Abstract

Provided is a method for performing a Bluetooth communication in a wireless terminal. The method includes steps of in a Bluetooth performance optimization mode of the wireless terminal, designating an orientation or direction in which the wireless terminal is to be positioned corresponding to a Bluetooth device to communicate with the wireless terminal; measuring and storing a received signal strength indication (RSSI) of the wireless terminal positioned in the designated orientation or direction; repeatedly performing the above steps while storing the RSSI associated with each orientation or direction in which the wireless terminal is positioned; and displaying the RSSI associated with each orientation or direction in which the wireless terminal is positioned.

Claims

1. A method for performing a Bluetooth communication in a wireless terminal, the method comprising steps of:

in a Bluetooth performance optimization mode of the wireless terminal, designating an orientation or direction in which the wireless terminal is to be positioned corresponding to a Bluetooth device to communicate with the wireless terminal;

measuring and storing a received signal strength indication (RSSI) of the wireless terminal positioned in the designated orientation or direction;

repeatedly performing the above steps while storing the RSSI associated with each orientation or direction in which the wireless terminal is positioned; and

displaying the RSSI associated with each orientation or direction in which the wireless terminal is positioned.

2. The method of claim 1, wherein the step of designating the orientation or direction comprises steps of:

in the Bluetooth performance optimization mode of the wireless terminal, setting a reference orientation or direction between the wireless terminal and the Bluetooth device; and

changing the orientation or direction of the wireless terminal from the reference orientation or direction while designating the orientation or direction in which the wireless terminal is to be positioned.

3. The method of claim 2, wherein the reference orientation or direction is set by a user, or is set automatically.

4. The method of claim 1, wherein the step of measuring and storing the RSSI comprises steps of:

measuring the RSSI of the wireless terminal positioned in the designated orientation or direction; and

storing the measured RSSI in a Bluetooth performance table correspondingly to the designated orientation or direction.

5. The method of claim 4, further comprising a step of determining whether or not the wireless terminal is positioned in the designated orientation or direction.

6. The method of claim 1, further comprising a step of, when the wireless terminal is positioned in an orientation or direction in which the RSSI is above a certain level, initiating a Bluetooth communication execution mode either automatically or by a user'"'"'s selection.

7. A method for performing a Bluetooth communication in a wireless terminal, the method comprising steps of:

in a Bluetooth performance optimization mode of the wireless terminal, sensing whether or not the wireless terminal moves around a Bluetooth device;

upon the sensing of the moving of the wireless terminal, measuring and storing the RSSI of each orientation or direction depending on the movement of the wireless terminal; and

displaying the RSSI associated with each orientation or direction depending on the moving of the wireless terminal.

8. The method of claim 7, further comprising a step of setting a reference orientation or direction between the wireless terminal and the Bluetooth device, and sensing whether or not the wireless terminal moves.

9. The method of claim 8, wherein the reference orientation or direction is set by a user or is set automatically.

10. The method of claim 7, wherein the step of measuring and storing the RSSI comprises steps of:

measuring the RSSI of each orientation or direction depending on the movement of the wireless terminal; and

storing the measured RSSI in a Bluetooth performance table correspondingly to the orientation or direction.

11. The method of claim 7, further comprising a step of, when the wireless terminal is positioned in a direction in which the RSSI is above a certain level, initiating a Bluetooth communication execution mode either automatically or by a user'"'"'s selection.

12. A method for performing a Bluetooth communication in a wireless terminal, the method comprising steps of:

in a Bluetooth communication execution mode of the wireless terminal, measuring an RSSI with regard to signal received from a Bluetooth device that is communicating with the wireless terminal;

determining whether or not the measured RSSI is lower than at least one previously stored RSSI; and

when the measured RSSI is less than the at least one previously stored RSSI, informing that the measured RSSI is low.

13. The method of claim 12, wherein the at least one previously stored RSSI is stored in a Bluetooth performance table, wherein the Bluetooth performance table stores an RSSI associated with each of a plurality of orientations or directions in which the wireless terminal is positioned corresponding to the Bluetooth device.

14. The method of claim 12, further comprising a step of, when the measured RSSI is greater than the at least one of the previously stored RSSIs, measuring the RSSI at each of a plurality of periods.

15. The method of claim 12, wherein any one of the wireless terminal and the Bluetooth device informs that the RSSI is low.

16. The method of claim 12, further comprising a step of, after informing that the RSSI is low, informing of the orientation or direction in which an RSSI is greater than the measured RSSI.

17. A computer-readable medium having embodied thereon a computer program for executing a method for performing a Bluetooth communication in a wireless terminal, the method comprising:

in a Bluetooth performance optimization mode of the wireless terminal, designating an orientation or direction in which the wireless terminal is to be positioned corresponding to a Bluetooth device to communicate with the wireless terminal;

measuring and storing a received signal strength indication (RSSI) of the wireless terminal positioned in the designated orientation or direction;

repeatedly performing the above steps while storing the RSSI associated with each orientation or direction in which the wireless terminal is positioned; and

displaying the RSSI associated with each orientation or direction in which the wireless terminal is positioned.

18. A computer-readable medium having embodied thereon a computer program for executing a method for performing a Bluetooth communication in a wireless terminal, the method comprising:

in a Bluetooth performance optimization mode of the wireless terminal, sensing whether or not the wireless terminal moves around a Bluetooth device;

upon the sensing of the moving of the wireless terminal, measuring and storing the RSSI of each orientation or direction depending on the movement of the wireless terminal; and

displaying the RSSI associated with each orientation or direction depending on the moving of the wireless terminal.

19. A computer-readable medium having embodied thereon a computer program for executing a method for performing a Bluetooth communication in a wireless terminal, the method comprising:

in a Bluetooth communication execution mode of the wireless terminal, measuring an RSSI with regard to signal received from a Bluetooth device that is communicating with the wireless terminal;

determining whether or not the measured RSSI is lower than at least one previously stored RSSI; and

when the measured RSSI is less than the at least one previously stored RSSI, informing that the measured RSSI is low.
