4 is a flowchart illustrating a process of performing a communication connection with a controlled terminal for performing a remote control in a portable terminal according to an embodiment of the present invention.

Referring to FIG. 4, the controller 200 of the portable terminal first checks whether a request for performing a remote control function by a user occurs in step 401. Herein, the remote control function refers to a function for controlling the controlled terminal with a voice command.

If the request to perform the remote control function does not occur, the controller 200 proceeds to step 419 to perform a corresponding function (eg, standby mode).

On the other hand, when the remote control function execution request occurs, the control unit 200 proceeds to step 403 to control the operation of the Bluetooth module 208, and proceeds to step 405 to search for a Bluetooth device capable of communication connection to the surroundings. .

After that, the controller 200 proceeds to step 407 and attempts communication connection with the Bluetooth device searched in step 405. In step 409, the controller 200 checks whether the communication connection with the surrounding Bluetooth devices is completed.

Here, the communication connection with the Bluetooth device may be performed using a general Bluetooth communication connection method, but in the present invention, it may be performed using the priority order set in FIG. 3.

That is, when the portable terminal performs a communication connection with the Bluetooth device, the portable terminal checks the previously set priority setting information and searches for a device corresponding to the order of the priority to perform the communication connection. The portable terminal does not support connection with the maximum number of connectable devices (the number defined on the BLUETOOTH SPEC).

If the communication connection is completed, the controller 200 repeats the process of step 407.

On the other hand, when the communication connection is completed, the control unit 200 proceeds to step 411 and checks whether the user senses a voice command. If the voice command is not detected, the controller 200 repeats the process of step 411 to redetect the voice command by the user.

On the other hand, when detecting the voice command, the control unit 200 proceeds to step 413 to read the detected voice command. Here, the process of reading the voice command is a process of distinguishing the type of the controlled terminal and the command for controlling the operation of the controlled terminal among the commands detected by the user.

For example, when detecting a voice command of "audio operation" from the user, the controller 200 may distinguish between "control" called "audio" and "action" which is a command for operating the audio which is the controlled terminal. Can be.

In operation 415, the controller 200 determines whether the controller 200 is connected to the device to which the command is to be transmitted, that is, the controlled terminal. If it is determined that the mobile terminal is not connected to the controlled terminal, the controller 200 proceeds to step 421 to check whether the portable terminal is connected to the maximum number of devices that can be connected. If the portable terminal is not in communication connection with the maximum number of devices that can be communicatively connected, the controller 200 repeats the process of step 405.

On the other hand, if it is confirmed that the portable terminal is in communication connection with the maximum number of devices that can communicate, the control unit 200 proceeds to step 423 to obtain previously stored priority information.

In step 425, the control unit 200 terminates the Bluetooth connection with the low priority device and repeats the process of step 405 to establish a communication connection with the controlled terminal to which the command is to be delivered. Perform.

On the other hand, if it is determined in step 415 that the connection to the controlled terminal is not connected, the controller 200 proceeds to step 413 and transmits the read command to the controlled terminal.

That is, the command “operation”, which is a command for controlling the controlled terminal, is transmitted to the controlled terminal called audio.

Thereafter, the controller 200 ends the present algorithm.

5 is a flowchart illustrating a process of performing an operation according to a command of a portable terminal in a controlled terminal according to an exemplary embodiment of the present invention.

Referring to FIG. 5, the controlled terminal first checks whether a communication connection request is received from the portable terminal in step 501. If the communication connection request is not received, the controlled terminal proceeds to step 509 to perform a corresponding function (eg, standby mode).

On the other hand, when receiving the communication connection request, the controlled terminal proceeds to step 503 to perform a communication connection with the portable terminal that performed the request, and then proceeds to step 505 to receive a command from the portable terminal. Check it. If the command is not received, the controlled terminal performs the process of step 505 again.

On the other hand, when receiving a command from the portable terminal, the controlled terminal proceeds to step 507 and performs an operation corresponding to the received command. For example, when receiving a command of "volume up" from the portable terminal, the controlled terminal processes to adjust the volume of the remote control terminal.

Thereafter, the controlled terminal ends the present algorithm.

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications may be made 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 determined not only by the scope of the following claims, but also by the equivalents of the claims.
