Description

Method for browsing network information with handheld communication device

technical field

The invention relates to a method for browsing network information with a hand-held communication device, especially a method for customizing the webpage to be browsed so as to be easily viewed in a limited display area of the hand-held communication device.

Background technique

With the vigorous development of the Internet at present, it has become an indispensable application for personal computers, notebook computers, PDAs, etc. to connect to the Internet through the Internet. Information. However, the information content provided on the Internet and the layout design on the webpage are all designed for the browsing environment of the existing personal computer, so the hardware architecture of the personal computer is considered in terms of design and technology. Under such considerations, it is assumed that the user's personal computer is configured with a desktop, high-resolution display screen (greater than 800×600pixels), a processor with extremely strong computing power (greater than 1GHz CPU clock) and more Adequate network bandwidth (ADSL/Fiber connection), use this screen to view web pages through a web browser.

On the other hand, because the penetration rate of handheld communication devices such as mobile phones and personal digital assistants (PDA) etc. is gradually increasing and has diversified functions, one of which is to use handheld communication devices to perform Internet operations, but handheld communication devices must have Portability, so screen size, screen resolution, power consumption, battery life, memory capacity, processor computing power, Internet connection speed, and even mobile Internet network transmission costs, etc., have a huge difference compared with the operating environment of personal computers. The difference is that when surfing the web on mobile phones, PDAs and other devices, it is often not as smooth as using a personal computer. Therefore, users who currently use handheld communication devices to surf the Internet generally have unpleasant experience. Common problems include slow viewing speed, small screens that require constant scrolling, and even the language used to write web pages. (ActiveX/Java Applet/JavaScript) prevent normal browsing on handheld communication devices at all.

In order to adapt to the booming Internet-enabled handheld communication devices, web content providers also provide some solutions. For example, RSS (Really Simple Syndication) technology uses a simplified file encoding format to reduce the data transmission flow and the computing power required by the browser. However, this type of solution often needs to further re-adjust the webpage format specifically for the handheld communication device, and for the absolute majority of webpage content, it cannot effectively solve the problem of browsing by the handheld communication device. Therefore, with RSS, as shown in Figure 11, this technology can only provide the title link (title link) and its outline (abstract) of the webpage. When the user wants to watch the detailed content further carefully, he must click a hyperlink (hyper-link). As shown in Fig. 12, after clicking on the hyperlink, it is still linked to the original and complex webpage for ordinary personal computers to browse. Most web content providers don't even consider the browsing needs of handheld communication devices, so they don't provide RSS service on their web pages at all, which is completely unsuitable for handheld communication devices to browse.

Except having operating systems such as Microsoft Windows, Apple MAC in general personal computer, also install a browser (web browser), so-called browser is a kind of application software, common kind has Internet Explorer, Firefox etc. The browser is mainly used to interpret the web page data transmitted from a remote website into a human readable and recognizable display format, such as text, pictures, images, music, etc., while personal computers The webpage data received by the terminal is a binary data stream (binary data stream) composed of digital encoding technology before being interpreted. In addition to sending information from the remote website to the user's personal computer, many applications still need to output data from the client to the remote website to obtain two-way interaction, which will occur in querying, filtering, and authenticating users.

In order to package the text, pictures, video, music and other content of the aforementioned web pages and provide user interactivity, the industry has formulated a set of standard communication protocols, that is, HyperText Markup Language (HTML), which is a web page compilation language. language (makeup language for webpages). Please refer to Figure 13. Through the encoding process of HTML, the website can package all text, pictures, videos, music, and even program codes such as JavaScript before sending them to the user's computer. The browser, after the browser unpacks these, restores the original content and presents it to the user.

Since HTML supports diverse designs, it is quite easy to embed text, pictures, images, music, etc. in various formats into the same web page. In this way, for most current webpages, a large amount of multimedia data and embedded JavaScript are mixed in the picture returned by the same URL. This will not cause trouble for the browsers in the personal computers of ordinary users, and because the webpage provider has already optimized the environment for using the personal computer in advance when designing the webpage, so diverse webpage designs, Based on the original single file, various texts, charts, sounds, images, interactive JavaScript, and even Flash Player and other plug-in objects are subsequently added, allowing users to have a richer experience and attracting users to continue browsing and clicking on the website. other content of the .

Among the currently known technologies, some Internet Service Providers (ISPs) provide proxy gateways (proxygateways), which use the design method of translators (translators) to combine a complex component specially designed for personal computer browsing. Web pages, through the translation process, filter out grammars that cannot be browsed by ordinary handheld communication devices, and then forward them to the handheld communication device. This kind of design solves the problem that some webpages cannot be viewed by handheld communication devices to a certain extent. However, it only solves the compatibility problem of browsing on software and hardware. After the steps of translation and deletion, the remaining information is often meaningless. Doesn't help users get what they actually want to watch. In fact, when a user wants to browse a certain webpage, the starting point is to obtain the content that is meaningful to him. If the final display result is not what he wants, this kind of technology will not provide any real help.

Contents of the invention

In view of the aforementioned shortcomings of connecting to the Internet, the purpose of the present invention is to provide a method for browsing network information with a handheld communication device. By pre-designating the target information on a web page, the handheld communication device can directly view the information required by the user, and eliminate the need for web pages. Unnecessary advertisements and other non-interesting content on the website.

In order to achieve the aforementioned object, the method of the present invention includes the following steps: pre-establishing extraction rules in a web page extraction server, the extraction rules at least include the URL of a target web page and the target information to be extracted;

The webpage extraction server accepts a connection request sent by a handheld communication device, and the connection request includes an instruction specifying an extraction rule;

The web page extraction server queries a target web page through the Internet according to the aforementioned connection request, and extracts, filters and reassembles the content of the target web page according to the commanded extraction rules;

The web page extraction server replies the target information obtained after extraction and filtering to the handheld communication device for direct display by the handheld communication device.

Wherein, the extraction rules may define the URL of the original target web page, objects to be extracted, filtering rules, conversion rules and recoding rules, etc.

The beneficial effect of the present invention is that through the aforementioned steps, the user can customize the webpage content he is interested in and display it on a handheld communication device, and the user does not need to pre-install any program in his personal computer or handheld communication device. By using the retrieval function of the webpage extraction server, the extraction rules of the personal webpage can be customized, and the real-time data on the target webpage can also be obtained synchronously every time you watch online.

A client host 30 is connected to the aforementioned webpage extraction server 20 through the Internet, so as to set up and edit a plurality of different custom-made extraction rules 26 on the webpage extraction server 20, and each extraction rule 26 can define the original target webpage, desired extraction Objects, filter rules, conversion rules, re-encoding rules, etc., can extract the target information (content of interest) from one of the corresponding original target web pages in the web server 10, rather than the entire information content in the web page, wherein the client Host 30 can be a general personal computer;

A handheld communication device 40 is a communication device with display screen, operation interface and Internet access capability, such as mobile phone or personal digital assistant (PDA). The operation interface can include but not limited to keyboard, touch screen and buttons, Internet connection function Including but not limited to Dialup, WLAN, GPRS and 3G, etc., can be connected to the aforementioned webpage extraction server 20 and use the pre-established extraction rules 26 to connect to the webpage server 10 to view the target information.

Please refer further to FIG. 2 . In order to explain the specific technology of the present invention in more detail, a flow chart is supplemented for illustration. The method for browsing network information with a handheld communication device 40 in the present invention mainly includes two stages. The first stage is to establish and extract Rule 26, the second stage is to browse webpage information with the handheld communication device 40, and the steps of establishing the extraction rule 26 stage are described below.

Connect to the webpage extraction server 201, please refer to as shown in Figure 3, the user connects to the webpage extraction server 20 via the Internet through the client host 30, and uses the personal account number 21 and password 22 that have been registered in advance to log in to the webpage extraction server 20, if If the same user has logged in before, they can also directly enter the logged in screen through the cookie record method.

Designate a target URL to the webpage capture server 202. Please refer to FIG. 4. After the user successfully logs into the webpage capture server 20, the webpage capture function 23 (Capture from Web Pages) provided by the webpage capture server 20 can be executed. After executing this function, first input the website address (web address) of the target website, the webpage extraction server 20 will first grab all the information of the webpage corresponding to this website address, and send it back to the client host 30, and use The graphical interface (GUI) presents to the user all the objects of the current webpage.

Locking target information 203, assuming that the target URL specified by the user is http://finance.yahoo.com/, after receiving this request, the webpage extraction server 20 will automatically connect to the webpage represented by the URL, and send the webpage All objects are retrieved for analysis, and the analyzed results are sent back to the client host 30 for display. During this process, the webpage extraction server 20 has automatically pre-analyzed the components of the entire target webpage, and numbered each object. Please refer to FIG. 5A and FIG. 5B, when the user uses the mouse to move to any selectable object , a selection frame 24 will be automatically displayed, and the selection frame 24 can be represented by a thick red solid line frame on the screen; for example, in the lower part of Fig. , a selection frame 24 will automatically appear in the line graph object, indicating that the object can be selected; similarly, as shown in the lower part of Figure 5B, when the cursor of the mouse moves to other objects, such as a news block, the A marquee 24 will automatically appear in the news block. After confirming the selected object, the client host 30 sends an instruction to the web page extraction server 20, and the selected object is locked as target information. 40 target information for online viewing.

Preview the selected target information 204, as shown in the upper left corner of Figure 5B. After the object is selected, a preview area 25 can be displayed on the page of this custom function for the user to confirm. If the preview content is confirmed to be correct, This setting operation can be named, and a pair of extraction rules 26 for the target information contained in the target URL can be established accordingly, as shown in FIG. 6 , that is, multiple extraction rules have been established on the web page extraction server 20. 26. Each extraction rule 26 can arbitrarily specify a graphic.

After the extraction rule 26 is established, the user can use the handheld communication device 40 to view webpage information. The second stage includes the following steps:

Log in web page extraction server 205, as shown in Figure 7, send a connection request with handheld communication device 40, this connection request is a request that conforms to communication protocols such as HTTP or HTTPS, thereby connects to this web page extraction server 20, and in a Enter the user's correct personal account number 21 and password 22 on the login page, or use cookies to directly enter the login state.

Specify the extraction rules 206, as shown in FIG. 8 , when the web page extraction server 20 confirms that the hand-held communication device 40 has successfully completed the login operation, it can enter the user's personal operating environment in the web page extraction server 20. In this operating environment, The customized extraction rule 26 established in the previous stage is displayed, and an extraction rule 26 to be linked can be selected through the handheld communication device 40; please refer to FIG. 9 . In addition to pre-establishing the extraction rules 26 by the user, the web page extraction server 20 can also provide additional public extraction rules 26A for more commonly used information, web pages, etc. pre-designed extraction rules 26, such as weather, road conditions, news and stock markets, etc. , providing a more convenient and fast online shortcut for users to directly click.

Display target information 207, as shown in Figure 10, whether it is a custom extraction rule 26 or a public extraction rule 26A created by the user himself, when the selection is completed, the web page extraction server 20 will extract the information according to the extraction rule 26 (26A) The website is connected to the webpage server 10, so that the user's handheld communication device 40 can only see the pre-locked target information. In this embodiment, the line-type object is used as an example. In this way, it can be filtered out in the same webpage. Other unnecessary redundant data ensures that the object of interest can be viewed conveniently on the small display screen of the handheld communication device 40 .

The above steps are the implementation example and process of the present invention. Furthermore, the above-mentioned step of locking the target information 203 can be implemented in the following way in program implementation. For example, if the writing language of the target webpage is HTML, after the webpage extraction server 20 retrieves the webpage, it first parses out all embedded objects in the original webpage through an HTML syntax analyzer. After this step, a list of all constituent objects can be obtained, and then each object is numbered and recorded sequentially. Afterwards, according to the characteristics and selectability of the objects, a new screen written by JavaScript is recreated according to the layout of the original screen, and the objects in the list generated in the previous steps are sequentially added to the new layout, as shown in Figure 5A and Figure 5. 5B. In the process of adding a new screen, add the screen coordinate range setting for each selectable object. When the mouse moves within the range, the selectable frame 24 will appear, and the number of the object can be recorded and sent back to the web page when clicking The program logic of the extraction server 20 is extracted.

When the user clicks on an object, the number of the object will be sent back to the web page extraction server 20 . Since the object number has previously linked the original webpage login process, webpage operation process, webpage information, demand objects, etc. related information in the previously established object list, the webpage extraction server 20 can create a special storage object according to all relevant information. The process required for obtaining the object, and the steps required for subsequent filtering and extracting the object after accessing the original web page. Finally, this set of process can be saved in the extraction rule 26 named by the user, so that the extraction rule 26 can be re-executed next time, and then the real-time update information of the object can be obtained. The above description is only one of the possible implementation methods, and there are many possibilities to achieve the equivalent program logic of the above process in practice.

The present invention utilizes several pre-designed or customized extraction rules 26 and a web page extraction server 20 to provide filtered information, so that handheld communication devices 40 such as mobile phones and PDAs can use their display screens to view the required information. In general, compared with the existing online method, the present invention has the following advantages:

1. Using the customization method of the present invention, the client does not need to pre-install any program in its personal computer or handheld mobile device. Instead, through the retrieval function of the webpage extraction server 20, the extraction rules 26 of personal webpages can be customized. In this way, compatibility problems caused by using different hardware and software can be avoided, and at the same time, the complexity of operations can be minimized for the client.

2. Through the method of customizing personal webpages of the present invention, each user can conveniently create his own personal extraction rules 26 without writing a program by himself, so as to realize the automatic translation of webpage content.

3. The webpage extraction server 20 has pre-parsed and numbered and listed each object in the original target webpage during the process of the user ordering the personal webpage. When the user customizes the extraction rule 26, the selected object will be recorded with its specific number code, so when the target information is displayed through the handheld device, the web page extraction server 20 will re-grab the latest real-time content according to the object number. Therefore, the extraction rule 26 is not limited to the deletion and reformatting of the original target webpage in the old technology, but the analysis, filtering, extraction of the latest content, reorganization, and arrangement of the overall webpage composition object. This innovative method can also obtain the latest information for web pages that change from time to time, such as news and real-time quotations.

4. The client terminal can effectively use the time for surfing the Internet with the handheld communication device 40. Since the user can first use the personal computer to edit and establish the online information that meets his own needs, he will immediately enter the target information after using a handheld communication device 40 to surf the Internet. The location effectively saves the cumbersome operation process of users entering webpages layer by layer, moving webpage screens, executing links and waiting for webpage conversion, which not only effectively reduces redundant operation time, but also greatly reduces users' online costs.

5. Due to the very large differences in display specifications, computing power, input methods, and connection speeds of various handheld devices, it is extremely difficult to browse webpages originally programmed for personal computers in the current Internet environment. However, after the process of customizing personal web pages according to the present invention, significant improvements in browsing readability can be obtained, and the final displayed results can also satisfy the different handheld devices used by each person, and obtain information that each person prefers differently. .

To sum up, the present invention is a very novel and significantly improved invention, which meets the requirements for patent application, so the application is filed in accordance with the law. .
