Fig. 3 is communication method for vehicle system flow chart of the present invention.Below in conjunction with Fig. 3, communication method for vehicle system of the present invention is described.
As shown in Figure 3, this communication method for vehicle system comprises:
Step S10, sets download policy in service centre in advance, and download policy comprises the corresponding relation between download parameters and the parameter of network parameter and/or download file.
With reference to figure 3, concrete, described in advance service centre set download policy can comprise step:
First, user sends download policy by user terminal to service centre 200, and for example user terminal can be PC, mobile phone or car-mounted terminal etc., describes in the present embodiment as an example of car-mounted terminal example.User sends download policy by car-mounted terminal 100 to service centre 200, for example send user profile by car-mounted terminal 100 to service centre user, carry out after lander loading system, can input download policy configuration information by the man-machine interaction unit of onboard system 110, download policy is arranged to (download policy is sent to service centre 200).Wherein, download policy comprises the corresponding relation between download parameters and the parameter of network parameter and/or download file.Corresponding relation between size and the downloading data bag size of download file for example can be set; Corresponding relation between size and the network download frequency of download file can be set; Corresponding relation between network speed and data package size can be set; Corresponding relation between network speed and network download frequency can be set; Corresponding relation between application urgency level and the data package size of institute's download file can be set; Corresponding relation between application urgency level and the network download frequency of institute's download file etc. can be set.Preferably, the parameter of described download file comprises file size, form and/or priority.Preferably, described network parameter comprises network transfer speeds and/or bandwidth.Preferably, described download parameters comprises size and/or the download frequency of the packet of download.
In addition, setting download policy in service centre in advance can also be: the download policy that user terminal is set from service centre's selective system.The download policy (as the set meal etc. of conversing) for example in service centre with default, user can pass through the download policy that user terminal (car-mounted terminal, PC or mobile phone etc.) is set from service centre's selective system.
Then, service centre 200 receives after download policy, download policy is sent to arithmetic element 220 by communication unit 210, arithmetic element 220 is decoded, and store download policy into memory cell 230, store the corresponding relation between download policy and the car-mounted terminal 100 of transmission download policy into logic of relations unit 240.
Step S20, car-mounted terminal 100 receives the download policy corresponding with the active user of this car-mounted terminal 100 from service centre 200.
This step can be: user sends user profile by car-mounted terminal to service centre and logins; Car-mounted terminal receives the download policy corresponding with described car-mounted terminal of service centre's feedback.
For example concrete, continue with reference to figure 3, log in after service centre 200 at described car-mounted terminal 100, or after car-mounted terminal 100 starts, car-mounted terminal 100 and described service centre 200 connect, for example, connect by GPRS and/or 3G network.After connection, car-mounted terminal 100 sends download request to service centre 200, the download policy of these car-mounted terminal 100 correspondences is inquired about in the logic of relations unit 240 of service centre 200 from memory cell 230, then this download policy is sent to the car-mounted terminal 100 of request by communication unit 210.
In other embodiments, this step can also be: user sends download policy inquiry request by car-mounted terminal to service centre, and described download policy inquiry request is carried user profile or the car-mounted terminal information corresponding with user profile.Then, car-mounted terminal receives the download policy corresponding with described car-mounted terminal of service centre's feedback.
Step S30, car-mounted terminal 100 obtains parameter and the network parameter of download file.
Continue with reference to figure 3, car-mounted terminal 100 obtains the parameter of its file that will download from service centre 200, the size of for example file and form, and obtain network parameter, for example network transfer speeds and/or bandwidth, can also obtain the application urgency level of this download file.
Step S40, car-mounted terminal, according to the parameter of described download file and network parameter, obtains corresponding download parameters from download policy.
Continue with reference to figure 3, car-mounted terminal is according to the parameter of described download file, for example, according to the size of download file, and network parameter, for example network speed obtains corresponding download parameters from download policy.For example less at download file, and in the slower situation of network speed, what downloading data bag in download policy can be arranged is less, higher by Internet Transmission set of frequency in download policy.For example, for the higher download file of urgency level, what downloading data bag in download policy was arranged is larger, higher by Internet Transmission set of frequency in download policy.
Step S50, car-mounted terminal 100 sends download parameters to service centre 200, and service centre 200 sends download file according to described download parameters to car-mounted terminal 100.
Continue with reference to figure 3, car-mounted terminal 100 obtains after download parameters from download policy, this download parameters is sent to service centre 200, service centre 200 sends download file according to this download parameters, for example service centre 200 is according to size and the download frequency of the downloading data bag receiving, the file that will download is divided into several packets, sends according to described download frequency.
Communication method for vehicle system of the present invention can be set download policy in advance by user in service centre, user can be according to the needs of oneself like this, set the priority of download file, and set size and the download frequency of the packet of downloading time transmission according to the situation of network and download file, in the time downloading, car-mounted terminal has obtained from service centre size and the download frequency that download policy, just can determine according to the situation of network condition and download file the packet of downloading like this, conflict while having avoided like this file to download, and download file faster, thereby for user provides more efficient information service.
Although the present invention with preferred embodiment openly as above; but it is not for limiting the present invention; any those skilled in the art without departing from the spirit and scope of the present invention; can make possible variation and modification, therefore protection scope of the present invention should be as the criterion with the scope that the claims in the present invention were defined.
