Description

  The present invention relates to a mobile communication terminal such as a mobile phone that can acquire and display content summary information provided from a server on a communication network, and a server that can communicate with the mobile communication terminal.

  Non-Patent Document 1 describes software that receives and displays summary information of WEB content by a mobile phone as a mobile communication terminal. The summary information data of this WEB content is transmitted in a format called RSS, for example, in response to an acquisition request from the mobile phone. This RSS is an XML (Extensible Markup Language) based format in which metadata such as headings, summaries, and update information of web contents provided by a web server (web site) is structured and described. There are several versions of RSS (RSS0.9X, RSS1.0, RSS2.0, Atom). Each version is called “Rich Site Summary”, “Really Simple Syndication”, and “RDF Site Summary”. It is. The document described in the RSS format is called “RSS feed”, and the software that receives and displays the RSS feed is called “RSS reader”. When the WEB content is updated, an RSS feed reflecting the updated summary information of the WEB content is transmitted to the mobile phone in response to an acquisition request from the mobile phone.

  The RSS reader periodically accesses a WEB server on a communication network based on a URI (Uniform Resource Identifier), and automatically acquires an RSS feed from the server. If the WEB server side is temporarily down, the server cannot normally process the summary information acquisition request from the mobile phone, and the mobile phone cannot acquire the RSS feed. In addition, even when the user is behind the charges and has no access right to the site, the mobile phone cannot obtain the RSS feed. However, when the RSS feed is automatically acquired periodically as described above, the WEB server cannot temporarily process the RSS feed acquisition request from the mobile phone because the WEB server side temporarily goes down. Regardless of the state, an RSS feed acquisition request is mechanically transmitted to the WEB server. For this reason, there has been a problem that unnecessary communication costs are incurred.

  In addition, for example, when the contractor has stopped the RSS service for the user because the user is delinquent to the content provider, the WEB indicating that the service cannot be used is used. Send the page to the user's mobile phone. This WEB page is not an RSS Content-Type but an ordinary HTML Content-Type. In such a case, the summary information (RSS feed) is not transmitted even though the WEB server performs normal processing. Even in this case, if the RSS feed is set to be automatically acquired periodically, the RSS is periodically sent to the WEB server even though the mobile phone cannot acquire the RSS feed. A feed acquisition request is transmitted, and there is a problem in that unnecessary communication costs are incurred as described above.

  SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and the object of the present invention is to periodically send a summary information acquisition request to the server, even though the summary information cannot be acquired. It is an object of the present invention to provide a mobile communication terminal that can prevent the occurrence of the problem.

In order to achieve the above object, the invention according to claim 1 is characterized in that a display unit for displaying an image, a communication unit for communicating via a communication network, and a server for obtaining content summary information are periodically requested. The mobile communication terminal that displays the acquired summary information, and received an acquisition response from the server indicating that the process for the acquisition request could not be processed normally. In this case, the acquisition unit temporarily stops the periodic acquisition of the summary information.
The invention of claim 2 is the mobile communication terminal according to claim 1, wherein when the summary information acquisition request is transmitted to the server, the content-type different from the content-type of the summary information is transmitted from the server. When receiving Type data, the acquisition means temporarily stops the periodic acquisition of the summary information.
The invention according to claim 3 is the mobile communication terminal according to claim 1 or 2, wherein the summary information acquisition request is transmitted to the server by manual operation while the periodic acquisition of the summary information is suspended. When the acquisition response is information indicating that the processing for the acquisition request has been successfully processed, and the Content-Type of the data received from the server is the Content-Type of the summary information, the acquisition means The temporary acquisition of the summary information is canceled.
According to a fourth aspect of the present invention, the summarization information acquisition request is periodically transmitted to a display means for displaying an image, a communication means for communicating via a communication network, and a server on the communication network, and the summarization is performed. In the mobile communication terminal for displaying the acquired summary information, when the acquisition request for the summary information is transmitted to the server, the Content-Type of the summary information is transmitted from the server. When the content-type data different from the above is received, the acquisition means pauses the periodic acquisition of the summary information.
The invention according to claim 5 is the mobile communication terminal according to any one of claims 1 to 4, wherein the summary information is heading information, summary information, and update information of WEB content. Is.

  According to the first to third and fifth aspects of the invention, the acquisition request transmitted by the server when the server side is temporarily down, or the user refuses the acquisition request of summary information due to unpaid fees, etc. When the acquisition response indicating that the processing for the above could not be processed normally is received, the periodic acquisition of the summary information is temporarily stopped. As a result, when the server side temporarily goes down or the server side rejects the summary information acquisition request and the summary information cannot be acquired, the summary information is periodically acquired from the server. It is possible to prevent the request from being transmitted. Thereby, it can suppress that a user bears a useless communication expense.

  Further, according to the inventions of claims 4 and 5, the content provider stops the service for the user, and “use by the data of a format different from the format of the summary information (for example, HTML (Hyper Text Markup Language)” is used. WEB page data stating that it is not possible) is transmitted, the periodic acquisition of summary information can be suspended. Therefore, when the content provider stops the summary information provision service for the user and cannot obtain the summary information, a summary information acquisition request is periodically sent to the server. Can be prevented. Thereby, it can suppress that a user bears a useless communication expense.

FIG. 8 is a diagram illustrating a control flow during the RSS feed acquisition process of the mobile phone 10.
First, the mobile phone 10 accesses the WEB server 41 on the communication network based on a URI (Uniform Resource Identifier), and transmits an HTTP request (S1). When the mobile phone receives an HTTP response to the HTTP request from the WEB server 41 (YES in S2), it is checked whether the HTTP status code is 200 (S3). When the HTTP status code is 200, that is, when the WEB server 41 correctly processes the HTTP request and correctly transmits the requested WEB page, the mobile phone is described in the header of the HTTP response next. Content-Type data is checked to determine whether it is RSS (S4). If it is RSS (YES in S4), the process is terminated as it is. On the other hand, if it is not RSS, it is checked whether or not it is an automatic acquisition process (S6). If it is an automatic acquisition process (YES in S6), the automatic acquisition process is temporarily stopped (S7). At this time, as shown in FIG. 7B, for example, a “paused” pictographic image as shown in the figure is displayed in the pictogram area of the screen corresponding to the RSS feed that has been paused. Inform.
Also, if the received HTTP response includes an HTTP status code in the 400s indicating a client error or an HTTP status code in the 500s indicating a server error (YES in S5), the automatic acquisition process is performed as described above. It is checked whether or not (S6), and in the case of automatic acquisition processing (YES in S6), the automatic acquisition processing is temporarily stopped (S7).

  If the manual acquisition process is performed and the normal process (the status code of the received HTTP response is 200 and the Content-Type is RSS), the automatic acquisition process is canceled and the automatic acquisition process is performed again. Let it resume. At this time, the “temporarily stopped” pictogram image displayed in the pictogram area is turned off.

  As described above, according to the present embodiment, when the mobile phone 10 receives the HTTP status code of the 400 series client error or the 500 series server error, the automatic acquisition process is temporarily stopped. As a result, when the HTTP request has an incorrect syntax, or when the server cannot return a response to the HTTP request, the summary information (RSS feed) cannot be received. No summary information acquisition request is sent to 41. As a result, useless acquisition requests are not transmitted and useless communication costs are not incurred. Moreover, the load on the mobile phone communication network 20 can be reduced by eliminating such useless communication.

  Even when the request transmitted from the mobile phone 10 is normally received by the WEB server 41 and the HTTP status code: 200 indicating that normal processing is performed based on the request in the WEB server, the Content- When Type is not RSS, the automatic acquisition process is temporarily stopped. This is because, for example, if the service provider for the user is suspended for the reason that the user is delinquent to the content provider, the WEB indicating that the service cannot be used. The page may be transmitted to the user's mobile phone 10. This WEB page is not an RSS Content-Type but an ordinary HTML Content-Type. In such a case, although the WEB server 41 is performing normal processing, summary information (RSS feed) is not transmitted. Therefore, even when the content provider does not transmit the RSS feed to the user, the summary acquisition request is repeatedly transmitted to the WEB server 41 by pausing the automatic acquisition process. Disappears. As a result, useless acquisition requests are not transmitted and useless communication costs are not incurred. Moreover, the load on the mobile phone communication network 20 can be reduced by eliminating such useless communication.

  Also, for example, when the requested site is no longer available on the server, and the HTTP status code 410 (Gone) in a state where the transfer destination address is not known is received, the connection destination (URI) There is no possibility of receiving summary information even if accessed again. Therefore, when the mobile phone 10 receives such an HTTP status code, it is meaningless to store the RSS feed in the mobile phone 10. Therefore, when the mobile phone 10 receives such an HTTP status code, a deletion process for deleting the RSS feed stored in the mobile phone 10 may be performed.

  Further, the present invention is not limited to a mobile phone and can be applied to various mobile communication terminals provided with a display means. That is, as the “mobile communication terminal” in the present invention, a PDC (Personal Digital Cellular) system, a GSM (Global System for Mobile Communication) system, a TIA (Telecommunications Industry Association) system mobile phone, an IMT (International Mobile Telecommunications) system, etc. -2000 standard mobile phone, TD-SCDMA (MC: Multi Carrier) mobile phone, one of TD-SCDMA (Time Division Synchronous Code Division Multiple Access), PHS (Personal Handyphone System), automobile phone And a telephone having a call function such as a fixed telephone. Examples of the “mobile communication terminal” include a communication terminal such as a PDA (Personal Digital Assistance) having a call function in addition to the above telephone.
