In addition, if the user presses the call button again during the call, the call is terminated. The call sound control button is a button for the user to adjust the volume of the call during the call. The above buttons are also used as a function to end the alarm transmission of the Bluetooth headset.

4 is a block diagram of a Bluetooth module 12 and 16 according to an embodiment of the present invention.

Referring to FIG. 4, a controller 406 controls the overall operation of the Bluetooth module and processes HCI packets transmitted and received through host interface units 206 and 310.

5 is a flowchart illustrating a procedure for transmitting a packet indicating an alarm occurrence to a Bluetooth headset in a mobile communication terminal according to an exemplary embodiment of the present invention.

Referring to FIG. 5, first, in step 501, the controller 200 checks whether an alarm is set by a user's operation. The user sets the alarm by entering the time, melody and interval. When the alarm setting is detected, the control unit 200 checks the time in step 503 and checks whether the alarm time set by the user is reached in step 505. If it is not the alarm time, the controller 200 returns to step 503 to check the time again, and if it is the alarm time, the controller 200 proceeds to step 507 to play the melody set by the user. Send out through). For example, the controller 200 reads music data about a melody set by a user from the memory 206 and transmits the music data to the melody chip 212, and the melody chip 212 converts the music data into an audible analog signal. The conversion is output to the speaker 216.

After transmitting the alarm (melody) as described above, the control unit 200 applies an operation clock (eg, 19.68MHz) to the Bluetooth module 12 in step 507. That is, the Bluetooth module 12 is operated. In operation 511, the controller 200 generates a command for instructing an alarm. This command is communicated to the Bluetooth module 12 via the HCI interface. That is, the controller 200 transmits a command for instructing the alarm to the Bluetooth module 16 of the Bluetooth headset device through the Bluetooth module 12 in step 513. For example, the packet including the command may be transmitted through an Asynchronous Connection-Less (ACL) link connected between the Bluetooth module 12 and the Bluetooth module 16.

After transmitting the command instructing the alarm, the controller 200 checks whether a response is received from the Bluetooth headset device in step 515. If the response is not received, the controller 200 checks whether the command transmission frequency reaches a predetermined number in step 527. If the predetermined number of times has not been reached, the controller 200 returns to step 513 to perform the following steps again to transmit the command to the headset device again. If the predetermined number of times is reached, the control unit 200 proceeds to step 529, displays an error message on the display unit 210 of the terminal, and then proceeds to step 517.

On the other hand, when the response is received, the controller 200 checks whether the alarm release button of the mobile communication terminal is input by the user's operation in step 517. When the alarm cancel button is input, the controller 200 proceeds to step 521. When the alarm cancel button is not input, the controller 200 proceeds to step 519 to check whether a predetermined time has elapsed.

If the predetermined time has not elapsed, the control unit 200 returns to step 517 to check the alarm cancellation again. If the predetermined time has elapsed, the control unit 200 proceeds to step 521.

If the alarm release button is input or a predetermined time has elapsed after the alarm transmission, the controller 200 stops transmitting the alarm (melody) of the mobile communication terminal in step 521 and ends.                     

6 illustrates a procedure for receiving and processing a command for instructing an alarm from a mobile communication terminal in a Bluetooth headset device according to an embodiment of the present invention.

Referring to FIG. 6, the controller 300 first checks whether a packet is received through the Bluetooth module 16 in step 601. The packet received by the Bluetooth module 16 is delivered to the control unit 300 through an HCI interface, and the control unit 300 determines whether a packet is received by checking data input through the HCI interface. If the packet is not received, the controller 300 proceeds to step 619 to perform a corresponding mode. Upon reception of the packet, the controller 300 proceeds to step 603 to analyze the received packet.

In operation 605, the controller 300 determines whether the packet indicates an alarm. If it is not the alarm instruction, the controller 300 proceeds to step 621 and performs a corresponding process corresponding to the received packet. If the packet indicates an alarm, the controller 300 controls the Bluetooth module 16 to transmit a response packet to the received packet to the Bluetooth module 12 of the mobile communication terminal in step 607. In addition, the control unit 300 transmits the alarm data set in advance to the codec 320 in step 609 to transmit the alarm to the outside. At this time, the output of the speaker is controlled and the alarm is sent out at a size enough to be recognized by the user (about 85 dB). In other words, a headset that supports both a receiver and a speaker is used.

During the alarm transmission, the control unit 300 checks whether the alarm release button of the headset device is input by a user's key operation in step 611. When the alarm cancel button is input, the controller 300 immediately proceeds to step 615, and when the alarm cancel button is not input, the controller 300 proceeds to step 613 and checks whether a predetermined time has elapsed.

If the predetermined time has not elapsed, the control unit 300 returns to step 611 again to check for alarm cancellation, and if the predetermined time has elapsed, the control unit 230 proceeds to step 615.

If the alarm release button is input or a predetermined time has elapsed after the alarm transmission, the controller 300 stops transmitting the alarm (melody) of the headset device in step 615 and ends.

Here, there are two methods for releasing the alarm of the Bluetooth headset, firstly, as described above with reference to FIG. 6, the alarm may be terminated by the alarm release button of the headset itself, and second, the user may press a button (alarm stop command) of the mobile communication terminal. By transmitting the alarm button, the mobile communication terminal may send an alarm stop command to the headset to terminate the alarm of the headset.

On the other hand, the second method, the user to operate the button of the mobile communication terminal to release the alarm, the mobile communication terminal device by sending an alarm stop command to the headset device to cancel the alarm of the headset device. However, since two-way communication between Bluetooth devices is possible, a user may release an alarm by operating a button of the headset device, and the headset device may release an alarm of the mobile communication terminal by sending an alarm stop command to the mobile communication terminal.                     

In addition, a snooze function may be implemented by intervals between the alarm occurrence time of the mobile communication terminal and the alarm occurrence time of the headset device according to the user's setting. If the melody chip is implemented in the Bluetooth headset device, the mobile communication terminal may transmit the MIDI (MIDI) data instead of the alarm command command to play the data in the headset device.

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the scope of the following claims, but also by those equivalent to the scope of the claims.

As described above, in the present invention, since the Bluetooth headset device acts as a separate alarm clock, it is possible to eliminate the trouble of purchasing a separate alarm clock or setting an alarm of the alarm clock. In other words, it is possible to obtain a double alarm clock effect in a single operation of setting an alarm in the terminal, and to implement a snooze function, so that the utilization is very large.
