The wireless hands-free device 2 has not only a normal call function for making a call via the telephone 1, but also a new incoming number redial function that allows a user to redo the call with a simple touch operation.

  FIG. 1 shows a configuration example of a call redial system using a wireless hands-free device 2. The wireless hands-free device 2 is communicably connected to the Bluetooth compatible phone 1 via a wireless link, and the hands-free communication device 10 is configured by the phone 1 and the wireless hands-free device 2.

  In addition, as the telephone 1, as long as it is wirelessly linked to the wireless hands-free device 2 at a short distance, not only a fixed telephone but also an in-vehicle mobile telephone can be applied. For example, Bluetooth in-vehicle devices that assist hands-free calls while driving a car are used.

The wireless hands-free device 2 is equipped with a call redial function and has an internal memory 3 for storing the telephone number of the partner P when a call is received from the partner P. The incoming call is determined by the processing unit 11, and the incoming call number is automatically stored and saved in the memory 3 at the same time as the ringing tone is generated (see FIG. 2). On the surface of the wireless hands-free device 2, a dedicated incoming redial operation button 5 or an operation key for making a call to a telephone number stored in the internal memory unit 3 is provided.

  If there is an incoming call from the other party P, it is determined in step S2 that “there is an incoming call”. However, if the user U does not answer the call, the “incoming redial” is executed in step S3 unless the user U makes another call later. Since the “on operation of the operation button” is not determined, the process returns to the first incoming call waiting state. Further, when making a call using the latest stored and stored telephone number, the incoming call redial operation button 5 may be pressed. This redial transmission operation can be executed at any time regardless of the result of the incoming call determination.

  As described above, when there is an incoming call from the other party P to the telephone U of the user U, the incoming number of the other party P is stored in the internal memory unit 3. Then, when the user U cannot answer the call due to circumstances, he / she stores in the internal memory unit 3 via the telephone 1 by activating the Bluetooth communication unit 4 with the incoming call redial operation button 5 when he / she calls again. Is sent by the telephone number of the other party P.

  Thus, for example, if the user U cannot answer the call, the incoming call redial operation button 5 can be called again to the other party P on the wireless hands-free device 2 side. There is no need to type in the telephone 1, and the convenience of using the hands-free call device is remarkably improved.

Further, the display number 6 of the wireless hands-free device 2 displays the incoming call number of the other party P who has called, so that the user U can identify who the other party P has called. Easy to confirm. For this reason, after confirming the partner P, it is possible to immediately determine whether to answer the call immediately or to call again later.

  Further, even when calls are received from a plurality of opponents P, all incoming numbers are stored in the memory unit 3 and these incoming numbers are displayed and searched by the display screen unit 6 of the wireless hands-free device 2. Therefore, the user U can select the incoming call number to be redialed from a plurality of incoming call numbers displayed on the display screen unit 6 and determine the order to redial.

  In particular, when the telephone 1 is an in-vehicle telephone, if there is an incoming call while driving a car, depending on the traffic conditions, etc., avoid telephone calls on busy roads and move to a quiet place later. You can redial the incoming number in the car.

  Further, when the wireless hands-free device 2 is wirelessly connected to a plurality of telephones 1, a plurality of users U can perform an incoming redial operation with one wireless hands-free device 2.

  Further, since the incoming call history data stored in the memory unit 3 can be searched, it is possible to specify later who used the hands-free call device 10. In particular, if the car equipped with the hands-free call device 10 is owned by the company, whether each user U used the hands-free call device 10 for personal use or for business purposes. It is easy to know.

  In addition, the incoming history data stored in the memory unit 3 of the wireless hands-free device 2 is copied to the personal computer of the user U by connecting the wireless hands-free device 2 to the personal computer of the user U with a USB cable or the like. It is also possible to capture, save and use, and store and manage incoming numbers at home. In addition, the telephone number stored in the personal computer can be pre-registered in the wireless hands-free device 2, and the convenience of using the wireless hands-free device 2 is significantly improved.
