The road scene is an important image window of wireless network quality. Due to the fast moving speed of the terminals

the optimization of handover performance is the key of ensuring service quality and user perception. In the reality

due to the complexity of LTE network construction

there are lots of factors that cause network switching performance degradation

such as reverse handoff

cross-region coverage

redundant adjacent region

etc. To improve the LTE network switching performance

a switching chain optimization method for road scenarios is proposed

and the effectiveness of the proposed method is proved by practice.
