Description
Technical field
The present invention relates to fields of communication technology, it particularly relates to a kind of document down loading method and system.
Background technique
Internet era, mobile terminal have popularized one of the tool as people's indispensability, many times mobile terminal generation
It has replaced computer to realize that people surf the Internet demand substantially, has occupied more and more important specific gravity in people's daily life.It is mobile at present whole
End is most to rely on wireless networks, although the wireless networks such as 4G, 5G throughout the public places such as the office building in city and dining room,
It is or some regional signals and unstable or be not covered with to be arranged in some remote districts, also rely on 2G, 3G etc..Institute
It, when downloading file, can still be limited by factors such as signal strength or weakness, network bandwidths with user by wireless network, downloading speed
Degree is slow, affect experience.
It is current in the prior art, patent CN105391805A " based on multi-client cluster cooperation data downloading system
And method for down loading " in disclose it is a kind of based on multi-client cluster cooperation data downloading system and method for down loading in, in framework
Server, task the distribution server and downloading client cluster are generated including task, task generates server and distributes clothes to task
Business device provides downloading task, and task the distribution server coordinates specific downloading task and multiple downloading clients is simultaneously transferred to complete downloading,
And download that client functionality is simple, it is small only to provide basic network downloading and frequency control function, resource occupation, can abundant benefit
With existing cloud computing resources, deployment provides download service at downloading cluster by more downloading groups of clients, and can be deployed in
Different zones, different clouds, downloading client can with horizontal extension and arbitrary extension, thus reach maximum reasonable using rare
IP resource.
The method the problem is that: the cluster relates generally to the large scale equipments such as server, involved in downloading process
Task generates server, the distribution server, download server and all has a single function, i.e. generation server is only responsible for generation task,
The distribution server only undertakes the responsibility of task distribution, is a kind of waste of degree to server resource in this way；And this method pair
It does not refer to, can not be applied in the scene using mobile terminal downloading file in the scene of wireless communication.
A kind of resource-sharing is disclosed in patent CN105516324A " a kind of resource share method, system and terminal device "
Method, comprising: establish the WLAN between second terminal equipment, wherein second eventually described in first terminal collaborative share
The connection network function of first terminal equipment described in the connection network function of end equipment or the second terminal collaborative share；It is logical
It crosses the WLAN and the first shared resource information of first terminal equipment is sent to the second terminal equipment, so that
The second terminal equipment is according to the first shared resource of the first shared resource information sharing；It is connect by the WLAN
It receives the second shared resource information that the second terminal equipment is sent and stores the second shared resource information, according to
Second the second shared resource of shared resource information sharing.
The method the problem is that: first terminal equipment rely on second terminal equipment connection network function (than if you need to
Second terminal is wanted to share hot spot), it is equivalent to the network-connectivity that two terminals share a terminal, with this condition, for
The networking capability of first terminal itself is a kind of waste, and network stabilization relies on by force and second terminal.For file download,
Although second terminal can share the resource information of first terminal, file download is still completed by stand-alone terminal, and right
It is not referred in cluster high-speed downloads.
The slower problem of file detection is downloaded in a wireless communication environment for mobile terminal in the related technology, at present not yet
It puts forward effective solutions.
Summary of the invention
