  FIG. 11 is an example of an information distribution sequence in the first embodiment. What is indicated below (S) is a signal between the modules shown in the present embodiment.

For example, the information transmission / reception unit 20 receives context information such as position information from the position transmission device 6 and weather information from the Web server 3 that provides the weather information. (S1)
The received context information is transmitted to the context collection / processing / management unit 21 (S2) and stored and managed. At this time, the context information collection / processing / management unit 21 acquires the location information of the user related to the user via the information transmission / reception unit 20 and specifies a certain relationship (for example, a friend or a lover) with the user. It is also possible to calculate the distance between users and specify a user who is within a certain distance for a certain period as a companion.

  It is also possible to generate action history information indicating how much the user has visited an area within a certain period. The context information collection / processing / management unit 21 stores the user context information thus generated in the user context information (see FIG. 3).

When there is a change in the collected user context information, the context information collection / processing / management unit 21 notifies the central processing unit 23 of the change (S3). At this time, the user's context information itself may be notified together with the central processing unit 23, or the central processing unit 23 may separately collect the context collection / processing / management unit 21 (S4). (S5)
The central processing unit 23 confirms the user subscription service (see FIG. 4) managed by the user information management unit 22 (S6), and the service ID that can be received by the user and the user profile (see FIG. 5). The managed user profile information (see FIG. 5) is acquired (S7). For example, the service ID may be given in units such as XX magazines or XX stock information magazines, or may be given in units such as information from friends.

  Next, information distribution from the information distribution server 2 will be described.

  The central processing unit 23 confirms the content distribution conditions (see FIG. 6) of the content information management unit 24 based on the user ID, service ID, user profile information, and user status (S8), and can be received by the user. Content that matches the user's situation is extracted (S9).

  Next, the content ID being distributed to the user terminal is acquired from the content being distributed by the user managed by the display data management unit 26 (see FIG. 7) (S10), and is not currently distributed among the extracted content. Content is extracted (S11).

  The central processing unit 23 confirms the notification destination information such as the IP address and mail address of the notification destination user from the user profile information of the user information management unit 22 to the user profile referred to in FIG. 5 (S20), and acquires (S21). ) This process may be performed simultaneously with the process of (S6).

  The central processing unit 23 requests the information transmission / reception unit 20 to distribute the information acquired by the content information management unit 24 to the notification destination information acquired by the user information management unit 22 (S22).

  The information transmitting / receiving unit 20 notifies the content information to the user terminal 1 using a communication protocol such as CORBA, HTTP, Socket, smtp, TCP / IP, for example (S24). (S23) and (S25) are response signals from the user terminal 1.

After the notification, the central processing unit 23 records the correspondence between the user ID and the content ID distributed to the user-distributed content in the display data management unit 26 in FIG. (S26)

  FIG. 12 shows a sequence between internal modules for displaying information in the user terminal 1. The content received by the information transmitting / receiving unit 10 is notified to the display data managing unit 14 (S30). The display data management unit 14 stores the received content and instructs the information display unit 11 to display the content (S31). In the display of the content, the received information may be displayed on the screen as it is as shown in FIG. 13 (a), or the information itself is displayed instead of displaying the information itself as shown in FIG. 13 (b). An icon or the like may be displayed.

  Note that the display data management unit can omit the saving process when the same content has already been received and saved when the received content is saved.

  Next, information deletion from the information distribution server 2 will be described.

  11 indicates a procedure for deleting the content being displayed on the user terminal 1. The central processing unit 23 confirms the content being distributed to the user from the content being distributed by the user (see FIG. 7) managed by the display data management unit 26 (S12), and acquires the content (S13). Among these contents, a request is made for a content ID that matches the user's context status and the condition of the content deletion condition (see FIG. 10) managed by the content information management unit 24 (S14), and is acquired (S15). .

  Thereafter, the central processing unit 23 inquires and obtains information about the notification destination such as the IP address and mail address of the deletion notification user from the user information management unit 22 in the same manner as in the information distribution process (S20). Further, this process may be performed simultaneously with the process of (S6).

  The central processing unit 23 requests the information transmitting / receiving unit 20 to transmit the information deletion request acquired by the content information management unit 24 to the information notification destination acquired by the user information management unit 22 (S22).

  After the notification, the central processing unit 23 deletes the correspondence data between the user ID and the content ID requested to be deleted from the user-distributed content (see FIG. 7) in the display data management unit 26 (S26).

  Next, information deletion at the user terminal 1 will be described.

  The framed portion of the dotted line in FIG. 12 shows the procedure for erasing the displayed content on the user terminal 1. The information deletion request received by the information transmitting / receiving unit 10 is notified to the display data management unit 14 (S32). The display data management unit 25 deletes the managed content information or sets a non-display flag with the content remaining, and requests the information display unit 11 to hide the content (S33). If the user is browsing the content, it may be deleted after browsing.

  Next, information monitoring will be described.

  FIG. 14 is a sequence for notifying the information delivery server 2 of the presence / absence of content confirmation by the user.

  The content confirmation monitoring unit 13 in the portable information terminal monitors whether the user has confirmed the received content information. For example, when the content itself is displayed as shown in FIG. 13 (a) and the user terminal is a foldable portable terminal, it is understood that the user has confirmed by opening the terminal.

  In addition, when an icon or the like indicating that there is information is displayed as shown in FIG. 13B, it is understood that the user has confirmed the information by pressing the icon and displaying detailed content. When the content confirmation monitoring unit 13 grasps the content confirmation of the user (S34), the information transmission / reception unit 20 of the information distribution server 2 is notified of the presence / absence of content confirmation via the information transmission / reception unit 10 (S35).

  The information transmitting / receiving unit 20 of the information distribution server 2 notifies the central processing unit 23 of the received content confirmation presence / absence information (S36), and the central processing unit 23 refers to the user confirmation log of the confirmation log management unit 25 shown in FIG. A value is set to (S37).

  Although the above shows a method of notifying the content distribution history of the user to the information distribution server 2 every time the content confirmation monitoring unit 13 grasps, the content confirmation monitoring unit 13 accumulates the content confirmation history for a certain period separately. However, the information may be transmitted to the information distribution server 2 collectively when the content is received from the information distribution server.

  The content confirmation history accumulated in the confirmation log management unit 25 is distributed once in the process of selecting the content to be distributed to the user terminal 1 by the central processing unit 23, for example, within the solid line frame in FIG. Is a process referred to in (S16) and (S17).

  With this process, it is possible to confirm whether or not the information recipient has browsed the information, and the unread information can be displayed again according to the situation. This realizes provision of fresh information for the information receiver.

  Next, the reminder function will be described.

  The user can request (reminder designation) to select the content displayed on the user terminal 1 and display it again later or when the same situation occurs next time.

  FIG. 15 is a sequence diagram for notifying the information delivery server 2 of the content designated by the user as a reminder.

  The reminder request receiving unit 12 specifies a content ID designated by the user as a reminder using an input / output device of the user terminal 1 such as a button, a tap, or a mouse.

  The request for redisplaying the content designated by the reminder is transmitted to the information transmitting / receiving unit 20 of the information distribution server 2 via the information transmitting / receiving unit 10 of the user terminal 1 (S38) (S39). The content re-display request received by the information transmitting / receiving unit 20 is stored together with the user ID and the content ID requested for the reminder in the reminder content in FIG. 9 of the content re-display request information management unit 200 via the central processing unit 23 (S40). (S41).

  In addition, although the above showed the method of notifying the content redisplay request to the information distribution server 2 every time the reminder request receiving unit 12 grasps, the reminder request receiving unit 12 stores the content redisplay request separately for a certain period. Then, the content may be sent to the information distribution server 2 collectively when the content is received from the information distribution server 2.

  The data of the reminder content (see FIG. 9) may be deleted when the user confirms the content again, or may not be deleted unless the user explicitly specifies the cancellation of the redisplay request.

  The content redisplay request stored in the content redisplay request information management unit 27 is a process in which the central processing unit 23 selects content to be distributed to the user terminal 1 as in the double line framework of FIG. This is a process referred to in (S18) and (S19), which can be used for processes such as preferentially selecting information that has been distributed once but requested to be displayed again by the user.

At this time, the context information collection / processing / management unit 30 acquires the location information of the user having a relationship with the user via the information transmitting / receiving unit 10 and specifies a certain relationship (for example, a friend or a lover) with the user. It is also possible to calculate the distance between users and specify a user who is within a certain distance for a certain period as a companion.

  It is also possible to generate action history information indicating how much the user has visited an area within a certain period. The context information collection / processing / management unit 30 stores the user context information thus generated in the user context information (see FIG. 3).

  When there is a change in the collected user context information, the context information collection / processing / management unit 30 notifies the central processing unit 31 of the change (S52). At this time, the user's context information itself may be notified together with the central processing unit, or the central processing unit may separately inquire the context collection / processing / management unit (S53) and collect (S54).

  Next, information acquisition will be described.

  The central processing unit 31 transmits the received context information together with the user profile such as the user ID / password to the information distribution server 2 via the information transmitting / receiving unit 10 (S55).

  The information transmitting / receiving unit 20 transfers the received information to the central processing unit 23. (S56) The central processing unit 23 performs user authentication with reference to the user profile (see FIG. 5) managed by the user information management unit 22, and if the authentication is successful, the user subscription service (see FIG. 4). ) Is confirmed (S57), and a service ID that can be received by the user is determined (S58).

  The central processing unit 23 confirms the content distribution conditions (see FIG. 6) of the content information management unit 24 based on the user ID, service ID, user profile information, and user context information (S59), and is received by the user. A content ID that is a possible service and matches the user's context is extracted. Further, the deletion condition for the content ID is acquired from the content deletion condition (see FIG. 10) (S60).

  The central processing unit 23 confirms the user profile information of the user information management unit 22 (S61) and acquires (S62) the notification destination information such as the IP address and mail address of the notification destination user. This process may be performed simultaneously with the process of (S57).

  The central processing unit 23 requests the information transmission / reception unit 20 to distribute the content acquired in the above step and the deletion condition for the content (see FIG. 10) to the content information notification destination acquired by the user information management unit 22 (S63). ) The information transmitter / receiver 20 notifies the content information to the user terminal 1 using a communication protocol such as CORBA, HTTP, Socket, smtp, TCP / IP, for example (S64).

  The information transmitting / receiving unit 10 notifies the central processing unit 31 of the received information (S65). The central processing unit 31 notifies the display data management unit 14 of the received content (S66). The display data management unit 14 stores the received content and instructs the information display unit 11 to display the content (S67). The central processing unit 31 registers the deletion condition table received at the same time in the content information management unit 34.

  When the central processing unit 31 transmits the context information to the information distribution server 2 (S55), the content ID list managed by the display data management unit 14 is also notified to the information distribution server 2, It is also possible to avoid redundant acquisition of content held in the user terminal.

  Next, information deletion will be described.

  FIG. 18 is a sequence diagram of content deletion based on presence / absence of content confirmation by the user.

  The central processing unit 31 matches the context information received from the context collection / processing / management unit 30 (S52) and the content deletion condition (see FIG. 10) managed by the content information management unit 34. The presence / absence of content information is confirmed (S70) and acquired (S71). If there is a matching content, the content stored in the display data management unit 14 is deleted (S72). Also, the content displayed on the information display unit 11 is not displayed (S73).

  Instead of deleting the content stored in the display data management unit, a non-display flag can be set with the content remaining.

  Next, information monitoring will be described.

  FIG. 19 is a sequence diagram for notifying whether the user has confirmed the content.

  The content confirmation monitoring unit 13 of the user terminal 1 monitors whether the user has confirmed the received content information, and notifies the confirmation log management unit 32 of the result via the central processing unit 31 (S75).

  The central processing unit 31 can be used for processing such as preferentially selecting information that has been displayed once from the content received from the information distribution server 2 but has not been confirmed by the user.

  With this process, it is possible to confirm whether or not the information recipient has browsed the information, and the unread information can be displayed again according to the situation. This realizes provision of fresh information for the information receiver.

  Next, the reminder function will be described.

  The user can request (reminder designation) to select the content displayed on the user terminal 1 and display it again later or when the same situation occurs next time.

  The reminder request receiving unit 12 specifies a content ID designated by the user as a reminder using an input / output device of the user terminal 1 such as a button, a tap, or a mouse.

  The request for redisplaying the content designated by the reminder is stored in the reminder content (see FIG. 9) of the content redisplay request information management unit 33 together with the user ID and the content ID for which the reminder is requested.

  The data of the reminder content (see FIG. 9) may be deleted when the user confirms the content again, or may not be deleted unless the user intentionally designates cancellation of the redisplay request.

  The content redisplay request stored in the content redisplay request information management unit 33 is displayed once, for example, among the content received by the central processing unit 31 from the information distribution server 2, but the user requests to display again. It can be used for processing such as selecting information with priority.

  If the content of the embodiment described above is advertisement information including an electronic coupon, the electronic coupon is distributed to users in accordance with conditions such as a place, time, and companion specified by an advertiser (for example, a restaurant). can do. For example, “only a couple in the immediate vicinity of a store will be able to distribute a discount coupon for 30 minutes from now”.

  Also, by collecting electronic coupons that match the user's situation in the user's portable information terminal, the user can easily obtain an electronic coupon of “only now and here”.
