The mobile device 10 will be described. As shown in FIG. 1, the mobile device 10 is configured to be capable of wireless communication with the base station B, and transmits an HTTP request (described later) and receives an HTTP response via the base station B and the network N. The mobile device 10 is, for example, a mobile phone having both a voice communication function and a data communication function, and any applicable communication method such as a PDC (Personal Digital Cellular) method or a CDMA (Code Division Multiple Access) method is arbitrary. .
[0032]
The mobile device 10 includes, as functional components, a communication control unit 11 (corresponding to a receiving unit), a position information storage unit 12, an input unit 13, and a display content storage determination unit 14 (corresponding to a storage determination unit). , A display content storage unit 15 (corresponding to storage means), a display content display determination unit 16 (corresponding to display determination means), and a display unit 17 (corresponding to display means).
[0033]
Here, the position information storage unit 12 and the display content storage unit 15 correspond to internal memories such as an EEPROM (Electrically Erasable and Programmable Read Only Memory) as physical components. The display unit 17 also corresponds to a display device such as an LCD (Liquid Crystal Display) as a physical component. The communication control unit 11, the input unit 13, the display content storage determination unit 14, and the display content display determination unit 16, which are other components, are configured such that software stored in the built-in memory is executed by a CPU (Central Processing Unit). Realized by being executed.
[0034]
Hereinafter, each component of the mobile device 10 will be described in detail.
The communication control unit 11 communicates with the base station B. Specifically, the communication control unit 11 extracts the identification information of the base station B from the broadcast information received from the base station B, and stores the identification information in the position information storage unit 12 as position information. The communication control unit 11 transmits an HTTP request, which is a transmission request for a Web page (corresponding to display data), and receives an HTTP response such as a Web page in accordance with the content of an instruction from the input unit 13.
[0035]
The location information storage unit 12 stores the identification information of the base station B extracted from the broadcast information by the communication control unit 11 as location information.
The input unit 13 is an interface used when a user inputs various information such as a URL (Uniform Resource Locator) such as a button and a dial. The input unit 13 instructs the communication control unit 11 to acquire a web page according to a user operation, and notifies the display content display determination unit 16 that the web page acquisition is instructed.
[0036]
The display content storage determination unit 14 executes a display content storage determination process, which will be described later, so that the display content (corresponding to content data) included in the Web page received by the communication control unit 11 is in a data format, an encoding format, or the like. When the various conditions are satisfied, the display content is extracted from the Web page and stored in the display content storage unit 15.
[0037]
The display content storage unit 15 stores the display content that is determined to be stored as a result of the storage permission determination by the display content storage determination unit 14. Further, the display content storage unit 15 holds in advance default content as content that is displayed when there is no displayable content among the display content acquired from the Web server 20.
[0038]
When the display content display determination unit 16 receives a notification from the input unit 13 that the acquisition of the Web page has been instructed, the display content display determination unit 16 determines whether or not to display the display content stored in the display content storage unit 15. If the display content to be determined is within the expiration date and has not reached the scheduled display count, it is displayed on the display unit 17 and the expiration date has passed or the scheduled display count has been reached. If so, the existing default content is displayed.
[0039]
The display unit 17 displays the content instructed to be displayed by the display content display determination unit 16. That is, the display unit 17 displays the display content that is permitted to be displayed as a result of the display permission / inhibition determination, and displays the default content instead of the display content that is denied to be displayed.
[0040]
The proxy server 20 includes, as functional components, a Web page storage unit 21, a display content storage unit 22, a Web page transmission unit 23 (corresponding to a transmission unit), and a display content selection unit 24 (corresponding to a selection unit). With.
[0041]
The web page storage unit 21 stores a web page transmitted as an HTTP response corresponding to the HTTP request of the mobile device 10 in an updatable manner. This Web page is stored in a state before the display content is incorporated so that the display content to be incorporated can be appropriately changed.
[0042]
In the display content storage unit 22, display content that is incorporated into a Web page and transmitted to the mobile device 10 is stored in association with the display content name so as to be updatable. The display content has a predetermined data format (attribute is type) such as TEXT, JPEG (Joint Photographic Experts Group), and GIF (Graphic Interchange Format), and a predetermined encoding format (attribute encoding) such as BASE64. In addition, the display content is set so that the current time (attribute time), the start date / time of the expiration date (attribute not-before), the end date / time of the expiration date (attribute not-after), and the scheduled display count (attribute loop) can be updated Has been. The display content name is information that can uniquely identify the display content to be transmitted. For example, when the display content is related to the weather, the display content name is “weather_a”, and when the display content is related to the event, “event_a_1”, “event_a_2”, and “event_a_3”. The display content is not limited to weather and events, and may be news.
[0043]
When receiving the HTTP request from the mobile device 10, the Web page transmission unit 23 acquires the Web page specified by the HTTP request from the Web page storage unit 21. The Web page can be specified by, for example, a URL specified by an HTTP request. Further, the Web page transmission unit 23 incorporates the display content selected by the display content selection unit 24 into the Web page, and transmits this Web page to the mobile device 10 as an HTTP response.
[0044]
The display content can be incorporated into the Web page using a specific tag called X-HIDDEN. For example, the display content of text data “Today's weather is cloudy and clear” is incorporated into the Web page specified by the URL “http://www.docomo.ne.jp/link1.html”. The source code is shown in FIG. In FIG. 2, the display content is text data, but it may be image data. X-HIDDEN can be recognized by the mobile device 10 and instructs storage of data described between <X-HIDDEN> and </ X-HIDDEN> but does not instruct display during reception.
[0045]
The display content selection unit 24 has a reference table 241. FIG. 3 is a diagram illustrating an example of display content names stored in the reference table 241. As shown in FIG. 3, the reference table 241 has a position information storage area 241a, a display content type area 241b, and a display content name area 241c.
[0046]
The position information storage area 241a stores position information (for example, C1, C2) that is a target for collation of position information transmitted from the mobile device 10 as a part of the HTTP request.
In the display content type area 241b, the type of content (for example, weather, event) that the display content stored in the display content storage unit 22 presents to the user of the mobile device 10 is stored as “display content type”. .
[0047]
In the display content name area 241c, identification information for specifying the display content acquired from the display content storage unit 22 is stored as a “display content name”. For example, “weather_a” is stored as the display content name when the position information is “C1” and the display content type is “weather”, and the Web page for which the display content specified by this display content name is requested Will be incorporated into.
[0048]
The display content selection unit 24 refers to the reference table 241 and acquires the display content addressed to the mobile device 10 from the display content storage unit 22. That is, when the display content selection unit 24 acquires the location information of the mobile device 10 from the HTTP request received by the Web page transmission unit 23, one display content name from among a plurality of display content names corresponding to the location information. Select. Then, the display content corresponding to the selected display content name is acquired from the display content storage unit 22.
[0049]
Here, the display content name to be selected is sufficient if it corresponds to the position information included in the HTTP request, and it is arbitrarily set whether to select the display content name corresponding to the display content type of weather or event. Is possible. With respect to the HTTP request from the mobile device 10, for example, the display content type of the weather and the event may be determined alternately or may be determined randomly. Further, even when a display content type having a plurality of display content names (event in this embodiment) is determined, the display content names may be selected sequentially or randomly.
[0050]
Next, the operation of the display control system 1 will be described, and a display control method according to the present invention will be described. FIG. 4 is a flowchart for explaining the content display control process executed by the display control system 1.
[0051]
First, in S <b> 1, a radio channel is established between the mobile device 10 and the proxy server 20 in accordance with an instruction from the user of the mobile device 10. As a result, signal transmission / reception between the mobile device 10 and the proxy server 20 via the base station B and the network N becomes possible.
[0052]
In S2, an HTTP request is transmitted from the mobile device 10 to the proxy server 20 using the wireless channel established in S1.
In S3, the proxy server 20 executes display content incorporation processing described below based on the position information included in the HTTP request transmitted in S2.
[0053]
The display content incorporation process will be described in detail with reference to FIG.
First, in S <b> 31, the Web page transmission unit 23 acquires a Web page corresponding to the HTTP request received in S <b> 2 from the Web page storage unit 21. In S32, the display content selection unit 24 acquires the location information of the mobile device 10 from the HTTP request similarly received in S2.
[0054]
Subsequently, the display content selection unit 24 determines the display content type of the display content to be incorporated into the Web page (S33). By this process, the display content corresponding to the position information acquired in S32 and the display content type determined in S33 becomes a selection candidate (S34). For example, when the mobile device 10 is located in the area identified by the position information “C2” and the display content type is determined to be “event”, the display content name “event_b_1” as shown in FIG. , Display content having “event_b_2” is a selection candidate.
[0055]
In S35, the display content selection unit 24 determines whether there are a plurality of display content selection candidates in S34. As a result of the determination, if there are a plurality of display content selection candidates, the display content selection unit 24 further selects display content to be incorporated into the Web page from the selection candidates (S36). For example, when display contents having display content names “event_b_1” and “event_b_2” are listed as display content selection candidates, one of these display contents is selected.
[0056]
On the other hand, if the result of determination in S35 is one display content selection candidate, the display content selection unit 24 determines the display content of the selection candidate as display content to be incorporated into the Web page (S37).
[0057]
In S <b> 38, the display content selection unit 24 acquires the display content selected in S <b> 36 or confirmed in S <b> 37 from the display content storage unit 22.
Then, after acquiring the display content acquired in S38 from the display content selection unit 24, the Web page transmission unit 23 incorporates the display content in the Web page acquired in S31 (S39). With this process, the display content incorporation process is terminated.
[0058]
Returning to FIG. 4, in S <b> 4, the Web page in which the display content is incorporated in S <b> 39 is transmitted from the proxy server 20 to the mobile device 10 as an HTTP response. This transmission is performed via the network operator network N and the base station B.
[0059]
In S5, the display content is extracted and stored from the HTTP response received by the communication control unit 11. Prior to this process, the display content storage for determining whether or not the display content is stored is stored. Judgment processing is executed.
[0060]
Hereinafter, the display content storage determination process executed and controlled by the display content storage determination unit 14 will be described in detail with reference to FIG. First, in S51, the display content storage determination unit 14 determines whether or not the URL of the reception destination (transmission source) of the Web page received as an HTTP response in S4 is registered in the mobile device 10 in advance. That is, the mobile device 10 holds the URL of the Web page having the display content to be stored in advance, and the process proceeds to the subsequent S52 only when the destination URL of the received Web page is held. . When the destination URL is not held in the mobile device 10, the display content storage determination process ends, and the display content is not stored.
[0061]
In the present embodiment, the URL of the proxy server 20 is registered in the mobile device 10 as the reception destination URL. As described above, the display content stored in the display content storage unit 15 is limited by limiting the destination URL that is the storage target of the display content. Therefore, for example, undesirable display contents that are contrary to public order and morals are not stored in the mobile device 10 via the Web page. Along with this, the display content is also prevented from being displayed on the mobile device 10.
[0062]
In S52, the display content storage determination unit 14 determines whether or not the above-described X-HIDDEN tag is described in the Web page received as the HTTP response in S4. As a result of the determination, if the X-HIDDEN tag is not described (S52; No), since the display content does not exist in the received Web page, the display content storage determination unit 14 displays the display content. The display content storage determination process is terminated without storing.
[0063]
On the other hand, as a result of the determination in S52, if the X-HIDDEN tag is described (S52; Yes), the display content storage determination unit 14 converts the data format of the display content incorporated in the Web page by the tag. It is determined whether or not the mobile device 10 is compatible (S53). If the mobile device 10 does not support the data format as a result of the determination (S53; No), the mobile device 10 cannot display even if the display content is stored, so the display content is not stored. The display content storage determination process ends. At this time, the display content storage determination unit 14 may discard the display content.
[0064]
As a result of the determination in S53, when the mobile device 10 supports the data format of the display content (S53; Yes), the display content storage determination unit 14 indicates that the mobile device 10 corresponds to the encoding format of the display content. It is determined whether or not (S54). If the mobile device 10 does not support the encoding format as a result of the determination (S54; No), the mobile device 10 cannot display the display content even if it is stored, so that the display content is not stored. The display content storage determination process ends. At this time, the display content storage determination unit 14 may discard the display content.
[0065]
On the other hand, if the result of determination in S54 is that the mobile device 10 is compatible with the display content encoding format (S54; Yes), this display content can be displayed. It is determined whether or not display content can be stored. In other words, the display content storage determination unit 14 compares the size relationship between the data capacity (free data capacity) that can be newly stored in the display content storage unit 15 and the data capacity of the display content incorporated in the Web page. Then, it is determined whether or not the content can be stored in the display content storage unit 15 (S55).
[0066]
As a result of the determination, if the data capacity of the display content is larger than the free data capacity and the free data capacity is insufficient (S55; No), the mobile device 10 cannot store the display content. Is discarded, and the display content storage determination process is terminated.
[0067]
On the other hand, as a result of the determination in S55, when the data capacity of the display content is smaller than the free data capacity and the free data capacity is sufficient (S55; Yes), the display content can be both displayed and stored. The content storage determination unit 14 stores the display content in the display content storage unit 15 (S56). With this process, preparation for displaying the display content during the connection process to the wireless channel by the mobile device 10 is completed.
[0068]
In S <b> 6, when the user of the mobile device 10 instructs to disconnect the wireless channel with the end of browsing the Web page, the wireless channel established in S <b> 1 between the mobile device 10 and the proxy server 20 is temporarily disconnected.
[0069]
In S7, the display content display determination unit 16 waits for an instruction to connect to the wireless channel. FIG. 7A shows a screen 171 displayed on the display unit 17 while waiting for the channel connection instruction. For example, when the user of the mobile device 10 selects “1.iMenu” with the input unit 13 to view the Web page, the display content display determination unit 16 detects this as a channel connection instruction (S7; Yes). Then, the display content display determination process described below is executed.
[0070]
Hereinafter, the display content display determination process executed and controlled by the display content display determination unit 16 will be described in detail with reference to FIG. First, in S <b> 81, the display content display determination unit 16 determines whether or not display content is stored in the display content storage unit 15. If the display content has already been stored as a result of the determination (S81; Yes), the display content display determination unit 16 compares the current time set for the display content with the end date and time of the expiration date. Then, it is determined whether or not the display content is within the expiration date (S82).
[0071]
As a result of the determination, if the display content is within the expiration date (S82; Yes), the display content display determination unit 16 determines whether or not the scheduled display count N is set for the display content (S83). ). As a result of the determination, if the scheduled display count N is set for the display content (S83; Yes), the display content display determination unit 16 determines whether the scheduled display count N is greater than 0 (S84). .
[0072]
As a result of the determination, if the scheduled display count N is greater than 0 (S84; Yes), the display content display determination unit 16 determines the current display from the scheduled display count N because there is a remaining display content scheduled display count. After subtracting 1 for processing (S85), display content is displayed on the display unit 17 (S86). With this display process, the display content display determination process ends.
[0073]
As a result of the determination in S83, if the scheduled display count N is not set for the display content (S83; No), the display content can be displayed indefinitely as long as it is within the expiration date, so the processing of S84 and S85 Is omitted and the display process proceeds to S86. FIG. 7B shows a screen 172 displayed on the display unit 17 during the connection processing to the wireless channel in S86. In the present embodiment, the mobile device 10 acquires a Web page in which text data “Today's weather is cloudy and clear” is incorporated as display content when the channel is connected last time. Accordingly, the text data 172a is displayed on the foreground of the display unit 17.
[0074]
Furthermore, if the display content is not stored in the display content storage unit 15 as a result of the determination in S81 (S81; No), the display content display determination unit 16 causes the display unit 17 to display the default content instead. (S87). Similarly, when the display content has passed its expiration date (S82; No) and when the scheduled display count is 0 or less (S84; No), the display content display determination unit 16 displays the display content. The default content is displayed on the display unit 17 instead of the content (S87). As a result, it is possible to display content data during the channel connection process regardless of whether the acquired display content is present, valid or invalid.
[0075]
Returning to FIG. 4, in S9, the wireless channel is established again in response to the channel connection instruction (S7). When the wireless channel is established, reception of the web page requested by the mobile device 10 is completed. When the reception of the Web page is completed, the display of the display content displayed in S86 of FIG. 8 or the default content displayed in S87 ends, and the Web page is displayed. FIG. 7C shows a screen 173 displayed immediately after the wireless channel is established by the mobile device 10.
[0076]
Thereafter, the processes after S10 are continuously executed, but the processes of S9 to S13 are the same as the processes shown in S1 to S5, respectively, and thus detailed description thereof is omitted. Upon completion of the processing in S13, new display content different from the display content stored in S5 is stored. This display content is used as content data displayed during the next channel connection process by the mobile device 10.
[0077]
As described above, according to the display control system 1 according to the present invention, when the mobile device 10 requests the proxy server 20 to transmit a Web page, the proxy server 20 displays display content according to the position of the mobile device 10. It is described on the Web page and transmitted to the mobile device 10. Thereafter, when the mobile device 10 executes the connection process to the wireless channel, the mobile device 10 displays the display content during the execution. Thereby, the display content displayed in the waiting time differs for each connection process depending on the timing and place where the mobile device 10 acquires the Web page from the proxy server 20. Therefore, it is possible to present information useful to the user as compared with the case where the existing content data is displayed on the mobile device 10.
[0078]
Preferably, the mobile device 10 does not store all display contents included in the acquired Web page, but stores only display content that can be displayed and stored on the mobile device 10. This prevents display content that is not used from being stored and waste of free data capacity. Further, by giving a predetermined limit to the display period and the number of times of display content, it is possible to avoid storing or displaying display content that is no longer needed.
[0079]
Next, a content display control process program for causing the mobile device 10 to execute the series of content display control processes described above will be described. As shown in FIG. 9, the content display control processing program 31 is stored in a program storage area 30 a formed on the recording medium 30. The content display control processing program 31 includes a main module 31a that centrally controls content display control processing, a reception module 31b, a storage module 31c, a display module 31d, a storage determination module 31e, and a display determination module 31f. As a structural unit.
[0080]
The function realized by executing the reception module 31 b is the same as the function of the communication control unit 11 of the mobile device 10. For example, the reception module 31b receives a Web page including display content transmitted from the proxy server 20. The data stored by executing the storage module 31 c is the same as the data stored in the display content storage unit 15. The data displayed by executing the display module 31d is the same as the data displayed on the display unit 17. The function realized by executing the storage determination module 31e is the same as the function of the display content storage determination unit 14.
[0081]
The function realized by executing the storage determination module 31e is the same as the function of the display content storage determination unit 14. For example, when the display content included in the received Web page is data that can be displayed on the display unit 17, the storage determination module 31 e stores the display content in the display content storage unit 15. The function realized by executing the display determination module 31 f is the same as the function of the display content display determination unit 16. For example, the display determination module 31 f causes the display unit 17 to display the display content when the display content stored in the display content storage unit 15 is data within the expiration date. In addition, the display determination module 31 f causes the display unit 17 to display the display content when the number of display times set for the display content stored in the display content storage unit 15 remains.
[0082]
The content display control processing program 31 is transmitted in whole or in part via a transmission medium such as a communication line, and received and recorded (including installation) by an information communication device including the mobile device 10. It is good.
[0083]
Note that the present invention is not limited to the above-described embodiments, and modifications can be appropriately made without departing from the spirit of the present invention. For example, the timing at which the mobile device 10 displays the display content is in the process of connecting to the communication line by the mobile device 10 in the above embodiment. However, the present invention is not limited to this timing, and the display content may be displayed until the Web page once displayed after connection is completed is switched to another Web page (during the transition process to the next screen). In this case, the execution of the display content display determination process is started not by an instruction to connect to a wireless channel but by an instruction to switch a Web page.
[0084]
Further, in the aspect in which the mobile device 10 displays the display content during the connection process to the wireless channel, not only when the acquisition of the same Web page as the previous connection is requested but also the Web page different from the previous connection Of course, the present invention can be applied to the case where the acquisition of the above is requested.
[0085]
【The invention's effect】
According to the present invention, after display data is received from the server device and content data included in the display data is stored in the storage unit, it is read from the storage unit during the connection process to the communication line of the mobile device. Content data is displayed on the display means. That is, as data displayed during the connection process to the communication line, the mobile device does not hold in advance, but the content data transmitted from the server device prior to the connection process is used. Therefore, it is possible to display variable data according to the timing and location at which the mobile device receives display data from the server device during the line connection process.
