Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a telephone set that receives a call from another party during a telephone call.

Conventional technology In general, telephones that can receive a call from another party while on a call, such as Nippon Telegraph and Telephone Corporation's call waiting system, are used when the central office exchange notifies the telephone that this is the case, and the call is terminated by pressing a key. It is configured so that you can put the line on hold and talk to the other party.

Problems to be Solved by the Invention However, with the above-mentioned conventional telephone, if a call arrives from another party during a call, and the called party does not answer, it is difficult to know who the other party is. Therefore, there is a problem that, for example, an important business opportunity is missed because it is not possible to communicate with the other party.

SUMMARY OF THE INVENTION In view of the above-mentioned conventional problems, it is an object of the present invention to provide a telephone that can confirm the other party receiving a call during a call, and after the end of the call, can talk to another party.

Means for Solving the Problems In order to achieve the above object, the present invention stores the telephone number of the caller notified from the network, such as 15DN, when the telephone number is received during a call, and stores the telephone number after the call ends. This will make a call to that phone number.

Effect of the Invention With the above-described configuration, the present invention makes a call to the other party receiving a call during a call after the call ends, so that it is possible to talk to the other party.

EXAMPLES Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of a telephone according to the present invention;
FIG. 2 is a flowchart for explaining the operation of the telephone shown in FIG.

In FIG. 1, 10 is a network such as 15DN that notifies the called party of the caller's telephone number, 11 is a network interface that connects with the network 10, and 12 is a control system as shown in FIG. 13 is a random access memory (RAM) for storing data such as telephone numbers notified from the network 10; 14 is a central processing unit (CPU) for storing data such as telephone numbers notified from the network 10; This key switch is equipped with a setting key for automatically making a call, a setting key for making a call by key operation, and a key for making a call.

Note that a display indicating that a call has been received from another party during a call, and circuits necessary for the telephone, such as a dial sending circuit, a talking circuit, a handset, a hook switch, etc., are not shown.

Next, referring to FIG. 2, we will explain the operation of the above embodiment, especially the CPU.
The operation of No. 12 will be explained.

First, when a call arrives during standby, a line is established via the network 10 by the off-footer of the handset, and a call can be made.

In FIG. 2(a), when a call arrives from another party during this call, the network 10 notifies the telephone number of the other party in step 20), so the CPU 2 sends this telephone number to the network interface 11. The received call is received via the telephone and stored in the RAM 13 (step 21), and the display unit displays that a call has arrived from another party during the call (step 22), and this routine ends (step 22).

If the key switch 14 is set to automatically call the other party who received the call during the call after the call ends, the handset is turned on-hook as shown in FIG. 2(b) (step 30). The telephone number stored in step 21 is read (step 31), and the dial sending means is controlled to send a dial signal corresponding to this telephone number (step 32).

Therefore, according to the above embodiment, when a call arrives from another party during a call, the other party is automatically called after the call ends, and the conversation becomes possible when the other party answers.

On the other hand, if the key switch 14 is set to make a call to the other party who received a call during the call after the call ends, as shown in FIG. 2(C), the call will be made after the call ends. When the key is operated (step 40
), reads the telephone number stored in step 21 (step 41), and controls the dial sending means to send a dial signal corresponding to this telephone number (step 42).

Therefore, according to the above embodiment, when a call arrives from another party during a call, the other party is called by operating the call key after the call ends, and the call can be started when the other party answers. become.

As described in detail, the present invention stores the caller's phone number notified from the network during a call, such as 15DN, and makes a call to the phone number after the call ends. Now, you can talk to the other party who received the call during the call.
