Returning to FIG. 2, the generation unit 444 associates the generated delivery status screen with the message ID and stores it in the storage unit 43. Further, the generation unit 444 inputs the sender address information for accessing the delivery status screen, including the message ID, into the information transmission unit 445.

In the information transmission unit 445, after the message distribution unit 443 distributes the SMS message to each of the plurality of receiving terminals 2, the message distribution unit 443 distributes the SMS message to each of the plurality of receiving terminals 2 via the first communication unit 41. The sender address information for accessing the delivery status screen displaying the delivery status of the above is transmitted to the transmission terminal 1. The information transmission unit 445 may transmit the sender address information to the transmission terminal 1 and the plurality of reception terminals 2 specified by the specific unit 442. In this way, the information transmission unit 445 transmits the sender address information to the plurality of receiving terminals 2, so that the receiver using the receiving terminal 2 can grasp to whom the SMS message is delivered. can.

The information transmission unit 445 is a sender when the notification acquisition unit 446, which will be described later, acquires the delivery result notification from at least one receiving terminal 2 among the plurality of receiving terminals 2 to which the message distribution unit 443 has delivered the SMS message. The address information may be transmitted to the transmission terminal 1. In the information transmission unit 445, for example, after the generation unit 444 generates the delivery status screen, the notification acquisition unit 446, which will be described later, has at least one of the plurality of receiving terminals 2 to which the message distribution unit 443 has delivered the SMS message. The sender address information may be transmitted to the transmitting terminal 1 at the timing when the delivery result notification is acquired from the receiving terminal 2.

Further, the information transmission unit 445 transmits the sender address information to the transmission terminal 1 when the notification acquisition unit 446 acquires the delivery result notification from all the reception terminals 2 to which the message distribution unit 443 has delivered the SMS message. You may. The information transmission unit 445, for example, is the timing at which the notification acquisition unit 446 acquires the delivery result notification from all the receiving terminals 2 to which the message distribution unit 443 has delivered the SMS message after the generation unit 444 generates the delivery status screen. Then, the sender address information may be transmitted to the transmission terminal 1.

Further, the information transmission unit 445 may transmit the sender address information to the transmission terminal 1 at the timing when the generation unit 444 generates the delivery status screen, for example. Specifically, first, in the generation unit 444, the notification acquisition unit 446, which will be described later, acquires the delivery result notification from at least one receiving terminal 2 among the plurality of receiving terminals 2 to which the message distribution unit 443 has delivered the SMS message. When you do, a delivery status screen is generated. Then, the information transmission unit 445 may transmit the sender address information to the transmission terminal 1 at the timing when the generation unit 444 generates the delivery status screen. In this way, the information transmission unit 445 transmits the sender address information to the transmission terminal 1 at the timing when the delivery result notification is acquired, so that the sender has changed the delivery status of the SMS message. Can be recognized.

The notification acquisition unit 446 acquires a delivery result notification indicating that the SMS message has been received from the receiving terminal 2 via the first communication unit 41. The delivery result notification includes a message ID corresponding to the SMS message received by the receiving terminal 2 and a telephone number of the receiving terminal 2. When the notification acquisition unit 446 acquires the delivery result notification, the notification acquisition unit 446 updates the status of "delivery" stored in the status management database in association with the message ID included in the acquired delivery result notification and the telephone number of the receiving terminal 2. Let me.

By the way, when the receiving terminal 2 does not receive the SMS message, the SMSC 3 transmits the undelivered factor information indicating the factor that the SMS message could not be received to the message management device 4. The "factor for not being able to receive the SMS message" is, for example, the case where the receiving terminal 2 is in a call, the case where the receiving terminal 2 is out of the service area, the case where the communication equipment is faulty, the case where the reception is rejected, and the like.

Therefore, the generation unit 444 may generate a delivery status screen including further information on undelivered factors. Specifically, first, the notification acquisition unit 446 acquires undelivered factor information indicating the reason why the receiving terminal 2 could not receive the SMS message delivered by the message distribution unit 443 from the SMSC 3. Then, the generation unit 444 generates a delivery status screen that displays the delivery status based on the delivery result notification and the non-delivery factor information. By doing so, the sender can grasp the delivery status of the receiving terminal 2 and the reason why the receiving terminal 2 could not receive the SMS message.

Subsequently, the notification acquisition unit 446 acquires a browsing notification indicating that the user of the receiving terminal 2 has viewed the delivered SMS message from the receiving terminal 2. The browsing notification includes a message ID corresponding to the SMS message received by the receiving terminal 2 and a telephone number of the receiving terminal 2.

The notification acquisition unit 446 may acquire a browsing notification from the receiving terminal 2 by various methods. The notification acquisition unit 446, for example, indicates that the receiving terminal 2 has accessed the address indicated by the recipient address information for notifying that the SMS message has been viewed, which is included in the delivered SMS message, as a browsing notification. You may get it.

Specifically, first, the message distribution unit 443 distributes the SMS message including the recipient address information to the plurality of receiving terminals 2 specified by the specific unit 442. The recipient address information includes the message ID of the SMS message and the telephone number of the receiving terminal 2. When the receiving terminal 2 accesses the message management device 4 based on the address indicated by the recipient address information included in the SMS message, the notification acquisition unit 446 sets the message ID included in the receiver address information and the receiving terminal 2 to the message ID. Get the phone number and.

Further, the notification acquisition unit 446 may acquire the browsing notification transmitted from the receiving terminal 2 by executing the notification command included in the SMS message, for example. The notification command is a command for sending a browsing notification, which is executed when an SMS message is displayed in the SMS application.

Specifically, first, the message distribution unit 443 distributes an SMS message including a notification command for transmitting a browsing notification, which is executed when the SMS message is displayed, to a plurality of receiving terminals 2 specified by the specific unit 442. do. When the receiving terminal 2 displays the received SMS message in the SMS application, the receiving terminal 2 executes the notification command included in the SMS message and transmits the browsing notification to the message management device 4. Then, the notification acquisition unit 446 acquires the browsing notification transmitted by executing the notification command on the receiving terminal 2.

When the notification acquisition unit 446 acquires the browsing notification, the notification acquisition unit 446 updates the status of "browsing" stored in the status management database in association with the message ID included in the acquired browsing notification and the telephone number of the receiving terminal 2.

When the transmission terminal 1 accesses based on the address indicated by the sender address information, the Web access control unit 447 acquires the message ID included in the sender address information. The Web access control unit 447 transmits the delivery status screen stored in the storage unit 43 in association with the acquired message ID to the transmission terminal 1. Then, the Web access control unit 447 causes the display of the transmission terminal 1 to display a delivery status screen that displays the delivery status stored in the status management database in association with the message ID included in the sender address information.

The Web access control unit 447 may display the delivery status screen updated by the generation unit 444 based on the delivery result notification or the browsing notification on the display of the transmission terminal 1. Specifically, first, the generation unit 444 generates the notification information when the notification acquisition unit 446 acquires at least one of the delivery result notification and the browsing notification after the delivery status screen is generated. Update the delivery status screen based on. Then, the Web access control unit 447 transmits the delivery status screen updated by the generation unit 444 to the transmission terminal 1, and causes the display of the transmission terminal 1 to display the delivery status screen displaying the delivery status based on the notification information.

[Resend function]
The retransmission function is a function of re-delivering the SMS message to a plurality of receiving terminals 2 that have delivered the SMS message. In the example shown in FIG. 4, it is assumed that the sender performs an operation of checking the check box in the "selection" column corresponding to Mr. C and pressing the resend execution button on the delivery status screen.

In this case, the operation receiving unit 448 accepts the operation of re-delivering the SMS message displayed in the "message" column to the receiving terminal 2c used by Mr. C via the second communication unit 42. Then, the message distribution unit 443 uses the SMS message displayed in the "message" on the delivery status screen via the first communication unit 41 by Mr. C corresponding to the check box checked in the "selection" column. Redeliver to the receiving terminal 2c.

The message distribution unit 443 may re-deliver the SMS message to one or more receiving terminals 2 for which the delivery result notification has not been acquired, based on the information regarding the set retransmission process. The information regarding the retransmission process is, for example, a retransmission interval (for example, once an hour), a number of retransmissions, a retransmission date and time (for example, the first day of each month), a retransmission end time (for example, until 17:00), and the like.

Specifically, first, the operation reception unit 448 receives an operation for setting the SMS message retransmission process on the delivery status screen via the second communication unit 42. Then, the message distribution unit 443 does not acquire the delivery result notification based on the information regarding the set retransmission process after the SMS message is distributed to the plurality of receiving terminals 2 via the first communication unit 41. Redeliver the SMS message to one or more receiving terminals 2.

It is assumed that the operation reception unit 448 has received, for example, an operation of setting the retransmission interval to once an hour as an operation of setting the retransmission processing of the SMS message on the delivery status screen. In this case, after the SMS message is delivered to the plurality of receiving terminals 2, the message distribution unit 443 takes one hour to acquire the delivery result notification from one or more receiving terminals 2 that have not acquired the delivery result notification. Redeliver the SMS message at one interval.

The message distribution unit 443 may re-deliver the SMS message to one or more receiving terminals 2 that are not within the predetermined range from the predetermined position. For example, suppose that the sender sets the location (address) of the company as a predetermined location.

In this case, first, the message distribution unit 443 acquires the position information of each of the one or more receiving terminals 2 for which the delivery result notification has not been acquired. The message distribution unit 443 acquires, for example, the location information of each of the one or more receiving terminals 2 for which the delivery result notification has not been acquired from the HLR (not shown) that manages the location information of the communication terminal. Then, the message distribution unit 443 does not have the position indicated by the position information corresponding to each of the one or more receiving terminals 2 for which the delivery result notification has not been acquired within a predetermined range (for example, within 100 meters) from the location of the company. The SMS message is delivered again to one or more receiving terminals 2. By doing so, the message distribution unit 443 can narrow down to the receiving terminal 2 not in the company and retransmit the SMS message.

By the way, the timing at which the receiving terminal 2 that has not received the SMS message becomes able to receive the SMS message differs depending on the factor that the SMS message could not be received. For example, when the receiving terminal 2 cannot receive the SMS message due to a call, or when the receiving terminal 2 cannot receive the SMS message due to being out of the service area, the timing at which the former can receive the SMS message is set. It can be early.

Therefore, the message distribution unit 443 may re-deliver the SMS message to one or more receiving terminals 2 for which the notification acquisition unit 446 has not acquired the delivery result notification at the timing based on the undelivered factor information. For example, when the factor indicated by the undelivered factor information corresponding to the receiving terminal 2 that did not receive the SMS message is "in a call", the message distribution unit 443 has the receiving terminal 2 at an earlier timing than "out of service area". Redeliver the SMS message to. Further, for example, when the factor indicated by the undelivered factor information corresponding to the receiving terminal 2 that did not receive the SMS message is "out of service area", the message distribution unit 443 receives the SMS message at a later timing than "during a call". The SMS message is delivered to the terminal 2 again.

On the delivery status screen, the message delivery unit 443 is one or more receiving terminals 2 for which the notification acquisition unit 446 has not acquired the delivery result notification based on the retransmission timing set for each factor indicated by the undelivered factor information. In addition, the SMS message may be delivered again. In this way, the message distribution unit 443 can improve the probability that the receiving terminal 2 receives the SMS message by retransmitting the SMS message at the timing based on the undelivered factor information.

Even if the message delivery unit 443 determines whether or not to deliver the SMS message again to one or more receiving terminals 2 for which the notification acquisition unit 446 has not acquired the delivery result notification based on the undelivered factor information. good. Specifically, first, the message distribution unit 443 determines whether or not the factor indicated by the undelivered factor information is a factor that may enable the SMS message to be received.

The message distribution unit 443 has, for example, an SMS message when the factor indicated by the undelivered factor information is a reception refusal set in the receiving terminal 2 or when the receiving terminal 2 does not have a function of transmitting / receiving an SMS message. It is judged that it is not a factor that can make it possible to receive.
