The performed concrete operations of server side are below described:
Fact is checked, token spends and session
According to one embodiment of present invention, check for fact, need session id;
For queued session ID, the client sends following information to server:
1) mobile terminal ID: i.e. unique ID of mobile terminal;
2) session id: if the user is upgrading existing session id, original session id need to be offered server.
Server will check following content:
1) ID by mobile terminal obtains the user ID that is linked to this mobile terminal;
2) if user ID exists, check that the existence of available token in user account is to deduct;
3) if token can be used, deduct a token from this user's account, and distribute a new session id.Session id have the predetermined time limit (for example, 60 minutes are available, and 15 minutes overtime, if not relevant to any session of the system interaction content of user, the time that certainly herein sets is all adjustable).
Check request for each fact, session id need to be provided, otherwise server will not return results.
Check for fact, server side is worked as follows:
Position (longitude and latitude) from each report of all users will be converted to " piece coordinate (tile-coordinate) " (http://www.maptiler.org/google-maps-coordinates-tile-bounds-pro jection/) with predetermined level of zoom (zoom level).
Server is grouped into a plurality of independent position message on same on a vehicle.To according to the quantity of the single position message on same, calculate confidence level.
Live vehicle location shown on user terminal calculates the weighted average of time (current time deducts report time) by single position.For example, be weighted on average according to the difference of one or more described segment coordinates (tile coordinate) with respect to current time and report time.Due to travelling of vehicle, the data that different time is reported can have influence on the accuracy of calculated value, and report time and current time are more approaching, and reliability is stronger, so can be weighted on average with respect to the time according to the position of reporting.Weighted average is only a kind of account form wherein, obviously it should be appreciated by those skilled in the art that and can also adopt other account forms.
Stroke report and report session
In order to begin to report stroke, user's (mobile terminal) will ask a report session id.The report session id is used for showing whether the stroke report is qualified when whole report flow process finishes, to obtain a token.
