Prior to the detailed description of the present invention, a brief description will be given of Bluetooth.

First, Bluetooth aims to communicate within a range of 10m, and this range can be up to 100m depending on the output.

In addition, according to the standard, the maximum data transmission speed of Bluetooth can be up to 1Mbps, but it is generally possible up to 64Kbps for synchronous (voice) channel transmission and up to 723.2Kbps for asynchronous (data) channel transmission. The transmission speed of 1Mbps is due to the relatively easy and low-cost transmission rate using the 2.4GHz Industrial Scientific Medical (ISM) frequency band.

In addition, the frequency hopping spread spectrum technique adopted in Bluetooth has improved security compared to the existing wireless communication protocol. Bluetooth is significantly lower in power consumption than the conventional short-range wireless data communication protocol because it is widely applied to portable or mobile devices due to the nature of Bluetooth. Such a characteristic of Bluetooth is a great advantage.

In addition, Bluetooth employs a CVSD (Continuous Variable Slope Delta) modulation scheme, which can be used not only for transmission of character data but also for voice transmission. In addition, a cryptographic technique is used to maintain communication secrets. In addition, the biggest feature of Bluetooth is its ability to communicate with other information communication equipments in a bag or pocket with a shielding permeability.

The concept of Bluetooth according to the embodiment of the present invention and the concept of Bluetooth used in the present invention have been outlined above. Hereinafter, a system according to an embodiment of the present invention and its detailed operation will be described. First, the system of the present invention will be described with reference to FIG.

FIG. 1 is a schematic view of a system including a portable terminal and a Bluetooth headset according to an embodiment of the present invention. Referring to FIG.

Referring to FIG. 1, the system to which the present invention is applied includes a portable terminal 100 and a Bluetooth headset 200. At this time, the portable terminal 100 and the Bluetooth headset 200 are provided with a Bluetooth module for supporting Bluetooth communication and satisfy the Bluetooth Headset Profile.

Before describing the operation of the present invention, the concept defined in the Bluetooth headset profile will be briefly described.

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

Here, the audio gateway AG is a device that acts as an audio gateway for input and output. For example, the mobile terminal 100 as shown in FIG. 1, a personal computer (PC), a notebook computer, and the like may be included. Also, the headset HS may represent a device that performs the 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.

Meanwhile, among the devices having the built-in Bluetooth module, communication can be performed between the portable terminal 100 serving as the audio gateway AG and the Bluetooth headset 200 serving as the headset HS using the Bluetooth headset profile . At this time, when communication is performed using the Bluetooth headset profile, an AT command that is basically provided is defined on the portable terminal 100 side and the Bluetooth headset (HS) 200 side, Respectively.

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

Based on Table 1, the newly defined AT command format to be presented through the present invention will be described as follows.

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

2 is a diagram illustrating a command transmission / reception relationship for battery level notification of a Bluetooth headset according to an 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. In other words, FIG. 2 shows a flow of data transmission / reception using an AT command extended and defined according to the present invention.

Referring to FIGS. 1 and 2, the portable terminal 100 and the Bluetooth headset 200 can connect Bluetooth communication by a general pairing procedure (operation 201). Next, when the Bluetooth headset 200 is paired with the portable terminal 100, the Bluetooth headset 200 can extract its battery level and transmit it to the portable terminal 100 (step 203). At this time, the Bluetooth headset 200 can transmit the Bluetooth level through the AT command defined in advance to the portable terminal 100. [ That is, the Bluetooth headset 200 may check its battery level in response to the pairing and transmit the promised command corresponding to the battery level to the portable terminal. For example, the Bluetooth headset 200 can transmit the 'AT + XX1' message to the mobile terminal 100 using the extended AT command of the present invention.

An example of the extended AT command used in the present invention is shown in Table 2 below.

As shown in Table 2, '+ XX0' to '+ XX5' represent AT command extensions of the AT command defined in the present invention for transmitting and receiving commands related to the Bluetooth level. The extension of the AT command may be defined as a value preset between the portable terminal 100 and the Bluetooth headset 200. The form of the extended AT command of the present invention shown in Table 2 is an example shown in order to facilitate understanding of the present invention and is not necessarily limited to the above embodiment. Also, depending on the battery level display method, the numerical data representing the battery level can be provided in different forms, which can be displayed in proportion to the battery capacity.

Next, upon receiving 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. The portable 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 according to a predetermined method (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, tactile output through the vibration unit, or a combination thereof. Such an output method will be described later, and a detailed description thereof will be omitted here.

When the portable terminal 100 requests the Bluetooth headset 200 to execute a specific function in step 207, the portable terminal 100 transmits the Bluetooth command to the Bluetooth headset 200 through the AT command defined in advance in the Bluetooth headset 200, Level (step 209). For example, the portable terminal 100 can transmit the 'AT + XX0' message 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 it to the portable terminal 100 (step 211). At this time, the battery level transmission of the Bluetooth headset 200 may be a battery level to check at the time of receiving the battery level request. Accordingly, the Bluetooth headset 200 maps to a reference value set in consideration of an error range of a battery level to be checked at the corresponding point in time, and thereby the response is made by any one of the commands shown in Table 2 can do.

Next, upon receiving the AT command, the portable terminal 100 may transmit a response message corresponding to the AT command to the Bluetooth headset 200. [ In step 213, the portable terminal 100 analyzes the received Bluetooth level and outputs information on the battery level of the Bluetooth headset 200 according to a predetermined method.

Next, the portable terminal 100 and the Bluetooth headset 200 may perform a corresponding function by Bluetooth communication in response to a user request (step 215). The corresponding function may include voice signal communication transmitted by voice communication of the portable terminal 100, audio signal communication transmitted by reproducing the music file of the portable terminal 100, and the like.

Meanwhile, the Bluetooth headset 200 may periodically check its own battery level while performing Bluetooth communication with the mobile terminal 100. At this time, if the Bluetooth headset 200 detects that the battery level of the Bluetooth headset 200 is lowered to a low level equal to or lower than a preset threshold value in step 217, the current Bluetooth level may be transmitted to the portable terminal 100 in step 219. For example, the Bluetooth headset 200 may transmit the 'AT + XX5' message to the portable terminal 100 using the extended AT command of the present invention.

Upon receiving the AT command, the portable terminal 100 can transmit a response message corresponding to the AT command to the Bluetooth headset 200. [ In step 221, the portable terminal 100 analyzes the received Bluetooth level and outputs information on the battery level of the Bluetooth headset 200 according to a set method.

At this time, if the battery level of the Bluetooth headset 200 is lower than a predetermined threshold value, the portable terminal 100 may generate an alarm alarm according to the set method and perform the corresponding operation in step 223. For example, the audio signal of the alarm set in the Bluetooth headset 200 may be transmitted to alarm the alarm by the Bluetooth headset 200 or may be transmitted to the portable terminal 100 ) Can be alarmed.

When the battery level is lower than the preset threshold value, the portable terminal 100 changes the audio signal output path set in the Bluetooth headset 200 to the speaker of the portable terminal 100 Can be performed. Then, the portable terminal 100 can output an audio signal through its own speaker.

2, the portable terminal 100 may perform Bluetooth communication with the Bluetooth headset 200 at a predetermined time interval (for example, 2 minutes, 5 minutes, 10 minutes, etc.) It is also possible to transmit a command requesting the battery level of the headset 200 to thereby periodically acquire and output the battery level of the Bluetooth headset 200. [

Although not shown in FIG. 2, the portable terminal 100 waits for a predetermined time for a response message from the Bluetooth headset 200 after requesting the battery level as described above. At this time, if there is no response message from the Bluetooth headset 200 within the predetermined time, the command for requesting the battery level may be retransmitted.

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