DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication network system using a web page created in, for example, a hypertext format, and more particularly, to a communication network system provided with a prefetch function that allows a user to quickly access desired information. It relates to a communication network system.

[0002]

2. Description of the Related Art In recent years, communication network systems using electric communication lines such as public telephone lines typified by the Internet and intranets have rapidly spread. In this communication network system, for example, a user uses a personal computer, a word processor, or the like as a connection terminal, and a data server provides predetermined information requested by the connection terminal to the user.

In a communication network system, a web page created in hypertext format (HTML) is stored in a storage device provided in each data server (web server), for example, a hard disk. Other web pages are associated with this web page together with various data such as text data, image data, and audio data. Then, the user can access desired information while following this link. At the time of information access, communication is performed from the user's connection terminal requesting predetermined data to the web server, and in response to this, the web server supplies predetermined data to the user's connection terminal. It has become. And
The data of the web page supplied from the web server is displayed on a display unit provided in the connection terminal and browsed.

[0004]

In a communication network system such as the Internet or an intranet, a public telephone line is mainly used, so that the data transfer rate is naturally limited. For this reason, when the user quickly displays various web pages or obtains desired data, it takes time from the designation of a desired web page or image to the display thereof. Therefore, many measures have been taken to solve such a problem.

As an example, there is a means for adding a function of prefetching web page data to a connection terminal (hereinafter, abbreviated as a prefetch function). This prefetch function is to read data of another web page linked to the currently viewed web page from the web server regardless of whether or not the user desires to view the web page, and to store the data in the storage device provided in the connection terminal. This data is stored in a memory (not shown). In general, reading data from a storage device, for example, a hard disk and displaying it on a display unit is shorter than displaying data on a display unit, compared to transferring data via a public telephone line. Specified web page,
By displaying the data of the web page stored in the storage device in advance on the display unit, the time from the designation to the display is reduced, and a browsing environment with less stress is provided.

[0006] However, in the connection terminal to which the prefetch function is added as described above, regardless of whether or not the user desires, other web pages mechanically linked to the link described in the page information of the web page. In this method, pages and image data are sequentially stored in a storage device. Therefore, when the user finds a link to another web page on which desired information is posted by looking at the description of the currently displayed web page, and selects this link,
Even if the user specifies this link, the data is not always stored in the storage device when the link is specified.

Therefore, when there is no corresponding web page data in the storage device provided in the connection terminal, the data of the other web page must be read from the web server via the public telephone line again. There is a problem that it is not possible to shorten the time required for the process. Such a problem occurs not only in the Internet but also in an intranet using a similar technique.

The present invention has been made to solve this problem, and has as its object to provide a communication network system having a function of preferentially prefetching data of a web page on which information desired by a user is published. Is to provide.

[0009]

In order to solve the above problem, a communication network system according to the present invention comprises a server storing a web page described in a hypertext format, and a web page transmitted from the server via a telecommunication line. In a communication network system including a connection terminal that reads a web page, a web page describes a link destination address for jumping to another web page, and the link destination address includes category data indicating the type of the other web page. When a web page is read by a connection terminal, category data is prioritized and another web page is prefetched.

The communication network system according to the present invention may further comprise: read priority data that determines the order in which linked web pages are read in accordance with the type of category data; and read count that summarizes the number of times category data is read by type. Data, and the read priority data is changed according to the number of times in the read count data.

Further, in the communication network system according to the present invention, when the category data is not included in the read count data, the category data is added to the read count data.
