Huawei demonstrates latest GSM-R solutions at UIC HIGHSPEED 2008


Huawei Technologies Co., Ltd. (“Huawei”), a leader in providing next generation telecommunications network solutions for operators around the world, today announced that it will showcase its latest GSM-R solutions at the 6th World Congress & Trade Exhibition on High Speed Rail, organized by the UIC(International Union of Railways) in Amsterdam.

A number of Huawei’s innovative GSM-R solutions will be on show at the event including the only end-to-end solution in the world that is verified to support high-speeds of 430km/h, as well as the industry’s first distributed base station solution for GSM-R systems.

High-speed rail transportation requires a communications system with a high-level of safety and stability. From the core network to the access network, Huawei provides three designs which safeguard the reliability of GSM-R systems under high-speed. Firstly, Huawei’s GSM-R system uses dual-plane, resource pool and N+1 backup. Secondly, Huawei adopts network-level mechanisms such as MSC dual-homing, double coverage, TRX redundancy and enhanced ring networking to ensure the reliability of core networks and to realize double-coverage of access networks. Thirdly, Huawei provides unique advanced access restriction technologies including multi-level traffic control and automatic alarm systems to enhance the security of GSM-R networks.

Huawei’s GSM-R solution also uses AFC (Automatic Frequency Correction) technology to detect and offset Doppler frequency with fast handover algorithms and is fully compliant with EIRENE specifications which provide the ability to interconnect signaling systems.

Huawei completed world’s first GSM-R tests at high-speeds of 430 km/h on the Shanghai Maglev Railway in 2006. At the beginning of 2008, Huawei was selected to construct the communication system for the high-speed Guangdong-Shenzhen-Hong Kong passenger transport railway. With a top speed of 350 km/h, the Guangdong-Shenzhen-Hong Kong transport railway is one of the fastest passenger transport railway lines in the world.
