The communication management unit (18) also instructs the layer 1 processing unit (15), layer 2 processing unit (16), and layer 3 processing unit (17) to make a call using the dial information as the destination number,
Send an outgoing signal on the D channel (12). The receiving side performs the same process as the above-mentioned operation upon receiving a call, and if a response is received, the call goes into a one-call state.

Furthermore, a case will be described in which a call is made from the originating side to the called party (9) after the outgoing call from the telephone (1) is completed. Pick up the handset (2) and
0) is pressed, the key control unit (8) senses this and notifies the communication management unit (18) that there has been a request for a re-call from the calling party to the receiving party.

In the communication management section (18), there is a calling party number storage section (19).
The D-channel (12) Send an outgoing signal to the top.

[Problem to be solved by the invention]

Conventional devices are configured as described above, so when the calling party wants to call back from the calling party after the outgoing call ends, the user only has to press the outgoing redial key; When the called party calls back to the calling party after the call is completed.

Users must write down the caller's number displayed on the display, or ask the caller for the number directly and write it down during the call, and use a keypad to call back. There was a problem in that it required the user to dial the other party's number, forcing the user to perform a complicated process.

This invention was made to solve the above-mentioned problems, and even when the called party calls back to the calling party after two incoming calls are completed, the call can be made by pressing just one key. The aim is to obtain a device that can be repaired and does not require dialing using a keypad.

[Means to solve the problem]

The communication device according to the present invention utilizes the calling number display among the additional services provided by the 15DN, and is provided with a receiving party number storage unit that stores the calling number when the second call is received, and retrieves this stored information when making the second call. A means is provided for making a call using this information as the other party's number.

[Effect]

The communication device according to the present invention stores the calling number when receiving a 9 call.

When making a safe call, the memorized information is retrieved and the call is made using that information as the number of the other party, so the user does not have to memorize or search the number of the other party, or dial using a keypad. (be able to.

do. (1) to (20) are the same as those in FIG. 2, and therefore will be omitted. (21) is an incoming call number storage unit that stores the calling number when an incoming call is received, and (22) is an incoming call redial number storage unit that is used when making a call with the number stored in (21) as the other party number. be.

The operation will be explained based on FIG.

First, we will discuss the case of one incoming call. Incoming signal is l5DN
It is transmitted from the subscriber line (9) via the network termination device (10) onto the D channel (12). Telephone (1) is.

When an incoming signal is received through the electrical level termination section (13), a layer 1 processing section (15) and a layer 2 processing section (16) are received.
) The layer 3 processing unit (17) and the communication management unit (18) return a response in accordance with the SDN communication procedure to the other party, and a ring is sounded from some speakers (5), and one incoming call is received. Inform the user. At the same time, the communication management department (
18) displays the calling party number on the display section (6), and further stores the calling party's number in the receiving party's number storage section (21) at the time of second incoming call. The subsequent operations are the same as those of the conventional example, and will therefore be omitted.

Next, a case will be described in which the called party calls back to the calling party after the call that has arrived at the telephone (1) ends. When the user picks up the handset (2) and presses the incoming call redial button (22), the key control unit (8) senses this and informs the communication management unit that there is a request from the called party to call back. (18) Notify. Communication Management Department (
In 18), the layer 1 processing unit (15) and layer 2 processing unit (16) extract information stored in the destination number storage unit (21) when a call is received, and send a call using that information as the destination number. , to the layer 3 processing unit (17) and send out a transmission signal on the D channel (12).

Note that the operations at the time of outgoing calls, other than the case where the called party calls back to the outgoing party after the end of one incoming call, are the same as in the conventional example, and will therefore be omitted.

Incidentally, in the above embodiment, 1 number storage section and dial keys are provided separately for 2 for outgoing calls and for incoming calls. However, if the configuration shown in Fig. 2 is maintained, the calling party's number is stored in the calling party's number storage section (J9) even when a call is received, and the calling party's redial key (20) is used when the called party calls back from the receiving party to the calling party.
Press . The same effect can be obtained even if the number storage section and the dial key are the same for both the outgoing call and the incoming call.

Further, in the above embodiment, an example in which one number is stored is shown, but it is also possible to store multiple numbers and select one to make one call, and the same effect can be obtained.

〔Effect of the invention〕

As described above, according to the present invention, the calling party's number is memorized at the time of an incoming call by using the calling number display, which is an additional service of l5DN, and the memorized information can be saved by the user simply pressing a single key. Take it out and make a call using that information as the other party's number, so when you call back from the receiving party to the calling party after the incoming call ends, make a note of the calling number.
This eliminates the trouble of dialing using a keypad and allows you to make a new call by simply pressing a single key.
