In reference to Euroradio safety protocol which is defined in ERTMS standards, CTCS-3 board-ground communication protocol is designed with domestic reality.

The CTCS-3 Simulation and Test Platform;

In accordance with the "advanced, sophisticated, economic, applicable and reliable" requirement, Our country 300km/h and above, high-speed passenger line to determine CTCS-3 Train Control System as a unified technology platform, the whole railway system, and is compatible with CTCS-2 Control System implementation CRH train running on line.

And traffic lines for passenger which from Wuhan to Guangzhou, Zhengzhou to Xian, as well as Beijing to Shanghai have decided to use CTCS-3 train control system.

That CTCS level 3 train operating control system onboard-trackside equipments communicate by using GSM-R is to fulfill the high-speed railway requirements.

In addition,all the phases in the life cycle of CTCS level 3 train control system is validly assessed in order to guarantee the high-speed control system to fulfill the requirements of high speed railway.

In order to efficiently exploit high performance network, researchers have developed many user-level protocols, which can achieve high bandwidth and low latency the bottom hardware supplies.
