Abstract

Disclosed is a method of controlling a terminal. Context information related to a location of the terminal is acquired, and the location of the terminal is determined by comparing acquired context information and patterns information representing a target location previously set. At least one of transmission power and a scan period for communication between the terminal and another terminal is determined according to characteristics of the determined location.

Claims

1. A method of controlling a terminal, the method comprising:

acquiring context information related to a location of the terminal;

determining the location of the terminal by comparing acquired context information and patterns information related to a target location previously set; and

determining at least one of transmission power and a scan period for communication between the terminal and another terminal according to characteristics of the determined location.

2. The method of claim 1, wherein the target location previously set is inside a vehicle, and

wherein determining the location of the terminal comprises determining a type of the vehicle based on the context information.

3. The method of claim 2, wherein determining at least one of the transmission power and the scan period comprises:

decreasing the transmission power, by the terminal, when the terminal is located inside the vehicle, the transmission power and increasing the scan period, by the terminal, when the terminal is located outside the vehicle.

4. The method of claim 2, wherein determining at least one of the transmission power and the scan period comprises:

stopping a scan operation of searching for another terminal when a communication channel is established between the other terminal and the terminal, and the other terminal and the terminal are inside the vehicle.

5. The method of claim 2, wherein determining at least one of the transmission power and the scan period comprises:

changing a magnitude of the transmission power based on an internal distance of the vehicle, where the internal distance depends on the determined type of the vehicle.

6. The method of claim 1, wherein the location of the terminal is determined based on whether the terminal communicates with the other terminal present at the target location previously set, and

wherein the other device transmits power to the terminal.

7. The method of claim 1, further comprising:

generating the patterns information based on previous context information that the terminal previously acquired at the previously set target location.

8. The method of claim 1, further comprising:

transmitting, to the other terminal, information related to a determined one of the transmission power and the scan period.

9. The method of claim 1, further comprising:

changing the transmission power and the scan period when the location of the terminal determined based on acquired context information in a predetermined period changes.

10. A terminal comprising:

a context information acquirer that acquires context information related to a location of the terminal;

a position determiner that determines the location of the terminal by comparing acquired context information and patterns information related to a target location previously set; and

a controller that determines at least one of transmission power and a scan period for communication between the terminal and another terminal according to characteristics of the determined location.

11. The terminal of claim 10, wherein the target location previously set is inside a vehicle, and

wherein the position determiner further determines a type of the vehicle based on the context information.

12. The terminal of claim 11, wherein, when the terminal is located inside the vehicle, the controller further decreases the transmission power and increases the scan period, in comparison to when the terminal is located outside the vehicle.

13. The terminal of claim 11, wherein, when a communication channel is established between the other terminal and the terminal, and the other terminal and the terminal are both inside the vehicle, the controller further stops a scan operation of searching for another terminal.

14. The terminal of claim 11, wherein the controller further changes a magnitude of the transmission power based on an internal distance of the vehicle, where the internal distance depends on the determined type of the vehicle.

15. The terminal of claim 10, wherein the position determiner further determines the location of the terminal based on whether the terminal communicates with the other terminal at the target location previously set, and

wherein the other device transmits power to the terminal.

16. The terminal of claim 10, wherein the controller further generates the patterns information based on previous context information that the terminal previously acquired at the previously set target location.

17. The terminal of claim 10, further comprising:

a communicator that transmits, to the other terminal, information related to a determined one of the transmission power and the scan period.

18. The terminal of claim 10, wherein the controller further changes the transmission power and the scan period when the location of the terminal determined based on acquired context information in a predetermined period changes.

19. A non-transitory computer-readable storage medium having stored therein program instructions which, when executed by a computer, perform a method of controlling a terminal, the method comprising:

acquiring context information related to a location of the terminal;

determining the location of the terminal by comparing acquired context information and patterns information related to a target location previously set; and

determining at least one of transmission power and a scan period for communication between the terminal and another terminal according to characteristics of the determined location.
