  The operation detection unit 202 detects an operation on the operation image displayed on the display unit 201. Specifically, the operation detection unit 202 includes a transparent touch panel sensor that covers the display unit 201 and detects a user operation.

The tablet communication unit 204 communicates with the main body communication unit 104 of the main body device 10 by wireless communication or wired communication. In this example, a case where the tablet communication unit 204 and the main body communication unit 104 communicate by wireless communication will be described. The information transmitted and received by the wireless communication includes voice call information and communication information.
Voice call information is information used for voice calls. More specifically, this voice call information is information used for a voice call via a wireless communication line between the wireless communication apparatus 1 and another communication apparatus 2.
Communication information is information used for data communication via a wireless communication line. More specifically, the communication information is information used for data communication via a wireless communication line between the wireless communication device 1 and another communication device 2. That is, the tablet communication unit 204 transmits and receives voice call information used for voice communication via the wireless communication line and communication information used for data communication via the wireless communication line to and from the main body device 10.

  The tablet communication unit 204 may be configured to transmit / receive voice call information to / from the main body communication unit 104 among the voice call information and the communication information. That is, the main body communication unit 104 and the tablet communication unit 204 may be configured to transmit and receive at least one of voice call information and communication information. With this configuration, the wireless communication device 1 can sort the functions so that the main device 10 provides a voice call function and the tablet device 20 provides a data communication function. The wireless communication device 1 can also distribute functions so that the main body device 10 provides a voice call function and the tablet device 20 provides a voice call function and a data communication function. That is, the wireless communication device 1 can provide mutually different functions in the main body device 10 and the tablet device 20. Thereby, according to the wireless communication device 1, the function is provided by the tablet device 20 for the user who is used to the touch panel operation, and the function is provided by the main body device 10 for the user who is not used to the touch panel operation. be able to. That is, according to the wireless communication device 1, it is possible to provide a function that matches the user's characteristics.

  When the tablet communication unit 204 and the main body communication unit 104 communicate by wireless communication, the communication quality determination unit 209 determines the communication quality of the wireless communication. For example, the communication quality determination unit 209 determines the communication quality based on the result of measuring the received signal strength of the radio wave transmitted from the main body communication unit 104 of the main body device 10. In this case, the communication quality determination unit 209 determines that the communication quality is good when the received signal strength is strong, and determines that the communication quality is poor when the received signal strength is weak. Note that instead of the received signal strength, for example, the communication quality determination unit 209 measures an SN ratio (Signal-Noise ratio; signal-to-noise ratio) in reception of a radio wave transmitted from the main body communication unit 104 of the main body device 10. The communication quality may be determined based on the above. In that case, the communication quality determination unit 209 determines that the communication quality is good when the SN ratio is large, and determines that the communication quality is bad when the SN ratio is small.

The communication quality determination unit 209 determines the communication quality of wireless communication between the tablet communication unit 204 and the main body communication unit 104 at a predetermined timing and based on a predetermined determination rule.
As the predetermined timing, for example, the communication quality determination unit 209 measures the communication quality periodically (for example, every second). In addition, as another predetermined timing, for example, the communication quality determination unit 209 may measure the communication quality at a timing at which it is detected that the tablet device 20 has moved. In that case, the tablet device 20 is a sensor (for example, an acceleration sensor) for detecting that its own tablet device 20 has moved, a positioning system (for example, a GPS (Global Positioning System)), or the like. It is desirable to have.

As a predetermined determination rule, for example, the communication quality determination unit 209 determines the communication quality by comparing the communication quality that is the measurement result with the communication quality that is set in advance as a threshold value.
Note that the determination of the communication quality performed by the communication quality determination unit 209 is not limited to the determination based on the simple comparison between the measurement result of the communication quality and the threshold value as described above.
For example, the communication quality determination performed by the communication quality determination unit 209 may be determined according to a temporal change in communication quality. For example, when the measurement result that the communication quality is gradually deteriorated is obtained such as when the tablet device 20 is gradually moving away from the main body device 10, the communication quality determination unit 209 determines that the communication quality is a threshold value. It may be determined that the communication quality has deteriorated even if it is not lower than.
Conversely, when the tablet device 20 is gradually approaching from the main body device 10 and obtains a measurement result that the communication quality is gradually improved, the communication quality determination unit 209 determines that the communication quality is It may be determined that the communication quality has not deteriorated even if it is below the threshold value.

Specifically, for example, wireless communication between the tablet communication unit 204 and the main body communication unit 104 is connected by communication using Bluetooth (Bluetooth (registered trademark)), which is one of the short-range wireless communication standards. In this case, for example, the communication quality determination unit 209 compares the measurement result of the received signal strength (RSSI) of Bluetooth with the received signal strength predetermined as a threshold value, thereby comparing the tablet with the tablet. Communication quality between the communication unit 204 and the main body communication unit 104 is determined.
Note that wireless communication between the tablet communication unit 204 and the main body communication unit 104 is established through communication connection by other communication standards, for example, Wi-Fi (registered trademark), which is a wireless LAN standard compliant with the IEEE 802.11 series standard. May be. In the case of communication connection by Wi-Fi, the communication quality determination unit 209 determines the measurement result of the received signal strength (RSSI) of Wi-Fi and the received signal strength that is predetermined as a threshold value. Is compared to determine the communication quality between the tablet communication unit 204 and the main body communication unit 104.
For example, the received signal strength predetermined as the threshold is “−60 dBm (Decibel-milliwatts)” or the like. For example, the communication quality determination unit 209 determines that the communication quality is degraded when the measurement result of the received signal strength falls below −60 dBm.
And the communication quality determination part 209 outputs the determination result of communication quality as needed.

  The communication quality information output unit 210 acquires a communication quality determination result from the communication quality determination unit 209. In this example, when the communication quality determination unit 209 determines that the communication quality has decreased, the communication quality information output unit 210 acquires a determination result indicating that the communication quality has decreased from the communication quality determination unit 209. When the communication quality determination unit 209 determines that the communication quality has not deteriorated, the communication quality information output unit 210 obtains a determination result indicating that the communication quality has not deteriorated from the communication quality determination unit 209. You may make it do.

  Hereinafter, a case where the tablet device 20 includes a communication module and the main body device 10 establishes communication connection with a communication base station via the tablet device 20 will be described as an example.

  When the main device 10 is in a voice call, that is, when the tablet device 20 and the main device 10 are communicating, the communication quality information output unit 210 obtains a communication quality determination result from the communication quality determination unit 209. The communication quality information output unit 210 executes, for example, the following processing.

  The communication quality information output unit 210 causes the display unit 201 to display an image PCl based on image data indicating a decrease in received signal strength via the tablet control unit 203. Image data indicating a decrease in received signal strength is stored in advance in the tablet storage unit 206. The display unit 201 displays an image PCl based on the acquired image data. This image PCl is an image that notifies the user who is using the tablet device 20 that the received signal strength has decreased. For example, this image contains words such as “Please bring this tablet close to the phone itself. The radio wave is weak.”

  In this example, the communication quality information output unit 210 notifies the user using the tablet device 20 by the image PCl, but may notify the user using a notification means other than the image. For example, if the tablet device 20 has a voice output function, the communication quality information output unit 210 may notify by voice. Further, for example, if the tablet device 20 has a function of generating a stimulus that generates a somatic sensation such as a vibration stimulus by a vibration motor, the communication quality information output unit 210 generates a somatic sensation for the user. You may notify by the stimulus to make.

Further, the communication quality information output unit 210 outputs communication quality deterioration information indicating a decrease in received signal strength to the tablet communication unit 204 via the tablet control unit 203. The tablet communication unit 204 outputs communication quality degradation information to the main body communication unit 104 of the main body device 10.
The main body communication unit 104 acquires communication quality degradation information from the tablet communication unit 204. When the main body communication unit 104 acquires the communication quality degradation information, the main body control unit 103 acquires audio data from the main body storage unit 106, for example. The acquired voice data is superimposed on voice data indicating voice during a voice call via the main body control unit 103 and reproduced by the receiver 110. Alternatively, sound based on the acquired sound data may be reproduced by a speaker other than the handset 110. In this case, the sound based on the acquired sound data is reproduced by the main body sound output unit 108, for example. This voice is reproduced in order to notify the user who is using the main device 10, that is, the user who is engaged in a voice call, that the received signal strength has decreased. For example, the sound to be played back is a message sound such as “Please bring your tablet close to the phone body. The radio wave is weak.” Or a warning sound such as “Put, Pup, Pup”.

  In this example, the main device 10 notifies the user who uses the main device 10, that is, the user who is in a voice call, by voice, but may be a notification means other than voice. For example, the main device 10 may notify the user by blinking a warning light provided in the main device 10. For example, the warning light is an LED lamp (Light Emitting Diode lamp) or the like. In that case, the communication quality information output unit 210 transmits a signal indicating a decrease in received signal strength to the main body control unit 103 of the main body device 10 via the tablet communication unit or the like. When the main body control unit 103 acquires a signal indicating a decrease in received signal strength, the main body control unit 103 blinks a warning light provided in the main body device 10.

Furthermore, the communication quality information output unit 210 notifies the other party's user who is in a voice call (a user who is making a voice call by another communication device 2) that the received signal strength has decreased.
The communication quality information output unit 210 acquires audio data indicating a decrease in received signal strength from the tablet storage unit 206. The acquired voice data is superimposed on voice data indicating voice during a voice call via the tablet control unit 203 and output to the wireless communication module 205. That is, the voice notifying the decrease in the received signal strength is superimposed on the voice during the voice call and reproduced by a voice reproduction unit (for example, a receiver) of the communication device (another communication device 2) of the other user. The For example, the reproduced sound is a message sound such as “the radio wave state of the telephone of the other party is unstable”, or a warning sound such as “Put, Pup, Pup”.

  In this example, the communication quality information output unit 210 notifies the user of the other party of the voice call by voice, but may notify by a notification method other than voice. For example, the communication quality information output unit 210 may perform notification using a message or an image. In this case, the communication quality information output unit 210 transmits text data, image data, or the like indicating a decrease in received signal strength to the other user's call device via the wireless communication module 205. The other user's communication device (another communication device 2) includes a message based on the acquired text data or an image based on the acquired image data, etc. Display a message or image on

  Further, in the above example, the communication quality information output unit 210 is configured to output the information itself indicating the determination result of the communication quality, but is not limited thereto.

For example, the communication quality information output unit 210 changes the signal transmission output in the communication connection between the tablet communication unit 204 and the main body communication unit 104 according to the determination result of the communication quality by the communication quality determination unit 209, etc. Output control may be performed. When performing output control, when the communication quality between the tablet communication unit 204 and the main body communication unit 104 decreases, the wireless communication device 1 increases the signal transmission output to increase the tablet communication unit 204 and the main body communication unit 104. The frequency with which the communication connection between the two is disconnected can be reduced.

  In addition to outputting the communication quality information only when the communication quality is deteriorated, for example, when the communication connection between the tablet communication unit 204 and the main body communication unit 104 is disconnected, the communication quality information output unit 210 may output the communication quality information. In that case, when the communication connection between the tablet communication unit 204 and the main body communication unit 104 is disconnected, the main body control unit 103 displays a warning light (not shown) provided on the front surface of the main body device 10 of itself. ) May be blinked, or a voice message may be reproduced by the main body sound output unit 108 to notify the user that the communication connection has been disconnected.

[Example of operation of wireless communication device]
Next, an example of the operation of the wireless communication device 1 will be described with reference to FIGS. 3 to 6.
FIG. 3 is a flowchart illustrating an example of a flow of processing performed by the wireless communication device 1 according to the present embodiment. The wireless communication device 1 repeatedly executes a mode determination process, a voice call process, and a communication quality information output process. The wireless communication device 1 may execute other processes than the mode determination process, the voice call process, and the communication quality information output process described here. For example, other processing includes data communication processing. Description of the other processing is omitted. Hereinafter, specific examples of the mode determination process, the voice call process, and the communication quality information output process executed by the wireless communication device 1 will be described.

[Mode judgment (installation mode / non-installation mode)]
The mode determination process is a process for determining whether or not the tablet device 20 is attached to the main body device 10. In the following description, the state where the tablet device 20 is mounted on the main body device 10 is also referred to as a mounting mode. In addition, a state in which the tablet device 20 is not attached to the main body device 10 is also referred to as a non-attachment mode. That is, the mode determination process is a process for determining whether the mode is the wearing mode or the non-wearing mode. Either the main body device 10 or the tablet device 20 may execute the mode determination process. In this example, a case where the tablet device 20 executes a mode determination process will be described. In this case, the main body device 10 transmits the holding state information to the tablet device 20 (step S11). Further, the tablet device 20 executes a mode determination process based on the holding state information transmitted from the main body device 10 (step S21).

[Voice call processing]
Next, voice call processing will be described. The voice call process is a process for making a voice call with another communication device 2 via the radio base station 3. In this example, a case where the wireless communication device 1 provides a voice call function by the handset 110 of the main device 10 will be described. In addition, when the tablet device 20 includes the sound detection unit 207 and the sound output unit 208, the tablet device 20 can provide a voice call function, but the description thereof is omitted in this example.

  The tablet device 20 transfers the audio information received from the wireless base station 3 via the wireless communication module 205 to the main device 10. In addition, the tablet device 20 transfers the audio information received from the main body device 10 to the wireless base station 3 via the wireless communication module 205. That is, the tablet device 20 transfers audio information between the wireless base station 3 and the main device 10 (step S22). In addition, the main body device 10 outputs the audio information transferred from the tablet device 20 to the speaker of the receiver 110. The main device 10 transmits the audio information acquired by the microphone of the receiver 110 to the tablet device 20 (step S12). Details of the voice call processing will be described with reference to FIG.

FIG. 4 is a flowchart showing an example of a voice call processing flow by the wireless communication apparatus 1 of the present embodiment. Here, a case where the other communication device 2 is a telephone and the wireless communication device 1 receives a voice call transmitted by the telephone will be described as an example.
The other communication device 2 transmits a voice call to the wireless communication device 1 (step S021). Specifically, the other communication device 2 transmits voice communication to the telephone number of the wireless communication device 1. Next, the wireless base station 3 communicates with the wireless communication module 205 of the wireless communication device 1 to notify that another communication device 2 has made a voice call. Note that the operation of the radio base station 3 is the same as the operation for a known high-speed data communication line, and thus the description thereof is omitted.

  The tablet control unit 203 of the tablet device 20 detects an incoming voice call via the wireless communication module 205 (step S2210). Next, the tablet control unit 203 transmits information indicating an incoming voice call to the main body control unit 103 of the main body device 10 (step S2220). In addition, although the tablet communication part 204 and the main body communication part 104 intervene in transmission / reception between the tablet control part 203 and the main body control part 103, the description is abbreviate | omitted below.

  When the main body control unit 103 receives information indicating an incoming voice call from the tablet control unit 203 (step S1210), the main body control unit 103 outputs a telephone ringtone (step S1220). The telephone ring tone has its sound source data stored in advance in the main body storage unit 106 and is output from the speaker of the main body sound output unit 108.

In step S2210, the tablet control unit 203 may transmit (A) a predetermined number of times (for example, one time) of information indicating an incoming voice call, and (B) the main body device 10 detects off-hook. You may continue to send until
In the case of (A) described above, the main body control unit 103 continues to output a ringtone until receiving information indicating an incoming call response. When the main body device 10 or the tablet device 20 makes an incoming call response, the tablet control unit 203 transmits information indicating the incoming call response to the main body control unit 103. When receiving information indicating an incoming call response, the main body control unit 103 stops outputting the ringtone.
In the case of (B) described above, the main body control unit 103 continues to output a ringtone while receiving information indicating an incoming voice call. When the main device 10 or the tablet device 20 makes an incoming call response, the tablet control unit 203 stops transmitting information indicating an incoming voice call. When the main body control unit 103 stops receiving information indicating an incoming voice call, it stops outputting the ringtone.

  The main body control unit 103 acquires the detection result of the handset holding detection unit 111, that is, information indicating the hook state of the handset 110 from the handset holding detection unit 111 (step S1230). The information indicating the hook state of the handset 110 indicates either on-hook or off-hook. When the information indicating the hook state indicates off-hook, the information indicating the hook state indicates that the handset 110 has been removed from the main body device 10 in order to make a call. That is, when the information indicating the hook state indicates off-hook, it indicates that the handset 110 has been lifted.

  Next, the main body control unit 103 determines whether or not the user has lifted the handset 110. That is, the main body control unit 103 determines whether or not the information indicating the hook state acquired in step S1230 indicates off-hook (step S1240). If the information indicating the hook state indicates off-hook (step S1240; YES), the main body control unit 103 advances the process to step S1250. On the other hand, if the information indicating the hook state does not indicate off-hook, that is, if it indicates on-hook (step S1240; NO), the main body control unit 103 returns the process to step S1240.

Next, the main body control unit 103 stops the ring tone that has been output in step S1220 (step S1250).
In addition, although the case where the incoming call response by the user is performed in the main body device 10 from step S1230 to step S1250 has been described, the incoming call response may be performed in the tablet device 20. In this case, the tablet control unit 203 determines whether or not the user has made an incoming call response. When it is determined that the user has made an incoming call response, the tablet control unit 203 transmits information indicating that the incoming call response has been made to the main body control unit 103. When receiving information indicating that the incoming call response has been made, the main body control unit 103 stops the ring tone.

  Next, the main body control unit 103 transmits information indicating the hook state acquired in step S1230 to the tablet control unit 203 (step S1260).

  The tablet control unit 203 receives the information indicating the hook state transmitted in step S1260 (step S2230). The tablet control unit 203 can determine whether or not the handset 110 has been lifted by receiving information indicating the hook state. Here, the information indicating the hook state transmitted in step S1260 indicates that the handset 110 has been lifted. That is, the tablet control unit 203 determines in step S2230 that the handset 110 has been lifted. The off-hook operation of the handset 110 is a response instruction for a call connection with another communication device 2. When determining that the handset 110 has been lifted, the tablet control unit 203 advances the process to step S2240 and makes a response to the incoming call from the other communication device 2.

  Next, the tablet control unit 203 and the other communication device 2 start transmission / reception of audio information to / from each other (steps S2240 and S022).

Next, voice call processing is performed among the main body control unit 103, the tablet control unit 203, and another communication device 2. An example of this voice call processing is shown by a processing group (step STel) surrounded by a broken line in FIG. This voice call process includes a process when the wireless communication apparatus 1 is the receiving side and a process when the wireless communication apparatus 1 is the transmitting side.
First, processing when the wireless communication apparatus 1 is the receiving side will be described. The other communication device 2 transmits voice information (step S023). When the tablet control unit 203 receives the voice information transmitted in step S023 (step S201), the tablet control unit 203 transfers the received voice information to the main body control unit 103 (step S202). The main body control unit 103 receives the audio information transmitted in step S202 (step S101).
Next, processing when the wireless communication apparatus 1 is the transmission side will be described. The main body control unit 103 transmits audio information (step S102). When the tablet control unit 203 receives the audio information transmitted in step S102 (step S203), the tablet control unit 203 transfers the received audio information to another communication device 2 (step S204). The other communication device 2 receives the audio information transmitted in step S204 (step S024).

  This voice call processing is continued until the user places the handset 110 in the handset holding unit 112 of the main body device 10. The main body control unit 103 acquires the detection result of the handset holding detection unit 111, that is, information indicating the hook state of the handset 110, and determines whether or not it is on-hook (step S1270). If it is determined that the main body control unit 103 is on-hook (step S1270; YES), the process proceeds to step S1280. If the main body control unit 103 determines that it is not on-hook (step S1270; NO), it continues the voice call process.

  In step S1280, the main body control unit 103 transmits information indicating the hook state of the handset 110 to the tablet control unit 203. The tablet control unit 203 receives the information indicating the hook state transmitted in step S1280 (step S2250). Here, the information indicating the hook state transmitted in step S1280 indicates that the handset 110 is placed in the handset holding unit 112. That is, the tablet control unit 203 determines in step S2250 that the handset 110 has been placed. The on-hook operation of the handset 110 is an instruction to end a call connection with another communication device 2. If the tablet control unit 203 determines that the handset 110 has been placed, the process proceeds to step S <b> 2260, and the call connection with the other communication device 2 is terminated.

  The tablet control unit 203 and the other communication device 2 end the transmission / reception of audio information (steps S2260 and S025).

[Communication quality information output]
Returning to FIG. 3, the communication quality information output process will be described.
In the communication quality information output process, the communication quality information output unit 210 of the tablet device 20 performs the display unit 201 of the tablet device 20, the main body device 10, and another communication device 2 (voice communication via a wireless communication line). This is a process for outputting the communication quality information to the partner device).
With the communication quality information, the communication quality determination unit 209 of the main device 10 determines the state of communication quality between the main device 10 and the tablet device 20, and the communication quality information output unit 210 outputs based on the determination result. Information. For example, the communication quality information is based on a determination result that the communication quality between the main body device 10 and the tablet device 20 has deteriorated, and at least one of the tablet device 20, the main body device 10, and the other communication device 2 This is information for outputting a warning to each user.

  In this example, a case where the wireless communication device 1 provides a communication quality information output function by the communication quality determination unit 209 and the communication quality information output unit 210 of the tablet device 20 will be described. In addition, when the main body device 10 includes the communication quality determination unit 209 and the communication quality information output unit 210, the main body device 10 can provide a communication quality information output function. Is omitted.

Further, in this example, a case where a voice call is performed by the handset 110 of the main body device 10 on the wireless communication device 1 side will be described.
FIG. 5 is a flowchart showing an example of a flow of communication quality information output processing by the wireless communication apparatus 1 of the present embodiment.
The process illustrated in FIG. 5 is started when a voice call process is performed between the wireless communication device 1 (the main device 10 and the tablet device 20) and the other communication device 2 (step STel).

  First, the communication quality determination unit 209 of the tablet device 20 measures the received signal strength (RSSI) of the communication connection with the main device 10 periodically (for example, every second). The communication quality determination unit 209 determines the communication quality by comparing the received signal strength as a measurement result with the received signal strength determined in advance as a predetermined threshold value. When the measurement result of the received signal strength is below the threshold, the communication quality determination unit 209 determines that the communication quality is in a degraded state (step S2310; YES).

When the communication quality determination unit 209 determines that the communication quality is degraded, the communication quality information output unit 210 outputs image data indicating a decrease in received signal strength to the display unit 201 via the tablet control unit 203. .
The display unit 201 displays an image based on the acquired image data (step S2320). Note that an image based on image data indicating a decrease in received signal strength is hereinafter also referred to as a notification image. An example of the notification image displayed on the display unit 201 will be described later.

When the communication quality determination unit 209 determines that the communication quality is degraded, the communication quality information output unit 210 outputs audio data indicating a decrease in received signal strength to the tablet communication unit 204 via the tablet control unit 203. To do. The tablet communication unit 204 outputs the acquired audio data to the main body communication unit 104. (Step S2330).
The main body communication unit 104 outputs the acquired audio data to the main body control unit 103. The main body control unit 103 reproduces sound based on the acquired sound data by the receiver 110. Alternatively, the main body control unit 103 causes the main body sound output unit 108 to reproduce sound based on the acquired sound data (step S1310).

In addition, when the communication quality determination unit 209 determines that the communication quality has deteriorated, the communication quality information output unit 210 outputs audio data indicating a decrease in received signal strength to the other communication device 2. (Step S2340).
The other communication device 2 reproduces the voice based on the acquired voice data by a voice reproduction unit (for example, a receiver, a speaker, etc.) provided in the other communication device 2 of itself. (Step S031).

When the communication connection between the tablet communication unit 204 and the main body communication unit 104 is disconnected (step S2350; YES), the tablet control unit 203 determines that the tablet control unit 203 and the other communication device 2 have audio information. Is terminated (steps S2380 and S032).
In this example, when the communication connection between the tablet communication unit 204 and the main body communication unit 104 is disconnected, the transmission / reception of audio information is terminated, but the present invention is not limited to this. For example, the tablet control unit 203 and the other communication device 2 communicate with each other until the communication connection between the tablet communication unit 204 and the main body communication unit 104 is reconnected. May be put on hold.

When the communication connection between the tablet communication unit 204 and the main body communication unit 104 is not disconnected (step S2350; NO), the main body control unit 103 determines that the communication quality determination unit 209 of the tablet device 20 again The received signal strength (RSSI) of the communication connection between the communication unit 204 and the main body communication unit 104 is measured. The communication quality determination unit 209 determines the communication quality by comparing the received signal strength as a measurement result with the received signal strength determined in advance as a predetermined threshold value.
When the measurement result of the received signal strength is below the threshold value (step S2360; YES), the communication quality determination unit 209 determines that the communication quality is in a degraded state. When the reception signal strength measurement result is equal to or greater than the threshold (step S2360; NO), the communication quality determination unit 209 determines that the communication quality has recovered again.
