China's Ministry of Railways (MOR) selected Global Systems for Mobile Communications-Railway (GSM-R) technology from Nortel Networks.
As a component of the European Rail Traffic Management System (ERMTS), GSM-R transports voice, data and advanced European Train Control System-2 (ETCS-2) signaling data at high speeds, said Nortel.
The wireless network is designed to provide communications capabilities between trains and ground staff along the 510 kilometer (km) passenger line between Zhengzhou and Xi'an.
Features such as group calls, connections based on the train's position, prioritization of calls during emergencies and connection to employees by function rather than name are designed to ensure the response necessary for train operation, according to Nortel.
In May 2006, Nortel signed an agreement with the MOR to deploy GSM-R to seven of MOR's 19 switching centers at Xi'an, Chengdu, Harbin, Nanchang, Lanzhou, Kunming and Urumqi.
This will enable the MOR to maximize traffic on the Zhengzhou-Xi'an line, which is a rail route that is expected to promote trade and economic exchanges between eastern and western China.
