Description

  The present invention relates to a content distribution method and a user terminal for distributing content to a user terminal, and more particularly, to a content distribution method and a user terminal for collectively transmitting a plurality of contents to a user terminal.

  In recent years, mobile phones are used not only for telephone calls but also for sending and receiving e-mails and for WEB browsing. The mobile phone can download contents such as music, games, electronic comics, and moving images. The mobile phone functions as a player that plays downloaded music, functions as a game machine that executes downloaded games, functions as an electronic book that displays downloaded electronic comics, and plays a downloaded video Function as.

  Techniques related to the present invention include the following.

  For example, the content distribution apparatus automatically synthesizes a plurality of contents with a layout set in advance in the layout specification data to generate one composite data file, and should be arranged for each content data on the content distribution side There is a technique in which the position need not be specified, and the labor of creating the distribution data can be saved (for example, refer to paragraph 42 of Patent Document 1).

  Further, there is a technique in which a user terminal device receives a metafile, receives a plurality of contents described in the metafile from different content distribution server devices, and continuously plays back the contents (for example, (See Patent Document 2, paragraphs 35 to 39).

  In addition, there is a technology in which a user of a mobile device can zap a plurality of channels by pressing the left and right keys when the server pushes content contracted to the mobile device (for example, non-transmission). (See Patent Document 1).

Furthermore, there is a technique for regularly distributing program data registered by a user to a mobile phone from midnight to early morning on a fixed day of the week (see, for example, Non-Patent Document 2).

  The best mode for carrying out the present invention will be described below in detail with reference to the drawings.

  FIG. 1 is a diagram illustrating a configuration of a communication system for performing a content distribution method according to an embodiment of the present invention.

  Referring to FIG. 1, in this communication system, a RAN (Radio Access Network) 103, a user terminal (for example, a mobile phone, a PDA, a personal computer) 101 and a casting server 102, SGSN (Serving GPRS Support Node) 104, GGSN (Gateway GPRS Support Node) 105, and communication path via WPG (WAP Gateway) 106; RAN 103, MSC (Mobile Service Switching Center) 107, SMS-C (Short Message Service Center) 108 and PPG (Push Proxy Gateway) ) 109 communication path Is established.

  SGSN 104 and MSC 107 are connected to an HLR (Home Location Register) 110.

  In addition, the casting server 102 includes a Subs. A DB (Subscribers Database) 111 is connected. Further, the casting server 102 includes CP (Contents Provider) -1, CP-2, CP-3, CP-4,... (Reference numerals 112-1, 112-2, 112-3, 112-4, ...) are connected.

  CP-1, CP-2, CP-3, CP-4,... (Reference numerals 112-1, 112-2, 112-3, 112-4,...) It is held or generated and supplied to the casting server 102.

  Subs. The DB 111 stores, for each contractor, information as to whether or not a contract for receiving a content distribution service has been concluded, and if so, identification information of a channel that is desired to be distributed. ing.

  The casting server 102 is subs. Based on the information stored in the DB 111, CP-1, CP-2, CP-3, CP-4,... (Reference numerals 112-1, 112-2, 112-3, 112-4,... The contents and index parts of each channel supplied from () are combined to generate multi-part content, which is distributed to the user terminal 101.

  FIG. 2 is a diagram illustrating a configuration of an application and the like of the user terminal 101.

  Referring to FIG. 2, a casting application 122, a casting data folder 123, a browser 124, a media player 125, and a mailer 126 are present in the upper layer of the WAP 2.0 communication unit 121.

  The casting application 122 communicates with the casting server 102 to download and manage content. The casting data folder 123 stores a plurality of multi-part contents. A plurality of multi-part content includes a back number.

  FIG. 3 is a diagram illustrating an example of content for each channel and each day of the week.

  Referring to FIG. 3, there are channels A to U as channels. Channels A to I are small content channels, and the content capacity is limited to 100 kilobytes or less. Channels Z to U are large-capacity content channels, and the content capacity is limited to 500 kilobytes or less.

  For example, some channels distribute content on all days of the week, such as channels A to E, while other channels distribute content only on some days of the week, such as other channels.

  When the user has concluded a contract for receiving content distribution, the user selects one or more channels to be distributed. In the example of FIG. 3, the user has selected channels C, F, G, H, Z, and Y.

  FIG. 4 is a diagram for explaining a method for generating multi-part content.

  As an example, the channels selected by the user are channels C, F, G, H, Z, and Y. The casting server 102 collects the content of these channels and generates one content in a multi-part format. Further, the casting server 102 generates an index page including hyperlinks to other parts, and adds the index page as one part to the multi-part format content.

  Note that a part of a channel having no content to be distributed on the day of the week may be omitted.

  The casting server 102 delivers one multi-part type content thus obtained to the user terminal every day.

  Distribution is performed at a specific time. The specific time zone may be, for example, a time zone in which the traffic volume in the mobile telephone network is a predetermined value or less. Alternatively, the specific time zone may be a late night or early morning time zone. As a late night or early morning time zone, for example, a time zone that starts at any time between 9 pm and 4 am and continues for a predetermined period of 10 hours or less and ends by 7 am at the latest May be selected. By selecting a specific time zone in this way, it is possible to avoid pressing down the line capacity for other communications (communication for calls, mail, WEB browsing, etc.).

  FIG. 5 is a sequence diagram showing a procedure for content distribution.

Referring to FIG. 5, the casting server 102 uses SMS (Short Message Service),
Push (SL: Application ID = x-wap-application: casting.ua
(href = http://www.vodafone.com/cast/20041015.html)
Is transmitted to the user terminal 101 via the PPG 109. Here, SL is an abbreviation for service loading, and x-wap-application: casting.ua is the name of the casting application 122 to be activated by this message, http: // www. vodafone.com/cast/20041015.html is a URL (Uniform Resource Locator) which is the location information of the multi-part format content to be distributed today. The server having this URL is the casting server 102. However, another server may be used as long as the content to be distributed is stored.

  Next, the casting application 122 is started, and the casting application 122 establishes a TCP session with the casting server 102, and http://www.vodafone.com is transmitted to the casting server 102. Request transmission of one multi-part format content indicated by /cast/20041015.html. In response to this request, the casting server 102 transmits one multi-part format content indicated by http://www.vodafone.com/cast/20041015.html to the casting application 122.

  By combining the contents of multiple channels into one multi-part content, if the communication of the sequence shown in FIG. The content of the selected channel can be distributed to the user terminal. On the other hand, if the contents are distributed for each channel without collecting the contents of a plurality of channels, communication of the sequence shown in FIG. 5 or a sequence similar to this is performed for the selected number of channels per day. Need arises. Therefore, the former which is this embodiment can improve the efficiency of communication compared with the latter.

  FIG. 6 is a diagram for explaining a content management method by the casting application 122.

  Referring to FIG. 6, the casting application 122 accumulates multi-part format contents in a casting data folder 123 in a FIFO (First-In First-Out) format. To do. If the content of the latest multi-part format is added to the casting data folder 123 by capacity calculation, and it is determined that the casting data folder 123 overflows, the oldest multi-part format stored date and time Delete the contents of. FIG. 6 shows that when the content of the multi-part format for October 15, 2004 is added to the casting data folder 123, the casting data folder 123 overflows, and for October 8, 2004. It shows an example of deleting the multi-part format content.

  If the overflow is not solved even if the oldest stored multi-part content is deleted, the next old multi-part content is deleted.

  As described with reference to FIG. 3, an upper limit is set for the content capacity of each channel. Therefore, considering this, it is possible to limit the number of channels that the user can select so that the total capacity does not exceed a predetermined capacity. Therefore, after setting such a limit, the capacity of the casting data folder 123 is set to a capacity obtained by multiplying the predetermined capacity by the guaranteed accumulation days, so that the user can accumulate the back number. The number of days can be guaranteed.

  If the capacity of the casting data folder 123 is surplus, the back number that has passed the guaranteed accumulation days may be left in the casting data folder 123.

  FIG. 7 is a diagram for explaining a method by which the casting application 122 selects content and passes it to the browser 124.

  Referring to FIG. 7, the casting application 122 reads the latest content or one of one or more back numbers selected by the user from the casting data folder 123 as one multi-part content. This is passed to the browser 124. When passing to the browser 124, the multi-part content is stored as a single file in a buffer (not shown).

  In order for the browser 124 to read the index page, the part to be read first by the browser 124 is designated in the header part of the multi-part format content.

  FIG. 8 is a diagram showing an example of specific description contents of multi-part format content.

  In the first line, “boundary” is designated as a character string that becomes a boundary between parts. Then, “—boundary” is described at the part boundary. The index page describes hyperlinks to the contents of each channel (for example, <a href=“ch-c.html” horoscope</a>).

  On the third line, “index.htm” is designated as the name of the part that the browser should read first. In the seventh line included in the index page, “index.htm” is described as the name of the part of the index page. As described above, using these, the browser first reads the index page.

  FIG. 9 shows the transition of the screen when the user selects the content of the horoscope channel from the latest multi-part format content.

  The casting application 122 displays a casting menu 131. When the user selects the latest content 131 a, the casting application 122 reads the latest content from the casting data folder 123 as one multi-part format content and passes it to the browser 124. When passing to the browser 124, the multi-part content is stored as a single file in a buffer (not shown). Then, the browser 124 displays the index page 132. In order for the browser 124 to read the index page, the part to be read first by the browser 124 is designated in the header part of the multi-part format content. When the user selects the horoscope item 132a, the content of the horoscope channel in the latest content is read based on the hyperlink information set in this item, and the horoscope page is based on this. 133 is displayed. In the horoscope page, if an item associated with hyperlink information to a part included in multi-part content is selected, it jumps to that part and goes to the WWW server connected to the Internet. If an item associated with information for hyperlinking to a stored page is selected, the page jumps to that page.

  FIG. 10 shows the transition of the screen when the user selects the content of the horoscope channel from the multi-part format content that is the back number.

  The casting application 122 displays a casting menu 131. When the user selects the back number 131b, the casting application 122 displays a back number menu 134. When the user selects the item 134a of October 10, 2004, the casting application 122 reads the content of October 10, 2004 from the casting data folder 123 as one multi-part format content. Is passed to the browser 124. When passing to the browser 124, the multi-part content is stored as a single file in a buffer (not shown). Then, the browser 124 displays the index page 135. In order for the browser 124 to read the index page, the part to be read first by the browser 124 is designated in the header part of the multi-part format content. When the user selects the horoscope item 135a, based on the hyperlink information set in this item, the content of the horoscope channel of the content of October 10, 2004 is read out, and this is used as the basis. A page (not shown) similar to the horoscope page 133 is displayed.

  A series of communication sequences shown in FIG. 5 is performed in a specific time period as described above, and if the communication is successful, the browser can display all the parts of the latest content. However, for example, due to a bad radio wave situation, the communication of the series of sequences shown in FIG. 5 does not necessarily end successfully in a specific time zone. In the case of failure, for example, the user can recognize the failure because the content of a certain channel cannot be displayed. In order to cope with such a case, the latest content can be downloaded to the user terminal by a user operation even after a specific time period has elapsed. You may or may not charge for this download. If it is assumed that the user is charged for such a download outside of a specific time, the latest content can be downloaded to the user terminal by user operation, not automatically, When the user terminal displays a screen that allows the user to know that the user is charged when performing the operation, a situation in which the user is inadvertently charged for the download can be avoided.

  FIG. 11 shows a screen for starting to download the latest content to the user terminal by the user's operation. When the user selects the update item 141a on the screen 141 for displaying channel selection or the like, a series of sequence communication as shown in FIG. 12 is started. In the example of FIG. 11, charging for this communication is displayed. The user can know that the user is charged for re-downloading by viewing this screen.

The sequence shown in FIG. 12 uses SMS from the casting server 102 to the user terminal 101 shown in FIG.
Push (SL: Application ID = x-wap-application: casting.ua
(href = http://www.vodafone.com/cast/20041015.html)
This message is based on the premise that the message has been successfully transmitted. Compared with the sequence shown in FIG. 5, only the message transmission is deleted. If the transmission of this message has not ended, the user terminal 101 performs communication with the casting server 102 to request the casting server 102 to transmit this message. The communication shown in the sequence shown is performed again.

FIG. 13 shows that the user terminal 101
Push (SL: Application ID = x-wap-application: casting.ua
(href = http://www.vodafone.com/cast/20041015.html)
When the user terminal 101 has continued to communicate using the packet bearer from the past when trying to request the casting server 102 to transmit content immediately after receiving the message The operation is shown. Although FIG. 13 shows communication between the browser 124 and the WWW server 113 as this communication, other communication may be used. Whether or not communication using a packet bearer is being performed can be determined by checking whether or not a PDP-Context (Packet Data Protocol-Context) is active.

  In such a case, the casting application 122 starts a timer that counts down a predetermined time, and every time the timer value becomes zero, it determines whether other communication using the packet bearer is still continuing. to decide. If it is still continued, the timer is started again, and the same determination is made again after a predetermined time. When it is determined that the continuation has ended, as shown in FIG. 13, establishment of a TCP session, a request for transmission of multi-part format content, and reception of multi-part format content are started. As described above, after receiving the multi-part format content, the casting application 122 stores the content in the casting data folder 123.

  If other communication using a packet bearer has been continuously performed from the past, if communication related to multi-part content is started, the latter communication will interrupt the former communication, and the former communication will be interrupted. Communication speed will drop. In the present embodiment, as described with reference to FIG. 13, when other communication using the packet bearer has been continuously performed from the past, communication regarding multi-part format content is not started. Therefore, the communication speed of the former will not drop. On the other hand, even if the start of the latter communication is delayed, it is estimated that there are few users who want to see the latest content at a predetermined time such as midnight or early morning, and the user enjoys other communications at that time. There is little reduction in user satisfaction with the service.

  FIG. 14 shows an operation when the user terminal 101 tries to start communication using a packet bearer after a TCP session is established between the casting application 122 and the casting server 102. Although FIG. 13 shows communication between the browser 124 and the WWW server 123 as this communication, other communication may be used.

  In such a case, the casting application 122 does not interrupt the communication with the casting server 102 and continues to request transmission of multi-part content and receive multi-part content. On the other hand, other communications are also performed in parallel without delaying the start of other communications. In order to perform parallel communication using one PDP, a plurality of ports are used. Further, parallel communication may be performed using a plurality of PDPs.

  If the start of another communication is delayed, the user's intention cannot be immediately made. However, according to the present embodiment, the start of the other communication is not delayed. become able to.

  Also, if the transmission request of multi-part format content and the reception of multi-part format content are interrupted, a series of communications from the establishment of the TCP session must be performed again, and the casting application 122 Will be complicated. In this embodiment, since the request for transmitting the multi-part format content and the reception of the multi-part format content are continued, the operation of the casting application 122 is not complicated.

  In addition, since the voice call is performed using a voice / bearer different from the packet bearer, the communication related to the multi-part format content and the voice call can be performed simultaneously and independently.

  The present invention can be used for distributing content to user terminals.
