With the above processing, the CDL master device 100 is in a state of waiting for a reproduction operation, and guidance for a reproduction operation, a music menu, and the like are displayed on the display unit 106.

  Even when a music link operation is performed in one CDL slave device (for example, CDL slave device 200A) that can be connected to the CDL master device 100, music is sent from the CDL slave device 200A to the CDL master device 100 by a DECT signal. A cooperation start request is sent, and the cooperation start request is transferred to the Bluetooth (registered trademark) control unit 123 in the CDL master device 100, and the CDL master device 100 and the CDL slave device 200 are in a state waiting for a reproduction operation by the same processing as described above. Thus, guidance such as a reproduction operation and a music menu are displayed on the display unit.

<Cooperation control example 2>
Next, the flow of processing when the user performs a music playback start operation will be described with reference to FIG.

  After the process shown in FIG. 7, the user performs an operation to start reproduction. In FIG. 8, when a playback start operation (PLAY_KEY is pressed) is performed on the operation unit 105 of the CDL base unit 100 (S321), the base unit control unit 109 in the CDL base unit 100 causes the Bluetooth (registered trademark) of the CDL base unit 100 to be registered. ) The operation information (PLAY_KEY notification) of the reproduction start operation is sent to the base unit communication unit of the APP layer of the control unit 123 (S322).

  Next, the base unit communication unit sends operation information of the reproduction start operation to the AVRCP control unit (S323). Next, the AVRCP control unit sends operation information of the reproduction start operation to the Bluetooth (registered trademark) communication I / F unit 124 (S324). Then, the operation information of the playback start operation is transmitted from the Bluetooth (registered trademark) communication I / F unit 124 to the mobile phone 30a, and the mobile phone 30a starts the playback operation.

  The mobile phone 30a sends a signal (Stream start request) requesting the start of audio streaming to the CDL master device 100. Then, the Bluetooth (registered trademark) communication I / F unit 124 sends a Stream start request to the A2DP control unit (S325). The A2DP control unit sends a sound path control signal instructing formation of a sound path used for music cooperation to the BT sound control unit of the Middle layer (S326).

  In accordance with the sound path control signal, the BT sound control unit forms a sound path for music cooperation. After the voice path is formed, the BT voice control unit sends a sound path control response indicating that to the A2DP control unit (S327).

  Then, the A2DP control unit sends a signal (Stream start response) indicating that the Stream start request has been received to the Bluetooth (registered trademark) communication I / F unit 124 (S328). This Stream Suspend response is transmitted from the Bluetooth (registered trademark) communication I / F unit 124 to the mobile phone 30a.

  When these exchanges are completed, the A2DP control unit sends a reproduction start notification to the base unit communication unit (S329). Then, the base unit communication unit sends an AV playback start notification to base unit control unit 109 (S330).

  In this way, the audio signal to be played, which is sent from the mobile phone 30a to the CDL master device 100, is transmitted to the CDL master device 100 via the broadband wireless resource already reserved by the Bluetooth (registered trademark) control unit 123. Is done. The audio signal is output from the speakers 129 and 130 of the CDL master device 100. As a result, a playback sound is heard and music playback is started (S331).

  Therefore, it is possible to output the audio reproduced by the mobile phone using the speaker of the cordless telephone master unit. In addition, it is possible to remotely control music playback on a mobile phone using a cordless telephone cordless handset. Further, since wireless communication is performed between the mobile phone having the music playback function and the cordless telephone device, it is not necessary for the user to move each time the music playback operation is performed.

  As described above, when a music cooperation operation is performed on the cordless telephone device, first, it is confirmed that the mobile phone is within the communicable range of the parent device, and then the Bluetooth (registered trademark) control unit 123 performs the music cooperation. By starting the control to acquire the necessary radio resources, radio resources are secured when the user performs a playback start operation, and a high-quality playback sound can be played immediately according to the playback start operation. If it is not possible to confirm that the mobile phone is within the communicable range of the master unit, an error message “cooperation impossible” is displayed.

<Coordination control example 3>
Next, a flow of processing when an incoming call occurs in the mobile phone 30a during music reproduction by music cooperation will be described with reference to FIG.

  After the processing shown in FIG. 8, when an incoming call occurs in the mobile phone 30a during music reproduction (S401), the incoming call information is transmitted from the mobile phone 30a to the CDL master device 100 via Bluetooth (registered trademark) communication. Next, the Bluetooth (registered trademark) communication I / F unit 124 of the CDL master device 100 notifies the HFP control unit of the Bluetooth (registered trademark) control unit 123 of the incoming bell (S402). For example, when an incoming call occurs in the mobile phone 30a used for music linkage, the Bluetooth (registered trademark) control unit 123 starts a process of surrendering radio resources for a call (high priority) according to the incoming call information.

  In FIG. 9, process A shows a process of surrendering radio resources for a call. In process A, first, the HFP control unit immediately sends a resource request for a voice call to the BT radio control unit of the Middle layer in accordance with the bell incoming notification sent from the Bluetooth (registered trademark) communication I / F unit 124. Perform (S403). The resource request in this case is a request for communication resources in the Talk mode between the CDL master device 100 and the mobile phone 30a (type = mobile phone 30a, mode = Talk). Upon receiving this resource request, the BT radio control unit starts processing for switching the Bluetooth (registered trademark) radio communication mode from the AV mode to the Talk mode, and notifies the HFP control unit of a resource response (S404).

  The HFP control unit that has received the resource response notification starts the mobile incoming call sequence with the base unit control unit 109 in the CDL base unit 100, thereby notifying the base unit control unit 109 of the incoming call of the mobile phone 30a ( S405). In response to this notification, base unit control section 109 performs control for ringing the incoming call ring tone. By this control, ringing of the incoming call bell sound is started from the speakers 129 and 130 of the CDL master device 100 (S406).

  In FIG. 9, process B is a process for switching from the AV mode to the Talk mode to stop music playback. The BT radio control unit that has received the above resource request activates a process for switching the radio communication mode from the AV mode to the Talk mode to stop music reproduction.

  That is, the BT radio control unit notifies the AVRCP control unit of resource release meaning that the resource for the AV mode has been released (S407). Receiving this notification, the AVRCP control unit sends a Stream stop notification indicating stop of streaming to the A2DP control unit (S408).

  Next, according to the stream stop notification, the A2DP control unit notifies the master unit communication unit of the end of music playback (S409). Next, in accordance with the notification, the base unit communication unit notifies the master unit control unit 109 of the CDL base unit 100 of the end of AV playback, which means the end of music playback (S410).

  Further, the AVRCP control unit receives a resource release described above, and sends a control signal (PAUSE / STOP_KEY notification) for stopping the reproduction operation of the mobile phone 30a (S411). This control signal is transmitted to the mobile phone 30a via the Bluetooth (registered trademark) communication I / F unit 124, and the playback operation of the mobile phone 30a is stopped (S412).

  Then, the cellular phone 30a sends a signal (Stream Suspend request) to stop the audio streaming to the CDL master device 100. This Stream Suspend request is sent from the Bluetooth (registered trademark) communication I / F unit 124 to the A2DP control unit (S413). Thereafter, a signal (Stream Suspend response) indicating that a Stream Suspend request has been received is sent from the A2DP control unit to the Bluetooth (registered trademark) communication I / F unit 124 (S414). Then, the Stream Suspend response is transmitted from the Bluetooth (registered trademark) communication I / F unit 124 to the mobile phone 30a.

  When these exchanges are completed, the A2DP control unit sends a sound path control signal instructing stop (music communication stop) of formation of a voice path for music cooperation to the BT wireless control unit of the Middle layer (S415). In accordance with the sound path control signal, the BT radio control unit stops the formation of the voice path for music cooperation that has been formed so far, and sends a sound path control response to the A2DP control unit (S416). Thereby, the transition from the AV mode to the Talk mode is completed. Further, the music playback sound stops at the speakers 129 and 130 of the CDL master device 100 (S417).

  Through the above processing, wideband voice (music) playback is stopped, and the CDL master device 100 and the mobile phone 30a transition to the mobile incoming call mode.

  Note that, when the incoming call information sent from the mobile phone 30a includes information related to the caller, the base unit control unit 109 of the CDL base unit 100 displays the information related to the caller on the display unit 106. Alternatively, base unit control unit 109 retrieves related information from the telephone directory database stored in storage unit 103 according to the information and displays it on display unit 106.

  Further, when the mobile phone control unit 109 is notified of the mobile incoming call by the mobile incoming call sequence, it also notifies the mobile phone incoming call to the CDL slave device 200 (for example, the CDL slave device 200A) that can be connected to the master phone. . In other words, a signal indicating that a mobile incoming call has occurred is transmitted by the DECT signal via the CDL wireless I / F unit 107. In accordance with the signal, in the CDL slave unit 200, the slave unit control unit 147 controls ringing of the incoming call bell. By this control, ringing of the ringing bell sound is started at the speaker 152.

  As described above, when the mobile incoming call sequence (S405) is started with the base unit control unit 109 in the CDL base unit 100, the ringing of the incoming ring tone is started by the speakers 129 and 130 of the CDL base unit 100. (S406). The user can know the occurrence of an incoming call at the mobile phone 30a by ringing the incoming call bell.

  As described above, since the wireless communication mode switching process is automatically performed before the user performs an incoming call response operation in parallel with the ringing of the ringing bell, the user performs an operation for switching the wireless communication mode. There is no need.

<Cooperation control example 4>
Next, referring to FIG. 10, an operation in which an incoming call occurs in the mobile phone 30 a during music reproduction by music cooperation and a user who notices the incoming call by ringing of the incoming call bell sound in the CDL device 1 responds to the incoming call. The flow of processing when it is performed will be described.

In accordance with the sound path control signal, the BT sound control unit stops the sound path for the previous music linkage and sends a sound path control response to the A2DP control unit (S612). As a result, the playback sound of music stops at the speakers 129 and 130 of the CDL master device 100.

  In FIG. 12, the process D shows the process when a transmission number is input. In process D, when the user inputs a calling number (for example, 123-456-7890) for calling the mobile phone network 50 in the CDL master device 100 or the CDL slave device 200 (S613), the master device control of the CDL master device 100 is performed. The unit 109 transfers the transmission number to the Bluetooth (registered trademark) control unit 123 (S614 to S615). Here, although it is assumed that the transmission number is input by the user in S613, the transmission number may be input in S601 in the operation of transmission. In this case, base unit control unit 109 automatically transfers the calling number to the Bluetooth (registered trademark) control unit 123 (without user operation).

  Next, the HFP control unit of the Bluetooth (registered trademark) control unit 123 immediately makes a resource request for a voice call to the BT radio control unit of the Middle layer (S616). The resource request in this case is a request for communication resources in the Talk mode between the CDL master device 100 and the mobile phone 30a (type = mobile phone 30a, mode = Talk). Upon receiving this resource request, the BT radio control unit starts processing for switching the Bluetooth (registered trademark) radio communication mode from the AV mode to the Talk mode, and notifies the HFP control unit of a resource response (ok) (S617).

  Upon receiving the resource response notification, the HFP control unit starts a call activation sequence between the mobile phone 30a and the CDL master device 100. That is, the HFP control unit transmits the input transmission number (for example, 123-456-7890) to the mobile phone 30a via the Bluetooth (registered trademark) communication I / F unit 124 (S618). In accordance with the transmission of the calling number, the cellular phone 30a starts a process of calling the cellular phone network 50 and transmits the calling number to the cellular phone network 50. Then, the mobile phone 30a sends a status notification indicating that the calling is in progress to the CDL master device 100 (S619).

  Then, when the mobile phone 30a enters a call state to the other party after transmitting the transmission number to the mobile phone network 50, the mobile phone 30a sends a signal (voice link request) for requesting voice link establishment to the CDL master device 100 ( S620).

  Next, in accordance with the voice link request, the HFP control unit of the CDL base unit 100 starts control related to the connection activation between the CDL base unit 100 and the mobile phone 30a, and the Bluetooth (registered trademark) communication I / F unit 124. A voice link response is sent to the mobile phone 30a via (step S621).

  Then, the HFP control unit controls the BT voice control unit to form a voice path for a call (S622). Thereby, a two-way voice communication path is formed between the CDL master device 100 and the mobile phone 30a. However, at this stage, the mobile phone 30a transmits a call number to the mobile phone network 50 and makes a call to the other party (that is, the other party is not responding).

  Thereafter, in FIG. 13, when the calling party responds and the connection of the communication path between the mobile phone 30a and the call partner is completed, the mobile phone 30a sends the call to the HFP control unit via the Bluetooth (registered trademark) communication I / F unit 124. A status notification (partner response) indicating a response is sent (S623). As a result, a voice call is started (S624), and a transition is made to a mobile call mode between the call partner and the CDL master device 100 (during a call).

  As described in connection control example 4 above, also in this connection control example, when a user makes a call using the CDL slave device 200, the user's voice is sent to the CDL master device 100, and the CDL master device 100 Is sent to the mobile phone 30a via the Bluetooth (registered trademark) communication I / F unit 124 by a voice path for a call. In addition, the voice of the other party of the call received by the mobile phone 30a is received by the Bluetooth (registered trademark) communication I / F unit 124 of the master unit, passes through the voice path for the call, and is sent from the CDL master unit 100 to the CDL. It is sent to handset 200 and can be heard as sound from speaker 152.

  With the above processing, even when the CDL master device 100 or the CDL slave device 200 is operated to make a call to the mobile phone network 50 during the music playback operation, the CDL master device 100 or the CDL slave device 200 is also operated. In conjunction with the outgoing operation, the Bluetooth (registered trademark) control unit 123 of the CDL master device 100 immediately releases high-quality radio resources and stops the audio stream, so that the music playback operation is forcibly terminated. Then, since the radio resources for the call are re-acquired, the Bluetooth (registered trademark) control unit 123 can start calling the mobile phone 30 via the Bluetooth (registered trademark) communication I / F unit 124. .

  Note that in FIG. 13, the process flow when the user performs an operation to end the call after shifting to the mobile call mode (during a call) is the same as the process flow (S <b> 512 to S <b> 523) shown in FIG. 11 described above. It is.

<Cooperation control example 7>
Next, with reference to FIG. 14, a description will be given of a processing flow when the user performs an operation of pausing music playback during music playback.

  When a pause operation (PAUSE_KEY pressing) for instructing pause of music being played is performed in the operation unit 105 of the CDL master unit 100 (S701), the master unit control unit 109 in the CDL master unit 100 Operation information (PAUSE_KEY notification) of the pause operation is sent to the base unit communication unit of the APP layer of the 100 Bluetooth (registered trademark) control unit 123 (S702). Next, the base unit communication unit sends operation information of the pause operation to the AVRCP control unit (S703).

  In FIG. 14, a process E shows a process of pausing music playback. In the process E, the AVRCP control unit sends a Stream pause notification indicating a pause of streaming to the A2DP control unit (S704). In accordance with the notification, the A2DP control unit notifies the base unit communication unit of a temporary stop (S705). In accordance with the notification, the base unit communication unit notifies the base unit control unit 109 of the CDL base unit 100 of a temporary stop (S706).

  Further, the AVRCP control unit receives the operation information of the pause operation notified from the base unit communication unit, and sends a control signal (PAUSE_KEY notification) for pausing the playback operation of the mobile phone 30a (S707). This control signal is transmitted to the mobile phone 30a via the Bluetooth (registered trademark) communication I / F unit 124, and the playback operation of the mobile phone 30a is temporarily stopped.

  Then, the cellular phone 30a sends a signal (Stream Suspend request) instructing the temporary stop of the audio streaming to the CDL master device 100. This signal is sent to the A2DP control unit via the Bluetooth (registered trademark) communication I / F unit 124 (S708).

  Next, the A2DP control unit transmits a signal (Stream Suspend response) indicating that the Stream Suspend request has been received to the mobile phone 30a via the Bluetooth (registered trademark) communication I / F unit 124 (S709).

  When these exchanges are completed, the A2DP control unit sends a sound path control signal for instructing suspension of music communication to the BT audio control unit of the Middle layer (S710). In accordance with the sound path control signal, the BT radio control unit temporarily stops the sound path for the music cooperation so far and sends a sound path control response to the A2DP control unit (S711). As a result, the music playback sound stops at the speakers 129 and 130 of the CDL master device 100 (S712).

<Cooperation control example 8>
Next, the flow of processing when an incoming call occurs in the mobile phone 30a while music playback is paused will be described with reference to FIG.

  After the processing shown in FIG. 14, when an incoming call occurs in the mobile phone 30a that has paused music playback (S801), the incoming call information is transmitted from the mobile phone 30a via Bluetooth (registered trademark) communication, and the CDL parent The Bluetooth (registered trademark) communication I / F unit 124 of the device 100 notifies the HFP control unit of the Bluetooth (registered trademark) control unit 123 of the incoming ringing (S802). For example, when a mobile phone call is generated in the mobile phone 30a that has paused music playback (S801), the Bluetooth (registered trademark) control unit 123 uses the incoming call information to call a radio resource (high priority). The process of surrendering for the purpose is started.

  In FIG. 15, process A shows a process of surrendering radio resources for a call. In the process A, the HFP control unit first requests a resource request for a voice call to the BT radio control unit of the Middle layer according to the bell incoming notification sent from the Bluetooth (registered trademark) communication I / F unit 124. (S803). The resource request in this case is a request for communication resources in the Talk mode between the CDL master device 100 and the mobile phone 30a (type = mobile phone 30a, mode = Talk). Upon receiving this resource request, the BT radio control unit starts a process of switching the Bluetooth (registered trademark) radio communication mode from the AV mode to the Talk mode, and notifies the HFP control unit of a resource response (S804).

  Receiving the resource response notification, the HFP control unit starts the mobile incoming call sequence with the parent device control unit 109 in the CDL parent device 100, thereby notifying the parent device control unit 109 of the mobile incoming call in the mobile phone 30a. (S805). Receiving this notification, base unit control section 109 controls ringing of the incoming call bell. By this control, ringing of the incoming call bell sound is started at the speaker of the CDL master device 100 (S806).

  In FIG. 15, the process F switches from the AV mode to the Talk mode, and changes from a state in which music playback is paused (hereinafter referred to as a paused state) to a state in which music playback is stopped (hereinafter referred to as a stopped state). It is processing. The BT radio control unit that has received the above resource request switches the radio communication mode from the AV mode to the Talk mode, and starts processing for changing from the pause state to the stop state.

  That is, the BT radio control unit notifies the AVRCP control unit of resource release meaning that the resource for the AV mode has been released (S807). Receiving this notification, the AVRCP control unit sends a Stream stop notification indicating stop of audio streaming to the A2DP control unit (S808). Next, in accordance with the stream stop notification, the A2DP control unit notifies the master unit communication unit of the end of music playback (S809). Next, in accordance with the notification, the base unit communication unit notifies the end of AV playback to the base unit control unit 109 of the CDL base unit 100 (S810).

  Further, the AVRCP control unit receives a resource release described above, and sends a control signal (STOP_KEY notification) for putting the mobile phone 30a into a stop state (S811). The control signal is transmitted to the mobile phone 30a via the Bluetooth (registered trademark) communication I / F unit 124, and the pause state is changed to the stop state in the mobile phone 30a (S812). In this way, the continuation of the pause state is eliminated. Therefore, it is possible to prevent an unexpected operation from being performed in the mobile phone 30a by continuing the pause state.

  Then, the cellular phone 30a sends a signal (Stream Suspend request) to stop the audio streaming to the CDL master device 100. This Stream Suspend request is sent from the Bluetooth (registered trademark) communication I / F unit 124 to the A2DP control unit (S813). Thereafter, the A2DP control unit sends a signal (Stream Suspend response) indicating that the Stream Suspend request has been received to the Bluetooth (registered trademark) communication I / F unit 124 (S814). This Stream Suspend response is transmitted from the Bluetooth (registered trademark) communication I / F unit 124 to the mobile phone 30a.

  When these exchanges are completed, the A2DP control unit sends a sound path control signal for instructing stop of formation of a voice path for music cooperation (stop of music communication) to the BT wireless control unit of the Middle layer (S815). ). In accordance with the sound path control signal, the BT radio control unit stops the formation of the voice path for music cooperation that has been formed so far, and sends a sound path control response to the A2DP control unit (S816). This completes the transition from the AV mode to the Talk mode (portable call mode). Further, the temporary stop state is changed to the stop state in the CDL master device 100 (S817).

  As a result of the above processing, the pause state of wideband voice (music) playback is changed to the stopped state, and the CDL master device 100 and the mobile phone 30a transition to the mobile call mode.

  Note that, when the incoming call information sent from the mobile phone 30a includes information related to the caller, the base unit control unit 109 of the CDL base unit 100 displays the information related to the caller on the display unit 106. Alternatively, base unit control unit 109 retrieves related information from the telephone directory database stored in storage unit 103 according to the information and displays it on display unit 106.

  In addition, when the mobile phone control unit 109 is notified of the mobile incoming call by the mobile incoming call sequence (S805), the mobile phone incoming call is also sent to the CDL slave device 200 (for example, the CDL slave device 200A) connectable to the master device. To be notified. In other words, a signal indicating that a mobile incoming call has occurred is transmitted by the DECT signal via the CDL wireless I / F unit 107. In accordance with the signal, the handset controller 147 of the CDL handset 200 controls ringing of the incoming call bell. By this control, ringing of the ringing bell sound is started at the speaker 152.

  As described above, when the mobile incoming call sequence (S805) is started with the parent device control unit 109 in the CDL parent device 100, ringing of the incoming call bell sound is started by the speakers 129 and 130 of the CDL parent device 100. (S806). The user can know the occurrence of an incoming call at the mobile phone 30a by ringing the incoming call bell.

  As described above, since the wireless communication mode switching process is automatically performed before the user performs an incoming call response operation in parallel with the ringing of the ringing bell, the user performs an operation for switching the wireless communication mode. There is no need.

  In FIG. 15, the process flow when the user performs an incoming call response operation after shifting to the mobile incoming call mode is the same as the process shown in FIG. 10 (S502 to S508). Furthermore, after the transition to the mobile call mode (during a call), the process flow when the user performs an operation to end the call is the same as the process (S512 to S523) shown in FIG.

  As described above, according to the present cooperative control example, when there is an incoming call to the mobile phone 30a during the pause of reproduction of audio data by music cooperation, the mobile phone is changed from the paused state to the stopped state, The continuation of the stopped state is resolved. Therefore, it is possible to prevent an unexpected operation from being performed in the mobile phone by continuing the pause state.

<Cooperation control example 9>
Next, the flow of processing when the user performs a telephone directory transfer start operation will be described with reference to FIGS.

  First, as shown in FIG. 16, in the CDL master device 100, a phone book transfer start operation which is an instruction to transfer the phone book data stored in the storage unit 304 of the mobile phone 30a to the storage unit 103 of the CDL master device 100. Is performed (S901), the base unit control unit 109 in the CDL base unit 100 sends a phone book transfer start request to the APP layer of the Bluetooth (registered trademark) control unit 123 of the CDL base unit 100 (S902).

  In accordance with the phone book transfer start request, the base station communication unit sends a phone book transfer start request to the PBAP control unit (S903). The PBAP control unit controls connection / disconnection (disc) of a route for transferring a telephone directory.

  Next, the PBAP control unit that has received the phone book transfer start request makes a resource request to the BT radio control unit in the Middle layer (S904). The resource request in this case is a request for communication resources in the phone book transfer mode between the CDL master device 100 and the mobile phone 30a (type = phone book transfer a, mode = phone book transfer mode). Upon receiving this resource request, the BT radio control unit performs processing for switching the Bluetooth (registered trademark) radio communication mode to the telephone directory transfer mode (S905), and notifies the PBAP control unit of a resource response (S906).

  Next, the PBAP control unit instructs the Bluetooth (registered trademark) communication I / F unit 124 to start PBAP connection (S907).

  Next, according to the PBAP connection activation instruction, the Bluetooth (registered trademark) communication I / F unit 124 (wireless communication circuit) transmits a wireless signal for wireless connection to the mobile phone 30a. Then, the Bluetooth (registered trademark) communication I / F unit 124 determines whether a wireless connection with the mobile phone 30a is possible depending on whether a normal response is returned from the mobile phone 30a to the wireless signal. The process which confirms is performed.

  As a result of the confirmation, if wireless connection is possible with the mobile phone 30a, the Bluetooth (registered trademark) communication I / F unit 124 secures the minimum necessary channels and slots for wireless communication, and the Bluetooth (registered trademark). ) A PBAP connection response indicating completion of wireless connection is sent to the PBAP control unit of the control unit 123 (S908).

  Next, the PBAP control unit that has received the PBAP connection response sends a telephone book transfer (PULL) start request to the Bluetooth (registered trademark) communication I / F unit 124 (S909). This request includes, for example, the number of phone book data to be transferred (for example, 1 to 6000) specified by the user at the time of starting the phone book transfer, and the contents of the phone book data to be transferred. (For example, name, telephone number).

  Next, in accordance with the phone book transfer (PULL) start request, the Bluetooth (registered trademark) communication I / F unit 124 and the wireless communication channel capable of transferring the specified phone book data to and from the mobile phone 30a Secure the slot.

  When a wireless resource having a wireless band necessary for the phone book transfer with the mobile phone 30a is secured, the Bluetooth (registered trademark) communication I / F unit 124 uses the PBAP of the Bluetooth (registered trademark) control unit 123. A telephone directory transfer (PULL) start response is sent to the control unit (S910).

  Next, the PBAP control unit that has received the phone book transfer (PULL) start response sends a phone book transfer start response to the base unit communication unit (S911). Next, the base unit communication unit sends a telephone directory transfer start response to base unit control unit 109 (S912).

  Next, as shown in FIG. 17, process G is performed. Process G indicates a transfer process for one phone book data. The process G is automatically performed (regardless of a user operation).

  For example, when transfer of the first phonebook data is performed, first, the base unit control unit 109 sends a data acquisition request to the base unit communication unit (S913). Next, the base unit communication unit sends a data acquisition request to the PBAP control unit (S914). Next, the PBAP control unit sends a data acquisition request to the Bluetooth (registered trademark) communication I / F unit 124 (S915). This data acquisition request is sent from the Bluetooth (registered trademark) communication I / F unit 124 to the mobile phone 30a.

  Next, according to the data acquisition request, the mobile phone 30a reads the first phone book data (name, phone number) from the storage unit 304. Then, the mobile phone 30a sends the read phonebook data to the Bluetooth (registered trademark) communication I / F unit 124 as a data acquisition response.

  Next, the Bluetooth (registered trademark) communication I / F unit 124 sends a data acquisition response to the PBAP control unit (S916). Next, the PBAP control unit sends a data acquisition response to the base unit communication unit (S917). Next, the base unit communication unit sends a data acquisition response to base unit control unit 109 (S918).

  Then, base unit control unit 109 stores the first phone book data received as the data acquisition response in storage unit 103 of CDL base unit 100. Thereby, the transfer of the first telephone directory data is completed. When the transfer of the first phone book data is completed, the transfer of the second phone book data is automatically started.

  In this way, the process G is repeatedly performed until the transfer of all designated telephone directory data (for example, 1-6000 cases) is completed.

<Cooperation control example 10>
Next, the flow of processing when an incoming call is received by the mobile phone 30a during transfer of the phone book data will be described with reference to FIG.

  In the middle of the process shown in FIG. 17, when an incoming call occurs in the mobile phone 30a that is transferring the phone book data (S1001), the incoming call information is transmitted from the mobile phone 30a by Bluetooth (registered trademark) communication, and the CDL parent The Bluetooth (registered trademark) communication I / F unit 124 of the device 100 notifies the HFP control unit of the Bluetooth (registered trademark) control unit 123 of the incoming bell (S1002). For example, when a mobile incoming call occurs in the mobile phone 30a that is transferring the phone book data (S1001), the Bluetooth (registered trademark) control unit 123 uses the incoming call information to call the wireless resource (high priority). The process of surrendering for the purpose is started.

  In FIG. 18, process A shows a process of surrendering radio resources for a call. In the process A, the HFP control unit first requests a resource request for a voice call to the BT radio control unit of the Middle layer according to the bell incoming notification sent from the Bluetooth (registered trademark) communication I / F unit 124. (S1003). The resource request in this case is a request for communication resources in the Talk mode between the CDL master device 100 and the mobile phone 30a (type = mobile phone 30a, mode = Talk). Upon receiving this resource request, the BT radio control unit starts processing for switching the Bluetooth (registered trademark) radio communication mode from the telephone directory transfer mode to the Talk mode, and notifies the HFP control unit of a resource response (S1004).

  Receiving the resource response notification, the HFP control unit starts the mobile incoming call sequence with the parent device control unit 109 in the CDL parent device 100, thereby notifying the parent device control unit 109 of the mobile incoming call in the mobile phone 30a. (S1005). Receiving this notification, base unit control section 109 controls ringing of the incoming call bell. By this control, ringing of the incoming call bell sound is started at the speaker of the CDL master device 100 (S1006).

  In FIG. 18, process H is a process of switching from the phone book transfer mode to the Talk mode and temporarily interrupting the transfer of the phone book data. Upon receiving the resource request, the BT radio control unit activates a process of switching the radio communication mode from the phone book transfer mode to the Talk mode and temporarily suspending the transfer of the phone book data.

  In FIG. 18, process H indicates a process for temporarily interrupting the transfer of the phone book data. In process H, first, the BT radio control unit notifies the AVRCP control unit of resource release, which means that the resource for the telephone directory transfer mode has been released (S1007). Receiving this notification, the AVRCP control unit sends a telephone directory suspension notification that means temporary suspension of the transfer of the telephone directory data to the PBAP control unit (S1008). Next, according to the notification, the PBAP control unit sends a telephone directory suspension notification to the base unit communication unit (S1009). Next, in accordance with the notification, the base unit communication unit sends a telephone directory suspension notification to the base unit control unit 109 of the CDL base unit 100 (S1010). Thereby, the transfer of the phone book data is temporarily interrupted (S1011).

  Through the above processing, the CDL master device 100 and the mobile phone 30a transition to the mobile call mode.

  In FIG. 18, after shifting to the portable incoming call mode, the process flow when the user performs an incoming call response operation is the same as the process shown in FIG. 10 (S502 to S508).

  Note that, when the incoming call information sent from the mobile phone 30a includes information related to the caller, the base unit control unit 109 of the CDL base unit 100 displays the information related to the caller on the display unit 106. Alternatively, base unit control unit 109 retrieves related information from the telephone directory database stored in storage unit 103 according to the information and displays it on display unit 106.

  In addition, when the base unit control unit 109 is notified of the mobile incoming call by the mobile incoming sequence (S1005), the mobile unit incoming call is also sent to the CDL slave unit 200 (for example, the CDL slave unit 200A) that can be connected to the base unit To be notified. In other words, a signal indicating that a mobile incoming call has occurred is transmitted by the DECT signal via the CDL wireless I / F unit 107. In accordance with the signal, the handset controller 147 of the CDL handset 200 controls ringing of the incoming call bell. By this control, ringing of the ringing bell sound is started at the speaker 152.

<Cooperation control example 11>
Next, the flow of processing when the user performs an operation to end a call during the temporary interruption of the transfer of the phone book data will be described with reference to FIGS. 19 and 20. When the user wishes to end the call, the call end operation is performed in the CDL master device 100 or one CDL slave device 200 that can be connected to the CDL master device 100.

  After the processing shown in FIG. 18 and FIG. 10, as shown in FIG. 19, when a call end operation is performed in the operation unit 105 of the CDL parent device 100 (S 1101), the parent device control unit 109 displays Bluetooth (registration). An instruction to terminate the call is sent to the trademark control unit 123 (S1102). Alternatively, when a call end operation is performed in a certain CDL slave unit 200 (S1101), a call end instruction is sent from the CDL slave unit 200 to the CDL master unit 100 by a DECT signal. The call termination instruction is transferred to the Bluetooth (registered trademark) control unit 123 (S1102).

  The call termination instruction sent from the parent device control unit 109 to the Bluetooth (registered trademark) control unit 123 is received by the parent device communication unit in the Bluetooth (registered trademark) control unit 123. Then, the base unit communication unit instructs the HFP control unit to end the call (S1103).

  In accordance with the call end instruction, the HFP control unit immediately instructs the Bluetooth (registered trademark) communication I / F unit 124 to send a call end signal (ATH) (S1104). Upon receiving this instruction, the Bluetooth (registered trademark) communication I / F unit 124 transmits a call end signal (ATH) to the mobile phone 30a where the mobile incoming call has occurred.

  In accordance with the call end signal (ATH), the mobile phone 30a performs a call end process and sends a call end response to the CDL master device 100. The Bluetooth (registered trademark) communication I / F unit 124 sends to the HFP control unit a call end response meaning that the process for ending the call has ended (S1105).

  In addition, the Bluetooth (registered trademark) communication I / F unit 124 sends a signal (voice link stop request) requesting stop of the voice link to the HFP control unit (S1106).

  Next, after stopping the voice link, the HFP control unit sends a signal (voice link stop response) indicating that the voice link stop request has been received to the Bluetooth (registered trademark) communication I / F unit 124 (S1107). ).

  In addition, the HFP control unit controls the BT voice control unit to finish forming the voice path for the call (S1108). Thereby, the formation of the two-way voice communication path is completed between the CDL master device 100 and the mobile phone 30a.

  Further, the HFP control unit requests the BT radio control unit to release the Talk mode resource (S1109). In accordance with this request, the BT wireless communication unit releases Talk mode resources.

  Next, the Bluetooth (registered trademark) communication I / F unit 124 sends a status notification (call nothing) received from the mobile phone 30a, which means that the connection with the other party (call partner) has ended, to the HFP control unit. (S1110).

  Next, the HFP control unit sends a status notification (call nothing) to the base unit communication unit (S1111). Next, the base unit communication unit sends a status notification (no call) to base unit control unit 109 (S1112). As a result, the cellular phone call mode ends, and the resumption of the transfer of the phone book data that was temporarily suspended is automatically started (regardless of the user's reproduction start operation) (S1113).

  That is, as shown in FIG. 20, the base unit control unit 109 in the CDL base unit 100 sends a phone book transfer resume request to the APP layer of the Bluetooth (registered trademark) control unit 123 of the CDL base unit 100 (S1114). .

  In accordance with the phone book transfer resumption request, the base station communication unit sends a phone book transfer resumption request to the PBAP control unit (S1115).

  Next, the PBAP control unit that has received the phone book transfer restart request makes a resource request to the BT wireless control unit in the Middle layer (S1116). The resource request in this case is a request for communication resources in the phone book transfer mode between the CDL master device 100 and the mobile phone 30a (type = phone book transfer a, mode = phone book transfer mode). Upon receiving this resource request, the BT radio control unit performs processing for switching the Bluetooth (registered trademark) radio communication mode from the Talk mode to the telephone directory transfer mode (S1117), and notifies the PBAP control unit of a resource response (S1118). .

  Next, the PBAP control unit sends a telephone directory transfer restart response to the base unit communication unit (S1119). Next, the base unit communication unit sends a telephone directory transfer restart response to base unit control unit 109 (S1120). As a result, transfer of the next telephone directory data is resumed, and processing G is performed (S1121). The next phone book data is phone book data transferred next to the phone book data (stored in the storage unit 103 of the CDL master device 100) transferred immediately before the temporary interruption. Note that the process G shown in FIG. 20 is the same as the process G (S913 to S918) shown in FIG.

  As described above, according to this linkage control example, when there is an incoming call to the mobile phone 30a during the transfer of the phone book data by the phone book transfer linkage, the transfer of the phone book data is temporarily interrupted, Transfer of phone book data can be resumed.

<Example 12 of cooperative control>
Next, the flow of processing when the user performs an operation of making a call to the mobile phone network 50 in the CDL device 1 during transfer of the phone book data will be described using FIG.

  After the processing shown in FIG. 17, when the user performs an operation of making a call to the mobile phone network 50 in the CDL master device 100 or the CDL slave device 200 that is transferring the phone book data (S1201), the CDL master device 100 The base unit control unit 109 sends a telephone directory transfer suspension request to the base unit communication unit of the Bluetooth (registered trademark) control unit 123 (S1202). Next, in accordance with the request, the base unit communication unit sends a telephone directory transfer suspension request to the PBAP control unit (S1203). As a result, processing for releasing the resource in the telephone directory transfer mode is started. When the CDL slave device 200 accepts a call operation to the mobile phone network 50 in S1201, the CDL master device 100 receives the information (signal) of the call operation from the CDL slave device 200 and receives music. A cooperation end notification is sent to the base unit communication unit of the Bluetooth (registered trademark) control unit 123 (S1202).

  Next, the PBAP control unit that has received the phone book transfer temporary stop request immediately issues a resource release request for releasing the phone book transfer mode resources to the BT radio control unit of the Middle layer (S1204). In accordance with this request, the BT radio control unit releases resources in the telephone directory transfer mode.

  Further, the PBAP control unit sends a telephone directory transfer temporary stop response to the base unit communication unit (S1205). In accordance with this response, the base unit communication unit sends a telephone directory transfer temporary stop response to base unit control unit 109 of CDL base unit 100 (S1206). Thereby, the transfer of the telephone directory data between the CDL master device 100 and the mobile phone 30a is temporarily suspended. That is, base unit control section 109 does not execute the process G data acquisition request transmission (S913) shown in FIG.

  Next, when the user inputs a calling number (for example, 123-456-7890) for calling the mobile phone network 50 in the CDL master device 100 or the CDL slave device 200 (S1207), the master device control unit of the CDL master device 100 109 transfers the calling number to the Bluetooth (registered trademark) control unit 123 (S1208 to S1209). Here, although it is assumed that the transmission number is input by the user in S1207, the transmission number may be input in S1201 during a transmission operation. In this case, base unit control unit 109 automatically transfers the calling number to the Bluetooth (registered trademark) control unit 123 (without user operation).

  Next, the HFP control unit of the Bluetooth (registered trademark) control unit 123 immediately makes a resource request for a voice call to the BT radio control unit of the Middle layer (S1210). The resource request in this case is a request for communication resources in the Talk mode between the CDL master device 100 and the mobile phone 30a (type = mobile phone 30a, mode = Talk). Upon receiving this resource request, the BT radio control unit starts a process of switching the Bluetooth (registered trademark) radio communication mode from the telephone directory transfer mode to the Talk mode, and notifies the HFP control unit of a resource response (ok) (S1211). ).

  Upon receiving the resource response notification, the HFP control unit starts a call activation sequence between the mobile phone 30a and the CDL master device 100. That is, the HFP control unit transmits the input transmission number (for example, 123-456-7890) to the mobile phone 30a via the Bluetooth (registered trademark) communication I / F unit 124 (S1212). In accordance with the transmission of the calling number, the mobile phone 30a starts a process of calling the mobile phone network 50 and transmits the calling number to the mobile phone network 50. Then, the cellular phone 30a sends a status notification signifying that it is being called to the CDL master device 100 (S1213).

  Then, when the mobile phone 30a enters a call state to the other party after transmitting the transmission number to the mobile phone network 50, the mobile phone 30a sends a signal (voice link request) for requesting voice link establishment to the CDL master device 100 ( S1214).

  Next, in accordance with the voice link request, the HFP control unit of the CDL base unit 100 starts control related to the connection activation between the CDL base unit 100 and the mobile phone 30a, and the Bluetooth (registered trademark) communication I / F unit 124. A voice link response is sent to the mobile phone 30a via S (S1215).

  Then, the HFP control unit controls the BT radio control unit to form a voice path for a call (S1216). Thereby, a two-way voice communication path is formed between the CDL master device 100 and the mobile phone 30a. However, at this stage, the mobile phone 30a transmits a call number to the mobile phone network 50 and makes a call to the other party (that is, the other party is not responding).

  Thereafter, the flow of processing when the calling party answers is the same as in FIG. That is, in FIG. 13, when the calling party responds and the communication path connection between the mobile phone 30a and the calling party is completed, the mobile phone 30a passes the Bluetooth (registered trademark) communication I / F unit 124 to the HFP control unit. A status notification (partner response) indicating a response is sent (S623). As a result, a voice call is started (S624), and a transition is made to a mobile call mode between the call partner and the CDL master device 100 (during a call). Thereafter, the process flow when the user performs an operation for terminating the call is the same as the process flow (S1101 to S1121) shown in FIGS. 19 and 20 described above.

  As described in connection control example 4 above, also in this connection control example, when a user makes a call using the CDL slave device 200, the user's voice is sent to the CDL master device 100, and the CDL master device 100 Is sent to the mobile phone 30a via the Bluetooth (registered trademark) communication I / F unit 124 by a voice path for a call. In addition, the voice of the other party of the call received by the mobile phone 30a is received by the Bluetooth (registered trademark) communication I / F unit 124 of the master unit, passes through the voice path for the call, and is sent from the CDL master unit 100 to the CDL. It is sent to handset 200 and can be heard as sound from speaker 152.

  With the above processing, an operation is performed to make a call to the mobile phone network 50 in the CDL master device 100 or the CDL slave device 200 while the phone book data is being transferred in the CDL master device 100 or the CDL slave device 200 of the cordless telephone device. In this case, the Bluetooth (registered trademark) control unit 123 of the CDL master device 100 immediately releases the radio resources and temporarily stops the transfer of the phone book data in conjunction with the outgoing call operation. Suspended. Then, since the radio resources for the call are re-acquired, the Bluetooth (registered trademark) control unit 123 can start calling the mobile phone 30 via the Bluetooth (registered trademark) communication I / F unit 124. .

  As described above, according to this cooperation control example, when a call operation to the mobile phone network is performed in the CDL master unit during the transfer of the phone book data by the phone book transfer cooperation, the transfer of the phone book data is temporarily performed. After the call is interrupted, the transfer of the phone book data can be resumed.

  In FIGS. 16 to 21, the phone book data is transferred from the mobile phone 30 a to the CDL master device 100, but the reverse is also possible. That is, even when the telephone directory data stored in the storage unit 103 of the CDL master device 100 is transferred to the storage unit 304 of the mobile phone 30a, the above-described cooperation control examples 9 to 12 can be realized.
