However, in the conventional automatic telephone number information creation device, for example, when calling a fixed and mobile phone number distributed throughout the country, about 9,999,999 calculated from the number of digits following the telephone number prefix “0”. Nineteen logical value numbers are narrowed down to the out-of-city and local area codes permitted by the Ministry of Internal Affairs and Communications, a list of about 390 million phone numbers is generated, and the computer reads ISDN while reading this phone number list. When a call is made to the network, the called terminal is connected to a transfer telephone or MNP.
(Multi-number portability) phone numbers are included, so there is a problem that even if the ISDN line is disconnected immediately after acquiring the reason display number, it will be charged with the establishment of about 0.005% to 0.29% of the total Was. For example, since a monthly charge of about 4 million yen is generated, there is a problem that it is difficult to reduce the monthly operating cost of the telephone number information automatic creation device. In addition, the recent progress in telecommunications technology has shifted from analog network to digital network, and from now on FTTH (
A plan to construct an IP telephone network using optical fiber) has been promoted, and a public network using FTTH (optical fiber) has spread throughout the country from the copper wire (dry copper) used by conventional analog telephones. , IP telephones (for example, a telephone carrier starting with the prefix “050” is allocated to a carrier having the highest number of IP telephone numbers designated as 5.78 million) is expected to increase.

Then, when a call is made from the ISDN line network to the IP phone using the conventional method and the telephone number usage status survey is conducted, it is almost 100% charged, and all IP phone numbers are recorded via the ISDN network. There is a problem that enormous research costs are incurred when calling and investigating. It is an object of the present invention to provide an apparatus for automatically generating telephone number information that is not charged and is not connected to a communication terminal having a telephone number that is called in a telephone number usage status survey. Accordingly, since the telephone number information automatic generation apparatus is not connected to the telephone side communication terminal and the telephone line, the communication terminal is not ringed, so that the incoming side user is not disturbed. In addition, conventional IS
Provided a new automatic telephone number information generation device to replace the automatic telephone number information generation device using the DN line technology. From the first generation telephone number information acquisition technology using analog line signals, the IS
It is also possible to shift to the second generation telephone number information acquisition technology using the DN line signal, and to correspond to the third generation telephone number information acquisition technique using the IP telephone line signal in the near future. It is a problem.

The present invention has been made in response to such problems, and calls a telephone number from a computer to the SIP server using the SIP protocol installed in a telephone company or Internet service provider via the Internet. The IP telephone adapter sends a message containing the telephone number to the SIP server, the SIP server determines the IP address of the called party, and communicates between the calling computer and the communication device including the called telephone. Establish.

And if the phone number you are calling is a “valid” phone number that has been paid out from the telecommunications business, or a “invalid” phone number that has not been paid out from the telecommunications business, Automatic telephone number information that allows the computer to analyze the status code of the SIP server, which is a response message, and record it electronically to a storage medium, whether it is a telephone number, a telephone number in a relocated state or a temporary relocated state that cannot make a call An object of the present invention is to provide a creation device and a method thereof.

Here, the SIP server is a server that uses a protocol called SIP (Session Initiation Protocol) to associate a telephone number with an IP address and perform call control for calling a partner telephone number and connecting a telephone line. . Conventional IP phone service and NGN (Next Generation Network)
). Especially in NGN, it has a function to instruct bandwidth control, which is its greatest feature, and to provide accounting and authentication information to an external server connected to the Internet.
It plays a central role in the NGN server group. There are two types of SIP servers: software types installed on general-purpose servers and types that provide hardware equipped with SIP server software. Hardware-mounted SIP servers have high reliability and high-speed processing capability for NGN. .

NGN is a next-generation network constructed based on the Internet protocol IP. Currently, a telephone network and an IP network for Internet services are maintained separately. The next-generation network aims to provide an IP-based network on which various services such as broadcasting, authentication services, location information services, and multimedia conferencing are provided in addition to telephone and Internet connections. A ubiquitous network society can be realized by constructing an IP-based network with improved QoS and security and deploying various services. The first step is to replace the telephone network with the IP network in each country.
In Japan, KDDI has completed IP conversion by 2008, and the NTT Group plans to use IP by the first half of 2010. Currently, NGN standardization is being promoted mainly by ITU-T. In Japan, the Ministry of Internal Affairs and Communications established the “IP Network Equipment Committee” in November 2005.
The Network Promotion Forum was established in December 2005.

In order to achieve the above object, the automatic telephone number information creation apparatus according to the present invention, for example, as shown in FIG. 1, is a number that has a telephone number in advance, starting with a prefix “0” that specifies a domestic telephone number. A storage device 12 for storing a number table, and a number table is read from the storage device 12, and transmission / reception information when a telephone number is called via the IP network 18 using the auto dial transmission means 16 is collected and stored in the storage device 12 A communication log storage means (Asterisk1.4) stored in the communication log storage means, and a communication disconnection means for disconnecting the communication line that is calling when the communication log storage means obtains a status code indicating whether or not a call is possible from the SIP server 30. Prepare.

With this configuration, the telephone number calling from the transmission / reception information of the IP network 18 is a valid telephone number paid out from the telecommunications carrier, or invalid that is not paid out from the telecommunications carrier. It is possible to determine whether it is a phone number, a phone number on hold, a phone number that has been transferred or temporarily transferred, and before it rings the incoming caller's phone terminal, so every month or once every other month or quarter The telephone number history is stored in a storage device by calling at a predetermined interval of
A history of telephone number information can be accumulated. In this embodiment, transmission and reception PCs are provided separately. However, the present invention is not limited to these two PCs, and may be implemented using, for example, a single workstation using a dual processor. You can also.

As described above, whether the telephone number to be called is “valid” issued from the telecommunications carrier or “invalid” not issued from the telecommunications carrier is determined as to whether or not the IP telephone network Thus, it is possible to automatically identify the response signal (SIP response code) and record it in an electronic storage medium, so that the telephone number history can be checked accurately and while avoiding unnecessary charges.

An embodiment of the present invention will be described with reference to FIGS. The telephone number information automatic generation apparatus 10 according to the present embodiment is generally configured to access an IP network using a personal computer or a workstation and perform telephone communication such as a general fixed telephone, a mobile phone terminal, and an IP telephone terminal. Since the SIP response code returned from the SIP server 30 is sequentially stored as the telephone number information of the device, and the telephone line can be disconnected by detecting the status code indicating whether or not a predetermined call is possible, the validity or invalidity of the telephone number And the hold status, transfer status, or temporary transfer status can be instantly grasped, and the line to the IP telephone network can be disconnected before the called communication terminal rings. It is possible to prevent ringing and to significantly reduce the billing rate for calling a telephone number.

FIG. 1 is a system configuration diagram schematically showing the overall configuration of an automatic telephone number information creation apparatus according to an embodiment of the present invention. As shown in the figure, the telephone number information automatic creation device 10 is a PC software for execution by a PCone 10a for outgoing calls, a PCtwo 10b for recording communication logs, a storage device 12 to which a hard disk or flash memory can be applied, and a CPU (not shown). The communication log storage means 20 (Asterisk1.4) is provided, and the Pcon 10a has an IP address “
192.168.0.3 "is assigned, and the PCtwo 10b has an IP address" 192.168. "
68.0.6 "are assigned to each other, and both of the automatic dial transmission means 16 via the LAN cable.
Connected to.

The auto-dial transmission means 16 is connected to the IP telephone adapter 14 and is connected to the IP telephone terminal 22 connected to the IP telephone network 18 or the fixed telephone 26 connected to the public line network 24 or the mobile telephone connected to the mobile telephone network. Collect transmission / reception information when a call is made to the terminal 28, and PCt
The computer 10 (Asterisk 1.4), which is the communication log storage means 20, can execute the wo 10 b and store the communication log in the storage device 12. Such a member or circuit can be controlled by a central processing unit CPU or a digital signal processor (not shown). Both the outgoing PCone 10a and the communication log recording PCtwo 10b are connected to the IP network through a router instead of the IP telephone adapter 14. It can also be connected.

The telephone number information automatic creation device 10 starts up the computer software “X-Lite 3.0” using the PCone 10a, and the IP telephone terminal via the SIP server 30 from the auto dial transmission device 16 and the IP phone adapter 14 22, General landline telephone 26
When the mobile phone terminal 28 is called and connected to the called terminal, the communication line is automatically disconnected in the initial process of the telephone call. In other words, the telephone number information automatic creation device 10 terminates the SIP protocol, releases the calling state, and disconnects the communication line when it detects a SIP response code indicating whether communication is possible, which is returned from the SIP server 30.

Therefore, when the telephone number information automatic creation device 10 cannot connect to the called terminal via the SIP server 30, it acquires error information returned from the IP network 18 and disconnects the communication line.

The telephone number information automatic generation apparatus 10 can transmit / receive information to / from the IP network 18 (for example, a request or a response corresponds) even when it can or cannot be connected to the terminal on the called side.
Is automatically stored in the storage device 12 as a log file by the communication log storage means 20 (Asterisk 1.4). By using the headphone microphone 32, the operator can transmit and receive a transmission / reception signal as an audio signal.

The core configuration requirement of the present embodiment is to include a communication disconnecting unit that forcibly disconnects the communication line after acquiring the SIP server information (SIP response code).

Specifically, the telephone number information automatic creation device 10 uses the Internet IP network and performs SI
By analyzing the status code stipulated in RFC 3261 in the P protocol and returned from the SIP server 30, whether the calling telephone number actually exists, whether it has been transferred, or the transfer destination new telephone number is acquired. The telephone network is not connected to the call side communication terminal, is not charged, and the usage status of the target telephone number is indicated without ringing the call side communication terminal.
Can be investigated via.

Here, there are currently 62 types of RFC 3261 status code lists, which are added sequentially. This SIP protocol specified value is disclosed in the SIP detailed text (issuing office: Rick Telecom Co., Ltd.).

By implementing the telephone number information automatic generation apparatus 10 of this embodiment, it is possible to provide an epoch-making means capable of investigating the usage status of telephone numbers from Japan to overseas countries without incurring extra costs.
Of course, it is a matter of course that the telephone number information automatic creation device 10 may be installed in the country of the country to be investigated. Therefore, since the prior art is based on the premise that a public line (ISDN) is used, in order to prevent congestion of the international line network, a large number of leased line contracts are presupposed and enormous costs are required. Therefore, the telephone number search is practically impossible from the viewpoint of cost by the conventional means.

For example, in countries such as China where an exchange network is not yet established, mobile phones and IP phones are naturally popular. Metropolitan areas are central to wired landline telephones. In rural areas such as China, communication networks that use radio waves are often adopted due to the cost of wired facilities such as vast territory and problems of very long distances. Therefore, IP telephones and mobile phones that have a low communication network maintenance cost are widespread.

According to the automatic telephone number information creation apparatus 10 of the present embodiment, the valid and invalid telephone number tables are stored in the storage device 12 by the automatic telephone number creation process routine. If an invalid telephone number table is obtained, update information of telephone numbers that are newly established or unused every time can be obtained. In particular, the updated data of new telephone numbers that have not been paid out in the past by telecommunications carriers will be useful information to at least eliminate information leakage, and the telephone numbers that were valid in the past will be based on the latest survey data. Needless to say, even if the transaction is invalidated, it becomes valid information in the credit examination. Further, by acquiring the response message code from the IP telephone adapter 14 on the calling side and storing it in the storage device 12, in addition to determining whether the telephone number is valid or invalid, the hold state, the transfer state, or the temporary transfer state Can be identified. The following Table 19 to Table 26 show the SIP server 3
Indicates a status code of 0.

The above status code is received via the IP telephone adapter 14, and this status code is stored in the storage device 12. Therefore, according to the automatic telephone number information creation device 10 of the present embodiment, an effective telephone number group that exists actually Are at least “180”, “200”, “202”

Any one status code among “603”, “604”, and “606” is included.

Tables 27, 28, and 29 show a list of valid and invalid telephone numbers.
“O” in the determination target column shown in the table indicates a status code that can be determined valid or invalid in the status codes returned from the SIP server, and indicates a provisional response corresponding to each status code, a request being received or being processed. The response code shown is described. Further, “00” in the determination result column shown in the table indicates a state in which a valid telephone number exists, and “01” in the same column.
Indicates the status of the invalid telephone number that has been removed, and “99” in the same column indicates an invalid telephone number indicating whether it is unknown whether it has been paid out by the communication carrier.

The automatic telephone number information creation apparatus 10 of the present embodiment uses an area code (for example, “0” for an IP telephone).
50 "prefix, fixed and mobile phone prefix when NGN is in place),
Realize in the country by identifying the switching office or SIP server from the local station number (XXXX) and using the phone number array characteristics based on the identified station number (requiring a logical number from 4 digits 0000 to 9999 for the subscriber number) The status code information returned from the SIP server 30 is sequentially detected and stored in the hard disk as the storage device 12 for the validity (for example, the currently in-use number) of the IP phone.
At the same time, the invalidity of the telephone number is detected from the status code information returned from the SIP server 30 and stored in the hard disk as the storage device 12.

In the telephone number information automatic creation device 10, the survey date and time when the telephone number is called can also be stored in the storage device 12. At least a telephone number group used as an IP telephone is created from the area code, local area code, and subscriber number (0000 to 9999), and a valid telephone number and an invalid telephone number are selected from the telephone number group. Classification and table information can be created in the storage device 12.

In addition, if the status code information is analyzed in detail, it is also possible to newly classify and store in the storage device 12 telephone numbers that are instructed to be relocated and new telephone numbers that are being guided out of invalid telephone numbers. .

In addition, based on the invalid phone number group, the ISDN network is used to collect the reason display information that is sent back from the exchange along with the disconnect message, and the transfer guide phone number (including the new phone number) and the convenience based on the reason display are collected. The removal telephone number, (temporary removal telephone number), etc. are collected and the telephone number transmission device can be used to confirm the accuracy of the telephone number survey result, and to find and correct deficiencies. For example, the telephone number information automatic generation apparatus 10 of this embodiment may be provided with a transmission means to the public line network and a transmission means to the Internet network. However, since calling the public line network to a valid phone number is not desirable in terms of cost effectiveness because charging is currently incurred, for example, only an invalid phone number collected by the telephone number information automatic creation device 10 is used. It is possible to prevent the billing of the call charge and the ringing communication terminal from ringing again by automatically dialing.

Further, in the present embodiment, an IP address that can be detected accompanying the IP telephone number can be acquired at the same time. In this IP phone, the location where the communication terminal is installed and the area where it is used are not known, such as the area code or the city code provided by NTT.

Therefore, the IP address of the called communication terminal is acquired from the SIP server, and the area transmitted (returned) from the called communication terminal is determined from this IP address. Knowing the IP phone's calling area means matching the address of the person calling from the IP address using the IP address, the time when the person was ordered, the time when the same person was next ordered, etc. It can be used for fraud prevention such as impersonation by performing sex check.

In this case, it goes without saying that in addition to the telephone number information history check, the position information of the communication terminal can be used for credit examination. For example, if the address is in Sagamihara City, Kanagawa, and the area where the IP address is used is in Shizuoka Prefecture, we will handle impersonation and fraud by carefully processing orders (billing resident cards, cash on delivery, field surveys, etc.) Can be prevented.

FIG. 13 is a block diagram of the automatic telephone number information creation apparatus 1 used for reinvestigating invalid telephone numbers. The telephone number information automatic creation apparatus 1 reads an invalid telephone number from a storage device 12 (see FIG. 1), stores an invalid telephone number database 2 that stores a number table of invalid telephone numbers, and a display that displays a survey result. 3, a keyboard 4 for inputting an instruction for reinvestigating invalid telephone numbers, a pointing device 5 for selecting and operating an icon displayed on the display 3, and calling an invalid telephone number to an ISDN line by an automatic dial transmission means. CP (not shown) that collects a disconnect message and reason display information returned from the call exchange 9
A telephone number cleaning program 6 executed by U is installed.

The calling side exchange 9 responds to the call processing of the telephone number information automatic generation device 1 and starts telephone communication with the exchange specified by the area code and the local number. For example, the calling side exchange 9 is connected to any one of the public line exchange 8a, the mobile phone exchange 8b, the PHS exchange 8c, and the IP telephone exchange (not shown), and the fixed telephone 9a designated for each exchange. Mobile phone 9b
Then, telephone communication is started between the PHS terminal 9c and the IP telephone (not shown). Then, the calling side exchange 9 returns the telephone number information to the automatic creation apparatus 1 while receiving the ISDN connection signal from the calling exchange.

The telephone number information automatic generation device 1 can automatically collect the usage status of the telephone number being called from the calling side exchange 9, and the telephone number information is automatically generated by the telephone number information automatic generation device 10. Since the number is determined to be invalid, there is a very low probability of charging for ISDN calls and ringing the called terminal device. Moreover, it is possible to determine the transfer telephone number, the temporarily removed telephone number, and the office deposit telephone number with a high probability from the reason display information by a voice message.

FIG. 14 is a diagram showing an operation sequence of the automatic telephone number information creation apparatus 1. The telephone number information automatic creating apparatus 1 executes a call setting message transmission process in step 28 (hereinafter, step is abbreviated as “S”). For example, the transmission capability of ISDN is designated as “voice” and transmitted.

The telephone number information automatic creation device 1 determines the connection signal received from the calling side exchange 9 by any one of the processes S29 to S31, determines that it is a valid telephone number in the progress display message reception S29, and branches to S36. The telephone number information automatic creation device 1 sends a disconnect message to the ISDN network, and in S37, the telephone number check result is issued as a transfer telephone identification process to generate a number representing the actual "01" or the transfer "11". Corresponding to the called telephone number, it is stored in the invalid telephone number database 2.

Further, the telephone number information automatic creation device 1 determines the connection signal information branched to the response message reception S30 or the call message reception S31, and if it matches (YES) each signal, I
The SDN line is disconnected, and the actual number “01” is stored in the invalid telephone number database 2 in association with the telephone number that made the call as a result of the investigation. For example, it is effective when the phone number changes from a missing number to a valid phone number very rarely.

If the telephone number information automatic creation device 1 does not match (NO) in the determination process of S29 to S31, the process proceeds to disconnection message reception S32, and if the disconnection message cannot be detected, the process returns to S29 to activate the valid phone. The number determination process is repeated over a predetermined period. On the other hand, if it is determined that the disconnect message has been received, the process is branched to S33, and the ISDN line disconnection process is executed.

The telephone number information automatic creating apparatus 1 executes the “reason display” information element acquisition process S34 attached to the disconnection message, and then shifts the process to S35 to execute the reason display value distribution process.

In the reason display value distribution process S35, the telephone number that is called in correspondence with the reason display is transferred “02”, convenience removal “03”, number error “04”, classification unsupported “05”, and invalid number “06”. ”, Removal“ 07 ”, insufficient acquisition number“ 08 ”, missing number“ 09 ”, line error“ 50 ”
”Is stored in the invalid telephone number database 2 in association with the telephone number that made the call.

As described above, according to the telephone number information automatic creation device 10 of the present embodiment, the valid and invalid phone number tables can be stored and stored in the storage device 12 from the existing phone numbers, so that they are temporarily invalidated.
