JP5386050B1 - Computing that distributes SMS by repeatedly issuing SMS transmission requests to the SMS transmission agency system based on a distribution list received from a client - Google Patents

Abstract

The method of requesting SMS transmission after confirming that a customer's mobile phone number is valid cannot eliminate the possibility that the SMS will reach another person different from the customer.
An SMS distribution system communicates with a client computer, receives a client identifier X and a distribution list Y, and performs number search processing, history verification processing, message creation processing, and message output processing based on the received identifier. In the distribution list Y, a plurality of records are described in which the mobile phone number A that is the SMS destination, the number registration date B corresponding to the date on which the client received the number A, and the message number C are associated. . In the history verification process, the number search result for the mobile phone number A recorded in the history database is verified, and invalid in the number search history after the number registration date B associated with the mobile phone number A in the distribution list Y In the case where there are consecutive number search results for a predetermined period, the message creation process / message transmission process is not performed.

Description

  The present invention relates to computing for sending SMS (Short Message Service) addressed to, for example, a mobile phone number described in a customer list, and in particular, based on a distribution list received from a client computer, an SMS transmission agent service provider. The present invention relates to computing that distributes SMS by continuously sending SMS transmission requests to a system.

=== Marketing using SMS ===
According to the SMS widely used in general, as long as the other party's mobile phone number is known, the SMS message (simple mail) can be delivered from the own mobile phone to the other's mobile phone. Since the customer's mobile phone numbers are often listed in recent customer lists at various operating companies, as part of marketing, addressed to a large number of mobile phone numbers on the customer list from the company's computer. A need has arisen for sending SMS. In order to respond to this need, there are companies that provide SMS transmission service in cooperation with mobile phone carriers (carriers).

  A company computer requesting SMS transmission is connected to an SMS transmission agency service company system (SNS transmission agency system) via the Internet, and a mobile phone number as a destination and a carrier identifier for identifying a mobile phone carrier When an SMS transmission request message including a message corresponding to the mail text is sent from the client computer to the SMS transmission agent system, the SMS transmission agent system acts on the carrier system corresponding to the carrier identifier and is designated. The message is delivered by SMS to the numbered mobile phone. By repeating such a transmission request operation according to the customer list, it is possible to distribute the SMS of a predetermined message to a large number of customer's mobile phones.

  As described above, since the SMS transmission request messages can be continuously transmitted from the client computer to the SMS transmission agent system one after another, if the client computer devise this business processing system, It is possible to substantially automate the business process of creating the transmission request messages one after another based on a large number of mobile phone numbers described in the customer list and transmitting them to the SMS transmission proxy system.

=== Marketing using direct mail ===
Direct mail has been used for some time as a representative marketing method. When direct mail is mailed based on a customer list, it is common practice to exclude customers who have already moved and are not likely to receive mail items from the shipping target in advance so as not to incur unnecessary costs. Various inventions utilized for such purposes are described in detail in the following documents.

(1) Japanese Patent No. 2801969 “Telephone Number List Cleaning Device and Cleaning Method”
(2) Japanese Patent No. 3227398 “Telephone Number Investigation Method and Device and Telephone Number List Cleaning Method”
(3) Japanese Patent No. 3462196 “Telephone Number List Cleaning Method”
(4) Japanese Patent No. 3998284 “Automatic device for creating telephone number information”
(5) Japanese Patent No. 4420265 "Telemarketing device and its program"
(6) Japanese Patent No. 4790573 “Computer System for Estimating Credit Rating of Telephone Contractor Based on Telephone Number”

  These prior inventions created a number search history database system. The number survey history database records the number survey results when regularly surveying numbers with a predetermined number of digits that can be used as telephone numbers, and is systematized so that the number survey results from the latest survey are added sequentially. Has been. The number survey result is associated with a survey date, a number of the predetermined number of digits, and information for distinguishing whether the number is valid or invalid as a telephone number on the survey date. Prior to sending direct mail to the customer, the database is checked for the telephone number of the customer, and if the latest number survey result of the number is invalid, the direct mail is not sent to the customer. It's being used.

=== Notes on distributing SMS as marketing ===
In the business of delivering SMS based on the customer list, similar to the direct mail delivery business, the number search history database is used to send a meaningless SMS or send an SMS to an unintended partner. The occurrence of inconvenience can be reduced. Inventions related to this are described in the following documents.

(7) JP 2010-258838 A "Short Message Service Address Translation Device and Method"
(8) Japanese Patent Application Laid-Open No. 2013-102414 "Message transmission apparatus and method and program"
(9) Japanese Patent No. 5265800 “Computing for detecting that a mobile phone user changes a carrier using number portability”

  As is well known, if a telephone number assigned to a user is canceled, the carrier (carrier) that provides the telephone service can immediately change the telephone number to another contract. The telephone number is stored in a non-use state for a predetermined period, and is allocated to a new contractor after the predetermined period has elapsed.

  Therefore, in conducting the marketing as described above, it is only possible to confirm that the customer's mobile phone number is valid and then send an SMS transmission request, and the possibility that the SMS will reach another person who is different from the customer. It cannot be excluded.

  In the invention described in the above (8) Japanese Patent Application Laid-Open No. 2013-102414, in paragraph No. 0003 of the publication, after clearly indicating that the above-mentioned problem may occur, The solution to the problem of “preventing a method to prevent it” has been described. In addition, paragraph number 0042 of the gazette describes in detail how records are recorded in the number search history database when a subscriber with the same telephone number is changed, and addressed to such a telephone number. It has been analyzed that there are cases where there is no problem even if SMS is transmitted and there are cases where erroneous transmission occurs.

  However, the document (8) does not describe any computing technology that can meet the needs of “the emergence of a method for preventing such erroneous transmission in advance”. Automatically creates and sends a transmission request message to send SMS to a large number of mobile phone numbers listed in the directory information while automatically preventing such erroneous transmission. It could not be processed.

  The computing method according to the present invention is implemented in a computing system named SMS distribution system. This SMS distribution system communicates with a computer of a business company or the like (client computer) that wants to distribute SMS to a large number of customers, etc. via the Internet, and the above-mentioned SMS transmission agent service system (SNS transmission) Communication via the Internet), and SMS transmission request messages are sent to the SMS transmission agent system based on the information received from the client computer, thereby realizing SMS distribution to a large number of customers. To do.

  The inventor of the present application focused on the fact that the date (time stamp) in which the information of each customer is written in the name list is recorded in the customer name list created by the business company. A customer record in the customer list contains the customer's mobile phone number and time stamp. The time stamp in this case can be regarded as the date corresponding to the date when the customer declared his / her mobile phone number to the company and the company posted the mobile phone number in the customer list. I will call it.

Based on the above, the core of the present invention is the computing method specified by the following items (1) to (10).
(1) The SMS distribution system should be able to access the number search history database. (2) The number search history database is a number check result when a number of predetermined digits that can be used as a mobile phone number is periodically checked. (3) Number survey results include the survey date, the number of the predetermined number of digits, and the number as the mobile phone number on the survey date. (4) The SMS distribution system communicates with the client computer requesting SMS distribution via the network, and the client identifier X and distribution list are associated with each other. Y is received, and based on this, number search processing, history verification processing, message creation processing, and message output processing are performed. (5) Distribution list Y is SM A plurality of records in which the mobile phone number A as the destination of the message, the number registration date B corresponding to the date on which the client received the number A, and the message number C are described (6) SMS distribution The system stores and manages the message collection pre-registered by the client, and when the client identifier, message number, and carrier identifier are specified, one message is specified from the message collection. (7) Number Investigation Processing Now, to pick up the phone number described in each record of the distribution list Y, and transmits a call setup message was unrestricted digital transmission capability to the mobile phone number a picked up with the called party number to the ISDN, the call In response to the disconnection message from the network, the mobile phone number A is valid / invalid based on the reason for the disconnect message and the description of the source (8) In the history verification process, the number search result for the mobile phone number A recorded in the history database is verified, and the mobile phone number is checked in the distribution list Y. If there is a number investigation result that is invalid in the number investigation history after the number registration date B associated with A for a predetermined period, do not perform message creation processing / message transmission processing. (9) Message creation In the processing, one message D specified by the client identifier X, the message number C associated with the mobile phone number A in the distribution list Y, and the carrier identifier of the mobile phone number A specified in the number search processing. Is picked up from the message collection, the picked up message D is designated as the transmission message, and the mobile phone number A is designated as the destination. (10) In the message transmission process, the SMS transmission request message is generated by communicating with the SMS transmission proxy system via the network and transmitting the SMS transmission request message generated by the message generation process. To do

  The client communicates with the SMS distribution system, conveys several types of fixed messages in advance, and registers them in the message collection. Then, when SMS distribution is performed, the distribution list is prepared in the client computer and transmitted to the SMS distribution system. After that, the SMS delivery system automatically sends SMS transmission request messages to the SMS transmission agent system in a fully automatic manner, whereby the SMS transmission agent system cooperates with the mobile phone carrier to implement the SMS distribution. Will be. Therefore, the work load on the client side is minimized.

  Since the SMS delivery system performs the history verification process prior to creating and sending an SMS transmission request message addressed to a certain mobile phone number, there is a possibility that the number subscriber has been changed without any human intervention. If it is determined that the value is high, measures are taken to prohibit SMS transmission.

An example of an embodiment for carrying out the present invention Procedure of history verification processing in one embodiment

=== Overview of SMS Distribution System ===
As shown in FIG. 1, the SMS distribution system according to one embodiment of the present invention includes a database server 1, a call investigation server 2, and a Web server 3. The Web server 3 communicates with the client computer 4 via the Internet. The Web server 3 communicates with the SMS transmission agent system 5 via the Internet.

The database server 1 stores and manages the aforementioned number search history database. The number investigation history database records number investigation results when a predetermined number of digits that can be used as a mobile phone number are regularly examined.

  The call investigation server 2 makes a call to ISDN for a predetermined number of digits that can be used as a mobile phone number, and examines the network response to investigate the use status of the number as a telephone number. The latest investigation result by the periodic call investigation is sequentially added to the number investigation history database in the database server 1.

  The number survey result recorded in the number survey history database includes information identifying the survey date, the number of the predetermined number of digits, and whether the number is valid or invalid as a mobile phone number on the survey date. It is associated. It is well known that there is a subcategory in the category of valid, and that there is a subcategory in the category of invalid, and in the present invention, it is not directly related to these subclasses. Will not be described. In addition, the number search result may include other information such as the identifier of the carrier (communication carrier) to which the number belongs for the number determined to be valid as the mobile phone number.

=== Number investigation and carrier determination ===
As explained in detail in Japanese Patent No. 2801969, a PC-class computer is connected to ISDN as an ISDN terminal, and whether it is used as a fixed telephone number is a 10-digit number as a called number, When a call setup message describing “unrestricted digital” is transmitted to the network, and the response from the network to the call is a disconnect message describing reason display number 3 (no route to the other party), it is described as a called number. The 10-digit number can be determined to be a number used as a fixed telephone number. At this time, the ringing bell of the called telephone is not ringed.

  As explained in detail in Japanese Patent No. 5265800, a call setup message from a computer connected to ISDN with the 11 digit number used as the mobile phone number as the called number and the transmission capability as "unrestricted digital" When a message is transmitted, a disconnect message is returned from the network, and the calling process for the mobile phone with the called number does not proceed.

The disconnect message from the network includes descriptions of “reason display” and “generation source”. The 11-digit number used as the mobile phone number is the called number, and the transmission capability is “unrestricted digital”. In the case of a disconnect message for a call setup message, the description of “reason display” and “generation source” differs for each telecommunications carrier (carrier), and the called party number is set according to the “reason display” and “generation source” in the disconnect message. The carrier to which the mobile phone number belongs can be determined. Specifically, it is as follows.
● NTT DOCOMO reason display = 69, generation source = 3
● SOFTBANK MOBILE reason display = 69, generation source = 4
● KDDI reason display = 3, generation source = 3

  In addition, for the call setting message in which the 11-digit number that is not used as the mobile phone number is the called number and the transmission capability is “unrestricted digital”, the above three types of “reason display” and “generation source” A message different from the described disconnect message is returned from the network. Therefore, in response to a call setup message in which an 11-digit number that is unknown whether it is used as a mobile phone number is a called number and the transmission capability is “unrestricted digital”, the above three types of “ When a disconnect message describing either “reason indication” or “generation source” is returned from the network, the 11-digit number is determined to be the number used as the mobile phone number in the corresponding carrier. Good.

  Furthermore, immediately before this application, for example, the above-mentioned call setting message with the 11-digit number used as the mobile phone number of NTT Docomo as the called number and the transmission capability as “unrestricted digital” is described above. Thus, when a disconnect message of reason display = 69 and generation source = 3 returns from the network, it is considered that this may change in the future. Such cases have been observed in the past, and if such a change actually occurs, it can be recognized immediately, so it is easy to adapt subsequent criteria to the reaction information after the change. Can be dealt with.

=== Distribution list created on the client side ===
The client prepares a distribution list file described in the CSV format in the client computer 4. The distribution list includes a large number of records for each customer, and one record describes the following data.
(A) Mobile phone number A as the SMS destination
(A) Number registration date B corresponding to the date on which the client received the number A
(C) Message number C corresponding to the message text to be sent to the mobile phone with number A

  The client accesses the Web server 3 by the client computer 4, receives authentication by the login ID / password, and transmits the prepared CSV file of the distribution list to the Web server 3. As a result, the Web server 3 receives the client identifier X and the distribution list Y from the client computer 4.

=== Messages ===
The Web server 3 stores and manages a collection of messages sorted by client identifier on the hard disk. A message grouped by a plurality of message numbers is described in the message collection for each client. The content of the message is different for each message number. For example, message number 1 is a message that says "How are you? Please send a blank e-mail to ***" and message number 2 is "Your payment is now complete. The message is “Waiting for you”.

  However, as a message corresponding to one message number, a message whose expression / description is optimized for each carrier (communication carrier) can be registered. In summary, the Web server 3 has a logical structure in which when a client identifier, a message number, and a carrier identifier are specified for a message collection, one message in the message collection is specified.

=== Number check processing ===
The Web server 3 cooperates with the database server 1 and the call investigation server 2 to perform number investigation processing / history verification processing / message creation processing based on the client identifier X and the distribution list Y received from the client computer 4. -Perform message output processing.

  First, in the number checking process, the mobile phone number described in each record of the distribution list Y is picked up, and a call setting message with the picked up mobile phone number A as the called number and the transmission capability as non-restricted digital is sent to ISDN. A disconnect message from the network for the call is received, and based on the display of the reason for the disconnect message and the description of the generation source, the validity / invalidity of the mobile phone number A is determined and, if valid, the carrier is specified. Of course, the process for creating and transmitting the SMS transmission request message is not performed for the invalid number.

=== Number verification processing ===
Assume that in the number search process, it is determined that the number A is valid as a mobile phone number and the carrier is specified. Next, the Web server 3 collaborates with the database server 1 to verify the number search result for the mobile phone number A recorded in the history database.

  An example of the number verification processing procedure is shown in FIG. In the series of history of the number investigation results for number A, first, the record of the investigation date nearest (newer side) to the number registration date B associated with the number A in the distribution list Y is picked up and examined. Here, it is assumed that the picked-up number survey result is valid. In this case, the counter C is set to zero, and the record before one (new side) of the series of records is picked up. If the picked-up record is valid, the counter C is set to zero and the new record is picked up one by one to check validity / invalidity.

  If the picked-up record is invalid, the counter C is incremented and a new record is picked up. If a record of invalidity appears six times in this process, the value of the counter C becomes 6, and the processing ends at this point. This indicates that the number A is currently valid as a mobile phone number, but there has been an invalid state for six months or more in the period from the number registration date B of the number A to the present. In this case, since there is a high possibility that the number contractor has been changed, transmission of SMS addressed to the mobile phone number A is prohibited. That is, for the mobile phone number A, the process for creating and transmitting the SMS transmission request message is not performed.

=== Message creation process ===
The SMS transmission system performs the number search process / number verification process as described above based on the distribution list Y and simultaneously performs the message creation process / message transmission process. It is assumed that the above long-term invalid period does not exist for the mobile phone number A. In this case, the Web server 3 performs, as the message creation process, the client identifier X, the message number C associated with the mobile phone number A in the distribution list Y, and the carrier of the mobile phone number A specified in the number search process. One message D specified by the identifier is picked up from the message collection, the picked up message D is designated as a transmission message, the mobile phone number A is designated as a destination, and a predetermined format including the carrier identifier is included. An SMS transmission request message is created and temporarily stored in the memory.

=== Message transmission processing ===
The Web server 3 transmits an SMS transmission request message to the SMS transmission proxy system 5. The electronic message includes information on the transmission side (such as authentication information of the SMS distribution system). The SMS transmission request message received by the SMS transmission proxy system 5 is a message requesting SMS transmission of one message to one mobile phone number. The Web server 3 transmits a message to the SMS transmission proxy system 5 each time one SMS transmission request message is generated in the message generation process.

  Each time the SMS transmission proxy system 5 receives an SMS transmission request message, the SMS transmission proxy system 5 works on the carrier backbone system corresponding to the carrier identifier in the message, and describes the message in the message on the mobile phone with the mobile phone number in the message. Will be sent.

=== Notify the client that SMS transmission is stopped ===
The Web server 3 records the execution result of the above-described message transmission process on the hard disk, and when the client computer 4 accesses the Web server 3 and requests to view the distribution record, a report in a predetermined format indicates whether SMS transmission is correct or not. This is provided to the client computer 4 as a screen. In addition to this report function, the Web server 3 determines that the number contractor is likely to have been changed by the history verification process, and for the mobile phone number for which no SMS transmission request has been made, the client computer 4 is provided with a function for browsing a dedicated report for informing that.
