The Shuohuang railway(the heavy-haul technologies) Wireless Broadband Communication System (LTE-R) is a new application of 4G network standard TD-LTE technology in the field of railways. It is also the first time in the world that the heavy haul railway is implemented. LTE-R provides more broadband, more information, safer management, more convenient service and more rapid information management for the transportation and work service of each department of Shuohuang railway. However, the coverage of the LTE-R network in a pipe section of the Shuohuang railway is complicated and the operation and maintenance of the wireless network are difficult. How to ensure the coverage of LTE-R system network security, to the professional maintenance personnel put forward higher requirements, to achieve this goal, we must continue to optimize the network, this paper proposes the use of a dynamic function to solve the problem of network coverage of ping-pang switching, by introducing a dynamic elliptic function to optimize LTE-R system network coverage handover problem. The simulation results show that the improved algorithm can effectively guarantee the success rate of handover compared with the current handover algorithm. Which is of great significance to improve the security of the network. The content of this research has considerable theoretical and practical guiding value in the application of network coverage switching in the complex terrain of heavy-haul railway.
