In the case of the first embodiment, the Bluetooth master unit 15 is adapted to send and receive voice data not by a voice profile but by an audio profile, whereby a broadband between the subscriber premises apparatus 10 and the radio telephone terminal 20 is obtained. Voice communication is possible. The Bluetooth master unit 15 exchanges control data with the radio telephone terminal 20 using a profile different from the audio profile for audio data. That is, the Bluetooth master unit 15 and the Bluetooth slave unit 21 described later can discriminate whether the communication data is audio data or control data based on the difference in profile.

  In the subscriber premises apparatus 10, the Bluetooth master unit 15 exchanges control data with the CPU unit 12 and exchanges voice data with the VoIP processing unit 14.

  The radio telephone terminal 20 includes a Bluetooth slave unit 21, an A / D / D / A mutual conversion unit 22, a speaker 23, a microphone 24, a CPU unit 25, a keypad unit 26, and a ringer unit 27.

  The Bluetooth slave unit 21 is provided as a wireless communication unit, and wirelessly communicates voice data and control data through a cooperative operation with the above-described Bluetooth master unit 15 in the subscriber premises device 10. The Bluetooth slave unit 21 transmits the audio data given from the A / D / D / A mutual conversion unit 22 and the control data given from the CPU unit 25, and the received audio data is converted into the A / D / D / A mutual data. This is given to the conversion unit 22 and the received control data is given to the CPU unit 25.

  The speaker 23 generates and outputs the received voice from the partner terminal, and the microphone 24 captures the user's transmitted voice. Here, the speaker 23 and the microphone 24 are of high quality capable of handling a wideband audio signal. The speaker 23 and the microphone 24 may be incorporated in the casing of the radio telephone terminal 20, or constitute a handset or a headset and connected to the main body of the radio telephone terminal 20 by a cable.

If the operation key is a numeric keypad, the CPU unit 25 displays the operation data on the display. If the LED is related to the function having the LED, the LED is controlled to be turned on, blinked, and turned off. Further, for example, when the ringer ring control data is given from the Bluetooth slave unit 21, the CPU section 25 controls the ringer section 27 to ring.

(A-2) Operation of the First Embodiment Hereinafter, operations of the home telephone communication system 1 of the first embodiment will be described with respect to a radio link establishment operation, a transmission operation, an incoming operation, and a disconnection operation.

  First, the radio link establishment operation will be described. When the power-on wireless telephone terminal 20 enters within the communicable distance of the Bluetooth master unit 15 of the subscriber premises device 10, or is located within the communicable distance of the Bluetooth master unit 15 of the subscriber premises device 10. When the power-off wireless telephone terminal 20 is turned on, the Bluetooth device master unit 15 and the Bluetooth slave unit 21 perform communication according to a general Bluetooth method for establishing a link, and the subscriber home device 10 and A wireless link between the wireless telephone terminals 20 is established.

  Next, a transmission operation will be described. The transmission operation is premised on the state of establishment of the wireless link between the subscriber premises apparatus 10 and the wireless telephone terminal 20 described above.

  The user operates the send key after inputting the other party's telephone number to the keypad unit 26. Each time a key is input, the CPU 25 causes control data representing the key to be wirelessly transmitted from the Bluetooth slave unit 21. The Bluetooth master unit 15 sequentially gives control data representing the received operation keys to the CPU unit 12. The control data from the Bluetooth slave unit 21 is the same as the control data from a subscriber circuit (SLIC; not shown) in a conventional subscriber premises apparatus accommodating an analog telephone.

  When the CPU unit 12 receives the control data representing the other party telephone number and the transmission key, the CPU unit 12 cooperates with the VoIP processing unit 14 to form a control packet for connection request and transmit it from the network interface unit 11 to the IP network side. The Bluetooth master unit 15 wirelessly transmits control data indicating connection request acceptance. The Bluetooth slave unit 21 gives the received control data to the CPU unit 25. Since the received control data is control data indicating acceptance of a connection request, the ringer unit 27 sounds a tone indicating that. .

  In response to the transmission of the connection request control packet, the network interface unit 11 eventually reaches a response control packet indicating that the call is busy or busy.

  The network interface unit 11 provides the received response control packet to the CPU unit 12, and the CPU unit 12 cooperates with the VoIP processing unit 14 to transmit a control packet for receiving a response control packet from the network interface unit 11 to the IP network side. And the response control packet is analyzed.

  When the response control packet is busy, the CPU unit 12 gives control data to that effect to the CPU unit 25 of the radio telephone terminal 20 through communication between the Bluetooth master unit 15 and the Bluetooth slave unit 21 to generate a busy tone. Ringing is performed by the ringer unit 27, and when the CPU unit 25 recognizes the user's operation of the off-hook key, the ringing of the tone is also terminated. Note that the busy tone may be generated by the subscriber premises apparatus 10 (the VoIP processing unit 14 thereof) and given to the radio telephone terminal 20 (the ringing back tone is the same).

  On the other hand, when the response control packet is ringing, the CPU unit 12 gives control data to that effect to the CPU unit 25 of the radio telephone terminal 20 through communication between the Bluetooth master unit 15 and the Bluetooth slave unit 21, and the CPU The unit 25 causes the ringer unit 27 to ring the ringing back tone.

  When the user of the partner terminal goes off-hook, a control packet to that effect arrives from the IP network side, and the network interface unit 11 receives and gives it to the CPU unit 12. The CPU unit 12 cooperates with the VoIP processing unit 14 to transmit the control packet of the reception acknowledgment of the control packet from the network interface unit 11 to the IP network side, and recognizes that the other party has received an incoming call response by the control packet. .

The Bluetooth master unit 15 transmits the received voice data to the VoIP processing unit 14. The audio data at the stage output from the A / D / D / A mutual conversion unit 22 and the audio data output from the Bluetooth master unit 15 are the same (the same applies to the reverse direction). The VoIP processing unit 14 assembles a voice packet from the received voice data, and sends it out to the IP network side via the CPU unit 12 and the network interface unit 11 sequentially. Note that the VoIP processing unit 14 may perform all of the VoIP control processing such as assignment of voice packet sequence numbers and insertion of IP addresses, and the CPU unit 12 may perform part of the control processing.

  The voice packet received from the IP network side by the network interface unit 11 is given to the VoIP processing unit 14 via the CPU unit 12, and is subjected to packet decomposition to restore the voice data. The voice data is transferred from the Bluetooth master unit 15. Wirelessly transmitted. The Bluetooth slave unit 21 that has received the audio data gives the received audio data to the A / D / D / A mutual conversion unit 22 to convert it into an analog audio signal, and outputs the sound from the speaker 23.

  Next, the incoming call operation will be described. The incoming call operation is also premised on the state of establishment of the wireless link between the subscriber premises apparatus 10 and the wireless telephone terminal 20 described above.

  When a connection request control packet arrives from the IP network side, the network interface unit 11 receives the packet and gives it to the CPU unit 12. At this time, the CPU unit 12 cooperates with the VoIP processing unit 14 to transmit a control packet for receiving a connection request control packet from the network interface unit 11 to the IP network side, and also transmits connection request reception control data to the Bluetooth master. Wireless transmission from the unit 15. The CPU unit 25 to which the connection request reception control data is given from the Bluetooth slave unit 21 causes the ringer unit 27 to ring a ringing tone (in addition, there is a configuration that vibrates when an incoming call is received. Vibrate).

  When the user operates the off-hook key of the keypad unit 27, the CPU unit 25 stops the ringing tone and makes the A / D / D / A mutual conversion unit 22 operable, for example. In addition to performing time control, the communication data between the Bluetooth slave unit 21 and the Bluetooth master unit 15 is provided to the CPU unit 12 of the subscriber premises device 10 by receiving control data for incoming call response. The CPU unit 12 cooperates with the VoIP processing unit 14 to internally set the inside of the VoIP processing unit 14 in a state in which voice data can be processed, and to transmit an incoming response control packet from the network interface unit 11 to the IP network side. , Form a call path.

  In the call state, the user operates the on-hook key of the keypad unit 26 to end the call process. At this time, the CPU unit 25 performs control such as setting the A / D / D / A mutual conversion unit 22 to a standby state and the like, and indicates control indicating disconnection by communication between the Bluetooth slave unit 21 and the Bluetooth master unit 15. Data is given to the CPU unit 12 of the subscriber premises apparatus 10.
