TW515184B - Method for downloading big-size information using WAP - Google Patents

Abstract

The invention relates to a method for downloading big-size information using WAP that sets up a special web page program block (such as ASP) in a wireless electronic device (such as PDA) and server of a wireless network, allowing to issue a request for downloading big-size information to the server while the electronic device is utilizing the block format, the server reads the corresponding document from a database in accordance with the request contents, then divides the document into multiple information blocks in accordance with the data transmission limitation of the wireless network and responds to the electronic device with the block format for all of the information blocks, making the electronic device issue command to download each information block data one-by-one to the server and the server sequentially forward each information block of the document to the electronic device in accordance with such command. As such, the electronic device can combine those received information blocks as a complete document to achieve the limitation of WAP in downloading big-size information.

Description

515184 V. Description of the invention (1) Background of the invention: The present invention is a method for downloading large-scale data using a wireless communication protocol. When a server on a wireless network receives a request for downloading large-scale data from an electronic device of a client , The server reads the corresponding file from a database according to the content of the request, and then divides the file into a plurality of data blocks according to the limitation of the wireless network transmission data, and the total of these data blocks The number of blocks responds to the electronic device, so that the electronic device sends a command to download the data of each data block to the server one by one, so that the server sequentially transfers each data block of the file to the electronic device according to the commands, In addition, the electronic device can combine the received data blocks into a complete file, which breaks through the limitation that wireless communication protocols cannot download large-scale data. 4 Previous techniques: Press, wireless communication protocol (WAP) is a wireless communication environment A communication protocol that provides Internet services, allowing people to easily use mobile terminals (such as: mobile phones, digital (Personal assistants, etc.) to get real-time information on the wireless network (such as: real-time news, stock market quotes, etc.), instead of having to dial in to the Internet through a personal computer that was inconvenient to carry, or an expensive laptop. However, the wireless communication protocol is limited to the size of the data transmitted through the wireless network (Gate W ay), so that each download request can only obtain a few K (1 OOOBye) of data, and cannot obtain more information. , For downloading other large types of data, it is not possible.

Page 5 515184 V. Description of the invention (2) Outline of the invention: In view of this, in order to improve the shortcomings of the above wireless communication protocol that cannot download a large amount of data, the inventor finally developed and designed a utilization wireless technology of the present invention after long-term research and experiment. Communication protocol download method of large dataZero

An object of the present invention is to set a special webpage program module on an electronic device of a client and a server on a wireless network respectively. When the electronic device uses the module format to send a request for downloading large data to the server Server, the server reads the corresponding file from a database according to the content of the request, and then divides the file into a plurality of data blocks according to the restrictions on data transmission on the wireless network, and divides the data The total number of blocks responds to the electronic device in the module format, so that the electronic device sends a command to download the data of each data block to the server one by one, so that the server according to the commands one by one The sequence is transmitted to the electronic device, so that the electronic device can combine the received data blocks into a complete file, which breaks through the limitation that wireless communication protocols cannot download large data. Another object of the present invention is to set a download progress indicator program on the electronic device. When the electronic device receives each data block of the file transmitted by the server, the indicator is displayed on the display through the display device. It is displayed, and when a data block of the file is received, the indicator bar is lengthened by a unit length to remind the user of the download progress. • For the convenience of the review committee, the purpose, shape, and structure of the invention

Page 6 515184 V. Description of the invention (3) Features and effects, for further understanding and understanding, the following examples are given in conjunction with the illustrations, and are described in detail as follows: * Detailed description: The invention is a kind of "Using wireless communication protocol The method of downloading large data "is set on a client-side electronic device (such as a digital personal assistant, a mobile phone, etc.) and a server on a wireless network with a special web program module (such as: dynamic web technology (ASP)), when the electronic device uses the module format to send a download large data request to the server, the server reads the corresponding file from a database based on the content of the request, and then According to the limitation of wireless network data transmission, the file is divided into a plurality of data blocks, and the total number of data blocks is used to reply to the electronic device in the module format, so that the electronic device sends out one by one and can download various data. Command to block data to the server, so that the server sequentially transfers each data block of the file to the electronic device according to the commands, so that the The electronic device combines the received data blocks into a complete file, which is displayed on a display for users to browse. In the present invention, a download progress indication bar program is set on the electronic device. When the electronic device receives each data block transmitted by the server, the instruction bar is displayed through a display, and the received When a data block of the file is added, the unit length of the indicator is increased to remind the user of the download progress. In the present invention, when the electronic device downloads each data block of the file and the download is terminated, the downloaded data is stored in a memory.

Page 7 515184 V. Description of the invention (4) Progress and downloaded files, so that when the electronic device downloads the file next time, it can continue to download the undownloaded part of the starting data block In part, the user can choose to terminate the download during the download period, so that the electronic device can continue to download from the interruption when the electronic device is downloaded again. -RAj In the present invention, the electronic device can be selected according to the selected part, (1) Issue a download command of the data of each data block of the part to the server, so that the server sequentially transmits each data block of the selected download part to the electronic device according to the commands,俾 The user can select several segments of the file to download.
