Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a calling party telephone number transmission system using telephone circuit switching technology, data communication technology, and microcomputer application technology.

[Background Art 1 Conventionally, in exchanges that control incoming and outgoing calls on telephone lines and control line connections, when performing reverse detection in which the called party attempts to learn the telephone number of the calling party, the line connection control is performed from the called party to the calling party. This requires a considerable amount of time and effort, and there is the problem that the person receiving the call cannot easily find out the caller's phone number on the spot. Ta.

[Object of the Invention] The present invention has been provided in view of the above-mentioned points, and is provided with a means for storing and transmitting the telephone number of the calling party in the exchange, and a means for receiving the telephone number transmitted to the telephone on the terminal side. Moreover, by providing a means for displaying the information, there is provided a telephone number transmission system for the calling party, which is intended to enable the called party to easily recognize the telephone number of the calling party.

[Disclosure of invention] Embodiments of the present invention will be described below with reference to the drawings.

As shown in FIGS. 1 and 4, each subscriber telephone 1 is connected to an exchange 4, and the exchange 4 generally connects the originating telephone
Dial pulse or P sent from l I A
Identifying the destination selection signal of the B-fold signal, the originating telephone 11
The line α between 1A and the called side telephone IB is connected, a ringing signal is sent to the called side, and the line e is closed. FIG. 4 shows a so-called complaint correspondence diagram, and the exchange 4 includes a storage means 5 for storing the telephone number sent from the calling side telephone IA, and a transmitting means for transmitting the telephone number stored in the called side telephone RI B. 6. Calling party phone I
B is equipped with reception display means 3 for receiving a telephone number transmitted from exchange 8!4 and displaying the telephone number when the telephone number is answered after receiving a calling signal from exchange P114.

Next, it will be explained in detail. The exchange 4 receives the dial pulse or PB from the calling telephone filA as shown in
Dial pulse analysis section 7 and P that receives and analyzes the double signal

It has a subscriber telephone network control section 11 consisting of a circuit switching connection side m section 10 for connecting. Also, the calling party phone f
The calling gA is a storage means 5 for storing the phone number of ilA.
74 talk number memory 12, a calling side phone number display section 16 that displays the phone number of the calling side phone 1A, and a phone number stored in the calling side phone number memory 12 on the called side phone filB.
The transmitting unit 6 is a transmitting means 6 that transmits data via the i-side telephone number transmitting unit 13 and the calling-side telephone number control unit 14.
is provided in the exchange 4. Further, the central control unit 15 monitors and controls the operation of the entire exchange 4. Is Figure 2 a member? This shows the structure of the IT network, which is divided into four levels of telephone stations: 1) General office, 2) Central office, 2) Centralized office, and 2) Terminal office. The exchange 4 of the terminal office that accommodates the subscriber telephone 1 determines which subscriber telephone fil is in the outgoing state by looking at the connection contacts of the exchange 4, and determines which subscriber telephone fil is in the outgoing state by checking the connection contacts of the exchange 4. The telephone number is stored in the memory 12. Further, the calling side telephone number transmitting section 13 of the exchange 4 performs data communication using the FSK method by using, for example, a modem (modulator/demodulator FIT).

Next, as an example, the operation 70- of making a call from the calling side telephone IA of the subscriber telephone 1 to the called side telephone 611B and transmitting the calling side's telephone number to the called side is performed as 70 of the operation of the exchange 4 in FIG.
-Char). First, the calling party phone IIA
causes a calling operation.

When the selection signal is sent, the terminal exchange 4 sends a dial tone to the originating telephone filA, and also analyzes the selection signal to identify the called party's telephone number. At the same time, the exchange 4 stores the telephone number of the calling party's phone Wi I A. 5. Next, if the called party's telephone number is not the telephone number of a telephone connected to the same terminal station B as the calling party's, the exchange 4 Connect the line to station C and send the phone number to call. In this way, while decoding the telephone numbers sent from each telephone office, the lines between the telephone stations are closed in the order of terminal station B, central station C, central station D, central station E, and iMF. The called telephone filB of the subscriber telephone 1 is selected at F, and the line from the calling telephone IA to the called telephone IB is connected.The exchange 4 sends a ring tone to the calling telephone bill IA, X1 Calling side telephone IB
When the called party telephone Wl I B answers the call number 13, the ring tone,
The sending of the ringing signal is stopped, and the calling party's telephone, which has been stored in terminal station B, uses the communication path B-C-e that has opened the IA's telephone number.
It is transmitted to terminal station F through D- and E-F. The terminal station F stores the sent telephone number of the calling party and transmits it to the subscriber telephone 1 (the receiving telephone IB).The receiving telephone IB receives the telephone number of the calling party on the reception display means 3. and display the calling party's telephone number. Therefore, the called party can recognize the telephone number of the calling party. In addition, if you look at the calling side telephone number display section 16 provided for each subscriber telephone 1 at the terminal station F, each subscriber telephone 811
The phone number of the caller can be recognized. In addition, the subscriber telephone 1 has a data reception function and a display 8+.
If this function is added, the calling party's telephone number can be easily and immediately obtained from the subscriber's telephone. Incidentally, when the exchange 4 connects the line to the called party, if the called party is busy, a busy tone is sent to the calling party to notify the calling party that the calling party is busy.

[Effects of the Invention] As described above, the present invention receives a signal for calling the called party from the calling party's telephone, searches for the calling party, connects the line, and sends the caller's telephone to the exchange that connects the line and calls the called party. A storage means for storing the number and a transmission means for transmitting each telephone number stored in the storage means to the called party are attached, and when the telephone number is received and answered from the exchange, the telephone number is transmitted from the exchange n. This device is equipped with a reception display means for receiving and displaying the telephone number of the calling party, which allows the receiving party to easily know the telephone number of the calling party and prevent threatening calls. This makes it possible to quickly find out the address, name, etc. of the caller of a nuisance call or a nuisance call, which helps prevent unauthorized use of the phone.It also allows the caller's phone number to be displayed instead of in the call.
