Embodiment 1
[0067] Please refer to Figure 1-2 , Embodiment 1 of the present invention is: a vehicle type identification method based on base station switching. This method is suitable for vehicle type identification on expressways, because the structure of the highway network is relatively simple, and the base station switching of vehicle-mounted mobile terminals basically satisfies the need for vehicles to operate. The rear base station switches to the law of the vehicle running the front base station. However, urban roads may not meet the law of switching from the base station behind the car to the base station in front due to the complex curvature of the road network and the high density of base stations.
[0068] Furthermore, on the base station with E-CID positioning function, since the base station has an array antenna, the base station can judge the direction of the source of the terminal signal while receiving the wireless signal of the mobile terminal, so as to know the directio...
Embodiment 2
[0086] This embodiment is a computer-readable storage medium corresponding to the above-mentioned embodiments, on which a computer program is stored, and when the program is executed by a processor, the following steps are implemented:
[0087] Each base station separately collects the signal direction angles of passenger cars and commercial vehicles when switching to the base station, and calculates the first direction angle characteristic interval corresponding to passenger cars and the first direction angle characteristic interval corresponding to commercial vehicles according to the signal direction angles of each base station. Two direction angle feature intervals;
[0088] When a base station detects that a mobile terminal is handed over to the base station, acquire the signal direction angle of the mobile terminal;
[0089] Comparing the signal direction angle of the mobile terminal with the first direction angle characteristic interval and the second direction angle ch...
