detailed description

The present invention will be further described in detail below with reference to the drawings and specific embodiments.

1 is a flow chart showing a webpage browsing method of a mobile terminal of the present invention. As shown in FIG. 1, the webpage browsing method of the mobile terminal provided by the present invention includes the following steps:

After the user submits the open webpage request (step S101) at the mobile terminal, the mobile terminal does not directly download the webpage directly, but first determines whether the cached data of the requested webpage exists in the local file system (step S102). If the cached data of the requested webpage exists in the local file system of the mobile terminal, the cached data of the requested webpage is directly extracted from the local file system of the mobile terminal, and then displayed on the mobile terminal according to the cached data. The requested webpage; otherwise, if the cached data of the requested webpage does not exist in the local file system of the mobile terminal, the mobile terminal acquires the original data of the requested webpage through networking (step S103), and acquires the acquired data. The web page raw data is analyzed (step S104), typeset (step S105), converted into result data composed of data types of different formats suitable for display by the mobile terminal; and then according to the knot The data is displayed on the mobile terminal to the requested webpage (step S106); and the result data is converted into a memory block, and finally the memory block is stored as cache data to a local cache of the mobile terminal, and the data structure of the cached data is suitable. Store and call processing locally on the mobile terminal. Here, as an example, the local file system may be a memory in the mobile terminal.

The implementation of the local cache mechanism of the present invention is based on a cache database that can be queried and utilized by the mobile terminal, and the mobile terminal converts the result data into a first data structure suitable for local storage and call processing of the mobile terminal. After entering the local file system of the mobile terminal, the local cache database of the mobile terminal is established or updated in real time, so that the webpage data can be directly extracted from the mobile terminal directly when the user browses the webpage again without downloading again.

The method for establishing local cache data for the browsed webpage shown in FIG. 1 enables the mobile terminal to fully utilize the idle time to cache the result data of the downloaded, analyzed, and typeset webpage to a local file system with a large storage capacity in the mobile terminal. Therefore, when browsing the webpage again, it is not necessary to re-run the time-consuming network downloading, analysis, and typesetting process, and only need to read the data in the local file system of the mobile terminal to directly display, thereby effectively saving the user's time. And traffic.

In the process of browsing the Internet by using a mobile terminal such as a mobile phone, due to the limitation of the hardware of the mobile terminal itself, a webpage that can normally be browsed on a normal PC browser cannot be normally displayed on the mobile terminal, and needs to be original on the mobile terminal. The webpage data is analyzed and re-formatted, and the result data suitable for display by the mobile terminal is generated before being browsed on the mobile terminal.

The result data here contains different structure data of all the controls (text, hyperlink, edit box, button, picture, etc.) of the webpage. The structure data of the control is composed of data types of different formats, usually including the download of the network. The original web page data is analyzed, the information position, height, width, and basic properties of the control are information. Since the data structure suitable for the result data displayed by the mobile terminal is not suitable for the storage of the local file system of the mobile terminal, in the present invention, in the process of writing the result data to the local file system of the mobile terminal, The result data needs to be converted into a first data structure suitable for local storage and call processing of the mobile terminal, and then stored locally in the mobile terminal. The specific process is: first converting the result data of all controls of the webpage into memory by means of memory block conversion. Block data, and then writing the converted memory block data to the local file system of the mobile terminal for caching; correspondingly, extracting the cached data of the required webpage from the local file system When the display is performed, the memory block data of the required web page is read from the local file system, and then the memory block data is converted into result data suitable for display by the mobile terminal for display.

Due to the variability of the data format, most of the data types need to be converted in the process of converting the result data of the web page control into the memory block data suitable for mass storage. Since any data can be converted to a binary format by shifting according to a certain rule, in a specific embodiment of the present invention, the conversion from the result data to the memory block data is mainly realized by the data shift conversion method. First, the result data of all the controls of the webpage is converted into a binary format by shifting according to the rules, and then the converted binary format data can be added to form a binary stream, which is a large file storage system suitable for the local file system. Memory block.

On how to compose the converted binary format data into a binary stream by appending, the following describes its implementation in C/C++:

Suppose char* buf is the final memory block and the space is large enough.

1, the integer n is converted to a binary stream, because the integer occupies four bytes

Int n;

Char Str[32];

Str[0] = n»24;

Str[l] = n»16;

Str[2] = n»8;

Str[3] = n»0;

Str[4] = '\0';

Strcat(buf, Str);

2, the string "abed" is converted to a binary stream

Char Str[32] = "abed";

Strcat(buf, Str);

That is to say, since the result data is composed of different structures, and the structure is composed of data types of different formats, in the conversion process, first, the structure of all the result data constituting a web page is All data types are converted into binary format, and then the binary data of the structure is added to the structure memory block. When all the structure data of the result data is converted into a memory block, the memory blocks are added together to realize the result data. Conversion to memory block data.

Correspondingly, in the process of extracting the cache data of the webpage from the local file system, the conversion manner of converting the memory block data stored in the local file system into the result data is opposite to the manner of converting the result data from the result data to the memory block data, first The whole memory block data representing the web page is decomposed into a single structure memory block, and then the structure memory block is separately decomposed into a binary format, and finally the binary format is inversely shifted into the data type required by the result data. Just fine.

In the present invention, the local file system of the mobile terminal refers to a mobile phone card stored in the mobile terminal (eg,

SIM card) or file system in a memory card (such as a SD card, CF card, etc.).

In addition, after the result data is written to the local file system of the mobile terminal, if the result is stored, it is possible to enable the mobile terminal to have more memory processing data of the front end, thereby improving the data processing capability of the mobile terminal.

In order to make full use of the storage space of the mobile terminal, in the present invention, the mobile terminal also uses the preset rules (such as the number of times the webpage is browsed within a prescribed time, the security level of the webpage, the content classification of the webpage, etc.) to the file system. The cached data is cleaned to delete the cached data of the webpage that is less likely to be used or reused for a long time, and to release the storage space of the file system, thereby improving the utilization of the storage space of the mobile terminal.

In order to effectively manage the cached data in the local file system of the mobile terminal, it is convenient to perform the search, extraction and timely cleaning of the cached data with low utilization during web browsing. In a preferred embodiment of the present invention, A dynamic cache record is also established in the local file system of the mobile terminal for dynamically recording information of the cached data in the local file system of the mobile terminal. Through the dynamic cache record, the mobile terminal can conveniently determine whether the cached data of the requested webpage exists in the local file system, cache data that needs to be extracted quickly, and timely and effectively manage the cached data according to the record information, thereby improving the movement. Utilization of terminal storage space. 2 is a block diagram showing the structure of a browser 10 in accordance with the present invention.

If the cached data of the requested webpage exists in the local file system of the mobile terminal, the cached data extracting unit 2 directly extracts the cached data of the requested webpage from the local file system of the mobile terminal for use in the browser of the mobile terminal. Displayed on.

If the cached data of the requested webpage does not exist in the local file system of the mobile terminal, the webpage original data acquisition and processing unit 3 obtains the original data of the requested webpage through networking, and analyzes the acquired raw data of the webpage, The typesetting is converted into result data suitable for display by the mobile terminal. Typically, the result data consists of data types in different formats.

In addition, the browser 10 may further include a cache data establishing unit 4, configured to convert the result data into memory block data having a first data structure suitable for local storage and call processing of the mobile terminal, and The memory block data is written as cache data into a local file system of the mobile terminal to establish cache data of the mobile terminal. In other embodiments of the present invention, as shown in the figure, the cache data establishing unit 4 may include a memory block generating unit 41 for generating memory block data based on the result data; and a writing unit 42 for using the The memory block data is written as cache data in the local file system of the mobile terminal to establish cache data of the mobile terminal.

Corresponding to the webpage browsing method of the mobile terminal, in an example of the present invention, the memory block generating unit 41 may further include a format conversion module (not shown) for using the result data by shifting by rules. Converting to a binary format; and a memory block data forming module (not shown) for appending the converted binary format data to a structured memory block in the form of a binary stream. Then, the writing unit 42 stores the memory block as cache data in the local file system of the mobile terminal to establish cache data of the mobile terminal. The result data includes structural data of all controls of the webpage, and the control structure data includes information about the original data of the webpage, information position, height, width, and basic property information of the control.

In addition, in a preferred implementation manner of the mobile terminal provided by the present invention, the number of caches is further included. According to the management unit (not shown), after the cache data establishing unit 4 converts the result data into a memory block and stores the data as cache data to the local file system of the mobile terminal, it is determined whether the result data is currently browsed. If not, delete the result data in the memory of the mobile terminal to release the memory. Moreover, the cache data management unit further cleans the cached data in the file system according to a preset rule to delete cache data that is not used for a long time, and release the storage space of the file system.

Further, the browser may further be provided with a cached data dynamic recording unit (not shown) for dynamically recording a dynamic cache record of information of the cached data in the local file system of the mobile terminal, so that the mobile terminal records the cache according to the dynamic cache.
