Set up unit 23, receive the linking request that described loading source positioning navigation terminal sends in the Preset Time after determining in the linking request that transmitting element 22 certain frequencies send to send described linking request arbitrary time, then link successfully.
Optionally, reach preset upper limit or surpassed Preset Time if transmitting element 22 sends the linking request number of times, then set up unit 23 and abandon link.
At this moment, server can point out positioning navigation terminal and loading source positioning navigation terminal again to login, and also can select other loading source positioning navigation terminal for positioning navigation terminal and attempt link.
As shown in Figure 3, positioning navigation terminal corresponding shown in Figure 2, the embodiment of the invention provides a kind of positioning navigation terminal, as the loading source positioning navigation terminal, comprising:
Receiving element 31 is used for the link notice that reception server sends, and described link notice comprises the information of positioning navigation terminal.
Transmitting element 32 is used for sending linking request according to described link announcement period to described positioning navigation terminal.
As seen from the above technical solution provided by the invention, positioning navigation terminal is from loading source positioning navigation terminal downloading data, avoid too much positioning navigation terminal all must be huge from the load that the server downloading data causes, download untimely defective, improve the promptness that data are downloaded, improve the positioning navigation terminal user and experience.
Optionally, transmitting element 32 can send linking request with certain frequency.
Further, transmitting element 32 can also for after linking with described positioning navigation terminal foundation, send to described positioning navigation terminal with the data file information tabulation.
Thereby, the data file information tabulation that positioning navigation terminal sends according to server, check whether the data file that needs download is arranged, again be communicated with the loading source positioning navigation terminal and pass the data file information tabulation come and compare, and then select loading source and send download request, to obtain the data file that needs.
The positioning navigation terminal of the embodiment of the invention can also comprise:
Download unit is used for the download request according to described positioning navigation terminal, and the data file of asking is sent to described positioning navigation terminal.
As shown in Figure 4, a plurality of positioning navigation terminal 41 logon servers 42.As shown in Figure 5, the data download method of the embodiment of the invention comprises:
Step 51, positioning navigation terminal is logined to server, and server obtains log-on message from positioning navigation terminal.
Described log-on message can comprise: the information such as user ID, IP, port, software version or map datum version, upload and download uninterrupted, network condition.
Step 52, server be according to log-on message and the matched rule of positioning navigation terminal, for positioning navigation terminal is selected loading source from other listed positioning navigation terminals, and sends the link notice to positioning navigation terminal and selected loading source.
Here loading source can be for a plurality of, such as 10,20,50 etc., can be arranged by the user.
Matched rule can comprise: 1) positioning navigation terminal under the same local area network (LAN) is preferential; 2) positioning navigation terminal that the network bandwidth is higher is then more excellent; 3) there is nearer positioning navigation terminal of nearest time of data upload flow more excellent; 4) positioning navigation terminal that the downloading data flow is more is more excellent; Etc..Especially, when the network that detects positioning navigation terminal is the paying wireless networks such as 3G network or GPRS network, can only download desired data by server so, and not by linking download with other positioning navigation terminals, when the network that only detects positioning navigation terminal is wifi network etc. without the network of traffic fee, just can select other positioning navigation terminals as loading source for positioning navigation terminal.
After step 53, positioning navigation terminal received the link notice that server issues, positioning navigation terminal sent linking request according to the link notice to loading source.
