The invention discloses an LTE (Long Term Evolution) switching method based on high-speed
train double-antenna linkage, and mainly solves the problem that in the prior art, the switching success rateis low and the network quality is influenced due to the fact that a TD-LTE
system moves too fast in a high-speed railway environment. According to the scheme, the method comprises the following steps:1, ; an LTE antenna and an
access control unit which work independently are arranged at the head and the
tail of a high-speed rail
train respectively; the vehicle head antenna is switched firstly; then, the consistency and the determinacy of the head-
tail switching environment of the
train are utilized; according to the method, the vehicle head antenna switching data is synchronized to the vehicle
tail antenna, and the related parameters are adjusted and optimized based on the
evaluation result when the vehicle tail antenna is switched according to the evaluation of the switching effect of the vehicle head antenna, i.e., the switching process and data of the vehicle tail antenna are dynamically adjusted and then the switching is carried out, so that a better switching effect is obtained.According to the invention, the switching performance of a mobile user in a high-speed motion scene is effectively improved, and the overall
network service quality of a train is optimized.
