Abstract

According to an embodiment of the present disclosure, there is provided a method of allowing a mobile terminal to measure its own location. The measurement method may include receiving a temporary identifier from a neighbor terminal using near field wireless communication; transmitting a location information request to a base station using the temporary identifier when location information is required; and receiving location information from the base station. The location information may be measured by the neighbor terminal.

Claims

1. A method of allowing a mobile terminal to measure its own location, the method comprising:

receiving a temporary identifier from a neighbor terminal using near field wireless communication;

transmitting a location information request to a base station using the temporary identifier when location information is required; and

receiving location information from the base station,

wherein the location information is measured by the neighbor terminal.

2. The method of claim 1, wherein the reception of a temporary identifier using near field wireless communication uses an active RFID scheme.

3. The method of claim 1, wherein the reception of a temporary identifier using near field wireless communication uses either one of a Bluetooth scheme and a Zigbee scheme.

4. The method of claim 3, wherein the reception of a temporary identifier is implemented through a beacon message transmitted from the neighbor terminal.

5. The method of claim 3, wherein the reception of a temporary identifier is implemented by accessing the neighbor terminal at a preset time to receive a message containing the temporary identifier.

6. The method of claim 1, further comprising:

examining an effective time of the temporary identifier prior to transmitting the location information request to a base station,

wherein the effective time is received together with a temporary identifier of the neighbor terminal.

7. The method of claim 1, further comprising:

receiving a temporary identifier from the base station;

transmitting the received temporary identifier to a neighbor terminal using near field wireless communication; and

transmitting a temporary identifier of the neighbor terminal received from the neighbor terminal to the base station.

8. The method of claim 7, wherein said receiving a temporary identifier from the base station is implemented by determining a specific time.

9. The method of claim 7, wherein said receiving a temporary identifier from the base station is implemented when the mobile terminal initially accesses the base station.

10. The method of claim 7, wherein a time for transmitting a temporary identifier to a neighbor terminal is concurrently received by using a specific near field wireless communication scheme when receiving the temporary identifier from the base station.

11. The method of claim 1, wherein the temporary identifier is received from the base station after the neighbor terminal transmits its own location information to the base station.

12. A mobile terminal, comprising:

a wireless communication unit; and

a controller configured to control the wireless communication unit to transmit and/or receive a temporary identifier to and/or from a neighbor terminal, request the location information of the neighbor terminal having the temporary identifier to a base station, and receive the location information of the neighbor terminal from the base station,

wherein the transmission and reception of the temporary identifier is implemented through near field wireless communication.

13. The mobile terminal of claim 12, wherein the near field wireless communication is any one of an active RFID scheme, a Bluetooth scheme, and a Zigbee scheme.
