Description

  The present invention relates to an inter-network data distribution system, an information communication terminal, and a content distribution server, and more particularly to a data exchange network used for content distribution.

Systems that electronically distribute periodicals such as newspapers, magazines, and weekly magazines via TCP / IP communication means have begun to be used. If the IP address on the receiving side is not known, push-type delivery is not possible, and it must be a pull type.
On the other hand, newspapers etc. issue tens of millions of copies. In the case of pull-type distribution, the distribution timing depends on the operation on the receiver side, so that it is necessary to prepare for the peak of the reception operation in consideration of the total capacity for the receiver. In other words, if the receiver receives the data evenly over time, the capacity will be low, but if it is received at any time, it will be necessary to anticipate a peak and prepare a server group with more capacity than necessary. I must.

On the other hand, a conventional technology of a pseudo push type in which a short mail is skipped and a content is a pull type is known. That is, when the receiving side is an information communication terminal using a mobile network, content distribution is scheduled by a Push distribution method (using an SMS function) depending on the mobile communication network.
The electronic newspaper distribution system disclosed in Patent Document 6 is a system using distribution reservation information registered in a mobile communication terminal, an external display device, a distribution server, and a distribution server. In this system, push distribution in which the distribution start timing is scheduled using the SMS function of the mobile communication network is realized.

Further, the following techniques are known for transmitting data via a data exchange network.
The technique disclosed in Patent Document 1 pushes presence and profile data to a mobile wireless computer device based on the position. In particular, claim 1 describes "automatically modify mobile computer device profile and presence information." And claim 4 states that "request transmission includes, but is not limited to, XMPP." .. done using one of the standard distance protocols. "

The technique shown in Patent Document 2 facilitates management for data distribution. In particular, claim 5 describes that “the distribution route attribute is checked and the optimum distribution route is automatically selected”.
The technique disclosed in Patent Document 3 discloses a message route selection system that dynamically selects an optimal message route. In particular, claim 1 describes that “a preferred route is dynamically selected from a plurality of available routes in order to transmit a message from a transmission source to a transmission destination”.

The technique shown in Patent Document 4 shortens the time required for a mobile user to acquire from a network. In particular, claim 1 describes that “the advertisement information is distributed in a push type without scheduling the distribution of all advertisement information and performing the operation of the advertisement recipient”.
The technique disclosed in Patent Document 5 distributes content adapted to the state of a receiving terminal. In particular, in claim 1, the information to be distributed is reconstructed based on the range of information to be distributed, and the reconstructed information is distributed to the mobile terminal that has transmitted the identifier indicating the communication connection state. And claim 3 states that “push-type information is distributed”.

Special table 2008-546266 gazette JP 2000-293458 A JP 2006-333486 A JP 2002-123741 A JP 2006-330933 A JP 2008-271455 A

  In the technique disclosed in Patent Document 6 described above, the distribution of content from the server depends on the communication function (SMS function) of the mobile communication device used for notification of the distribution timing. In other words, the SMS distribution function is used for the distribution timing, and the moving content distribution function is also used for content distribution. For this reason, there is a problem that other communication networks (for example, a fixed communication network) cannot be used. Further, it lacks the flexibility of selecting an optimal communication path when there are a plurality of communicable means. Further, by using a carrier-dependent service such as an SMS function, it is necessary to cooperate with a carrier in order to realize a distribution service, and lack of flexibility in providing an additional service when constructing an electronic book distribution business.

  In addition, the techniques shown in Patent Documents 1 to 5 do not distribute a certain content to a large number of users in an optimal distribution route in a short time.

In the present invention, content delivery is scheduled by a push notification method that does not depend on a carrier communication network (for example, using the XMPP protocol), and an optimum delivery route can be dynamically selected for a plurality of communication routes. .
As an example of the present invention, an information communication terminal and a content distribution server can be connected via a plurality of communication networks that can use a notification protocol for negotiation, and the content distribution server periodically transmits information to the information communication terminal. An inter-network data distribution system for distributing content, wherein the information communication terminal establishes a notification session by connecting from each of the plurality of communication networks using the notification protocol to the content distribution server, The content distribution server determines a distribution route and a distribution schedule using any of the plurality of communication networks, notifies the information communication terminal of the determined distribution route and distribution schedule, and the information communication terminal Wait until the scheduled delivery time according to the schedule, restart at the scheduled time, and Establishing a notification session with the delivery route, which is the notification with the Ntsu distribution server performs the distribution of content through the delivery path established between the information communication terminal and the content distribution server.

In the above configuration, the inter-network data distribution system periodically distributes content from the content distribution server to the information communication terminal. Here, the information communication terminal and the content distribution server can be connected via a plurality of communication networks that can use the notification protocol for negotiation.
First, a notification session is established by connecting from each of the plurality of communication networks using the notification protocol from the information communication terminal to the content distribution server. Thereby, the content distribution server can recognize a plurality of communication networks communicable with the information communication terminal, and can determine a distribution route and a distribution schedule using any one of them. Then, the information communication terminal is notified of the determined distribution route and distribution schedule.

  On the other hand, the information communication terminal waits until the scheduled delivery time according to the delivery schedule, restarts at the scheduled time, and establishes a notification session on the notified delivery route with the content delivery server. . Since this distribution route is notified in advance from the content distribution server side, even if there is a change in information on the mobile network or fixed network on the information communication terminal side, connection is possible from the information communication terminal side. Yes, a communication session can be established. Further, the delivery route itself can be selected within a range that can be recognized by the content delivery server, and usually the most efficient route can be selected. Accordingly, the content is distributed via the optimum distribution route established between the information communication terminal and the content distribution server at the timing scheduled in advance.

Here, the content distribution includes a distribution scheduler that determines the distribution route and distribution schedule, and a distribution server group that distributes the content, and a plurality of communication networks include a mobile network to which the information communication terminal subscribes, It is good also as a structure which consists of a fixed network of a non-mobile network.
In this case, a notification session is established from the information communication terminal to the content distribution server via the mobile network and the fixed network to notify the communication network.
Further, the distribution scheduler specifies the information communication terminal, specifies content to be distributed to the information communication terminal, specifies a communication band corresponding to a communication network with the information communication terminal, While determining a communication network as a distribution path based on the efficiency of the distribution server, determine a distribution server corresponding to the distribution path determined from the distribution server group, determine a distribution schedule, It is good also as a structure which notifies a delivery schedule to the said information communication terminal.

On the other hand, when the delivery schedule is notified, the information communication terminal may enter a sleep state, wait until the scheduled delivery time, and restart at the same time.
At this time, the information communication terminal may be configured to release the notification session via the mobile network and the fixed network before going into the sleep state.
Then, after restarting, the information communication terminal establishes a notification session with the distribution scheduler via the mobile network and the communication network of the distribution route, and the content distribution server uses the distribution scheduler to distribute the distribution The server notifies the server of distribution wait, the distribution server notifies the distribution scheduler of the start of distribution, the distribution scheduler notifies the information communication terminal of the start of distribution, and then the information communication terminal You may comprise so that the said content may be acquired via the communication network made into the said delivery route between the delivery servers.

Further, when the distribution is completed, the information communication terminal notifies the distribution scheduler of the content acquisition completion via the communication network of the distribution route, and the distribution scheduler notifies the distribution server of the completion of the distribution and the distribution. The scheduler may be configured to release the notification session via the communication network that is the distribution route with the information communication terminal.
The invention of the inter-network data distribution system configured as described above is not only regarded as the entire system, but is also established as an invention in each of the information communication terminal and the content distribution server that are its constituent elements.

  In this case, the information communication terminal establishes a notification session by connecting from each of the plurality of communication networks to the content distribution server using the notification protocol, and is determined by the content distribution server. Receives a delivery route and a delivery schedule using any of a plurality of communication networks, waits for the scheduled delivery time according to the delivery schedule, restarts at the scheduled time, and communicates with the content delivery server A notification session in the notified distribution route is established, and content is received through the distribution route established with the content distribution server.

In addition, when the content distribution server establishes a notification session by connecting from each of the plurality of communication networks to the content distribution server using the notification protocol from the information communication terminal, The distribution route and the distribution schedule using either of them are determined, the determined distribution route and the distribution schedule are notified to the information communication terminal, and the information communication terminal is restarted at the scheduled distribution time and notified. When the notification session is established through the distribution route, the content is distributed to the information communication terminal via the established distribution route.
Of course, it is also established as a system integrating the above, and the information communication terminal and the content distribution server can be connected via a plurality of communication networks that can use the notification protocol for negotiation. An inter-network data distribution system that periodically distributes content to the network, wherein the content distribution server includes a distribution scheduler that determines the distribution route and distribution schedule, and a distribution server group that distributes the content, The communication network is composed of a mobile network to which the information communication terminal subscribes and a non-mobile network fixed network, and the information communication terminal uses the notification protocol to the content distribution server via the mobile network. A notification session is established via the fixed network, and the distribution of the content distribution server is performed. The scheduler specifies the information communication terminal, specifies content to be distributed to the information communication terminal, specifies a communication band corresponding to a communication network with the information communication terminal, and based on the efficiency of the communication band While determining a communication network as a distribution route, a distribution server corresponding to the determined distribution route is determined from the distribution server group, a distribution schedule is determined, and the determined distribution route, distribution server, and distribution schedule are described above. When the information communication terminal is notified of the distribution schedule, after releasing the notification session via the mobile network and the fixed network before, it enters a sleep state and waits until the scheduled distribution time. Restart at the same time, establish a notification session to the distribution scheduler via the mobile network and the communication network of the distribution route, and at the content distribution server The distribution scheduler notifies the distribution server for distribution, the distribution server notifies the distribution scheduler of the start of distribution, and the distribution scheduler starts distribution to the information communication terminal. After that, the information communication terminal acquires the content via the communication network that is the distribution route with the distribution server, and the information communication terminal The content acquisition completion is notified via the communication network of the distribution route, the distribution scheduler notifies the distribution server of the completion of distribution, and the distribution scheduler is the communication network that is the distribution route with the information communication terminal. You may comprise so that a notification session of via may be open | released.

According to the present invention, content can be distributed via an optimal distribution route at a timing scheduled in advance. That is, content can be distributed using a planned and efficient distribution route, and a server group having a larger capacity than necessary is not necessary.
Further, according to the present invention, if the information communication terminal and the distribution server have TCP / IP communication means, reliable distribution can be performed regardless of whether the mobile network is a fixed network.
Furthermore, it is possible to select and distribute the most efficient communication network / path (for example, a cheaper and wider bandwidth fixed network than a mobile network) when performing distribution.

  Furthermore, the present invention does not require signaling means in a carrier network such as a mobile network / fixed network, so that service construction is facilitated.

It is a schematic block diagram of this network data delivery system. It is a figure which shows the procedure of the content delivery in this data distribution system between networks. It is a block diagram of this content delivery server.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
FIG. 1 is a schematic configuration diagram of the inter-network data distribution system.
In the figure, a browsing terminal 11 as an information communication terminal is a mobile terminal connected to and connected to a mobile network 12 and can also be connected to a fixed network 13 as a non-mobile network. Here, a feature of the mobile network 12 is that communication is secure. Mobile terminals are reliably managed by telecommunications companies. On the other hand, delivery of large-capacity content with a small bandwidth is not good.

On the other hand, the fixed network 13 is a so-called Internet network, and although the band size varies depending on the provider and communication line to be used, the band is much larger than the mobile network 12 if it is a broadband line. On the other hand, the communication path is open and the communication itself is non-secure. The connection between the browsing terminal 11 and the fixed network 13 is typically a wireless LAN, but may be a wired LAN or the like.
The content distribution server 14 includes a distribution scheduler 15 and a distribution server group 16, and is connected to the mobile network 12 and the fixed network 13, respectively. As will be described later, the distribution scheduler 15 determines a distribution route and a distribution schedule, and the distribution server group 16 has a plurality of distribution servers 17 (described later) corresponding to the communication band, and follows the distribution schedule. To distribute content in the corresponding band.

  In both the mobile network 12 and the fixed network 13, XMPP (XMPP: Extensible Messaging and Presence Protocol, standardized by IETFRFC3920,3921), which is a notification protocol for negotiation, can be used, and the browsing terminal 11 The content distribution server 14 implements communication negotiation using the XMPP protocol. In this embodiment, the XMPP protocol is used. However, the notification protocol is not particularly limited as long as it is a negotiation notification protocol. In addition, when distributing content, protocols such as HTTP and FTP can be used.

As described above, the inter-network data distribution system includes a browsing terminal 11 capable of TCP / IP communication, a plurality of content distribution paths (mobile network 12 and fixed network 13), a content including a distribution scheduler 15 and a distribution server group 16. The distribution server 14 is configured.
Next, FIG. 2 is a diagram showing a content distribution procedure in the inter-network data distribution system.
In the figure, the browsing terminal 11 is shown on the left side, and the distribution scheduler 15 and the distribution server group 16 are shown on the right side. On the left side, vertical lines representing communication on the mobile network 12 and communication on the fixed network 13 are shown. A horizontal line starting from or ending with a vertical line of each mobile network 12 and fixed network 13 represents communication using each communication network.

Hereinafter, content distribution will be described in time series with reference to FIG.
: Notification of distribution route When the browsing terminal 11 is activated and a program for periodic content distribution is activated, a notification protocol for negotiation is used between the browsing terminal 11 and the distribution scheduler 15 to Establish a communication session.
Browsing terminal 11 → distribution scheduler 15: notification session established via mobile network (12) Browsing terminal 11 → distribution scheduler 15: notification session established via fixed network (13)

  Here, prior to content distribution, all of the communication routes that can be communicated between the browsing terminal 11 and the content distribution server 14 are used by the negotiation notification protocol (XMPP), and the browsing terminal 11 and the content distribution server 14 are used. All communication sessions that can be established with are established. At this time, by using the negotiation notification protocol (XMPP), a session can be reliably established even if the viewing terminal 11 is at a fixed private address.

: Determination of distribution schedule When all communication sessions are established, the distribution scheduler 15 determines the distribution schedule. The browsing terminal 11 uses all possible distribution paths to notify the distribution scheduler 15, and the distribution scheduler 15 determines the optimal distribution path, distribution time, and distribution server, and notifies the browsing terminal 11.
Here, determination of this distribution schedule will be described.
FIG. 3 is a configuration diagram of the content distribution server.
In the figure, the content distribution server 14 includes a distribution schedule database 18 included in the distribution scheduler 15 and the individual distribution servers 17a to 17a in the distribution server group 16 in addition to the distribution scheduler 15 and the distribution server group 16 described above. 17d. Further, it is shown that an IP address database 18a, a user database 18b, and a schedule database 18c are included as individual databases constituting the distribution schedule database 18.

  The IP address database 18a is used for linking an IP address and a band and determining a server set to support the same band. That is, by referring to the IP address as an argument, the corresponding carrier, ISP, location, bandwidth, and server are read out. For example, if the IP address is 100 to 200, the bandwidth is 1 Mbps, and the server C (server 17c) corresponds to this bandwidth. If the IP address is 500 to 800, the bandwidth is 500 kbps, and it is understood that the server D (server 17d) corresponds to this bandwidth.

The user database 18b associates the content purchased by the user while associating the user with the terminal, and associates the terminal with its fixed IP address and mobile IP address. In addition, the previously used line used for the previous distribution is updated.
That is, when the user notifies the user ID via the communication session, the browsing terminal 11 that has notified the user ID is specified, so that the terminal ID is recorded (updated) in association with the terminal ID. The fixed IP address and the mobile IP address being acquired are acquired and recorded (updated). The last used line used for the previous distribution is updated with the used line determined by the distribution scheduler 15. However, the terminal ID may be recorded and updated upon receiving notification individually, or the terminal ID registered in advance may be used as it is. In particular, as long as the mobile network 12 is used, the terminal ID is managed by the communication company and does not need to be updated.

  For example, when the user notifies “12” as the user ID, it can be seen that the content ID is “101” with the user ID as an argument. Further, “22” of the communication terminal ID used in the notification is acquired and recorded, “101” is acquired as the fixed IP address of the used line, and “601” is set as the mobile IP address. Acquire and record each. In addition, referring to the database, it can be seen that content was distributed last time using a mobile network.

The schedule database 18c manages a distribution schedule in the content distribution server, and records a terminal ID, a user ID, a priority IP address, a line type, a server, and a content ID for content distribution at each time. ing.
For example, at “4:01”, the content is distributed to the terminal whose terminal ID is “22”. Further, the terminal is a user with a user ID of “12”, the IP address to be used (this is the priority IP address) and the line type “fixed” are recorded, and the server to be distributed is “C (server 17c) ”, and the content to be distributed has the content ID“ 101 ”.

The distribution scheduler 15 refers to, records, and updates these databases according to the following procedure to determine a distribution schedule.
When the distribution scheduler 15 receives a user notification from the browsing terminal 11 through the established notification session (i), the distribution scheduler 15 notifies the distribution schedule database 18 of the IP address used in the session with the user (ii). Here, the distribution scheduler 15 searches the user database 18b using the user ID of the user (iii) and records the used IP address. Since the established sessions are each of the mobile network 12 and the fixed network 13, a fixed IP address and a mobile IP address are acquired as IP addresses, and each is recorded.

Next, using these IP addresses, the IP address database 18a is referred to and a server to be used for distribution is determined (iv). If the IP address is known, the bandwidth can be understood by referring to the IP address database 18a. In general, it is best to use a distribution route with a large bandwidth. The bandwidth is determined by each of the fixed IP address and the mobile IP address, and the server with the larger bandwidth is determined as the distribution server (v).
When the distribution server is determined, the content ID specified by the user ID is referred from the user database 18b, and the distribution time and the distribution content are determined (iv). The time required for distribution to each user can be calculated by the content, distribution route, and distribution server, and is determined sequentially according to the capabilities of the content distribution server 14 after comprehensively considering these. I will do it. Then, the determined content is recorded in the schedule database 18c.

Thereafter, when the distribution scheduled time recorded in the schedule database 18c is notified to each of the distribution servers 17a to 17d (vii), each of the distribution servers 17a to 17d is designated as a distribution destination associated with the same time. The content specified by the content ID is distributed to the IP address (viii). In addition, since the priority IP address corresponds to the bandwidth and the distribution route at the same time, the line type is also handled by itself.
Next, this procedure will be described using a specific example.

Initially, the user ID notified from the viewing terminal 11 to the distribution scheduler 15 is “12”. From this user ID “12”, “101” is notified as the fixed IP address and “600” is notified as the mobile IP address, and these are recorded as the fixed IP address and the mobile IP address of the user database 18b.
Next, referring to the IP address database 18a using the fixed IP address “101” and the mobile IP address “600”, it can be seen that the bandwidth for the fixed IP address “101” is “1 Mbps”. It can be seen that the bandwidth for the IP address “600” is “500 Kbps”. Naturally, since the former has a wider band, in this case, it can be determined that the former should be used for distribution. Then, it is understood that the distribution server is “C”.

When the user database 18b is referred to with the user ID “12”, it is read that the content ID to be distributed is “101”.
At this time, it is assumed that a distribution schedule of “4:00” has been decided, and “4:01” can be set as the next distribution time. Then, as a distribution schedule of “4:01”, a terminal ID “22” corresponding to this user, a user ID “12”, a priority IP address “600” used for distribution, and a line type “fixed” ”,“ C ”as the distribution server to be used, and the content ID“ 101 ”to be distributed are recorded in the schedule database 18c as a distribution schedule. This record includes the distribution route as well as the distribution schedule.

: Notification of distribution schedule When the distribution schedule is determined as described above, the next notification is performed.

Distribution scheduler 15 → browsing terminal 11: Notification of distribution server, distribution time, and priority distribution route Note that the priority distribution route is a distribution route corresponding to the priority IP address. By receiving this notification, the viewing terminal 11 knows the delivery time, delivery route, and delivery server, knows the time to start the session again from the delivery time as described later, and should be established by content delivery. The distribution route is known, and the partner to start the session from the distribution server.
: Terminal standby

When the delivery schedule is determined, it waits until that time. There is no need to keep the power on during the standby time. For this reason, the browsing terminal 11 is put into the sleep state, but before that, the notification session established at the present time is released. That is,
Distribution scheduler 15 → browsing terminal 11: release notification session via mobile network Distribution scheduler 15 → browsing terminal 11: release notification session via fixed network. When the terminal goes to sleep, it is considered that the load on the system is lighter when the disconnection process is correctly performed from the terminal side than when the server detects the interruption of the session later.

: Terminal restart The browsing terminal 11 restarts in time for the delivery time notified earlier. This is performed actively by the browsing terminal 11 by a timer or the like.

: Preparation for distribution Since the restarted time is the time immediately before the scheduled distribution time, the browsing terminal 11 prepares the distribution scheduler 15 and the distribution server group 16 of the content distribution server 14 to start distribution. That is,
Browsing terminal 11 → distribution scheduler 15: Establish notification session via mobile network Browsing terminal 11 → distribution scheduler 15: Establish notification session via priority network Distribution scheduler 15 → distribution server 17: notification of waiting for distribution distribution server 17 → distribution scheduler 15: Notification of distribution start When the distribution time comes, the browsing terminal 11 connects to the distribution scheduler 15 again and waits for a notification of distribution start timing from the distribution server 17. The priority network is a communication network for distribution.

: Distribution When the distribution server 17 is ready, the distribution terminal 17 is notified of the distribution start via the distribution scheduler 15, and the browsing terminal 11 requests the distribution server 17 to start distribution and performs content distribution. .
That is,
Distribution scheduler 15 → browsing terminal 11: Notification of distribution start via priority network Browsing terminal 11 ← → distribution server 17: Content acquisition is performed via priority network / designated distribution server 17.
The delivery route specified here is an optimum one considering efficiency, and the content is delivered to the browsing terminal 11 via this optimum delivery route.
: Distribution end After the distribution ends, the browsing terminal 11 notifies the distribution server 17 of the distribution completion via the distribution scheduler 15. That is,

Browsing terminal 11 → distribution scheduler 15: Notification of content acquisition completion via priority network Distribution scheduler 15 → distribution server 17: Notification of distribution completion Distribution scheduler 15 → browsing terminal 11: Release notification session via priority network. Then, the distribution server 17 immediately starts distribution to the next browsing terminal 11 or the like.
In addition, in the case of femto base stations that are expected to expand in the future, even though the terminal uses radio waves for mobile networks, a large-capacity wired network passes through the tunnel from the base station to the mobile network. Configuration is also conceivable. In such a case, even if the interface is limited to one type for a mobile network, the relay route (or IP address assigned to the terminal) is used when using a femto base station or when using an existing base station. There are two paths. In this case, it seems that two logical interfaces exist simultaneously for one physical interface, and the method described in this patent can be used effectively.

When the information communication terminal is notified of the distribution schedule, after releasing the notification session via the mobile network and the fixed network before, it enters a sleep state, waits until the distribution scheduled time, restarts at the same time, Establish a notification session to the above distribution scheduler via the mobile network and the communication network of the distribution route,
In the content distribution server, the distribution scheduler notifies the distribution server for distribution of waiting for distribution, the distribution server notifies the distribution scheduler of the start of distribution, and the distribution scheduler notifies the information communication terminal. The information communication terminal then acquires the content via the communication network that is the distribution route with the distribution server,
When the distribution is completed, the information communication terminal notifies the distribution scheduler of the content acquisition completion via the communication network of the distribution route, the distribution scheduler notifies the distribution server of the completion of distribution, and the distribution scheduler An inter-network data distribution system that releases a notification session via a communication network, which is used as the distribution route with the information communication terminal. Inter-network data distribution in which an information communication terminal and a content distribution server can be connected via a plurality of communication networks that can use a notification protocol for negotiation, and content is periodically distributed from the content distribution server to the information communication terminal The same information communication terminal of the system,
The information communication terminal
Establishing a notification session by connecting to each of the plurality of communication networks using the notification protocol to the content distribution server,
Receiving a delivery route and a delivery schedule using any of the plurality of communication networks determined by the content delivery server;
Wait until the scheduled delivery time according to the above delivery schedule,
Reboot at the same scheduled time to establish a notification session on the notified distribution route with the content distribution server,
An information communication terminal, wherein content is received via a distribution route established with the content distribution server. Inter-network data distribution in which an information communication terminal and a content distribution server can be connected via a plurality of communication networks that can use a notification protocol for negotiation, and content is periodically distributed from the content distribution server to the information communication terminal The same content distribution server of the system,
The content distribution server
When a notification session is established from each of the plurality of communication networks using the notification protocol from the information communication terminal to the content distribution server,
Determining a distribution route and a distribution schedule using any of the plurality of communication networks, and notifying the information communication terminal of the determined distribution route and distribution schedule;
When the information communication terminal restarts at the scheduled delivery time and establishes a notification session in the notified delivery route,
A content distribution server for distributing content to the information communication terminal via the established distribution path
