Think this with extensively getting off in current base station.Since base station range is 400m or so, bus station at a distance of 800m or so, because
There are a variety of get-off stop estimation methods for this:
Scene 1: if the route only one website in a base station, it is believed that user gets off in the website；
Scene in view of this is illustrated below in conjunction with legend:
As noted above user 1, when public transport reaches S5 website, the sequence of user 1 should have transformation to remember in the base station E
Record, but the sequence of user 1 is compared, it still rests in the D of base station, therefore, it is considered that website of the user 1 in the D of base station is got off.Then
It is obtained by data, in the D of base station, which only has S4 website, therefore can speculate that user 1 gets off in S4 website, reaches and pushes away
Survey the purpose of public transport get-off stop.
Scene 2: if there is multiple websites in the route, the characteristics of according to signaling data, when equipment is had a common boundary from multiple base stations
When place, it may occur that ping-pong, the base station by the way that ping-pong occurs can determine the position of user, if therefore when user is in
Lower car state, and ping-pong occurs, the get-off stop of user can be determined by the base station of ping-pong.
For this scene, it is illustrated below in conjunction with legend:
It is assumed that method of certain user by step 4, determines that the user gets off in the F of base station, but according to data it can be concluded that
There is S6 in F base station range, two bus stations S7 can analyze the signaling data feature of the user at this time.Due to working as user
When appearing in the covering edge of multiple base stations, it may appear that signaling data is captured by multiple base stations, but since an equipment can only be
Data are generated in one base station, therefore will appear the case where signaling data jumps in multiple base stations.If it was found that the user
In F, G, H get the signaling data in tri- base stations, then it is believed that the user gets off in S7 website；If analysis obtains the user
The signaling data is got in tri- base stations in F, E, P, then it is assumed that the user gets off in S6 website.
