Referring to FIG. 1, a system to which the present invention is applied includes a mobile terminal 100 and a Bluetooth headset 200. In this case, the mobile terminal 100 and the Bluetooth headset 200 include a Bluetooth module for supporting Bluetooth communication, and satisfy the Bluetooth Headset Profile.

Hereinafter, the concept defined in the Bluetooth headset profile will be briefly described before explaining the operation of the present invention.

First, the Bluetooth headset profile can be divided into two types. An audio gateway (AG) corresponding to the mobile terminal 100 of FIG. 1 and a headset corresponding to the Bluetooth headset 200 of FIG. Can be divided into (HS, Headset).

Here, the audio gateway AG is a device that acts as a gateway of audio for input and output. For example, the mobile terminal 100 as shown in FIG. 1 may include a personal computer (PC), a notebook, and the like. In addition, the headset HS may represent a device that performs a remote input / output mechanism of the audio gateway AG. That is, the Bluetooth headset 200 may represent a device that performs a remote input / output mechanism of the mobile terminal 100.

On the other hand, among devices with a built-in Bluetooth module, the mobile terminal 100 serving as the audio gateway AG and the Bluetooth headset 200 serving as the headset HS may communicate using a Bluetooth headset profile. . At this time, when communicating using the Bluetooth headset profile, the AT command (AT command) basically provided on the portable terminal 100 side and the Bluetooth headset (HS) 200 side is defined, and the database of each other Have each of them.

Hereinafter, the AT commands of the headset profile defined in the Profile of the Specification of the Bluetooth System can be expressed as shown in Table 1 below.

Based on the <Table 1>, looking at the newly defined AT command format to be presented through the present invention as follows.

For example, the extension is newly defined as '+ XXX' to enable the operation of the present invention. That is, the data transmission operation for transmitting the battery level information of the present invention is enabled. Hereinafter, an operation of transmitting battery level information of the present invention using an AT command and a battery level notification method according to the present invention will be described with reference to FIG. 2.

2 is a diagram illustrating a command transmission / reception relationship for battery level notification of a Bluetooth headset according to an exemplary embodiment of the present invention.

In particular, FIG. 2 illustrates an embodiment of a data transmission operation using an AT command in a Bluetooth headset profile according to the present invention. That is, FIG. 2 illustrates a flow of transmitting and receiving data using an AT command that is extended and defined according to the present invention.

1 and 2, first of all, the mobile terminal 100 and the Bluetooth headset 200 may connect Bluetooth communication by a general pairing procedure (step 201). Next, when the Bluetooth headset 200 is paired with the mobile terminal 100, the Bluetooth headset 200 may extract its own battery level and transmit it to the mobile terminal 100 (step 203). In this case, the Bluetooth headset 200 may transmit the Bluetooth level through a predefined AT command with the mobile terminal 100. That is, the Bluetooth headset 200 may check its battery level in response to the pairing, and transmit a promised command corresponding to the battery level to the mobile terminal. For example, the Bluetooth headset 200 may transmit a message of 'AT + XX1' to the mobile terminal 100 using the extended AT command of the present invention.

Looking at the example of the extended AT command used in the present invention can be represented as shown in Table 2 below.

As shown in Table 2, '+ XX0' to '+ XX5' represent AT command extensions defined in the present invention for transmitting and receiving commands related to Bluetooth levels. The extension of the AT command may be defined as a value promised in advance between the mobile terminal 100 and the Bluetooth headset 200. The form of the extended AT command of the present invention shown in Table 2 above is an example shown to help understanding of the present invention, and is not necessarily limited to the above form. In addition, according to the battery level display method, the numerical data indicating the battery level may be provided in another form, which may be displayed in proportion to the battery capacity.

Next, when the mobile terminal 100 receives the AT command (AT + XX1), the mobile terminal 100 may transmit a response (ACK or OK) message corresponding to the AT command (AT + XX1) to the Bluetooth headset 200. have. When the pairing is performed, the mobile terminal 100 analyzes the AT command (AT + XX1) received from the Bluetooth headset 200 and outputs information on the battery level of the Bluetooth headset 200 in a set manner. (Step 205). The output may be output by visual output through the display unit of the portable terminal 100, auditory output through the output unit and tactile output through the vibration unit, and a combination thereof. Since the output method will be described later, a detailed description thereof will be omitted.

Next, when the mobile terminal 100 is requested to execute a specific function (step 207), the mobile terminal 100 is a battery of the Bluetooth headset 200 through an AT command predefined by the Bluetooth headset 200. A level can be requested (step 209). For example, the mobile terminal 100 may transmit a message of 'AT + XX0' to the Bluetooth headset 2000 using the extended AT command of the present invention.

Then, the Bluetooth headset 200 receives the Bluetooth level request, checks its battery level in response to the Bluetooth level request, and transmits the battery level to the mobile terminal 100 (step 211). In this case, the battery level transmission of the Bluetooth headset 200 may be a battery level checked at the time of receiving the battery level request. Therefore, the Bluetooth headset 200 maps to any one reference value set in consideration of the error range of the battery level checked at the corresponding time point, and thereby responds to any one of the commands as shown in Table 2 above. can do.

Next, when the mobile terminal 100 receives the AT command, the portable terminal 100 may transmit a response message corresponding to the AT command to the Bluetooth headset 200. The mobile terminal 100 may analyze the received Bluetooth level and output information about the battery level of the Bluetooth headset 200 in a set manner (step 213).

The corresponding function may include functions such as voice signal communication delivered by voice communication of the mobile terminal 100 and audio signal communication delivered by playing a music file of the mobile terminal 100.

Meanwhile, the Bluetooth headset 200 may periodically check its battery level while performing Bluetooth communication with the mobile terminal 100. In this case, when the Bluetooth headset 200 detects that its battery level is lowered to a low level below the set threshold (step 217), the Bluetooth headset 200 may transmit the current battery level to the mobile terminal 100 (step 219). For example, the Bluetooth headset 200 may transmit a message of 'AT + XX5' to the mobile terminal 100 using the extended AT command of the present invention.

Then, when the mobile terminal 100 receives the AT command, the mobile terminal 100 may transmit a response message corresponding to the AT command to the Bluetooth headset 200. The mobile terminal 100 may analyze the received Bluetooth level and output information on the battery level of the Bluetooth headset 200 in a set manner (step 221).

In this case, when the mobile terminal 100 recognizes that the battery level of the Bluetooth headset 200 is at a low level below the set threshold value, the mobile terminal 100 may generate an alarm alarm and perform a corresponding operation according to the set method (step 223). For example, the audio signal of the alarm set by the Bluetooth headset 200 is transmitted to alarm the alarm by the Bluetooth headset 200 or the mobile terminal 100 through the audio signal and the display of the alarm in the mobile terminal 100 itself. You can alarm by).

In addition, when the mobile terminal 100 recognizes that the battery level is at a low level below the set threshold, the mobile terminal 100 changes the audio signal output path set by the Bluetooth headset 200 to the speaker of the mobile terminal 100 itself. Can be performed. Thereafter, the mobile terminal 100 may output an audio signal through the speaker of its own.

In addition, although omitted in FIG. 2, the mobile terminal 100 performs a Bluetooth communication with the Bluetooth headset 200 at a predetermined time interval (for example, 2 minutes, 5 minutes, 10 minutes, etc.) during Bluetooth communication. A command for requesting the battery level of the headset 200 may be transmitted, and thus, the battery level of the Bluetooth headset 200 may be periodically obtained and output.

In addition, although omitted in FIG. 2, the mobile terminal 100 waits for a predetermined time for a response message from the Bluetooth headset 200 after the battery level request. In this case, when there is no response message within the predetermined time from the Bluetooth headset 200, the command for requesting the battery level may be retransmitted.

Meanwhile, as described above, the command transmission between the mobile terminal 100 and the Bluetooth headset 200 of the present invention may be performed through an asynchronous connection less (ACL) link.

In the above, the overall operation performed between the mobile terminal 100 and the Bluetooth headset 200 according to an embodiment of the present invention has been described with reference to FIGS. 1 and 2. Next, a detailed operation and a screen example for notifying the user of the battery level of the Bluetooth headset 200 in the mobile terminal 100 of the present invention will be described with reference to FIGS. 3 to 4D.
