Next, a procedure for generating a tree structure and a procedure for specifying a return destination using the tree structure in the communication terminal device of the present invention will be described with reference to the flowcharts of FIGS. First, a procedure for generating a tree structure will be described. Main control unit 1
Determines whether the user has instructed the displayed tree structure of the URL and link relation and instructed to open the page (step S1). When the user enters the "URL" of the page to be opened at the beginning of WWW browsing (step S
2), the main control unit 1 opens the page of the "URL" site input by the user (step S3).

Next, included in the opened page,
When the user instructs a “link” described by a keyword such as “here” by a click operation (step S4), the main control unit 1 accesses the URL of the link destination embedded in the “link” and sets the link. The page of the destination site is displayed (step S5). The main control unit 1 is “link”
It is determined whether or not the URL of the link source page in which is described is already stored in the RAM 7 as an access history (step S6). If the URL is already stored, the process proceeds to step S11.

On the other hand, if the result of determination in step S6 is that the URL is not yet stored in the RAM 7 as an access history, the main control unit 1 determines whether the number of stored URL information has reached the maximum value ( Step S7). If the maximum value has not been reached, "URL" is stored in the RAM 7 as URL information (step S9). When the Max value is reached, the oldest "UR
Release the area that stored "L" (step S
8) The link source “URL” is stored as URL information in the RAM 7 (step S9), and the link source “UR” stored in the RAM 7 is stored.
L ”is displayed at the position where the link source should be displayed in the tree structure (step S10).

After displaying the link source "URL" at the position to be displayed in the tree structure in this way, or after determining in step S6 that the link source "URL" is already stored in the RAM 7, It is determined whether or not the "link" (for example, a character string of the keyword) of the link destination is already stored in the RAM 7 as an access history (step S11). If the link is already stored, the process returns to step S1.

On the other hand, if the result of determination in step S11 is that the link has not yet been stored in the RAM 7 as an access history, the main control unit 1 determines whether the number of stored link information has reached the maximum value ( Step S12). If the maximum value has not been reached, the "link" is stored in the RAM 7 as link information (step S14). If the maximum value is reached,
After the area storing the oldest "link" is released (step S13), the "link" of the link destination is stored in the RAM 7 as link information (step S14), and the "link" stored in the RAM 7 is stored. Link "is displayed in connection with the URL of the link destination of this link in the tree structure (step S15
). The above steps S1 to S15 are displayed in the URL
And the tree structure of the link are instructed until the user is instructed to open the page.

FIG. 5 is a diagram for explaining a specific generation process of the tree structure. For example, when the user inputs the URL of “page 1”, as shown in the left half of FIG.
Site is displayed. Next, the user selects “page 1”
When "Link 1" is designated, the page of the site of "Link 1", that is, "Page 2" shown in the left half of FIG. 5 (b) is displayed, and at the right half of FIG. 5 (a). A tree structure as shown, that is, a tree structure in which, for example, a character string of a keyword of “link 1” as a link destination is linked to a URL of “page 1” as a link source. The tree structure is displayed by dividing the screen on which the page is displayed and juxtaposing the page (see FIG. 7A). The tree structure is reduced and displayed in a window opened on the screen on which the page is displayed (see FIG. 7B). When a tree structure is displayed in the window, the tree structure may be displayed by a user operation when necessary.

Similarly, when the user designates “link 4” of “page 2” shown in the left half of FIG.
The tree structure shown in the right half of (b), that is, the URL of “Page 1” as the link source is linked to the URL of “Page 2” as the link destination.
A tree structure is displayed in which a URL is linked, and furthermore, "Link 4" having this "Page 2" as a link source is linked to the URL of "Page 2".

While the tree structure is displayed as shown in FIG. 5 (b), the user inputs the URL of "page 1" or, as described later, uses the tree structure to change "page 1" or "page 1". When "Link 1" is designated, the site of "Page 1" is displayed as shown in the left half of FIG. 5 (c). Next, when the user instructs "link 2" of "page 1", a page of the site of "link 2", that is, "page 3" shown in the left half of FIG. The tree structure shown in the right half of FIG. 5 (c), that is, the “link 2” which is the current link destination is added to the URL of “page 1” as the link source to which “link 1” has already been linked. The linked tree structure is displayed.

Similarly, when the user designates "link 5" of "page 3" shown in the left half of FIG.
(d) The tree structure as shown in the right half, that is, the URL of “Page 1” as the link source and the UR of “Page 3” as the link destination
L, and a tree structure is displayed in which “link 5” with “page 3” as the link source is linked to the URL of “page 3”.

Next, a procedure for specifying a return destination using a tree structure will be described. When an instruction is given to open the page by instructing the displayed tree structure of the URL and the link (YES in step S1), the main control unit 1 prompts the user to enter the "URL" from the designated position in the tree structure. Is determined (step S16).

If the user does not indicate "URL", "link"
When the main control unit 1 determines that the instruction has been given, the main control unit 1 displays the position of the page where the "link" is described, for example, the character string of the keyword is described (step S17). Move to S4. That is, if the page describing the “link” cannot be displayed on one screen, the position where the “link” of the page is described is displayed without displaying the top position of the page. Meanwhile, step
As a result of the determination in S16, when it is determined that the user has designated "URL", the main control unit 1 displays the top position of the page of the site of the "URL" (step S18), and proceeds to step S4.
Move to.

FIG. 6 is a diagram showing a specific example of a return destination specification using a tree structure. For example, when the user instructs “link 2” having a tree structure as shown in the left half of FIG.
As shown in the right half of the page, the position where “Link 2” is described in “Page 1” where “Link 2” is described is displayed. When the user designates “link 4” in the tree structure as shown in the left half of FIG. 6B, “link 4” is described as shown in the right half of FIG. 6B. The position of “Page 2” where “Link 4” is described is displayed. Although the example of displaying the page from the beginning of the page is shown in the display of the page on the right side of FIG. 6, the designated link may be displayed at the head of the page and the subsequent link may be displayed.

When the user designates the "URL" of the tree-structured page 2 as shown in the left half of FIG.
As shown in the right half of (c), the top position of “Page 2” is displayed. When the return destination is specified using the tree structure, when the user specifies "link 2" as shown in the left half of FIG. 6D, the link destination of "link 2" is specified. It may be configured to display the head position of “page 3”.

The “URL” displayed as a tree structure is UR
It is not limited to L itself. For example, NetscapeNa
It could be something like the name of a bookmark in a vigator (a WWW browser from Netscape Communications, USA). Conversely, a “link” is not limited to a character string of a keyword, but may be a URL itself. Further, in the tree structure display of the link relation, information such as the URL of the currently displayed page may be displayed so as to be distinguished from other pages. For example, the “URL of page 2” in the tree structure display of FIG. 5 may be blinked or displayed in a different color from the others.
