As a result of the determination in step S401, if a wired communication link is formed by wire, the DSP 137 proceeds to step S409.

On the contrary, if the wired communication link is not formed, the DSP 137 proceeds to step S403 and recognizes that the Bluetooth communication link is formed. If the DSP 137 detects that the Bluetooth communication link is formed with the mobile terminal 100 in step S403, the DSP 137 receives the caller number information of the received call from the mobile terminal 100 in step S405. In step S407, the DSP 137 controls the second Bluetooth module 131 to transmit a reception request signal for caller name information corresponding to the received caller number information. At this time, the DSP 137 transmits the reception request signal for the caller name information using the PBAP included in the second Bluetooth module 131. Thereafter, the DSP 137 proceeds to step S409.

Subsequently, in step S409, the DSP 137 determines whether the information on the caller received from the mobile terminal 100 is name information. If the name information is name information, the DSP 137 proceeds to step S413 and activates the alarm unit 139.

On the contrary, if not the name information, the DSP 137 proceeds to step S411 to recognize the caller's number information and proceeds to step S413, and activates the alarm unit 139.

Subsequently, in step S415, the DSP 137 controls the alarm unit 139 activated in step S413 to output the caller's name information or call information. In this case, the output of the information may be voice data. Subsequently, when the DSP 137 receives a signal for transmitting a call function request signal for a call received from the input unit (not shown) to the mobile terminal 100 in step S417, the DSP 137 receives the call function request signal. To transmit to the mobile terminal (100).

Thereafter, in step S419, the DSP 137 detects that the call function authorization signal is received from the mobile terminal 100, and in step S421, the DSP 137 performs the call function. At this time, the DSP 137 outputs the voice signal received from the second Bluetooth module 131 to the speaker SPK and controls the audio processor 141 to convert the voice signal into an electrical voice signal by the microphone MIC.

In this case, a detailed description of the power charging will be described with reference to FIGS. 6 to 7.

When charging the headset 200 in step S505, the mobile terminal 100 determines whether the headset 200 is registered. As a result of the determination, if the registered state, the mobile terminal 100 proceeds to step S523, and if not registered, the portable terminal 100 proceeds to step S507 and transmits a registration information request signal to the headset 200.

The headset 200 transmits the registration information to the mobile terminal in response to the registration information request signal in step S509. In this case, the registration information may be a unique number and an authentication number stored in the second Bluetooth module 131.

Subsequently, in step S511, the mobile terminal 100 determines whether the headset 200 is a headset capable of Bluetooth registration based on the registration information. If the headset 200 is a registered headset 200, the mobile terminal 100 determines the headset 200 in step S517. Complete the registration. Thereafter, in step S519, the mobile terminal 100 transmits a registration completion signal indicating that the registration is completed to the headset 200, and in step S521, the headset 200 receives the registration completion signal and the mobile terminal 100. Outputs completion of Bluetooth registration.

On the contrary, if the headset 200 is not registered, the mobile terminal 100 transmits a signal indicating that registration is impossible to the headset 200 in step S513. In operation S515, the headset 200 outputs a signal indicating that registration is impossible. In this case, the signal output may be output as voice data, vibration or beep sound.

Subsequently, in step S523, the mobile terminal 100 enters the authentication number change mode of the headset 200. In step S525, the mobile terminal 100 changes the authentication number by inputting the authentication number of the headset 200 to be changed by the mobile terminal 100. . Thereafter, the mobile terminal 100 transmits the authentication number of the changed headset 200 to the headset 200 in step S527. Subsequently, in step S529, the headset 200 receives the changed authentication number, and in step S531, the headset 200 changes and stores an existing authentication number with the authentication number. The headset 200 transmits the change completion signal of the authentication number to the mobile terminal 100 in step S533, and the mobile terminal 100 matches the unique number of the headset 200 according to the completion signal in step S535. The authentication number is stored in the second Bluetooth module 131.

Thereafter, the mobile terminal 100 performs the corresponding function in step S537. In this case, the corresponding function may be a communication with the headset 200 in which the wired communication link is formed, or may be an independent communication or additional function of the mobile terminal 100.

At this time, the headset 200 may be supplied with power from the mobile terminal 100 and charged while registering for Bluetooth communication via a wired communication link or changing the authentication number of the headset 200. In addition, the registration mode may mean a mode for pairing (Paring) during the procedure for performing the Bluetooth communication between the mobile terminal 100 and the headset 200. Accordingly, in order to perform Bluetooth communication registration through a wired communication link, the mobile terminal 100 and the headset 200 may include a kind of protocol according to wired communication that may be involved in the Bluetooth communication.

Referring to FIG. 6, when it is determined in step S601 that the wired communication link is formed by wired connection with the headset 200, the control unit 115 proceeds to step S605. On the contrary, if it is determined that the wired communication link is not established, the controller 115 detects that the headset 200 is connected to the headset 200 through Bluetooth communication in step S603 and proceeds to step S605.

In step S605, the controller 115 compares the power remaining amount of the headset 200 received by the second Bluetooth module 131 with an arbitrary threshold value in step S607 according to the formed communication link. In this case, if the remaining amount of power is greater than the threshold, the controller 115 proceeds to step S617 to display the remaining amount of power.

On the contrary, if the remaining amount of power is smaller than the threshold value, in step S609 the control unit 115 is so that the power of the mobile terminal 100 is applied to the headset 200 through the port unit 119 or the first Bluetooth module 117. Control the power supply 121.

Subsequently, when the control unit 115 receives a signal for completing power supply from the headset 200 in step S611, the control unit 115 indicates that power supply is completed in step S613. Thereafter, the controller 115 controls the power supply unit 121 to end the power supply to the headset 200.

In this case, if the signal received by the controller 115 in step S611 is not a signal for completing power supply, the controller 115 returns to step S605 and repeats the above process.

Referring to FIG. 7, when it is determined in step S701 that the DSP 137 is wired to the portable terminal 100 to establish a wired communication link, the process proceeds to step S705. On the contrary, if it is determined that the wired communication link is not formed, the DSP 137 proceeds to step S703 and detects that it is connected by Bluetooth communication and proceeds to step S705.

In step S705, the DSP 137 controls the connector unit 133 or the second Bluetooth module 131 to transmit the remaining power remaining amount of the power charging unit 135 to the mobile terminal 100.

If the DSP 137 detects the power supply from the mobile terminal 100 in step S707, the DSP 137 controls the power charging unit 135 to charge the power in step S709. Thereafter, when the DSP 137 determines that the power charging is completed in step S711, the DSP 137 indicates that power supply is completed in step S713. On the contrary, if it is determined in step S711 that the power charging is not completed, the DSP 137 returns to step S705 to repeat the above process.
