Abstract

A portable terminal having a Bluetooth module and a Bluetooth communication method between the portable terminal and a device having a Bluetooth module are provided. The method includes determining whether the portable terminal receives a signal from the device in a call history viewing mode, during Bluetooth communication between the portable terminal and the device, wherein the signal is generated as a volume control key of the device is operated. The method also includes scrolling and displaying the call history, in the portable terminal, according to the received signal. The call history can be searched for in the portable terminal by using a volume control key of a headset or a hands-free accessory, which is linked to the portable terminal via Bluetooth communication, thereby providing users with a convenient mode of operation.

Claims

1. A Bluetooth communication method between a portable terminal and a device, the method comprising:

determining whether the portable terminal receives a signal from the device in a call history viewing mode, during Bluetooth communication between the portable terminal and the device; and

scrolling and displaying the call history in the portable terminal according to the received signal.

2. The method of claim 1, wherein the signal is generated as a volume control key of the device is operated.

3. The method of claim 2, wherein the scrolling and displaying of the call history comprises:

transmitting a sound volume variation value, generated as the volume control key is operated up or down, from the device to the portable terminal; and

scrolling and displaying the call history up or down in the portable terminal according to the received sound volume variation value.

4. The method of claim 3, further comprising:

transmitting a sound volume compensating value, corresponding to the received sound volume variation value, from the portable terminal to the device; and

maintaining a current volume of the device according to the received sound volume compensating value.

5. The method of claim 2, wherein the scrolling and displaying of the call history comprises:

transmitting an audio signal of the displayed call history from the portable terminal to the device, when a voice output mode is set in the portable terminal.

6. The method of claim 5, further comprising outputting a voice through at least one of a headset and a hands-free accessory corresponding to the transmitted audio signal.

7. The method of claim 6, further comprising:

determining whether a volume control key is operated; and

if the volume control key is operated, scrolling up or down the call history according to the volume control key.

8. The method of claim 2, wherein the scrolling and displaying of the call history comprises calling a phone number corresponding to one of the highlighted displayed call histories when a call key is operated.

9. A portable terminal comprising:

a first Bluetooth module for communicating with a second Bluetooth module installed in a device via Bluetooth communication; and

a controller for scrolling and displaying a call history in a call history viewing mode according to a signal that corresponds to the operation of a volume control key of the device during Bluetooth communication between the portable terminal and the device.

10. The portable terminal of claim 9, wherein the controller scrolls and displays the call history up or down according to a sound volume variation value that corresponds to an up or down operation of the volume control key of the device.

11. The portable terminal of claim 10, wherein the controller transmits a sound volume compensating value, which corresponds to the received sound volume variation value, to the device.

12. The portable terminal of claim 9, wherein the controller transmits an audio signal corresponding to the displayed call history to the device when a voice output mode is set in the portable terminal.

13. The portable terminal of claim 12, wherein the controller outputs a voice through at least one of a headset and a hands-free accessory corresponding to the transmitted audio signal.

14. The portable terminal of claim 13, wherein the controller determines whether a volume control key is operated and, if the volume control key is operated, scrolls up or down the call history according to the volume control key.

15. The portable terminal of claim 9, wherein the controller calls a phone number corresponding to one of the highlighted displayed call histories when a call key is operated.
