In general, when a web service provider performs membership registration related to mobile phone web services provided to mobile terminal users, it is necessary to verify the identity of mobile terminal users in order to correctly perform membership registration, distribution of free points, and billing. (Individual identification) is widely performed.

Especially for social service providers such as social networking services (SNS) and social games, due to the nature of the service, in order to prevent the acquisition of multiple accounts by the same person and spoofing by a third party, 1 It is necessary to secure the principle of one account for each portable terminal (one user), and for that purpose, user identification (individual identification) is required.

Conventionally, as a method for identifying a user, individual identification information, which is a unique number assigned to each mobile phone, has been mainly used.

However, unlike conventional mobile phones, there are also models in which so-called smartphones do not send individual identification information. Further, depending on the application of the smartphone, it may be possible to transmit the individual identification information by impersonating (spoofing). For this reason, with the spread of smartphones, it is difficult to identify users using conventional individual identification information.

As an individual identification method that can be used on both conventional mobile phones and smartphones, a service provider that has received an SMS transmission request from a user terminal sends an SMS mail including an authentication ID to a unique mobile phone number assigned to each user terminal. There is a method in which the user who transmits and receives the SMS mail inputs the authentication ID and transmits it to the service provider to confirm the identity of the user.

It is not done.

(First embodiment)
First, an SMS mail transmission system and method according to a first embodiment of the present invention will be described with reference to the drawings.

In the SMS mail transmission system and method according to the first embodiment of the present invention, a service provider sends an SMS mail including an authentication ID to a user terminal, and the authentication ID included in the SMS mail received by the user is sent to its own terminal. This can be used when the user ID is verified by comparing the authentication ID sent from the service provider with the authentication ID sent back from the user terminal.

Referring to FIG. 1, the SMS mail transmission system 1000 according to the first embodiment of the present invention includes a gateway system (GW system) 14, a user terminal 16, and an operator terminal 20. The GW system 14 includes a gateway server (GW server) 10 and an SMS database (SMSDB) 12.

The GW server 10 is a server of this service provider. In order for the user to receive the service provided by the service provider, the user may need to receive identity verification by the service provider. Therefore, first, the user having the user terminal 16 accesses the GW server 10 via the Internet using the user terminal 16 in order to receive the service of the present service provider. When the user terminal 16 accesses the GW server 10, an SMS mail for confirming the identity is transmitted to the user terminal 16.

The SMSDB 12 is a database in which information related to SMS mail transmitted by the service provider to the user terminal is recorded.

The GW system 14 is a system that includes the GW server 10 and the SMSDB 12. The GW system 14 may be a system for a service provider to provide the service to the user terminal, in addition to performing identity verification.

The user terminal 16 is a portable terminal that is a transmission destination of the SMS mail transmitted by the service provider. The user terminal 16 is a terminal device that can be connected to the Internet, such as a mobile phone or a smartphone. It can also be connected to a line service network provided by a mobile phone operator and can receive SMS mail.

The provider terminal 20 is a portable terminal that transmits an SMS mail transmitted by the service provider to the user terminal 16. A plurality of business operator terminals 20 may be provided, and may be arbitrarily added according to the quantity of SMS mails to be transmitted. The operator terminal 20 can be connected to a line service network provided by the mobile phone operator in the same manner as the user terminal 16. Thereby, the SMS mail can be transmitted to the user terminal 16. Further, the business entity terminal 20 may be connected to the Internet or the like. For example, a wireless LAN connection may be possible. As will be described later, a special application is installed in the business operator terminal 20 and can access the GW system via the Internet, a wireless LAN, or the like. Further, the operator terminal 20 may be able to access the GW system via a line service network provided by the mobile phone operator. In this case, the operator terminal 20 does not need to be connectable to the Internet or the like.

The business operator terminal 20 is preferably installed in the same country as the user terminal 16. However, if SMS mail can be transmitted from the operator terminal 20 to the user terminal 16 from overseas using roaming or the like, the operator terminal 20 is installed in a country different from the location of the user terminal 16. Also good. The GW system 14 may be installed anywhere as long as it can communicate with the user terminal 16 through the Internet. For example, the GW system 14 may be installed in a country different from where the user terminal 16 is located.

Referring to FIG. 2, the GW server 10 includes an SMS transmission request reception unit 21, an authentication ID generation unit 22, an SMS transmission unit 23, an SMS transmission result determination unit 24, an SMSDB reading unit 25, an SMS failure log management unit 26, and an authentication ID reception. -The collation part 27 is included.

Referring to FIG. 2, the SMSDB 12 includes an SMS transmission server log table 31 and an SMS failure log table 32. The SMSDB 12 further includes other tables such as an SMS transmission log table (not shown) for recording data mainly for key performance indicator (KPI) of the service provider such as the OS type of the user terminal. May be included.

Referring to FIG. 3, the user terminal 16 includes an SMS transmission request transmission unit 41, an SMS reception unit 42, and an authentication ID input / transmission unit 43.

Referring to FIG. 4, the operator terminal 20 includes an SMSDB reading unit 51, an SMS transmission unit 52, an SMS failure log deletion command unit 53, and an SMS transmission number control unit 54. A special application is installed in the operator terminal 20, and the SMSDB reading unit 51, the SMS transmission unit 52, the SMS failure log deletion command unit 53, and the SMS transmission number control unit 54 are all controlled by the application.

The SMS mail transmission system 1000 according to the first embodiment of the present invention will be described in detail with reference to FIGS. 1 and 2 again.

The SMS transmission request reception unit 21 of the GW server 10 receives the SMS transmission request transmitted from the SMS transmission request transmission unit 41 of the user terminal 16 via the Internet. The SMS transmission request may include the telephone number of the caller user terminal 16 and information associated with the telephone number. The telephone number of the user terminal 16 is used as a destination for sending SMS mail later.

The authentication ID generation unit 22 of the GW server 10 generates an authentication ID for each SMS transmission request. The authentication ID may be any number or character information provided by the service provider for verifying the identity of the user. Since the authentication ID is given to confirm the identity of the user, it is preferable that a different authentication ID is generated for each SMS transmission request. For example, an authentication ID may be generated by generating a random number for each SMS transmission request.

The SMS transmission unit 23 of the GW server 10 transmits an SMS mail to the user terminal 16 that has transmitted the SMS transmission request. The SMS mail transmitted by the SMS transmission unit 23 is a mail for transmitting the generated authentication ID to the user terminal.

The SMS transmission result determination unit 24 of the GW server 10 determines whether or not the SMS transmission unit 23 has successfully transmitted the SMS mail.

For each SMS transmission request received from the user terminal 16, the GW server 10 records information related to SMS mail transmission in the SMS transmission server log table 31 of the SMSDB 12. Information related to SMS mail transmission recorded in the SMS transmission server log table 31 includes, for example, the SMS transmission request reception date and time, the telephone number of the user terminal of the SMS mail transmission destination, the authentication ID included in the SMS mail, the SMS mail transmission date and time, the SMS mail. A transmission result or the like may be included. The result of determination by the SMS transmission result determination unit 24 may be included in the SMS mail transmission result. For example, the result of determination such as success or failure of SMS mail transmission may be included.

The SMSDB reading unit 25 of the GW server 10 reads information recorded in the SMS transmission server log table 31 of the SMSDB at regular intervals, for example. The SMSDB reading unit 25 may read information recorded in the SMS transmission server log table 31, for example, once a minute. When the SMS mail transmission result indicating that the SMS mail transmission has failed is recorded in the SMS transmission server log table 31, the SMSDB reading unit 25 displays the information regarding the telephone number of the transmission destination and the authentication ID that failed in the transmission. The information is acquired and recorded in the SMS failure log table 32. Hereinafter, the information regarding the telephone number and the authentication ID recorded in the SMS failure log table 32 is referred to as “SMS failure log”.

The SMSDB reading unit 51 of the business entity terminal 20 periodically accesses the GW system 14 and reads the SMS failure log when the SMS failure log is recorded in the SMS failure log table 32. The SMSDB reading unit 51 may read whether the SMS failure log is recorded in the SMS failure log table 32, for example, once every 10 seconds. The SMS transmission unit 52 of the operator terminal 20 includes an authentication ID included in the SMS failure log with a telephone number (for example, a telephone number included in the SMS failure log) acquired based on the acquired SMS failure log as a transmission destination. Send SMS mail.

When the SMS transmission unit 52 of the business entity terminal 20 has successfully transmitted the SMS mail including the authentication ID included in the SMS failure log, the SMS failure log deletion command unit 53 of the business enterprise terminal 20 receives the GW system via the Internet or the like. 14 and instructs the SMS failure log management unit 26 of the GW server 10 to delete the failure log related to the SMS mail that has been successfully transmitted.

The SMS failure log management unit 26 that has received the SMS failure log deletion command from the provider terminal 20 deletes the failure log related to the SMS mail that has been successfully transmitted from the SMS failure log table 32.

The SMS receiving unit 42 of the user terminal 16 receives the SMS mail transmitted from the GW server 10 or the operator terminal 16. The user 18 may input the authentication ID included in the SMS mail to the user terminal 16 by the authentication ID input / transmission unit 43 of the user terminal 16 and send it back to the service provider. The reply of the message including the authentication ID by the authentication ID input / transmission unit 43 may be transmitted via the Internet.

The authentication ID reception / verification unit 27 of the GW server 10 receives the message transmitted from the authentication ID input / transmission unit 43 of the user terminal 16 and collates the authentication ID included in the received message with the transmitted authentication ID. .

When the authentication ID receiving / verifying unit 27 determines that the authentication ID included in the received message matches the transmitted authentication ID, the GW server 10 determines that the personal authentication of the user 18 has been completed, A service may be provided to the user terminal 16. If the authentication ID reception / verification unit 27 determines that the authentication ID included in the received message does not match the transmitted authentication ID, the GW server 10 may transmit an error message to the user terminal 16. Good.

With the above configuration, even when the GW server 10 fails to send the SMS mail to the user terminal 16, the SMS mail is sent again from the provider terminal 20 installed in the same country as the user terminal 16 to the destination where the transmission failed. Since it is transmitted, the SMS mail transmitted by the service provider can be surely received by the user terminal 16.

In addition, according to the configuration of the present invention, by installing an operator terminal in the same country as the user terminal, and installing and starting an application on the operator terminal, no other special infrastructure maintenance is required. In addition, the SMS can be received more reliably by the user terminal.

The business entity terminal 20 may include an SMS transmission number control unit 54. The SMS transmission number control unit 54 counts the number of SMS mails sent by the operator terminal 20 in one day, and when the number of SMS mails sent by the operator terminal 20 reaches a certain number, the SMS of the day Stop sending mail. For example, when the upper limit of the number of SMS transmissions set for each carrier is 200 / day, the SMS transmission number control unit 54 sets the number of SMS mails transmitted by the operator terminal 20 to 180. May be set per day. Thereby, the SMS transmission operation by the operator terminal 20 can be stopped before the upper limit.

As a result, the carrier terminal 20 is prevented from exceeding the upper limit of the SMS mail transmission number set by the carrier, and when the upper limit of the SMS mail transmission number is exceeded, the carrier terminal 20 is locked by the carrier. Can be avoided. Even when SMS mail transmission of a certain company terminal 20 is stopped by the SMS transmission number control unit 54, if there is another company terminal 20, there is a response to the user terminal described in the failure log by the other company terminal. SMS mail transmission can be performed.

According to the configuration of the present invention, by increasing the number of business operator terminals, the number of SMS mails to be transmitted to the user terminal can be easily increased without requiring other facilities and infrastructure. In addition, the operator terminal can be manufactured by installing the above-described special application on a terminal that is normally sold.

In addition, when the authentication ID reception / verification unit 27 has not received a reply message from the user terminal 16 at a time when a certain time has elapsed from the date and time when the SMS transmission request is received from the user terminal 16, the GW server 10 The SMS failure log management unit 26 of the server 10 acquires information on the telephone number of the transmission destination of the user terminal 16 and the transmitted authentication ID from the SMS transmission server log table 31, and uses these as failure logs as the SMS failure log table. 32 may be stored. The SMS failure log management unit 26, for example, when the reply message is not received from the user terminal 16 at the time when 30 minutes have elapsed from the date and time when the SMS transmission request is received, The number and the transmitted authentication ID may be stored in the SMS failure log table 32.

As described above, even when a reply message is not received from the user terminal 16 when a certain time has elapsed from the date and time when the SMS transmission request is received, the transmission destination is recorded as a failure log, whereby the SMS transmission result determination unit 24 is recorded. Even if the SMS mail transmission from the GW server 10 has actually failed, the SMS failure log management unit 26 does not recognize that the transmission has failed. Since the information regarding the number and the authentication ID is stored in the SMS failure log table 32, the SMS ID can be notified by transmitting an SMS mail from the business operator terminal 20.

Even if the GW server 10 has succeeded in SMS mail transmission, the SMS mail is left unopened in the user terminal, or the user has forgotten to enter the authentication ID. There is a case where the authentication ID is not input and returned from the user terminal. In such a case, by recording the transmission destination as a failure log even when a reply message is not received from the user terminal 16 when a certain time (for example, 3 hours) has passed since the date and time when the SMS transmission request was received. Since the SMS mail including the same authentication ID as that already sent from the business operator terminal 20 can be transmitted again, the probability that the authentication ID is input and returned from such a user terminal can be improved. .

In order to prevent excessive SMS transmission to users who do not intentionally enter and transmit authentication IDs, SMS mail by the operator terminal 20 after a certain period of time has elapsed since the date and time when the above SMS transmission request was received. The retransmission may not be repeated until the authentication ID is input, but only once for the same SMS transmission request.

Further, when the SMS transmission request receiving unit 21 receives the SMS retransmission request again from the user terminal 16 that has transmitted the SMS transmission request, the authentication ID generating unit 22 obtains a new authentication ID in response to the retransmission request. Generate. Then, the SMS failure log management unit 26 stores the telephone number of the user terminal that has transmitted the retransmission request and the new authentication ID without using the SMS transmission unit 23 of the GW server 10 as a failure log in the SMS failure log table. May be.

Thus, by sending SMS mail from the operator terminal 20 without sending SMS mail from the GW server 10 to the user terminal that wants to re-send SMS mail, the user terminal can be more reliably and rationally transmitted. Can receive SMS mail.

The SMS mail transmission process according to the present embodiment will be described with reference to FIG. FIG. 10 is a flowchart showing the overall flow of SMS mail transmission processing according to the present embodiment.

Referring to FIG. 10, in step 300, the GW server receives an SMS transmission request from a user terminal.

In step 302, the GW server generates an authentication ID for each received SMS transmission request.

If the received SMS transmission request is the first SMS transmission request transmitted from the user terminal, in Step 304, the telephone number of the user terminal is transmitted from the SMS transmission unit of the GW server or the SMS transmission server. The SMS mail including the authentication ID generated as is transmitted.
