Abstract

PURPOSE:To enable the terminating side to select an originating subscriber by inputting the originating subscriber's telephone number, which is transmitted through a telephone line, to a CPU through a control signal receiving circuit and emitting a ringing tone if this telephone number coincides with a telephone number in a memory as the result of comparison. CONSTITUTION:Telephone numbers of subscribers from which calls should be terminated are preliminarily stored in a memory 8 as automatic dialing telephone numbers. A CPU 4 has a function to compare the telephone number of the other party detected and the incoming time (originating subscriber's telephone number) with all automatic dialing telephone numbers stored in the memory 8. If one of automatic dialing telephone numbers stored in the memory 8 coincides with the originating subscriber's telephone number, the CPU 4 displays the originating subscriber's telephone number of a display device 5. Simultaneously, a ringing tone generator 7 is driven by a ringing tone control circuit 6 to emit the ringing tone.

Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to an automatic dialing telephone that allows selection of incoming calls.

(c4. Prior Art) Various types of telephones have been devised to notify the called party of the caller's telephone number in the existing analog telephone network or extension telephone (see Japanese Unexamined Patent Publication No. 121863/1983).0 In the case of these telephones , which only displays the caller's phone number along with the ringtone, cannot be said to be an effective means from the perspective of preventing phone calls. Even in digital/I'm telephones provided by information communication systems,
It only displays the caller ID and does not allow you to select whether to receive a call.

(c) Problems to be solved by the invention As described above, with conventional telephones, when making a call, you can select a specific party, but when receiving a call, the ring tone sounds unconditionally, so you cannot answer any caller. ◎As a result, prank calls and other calls have recently become a problem because the called party cannot select the caller.□The present invention also provides the called party with an automatic dialing function the ability to select the caller. The present invention has an automatic dialing function that sends out a dialing signal by calling a telephone number stored in a memory. In the automatic dial /I/ packing machine, the telephone number for automatic dialing is stored in the memory connected to the CPU, and the control signal receiving circuit receives the caller's telephone number sent via the telephone line. The telephone number is input to the CPU via the telephone number and compared with the telephone number in the memory. If they match, the ring tone control circuit drives the ring tone generator to generate a ring tone and select the caller.

(The phone number for automatic dialing is stored in advance in the operating memory, and the CPU compares the sent caller's telephone number with the telephone number for automatic dialing, so the ring tone generator is activated only if they match.) It can be activated to generate a ring tone, and the receiving party can select the caller.

(v) Embodiment The figure is a block diagram showing the configuration of a digital telephone according to an embodiment of the present invention. ◎The digital telephone is installed in the INS digital communication network, and voice signals are converted into digital signals and control signals. In the figure, (1) is a transmitting/receiving amplifier, (2) is a demultiplexing circuit that performs modulation/demodulation and multiplexing of control signals and audio information, +3+ is a control signal transmitting/receiving circuit, and (4) is a time multiplexed transmission/reception circuit. A CPU that controls the entire telephone, (51 is a display, +61 is a ring tone control circuit, (7+ is a ring tone generator, (8) is a memory that stores multiple telephone numbers, (91 is a dial button,
Oe is an AD converter, συ is a DA converter, α2 is a receiver,
a3 is a transmitter, α41 is a hook switch, α51 is a reception line, and 161 is a transmission line, each of which constitutes a detailed transmission line for reception and transmission. The J-181VC stores a large number of telephone numbers in advance, and the telephone is configured to have an automatic dialing function (one-touch automatic dialing function - 29 and return dialing function) that allows dialing with simple operations. Memo on your phone like this! A telephone number for automatic dialing is stored (registered) in the J-18+, and a caller is selected based on this telephone number as described later.Next, the signal flow of the present invention will be explained. The signal input from the receiving line (151) of the telephone line is sent to the transmitting/receiving amplifier (151).
The signal is amplified and shaped at step 1, and the control signal and audio signal are separated at demultiplexer circuit +21. The audio signal is sent to the DA converter alJ
It is converted into an analog signal by the VC and output from the receiver α.

The audio signal input to the transmitter α3 is converted into a digital signal by the push button of the AD conversion converter. This digital signal is time-multiplexed with the control signal by the demultiplexing circuit 121, and is transmitted through the transmitter/receiver amplifier 7't1+. line [161
sent to.

On the other hand, the t reception control signal separated by the demultiplexing circuit +21 is converted into an appropriate r-mapto by the control signal reception circuit 13+, and is input to CP[JIJ. In the INS digital communication network, when a call is received, the caller's telephone number is sent as a type of control signal. Therefore, CPU +4
1 is able to detect the caller's phone number when receiving a call.As mentioned above, you can write down the phone number(s) of the person you want to accept the call in advance! J-tel is stored as a telephone number for automatic dialing (for one-touch automatic dialing or flexible dialing), and is also stored on the CPU14+.
Ifx, note the phone number of the other party detected when receiving a call (caller phone number)! It has a function to compare all the automatic dialing telephone numbers stored in J-181. 1
If one of the automatic dialing telephone numbers stored in the memory (81) matches the caller's telephone number, the CPU (4) displays the caller's telephone number on the display 15+.
At the same time, the ring tone generator 17+ is driven by the ring tone control circuit +67 to generate a ring tone.

Detects when a call arrives and notes the next caller's phone number! J-(8J
If none of the automatic dialing telephone numbers stored in the automatic dialing telephone numbers match, a control signal to reject the incoming call is sent to the transmission line via the transmitting/receiving amplifier, and no ringing tone is generated.

In this case, the caller telephone number is displayed on the display f5+, and the ring tone control circuit (61: 9 ring tone generator 17
1't-drive to generate a ring tone by lowering the volume or changing the tone color, it is possible to distinguish whether the caller is from a party whose automatic dialing telephone number is registered or not.

In this way, by only accepting incoming calls from parties with pre-registered and auto-dial phone numbers, it is effective in preventing phone calls, which have recently become a problem. However, it goes without saying that the same function can be achieved by using a DTMF signal as a control signal.

In this way, with automatic dialing telephones, you can save memory capacity by registering the telephone number for automatic dialing (one-touch automatic dialing is for speed dialing) and using the telephone number as it is for selective incoming calls. (Since the person who accepts incoming calls is usually the person you call frequently, it is okay to use the same memory for automatic dialing and selective incoming calls, -1
) If you register a telephone number for automatic dialing, you can use it for selective incoming calls, so there is no need to take the trouble to remember the telephone number for selective incoming calls, which is extremely convenient in practice.

(G) As described in detail, according to the present invention, when a call is received from a person other than the person who has registered the telephone number for automatic dialing in advance, the incoming call can be rejected or the volume of the ring tone can be changed. This gives the receiving party the ability to select the caller, which is very effective in preventing phone calls. In addition to saving memory capacity, there is no need to bother with remembering a telephone number for selective incoming calls, which is extremely convenient in practice.
