Abstract
The invention discloses a kind of big compressing file method for down loading of car networking cloud, comprise the following steps：S1:Marked vehicle enters in the coverage of a certain RSU, and cloud acts on behalf of the download request for sending specific file to vehicle according to the drive routine route and interest preference of marked vehicle；S2:Using car networking cloud, the prediction and compression of duration are downloaded to the specific file of required download；S3:Vehicle downloads compressed file from roadside unit RSU.The present invention compensate for big file download time length in car networking, be difficult to ensure that the problem of data integrity, by the way that car networking is combined with cloud computing, the compression that big file is carried out using car networking cloud is downloaded, so as to slow down resource occupation problem in communication process, and reduces period of reservation of number；The present invention can be realized under conditions of ensureing the integrality of download content and meeting time restriction, improve the utilization rate and user satisfaction of Internet resources.
Description
Technical field
The present invention relates to car networking field of communication technology, is applicable in vehicle under high velocity environment and is accessed by roadside device under network
A kind of method of data is carried, is specially a kind of big compressing file method for down loading of car networking cloud.
Background technology
As China is in the continuous propulsion of each field overall sustainable development process such as economy, science and technology, vehicle guaranteeding organic quantity
Increase sharply.While automobile quantity rapid growth, the trip requirements of people show high request, the situation of polymorphic type.People
Trip focus from initial security and efficiency, gradually extend to comfort and recreational, go out so as to pursue word
Capable maximal efficiency.Such as from the home to a traffic trip between unit, while safe and convenient is ensured, user
Wish the Business Information near acquisition approach, including business surpasses, the business hours of cinema and gas station etc., recent preferential activity
Deng；In-car non-driver downloads it may be desirable that obtaining online amusement, information service, including video, online browse net
Page etc..In order to realize above-mentioned function, the important component that car networking develops as intelligent transportation system, can effectively realize
The distribution that high-speed mobile environment Xia Cong roads are set to the big file content of audio and video class of target vehicle is downloaded.
It is existing many to improve data distribution efficiency although the distribution at present on being carried out big file using car networking is downloaded
Achievement, but the big file content for tackling user to a certain extent downloads demand, still has much room for improvement, vehicle is in single trackside list
How to ensure that the integrality of file download still needs to new solution in the coverage of first RSU.
Under car networking environment, since the behavior of vehicle, interest and hobby etc. are different, for different resource in car networking
Demand is also different, and user is also continuously increased the requirement for downloading the time and quality of big file.In order to ensure file content
Integrality and user's patient time limitation, while in view of cloud agency there is powerful calculating and compressed capability, pass through
Car networking is combined with cloud computing, in a manner of " car networking cloud ", big file is compressed and downloaded.
The content of the invention
It is an object of the invention to provide a kind of big compressing file method for down loading of car networking cloud, and content is being downloaded to realize
Integrality, reduces resource occupying, improves user experience and satisfaction.
The present invention uses following technical scheme to achieve the above object：A kind of big compressing file method for down loading of car networking cloud,
Include the following steps：
S1:Marked vehicle into a certain RSU coverage in, cloud agency according to the drive routine route of marked vehicle with
And preference sends the download request of relevant matches file to vehicle；
S2:Using car networking cloud, the specific file of required download is compressed so that meeting that download time requires；
S3:Vehicle downloads compressed specific file from high in the clouds through roadside unit RSU.
As the further scheme of the present invention, the step S1 medium clouds agency according to the drive routine route of marked vehicle with
And the process of preference to the download request of vehicle transmission specific file is as follows：
S21：When marked vehicle is into the coverage of roadside unit RSU, roadside unit RSU is by the phase of marked vehicle
Pass information is reported to be acted on behalf of to cloud；
S22：Cloud is acted on behalf of according to marked vehicle historical data, including drive routine route and preference, selectively to road
Vehicle push associated resource information in side unit RSU coverages, and establish the Resources list and be stored in RSU locals；
S23：User requires selection to download specific file according to individual.
As the further scheme of the present invention, car networking cloud is utilized in the step S2, to the specific file of required download
The process being compressed is as follows：
S31：After roadside unit RSU receives the confirmation download information of vehicle, report and acted on behalf of to cloud；
S32：Cloud agency calculates according to the type for downloading file and selects suitable compression ratio that file is met completely
Redundancy is minimum on the premise of property, availability, and carries out compressing file, ensures in user's patient time and sails out of the roadside unit
Downloading task is completed before RSU.
As the further scheme of the present invention, vehicle is downloaded compressed specific from roadside unit RSU in the step S3
The process of file is as follows：
S41：Compressed specific file is sent to roadside unit RSU by cloud agency, and roadside unit RSU receives this document simultaneously
Preserve；
S42：Roadside unit RSU confirms download information according to the vehicle received, sends the file to specific.
The beneficial effects of the invention are as follows：The present invention is different from traditional big document down loading method of car networking, it make use of cloud
The features such as computing capability is strong, processing speed is fast is acted on behalf of, by roadside unit RSU, the compression for carrying out big file is downloaded, and ensure that text
The integrality that part is downloaded, improves the performance of system；The present invention compensate for big file download time length in car networking, be difficult to ensure that
The problem of data integrity, by the way that car networking is combined with cloud computing, the compression that big file is carried out using car networking cloud is downloaded,
So as to slow down resource occupation problem in communication process, and period of reservation of number is reduced, improve the utilization rate and use of Internet resources
Family satisfaction.
Brief description of the drawings
Fig. 1 is to carry out big file download schematic diagram using car networking cloud in the embodiment of the present invention；
Fig. 2 is that flow chart is realized in the embodiment of the present invention.
Embodiment
