Description

  The present invention provides a short message for enabling more companies to send and receive short messages between a mobile phone terminal of a carrier that provides each mobile phone service and a company that provides various information by short messages. About the system.

  Currently, mobile phone terminals provided by carriers that provide mobile phone services generally have a short message service (hereinafter sometimes referred to as “SMS (Short Massage Service)”) function. Here, the carrier is a communication carrier classified as a first-class telecommunications carrier having communication equipment such as a line network, and NTT, KDDI, and the like correspond to this. In addition, SMS is a service for transmitting a mail by designating a telephone number as a destination between mobile phone terminals provided by the same carrier. For example, NTT (docomo) provides an SMS named short mail, and KDDI (au) provides an SMS named C mail. The number of characters that can be transmitted and received by SMS mail is about 100 single-byte characters, which is smaller than e-mail (E-mail) that is transmitted by designating a mail address. However, since SMS mail is data that is transmitted using the control channel of the mobile phone's telephone line, it has better real-time performance than e-mail (e-mail) and the other party received the mail. Since it is possible to confirm this, it has already been implemented in many countries (for example, see Patent Document 1).

  A system has been proposed in which a company provides information that changes from moment to moment, such as stock information, to users who have mobile phone terminals by utilizing the feature of SMS that has real-time characteristics (for example, Patent Documents). 2).

JP 2010-34928 A JP 2009-105908 A

  However, when these companies use a server capable of sending and receiving SMS and provide information and services using real-time SMS, a special mobile phone terminal is assigned to the server. A phone number, for example, a shorter number of digits (eg, 3 digits or 4 digits) than a normal phone number, and a specific starting number or disclosure symbol (eg, #) is used. Due to the small number, it was impossible to assign special telephone numbers to many companies, and there was a problem that many companies could not do it even if they wanted to provide information and services.

  The present invention has been made paying attention to such problems, and a short-circuit that allows more companies to provide information and services by using a special telephone number assigned to a server. An object is to provide a message system.

In order to solve the above-mentioned problem, a short message system according to claim 1 of the present invention provides:
A short message service server installed in a carrier that provides a short message service using a mobile phone terminal, and a server having a short message transmission / reception function with the mobile phone terminal, which is operated by a plurality of companies A short message system including a server computer that mediates a short message transmitted and received between the mobile phone terminal and the enterprise server,
The server computer
A company keyword storage means for storing company identification information capable of specifying each company to which a single common destination number is assigned and a keyword related to the company in association with each other;
When receiving a short message of the common destination number for from the short message service server, a destination specifying means for specifying the destination of enterprise short message thus received,
Short message transmitting means for transmitting the received short message to a company server of the company specified by the transmission destination specifying means;
Determination means for determining whether or not a keyword related to a company stored in the company keyword storage means is included in the received short message from the short message service server;
An elapsed time management means for managing the elapsed time from the transmission of one short message between the mobile phone terminal and the enterprise server of the enterprise in an identifiable manner;
With
When the determination unit determines that the received short message includes a keyword related to a company stored in the company keyword storage unit, the transmission destination specifying unit associates the company keyword with the keyword. A company specified from the company specifying information stored in the storage means is specified as a destination company of the received short message, and is stored in the company keyword storage means in the received short message by the determination means. If it is determined that none of the keywords related to a company are included, if the elapsed time from transmission of one short message specified by the elapsed time management means is within a predetermined period, the specified 1 The company corresponding to the short message of the destination of the received short message To identify as a business
It is characterized by that.
According to this feature, since the company included in the short message identifies the company to which the short message is transmitted, a plurality of companies (for example, group companies) use the same common destination number. As a result, more companies can provide information and services while using the telephone number assigned to the company server.

A short message system according to claim 2 of the present invention is the short message system according to claim 1,
The server computer
The fact that the short message cannot be transmitted to the mobile phone terminal that has transmitted the short message when the transmission destination of the received short message from the short message service server is not specified by the transmission destination specifying means It is characterized by the provision of error short mail replying means to reply the error short mail.
According to this feature, when the keyword is not stored, the destination cannot be specified, that is, when the short message cannot be sent to the destination, an error short mail is returned, so the sender of the short message sent It is possible to quickly confirm that the short message has not arrived at the destination.

Short message system of claim 3 of the present invention, there is provided a short message system of the placing serial to claim 2,
The error short mail reply means replies an error short mail including each keyword stored in the company keyword storage means in association with the company specifying information of each company to which the common destination number is assigned. .
According to this feature, since the error short mail that is returned contains the correct keyword corresponding to the common destination number of the short message sent by the user, the user can accurately grasp the correct keyword. Therefore, the occurrence of inconvenience due to repeated transmission of a short message including an erroneous keyword can be largely avoided.

The short message system according to claim 4 of the present invention is the short message system according to any one of claims 1 to 3,

A short message of a predetermined protocol for sending / receiving a short message to / from the enterprise server from a carrier message of the carrier transmitted from the mobile phone terminal of the carrier via the short message service server of each carrier A first protocol conversion process for converting to a first message, a carrier that is a destination of a short message transmitted from each of the enterprise servers, and a short message of the predetermined protocol as the carrier protocol used in the identified carrier And a second protocol conversion process for converting the second protocol conversion process.
According to this feature, a short message of each carrier protocol transmitted from the mobile phone terminal of each carrier is converted into a short message of a predetermined protocol and transmitted to the corporate server, and a short of the predetermined protocol transmitted from the corporate server. Since the message is converted into a short message according to each carrier protocol and transmitted, each company server does not need to create and send a short message according to the carrier protocol of each carrier individually. Irrespective of the short message of a predetermined protocol, the short message can be easily transmitted and received with the mobile phone terminal of each carrier.

A short message system according to claim 7 of the present invention is the short message system according to claim 6,

  The form for implementing the short message system based on this invention is demonstrated below based on an Example. In the following embodiment, SMS is used as the name of the short message.

  FIG. 1 is a system diagram showing a configuration of a short message system of the present embodiment to which the present invention is applied. The short message system includes a protocol conversion server 1 and a data management server 2 having a gateway database (GW-DB) installed in the SMS gateway service center. The SMS gateway service center includes a mobile phone service. Carrier server A, carrier B company, carrier C company, which are first-class telecommunications carriers that provide information, and company servers 6 (6a) of company A, company B, company C, etc. that provide information by SMS , 6b, 6c) are connected.

  The protocol conversion server 1 and the data management server 2 are connected so as to be able to exchange data with each other, and these two servers cooperate to provide each function of the gateway for the short message service.

  In FIG. 1, only three carriers, Carrier A, Carrier B, and Carrier C, are shown as carriers. However, the present invention is not limited to this, and these carriers include at least two carriers. I just need it. The carrier may be a carrier that provides a service of a simple mobile phone (PHS).

  1 illustrates companies A to C, but the present invention is not limited to this, and there may be four or more companies as long as there are a plurality of these companies.

  As shown in FIG. 1, each carrier is connected to each mobile phone via a base station 4 (4a, 4b, 4c) that performs wireless communication with the mobile phone terminals 5 (5a, 5b, 5c) belonging to each carrier. An SMS server 3 (3a, 3b, 3c) for sending and receiving SMS to and from the terminal 5 (5a, 5b, 5c) is installed and is intended for the mobile phone terminal 5 (5a, 5b, 5c) in the same carrier Are distributed and distributed by the SMS server 3 of each carrier, and the SMS for other carriers is not shown corresponding to the destination carrier from the SMS server 3 (3a, 3b, 3c) of each carrier. After being converted into the SMS protocol of the destination carrier by the carrier gateway server, it is transmitted to the SMS server 3 (3a, 3b, 3c) of the destination carrier.

  The SMS server 3 (3a, 3b, 3c) of each carrier is associated with the data for delivering the SMS, specifically, the mobile phone numbers of the mobile phone terminals 5a, 5b, 5c belonging to the carrier. In addition, an SMS database storing SIM data, location data, and the like is stored.

  The SMS database also includes a server special SMS phone number (a special phone number with a few digits beginning with #) assigned to the company server 6 (6a, 6b, 6c) as the SMS destination phone number. Data stored in correspondence with the special SMS telephone number and indicating that the SMS destination for the special SMS telephone number is the SMS service center, specifically, the network address of the protocol conversion server 1, etc. Is remembered.

  Therefore, the SMS addressed to a single special SMS number assigned to each company server 6 is transmitted from the SMS server 3 (3a, 3b, 3c) to the SMS service center (3a, 3b, 3c) with respect to the protocol conversion server 1 with the protocol of each carrier. Sent to the protocol conversion server 1).

  In the following description, when the carriers A, B, and C are not specified, the mobile phone terminals 5a, 5b, and 5c may be collectively referred to as the mobile phone terminal 5, and similarly, the base station 4a, 4b and 4c may be collectively referred to as the base station 4, and the SMS servers 3a, 3b, and 3c may be collectively referred to as the SMS server 3.

  Further, as shown in FIG. 1, enterprises A to C are provided with enterprise servers 6 (6a, 6b, 6c) connected to the protocol conversion server 1 so that data communication is possible. , 6b, 6c) has an SMS function for sending and receiving SMS to and from the protocol conversion server 1 using a short protocol peer-to-peer protocol (SMPP).

  As shown in FIG. 2 (a), the data management server 2 of the present embodiment is used for distributing SMS transmitted from the mobile phone terminals 5 (5a, 5b, 5c) of each carrier to each company. A database (FIG. 2 (b)) and a gateway database (GW-DB) used to distribute SMS transmitted from each company to the mobile phone terminals 5 (5a, 5b, 5c) of each carrier are stored. ing.

  As shown in FIG. 2A, the gateway database (GW-DB) of this embodiment stores an individual database for each company (company). Specifically, a gateway database for company A (GW-DB), a gateway database for company B (GW-DB), and a gateway database for company C (GW-DB) are stored.

  In the distribution database used in the present embodiment, as shown in FIG. 2 (b), keywords relating to a distribution company uniquely assigned to each distribution company (company), a distribution company name, and an SMS session Are stored in association with each other.

  In the example shown in FIG. 2B, a common special SMS telephone number “# XX1” is assigned to the group companies A to C. Company A is a company that provides information on the production area of agricultural products displayed at supermarkets and department stores. The keyword of the company is stored as “production area confirmation”. It is a company that provides traffic information such as obstacles, and “Traffic Information” is stored as a keyword of the company, and Company C is a company that provides flight information of airplanes. "Guidance" is stored.

  That is, as the “keyword” in the distribution database, a keyword related to information and services provided by each company, that is, a keyword related to each company may be registered.

  Further, as will be described later, when the SMS is transmitted again from the mobile phone terminal 5 (5a, 5b, 5c) after one SMS exchange (transmission / reception) has occurred, The period during which the same company as the previous SMS is determined as the transmission destination without being inserted is stored. In other words, since the type and service of information provided by each company is different, it is only necessary to set (store) a session expiration date according to the type of information and service provided. For example, if it is traffic information or flight information, Since it is unlikely that SMS will be sent repeatedly over time, the session expiry date is set to a relatively short time (for example, 60 seconds). A relatively long time (for example, 180 seconds) may be set.

  Note that these session expiration dates are not limited to 60 seconds or 180 seconds shown in FIG. 2B, but the session expiration date of “1 day” or “one week”, as in the case of Company F, etc. It is good also as the session expiration date.

  Further, the configuration of the gateway database (GW-DB) of the present embodiment is as follows. As shown in FIGS. 3A and 3B, the mobile phone number assigned to the mobile phone number is associated with the mobile phone number. The type of carrier to which the telephone terminal 5 belongs (carrier A, carrier B, carrier C), the virtual mobile phone number with which the mobile phone number is replaced, the registration date and time (including the hour and minute) of the virtual mobile phone number, Since the SMS has recently been sent and received between the mobile phone terminal 5 (5a, 5b, 5c) of the mobile phone number and each company server 6 (6a, 6b, 6c), the destination is set to the gateway database ( GW-DB) stores data such as when a session expires, which is a period determined as a corresponding company.

  The virtual mobile phone number is a unique number that does not overlap in the gateway database (GW-DB) of the company, and the mobile phone number and the virtual mobile phone number are associated one-to-one.

  However, in FIG. 3 (a) and FIG. 3 (b), for example, as shown in the case of the mobile phone number “090XXXXXX”, the virtual phone that differs for each company with respect to the same mobile phone number “090XXXXXX” is shown. The mobile phone number is stored.

  That is, the same mobile phone number may be stored in the gateway database (GW-DB) for each company, but the virtual mobile phone number corresponding to these same mobile phone numbers is stored for each company. By being individually assigned in the gateway database (GW-DB), different virtual mobile phone numbers are assigned and stored for each company.

  The session expiration time is also updated based on the session expiration date set individually for each company in the distribution database shown in FIG. Specifically, when an SMS is sent / received between a mobile phone number or a virtual mobile phone number and a company server corresponding to the gateway database (GW-DB), the corresponding in the distribution database is determined from the time at that time. The time when the session expiration date of the company has passed is specified, and the time is updated (that is, the time when the session expiration date of the company is added to the time at that time).

  In addition, the data management server 2 stores the erasure condition table shown in FIG. 3C, and the erasure that the virtual cellular phone number stored in the gateway database (GW-DB) for each company is erased. Conditions are stored and set individually for each company.

As these erasure conditions, specifically, as shown in FIG. 3C, for example, conditions relating to the elapsed time since the virtual mobile phone number is stored (registered) may be set. Depending on the company, When the stored (registered) virtual mobile phone number is used without being erased, “no erasure” may be stored as in the company C, for example.

  Next, the protocol conversion process 1 performed by the protocol conversion server 1 in response to receiving the SMS from the SMS server 3 will be described with reference to FIG. 4. First, in the protocol conversion process 1, the protocol conversion server 1 has received The SMS telephone number of the SMS transmission destination is extracted (step S1).

  Then, it is determined whether or not the extracted SMS phone number is a special SMS phone number to be distributed. If it is not a special SMS phone number, the process proceeds to step S6, whereas if it is a special SMS phone number, Proceeding to step S3, all keywords stored in the sorting database in association with the special SMS phone number are extracted, and it is determined whether or not any of the extracted keywords is included in the SMS.

  If any of the extracted keywords is included in the SMS, the process proceeds to step S5, and the distribution destination company stored in the distribution database in association with the keyword included in the SMS is stored in the SMS. The transmission destination is specified and the process proceeds to step S6.

  On the other hand, if “No” in the determination in step S4, that is, if any of the extracted keywords is not included in the SMS, the process proceeds to step S11 and is stored in the distribution database in association with the special SMS phone number. In the company gateway database (GW-DB) of each company, all session expiration times stored in association with the mobile phone number of the sender of the SMS are specified, and among the specified session expiration times, It is determined whether or not there is a session expiration time for which the time of the time has not yet passed (step S12).

  If there is a session deadline when the current time has not yet elapsed, that is, SMS is exchanged immediately between the company server 6 of the special SMS phone number and the mobile phone terminal 5 of the source mobile phone number. If the elapsed time from the point in time within the session expiration date set for the company is within the session expiration date set for the company, the company corresponding to the company gateway database in which the session expiration time that has not yet passed is registered (Step S13), the process proceeds to step S6.

  On the other hand, if all the session deadlines have passed, the process proceeds to step S14, and each stored in the distribution database in association with the special SMS telephone number extracted in step S3. An error SMS including all of the keywords is created, the created error SMS is returned to the mobile phone number of the transmission source (step S15), and the process ends.

  Further, in step S6 which shifts from step S6 and step S13 described above, various data corresponding to the SMPP including the mobile phone number of the transmission source are extracted from the received SMS.

  Next, it is determined whether or not the mobile phone number extracted in step S6 is already stored in the gateway database (GW-DB) of the destination company specified in step S5 or step S13 (step S7).

  Specifically, if the destination company is company A, it is determined whether or not the mobile phone number extracted in step S6 is already stored in the gateway database (GW-DB) for company A. To do.

  If the extracted mobile phone number has already been registered, the process proceeds to step S8, and the virtual mobile phone stored in the gateway database (GW-DB) in association with the registered mobile phone number. Extract phone numbers.

  Then, the process proceeds to step S9, and the time at which the session expiration date stored in the distribution database is added in association with the destination company specified at step S5 or step S13 is specified. Then, the session time limit update process is executed to update and store the specified time at the session time limit.

  Then, the virtual telephone number extracted in step S8 and each data extracted in step S6 are applied to the corresponding SMPP data to generate SMPP data, and the generated SMPP data is identified in step S5 or step S13. The information is transmitted to the previous company (step S10).

  On the other hand, if the extracted mobile phone number is not stored in the gateway database (GW-DB) for the destination company specified in step S5 or step S13, it is determined as “No” in step S7, and the step Proceeding to S21, a virtual telephone number registration process for storing a virtual telephone number corresponding to the mobile phone number in association with the mobile phone number is performed.

  In this virtual telephone number registration process, first, a virtual telephone number unique to the company is generated. As a method for generating these unique virtual telephone numbers, it may be generated from a mobile phone number based on a conversion rule assigned to each company, or an arbitrary number may be generated using a random number or the like. It is sufficient to search for whether or not the generated number overlaps with a virtual telephone number that has already been registered, and use one that has been identified as not overlapping (no storage of the same number).

  The virtual telephone number generated in this way is stored (registered) in association with the mobile telephone number in the gateway database (GW-DB) for the destination company, and date / time data (including the hour and minute) at the time of registration. ) And the carrier type and the like are stored, the process proceeds to step S9, and the above-described session time limit update process is performed.

  Then, the process proceeds to step S10, where the newly generated virtual telephone number and each data extracted in step S6 are applied to the corresponding data of SMPP to generate SMPP data, and then the generated SMPP data is specified in step S5. Send to the company.

  Thereby, in the converted SMPP data, the mobile phone number included in the received SMS is replaced with the virtual phone number.

Next, the protocol conversion process 2 performed by the protocol conversion server 1 in response to receiving the SMS from the company server 6 will be described with reference to FIG. 5. First, in the protocol conversion process 2, the protocol conversion server 1 transmits The original company is specified (step Sb1).

  The sender company may be specified from the network address of the sender of the received SMS data.

  Then, each data including the destination virtual telephone number is extracted from the received SMPP data (Step Sb2), and the extracted virtual telephone number is stored in the gateway database (GW-DB) for the source company. It is determined whether or not.

  When the virtual telephone number is stored in the gateway database (GW-DB) for the transmission source company, “Yes” is determined in step Sb3 and the process proceeds to step Sb4 to identify the carrier corresponding to the virtual telephone number. To do.

  Specifically, the carrier type stored in association with the virtual telephone number may be extracted and specified in the gateway database (GW-DB) for the transmission source company.

  Then, after updating the corresponding session deadline by performing the above-described session deadline update process (step Sb4 +), each data extracted in step Sb2 is applied to the specified carrier protocol and the virtual telephone number is set. Then, after replacing the mobile phone number stored in association with the virtual phone number and generating protocol data corresponding to the carrier of the transmission destination (Sb5), the generated carrier-corresponding protocol data is transmitted in step Sb4 It transmits with respect to the SMS server 3 of the specified carrier (step Sb6).

  If “No” is determined in step Sb3, that is, if the virtual telephone number is not stored in the gateway database (GW-DB) for the transmission source company, the process proceeds to step Sb7, where the transmission source An error reply process for transmitting an error SMS including a message indicating that the destination telephone number is incorrect is performed on the company server 6 and the process ends.

  When the protocol conversion server 1 executes the protocol conversion process 1 and the protocol conversion process 2, the SMS is transmitted from the mobile phone terminal 5 to the enterprise server 6 and the SMS is transmitted from the enterprise server 6 to the mobile phone terminal 5. The flow performed will be described with reference to FIG.

  For the user carrying the mobile phone terminal 5, a special SMS phone number and a keyword assigned to each company (company) are notified by television, radio, advertisement, or the like, for example.

  When an SMS containing a keyword is transmitted to the special SMS telephone number announced by the user of the mobile phone terminal 5, the SMS addressed to the special SMS telephone number is transmitted to the protocol conversion server 1 (gateway) by the SMS server 3. Center) is identified and transmitted to the protocol conversion server 1 (gateway center).

  In the protocol conversion server 1, the above-described protocol conversion processing 1 is performed, whereby the company server 6 of the company corresponding to the keyword is specified as a transmission destination and is based on a carrier protocol including an actual mobile phone number. The SMS is converted into an SMS based on SMPP including the virtual mobile phone number and transmitted to the specified destination company server 6, whereby the SMS reaches each company.

  Then, in response to the reception of the SMS from the user of the mobile phone terminal 5, when the SMS of the information provided by the company is returned to the received virtual mobile phone number, the returned SMS is transmitted to the protocol conversion server 1. Is done.

  Then, by performing the protocol conversion processing 2 described above in the protocol conversion server 1, the SMS based on the SMPP including the virtual mobile phone number is converted into the SMS based on the carrier protocol including the actual mobile phone number and transmitted. It is transmitted to the SMS server 3 installed in the previous carrier.

  In response to receiving the SMS of its own carrier protocol transmitted from the protocol conversion server 1, the SMS server 3 transmits the SMS to the mobile phone terminal 5 having the actual mobile phone number included in the SMS. As a result, the SMS from each company server 6 reaches the mobile phone terminal 5.

  Note that the data management server 2 of this embodiment periodically performs a gateway database (GW-DB) update process shown in FIG. 7 at predetermined time intervals.

  In the gateway database (GW-DB) update process of the present embodiment, the data management server 2 first specifies an erasure condition corresponding to the gateway database (GW-DB) to be updated (step Sc1).

  Specifically, if the gateway database (GW-DB) to be updated is the gateway database (GW-DB) of company A, it is stored corresponding to company A in the erasure condition table of FIG. If the erasing condition is extracted and specified, and if it is the gateway database (GW-DB) of company B, the erasing condition stored corresponding to company B is extracted in the erasing condition table of FIG. If the gateway database (GW-DB) of company C is specified, the deletion conditions stored corresponding to company C are extracted and specified in the deletion condition table of FIG.

  Then, all virtual telephone numbers that satisfy the specified erasure condition are extracted from the gateway database (GW-DB) to be updated (step Sc2).

  Next, it is determined whether or not there is a virtual telephone number that satisfies the erasure condition, that is, whether or not there is an extracted virtual telephone number, and if it exists, storage (registration) of the extracted virtual telephone number is performed. (Step Sc4) On the other hand, if there is no extracted virtual telephone number, the process proceeds to step Sc5 without going through step Sc4.

  In step Sc5, it is determined whether or not the update process has been performed for all gateway databases (GW-DB). If not, the next gateway database (GW-DB) is set as an update target, and the step is performed. Return to Sc1.

  By doing so, data such as a virtual telephone number that satisfies the erasure condition and an actual mobile phone number corresponding to the virtual telephone number are erased from the gateway database (GW-DB) of each company. Therefore, the storage capacity required for storing the gateway database (GW-DB) can be reduced, and in this embodiment, these erasure conditions can be set for each company in accordance with the business form of each company. Therefore, it is preferable that the storage capacity of the gateway database (GW-DB), which is a virtual telephone number storage means, can be avoided, but the present invention is not limited to this. These erasure conditions may be the same for all companies.

  Even if these erasure conditions are not satisfied, the data of each gateway database (GW-DB) is stored in the company corresponding to each gateway database (GW-DB), for example, when information leakage such as a virtual telephone number occurs. For example, by deleting all data in the gateway database (GW-DB) corresponding to the company, it is possible to prevent annoying SMS due to illegal use of the leaked virtual telephone number.

  As described above, according to this embodiment, the SMS destination company is specified by the keyword included in the SMS, so that the same special number in which a plurality of companies, for example, group companies, are common destination numbers. Since the SMS phone number can be used, more companies can provide information and services while using the special SMS phone number assigned to the company server.

  Further, according to the present embodiment, when no keyword is included in the SMS, an error SMS is returned, so that the sender of the SMS can quickly confirm that the transmitted SMS has not arrived at the destination. Can be confirmed.

  Further, according to the present embodiment, since the error SMS returned to the sender of the SMS includes a correct keyword corresponding to the SMS special SMS telephone number transmitted by the user, the user can Since the correct keyword can be accurately grasped, inconvenience due to repeated transmission of the SMS including the wrong keyword, for example, the occurrence of unnecessary increase in the SMS transmission fee in the user. It can be largely avoided.

  Further, according to the present embodiment, when the elapsed period from the occurrence of one short message is within the session expiration period, the transmission destination is specified even if no keyword is included. Therefore, when the exchange of short messages is repeatedly performed between the mobile phone terminal 5 and the company server 6, the user of the mobile phone terminal 5 does not have to insert a keyword into the short message every time. The convenience of the user of the mobile phone terminal 5 can be improved.

  In the present embodiment, also in the protocol conversion process 2 that is performed when SMS is transmitted from the company server 6 to the mobile phone terminal 5, the update process at the time of session expiration in step S9 described above is performed, The session expiration time is updated, but the present invention is not limited to this, and the session expiration time update processing may be performed only by the protocol conversion processing 1.

  In addition, according to the present embodiment, in the distribution database, the session expiration date is stored for each company, so that the session expiration date corresponding to the difference in information and service provision form in each company can be set. However, the present invention is not limited to this, and these session expiration dates may be shared by each company.

  In addition, according to the present embodiment, the SMS of each carrier protocol transmitted from the mobile phone terminal 5 of the carrier is converted into the SMS of the SMPP as a predetermined protocol and transmitted, and the SMPP transmitted from each company server 6 is transmitted. SMS is converted into a short message according to each carrier protocol and transmitted, so that each company does not have to create a short message for each carrier protocol individually, and the SMS gateway service center (protocol conversion server) It is possible to easily send and receive a short message to / from the mobile phone terminal 5 of each carrier simply by connecting to 1) and creating only the SMS of SMPP.

  Further, according to the present embodiment, in the protocol conversion process 1, since the mobile phone number is replaced with the virtual mobile phone number and the SMS data of SMPP is generated, the mobile phone number of the caller mobile phone terminal 5 is changed to the individual mobile phone number. Since it becomes possible to mediate SMS without being understood by the company (company), for example, while the importance of telephone numbers is increasing due to number portability, the mobile phone of the sender is caused by the leakage of information from individual companies It is possible to prevent the terminal phone number from being leaked.

  Further, according to the present embodiment, the virtual mobile phone number and the mobile phone number are stored in association with each other, and in the protocol conversion process 2, the virtual mobile phone number is replaced with the actual mobile phone number and the destination carrier protocol is transmitted. Therefore, SMS can be transmitted (returned) from each company while preventing the mobile phone number of the source mobile phone terminal 5 from being grasped by each company.

  In addition, according to the present embodiment, the registration of the virtual telephone number to each gateway database (GW-DB) is automatically performed in the protocol conversion 1 on the condition that the mobile telephone number is not registered. It is not necessary to previously store the mobile phone number of the mobile phone terminal 5 of each carrier and the virtual phone number corresponding to the phone number in each gateway database (GW-DB), and in these gateway databases (GW-DB) Not only can the stored data capacity be reduced to the minimum necessary, but also the trouble of storing these mobile phone numbers and virtual phone numbers can be remarkably saved.

  In addition, according to the present embodiment, individual virtual telephone numbers are stored and used for each company, so even if a virtual telephone number leaks from each company, the virtual telephone numbers used by these companies Even if the password is invalidated (erased), the virtual telephone numbers used in other companies can be used as they are, and the damage caused by the outflow of these virtual telephone numbers can be reduced.

  Although the embodiments of the present invention have been described with reference to the drawings, the specific configuration is not limited to these embodiments, and modifications and additions within the scope of the present invention are included in the present invention. It is.

  For example, in the above-described embodiment, for all SMS, replacement with a virtual telephone number is performed in protocol conversion, but the present invention is not limited to this. For companies, replacement with virtual telephone numbers is performed, but for company B, replacement with virtual telephone numbers is set for each company, such as not performing replacement with virtual telephone numbers. You may be able to do it.

Moreover, in the said Example, although the protocol between each company server 6 was made into the same SMPP, this invention is not limited to this, The protocol between these companies can also be set as protocols other than SMPP. Moreover, a specific company may use a separate protocol from other companies.

  Moreover, in the said Example, when a virtual telephone number is leaked, it has illustrated erasing as a method of invalidating this leaked virtual telephone number, but this invention is limited to this Rather, by assigning a new second virtual telephone number to these leaked first virtual telephone numbers, and changing these first virtual telephone numbers to second virtual telephone numbers and using them, By using the second virtual telephone number while invalidating the first virtual telephone number, even a company that has leaked information may be able to continue providing services.
