  DESCRIPTION OF EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. In the description of the drawings, the same elements are denoted by the same reference numerals, and redundant description is omitted.

  FIG. 1 shows a configuration of a content distribution system 1 according to the present invention. As shown in FIG. 1, the content distribution system 1 is configured to include a content relay server 10 according to the present invention, a mobile terminal 20, and a content server 30, and in response to a request from the mobile terminal 20 In this system, content is distributed from the server 30.

  The content here refers to sentences, images and the like expressed in digital data, which are displayed on the display device 21 provided in the mobile terminal 20 and can be visually recognized. In addition, the content includes a link, and by designating the link on the mobile terminal 20, another content acquisition request can be made. However, the content distributed in the content distribution system 1 does not include a link, and may simply include content that is a link destination. Specifically, the content corresponds to document data (HTML file) described in, for example, HTML (HyperText Markup Language). In the case of an HTML file, the link is included as a URL (Uniform Resource Locator) that is information for specifying a location on the network. In addition to the HTML file, the content may be image data in which a link is embedded as data. In the following description, it is assumed that the content is an HTML file.

  Hereinafter, each component of the content distribution system 1 will be described. The content relay server 10 is connected to the mobile terminal 20 and the content server 30 via a network, and is a device that relays data between the mobile terminal 20 and the content server 30. The content relay server 10 receives a content acquisition request from the mobile terminal 20 and acquires content related to the acquisition request from the content server 30. The content relay server 10 generates content in which the display position of the link included in the content is changed, and transmits the generated content to the mobile terminal 20. The functional configuration of the content relay server 10 and the display position changing process will be described later in more detail. Specifically, the content relay server 10 is realized by a server device including hardware such as a CPU (Central Processing Unit), a memory, a storage, and a communication module. The content relay server 10 is preferably included in the function of a proxy server provided for the mobile terminal 20 to access the content server 30.

  The portable terminal 20 is an information terminal operated by a user, and can display the acquired content with the display device 21. The mobile terminal 20 has a data communication function, and can be connected to the content relay server 10 via the network N as shown in FIG. The content is acquired from the content server 30 by transmitting a content acquisition request to the content relay server 10 using this communication function. For example, when the content is an HTML file, as shown in FIG. 2, character information such as “sports” and “weather” is displayed on the display device 21 of the mobile terminal 20 in order from the top for each line. In addition, each of the above displays is associated with a link, and the information for each line is selected (indicating that “News” is outlined), and the user clicks, etc. The content acquisition request related to the link is transmitted to the content relay server 10. The mobile terminal 20 is provided with information for specifying the mobile terminal 20 such as a telephone number.

  Specifically, the portable terminal 20 includes hardware such as a CPU (Central Processing Unit), a memory, a storage, and a communication module. Specifically, for example, a mobile phone corresponds. The network N is preferably a mobile communication network. Alternatively, the portable terminal 20 may be a PDA (Personal Digital Assistance) or the like, and may not be a portable one such as a PC (Personal Computer). Further, the network N may be a wired network such as the Internet other than the mobile communication network. Although only one mobile terminal 20 is illustrated in FIG. 1, the content distribution system 1 usually includes a plurality of mobile terminals 20.

  The content server 30 is a device that stores content. Further, the content server 30 transmits content to the mobile terminal 20 or the like in response to a request via a network such as the Internet. In the present embodiment, the content server 30 is connected to the content relay server 10 via a network such as the Internet, and transmits content to the mobile terminal 20 via the content relay server 10. Specifically, the content server 30 corresponds to, for example, a web server that stores a web page composed of an HTML file and transmits the web page in response to a request. Although only one content server 30 is illustrated in FIG. 1, the content distribution system 1 usually includes a plurality of content servers 30.

  Hereinafter, each function of the content relay server 10 will be described. As shown in FIG. 1, the content relay server 10 includes an access number database 11, a reception unit 12, a terminal information acquisition unit 13, a database update unit 14, a content conversion unit 15, and a transmission unit 16. The

  The number-of-accesses database 11 is a database that stores information for identifying content and the number of accesses from the content to the linked content for each portable terminal 20. Specifically, the access number database 11 holds information by storing each data in the table 52 shown in FIG. The table 52 is prepared for each mobile terminal 20, and for each table 52, for example, which table 52 is associated with which mobile terminal 20 is associated with terminal information that identifies the mobile terminal 20 such as a telephone number. Can be judged.

  As shown in FIG. 3, the table 52 stores “URL of link source content”, “URL of link destination content”, and “number of accesses” in association with each other. “URL of link source content” is information for specifying the content of the link source. “URL of link destination content” is information for specifying the content related to the link included in the link source content, that is, information for specifying the link destination content. The “number of accesses” is the number of times that the mobile terminal 20 uses the link of the link source content and makes an acquisition request for the link destination content, that is, the link source content is accessed from the link of the link source content. It is the number of times. Specifically, the data shown in the first line of the table 52 in FIG. 3 indicates that the mobile terminal 20 specified by the telephone number “090-XXXX-XXXX” has the URL “http: //abc.de.fg/index”. The content (link destination content) specified by the URL “http: //abc.de.fg/a.html” is accessed once from the link of the content (link source content) specified by “.html”. Show.

  The access number database 11 is implemented by using, for example, a relational database. Data stored in the access number database 11 is updated by the database update unit 14.

  The receiving unit 12 is a receiving unit that receives an acquisition request for the content including information for specifying the content from the mobile terminal 20. The receiving unit 12 also receives information for specifying the link source content together with the content acquisition request. Reception is performed via the network N. The information specifying the content corresponds to, for example, the above URL, and is preferably included in the above content acquisition request. When the mobile terminal 20 does not transmit the acquisition request via the content link, the reception unit 12 does not receive information specifying the link source content or receives information that there is no link source content. Is done. The acquired information is transmitted to the database update unit 14 in order to update the access number database 11, and is also transmitted to the content conversion unit 15 in order to acquire content related to the acquisition request.

  The terminal information acquisition unit 13 is a terminal information acquisition unit that acquires terminal information for specifying the mobile terminal 20 that has transmitted the content acquisition request. The terminal information specifically corresponds to the above telephone number or the like. Acquisition of terminal information may be performed with reference to an acquisition request received by the receiving unit 12 or may be acquired from a network N that is a mobile communication network, for example. The acquired terminal information is transmitted to the database update unit 14 in order to update the access number database 11.

  The database update unit 14 is a database update unit that receives the terminal information from the terminal information acquisition unit 13 and the information specifying the link source and the link destination content from the reception unit 12 and updates the access number database 11. Specifically, the update is a process of increasing the number of accesses related to the terminal information, the link source and the link destination content in the table 52 of the access number database 11 by “1”.

  The content conversion unit 15 changes the display position of the link included in the content related to the content acquisition request based on the number of accesses to the link destination content stored in the access number database 11 regarding the content related to the content acquisition request. Content conversion means for generating content. It is assumed that the display position is changed according to a predetermined rule and contributes to improving the convenience of the user's content browsing, such as arranging a large number of accesses at a position where the user can easily browse the content. A specific method for changing the display position will be described later. The generated content is transmitted to the transmission unit 16 for transmission to the mobile terminal 20. The content conversion unit 15 is also a content acquisition unit that acquires content related to a content acquisition request.

  The transmission unit 16 is a transmission unit that transmits the content generated by the content conversion unit 15 to the portable terminal 20 as the content related to the content acquisition request. Transmission is performed via the network N.

  Subsequently, processing in the content distribution system 1 will be described focusing on processing executed by the content relay server 10 according to the present embodiment. This process is a series of processes from the time when the mobile terminal 20 makes a content acquisition request until the content related to the acquisition request is acquired. This process is roughly divided into “the access number database 11 in the content relay server 10. The update process "and the" process for generating the content whose link display position has been changed and transmitting it to the portable terminal 20 "are included. Hereinafter, the two processes will be described separately for easy understanding.

  First, the process of updating the access number database 11 will be described with reference to the sequence diagram of FIG. First, the mobile terminal 20 transmits a content acquisition request to the content relay server 10 via the network N (S01). The content acquisition request is transmitted with a user operation as a trigger. For example, it is performed by designating a link of content displayed on the display device 21 of the mobile terminal 20 (this content is acquired in advance by this processing or the like). This content acquisition request includes the URL of the content (link destination content) related to the acquisition request, the URL of the link source content, and the telephone number (terminal information) of the mobile terminal 20. Specifically, for example, when the content shown in FIG. 2 is displayed on the mobile terminal 20 and the link of “Sweep Prize” is selected and designated from there, “URL related to the content of“ Sweep Prize ””, “Display” The URL of the content ”and the telephone number of the portable terminal 20 are transmitted. When the user makes a content acquisition request by inputting a URL or the like, the URL of the link source content is not included in the acquisition request. In the content relay server 10, the receiving unit 12 receives the content acquisition request transmitted from the mobile terminal 20.

  Subsequently, in the content relay server 10, the terminal information acquisition unit 13 refers to the acquisition request received by the reception unit 12 and acquires the telephone number of the mobile terminal 20 that has made the content acquisition request (S02). The telephone number may be acquired from the network N.

  Subsequently, the URL of the link destination content and the link source content is transmitted from the reception unit 12, and the telephone number of the mobile terminal 20 is associated with the terminal information acquisition unit 13 and transmitted to the database update unit 14. The database update unit 14 receives the information and updates the access number database 11 based on the information (S03). Specifically, the number of accesses related to the terminal information, the link source and the link destination content is increased by “1”. In the specific example of FIG. 2 described above, the number of accesses related to the link destination content of the “stakes” of the content (link source content) displayed as shown in FIG. Here, it is assumed that the number of accesses related to other linked content is “0”. If there is no record to be updated (in this case, for example, the database update unit 14 confirms that there is no record in response to an inquiry to the access count database 11 that “the record does not exist”. It is preferable to generate a record to be updated without performing update processing.

  The process for updating the access number database 11 has been described above. Hereinafter, a process of generating content in which the display position of the link is changed and transmitting it to the mobile terminal 20 will be described using the sequence diagram of FIG.

  First, the transmission of the content acquisition request by the mobile terminal 20 described above and the reception of the content acquisition request by the content relay server 10 are common to the processing of S01 described above. Here, the reception unit 12 transmits the received content acquisition request to the content conversion unit 15.

  Subsequently, the content conversion unit 15 refers to the content acquisition request (the URL of the link destination content included therein) and transmits a content transmission request related to the content acquisition request to the content server 30 (S04). The content server 30 receives the transmission request and transmits the content related to the transmission request to the content relay server 10 (S05). In the content relay server 10, the content conversion unit 15 receives the content transmitted from the content server 30.

  Subsequently, the content conversion unit 15 refers to the access number database 11 and generates content in which the display position of the link of the received content is changed (S06). The content in which the link display position is changed is generated, for example, as follows. First, records for all link destination contents stored in the access count database 11 and whose content related to the content acquisition request is the link source content are acquired. Subsequently, by referring to this record, contents rearranged so that links are displayed in descending order from the top are generated. Specifically, when the “Sweep Prize” link is designated (clicked) in the previous access as in the example using FIG. 2 described above, the number of accesses of the “Sweep Prize” link is larger than the other links. Therefore, the content is generated so that the link of the “sweep prize” is displayed at the top. In addition to rearranging the content in the order of the number of accesses, for example, a content having a large number of accesses may be arranged at a location that is easily noticeable by the user in the content layout.

  The generated content is transmitted to the transmission unit 16, and is transmitted to the mobile terminal 20 related to the content acquisition request by the transmission unit 16 (S07). The portable terminal 20 receives the content and displays it on the display device 21 (S08). For example, as shown in FIG. 6, in the above example, the “stakes” link is displayed at the top.

  The above is the processing for generating the content in which the display position of the link is changed. The process of generating the content in which the display position of the link is changed can be executed even when the information for specifying the link source content is not included in the content acquisition request.

  In the process of S06, when there is no record to be referenced in the table of the access number database 11 such as when the link source content is accessed for the first time by the mobile terminal 20, the content conversion unit 15 In response to the inquiry to the database 11, it can be known that there is no record by replying that “the record does not exist”. Here, a new record is generated. The record is generated using, for example, the link source content acquired in S04 and S05. At this time, it is preferable to acquire a URL related to the link by extracting an anchor tag or the like and generate records relating to all link destinations of the link source content. For example, the URL of the link source content (content displayed as shown in FIG. 2 in the above specific example) is “http: //opq.rs.tu/index.html”, and the link of the content is related The URLs (URLs of linked contents such as “news”, “weather”, “sweepstakes” in the specific example of FIG. 2) are “http: //opq.rs.tu/a.html”, “http: / In the case of “/opq.rs.tu/b.html”, “http: //opq.rs.tu/c.html”, etc., a record 53 of the table 52 shown in FIG. 3 is generated. “0” is registered for all the access numbers of the generated records. In this case, the content with the link position changed in S06 is not generated, and the content acquired in S04 and S05 is transmitted to the mobile terminal 20.

  In addition, the two processes described above (the process of updating the access number database 11 and the process of generating content in which the display position of the link is changed) are a series of processes, but since they are not related to each other after S01, Such a process may be performed first, or two processes may be performed in parallel.

  As described above, according to the present embodiment, as the number of accesses from the mobile terminal 20 increases, the link can be arranged at a position where the user can easily specify browsing or clicking. Therefore, the access tendency for each portable terminal 20, that is, the content in which links are arranged in accordance with the interests of the individual users, is transmitted, and the convenience of content browsing for the individual users can be improved.

  In particular, in a portable terminal 20 such as a mobile phone or a PDA where the display range of the display device 21 is not as wide as a PC monitor or the like, it is easy to view and specify the link position, which improves convenience. Greatly contributes.

  Further, instead of simply changing the link position from the number of accesses as in the above-described embodiment, the access probability for each link is calculated based on information received by the receiving unit 12 and a predetermined rule, The link display position may be determined based on the access probability. For example, the present invention may be implemented in the following forms. Note that the access probability here is not necessarily a mathematical probability, and includes a parameter indicating the degree of access to the linked content.

ここで、ΔＰ（ｉ）はリンクＬ_ｉのアクセス確率Ｐ（ｉ）の更新量を表す。上からｊ番目に表示されるリンクＬ_ｊが指定（クリック）されたときの更新量ΔＰ（ｉ）は、以下の（２）式により表される。

なお、アクセス確率Ｐ（ｉ）の初期値は０である。 The access probabilities shown below are for those in which links are displayed in order from the top like the content displayed in FIG. In the link source content, let the link displayed i-th from the top be L _i (0 <i <N + 1). Here, N is the total number of links included in the link source content. If the total number of accesses from the link source content to the link destination content is K times, the link access probability P (i) in the link source content is updated using the following equation (1).

Here, [Delta] P (i) represents the amount of updated access probability P (i) of the link _{L i.} The update amount ΔP (i) when the _jth link L _j displayed from the top is designated (clicked) is expressed by the following equation (2).

Note that the initial value of the access probability P (i) is zero.

Usually, since the user browses the link from above, the link L _i (i <j) displayed above the link L _j is browsed by the user, but is not selected because it is not selected. It is considered to be a link, and the update amount ΔP (i) is set to zero. In addition, the link L _i (i> j) displayed below the link L _j is highly likely not to be viewed by the user, and it cannot be determined whether or not the link is unnecessary for the user, so the update amount ΔP (i ) Is ½. In particular, in the portable terminal 20 such as a mobile phone or a PDA in which the display range of the display device 21 is limited, the display device 21 may not be displayed.

  Since the content relay server 10 knows in what order the links are arranged, the database update unit 14 specifies the content related to the acquisition request by holding the above-described rules. The access probability can be calculated using the information received by the receiving unit 12 such as information.

  Thus, the calculated access probability P (i) is stored in the table 62 as shown in FIG. The access probability P (i) is stored in association with information specifying link source content (omitted in FIG. 7) and information specifying link destination content, as in the above-described embodiment. The table 62 is provided for each mobile terminal 20 (information for specifying the mobile terminal 20 in the table 62 shown in FIG. 7 is omitted).

  The update of the access probability is performed at the update timing of the access number database 11 in the above-described embodiment (S03), and the content conversion unit 15 changes the display position of the link (S06) This is done with reference to the probability. It is assumed that the display position is changed according to a predetermined rule and contributes to the improvement of the convenience of the user's content browsing, such as placing an item having a high access probability at a position where the user can easily browse the content. The change of the display position of the link is, for example, such that the links are displayed in descending order of access probability. In addition to this, for example, a content having a high access probability may be arranged in a location that is easily noticeable by the user in the content layout.

  A specific example of updating the access probability and changing the display position of the link will be shown. Assume that the access probability P (i) to each link destination content in the same link source content is shown in FIG. 7A, and the total number of accesses to the link destination content is zero. Here, it is assumed that the links are displayed in the order of the table in FIG. 7A from the top, that is, “1”, “2”, “3”, “4”, “5”, “6”. . When this display is old and a link of “4” is designated, the update amount ΔP (i) of the access probability P (i) of each link is calculated by the above equation (1) and is shown in FIG. It becomes like this. Based on the update amount ΔP (i), the access probability P (i) is updated and becomes as shown in FIG. Therefore, when the link source content is accessed next from the same portable terminal 20, the access probability P (i) is in descending order, that is, “4”, “5”, “6”, “1”, “2”. , Contents to be displayed in the order of “3” are generated. Next, when the link “6” is designated, the access probability P (i) is updated in the same manner as described above, as shown in FIG.

  Further, in the example of the display of FIG. 2 used in the above-described embodiment, when the “Sweep Prize” link is designated, the link (“News” to “Learning”) displayed above the “Sweep Prize” link is displayed. The access probability of the link (link) is 0, and the access probability of the link (the link from “recruitment” to “coupon”) displayed below the “sweepstakes” link is ½. When the link source content is next accessed from the same mobile terminal 20, the link displayed below the "Swee" link is displayed above the "Swee" link as shown in FIG. Content whose display position has been changed so as to be displayed above the link is generated. The link that was displayed above the “Sweepstakes” link is considered to be a less-needed link for the user because it is located in a position more visible to the user than the “Sweepstakes” link but is not specified. , The access probability of those links can be set low and can be displayed in the lower order. On the other hand, the links displayed below the “Sweepstakes” link may not have been seen by the user and may be a link that is highly necessary for the user. Can be set high and displayed at the top.

  According to the embodiment using the above access probability, a link that has not been designated is also weighted under a predetermined condition and considered. Therefore, for example, in the mobile terminal 20 with a limited display range, a link that does not enter the display range and has not been browsed by the user unless scrolling can be arranged at the top. That is, it is possible to further improve the convenience of content browsing for each user, such as displaying a link that has not been seen by the user due to screen restrictions and function restrictions on the mobile terminal 20 at a position that is visible to the user.

  Note that when the access probability is used as described above, it is not always necessary to store the access count of each link in the access count database 11. Further, it is not always necessary to use the above rule for updating the access probability. For example, the update amount ΔP (i) when (i> j) in equation (2) may be an arbitrary real number between 0 and 1.
