Abstract

The basic mechanism of an IP telephone is very different from traditional telephone technology (fixed telephone network technology). Therefore, the telephone number utilization status investigation system for fixed telephones developed and improved by the applicant cannot cope with the telephone number of 050 IP telephone service.
A computer includes an operator-specific determination table in which a busy number determination condition is described in association with an operator assigned number. The busy number determination condition specifies at least one ISDN response information among ISDN response information that may be obtained from the ISDN when a call is made with the telephone number to be investigated as a called number. A call is made with the investigation target telephone number as the called number, response information is detected, and the response information is compared with the busy number determination condition to determine whether the number is a busy number.

Description

  The present invention is intended for an 11-digit telephone number beginning with “050”, which has been assigned since October 2002, for IP telephones. The present invention relates to a method and an apparatus for automatically determining whether or not a busy number is available when a call is made and automatically recording it by processing of a computer connected to ISDN.

  As is well known, in industries that handle large amounts of customer personal information, including telephone numbers, such as banks, credit card companies, consumer finance, and mail order sales, it is necessary to examine the usage status of telephone numbers ( To see if it is a phone number that is or is not being used). Applicants have been working on the development and improvement of computer systems since 1993 to efficiently and automatically conduct this type of research. A typical technique is described in detail in Japanese Patent No. 3462196.

  The number of IP telephone users has been increasing rapidly in recent years. As is well known, the basic mechanism of an IP telephone is very different from traditional telephone technology (fixed telephone network technology). For this reason, the telephone number utilization status investigation system for fixed telephones that has been developed and improved by the applicant has not been able to handle IP telephone numbers beginning with “050” (called 050 IP telephone service). .

  Nearly 20 companies have 050 IP telephone service. According to a study based on the applicant's demonstration experiment, it has been found that the construction method of the IP telephone network of each operator is not the same. As a result of continuing research on observing and analyzing the behavior of each company's IP telephone network through ISDN, the inventors have created the present invention described in detail below.

  In the present invention, ISDN response information for an outgoing call is analyzed based on a determination condition set for each carrier based on the carrier number assigned to the middle four digits of the telephone number. Similarly, it became possible to investigate the usage situation.

It is the schematic of the computer system in an Example. It is a conceptual diagram of the determination table classified by company in an Example.

=== Computer system ===
FIG. 1 shows an outline of a computer system that implements a telephone number utilization status investigation method according to the present invention. Here, a general personal computer 1 is used as the ISDN terminal. The computer 1 includes a CPU 2, a memory 3, a hard disk device 4, a display device 5, a keyboard 6, an ISDN communication board 7, and the like. The computer 1 is connected to the ISDN via an ISDN communication board 7 and a line connection unit (DSU) 8.

=== 050 IP phone service ===
As is well known, almost 20 companies in Japan currently provide 050 IP telephone service. The 050 IP telephone service can communicate with an existing fixed telephone network / ISDN / mobile telephone network. Therefore, the computer 1 connected to the ISDN can call the corresponding 050 IP telephone terminal by sending a call setting message having the telephone number of the 050 IP telephone service subscriber as the called number.

=== Numbering system of 050 IP phone ===
The telephone number of the 050 IP phone service is 11 digits, starting with the upper 3 digits 050, the middle 4 digits are the carrier assigned number assigned to each operator, and the remaining 4 digits are the subscriber number. ing.

=== Businesses to be surveyed ===
In the embodiment described below, the telephone numbers of the following four operators that provide 050 IP telephone service are targeted for investigation.
(1) KDDI: business operator allocation numbers “3000” to “3251”
(2) NTT Coprara: Business operator allocation numbers “7500” to “7625”
(3) STNet: business operator allocation number “8800” to “8808”
(4) UCOM: business operator allocation numbers “8880” to “8886”

=== Basics for judging busy numbers ===
As is well known, when a call setup message (setting voice as a transmission capability) is sent from the computer 1 with the telephone number in the ISDN as a called number, the computer 1 receives a call message or a response message as a response from the ISDN. In this case, the connection sequence to the terminal having the telephone number is performed, which means that a call can be made with the terminal having the telephone number. That is, the telephone number is a busy number (effective number or real number). This is a matter common to fixed telephones, mobile phones, and 050 IP telephones, and of course does not change depending on the 050 IP telephone service provider.

=== Disconnect message ===
As is well known, when a call setup message (setting voice as a transmission capability) is sent from the computer 1 with the telephone number in the ISDN as a called number, the computer 1 receives a disconnect message as a response from the ISDN. There is. This means that the execution of the connection sequence of the phone number to the terminal has been refused or interrupted, but this does not immediately mean that the phone number is an unused number (such as a missing number). Absent.

=== Display reason of disconnect message ===
The disconnect message issued by the ISDN and received by the computer 1 includes a “reason display” described in a prescribed data format. The “reason display” includes “reason number” and “generation source”. The details are defined in TTC standard JT-Q931 “ISDN user / network interface layer 3 specification”.

=== Business-specific judgment table ===
The hard disk device 4 of the computer 1 stores an operator-specific determination table whose concept is shown in FIG. The carrier-specific determination table is based on the combination of “reason number” and “generation source” of the disconnect message “reason display” when the disconnect message is received as a response after sending the call setting message from the computer 1 to the ISDN. The determination conditions for classifying the 050 IP telephone number as the called number as a busy number or classifying it as a non-use number are described for each of the above four operators.

  In the determination table for each business operator in the embodiment shown in FIG. 2, in the case of KDDI with business operator allocation numbers “3000” to “3251”, “reason number = 0, generation source = 0” and “reason number = 17, When a disconnection message of “generation source = 4” is received, it is determined that the 050 IP telephone number of the called number is an in-use number, and when a disconnection message of “reason number = 3, generation source = 4” is received, It is described that it is judged.

  Further, in the table of FIG. 2, in the case of STNets of business numbers “8800” to “8808”, “reason number = 0, generation source = 0” and “reason number = 17, generation source = 4” and “reason number”. = 21, generation source = 4 ”and“ reason number = 41, generation source = 4 ”, it is determined that the 050 IP telephone number of the called number is a busy number, and disconnection of“ reason number = 1, generation source = 4 ” It is described that when a message is received, it is determined as a non-use number.

  In creating the judgment table for each provider, although it refers to TTC standard JT-Q931 “ISDN user / network interface layer 3 specification”, it is a demonstration experiment based on the fact that it cannot be judged uniformly by this specification. Is used to derive the judgment condition.

=== Investigation work 1 (Individual processing) ===
One method of actual investigation work is a method of manually inputting a 050 IP telephone number to be investigated with the keyboard 6. An operator inputs a 050 IP telephone number A (which is one of the four operators) and gives a survey command. The computer 1 sends a call setup message with the number as the called number to the ISDN. When the computer 1 receives the call message or the response message, the computer 1 determines that the telephone number A is a busy number, records it in association with the telephone number A, and displays it on the display device 5.

  When the computer 1 receives the disconnect message as a response to the call setting message transmission of the telephone number A, it extracts the “reason number” and “generation source” of the “reason display”. Further, the computer 1 extracts a determination condition corresponding to the business number of the telephone number A from the business-specific determination table. Then, by contrasting both, it is determined whether it is a “reason number” and “generation source” to be determined as a busy number, or a non-use number, “reason number” and “generation source”. The determination result is recorded in association with the telephone number A, and any one of “in-use number”, “non-use number” and “determination hold” is displayed on the display device 5. A method of accepting the telephone number to be investigated by communication and returning the investigation result by communication can also be adopted.

=== Investigation work 2 (Batch processing) ===
For example, a list of 050 IP telephone numbers (any one of the four operators) recorded in a USB memory or the like is read into the computer 1, and the telephone numbers in the list are processed in the above-described order in order. The determination results of “medium number”, “non-use number” and “determination hold” are added and recorded as a determination flag to each telephone number and displayed on the display device 5. The telephone number list can be sent to the computer 1 by communication, and a survey result list with a determination flag can be sent back from the computer 1.

=== Investigation part 3 (All number processing) ===
In computer 1, 10,000 kinds of lower four digits are combined with the upper 3 digits of 050 and the middle 4 digits of any one of KDDI operator assignment numbers “3000” to “3251”. 050 IP phone numbers are generated in advance or sequentially, these phone numbers are investigated by the same batch processing as above, and the judgment results of “in-use number”, “non-use number” and “determination pending” are determined for each phone number. It is additionally recorded as a flag and displayed on the display device 5 if necessary. Of course, the same processing is performed for the allocation numbers of other businesses. It is also possible to generate all 10,000 telephone numbers in advance for each operator, and then investigate after these numbers are shuffled in any order.

  In addition, although four business operators of 050 IP telephone service were taken as an example, this is for the purpose of avoiding the complexity of the explanation, and a judgment table for each business operator based on a demonstration experiment is provided for all of the business enterprises near 20 companies. The creation is easily conceived from the description of the above embodiments and can be easily carried out.
