Description

  The present invention relates to a notification method and a notification server for performing push notification to a mobile terminal.

  In recent years, mobile terminals such as smartphones and tablets are rapidly spreading. One of the features of such portable terminals is that OS such as iOS and Android is installed, and various information processing is possible by installing various applications (also called “applications”) on the functions provided by the OS. This is the point.

  Many application providers use push notifications to users for the purpose of improving the user's active rate.

  The push notification is performed using a remote notification service (APNs for iOS and GCM for Android) that can be used by each OS such as iOS and Android. In the remote notification service, a terminal that is a communication distribution destination and an identifier of an application installed in the terminal are managed, and a terminal identifier, an application identifier, and a message that is a notification content are transmitted from the provider of the application or an agency thereof. When received, a notification associated with the specified application is transmitted to the specified terminal.

  Notification formats include pop-up notifications called toast notifications, status notifications that display icons on the status bar, and the like.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

(Outline of the present invention)
The present invention does not perform push notification using a remote notification service that can be used by each OS of a mobile terminal as in the prior art, but as shown in FIG. 1, a notification server 110 that performs notification and a mobile that is a notification destination. A session is established with the terminal 120, and push notification information is transmitted to the mobile terminal 120 over the session.

  The notification server 110 includes a processing unit 111 such as a CPU, a storage unit 112, and a communication unit 113, and implements each function described below by executing a predetermined program. In the storage unit 112, a session established between the notification server 110 and the mobile terminal 120 is stored in association with the terminal identifier of the mobile terminal 120. An example of the terminal identifier is an IP address.

  The session can be compliant with the WebSocket standard. In order to perform push notification on a session, downstream communication from the notification server 110 to the portable terminal 120 is required. However, bidirectional communication, particularly full-duplex communication, is possible by using WebSocket. That is, the notification server 110 can distribute the push notification at an arbitrary timing without requiring a request from the mobile terminal 120.

  The notification part 112 for which the notification unit 112 performs push notification is stored in the storage unit 113 by storing a session table in which the association between the terminal identifier and the session is stored, and based on the terminal identifier input to the notification server 110 This can be done by specifying a session with reference to the session table. As the notification server 110, a batch process may be employed in which a distribution destination list including a plurality of distribution destinations is read and a push notification is sent to a specified session.

Each session can also be associated with an application identifier of an application installed on the mobile terminal 120. In this case, the communication unit 112 operates on the mobile terminal 120 on the session associated with the terminal identifier and the application identifier. Push notifications can be sent to the app. As an application identifier, for example, a reverse domain format (an identification method in which a package name is described in reverse domain notation to make it unique) can be cited. The notification destination can be specified by storing an application identifier in the session table and referring to the session table based on the terminal identifier and application identifier input to the notification server 110. The terminal identifier and the application identifier may be separate identifiers, or an identifier for identifying a set of terminals and applications may be used. The application can be, for example, an application for browsing a web page. Also, push notification information can be transmitted when the app is in the foreground state.

  The notification content of the push notification information to be transmitted can include at least one of characters, still images, moving images, and 3D content, and is displayed as a pop-up on the display screen of the mobile terminal 120. Specifically, when the mobile terminal 120 receives the push notification information, the mobile terminal 120 analyzes the content binary data included in the push notification information and the structured data constituting the web page such as HTML, CSS, and JS. Then, the push notification is displayed by assembling the content and the structured data on the display screen of the mobile terminal 120 and reconstructing the web page as a pop-up.

  The notification content may be created by an application provider and stored in the notification server 110 or a content management system (CMS) (not shown) to which the notification server 110 can be connected with an identifier.

  The push notification can be arranged on at least a part of the display screen of the mobile terminal 120, and the position, size, and shape can be adjusted according to the application.

  By doing in this way, the notification server 110 according to the present invention includes rich content such as a still image and a moving image at an arbitrary timing at an arbitrary terminal on condition that a session is established (described later). Arbitrary push notifications can be distributed with a high degree of freedom. Since the request from the portable terminal 120 can be made unnecessary, energy saving of the portable terminal 120 can be achieved. Further, when notification is made in response to a request from the portable terminal 120, the waiting time of the request is delayed, but according to the present invention, high-speed push notification can be realized.

(Push notification to web content)
In one embodiment of the present invention, a session is established in association with a web identifier that identifies web content such as a web page running on the mobile terminal 120, and on the mobile terminal 120 as shown in FIG. Push notification information is transmitted to the display screen of the application for browsing the web content that operates in.

  Examples of the web identifier include a URL of a website including web content. In this case, the notification server 110 first determines whether or not the URL associated with the session is viewed on the mobile terminal 120 by the module that establishes the full-duplex communication state with the notification server 110 that the website reads. If it is viewed, push notification information is sent. When the mobile terminal 120 receives the push notification information, the mobile terminal 120 analyzes the content binary data included in the push notification information and the structured data constituting the web page such as HTML, CSS, JS, and the mobile terminal 120. The push notification is displayed by assembling the contents and structured data on the display screen and reconstructing the web page as a pop-up.

By doing in this way, it becomes possible to perform push notification directly with respect to web contents, such as a web page.

  Note that when the application accesses a specific URL, the application identifier may be a web identifier.

  Further, when a push notification is given to a web page, it can be expressed by a different expression such as a banner format that is not a pop-up so as not to disturb the browsing of the site (content) that the user is browsing.

(Session management)
The session management according to the present invention includes several embodiments.

  Each session, when associated with an app, is established as the app starts and can be maintained while the app is running.

  The application may transmit the push notification information only in the foreground state while maintaining the session in either the foreground or background state.

  Further, when each session is associated with a URL, it can be discarded in response to a transition from the URL to another URL.

(How to establish a session)
The session establishment method according to the present invention can be broadly classified into at least two methods. The first method is a method of incorporating a session establishment module into an application operating on the mobile terminal 120. When the application is started on the mobile terminal 120, the module is executed to determine whether or not there is a session with the management server 110. If there is no session, a request for establishing a session from the mobile terminal 120 to the management server 110 In addition, a terminal identifier or a terminal identifier and an application identifier are transmitted to establish a session, and the newly established session is stored in the session table stored in the storage unit 113 of the management server 110. The management server 110 can determine the session based on the terminal identifier or the terminal identifier and the application identifier in order to establish a session for the received request, and return a response if the client is a target client, thereby establishing the session.

  In the second method, a session establishment module is stored in a web server accessed by an app for browsing web content that runs on the mobile terminal 120, and the web server is accessed from the mobile terminal 120. The module is transmitted to the mobile terminal 120 together with the web content. In the mobile terminal 120, the application executes the module and a session is established. The module may be stored in a web server, or may be stored on another server connectable from the web server. Maintenance such as module update becomes easy by putting it on another server.

  For example, when the operator designates the notification destination of the push notification from the management screen provided on the notification server 110, the notification server 110 determines whether or not there is a session with each notification destination (S301). When a session is established, a push notification is performed (S302). When a session is not established, a push notification (also referred to as “provisional push notification”) is performed using a remote notification service that can be used by each OS. ) Can be performed (S303). When the user taps or clicks the provisional push notification, the session can be established between the notification server 110 and the portable terminal 120 by the first or second method (S304).

  In the management server 110, for example, a flag is set in the session table to hold that the session corresponding to the terminal identifier and application identifier specified as the notification destination has not been established, and the flag is set. In response to the newly established session, the notification content is acquired from the CMS or the like in the same manner as during the establishment, and a push notification is given to the display screen of the application on the established session.

(User behavior history)
When a session is established between the notification server 110 and the mobile terminal 120, the notification server 110 can receive a user identifier such as a fingerprint from the mobile terminal 120 on the session. “Fingerprint” means at least one of browser type and version, OS type and version, screen resolution, usable font, plug-in, time zone, language and font setting, hardware configuration information, etc. This is a combination of multiple users that identifies users based on their differences.

  A function for acquiring a user identifier and sending it to the notification server 110 is given to the session establishment module or a separate history acquisition module. For example, the user accesses the first web page using the mobile terminal 120 From the first web page to the notification server 110 together with the user behavior history such as accessing a second web page different from the first web page, from the storage unit 112 of the notification server 110 or the communication server 110 You may store in the memory | storage part which can be accessed.

  When the notification server 110 receives the user identifier of the mobile terminal 120 at a predetermined timing after session establishment or at the time of session establishment, referring to the past user behavior history associated with the received user identifier, The notification content of the push notification to the mobile terminal 120 on the session can be determined. For example, referring to the user behavior history, for example, referring to information on the detailed page of the product, which is the first web page, the product interested in the first web page on the second web page It is possible to send a recommendation notification.

(Guidance and cooperation between web pages)
There is a huge number of web pages, and it would be highly desirable if there was a method for efficiently collecting access to newly created web pages. Instead of a push notification, a push notification associated with a new web page different from the existing web page is transmitted to a user who accesses the existing web page during a predetermined period. For example, it may be a push notification including the URL of a new web page in the notification content.

  This problem caused by the difficulty of providing an efficient lead to the newly created web page is that the top page of the website containing the newly created web page is the above existing web page, A particularly remarkable effect is obtained. Although the top page where articles headlines are often arranged has many visits, many users transition to a lower level web page in a short time, so many users are in a single push notification Although it is not easy to deliver to a user, many users can be captured by continuing the push notification for a predetermined period.

  In addition to the top page of the website including the new web page, it is also effective to use the top page of the website related to the new web page.

  In some applications, it is effective for the user to maintain a session while staying in the same domain. For this purpose, a keep_alive packet may be transmitted from the mobile terminal 120 to the server 110.

(Video wipe)
When the notification content of the push notification is a moving image, particularly a live game such as a sports game such as Olympics or high school baseball, a rocket launch, or a concert, in one embodiment of the present invention, display is performed as a wipe. In this specification, “wipe” is used as a term indicating a display area in which another image is displayed by providing a smaller area at the corner of the display area, or the display area.

  As a property of push notification, in some cases, it tends to be an obstacle to web content that a user tries to display. There is a high possibility that things that the distributor wants to display in preference to browsing web contents, such as advertisements, login password input requests to websites, password change guidance, and error display, will not be a problem. However, considering the fact that the actual start date / time is known but the exact start date / time is not always determined, it will be displayed on the user's web browser as a push notification. There is a risk that other work may become an obstacle.

  In one aspect of the present invention, a live video is used as a wipe at a predetermined time, such as 1 hour, 30 minutes, 10 minutes, 5 minutes, or 1 minute before the event start time or scheduled start time is approaching. Push notification of. The wipe position can be the corner of the display area of an application such as a web browser in the lower right, upper right, upper left, and lower left corners, and the wipe position can be fixed by scrolling the displayed page. Can remain. If the user desires, the wipe position can be changed by dragging the wipe.

  The event that is subject to video wipe may be an event related to the content of the web page or website displayed by the web browser, an event related to the user's interest determined from the user's past action history, etc. . Or you may deliver uniformly with respect to all or one part of the notification destination which the notification server 110 can notify.

  The video wipe display procedure is as follows. First, push notification information is transmitted to the mobile terminal 112. Next, the web browser of the mobile terminal 112 executes a script included in the push notification information and generates a display area for wiping in association with the web browser. Then, the live video is automatically reproduced in the wipe, or the reproduction is started in response to an input from the user to the wipe. Furthermore, the wipe may be enlarged or displayed in full screen in response to an input such as a tap or click from the user.

  The moving image displayed as the push notification may be a moving image that is not provided on the web page or website on which the display is performed. In this way, when displaying content that is irrelevant or low to the web content that the user is currently browsing, as a wipe as described above, the risk of hindering the web content that the user tries to display is greatly increased. Can be reduced.

(Effect measurement)
The remote notification service provided by each OS cannot confirm the effect of push notification, and it is difficult to make an effective push notification strategy. In the push notification according to the present invention using a session, information such as a user action after the push notification can be acquired on the management server 110 side. For example, by providing a questionnaire function for push notifications and counting responses from users, analysis for more effective push notifications becomes possible.

(Load reduction)
There may be restrictions on the number of portable terminals to which the notification server 110 can be connected or the number of WebSocket sessions that can be established simultaneously. Therefore, in one aspect of the present invention, a push notification is made to the second mobile terminal in which the WebSocket session is not established via the first mobile terminal in which the WebSocket session is established.

  First, the second mobile terminal makes a request for establishing a WebSocket session to the notification server 110. Next, when the notification server 110 determines that the number of established WebSocket sessions has reached a predetermined upper limit or the number of sessions, the notification server 110 returns a notification that the establishment is impossible to the second portable terminal. Here, the notification server 110 also returns the IP address of the first portable terminal that is establishing the WebSocket session. In this case, the second portable terminal establishes a WebRTC session compliant with the WebRTC standard with the first portable terminal using the WebSocket module or the separate WebRTC module. Then, when the first mobile terminal receives the push notification from the notification server 110, the first mobile terminal and the WebRTC session are currently connected to the second mobile terminal by the WebSocket module stored in the storage unit of the first mobile terminal or a separate WebRTC module. The push notification is transferred to the second portable terminal in response to the establishment of the.

  Thus, in one embodiment of the present invention, the load on the notification server 110 can be reduced.

(Other)
Rich push notifications using web expression technologies such as HTML, CSS, and JS can be freely expressed. As the expression mode, programs such as text, images, sounds, moving images, transparent animations, 3D contents, games, and the like can be used, and the shape of expression can also express a free shape that is not limited to a pop-up.

  In addition to push notifications that unilaterally express information as an additional function, push notifications that incorporate game characteristics are possible, for example, push notifications of programs such as Amida lotteries, and benefits are given when hit by user selection Push notification is possible.

  As an additional function, it is possible to perform push notification in which the content of the push notification cannot be confirmed unless the password previously determined by the user is input.

  As a web silent push function, it is possible to transmit a push notification that does not appear to the user's eyes from the notification server 110, rewrite a part of the displayed web page, update a part of the page, It is possible to change the advertising content at any timing.
