File download method between multiple handhold equipments based on wireless communication

Abstract

The present invention relates to a method for the document download between a plurality of handheld devices based on wireless communication. The method comprises at least one central office terminal server is arranged, a data base is established and maintained in the central office terminal server, and the data base is used for recording the network addresses and the file lists of the handheld devices; after each client is inscribed successfully and connected with the server, the file list of each client is promptly uploaded to the server and inputted into the data base, and simultaneously file lists uploaded or inputted into the data base by the other clients on line inscribed are get; a local client selects the files desired to be downloaded from the data base of the server, and sends a download request to the server; after the server receives the download request, the server promptly returns the remote client information of the files under desired to be downloaded to the local client; the local client sends a request to the remote client and gets answers, a connection is established between the both clients, and the local client beings the download process; and the other steps. The present invention can realize the resource sharing download between handheld devices, which facilitates users.

Description

technical field [0001] The invention relates to digital information transmission technology, in particular to a file download method in a network based on wireless communication. Background technique [0002] With the rapid development of electronic technology, a variety of handheld devices that can not only communicate wirelessly but also have media playback functions have come out, for example, they can play music (such as music files in file formats such as mp3 and wma) and movies (such as files in file formats such as mp4). audio and video files) and other media files such as mobile phones, PDAs (handheld computers) and so on. In the prior art, the media files in these wireless communication handheld devices are mainly obtained through three ways: 1. By connecting with a computer, downloading the relevant files in the computer to the handheld device; Download the required files directly from the server; 3. Through wireless transmission methods such as infrared or blueto...

AI Technical Summary

Problems solved by technology

The above-mentioned first method greatly limits the portable application of handheld devices, because computers are not available anytime and anywhere; in the second method, the type and number of files stored in the server providing the service are limited, and it is difficult to meet the needs of a large number of users. Various requirements; obviously, neither of these two methods can realize file sharing between handheld devices

Although the third method can realize file sharing between handheld devices, it has great limitations, because the communication between the two wireless devices requires a consistent communication protocol, and currently each handheld device provider has its own and is not compatible with each other. protocol; and this method can only transmit in short distances
