FIG. 4 is a sequence chart showing the push-type notification receiving method according to the first embodiment of the present invention.
(Step S1)
First, the information distribution device 20 transmits a push notification to the terminal device 100. At this time, the information distribution apparatus 20 transmits the push notification to be transmitted including the condition information related to the user notification.

(Step S2)
The terminal device 100 receives the push notification transmitted from the information distribution device 20. At this time, the terminal device 100 receives the push notification via either the wireless LAN 31 or the cellular NW 33 network. When receiving via the wireless LAN 31, the terminal device 100 communicates with the information distribution device 20 through the wireless LAN access unit 101. When receiving via the cellular NW 33, the terminal device 100 communicates with the information distribution device 20 through the cellular NW access unit 102. The push notification receiving unit 103 acquires a message ID and condition information from the acquired push notification. The push notification reception unit 103 generates a distribution information record based on the acquired message ID and condition information and the reception time of the push notification, and registers the distribution information record in the distribution information table. The push notification receiving unit 103 notifies the control unit 110 of the message ID of the acquired push notification.

(Step S3)
The control unit 110 acquires the message ID of the received push notification from the push notification receiving unit 103. The control unit 110 refers to the distribution information table and acquires condition information from the distribution information record corresponding to the acquired message ID. Based on the acquired condition information, the control unit 110 determines the timing of user notification regarding the push notification having the message ID. The control unit 110 instructs the user notification unit 107 to execute user notification at the determined timing. Hereinafter, a specific example of a method in which the control unit 110 controls the timing of user notification will be described.

[1. Control method based on date and time]
In the control method based on the date and time, the condition information included in the push notification is set with a date and time condition for performing user notification. In this case, the control unit 110 instructs the user notification unit 107 to execute user notification at the timing when the date and time indicated by the condition information has arrived.

[2. Control method based on position]
In the control method based on the position, a condition related to the position of the terminal device 100 is set in the condition information included in the push notification. In this case, the control unit 110 instructs the user notification unit 107 to execute user notification at the timing when the terminal device 100 is positioned at the position or range indicated by the condition information. In this case, the terminal device 100 includes a location information acquisition unit (not shown) that acquires location information of the device itself, and the control unit 110 determines the timing of user notification based on the location information acquired by the location information acquisition unit. Control. The position information acquisition unit may be configured using a GPS module that acquires position information from a GPS (Global Positioning System), or acquires position information such as an access point or a base station that connects the own apparatus to the network. May be configured.

[3. Control method based on the number of push notifications received]
In the control method based on the number of push notifications received, a condition regarding the number of push notifications received is set in the condition information included in the push notification. For example, in the condition information, the type of the received push notification and the threshold of the number of receptions related to the push notification of that type are set. In this case, the control unit 110 instructs the user notification unit 107 to execute the user notification at a timing when the cumulative number of push notifications received is equal to or less than a threshold value. For example, when the threshold value of the push notification related to the advertisement is set to 3 per day, the push notification related to the advertisement received in excess of 3 per day may be controlled not to perform the user notification.

[4. Control method based on the importance of push notifications]
In the control method based on the importance level of the push notification, the importance level of the push notification is set in the condition information included in the push notification. In this case, the control unit 110 instructs the user notification unit 107 to execute the user notification at a timing corresponding to the importance level. For example, a push notification with a low importance level may be controlled not to perform a user notification at night.

[5. Control method based on user notification interval]
In the control method based on the user notification interval, the condition information included in the push notification is set with a condition relating to the user notification interval. In this case, the control unit 110 instructs the user notification unit 107 to execute the user notification at a timing when the elapsed time from the previous user notification exceeds the time indicated by the condition information. For example, the user notification may be controlled to be at least 3 hours apart.

[6. Control method based on size of distribution information]
In the control method based on the size of distribution information (an example of attributes), the size of the distribution information is set in the condition information included in the push notification. In this case, the control unit 110 may control the user notification unit 107 to execute the user notification at a timing according to the size of the distribution information. For example, a push notification with a large distribution information size may be controlled so that a user notification is made at the timing when the distribution information is acquired.

  Note that the user notification timing control methods 1 to 6 described above may be used as individual control methods or may be used in combination. The above control method may be used for any timing control of the first user notification, the second user notification, and the third user notification. Furthermore, the user notification timing determined by the above-described control method may be controlled so as to be effective when the user is operating the terminal device 100. In this case, the fact that the user is operating the terminal device 100 may be determined based on, for example, whether or not the power of the display unit of the terminal device 100 is ON.

  When the control unit 110 determines that the condition indicated by the condition information is satisfied, the control unit 110 instructs the user notification unit 107 to execute the user notification. At this time, the control unit 110 outputs the message ID of the push notification that is the target of the user notification to the user notification unit 107. When it is determined that the condition indicated by the condition information is not satisfied, the control unit 110 determines again whether the condition is satisfied after waiting for a predetermined time.

(Step S4)
When receiving a user notification instruction from the control unit 110, the user notification unit 107 acquires a push notification corresponding to the notified message ID from the distribution information storage unit 105. The user notification unit 107 executes user notification of the acquired push notification. For example, when the user notification to be executed is the first user notification, the user notification unit 107 causes the display unit 108 to display a pop-up indicating that the push notification has been received. For example, when the user notification to be executed is the second user notification, the user notification unit 107 causes the display unit 108 to display a popup or the like that prompts the user to perform an operation for displaying the content of the push notification. For example, when the user notification to be executed is the third user notification, the user notification unit 107 notifies the application 106 of the message ID of the push notification.

(Step S5)
In addition, when the user performs an operation of displaying a push notification in response to the first user notification or the second user notification, the control unit 110 instructs the user notification unit 107 to execute the third user notification. The application 106 notifies the distribution information acquisition unit 104 of the message ID notified from the user notification unit 107. The distribution information acquisition unit 104 acquires a push notification corresponding to the message ID notified from the application 106 from the distribution information storage unit 105. The distribution information acquisition unit 104 communicates with the distribution information providing device 40 via the wireless LAN access unit 101 or the cellular NW access unit 102, and sends a transmission request for distribution information indicated by the push notification acquired from the distribution information storage unit 105. To the providing device 40.

(Step S6)
The distribution information providing unit 42 of the distribution information providing apparatus 40 receives the distribution information transmission request transmitted from the terminal apparatus 100. The distribution information providing unit 42 acquires the requested distribution information from the distribution information storage unit 43.
(Step S7)
The distribution information providing unit 42 transmits the acquired distribution information to the terminal device 100.

(Step S8)
The distribution information acquisition unit 104 of the terminal device 100 receives the distribution information transmitted from the distribution information providing device 40. The distribution information acquisition unit 104 stores the acquired distribution information in the distribution information storage unit 105 in association with the message ID.
(Step S9)
The application 106 acquires a push notification and distribution information corresponding to the message ID notified from the user notification unit 107 from the distribution information storage unit 105. The application 106 causes the display unit 108 to display the content of the push notification based on the acquired push notification and distribution information.

  According to the present embodiment, the terminal device 100 controls the timing of user notification based on the condition information set in the push notification by the information distribution device 20. By performing such timing control regarding the user notification, the timing at which the plurality of terminal devices 100 acquire the distribution information from the distribution information providing device 40 is distributed. Therefore, it is possible to acquire distribution information based on the push notification while suppressing a load applied to the distribution information providing apparatus 40.

  Note that the terminal device 100 may be configured to previously hold the condition information notified by the push notification in its own device. Furthermore, the terminal device 100 may be configured so that the user can change the condition indicated by the condition information. In this case, the terminal device 100 may be configured to selectively use the condition information notified by the push notification and the condition information held in the terminal device 100 based on a predetermined priority. Further, the terminal device 100 may be configured such that this priority can be set by the user.

[Second Embodiment]
The terminal device 100 according to the first embodiment controls the timing of user notification based on the condition information included in the push notification, thereby suppressing the load on the distribution information providing device 40 by acquiring the distribution information. On the other hand, the terminal device 100a of 2nd Embodiment controls the timing which acquires distribution information based on the state of an own apparatus.

  FIG. 5 is a block diagram showing a push type information distribution system according to the second embodiment of the present invention. The push type information distribution system according to the second embodiment is different from the push type information distribution system according to the first embodiment in that a terminal device 100a is provided instead of the terminal device 100. The terminal device 100 a is different from the terminal device 100 in that a distribution information acquisition unit 104 a is provided instead of the distribution information acquisition unit 104 and a control unit 110 a is provided instead of the control unit 110. The configuration other than the terminal device 100a in the push type information distribution system according to the second embodiment is the same as that of the push type information distribution system according to the first embodiment. In addition, functional units other than the distribution information acquisition unit 104a and the control unit 110a in the terminal device 100a are the same as those in the terminal device 100. Therefore, the same reference numerals as those in FIG. 1 are given to the same configurations, and the description in FIG. 5 is omitted.

  The distribution information acquisition unit 104a acquires distribution information from the distribution information providing device 40 at a timing notified from the control unit 110a. The distribution information acquisition unit 104a acquires the message ID of the push notification indicating the distribution information to be acquired from the control unit 110a as the timing notification. The distribution information acquisition unit 104 a acquires a push notification corresponding to the acquired message ID from the distribution information storage unit 105. The distribution information acquisition unit 104a acquires the distribution information indicated by the acquired push notification from the distribution information providing apparatus 40. The distribution information acquisition unit 104a associates the acquired distribution information with the push notification and stores them in the distribution information storage unit 105.

  The control unit 110a controls the timing at which the distribution information acquisition unit 104a acquires the distribution information based on the state of the own device. The control unit 110a determines the distribution information acquisition timing based on the state of the device itself, and outputs the push notification message ID that is the distribution information acquisition target to the distribution information acquisition unit 104a at the determined acquisition timing. By outputting this message ID, the control unit 110a notifies the distribution information acquisition unit 104a of the distribution information acquisition timing. A specific example of a method in which the control unit 110a controls the acquisition timing of distribution information based on the state of its own device is shown below.

[1. Control method based on identification information of own device]
In the control method based on the identification information of the own device, the control unit 110a determines the distribution information acquisition timing based on identification information such as a telephone number, SIM card unique information, and a MAC (Media Access Control) address. For example, when the telephone number is used as the identification information of the own device, the timing at which the last digit of the telephone number has elapsed from the timing when the push notification is received may be determined as the distribution information acquisition timing.

[2. Control method based on moving state]
When determining the acquisition timing of distribution information based on the movement state of the own device, the terminal device 100a includes a movement state acquisition unit (not shown) that acquires the movement state of the own device.

When determining the acquisition timing of distribution information based on the battery level of the own device, the control unit 110a includes a battery level acquisition unit (not shown) that acquires the battery level of the own device. The controller 110a determines the distribution information acquisition timing based on the remaining battery level acquired by the remaining battery level acquiring unit. For example, the control unit 110a may determine the timing at which the remaining battery level of the device is equal to or greater than a predetermined threshold as the distribution information acquisition timing.

[4. Control method based on display status]
In the control method based on the state of the display unit, the control unit 110 a determines the acquisition timing of distribution information based on the display state of the display unit 108. The display state of the display unit 108 is, for example, a state of screen brightness, power ON or OFF, and the like. In this case, for example, the control unit 110a may determine the timing when the screen power is ON as the distribution information acquisition timing.

  Note that the control methods 1 to 4 described above are examples of a control method based on the state of the terminal device 100a. The control unit 110a may be based on any state as long as the timing may be dispersed. You may determine the acquisition timing of delivery information. Further, the above-described delivery information acquisition timing control methods may be used as individual control methods or in combination.

  According to the present embodiment, the terminal device 100a determines the distribution information acquisition timing based on the state of the terminal device 100a. By controlling such timing regarding the acquisition of distribution information, the timing at which the plurality of terminal devices 100a acquire distribution information from the distribution information providing apparatus 40 is distributed. Therefore, it is possible to acquire distribution information based on the push notification while suppressing a load applied to the distribution information providing apparatus 40. In the second embodiment, since the acquisition timing of distribution information is determined based on the state of the terminal device 100a, the condition information is not set to push notification by the information distribution device 20 as in the first embodiment. Also, the distribution information acquisition timing can be distributed.

  In addition, the terminal devices 100 and 100a of the above-described embodiment are configured as terminal devices having both functions of user notification timing control based on condition information and distribution information acquisition timing control based on the state of the own device. May be.

  Further, the terminal device 100a may control the acquisition timing of the distribution information based on the condition information included in the push notification. Furthermore, the terminal device 100a may control the acquisition timing of the distribution information by combining the condition information and the state of the own device.

  For example, when information indicating a network used to acquire distribution information is set in the condition information, the control unit 110a controls the distribution information acquisition unit 104a to acquire distribution information using the network indicated by the condition information. May be. By performing such control, it is possible to distribute the load on the network by acquiring the distribution information.

  Contrary to the above, the terminal device 100a may be configured to control the timing of user notification based on the state of the terminal device 100a.

  As mentioned above, although embodiment of this invention was explained in full detail with reference to drawings, the specific structure is not restricted to this embodiment, The design change etc. of the range which does not deviate from the summary of this invention are included.
