In particular, it can be manufactured as an accessory type device such as a necklace shape, a band shape, and a smart watch.

The wearable device 200 includes a first battery charging unit 205, a terminal voltage supplying unit 210, a second battery charging unit 215, a call mode switching unit A battery 220, a first battery 225, and a connection terminal 230.

Here, the first battery charging unit 205 according to the present invention supplies the voltage supplied by the power supply unit 300 to the first battery 225 provided in the wearable device 200. As described above, when the voltage is supplied to the wearable device 200, it is possible to perform not only the voice call but also the functions implemented in the wearable device 200 by using the voltage charged in the first battery 225.

Next, the terminal voltage supply unit 210 according to the present invention serves to supply the voltage charged in the first battery 225 to the connection terminal 230. The voltage supplied to the connection terminal 230 is a voltage required to simultaneously charge the first battery 225 of the wearable device 200 and the second battery 110 of the BT headset 100 .

The second battery charging unit 215 according to the present invention is configured to supply the voltage supplied to the connection terminal 230 to the second battery of the BT headset 100 when the wearable device 200 and the BT headset 100 are coupled, (110). At this time, the connection terminal 230 means a terminal formed on the front surface or the side surface of the wearable device 200.

The connection between the wearable device 200 and the BT headset 100 is performed through the connection terminal 230 formed on the front surface or the side surface of the wearable device 200, A voltage can be supplied to the second battery 110 of the BT headset 100. [

At this time, the coupling includes not only meaning that the BT headset 100 is fixed to the wearable device 200 but also a wider concept including an electrical engagement and data transmission / reception between the wearable device 200 and the BT headset 100.

When the BT headset 100 is disconnected from the wearable device 200, the call mode switching unit 220 detects the electrical connection of the connection terminal 230, It is responsible for switching to the BT headset call mode.

At this time, the device communication mode is performed in a state where the BT headset 100 is coupled from the wearable device 200. Although not shown, when the wearable device 200 is connected to the mobile communication system through the mobile communication network, Quot;) " in FIG. The mobile communication system has been cited as a more concept including a base station, a control station, an exchange and a mobile terminal of the other party.

On the other hand, the BT headset communication mode is a state in which the BT headset 100 is detached from the wearable device 200 and voice communication is available in the wearable device 200.

In order to make a voice call in the BT headset 100, the wearable device 200 automatically switches the voice call conversation operation to the BT headset call mode. This mode switching will be described in more detail with reference to FIG.

2 is a view showing a mode switching configuration of the wearable device 200 according to the first embodiment of the present invention.

Referring to FIG. 2, the wearable device 200 according to the first exemplary embodiment of the present invention includes a device voice sound processor 240, a Bluetooth frequency detector (not shown) to automatically switch between the device call mode and the BT headset talk mode 245 and a headset speech processing unit 250.

Here, the device call sound processing unit 240 according to the present invention emits a partner phone call sound received from a mobile terminal (not shown) of the other party in a device call mode to a speaker (not shown), receives a user call sound input by the user And transmits it to the mobile communication system via the mobile communication network.

This process is possible because it supports the voice call service in the wearable device, for example, the watch-type wearable device 200, and is therefore a further improvement over the existing wearable wearable device without the voice call function.

On the other hand, the Bluetooth frequency detecting unit 245 according to the present invention plays a role of detecting a unique Bluetooth frequency 130 of the BT headset 100 through the Bluetooth communication when changing from the device call mode to the BT headset call mode do.

At this time, the inherent Bluetooth frequency 130 of the BT headset 100 refers to a specific channel or specific frequency for interference prevention allocated to each BT headset family or model group to avoid interference between BT headsets.

Therefore, in order to detect the unique Bluetooth frequency 130, the corresponding Bluetooth frequency value may be set in the wearable device 200 in advance. In this case, even if the BT headset 100 is disconnected from the wearable device 200, the Bluetooth frequency detecting unit 245 can easily detect the Bluetooth frequency 130 inherent to the BT headset 100. When the detection is normally performed, the wearable device 200 and the BT headset 100 are in a state of being able to exchange data through Bluetooth communication.

Finally, the headset speech processor 250 according to the present invention transmits the counterpart speech received from the mobile communication system to the BT headset 100 connected via the Bluetooth communication (network).

In addition, when receiving the input user's voice through the BT headset 100, the received user's voice is transmitted to the wearable device 200 through the Bluetooth communication (network). Accordingly, the headset speech processor 250 according to the present invention receives the user's call tone from the BT headset 100 and transmits the user's call tone to the mobile communication system.

In this way, automatic switching between the device call mode and the BT headset talk mode is performed through the detachment between the BT headset 100 and the wearable device 200, and the voice call service is transmitted to the BT headset 100 and the wearable device 200). ≪ / RTI >

Meanwhile, the BT headset 100 described above charges the second battery 110 with the voltage supplied from the wearable device 200. However, the second battery 110 is designed to be small due to the BT headset 100, which is made very small so that the second battery 110 can be put on the human ear, and the charging capacity is small.

As described above, when the charging capacity to be charged in the second battery 110 is small, the BT headset 100 can not provide the voice call service for a long time. Therefore, in order to overcome this disadvantage, a means for monitoring the state of charge of the BT headset 100 was needed.

Hereinafter, the configuration of the wearable device 200 for monitoring the charged state of the BT headset 100 will be described in detail.

FIG. 3 is a block diagram showing in more detail the configuration of the wearable device 200 for pre-monitoring the state of charge of the BT headset 100 according to the first embodiment of the present invention.

Next, the time unit conversion unit 260 according to the present invention converts the voltage size detected by the voltage size determination unit 255 into a time unit (e.g., usable time) at the time of the call. The reason for converting to this time unit is that after the BT headset 100 is switched to the BT headset call mode and the voice call is made for a long time after the call connection is made in the BT headset 100, the voltage charged in the second battery 110 is consumed, It is necessary to grasp the state of charge of the second battery 110 and to switch to the device communication mode.

In other words, since the connection terminal of the BT headset 100 is inserted into the connection terminal of the wearable device 200 with the result of converting the time base unit into the charging state of the second battery 110, The wearable device 200 can perform the voice call successively.

Therefore, it is possible to continue the seamless call. At this time, if the first battery 110 of the BT headset 100 is charged to some extent, the BT headset 100 may be disconnected from the wearable device 200 to continue the seamless call. Thus, automatic switching between the BT headset call mode and the device call mode can be performed quickly, thus continuing the seamless call.

Lastly, the first usable time display unit 265 according to the present invention displays the battery usable time according to the time unit converted by the time unit conversion unit 260 described above on the display screen.

If the battery useable time is displayed on the display screen as described above, the BT headset 100 and the user of the wearable device 200 can switch the BT headset call mode and the multimedia call mode within the checked time range from time to time, It will be able to continue.

Alternatively, during the voice call through the BT headset 100, the state of the second battery 110 may be checked at any time in response to the voice call to make all the conversions. Such an example will be described with reference to FIG.

FIG. 4 is a configuration diagram illustrating a further configuration of a wearable device 200 for detecting a second battery status during a call according to the first embodiment of the present invention.

Referring to FIG. 4, the wearable device 200 according to the first embodiment of the present invention may further include a battery state conversion unit 270 and a second usable time display unit 275 for seamless communication.

The battery state conversion unit 270 according to the present invention changes the state from the device call mode to the BT headset call mode and then determines the consumption state of the second battery 110 according to the partner call tone and the user call tone.

In other words, when the user makes a communication with the other party via the BT headset 100, the battery charge state is maintained as long as the voltage charged in the second battery 110 has been communicated. At this time, the consumption state can be expressed in various forms. For example, it can be expressed as% type and battery type consumption type.

Therefore, it is necessary to connect the BT headset 100 to the wearable device 200 to switch from the BT headset call mode to the device call mode before the charged battery is exhausted, and to continue the seamless call. For this, the battery state conversion unit 270 periodically monitors the state of charge of the second battery 110 as described above.

In addition, the battery state conversion unit 270 according to the present invention converts the consumed state of the second battery 110, which has been determined in advance, into the form of a talkable time unit. This conversion is necessary to help the user more easily grasp the state of his / her second battery 110.

On the other hand, the second usable time display unit 275 according to the present invention displays the consumed state of the second battery 110 detected by the battery state conversion unit 270 or the consumed state of the second battery 110, which is determined by the battery state conversion unit 270, And displayed on the display screen.

At this time, the display screen may further display widgets (e.g., icons, input tools, and click tools) for providing a wearable device, for example, a wearable device, Of course it is.

As described above, the user frequently checks the consumed state of the second battery 110 during the call or the battery available time through the BT headset 100, thereby switching from the BT headset call mode to the device call mode, It will be able to continue.

Hereinafter, the connection structure between the wearable device 200 and the BT headset 100 will be described in detail.

If the BT headset 100 is detached from the wearable device 200 in step S140 according to the present invention, the call mode switching unit 220 detects the electrical isolation of the connection terminal of the wearable device 200. [

At this time, the electrical separation means an electrical state in which the connection between the wearable device 200 and the connection terminal of the BT headset 100 is disconnected. When such electrical separation is performed, the call mode switching unit 220 switches the device call mode to the BT headset call mode.

Hereinafter, a mode switching process between the device communication mode and the BT headset communication mode will be described in detail.

FIG. 8 is a flow chart for explaining the mode switching process of step S140 according to the second embodiment of the present invention.

As shown in FIG. 8, in step S140 according to the second embodiment of the present invention, steps S141 to S143 are performed to achieve a mode change according to a detachment state between the wearable device 200 and the BT headset 100. FIG.

First, in step S141 according to the present invention, the device call mode is switched to the device communication mode, that is, when the BT headset 100 is connected to the wearable device 200, (Not shown), and the received user's voice is received by the device call sound processing unit 2400 and transmitted to the mobile communication system via the mobile communication network.

This process is possible because it supports the voice call service in the wearable device, for example, the watch-type wearable device 200, and is therefore a further improvement over the existing wearable wearable device without the voice call function.

Thereafter, in the step S142 according to the present invention, when the BT headset 100 is disconnected from the device communication mode, that is, when the BT headset 100 is disconnected from the wearable device 200, And detects the Bluetooth frequency 130 inherent to the BT headset 100 through the Bluetooth communication.

At this time, the inherent Bluetooth frequency 130 of the BT headset 100 is set to a specific frequency for interference prevention or a specific frequency allocated to each BT headset product group or model group to avoid interference between the various types of BT headset 100, . Therefore, in order to detect the unique Bluetooth frequency 130, the corresponding Bluetooth frequency value may be set in the wearable device 200 in advance.

In this case, even if the BT headset 100 is disconnected from the wearable device 200, the Bluetooth frequency detecting unit 245 can easily detect the Bluetooth frequency 130 inherent to the BT headset 100. When the detection is normally performed, the wearable device 200 and the BT headset 100 are in a state of being able to exchange data through Bluetooth communication.

Thereafter, in step S143 according to the present invention, if the detection of step S142 is normally performed, the headset conversation processing unit 250 receives the counterpart speech signal received from the mobile communication system (not shown) or receives a user speech signal from the BT headset 100 . This means that the headset call tone processing unit 250 can freely transmit and receive a partner call sound and a user talk sound between the wearable device 200 and the BT headset 100. [

In this way, automatic switching between the device call mode and the BT headset talk mode is performed through the detachment between the BT headset 100 and the wearable device 200, and the voice call service is transmitted to the BT headset 100 and the wearable device 200).

On the other hand, if the BT headset 100 is small, the capacity of the second battery 110 mounted on the BT headset 100 also becomes small. Therefore, the BT headset 100 can not support the voice call for a long time in the BT headset call mode. To overcome this disadvantage, a process of monitoring the charging status of the BT headset 100 was required.

9 is a flowchart illustrating a process for monitoring the state of charge of the BT headset 100 in step S130 according to the second embodiment of the present invention.

Referring to FIG. 9, step S130 according to the second embodiment of the present invention may include step S131 to step S133 to monitor the state of charge of the BT headset 100.

A first connection terminal 231a formed in the first connection groove 231 of the wearable device 200 and a second connection formed in the second connection groove 232 of the wearable device 200 are formed in the wearable device 200, The connection terminals 120, 121, and 122 of the BT headset 100 are connected to one of the terminals 232a.

When the connection terminal portion 120 of the BT headset 100 is connected to the second battery 110, the second voltage supplied from the terminal voltage supplying portion 210 is supplied to the second battery 110 by the second battery charging portion 215, And the second battery 110 is charged. At this time, the connection terminal portion 120 of the BT headset 100 may be either a fixed type 122 or a push type 121 connection terminal.

In the step S132 according to the present invention, when the wearable device 200 is connected to the BT headset 100, the voltage magnitude of the voltage charged in the second battery 110 of the BT headset 100 according to the above- And the grasping unit 255 grasps it.

Thereafter, in step S133 according to the present invention, the time unit conversion unit 260 converts the voltage magnitude obtained in step S132 into a time unit at the time of talking. When converted into a time unit, the battery use time can be known.

Finally, in step S134 according to the present invention, the battery usable time corresponding to the time unit converted in step S133 is displayed on the display screen 201 of the wearable device 200 in the first usable time display unit 265 .

At this time, since the usable time displayed on the display screen 201 allows the user to know the consumption state of the second battery 110 when voice communication is performed using the BT headset 100, the consumption of the second battery 110 The BT headset 100 is immediately connected to the connection terminal 230 of the wearable device 200 before the end of the wearable device 200 so that seamless voice communication can be continued.

 FIG. 10 is a flowchart illustrating a process for monitoring a charge state according to mode switching in step S140 according to the second embodiment of the present invention.

Referring to FIG. 10, in step S140 according to the second embodiment of the present invention, steps S144 and S145 are performed to monitor the state of charge of the BT headset according to mode switching between the two models.

First, in step S144 according to the present invention, the BT headset 100 is disconnected from the wearable device 200 after changing from the device call mode to the BT headset talk mode, and the transition from the device call mode to the BT headset talk mode is quick The battery state conversion unit 270 recognizes the consumed state of the second battery 110 according to the partner telephone tone and the user's telephone tone.

In other words, when the user makes a communication with the other party via the BT headset 100, the battery charge state is maintained as long as the voltage charged in the second battery 110 has been communicated. At this time, the consumption state can be expressed in various forms. For example, it can be expressed as% type and battery type consumption type.

Accordingly, it is necessary to switch the BT headset communication mode to the device communication mode, that is, to connect the BT headset 100 to the wearable device 200 before continuing the seamless communication before the charged battery is exhausted. To this end, as described above, the battery state conversion unit 270 monitors the state of charge of the second battery 110 from time to time.

In step S144 according to the present invention, the battery state conversion unit 270 converts the consumption state of the second battery 110 identified in step S143 into a talkable time unit.

This conversion is intended to help the user more easily grasp the state of his / her second battery 110. For example, the state of the second battery 110 of the BT headset 100 is expressed in terms of talkable time units rather than the% form and the battery shape consumption form, so that the user can easily directly check the state of the second battery 110 .

Thereafter, in step S145, the consumable state or available time determined in step S144 is displayed on the display screen 201 of the wearable device 200 in the second available time display unit 275 according to the present invention.

Therefore, the user can view the consumable state or the talkable time displayed on the display screen 201 of the wearable device 200 and change the BT headset call mode to the device call mode before the second battery 110 of the BT headset 100 is consumed It will be possible to make a transition. As a result, continuous conversation can be continued.
