FIG. 2 is a diagram illustrating the functional configuration of the in-house application server 20 and the smart device 30. FIG. 3 is a diagram for explaining data stored in the smart device information management DB 21.

  As shown in FIG. 1, the communication system 1 according to the present embodiment includes an in-house mail server 10, an in-house application server 20, and a smart device 30 owned by an employee. The in-house application server 20 and the smart device 30 are connected via a push cloud 40 that provides a push notification service on a communication network. When the push notification service is not used, data is directly transmitted / received via the communication network.

  In the communication system 1 of the present embodiment, a BYOD application program for smart devices (hereinafter also referred to as “BYOD application”) is distributed to all employees in a company, and an in-house mail server 10 and an in-house application server 20 are installed on-premises. Has been. Here, when simultaneous delivery of new mail occurs in the company, the employee receives it as new information (push notification), and immediately opens the BYOD app of the smart device 30 and confirms the new mail at a considerable rate. A usage form will be described.

  The in-house mail server 10 is a server that manages mail to be distributed to employees. The internal mail server 10 requests a push notification of new arrival information from the internal application server 20 when an event for distributing mails to employees at the same time occurs. Further, the in-house mail server 10 transmits the acquired new arrival information to the in-house application server 20.

  The in-house application server (hereinafter also referred to as “in-house AP server”) 20 is a server that manages transmission and reception of mail and data between the in-house mail server 10 and the plurality of smart devices 30 based on the application program.

  As shown in FIG. 2, the in-house AP server 20 includes a smart device information management DB 21, a push transmission module 22, a smart device control module 23, a smart device request processing module 24, a smart device operation monitoring module 25), and a smart device group management module. 26 and a data division / delivery module 27.

  The smart device information management DB 21 is a database that manages information on the BYOD application. As shown in FIG. 3, the smart device information management DB 21 includes a terminal key, an operation state, an IP address, a request reception port, a group ID, a transfer combination flag, an application continuous use time, a network communication speed, and the number of requests transferred in the past hour. Manage etc.

  The push transmission module 22 executes a process for sending a push notification and a silent push notification.

  The smart device control module 23 issues a control command to the smart device 30 via the push transmission module 22.

  The smart device request processing module 24 collectively receives request requests (return access) from the smart device 30 and causes the data division sending module 27 to execute data division transmission processing.

  The smart device operation monitoring module 25 uses the operation response request silent push notification to monitor the operation status of the smart device 30 (BYOD application) at regular intervals. The smart device operation monitoring module 25 updates items related to the operation state of the smart device information management DB 21 based on the acquired latest information.

  The smart device group management module 26 divides a plurality of smart devices 30 equipped with a BYOD application into a plurality of groups in order to distribute transfer of request requests, and designates a smart device 30 serving as a transfer role for each group. In the present embodiment, as shown in FIG. 1, an example in which nine smart devices 30 are divided into two groups will be described. When the smart device group management module 26 transmits push notifications to all terminals at once, the smart device group management module 26 includes the IP address and the request reception port (port number) of the smart device 30 serving as the transfer role of the corresponding group in the notification content.

  The data division dispatch module 27 divides the new arrival information data (response data) transmitted to the smart device 30 into packets of the same size and sends them.

  The smart device 30 is an information terminal owned by an employee, and a BYOD application for smart devices is executed. In FIG. 2, one of the plurality of smart devices 30 is shown as a representative. Hereinafter, the smart device 30 is also referred to as a “terminal”.

  As shown in FIG. 2, the smart device 30 includes a push reception module 31, a server command reception module 32, a request transfer module 33, a request dispatch control module 34, and a data combination control module 35.

  The push reception module 31 receives the push notification and the silent push notification transmitted from the in-house AP server 20, and transfers the data to a corresponding processing module (described later).

  The server command reception module 32 receives the operation response request transmitted by the silent push notification from the in-house AP server 20, and transmits response data informing the in-house AP server 20 that it is operating. In addition, the server command reception module 32 receives a request reception start request transmitted by the silent push notification from the in-house AP server 20 and activates a request transfer module 33 (described later).

  The request transfer module 33 accepts request requests from other smart devices 30. The request transfer module 33 collects request requests received within a certain reception period and transfers them to the in-house AP server 20 in a lump.

  The request dispatch control module 34 controls the transmission destination of the request request according to the notification content of the new arrival information received from the in-house AP server 20. When the new arrival information received from the in-house AP server 20 includes the IP address and request reception port of the smart device 30 serving as a transfer role, the request dispatch control module 34 performs an asynchronous request request to the smart device 30 serving as the transfer role. (Return access) is issued. Further, if the received new arrival information does not include the IP address and request reception port of the smart device 30 serving as a transfer role, the request dispatch control module 34 directly accesses the in-house AP server 20 and issues a request request.

  When receiving a data packet of newly arrived information data from the in-house AP server 20 by the silent push method, the data combining control module 35 combines the data packets in order to restore the newly arrived information data.

  Next, the operations (1) to (5) executed by the in-house AP server 20 and the smart device 30 of the communication system 1 shown in FIG. 1 will be specifically described.

(1) Terminal operation monitoring processing and (2) Transfer combination selection and terminal grouping processing FIG. 4 is a sequence diagram of terminal operation management processing, transfer combination selection and terminal grouping processing. Here, the terminals serving as communication partners will be described as smart devices 30A and 30B. Further, it is assumed that the smart device 30B is selected as the transfer combination.

The in-house AP server 20 monitors the operation status of all terminals and distributes the transfer role dynamically to distribute the burst-like loopback access to the transfer role and keep the response in the network communication of the transfer role at a certain level. Change and group terminals.
In step S (hereinafter also referred to as “S”) 11 shown in FIG. 4, the smart device operation monitoring module 25 of the in-house AP server 20 transmits an operation response request silent push notification to each smart device at regular time intervals. The operation response request silent push notification is transmitted via the smart device control module 23.

  In S21, the server command reception module 32 of the smart device 30A receives the operation response request.

  In S22, the server command reception module 32 of the smart device 30A transmits response data notifying that it is operating. In the smart device 30B, since the BYOD application has not been activated, no response data is transmitted.

  In S12, the smart device operation monitoring module 25 of the in-house AP server 20 receives the response data from the smart device 30A. The smart device operation monitoring module 25 grasps the operation state of the terminal depending on whether the response data has been received within the time limit.

  In S31, the smart device operation monitoring module 25 of the in-house AP server 20 updates the following information regarding the smart device 30A in the smart device information management DB 21 (see FIG. 4) based on the response data from the smart device 30A. The terminal is identified by an application key.

Operational state: Information indicating whether the BYOD application of the terminal is operating or not activated.
IP address: Information for accepting request requests from other smart devices.
Request acceptance port: Information for accepting request requests from other smart devices.
-Network communication speed: Information necessary for selecting a terminal that will serve as a forwarding agent.
-Number of requests transferred in the past hour: Information necessary to select a terminal that will serve as a forwarding agent.

  In S32, the smart device operation monitoring module 25 of the in-house AP server 20 does not receive the response data from the smart device 30B within the time limit, and therefore updates the information related to the smart device 30B in the smart device information management DB 21. In addition, the smart device operation monitoring module 25 activates the smart device group management module 26 to reselect a terminal serving as a transfer role from the group.

  The smart device group management module 26 refers to the smart device information management DB 21, and “the operation state is online”, “the continuous use time is long”, “the network communication speed is fast”, “the number of request requests in the past one hour is small. ”And other conditions are selected to select a terminal serving as a forwarding role. The smart device group management module 26 may select a terminal that satisfies all the above-described conditions as a transfer role, or may select a terminal that satisfies one or more high priority orders as a transfer role. Here, it is assumed that the smart device 30A is selected instead of the smart device 30B as the terminal serving as the transfer combination. Note that the number of terminals selected as the transfer combination is not limited to one, and a plurality of terminals that satisfy the conditions may be selected as the transfer combination.

  The smart device group management module 26 determines the number of groups based on the reception limit number of terminals that serve as the selected transfer combination. When there are a plurality of terminals selected as transfer combinations, the number of groups is determined based on the number of terminals serving as transfer combinations and the limited number of reception of each terminal.

  The smart device group management module 26 equally divides the operating terminals other than the transfer role and the terminals where the BYOD application has not been activated, and designates one transfer role terminal previously selected for each group. According to this, since the terminals in the group issue a request request only to the transfer role terminal, the request transfer load in the transfer role terminal can be suppressed within a certain level.

  The smart device group management module 26 that has performed the transfer combination selection and terminal grouping process updates the following information in the smart device information management DB 21 for the terminal selected as the transfer combination (smart device 30A).

Operational state: Information indicating whether the BYOD application of the terminal is operating or not activated.
Group ID: information on the group to which the terminal belongs.
Transfer combination flag: Information indicating whether or not the terminal is a transfer combination terminal.

(3) New Arrival Information Push Notification Processing FIG. 5 is a sequence diagram of new arrival information push notification processing.
In S41 illustrated in FIG. 5, the in-house mail server 10 requests the in-house AP server 20 to notify the in-house AP server 20 of a new arrival information at the time when an event for delivering the mail to the employees at once occurs.

  In S51, the smart device group management module 26 of the in-house AP server 20 transmits a silent push notification of a request reception start request to the smart device 30A serving as a transfer role. The request reception start request is transmitted to instruct the transfer device smart device 30A to receive a request request from another terminal.

  In S <b> 61, the push reception module 31 of the smart device 30 </ b> A receives the request reception start request transmitted from the in-house AP server 20 by the silent push notification. The request reception start request includes the following information.

Instruction code: Instruction identifier.
-Reception timeout time: Maximum waiting time from the end of the last request reception process until the next request comes.

  In S62, the server command reception module 32 of the smart device 30A starts request reception processing from another terminal in the same group.

  In S52, the smart device group management module 26 of the in-house AP server 20 includes the information on the IP address and request reception port of the terminal serving as the forwarding role of the group to which each terminal belongs in one new mail to be transmitted. Create new information. Then, the smart device group management module 26 transmits push notifications to all terminals simultaneously through the push transmission module 22.

(4) Request Request Acceptance and Transfer Processing FIG. 6 is a sequence diagram of request request acceptance and transfer processing.
In S71 illustrated in FIG. 6, the push reception module 31 of the smart device 30A receives the new arrival information transmitted from the in-house AP server 20 by a push notification. When the user performs an operation for acquiring new arrival information, a process for updating the new arrival information (issue of a request request or the like) is started.

  In S72, the request dispatch control module 34 of the smart device 30A issues a request request. The request dispatch control module 34 holds the request request until the reception timeout time because the own terminal is a transfer function.

  In S81, the push reception module 31 of the smart device 30B receives the new arrival information transmitted from the in-house AP server 20 by a push notification.

  In S82, the request dispatch control module 34 of the smart device 30B issues a request request. The request dispatch control module 34 connects to the transfer role terminal (smart device 30 </ b> A) based on the IP address and request reception port of the transfer role terminal included in the new arrival information, and requests a new arrival information request. Send.

  In the request request acceptance and transfer process, the processes of S81 and S82 may be performed prior to the processes of S71 and S72, or may be performed in parallel with the processes of S71 and S72.

  In S73, the request transfer module 33 of the smart device 30A receives a request request from another terminal. A fixed request reception period is provided for reception of request requests.

  In S <b> 74, the request transfer module 33 of the smart device 30 </ b> A collects the request request issued by the own terminal and the request requests from other terminals received within the request reception period, and collectively transfers them to the in-house AP server 20. In the request transfer module 33, request request reception and transfer processing are performed asynchronously. The request transfer module 33 repeatedly executes request request reception and transfer processing every time the request reception period ends. The request transfer module 33 ends the request request receiving process and the transfer process if a new request request is not received from another terminal even after the request receiving period has passed since the end of the previous request request transfer process. To do.

  In S91, the smart device request processing module 24 of the in-house AP server 20 accepts a request request (return access) from the smart device 30A serving as a transfer role.

(5) Asynchronous Shipping Process for New Arrival Information Data FIG. 7 is a sequence diagram of the asynchronous shipping process for new arrival information data.
In S101 shown in FIG. 7, the data division dispatch module 27 of the in-house AP server 20 starts the new arrival information data dispatch process.

  In S <b> 102, the data division dispatch module 27 of the in-house AP server 20 requests the in-house mail server 10 to transfer newly arrived information data.

  In S <b> 111, the in-house mail server 10 acquires new arrival information data and transfers it to the in-house AP server 20.

  In S103, the data division dispatch module 27 of the in-house AP server 20 divides the newly arrived information data transferred from the in-house mail server 10 into a plurality of data packets of the same size, and sends a silent push notification to each terminal that has received the request request. Ship.

  In S121, when the data combination control module 35 of the smart device 30A recognizes one data packet of newly arrived information data, it starts reception processing of subsequent newly arrived information data. The data combination control module combines newly received data packets in order and restores newly arrived information data.

  In S122, when the data combination control module 35 of the smart device 30A receives all data packets, it displays a reception completion message on the screen.

  In S131, when the data combination control module 35 of the smart device 30B recognizes one data packet of newly arrived information data, it starts reception processing of subsequent newly arrived information data. The data combination control module combines newly received data packets in order and restores newly arrived information data.

  In S132, when all the data packets are received, the data combination control module 35 of the smart device 30B displays a reception completion message on the screen.

  Note that in the asynchronous shipping process of newly arrived information data, the processes of S131 and S132 may be performed prior to the processes of S121 and S122, or may be performed in parallel with the processes of S121 and S122.

As described above, according to the communication system 1 of the present embodiment, even if mail is delivered to a plurality of terminals all at once by push communication, the return access is only to the transfer role terminal, and therefore the internal AP server 20 The increase in the return access can be suppressed.
Further, since it is not necessary to add a server in order to cope with a bursty return access that occurs temporarily, it is possible to avoid waste of server installation costs and maintenance costs.

Here, the effect of reducing the number of servers will be described with a specific example.
For example, in a company with 5,000 employees, it is assumed that all employees return to the application server after simultaneous delivery of new mail to all employees occurs. Further, it is assumed that the simultaneous connection upper limit of one application server is 100 tps, and ten smart devices are assigned to one group.

・ When terminal grouping and transfer terminal are not selected (conventional example)
Number of return access from terminal: 5000
Number of application servers to support return access from the terminal: 5000/100 = 50.

・ When grouping terminals and selecting transfer terminals (this embodiment)
Number of terminal groups: 5000/10 = 500
Number of loopback accesses from terminal (transferr): 500
Number of application servers to support return access from the terminal (transfer role): 500/100 = 5.

  Therefore, in the communication system 1 of the present embodiment, the number of application servers can be reduced to 1/10 under the same conditions. In the conventional example, when the number of return accesses from the terminal is 30% (5000 × 0.3 = 1500), the number of application servers for supporting the return access from the terminal is 15 (1500/100). Become. Thus, even if the number of return accesses from the terminal is 30%, in the communication system 1 of the present embodiment, the number of application servers can be reduced to 1/3.

  In the communication system 1 of the present embodiment, the smart device group management module 26 (information terminal management unit) of the in-house AP server 20 has at least one of the operation status, continuous use time, network communication speed, and number of request requests of each terminal. Select the terminal that will be the forwarding role by referring to the two conditions. Therefore, the in-house AP server 20 can more reliably select a terminal suitable for the transfer role.

  In the communication system 1 of this embodiment, the smart device operation monitoring module 25 (information terminal operation monitoring unit) of the in-house AP server 20 transmits an operation response request silent push notification to each smart device, and whether or not response data has been received. Accordingly, the smart device group management module 26 is made to re-select the terminal serving as the transfer role. Therefore, the in-house AP server 20 accepts request requests from other terminals in the group by the terminal reselected as the transfer role even when the terminal selected as the transfer role cannot play the role of the transfer role. Can continue.

  Further, the smart device operation monitoring module 25 transmits an operation response request silent push notification to each smart device at a certain time interval, and a terminal serving as a transferer depending on whether or not response data is received within the time limit. Are selected again by the smart device group management module 26. Therefore, the in-house AP server 20 can reselect a terminal most suitable for the transfer role at that time in real time.

  In the communication system 1 according to the present embodiment, the request transfer module 33 (request request management unit) of the terminal serving as a transfer role collects request requests received from other terminals within a certain reception period in a batch to the in-house AP server 20. The transfer process is repeatedly executed every time the acceptance period ends. Therefore, even when request requests are asynchronously transmitted from other terminals, the transfer role terminal can transfer those request requests to the in-house AP server 20 more reliably.

  In the communication system 1 of the present embodiment, the request dispatch control module 34 of the smart device 30 directly accesses the in-house AP server 20 when the received new arrival information does not include the IP address and request reception port of the terminal serving as a transfer role. Issue a request. Therefore, the smart device 30 can more reliably transmit a request request even when a terminal serving as a transfer combination is not selected by the in-house AP server 20 or a terminal serving as a transfer combination is not in an operating state.

  The above-described embodiment is a preferred embodiment of the present invention. However, the scope of the present invention is not limited to the above-described embodiment, and various modifications are made without departing from the gist of the present invention. Implementation is also possible.

  In the present embodiment, an example in which newly arrived information data is sent to each terminal that has received a request request from the in-house AP server 20 has been described. However, the present invention is not limited to this. New arrival information data may be sent to a terminal serving as a transfer role, and the new arrival information data may be distributed from this terminal to other terminals in the same group. Note that the terminal to which the new arrival information data is sent is not limited to the transfer role terminal, and may be another terminal in the same group. In this case, the new arrival information data is distributed from the terminal that has received the new arrival information data to other terminals in the same group.

  In the present embodiment, the example in which the number of groups is determined based on the reception limit number of terminals serving as a transfer combination is described, but the present invention is not limited to this. A plurality of terminals may be grouped, and a terminal serving as a transfer role may be selected from terminals belonging to each group.
