城市轨道交通跨线运营集群调度系统互通方案

The Interworking Scheme of Urban Rail Transit Carrying the Trunked Dispatching Service Under the Cross-Line Operation Scenario

描述了在城市轨道交通跨线运营场景下,车地无线LTE-M系统在承载集群调度业务时,和同制式的LTE-M集群系统之间以及在承载相关业务的异制式TETRA系统之间的跨线互通解决方案。从技术可行性、工程可实施性和适用场景等角度研究和阐述了相关方案,并对同场景下不同解决方案并进行了比较分析。

This paper describes the cross-line interworking solution between the train-ground wireless LTE-M system and the LTE-M system of the same system as well as between the different TETRA systems that carry the relevant services when carrying the trunked dispatching service under the cross-line operation scenario of urban rail transit.The relevant solutions are studied and elaborated from the perspective of technical feasibility,project feasibility,and applicable scenarios,and different solutions under the same scenario are compared and analyzed.
