Description

DETAILED DESCRIPTION OF THE INVENTION (Field of the Invention) The present invention provides an I! 1-riru.

(Background of the Invention) As is well known, in the current public telephone network, a call cannot be made until the called party picks up the telephone in response to the telephone ringing (referred to as off-knock) and interacts with the caller. person
It is not possible to know in advance who is calling. In data communication and facsimile, the code of the calling party is automatically transmitted to the other party, but in this case, the ID code is also transmitted after the line is established between the calling party and the called party. It is not particularly different from the public telephone line network mentioned above.

This is one aspect of phone calls that makes them happy, but on the other hand, it's a prank call, @Gara゛I! This has led to telephones being used for anti-social purposes, such as criminal use.

For public use of these telephones, (1) Restriction of incoming calls by dual number system of general number and secret number;
Countermeasures have been adopted such as 2) incoming call restrictions that only accept incoming calls from specific callers at night or at specific times, and (3) reverse caller ID search services that are performed at the request of the police in the case of crimes, etc. has been done.

However, the incoming call restriction (1) is of no use if the secret number is known, and there is also the problem that emergency calls cannot be received from people who do not know the secret number.

The 6-channel restriction (2) makes it impossible to receive truly necessary communications from anyone other than a specific caller. (3) Reverse detection takes too much time and procedures, and is ineffective against pheasant calls that only ring and immediately hang up.

At present, no effective countermeasures have been found against anti-church phone use that is carried out with malicious intent.

(Object of the Invention) In view of the above-mentioned conventional problems, the inventors of the present invention have devised an object to effectively deal with the use of telephones for malicious and anti-social purposes without completely impairing the effectiveness of telephones. We have developed a telephone exchange system that can The system transmits the calling party number to the called party prior to the ringing signal.

An object of the present invention is to provide a telephone set that is connected to the switching system with a caller ID notification function and that allows the user to know the number of the caller before picking up the handset.

(Structure and Effect of the Invention) In order to achieve the above object, the present invention provides a telephone for use in a switching system with a calling party ID notification function that transmits the calling party's number to the called party prior to a paging signal. The present invention is characterized in that it includes means for receiving the calling party number and means for displaying the received calling party number.

With this telephone, it is possible to know the number of the caller before picking up the handset, and after seeing the number, the user can answer the call or reject the call.

As a result, the use of telephones for anti-social purposes, such as pranks and harassment9 crimes that take advantage of the anonymity of telephone calls, will be significantly restricted, and moreover, the original effectiveness of telephone calls will be almost completely jeopardized. do not have.

Here, the provision of the incoming caller ID trunk F<ST is a hardware feature of this system that is different from the conventional system. This system consists of the addition of a circuit called the incoming caller ID trunk R8, and the related main control software (control sequence) for the CPU.
This is achieved by changing the . Each of the above components other than the incoming caller ID trunk R3T is well known, and the basic control sequence of the telephone exchange is also well known. Below, we will mainly explain the features of this system.

Subscribers who receive the "calling name number notification service" related to this invention are registered in advance, and registration data to that effect is stored in the external memory 83. In addition, subscribers who receive this service will be able to make calls [L@] below.

- [The operations of the recording/reconciliation system will be summarized in several parts and explained in turn according to each control sequence.

A: When a call is made or received within the own station, and the called subscriber has not registered for the calling party ID service (in other words, it is exactly the same as a conventional telephone exchange), the control sequence in this case is shown in 2A. Shown in the figure.

(1) When the person making the call puts the handset on the A-hook, the main controller CPU detects the call based on the monitoring status of the subscriber line scanning device LSCN, and connects the line link network 1-LN.

From now on, send a dial tone to the dial register trunk OR
T4 becomes ready to receive Daicel information from the calling telephone 1i''rEL.

(3) The main control unit @ CPU receives the dial signal via the outgoing register ORT and judges it. When the first pulse is received, the transmission of the beep is stopped by setting the relay drive RC to Wb. When the time cell signal is received, it is sequentially stored in the reception number area in the memory area for transmission register 1-rank ORT.

(4) When the reception of the dial signal by the originating register trunk OR1- is completed, the main control unit CPU stores information such as the memory for the originating register trunk 0RI-, the called subscriber number 1 in the area, and the calling subscriber number. Analyze incoming calls based on. If the call is outside the local station, the process moves to relay processing.

(5) If the call originates from or arrives at your own station, further analysis of the incoming call (no,
Check whether the called subscriber has registered for Caller Registration Number Notification 1 Novice. When you have not registered the calling party ID service, this is the same as the conventional method,
~Rank I01', Ring tone 1~Rank RBT, check for empty ring signal trunk RGT.

(6) When all lines are empty, make a call; 111 person line has ring tone trunk R instead of call register trunk ORT.
Connect B'T and send a ring tone to the calling telephone to notify the other party that the other party is being called. at the same time,? 1! A ringing signal trunk RG1 is connected to the calling subscriber's line, and a ringing signal is transmitted to the called telephone via it, and the bell is rung to notify the incoming call. Thereafter, the trunk scanning device 1'SCN monitors the response of the called telephone I through the calling trunk RGT.

(7) When it is detected through the trunk scanning device T S CN that the called telephone is off-hook, the main controller C
The PU connects both the calling subscriber line and the called subscriber line using the 1-rank IOT within its own station, and connects the calling party to the ring trunk R.
All cut from BI-? 1", the called party is cut off from the calling signal trunk RG1 or I, creating a communication path connecting the two parties.

(8) When a communication path is established using the local trunk IOr,
The main control unit CPU monitors both ends of the rank 10T- to the local station 1 by the trunk scanning unit TSCN, and detects the end of the call (on-hook). When either party goes on-hook, the main control unit CPU disconnects both parties from the communication path and ends the call.

B: When a call is made or received from the local station, and the called subscriber has registered for the calling party ID service. The control sequence in this case is shown in FIG. 2B.

The sequence of (1) to (4) is the same as the sequence of (1) to (4) in case A described above.

(5) When it is detected through incoming call analysis that the called subscriber has registered for the calling party ID service, the local trunk IO'r' and the incoming calling party ID notification trunk RS T
, Ringing signal 1-Rank R' G T , Ringing tone 1-Rank R [3T is checked for availability and put on hold.

(6) If the number is empty, the calling subscriber's line is given a ringing tone 1 - rank r<
Connect P)'r and send a ring tone to the calling phone (Iku) to notify the other party that you are calling.At the same time, call +J1
．． Connect the incoming caller ID notification trunk R3T to the single-person line, and read the optical call tone number transferred from the sequence r: OII T- memory area to the R3l memory area in (5) above. , RST via OM signal or OF
It is transmitted in the same manner as the relay verse selection signal transmission in low signal format tones. Thereafter, it waits for a certain period of time for information from the called subscriber to accept or reject the incoming call W1.

As will be described later, the sequence (6) above is sent to subscriber telephones that have registered for the calling party ID service in the form of an OM signal or an OF low signal. It has an added function of receiving information and displaying the number on a display or printing it out with a printer.

The called party can confirm who is calling by displaying or printing the caller's number before the ringtone, and if he or she accepts the call, he or she can leave it alone. If you do not want to receive the call (in the case of rejecting the call), you will take the telephone off-hook within a certain period of time after receiving the calling number.This is a response indicating your intention to reject the call.

(61) If the called subscriber goes off-hook within a certain period of time after receiving the calling party number and responds with an intention to reject the call, the main controller CPU immediately disconnects the called subscriber line. In addition, one calling subscriber line has a ring trunk RB.
By connecting the busy tone trunk BBT instead of T and changing the ring tone to the busy tone, the caller is informed that the incoming IE has been rejected. This sequence ends when the caller asks for busy tone and goes on-hook, and all communications are complete.

(62) If the called subscriber does not go off-hook within a certain period of time even after receiving the calling party number, the main controller CP t
It is determined that J intends to receive the call, and the call is placed on the called subscriber's line? :1
1g Calling signal trunk RG is connected instead of calling party ID trunk RST. In other words, 1 (sends a ringing signal to the called telephone via G1 and rings the bell;
Report an incoming call. After this, the called subscriber's response is sent to the trunk scanning device 'r' S via the ringing signal 1 to rank RG1.
Monitor with CN.

The sequence of (7) and (8) is (7) of A in the previous case.
This is the same as the sequence (8).

In the case of calls made and received by C...Central phase; The control sequence in this case is shown in FIG. 2C.

The sequence of <1) to (4) is (1) to (1) of Δ in the previous case)
This is the same as the sequence (4).

(51) If it is detected in the i-communication analysis that the called subscriber is another station, check the availability of the outgoing sender trunk OS T' and the outgoing trunk OGI, and if there is space, the outgoing sender 1-rank 08Th The called subscriber number is transferred to the destination exchange as a selection signal for the OM other signal or OF low signal via the Hinode trunk OG 1'.

(5,2)! In the exchange, the called subscription & number is received as a selection signal at the incoming register 1-rank IRT via the incoming trunk ICT. When the input register 1 rank IRT receives the selection signal, it stores it in the reception number area in the IR-1 memory area.

(53) When the reception of the selection signal by the input register IR is completed, the main control unit CPU analyzes the incoming call based on the call subscriber number in the IRT message memory area.

As a result of incoming call analysis, if the called subscriber has not registered for the calling party N notification service, the ring tone trunk RBT,
Check whether the ringing signal trunk RG T is vacant and execute the same sequence as in (6) and subsequent steps in the previous case.

(54) As a result of the incoming call analysis, if the called subscriber has not registered for the calling party ID service, sends a calling party ID notification request to the originating exchange and transmits the called subscriber number as a selection signal. The calling party number is transferred to the receiving exchange in the same way as the caller.

(55) When the reception of the calling party's number is completed at the receiving exchange, is there an incoming calling party's ID notification trunk? < s 1-.

Ringing signal trunk RGT: Check whether the ringing trunk R137 is empty, and then execute the sequence from (6) onwards in case B.

The above is an example of the control sheets of the switching system with the calling party number notification function, which is the premise of the present invention. next,
The structure of the telephone according to this invention will now be disclosed.

The transmitting/receiving network 32 is a well-known telephone circuit such as a 600 type or 601 type, and includes a handset 33 and a bell 3.
It has 4. The transmitting/receiving circuit network 32 including the handset/receiver 33J5 and the bell 34 has the structure of a normal telephone set. In addition to the above configuration, the telephone of the present invention includes a calling number receiving circuit 35, a microcomputer 36, a memory 37, a display 38, and a power supply circuit 39 for operating these.

The input end of the calling party number receiving circuit 35 is connected to the hook switch 4.
It is connected to the subscriber line 30 via a coupling capacitor 1)7!11. The hook switch 40 is a contact that is linked to seven switches in the transmitting/receiving circuit network 32, and is a contact that is closed when the handset 33 is on-hook. That is, while the handset 33 is on-hook, the subscriber 130 is also connected to the calling party number receiving circuit 35 via the coupling capacitor 41. In this state, as explained earlier, when the calling party number is sent from the switching equipment in the form of an OM double signal or an OF signal prior to the paging signal, that signal is sent to the calling party number receiving circuit 3.
5 and demodulated.

When you cover the handset 33 with the hook switch 40
is opened, and the calling number receiving circuit 35 is disconnected from the subscriber 130 side.

Microcomputer 36 executes a program stored in memory 37 and controls calling party number receiving circuit 35 and display 38. When the calling party number is received by the calling party number receiving circuit 35, the number information is transmitted to the microcomputer 36, and the number is displayed on the display 38 under the control of the microcomputer 36. The display of the calling party number continues until the handset 33 is once off-hook and then on-hook again.

As the display device 38, in addition to a liquid crystal panel FLED panel or a fluorescent display device, a printer for printing an optical caller number may be used. When a printer is used as the display 38, an additional effect can be obtained in that the numbers of calls made while the user is away are automatically recorded and retained. Therefore, both a display device using a liquid crystal panel and the like and a printer may be provided.
