Abstract

PROBLEM TO BE SOLVED: To provide an erroneous dialing detecting system for detecting erroneous dialing of a received telephone number and informing a calling person of erroneous dialing. SOLUTION: A database 40 responds to the registering inquiry of the received telephone number from a telephone number retrieval control part 62. A data retrieving part 42 retrieves a data storage part 41 and detects the presence/ absence of registering of numerical data to judge whether a call is normal or abnormal. In the case of the abnormal call, when detecting the excessive or short digits, the erroneous number of an optional digit or the alternation of adjacent number of an optional digit, the database 40 selects numerical data which is the nearest to inquired numerical data from the data storing data and informs the telephone number retrieval control part of it. The telephone number retrieval control part inquires of the calling person whether the call is originated with a received telephone number or a similar telephone number by a telephone number message and carries out call processing in accordance with response information from the calling person.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an erroneous dial detection system and, more particularly, to a system in which an exchange detects an error in a telephone number of a destination received from a caller and notifies the caller of the error.

[0002]

2. Description of the Related Art When an exchange unconditionally forms a connection channel for a called party based on a subscriber number of a called party received from the calling party, if the calling party makes a dial error, the called party answers and starts talking. At that point, it turns out that the call was wrong.

[0003] In order to prevent such a wrong telephone call,
A database storing the eight-digit and ten-digit telephone numbers existing in the telephone network, and all the station numbers (1 to
4) and an 10-digit table in which all 10-digit telephone numbers (1 to 4) are registered,
When the switch receives the destination phone number from the caller,
The number of digits of the received destination telephone number is identified, the 8-digit table or the 10-digit table is searched, and the presence / absence of a station number registration that matches the upper digit (station number) of the identified destination telephone number is determined. If the station number is registered, it is determined that the call is normal and the call arrives at the destination telephone.If the corresponding station number is not registered, it is determined that the call is abnormal, and the talkie device announces an incorrect dialing to the caller. Is disclosed in, for example, JP-A-07-297917.

[0004]

SUMMARY OF THE INVENTION The above-mentioned JP-A-07-29 is disclosed.

Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a relay system diagram of the erroneous dial detection system of the present invention, and FIG.

As shown in FIG. 1, the erroneous dial detection system of the present invention, as shown in FIG. 1, a caller 10, recipients 20 and 30, a database 40 for erroneous dial detection, and a voice response for sending various messages to the caller. The device 50 and the exchange 6
0.

The database 40 is a data storage unit 41 for storing numerical data of the telephone number of the destination to which the subscriber of the erroneous dial notification service requests registration in advance or as required.
Call state determining means for retrieving whether or not the telephone number from the caller received from the exchange 60 is registered in the data storage unit 41 to determine whether the call is normal or abnormal; And a data search unit 42 provided with an ambiguity detecting means for detecting an abnormal cause and detecting an approximate telephone number closest to the received telephone number when the determination is made.

The exchange 60 receives the telephone number information dialed by the caller and converts it into numeric data. The dial information receiving unit 61 transfers the numeric data of the telephone number information received by the dial information receiving unit 61 to the database 40. Requesting a search for a telephone number, and transmitting a telephone number confirmation message, a received telephone number non-registration notification message, a telephone number notification message to the caller based on the search result from the database 40, and a caller's response to the above various messages. A telephone number search control unit 62 and a telephone number search control unit 6 that control the identification of the response information, the selection of the telephone number of the destination corresponding to the identified response information, the registration and deletion of the telephone number, and the like.
2 includes a message control unit 63 for instructing the voice response apparatus 50 to transmit a corresponding message in response to the request of No. 2, and a call control unit 64 for transmitting a call to the destination selected by the telephone number search control unit 62. .

Next, an erroneous dial detection process will be described with reference to FIG. 2 and FIG. The telephone number information dialed by the caller 10 who is a subscriber of the erroneous dial notification service is sent to the dial information receiving unit 61 of the exchange 60 via the telephone line.
Is received (step S101 in FIG. 2).

The dial information receiving unit 61 analyzes the received telephone number information, converts it into numeric data, and transfers it to the telephone number search control unit 62. The telephone number search control unit 62 stores the numeric data corresponding to the telephone number (received telephone number) of the called party transferred from the dial information receiving unit 61 in the database 40.
And a search is made to determine whether or not numeric data corresponding to the received telephone number is registered (S102).

The data search unit 42 of the database 40
The data storage unit 41 is accessed based on the numeric data transferred from the telephone number search control unit 62, and the numeric data requested by the telephone number search control unit 62 is searched.

This search processing is performed as follows. First, it is searched whether or not the same numeric data as the numeric data transferred from the telephone number search control unit 62 is registered (S103). If the same numeric data is registered, it is determined that the call is normal. Then, it reports to the telephone number search control unit 62.

If the same numeric data is not registered, it is determined that the call is abnormal and the fuzzy search means determines whether the numeric data transferred from the telephone number search control unit 62 has an insufficient number of digits, an excessive number of digits, or an arbitrary number. Is determined, the number of the adjacent digit is replaced, and the like is reported to the telephone number search control unit 62.

That is, it is determined whether or not the digit data transmitted from the telephone number search control unit 62 has an insufficient number of digits by the digit insufficient detection means (S104). If the digit data is insufficient, the process proceeds to step S109. If the result of the determination in step S104 is not that the number of digits is not insufficient, it is determined by the digit excess detection means whether or not the number of digits is excessive (S105). If the number of digits is excessive, the process proceeds to step S109.

If the result of the determination in step S105 is that the number of digits is not exceeded, it is determined by the digit number difference detecting means whether there is a difference in numeric data of an arbitrary digit (S106). The process moves to S109.

If the result of the determination in step S106 is not a difference between the numeric data of an arbitrary digit, it is determined by the adjacent number replacement detecting means whether or not the numeric data of an arbitrary digit is replaced (S107). In the case of replacement, the process proceeds to step S109.

If the result of determination in step S107 is not replacement of adjacent numeric data, it is determined that the numeric data corresponds to a new telephone number, and the search data is transferred to the telephone number search control unit 62.

The telephone number search control unit 62 is a database 4
When numeric data which is a new telephone number from 0 is received, the message control unit 63 is instructed to transmit a received telephone number non-registered notification message including the information on the unregistered received telephone number and the inquiry about the calling process. 63 controls the voice response device 50 to transmit a received telephone number non-registration notification message to the caller 10 (S108).

This telephone number non-registration notification message may be, for example, "The telephone number you have called is not registered. If you want to make a call without registering, send 0; If you want to register without doing so, please press 2. "and ask the caller's intention.

The data search unit 42 of the database 40
When the result of the determination in step S104 is that the number of digits is insufficient,
If the result of the determination in step S105 is that the number of digits has been exceeded,
When the result of the determination in step S106 is a difference in numeric data of an arbitrary digit, and when the result of determination in step S107 is replacement of adjacent numeric data in an arbitrary digit, the telephone number of the called party registered in the data storage unit 42 The numerical data closest to the telephone number information received from the caller 10 is searched from among the numerical data, and transferred to the telephone number search control unit 62.

The telephone number search control unit 62 is a database 4
When the approximate numeric data is received from 0, the numeric data corresponding to the telephone number information received from the caller 10 and the approximate numeric data received from the database 40 are transferred to the message control unit 63 to request transmission of a telephone number notification message. .

The message control unit 63 receives the request from the telephone number search control unit 62, and instructs the voice response unit 50 to transmit the numerical data corresponding to the telephone number information received from the caller 10, the approximate numerical data received from the database 40, and the transmission thereof. It requests the generation of a telephone number notification message including the processing inquiry information, and transmits the telephone number notification message generated by the voice response device 50 to the caller 10 (S108).

The telephone number notification message may be, for example, “The dialed telephone number 123-4567 is unregistered, but 0 is sent if the call is made without registration, 1 is sent if the call is registered and sent. If you do not want to register, press 2. Also, call the phone number 123-4
Press 3 to call the closest phone number to 567, 123-5567. To hear the caller's intention.

When response information from the caller to the telephone number non-registration notification message in step S108 is received (S111), it is determined whether or not the response information is a call request using the received telephone number (S112).

If the result of the determination in step S112 is a call request using the received telephone number, it is determined whether there is a request for registration of the received telephone number (S116). If there is a registration request, the received telephone number is registered in the database 40. After that (S117), the process proceeds to the transmission process (S118).

If the result of the determination in step S116 is that there is no registration request, the process proceeds to the transmission process (S118) without registering the received telephone number in the database 40.

If the result of the determination in step S112 is not a call request using the received telephone number, it is determined whether or not a request for registration of the received telephone number is made without making a call (S114). Is completed, and if there is a registration request, the received telephone number is registered in the database 40 (S115), and the erroneous dial detection process ends.

When response information from the caller to the telephone number notification message in step S110 is received (S111), it is determined whether or not the response information is a call request using the receiving telephone number (S112). In the case of an outgoing call request with a number, it is determined whether or not there is a request for registration of the receiving telephone number (S116). If there is a registration request, the receiving telephone number is registered in the database 40 (S11).
7) The process proceeds to the transmission process (S118).

If the result of the determination in step S112 is not a transmission request using the received telephone number, it is determined whether the request is a transmission request using an approximate telephone number (S113). ).

If the result of the determination in step S113 is not a call request using an approximate telephone number, it is determined whether or not a request for registration of an approximate telephone number is made without making a call (S114). When the registration has been completed and there is a registration request, the approximate reception number is registered in the database 40 (S115), and the erroneous dial detection process ends.

When the result of the determination in step S103 is a normal call, a telephone number confirmation message for confirming the received telephone number of the called party is transmitted to the sender 10 (S122).

When response information from the caller 10 to the telephone number confirmation message in step S122 is received (S123), it is determined whether or not the response information is a call request using the received telephone number (S124). In the case of an outgoing call request, the process proceeds to an outgoing call process (step S118).

If the result of the determination in step S124 is not a transmission request using the received telephone number, it is determined whether or not there is a deregistration request for the received telephone number (S125). If there is no deregistration request, the erroneous dial detection process ends. If there is a registration deletion request, the received telephone number registered in the database 40 is deleted (S126), and the erroneous dial detection process is terminated.

If the result of the determination in step S113 is that there is a call request using an approximate telephone number, the call control unit 64 makes a call using the approximate telephone number and connects to the called party 20 (S1).
18) Also, when the determination result in step S116 is that there is no registration request, when the determination result in step S116 is that there is a registration request, and the received telephone number is registered in the database 40 in step S117, and in step S12.
If the result of the determination in 4 indicates that there is a call request using the received telephone number, the call is transmitted using the received telephone number to connect with the called party 30 (S118), and the call is started (S119).

Thereafter, when the end of call is detected (S120),
The line is released (S121), and the transmission process ends.

[0046]

As described above, the erroneous dial detection system of the present invention compares a telephone number received from a caller with a plurality of telephone numbers registered in advance in a database to determine whether the call is normal or abnormal. In the case of an abnormal call, if the number of digits is insufficient, the number of digits is exceeded, the number of any digit is different, or the adjacent number of any digit is replaced by the ambiguous search means, the approximate phone number closest to the received phone number is detected. Then, the caller is requested by the telephone number notification message for the received telephone number, approximate telephone number, and the processing method, and the caller decides the processing method, so even if the caller makes a call without noticing the wrong dial, the exchange The phone number notification message sent from the side prior to the outgoing call process can recognize erroneous dialing, prevent erroneous calls, prevent inconvenience to the called party and avoid unnecessary trouble. That.

In particular, a mistaken telephone call at midnight or a large number of mistaken telephone calls in a company not only impairs the corporate image but also may result in damages compensation, and the effect is extremely high.

When a call is made to a destination not registered in the database, a telephone number notification message or
The received telephone number unregistered message informs the telephone number of the caller, so the caller can recognize whether or not the number has been dialed incorrectly, and can also specify the registration of that telephone number. Can also.

Further, the transmitted telephone number is notified by the telephone number confirmation message, and the deletion of the telephone number can be designated, so that the telephone number registered in the database can be easily deleted.

By providing such an erroneous dial detection function on the exchange side, a plurality of terminals such as a representative telephone of a company or the like can share a database, which is more effective than registration by individual terminals.
