DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wireless hyperpage system for accessing and displaying a hypertext page.

[0002]

2. Description of the Related Art In recent years, the development of portable information terminals with a wireless communication function (hereinafter abbreviated as wireless portable terminals) has been activated.

[0003] Data transmitted by wireless communication handled by these terminals includes not only texts and images but also hypertext pages in which multimedia information is mixed.

[0004] The hypertext page is World
A mixture of still images, moving images, audio, texts, agents, and the like, as typified by a Wide Wed homepage, is widely known.

In a conventional hypertext page, information can be easily navigated by displaying a link destination page by a user's selection.
Application to intranets widely used by companies,
The importance of the hyper page system is growing.

[0006]

However, in the conventional technology, a server that holds a hypertext page may take an access history for the purpose of counting the frequency of access to the page. In order to make the user aware of the information, it is difficult to apply it to improve the convenience of a system such as "display on a wireless portable terminal".

On the other hand, a server that does not take an access history has a problem in improving convenience because there is no structural means for allowing a user to recognize access to a linked page.

In addition, in a hypermedia system disclosed in Japanese Patent Application Laid-Open No. 6-251082, in which the appearance of a new link node is reflected on a display and cannot be recognized by a user, reflection of an access history is not considered. Have similar problems in that respect.

In the prior art, the linked page can be displayed on the assumption that the linked page actually exists and that the access can be accepted.

For example, if the link is temporarily broken or the access is concentrated on the linked page, the linked page may not be displayed. The user cannot recognize whether the access is merely concentration or the link is broken.

Since the user does not recognize the state of the page to which the link is linked, a useless access is generated, and the connection may be more difficult.

[0012] Therefore, even if the linked page is inaccessible, there is no system configuration problem that there is no means for the user to recognize in advance that the page is inaccessible, and limited wireless resource utilization efficiency. There was a problem of decline.

[0013] Also, in the hypermedia system of the cited example, if there is an inaccessible link, there is a similar problem.

[0014]

According to a first aspect of the present invention, there is provided a hyper page system, comprising: a hypertext page containing data of an arbitrary medium holding a plurality of links between pages having a network structure; Means for displaying the page holding the link node, outputting the linked page to the display terminal by selecting the link node, and displaying the page on the display terminal. A hyper page system comprising: a link destination page status display unit that displays access information in a form different from a page displayed according to access friction.

According to a second aspect of the present invention, in the hyper page system, when the page status display means cannot access the linked page due to friction caused by the access to the linked page, the page is not accessible. 2. The hyper page system according to claim 1, wherein the information is additionally displayed.

According to a third aspect of the present invention, there is provided a recording medium on which a program for a hyper page system is recorded, wherein a hypertext page containing data of an arbitrary medium holding a plurality of links between pages having a network structure is selected by a user. A page display is performed on a page display terminal, a page holding a link node is displayed, and a link destination page is output to a display terminal by selecting a link node, and access to the link destination page is performed. A recording medium recording a program of a hyper page system, wherein access information is displayed in a form different from a page displayed according to friction.

First, the link page server 8 accesses the page database 6 after receiving the page transmission request of the address Adr requested from the wireless portable terminal 12 (step 100).

In the prior art, the process directly shifts to page transmission. Next, the present invention waits for an access response (step 102). If no response is returned and no timeout occurs (step 103), It is determined whether the wireless line has been disconnected (step 104).

If the line has been disconnected, the server processing is interrupted.

When a timeout occurs, the BU
Since it is in the SY state, the access information Condi
is set to “BUSY” (step 10
5).

Also, there is an access response, and
If the page exists (step 106), access information Condition "OK" is set (step 108).

If there is a response to the access but the page at the address Adr does not exist, the access information Condition is set to "NOT FOUND" (step 107).

Next, the access information is stored in the access history memory section 5 of the link server 8 as an access history file. The stored contents are an address Adr, access information C
The condition and the current time t are added to the access history file (step 109).

Next, if the access information is OK (step 110), a file search for the address of the link of the hypertext page at the address Adr is performed (step 111).

Thus, the number of links and the address are obtained.
The access module is called the number of times corresponding to the number of links (steps 112 to 115).

Thereafter, the page of the address Adr is transmitted (step 116), and the access information array SEARC is transmitted.
h (1, 2,..., Lnum) are subsequently transmitted (step 117).

FIG. 5 is a flowchart showing the algorithm of the operation of the access information processing module in FIG.

First, the access history file of the hypertext page of Laddr (Loop) is referred to (step 201), and the access information Condition within tT from the latest time t is extracted (step 20).
2).

If they are all "OK",
If the condition is the same (step 20
3), assign the Condition value at the latest time t to the access information array Search (Loop) (step 205), and end the processing. By the way, the extracted access information is different, and "NOT FOU
If "ND" is included (step 204), "NOT"
It is determined whether the access information has changed from "FOUND" to "OK" (step 205).

If it has changed, the access information array Sea
Substitute “OK” for rch (Loop) (Step 2
07) If not changed, “NOT FOUND”
Is substituted (step 206).

On the other hand, if "NOT FOUND" is not included, it is determined whether the access information has changed from "BUSY" to "OK" (step 208).

If it has changed, the access information array Sea
“OK” is substituted for rch (Loop) (Step 20)
7) If it has not changed, "BUSY" is substituted (step 209).

Finally, in the embodiment, since "OK" is not displayed, the value of "OK" in the access information array is overwritten with a null symbol (steps 210 to 211).

FIG. 6 is a flowchart showing the algorithm of the operation from the transmission request of the page display to the reception and display in the wireless portable terminal 12.

First, a page transmission request of the address Adr is transmitted by operating the input section of the terminal (step 30).
1).

Next, when the processing is interrupted on the server side (step 302), the processing on the terminal side is interrupted.

On the other hand, when the processing on the server side is completed, a hypertext page is received (step 303), and subsequently, access information is received (step 304).

Next, a file search for the number of links and the display position in the received hypertext page is performed (step 305), and the hypertext page is displayed (step 306).

After the display, all the access information is displayed (steps 307 to 310), and the processing on the terminal side ends. The algorithm for the operation of step 305 is shown in FIG.

FIG. 7 is a flowchart showing an algorithm of an operation for performing a file search for the link of the hypertext page at the address Adr and calculating the number of links, the address, and the display position.

First, Lnum that holds the number of links is initialized (step 401), and a search for a link in the hypertext page at the address Adr is performed.

When the search is completed to the end (step 403)
And when a link cannot be found (step 40)
4) ends the processing. If a link is found, L
num is incremented and the address of the found link is recorded in Laddr (Lnum) (step 40).
5, step 407).

To determine the display position, the value obtained by adding the number of characters +1 to the display position X of the link node is set as the X coordinate, and the display position Y of the link node is set as the Y coordinate (step 406).

FIG. 8 is a flowchart showing the algorithm of the operation of recording data in the access history file in step 109 in FIG.

First, the corresponding file name is searched by the file search table shown in FIG. 10 (step 50).
1).

If the file name does not exist (step 502), the new file name is recorded in the file search table and an access history file is generated in the access history memory unit (step 503).

Next, the address Ad is assigned to the file.
r (21a), address information Condition
(21d) The current time t (21c) is recorded, and the process ends (step 504).

FIG. 9 shows an embodiment of an access history file recorded in the access history memory unit 5.
