<First embodiment>
[Overview of message relay device 1]
FIG. 1 is a diagram illustrating an overview of a message relay system S according to a first embodiment. The message relay system S is a system for exchanging messages. The message relay system S includes a message relay device 1, a message distribution device 2, and an information terminal 3.

The message relay device 1 is a device for transmitting and receiving messages to and from the message distribution device 2 and the information terminal 3. The message relay device 1 is, for example, a message gateway.

The message is, for example, a message exchanged based on RCS (Rich Communication Service) or SMS (Short Message Service), but is not limited thereto. The message may include one or more action buttons indicating possible reaction options for the user. When the user selects an action button, the information terminal 3 performs processing associated with the selected action button. The process associated with the action button is for the message associated with the action button to be returned to the sender, or for the information terminal 3 to activate a predetermined function.

The message distribution device 2 is a device that distributes messages distributed by companies that provide content and services to users, or receives messages addressed to companies. The message distribution device 2 transmits a request to send a message to the user to the message relay device 1, or acquires from the message relay device 1 a message sent from the user to the company. The same company may distribute messages from multiple message distribution devices (2A, 2B).

The information terminal 3 is a terminal used by a user who is a consumer of content and services provided by a company. The information terminal 3 sends and receives messages and displays the received messages. The information terminal 3 accepts the user's operation and transmits a message associated with the action button selected by the user to the message relay device 1. The information terminal 3 is, for example, a smartphone, a tablet, or the like.

By the way, when a reply message is received, the message relay device 1 can link the received reply message and the message to which the reply message is a reply based on the message ID (Identification) included in the message. . Here, the message ID is information that identifies the message. However, since the message that is replied when the action button is pressed includes a message ID that is different from the message that is the target of the reply, the message relay device 1 determines whether the reply message is the target of the reply or not based on the message ID. It is not possible to specify the message to be sent.

Therefore, the message relay system S according to the embodiment transmits a message configured such that information for identifying the message delivery device 2 (for example, device ID) is included in the message returned when the user selects an action button. do. Then, the message delivery device 2 is identified based on the device ID included in the received reply message.

The flow of processing in the message relay system S will be described below. The message relay device 1 receives a message distribution request from the message distribution device 2A ((1) in FIG. 1). A message delivery request includes corporate identification information (e.g., account information) of the company sending the message, user identification information (e.g., phone number, user ID, or email address) of the company to which the message is sent, the body of the message, and one or more options (choices). A, option B) included. The message relay device 1 generates an association option that associates the received option with identification information (device A) that identifies the message delivery device 2 ((2) in FIG. 1). The identification information for identifying the message distribution device 2 is, for example, a device ID or an IP address of the device. The association option is, for example, an action button configured to, when operated, send a message including the option associated with the device ID. The message relay device 1 transmits a message including one or more action buttons for selecting an association option to the information terminal 3 ((3) in FIG. 1).

The message relay device 1 receives a message including an association option (for example, option A (device A)) sent by the user selecting an action button included in the message ((4) in FIG. 1). Based on the device ID (device A) included in the received association option, the message delivery device 2A as the notification destination is specified ((5) in FIG. 1). The message relay device 1 notifies the message distribution device 2A specified based on the device ID of the option selected by the user ((6) in FIG. 1).

In this way, the message relay device 1 transmits a message including options associated with the device ID of the message distribution device 2 to the information terminal 3, and sends a notification based on the device ID included in the reply message received from the information terminal 3. Specify the message distribution device 2 that should be used. By configuring the message relay device 1 in this way, it is possible to notify the device that should receive the reply message received from the user.

[Configuration of message relay device 1]
FIG. 2 is a block diagram showing the configuration of the message relay device 1 according to the embodiment. The message relay device 1 includes a distribution request receiving section 131 , a choice managing section 132 , a transmitting section 133 , a receiving section 134 , a notification section 135 , and a message managing section 136 . The communication unit 11 is a communication interface for transmitting and receiving data to and from other devices via a network.

The storage unit 12 is a storage medium including a ROM (Read Only Memory), a RAM (Random Access Memory), an SSD (Solid State Drive), a hard disk drive, and the like. The storage unit 12 stores in advance a program to be executed by the control unit 13.

The control unit 13 is, for example, a processor such as a CPU (Central Processing Unit). The control unit 13 functions as a distribution request receiving unit 131 , a choice management unit 132 , a transmitting unit 133 , a receiving unit 134 , a notification unit 135 , and a message management unit 136 by executing the program stored in the storage unit 12 .

The distribution request receiving unit 131 receives a message distribution request from the message distribution device 2 that includes a message destination, message contents, and options available to the destination user. The content of the message is, for example, a main text, an image, or information indicating a display mode thereof included in the message.

The "options" include "display content" and "reply content". “Display content” indicates the content displayed on the action button on the screen of the information terminal 3. "Reply content" indicates information included in a message that the information terminal 3 replies to the sender when the action button displayed on the screen of the information terminal 3 is pressed. An example where options are described in JSON (JavaScript Object Notation) is shown below.

"suggestions": [
{

"reply": {
"displayText": "Yes",
"postback": {
"data": "answer_YES"

}
}
},
{

"reply": {
“displayText”: “No”,
"postback": {
“data”: “answer_No”

}
}
}
]

In the above, "reply" indicates a unit of options, and "display text" and "postback" indicate "display content" and "reply content", respectively. In the above example, a string of "Yes" is displayed, and an action button indicating that the character string "answer_YES" will be returned when operated, and an action button that displays a string of "No" and an action button that indicates that the string of "answer_NO" will be returned when operated. ” is displayed as an option.

The option management unit 132 generates an association option that associates the option included in the received message delivery request with the device ID of the message delivery device 2. The option management unit 132 generates an association option that associates the "reply content" with the device ID of the message distribution device 2 that has transmitted the message distribution request in association. For example, the option management unit 132 may generate an association option in which the device ID is associated as part of the parameters included in the "reply content." An example of association options generated by the option management unit 132 in this case is shown below. Note that in the following example, "origin" is a parameter indicating the device ID.

"suggestions": [
{

"reply": {
"displayText": "Yes",
"postback": {
"data": "answer_YES"
"origin: "SYSA01"

}
}
},
{

"reply": {
“displayText”: “No”,
"postback": {
"data": "answer_No"
"origin: "SYSA01"

}
}
}
]

The transmitting unit 133 transmits a message including message contents and association options to a destination. The sending unit 133 sends a message to the destination identification information included in the message delivery request. FIG. 3 is a diagram illustrating an example of a message transmitted by the transmitter 133. The message shown in FIG. 3 includes sender information C1, message content C2, and action button C3. The sender information C1 is information indicating the company that sent the message delivery request. The action button C3 is displayed based on the association options generated by the option management section 132.

When the user presses the action button C3 displayed on the information terminal 3, the information terminal 3 transmits a message corresponding to the selected action button to the message relay device 1. Then, the receiving unit 134 receives the message sent when the destination user selects the association option. The message received by the receiving unit 134 includes an association option corresponding to the action button selected by the user. An example of association options included in the received message is shown below.

"response": {
"reply": {
"displayText": "Yes",
"postback": {
"data": "answer_YES"
"Origin": "SYSA01"

}
}
},

The notification unit 135 notifies the message distribution device 2 corresponding to the device ID included in the association options included in the received message of the options included in the received message. The notification unit 135 identifies the message delivery device 2 to which the received option is to be notified based on the device ID included in the received association option. Then, the notification unit 135 notifies the specified message distribution device 2 of the received option.

By configuring the message relay device 1 in this way, it is possible to notify the device that should receive the reply message received from the user.

By the way, the message relay device 1 may generate association options in various ways. As an example, the option management unit 132 may generate an association option by including an identification ID as a parameter of the option included in the message delivery request. Specifically, the option management unit 132 generates an association option in which the device ID is associated by adding information that identifies the message delivery device 2 to the value of the "reply content" parameter in the option. An example of association options generated by the option management unit 132 in this case is shown below.

"suggestions": [
{

"reply": {
"displayText": "Yes",
"postback": {
"data": "SYSA01_answer_YES"

}
}
},
{

"reply": {
“displayText”: “No”,
"postback": {
“data”: “SYSA01_answer_No”

}
}
}
]

An example of the reply message that the receiving unit 134 receives from the information terminal 3 in this case is shown below.

"response": {
"reply": {
"displayText": "Yes",
"postback": {
"data": "SYSA01_answer_YES"
}
}
},

By configuring the message relay device 1 to generate association options in this way, it is possible to send messages without increasing the types of parameters to be sent to the information terminal 3, and the information terminal 3 can perform unintended operations. This can be prevented.

By the way, if the relationship between a company's account information and the message delivery device 2 used by the company is uniquely determined, the message delivery device 2 can be specified based on the account information. Therefore, the message relay device 1 may be configured to generate association options when the relationship between the company's account information and the message distribution device 2 cannot be uniquely determined.

The option management unit 132 generates an association option when the sender account of the message delivery request is a predetermined account, and the option manager 132 generates an association option when the sender account of the message delivery request is not the predetermined account. Without doing so, the transmitting unit 133 transmits a message including the content and options to the destination. The predetermined account is an account that uses a plurality of message distribution devices 2. For example, the storage unit 12 stores a list of accounts that use a plurality of message distribution devices 2. Then, if the source account of the received message delivery request is included in the list stored in the storage unit 12, the option management unit 132 generates an association option.

Further, the storage unit 12 or an external device (not shown) may manage the account and the message distribution device 2 to which the account is logged in. Then, the option management section 132 is configured to inquire of the storage unit 12 or the external device about the login status of the sender account of the received message, and if the account is logged in to multiple servers, the option management unit 132 is configured to generate association options. Good too.

When the option management unit 132 notifies the message delivery device 2 of the device ID of the message delivery device 2 associated with the option, the message delivery device 2 may perform an unintended operation. Therefore, the option management unit 132 generates an option by deleting the device ID included in the association option included in the received message, and notifies the transmitting unit 133 of the option. That is, when the item indicating the option and the item indicating the device ID are associated, the option management unit 132 deletes the item indicating the device ID, extracts the item indicating the option, and notifies the transmitting unit 133. If the information indicating the option and the device ID are embedded in the item indicating the option, the option management unit 132 deletes the part indicating the device ID and notifies only the information indicating the option.

In this way, the message relay device 1 can prevent unintended operation of the message delivery device 2 by deleting the device ID included in the returned message and notifying the user of the options.

Furthermore, the message relay device 1 needs to notify the message delivery device 2, which sent the message delivery request, of the message transmission status. Note that the transmission status is information indicating, for example, that the transmission of the message has been completed (referred to as a transmission completion notification), that the message has arrived (referred to as an arrival notification), or that the message has been opened (referred to as an opening notification).

Specifically, the message management unit 136 associates the message ID of the message sent by the sending unit 133 with the device ID of the message delivery device 2 that sent the message delivery request, and stores them in the storage unit 12. FIG. 4 is a diagram showing an example of the data structure of the message ID table stored in the storage unit 12. In the message ID table, the message ID of the transmitted message is associated with the device ID of the message distribution device 2 that transmitted the distribution request for the message.

The information terminal 3 then transmits the transmission status of the received message to the message relay device 1 in association with the message ID of the received message. The receiving unit 134 receives the transmission status including the message ID transmitted by the information terminal 3.

When the receiving unit 134 receives the transmission status including the message ID of the transmitted message, the notification unit 135 transmits the transmission status to the message distribution device 2 corresponding to the device ID associated with the message ID included in the transmission status. to notify you of this. When the notification unit 135 receives the message transmission status, it acquires the device ID corresponding to the message ID included in the message transmission status in the message ID table. Then, the notification unit 135 notifies the message distribution device 2 corresponding to the device ID that the transmission status has been received.

By configuring the message relay device 1 in this way, it is possible to notify the message transmission status to the message distribution device 2 that has transmitted the message distribution request.
