摘要
Abstract
The vehicle-ground wireless communication of Harbin City Rail Transit Lines 2 and 3 adopts the LTE-M scheme.The signal system builds a LTE-M based network platform to comprehensively carry signal CBTC services,wireless broadband clusters,train operation status monitoring and emergency text services.Based on the construction experience of Harbin Rail Transit Project Lines 2 and 3,this paper studies and summarizes the LTE-M network architecture,system composition,and system functions,and analyzes the LTE integrated bearer of rail transit,including bearer service solutions,frequency band allocation solutions,core network configuration solutions and wireless coverage solutions under different engineering conditions,providing certain experience for subsequent rail transit line construction and the application of LTE-M integrated bearer.关键词
