JP2001043123A - Radio communication terminal and read/retrieval method - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a radio communication terminal with which a home page can be read even out of the range by acquiring and displaying the desired home page from a cache when there is the home page in the cache or from the Internet through a radio communication part when there is no desired home page in the cache. SOLUTION: A user inputs a URL from an input means 101. This URL is sent to a browser 103. Then, the browser 103 judges whether the cache function of a cache 104 is effective. When the cache function is effective, it is displayed on a display part 106. When not, the home page is acquired by communicating with the Internet 107 through a radio communication part 102. The acquired home page is stored in the cache 104. Thus, even when he user invalidates the cache function of the browser 103, the user refers to the home page in the cache 104 as long as a radio communication terminal 100 is located out of the range.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wireless communication terminal and a browsing / searching method, and more particularly to a WWW (Worn) for the Internet.
1. Field of the Invention The present invention relates to a wireless communication terminal having a browser function and a browsing / searching method having a browser function as browsing / searching software for an ld Wide Web.

[0002]

2. Description of the Related Art Wireless communication terminals mainly using the Internet and mobile phones have become widespread. As a general technique for viewing an Internet homepage, for example,
Japanese Unexamined Patent Publication No. 322478 discloses a "hypertext access device by voice" which includes a mobile terminal having a telephone function and a WWW.
It discloses a technique for minimizing the required memory when implementing a browser and effectively receiving WWW information on a small screen at low communication cost. Further, Japanese Unexamined Patent Publication No.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration and operation of a preferred embodiment of a wireless communication terminal with a browser function and a browsing / retrieval method according to the present invention will be described below in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram showing the configuration of a preferred embodiment of a wireless communication terminal with a browser function (hereinafter simply referred to as a wireless communication terminal) of the present invention. The wireless communication terminal 100 includes an input unit 101, a wireless communication unit 102,
It comprises a browser 103, a cache 104, an in-service / out-of-service determination unit 105, and a display unit 106. The wireless communication terminal 100 is configured to be connected to the Internet 107 via wireless communication in a wireless communication unit 102.

The browser 103 can access the Internet 107 via the wireless communication unit 102 to obtain a home page. The cache 104 stores the homepage acquired by the browser 103. The cache function can be set to valid / invalid. The input unit 101 allows the user to input a URL (Uniform Resource Locator).
Used to enter into. Out of service / out of service display unit 105
Determines whether the wireless communication terminal 100 is in the service area or outside the service area. The display unit 106 displays the contents of the home page so that the user can read it.

The specific and detailed operation of the wireless communication terminal 100 of FIG. 1 will be described later with reference to the flowchart of FIG. 2, but the general operation will be described below. First, the user inputs a URL from the input unit 101. This URL is sent to the browser 103. Therefore, the browser 103 determines whether the cache function of the cache 104 is valid or invalid. If the cache function is valid, it is displayed on the display unit 106. If the cache function is not valid, the Internet 1 via the wireless communication unit 102
07 and obtain a homepage. The acquired homepage is stored in the cache 104.

Next, a detailed operation of the wireless communication terminal 100 of FIG. 1 will be described with reference to a detailed flowchart of FIG.
First, in step 201, the user inputs a URL to the browser 103 using the input unit 101. Next, in step 202, the browser 103 checks whether the cache function of the cache 104 is valid or invalid.

If the cache function is valid (YES) in step 202, the flow advances to step 203 to check whether or not there is a homepage corresponding to the URL input by the user in the cache 104. If there is a corresponding homepage in the cache 104 (YES),
Proceeding to step 204, a home page is acquired from the cache 104. Then, in step 205, the acquired home page is displayed on the display unit 106.

If it is determined in step 203 that there is no corresponding homepage in the cache 104 (N
In step O), it is checked in step 206 whether the vehicle is within the service area. If it is within the service area (YES), the process proceeds to step 207, where the wireless communication unit 102 communicates with the Internet 107 to acquire a home page. Next, the process proceeds to step 208 to store the acquired homepage in the cache 104. Finally, the process proceeds to step 205, where the home page is displayed on the display unit 106. If the determination in step 206 is out of service area (NO), the process proceeds to step 214,
Acquisition of the homepage failed, and the operation ends.

Next, in the above-described determination in step 202,
If the cache function is invalid (NO), step 20
Go to 9 and check if you are within range. If it is within the service area (YES), the process proceeds to step 210 and the wireless communication unit 1
02 communicates with the Internet 107 to obtain a home page. Then, the homepage acquired in step 211 is stored in the cache 104. Further, the process proceeds to step 205, where the home page is displayed on the display unit 106.
To be displayed.

On the other hand, in the determination of step 209, out of service area (N
If the answer is O), the process proceeds to step 212, and the U input by the user from the input unit 101 into the cache 104.
Check if there is a homepage corresponding to the RL. If there is a homepage in the cache 104 (YES),
Proceeding to step 213, the home page is acquired from the cache 104. Further, the process proceeds to step 205, where the home page is displayed on the display unit 106. If it is determined in step 212 that there is no corresponding home page in the cache 104 (NO), step 21
Proceeding to 4, the acquisition of the homepage has failed, and the operation ends (END).

As described above, the browser 103 and the cache 104 are provided in the wireless communication terminal 100, and the step of determining whether the cache function is valid / invalid and the step of determining (or confirming) the communication area / out of service area are provided. Regardless, the homepage in the cache 104 is automatically browsed when the user is out of the service area.

The configuration and operation of the preferred embodiment of the wireless communication terminal with a browser function and the browsing / searching method according to the present invention have been described above in detail. However, the present invention should not be limited to only such specific examples, and those skilled in the art can easily understand that various modifications can be made without departing from the gist of the present invention.

[0028]

As can be understood from the above description, according to the wireless communication terminal with a browser function and the browsing / searching method of the present invention, the wireless communication terminal is out of the service area even if the user invalidates the cache function of the browser. In that case, refer to the homepage in the cache. Therefore, as far as the home page in the cache is concerned, it has a practically remarkable effect of enabling browsing. Of course, not in cache,
In the case of a local area, a desired homepage can be obtained by communicating with the Internet via a wireless communication unit.
