apparatus of claim 1, wherein the signals are navigation signals or radio signals including position information on the signal transmission devices.

9. A method of providing position information of mobile object performed by a position information providing apparatus, comprising:

calculating first position information of the mobile object using at least three signals received from at least three signal transmission devices;

calculating second position information of the mobile object by mapping the calculated first position information of the mobile object to zone information on the mobile object'"'"'s surroundings; and

transmitting the calculated second position information of the mobile object to a terminal.

10. The method of claim 9, wherein the calculating of the first position information includes:

calculating distances between the mobile object and the respective signal transmission devices using times at which the at least three signals are received; and

calculating the first position information of the mobile object using the calculated distances.

11. The method of claim 9, wherein the zone information on the mobile object'"'"'s surroundings includes an identification number of a space in which the mobile object is located, and

the second position information includes an identification number of a space corresponding to the first position information.

12. A user terminal, comprising:

a position information receiver configured to receive a signal including position information on a zone in which a mobile object is located;

a distance measurer configured to measure a distance between the user terminal and the mobile object on the basis of the received position information of the mobile object;

a determiner configured to determine whether the mobile object is within a predetermined range of the user terminal on the basis of the measured distance; and

a notifier configured to output a notification sound indicating that the mobile object is within the predetermined range according to the determination result.

13. The user terminal of claim 12, wherein the position information on the zone in which the mobile object is located includes an identification number of a space in which the mobile object is located.

14. A method of outputting position information performed by a user terminal, comprising:

receiving a signal including position information on a zone in which a mobile object is located;

measuring a distance between the user terminal and the mobile object on the basis of the received position information of mobile object;

determining whether the mobile object is within a predetermined range of the user terminal on the basis of the measured distance; and

outputting a notification sound indicating that the mobile object is within the predetermined range according to the determination result.
