GSM-R is a digital wireless communication system specially developed to meet railway applications. It can provide services such as wireless transmission control, emergency communication and group call communication to meet the communication needs in railway production. Huawei not only provides a complete GSM-R solution, but also has made remarkable achievements in standards development, product development and project delivery.
GSM-R is a wireless private network communication system customized to the special business of the railway industry based on the mature GSM wireless communication technology and based on the railway communication regulations of Europe and China. The main users are railway workers, including drivers, dispatchers, flight attendants, maintenance personnel and so on.
The group call, multicast, function number call and emergency call service provided by the GSM-R system can improve the communication efficiency of the staff. The carrying capacity of train control signal by GSM-R system can meet the demand of communication in the high-speed train and improve the operation efficiency of railway. For GSM-R systems, stability and reliability are the most important performance metrics for customers. At the same time, with the overall development of communication systems, how the GSM-R system evolves into more advanced communication standards in the future is also the subject of increasing concern to railway customers.
Huawei GSM-R solution has the following features: High reliability: As a bearer of ETCS information, the railway system places extremely stringent requirements on the reliability of GSM-R. Therefore, Huawei's GSM-R solution provides three-level reliability strategy: at the board level, network element level and system level, the reliability of the entire backup network can reach 99.9999%, fully meeting the requirements of high-speed railways for communications;
Huawei's GSM-R solution is developed strictly according to the latest version of EIRENE specifications to meet all functional and business requirements and to pass third-party certification. Meanwhile, Huawei GSM-R solution passed TUV certification, meeting the latest EU regulations. In cooperation with other manufacturers supporting the comprehensive IOT test to ensure that multi-device connectivity devices;
Evolutionary: The data service carrying capacity of GSM-R is increasingly insufficient and can not meet the demand of broadband services for future railway communications, such as video transmission. UIC has basically confirmed the evolution of LTE as the next generation railway wireless communications system. How to evolve from GSM-R to LTE for Rail and fully protect customer investment is a common concern of railway customers and equipment suppliers.
Huawei's GSM-R solution can support this evolution. The single-cell single-chassis core network eCNS300 adopts the ATCA platform that is consistent with that of the LTE system, and has the characteristics of high integration and high performance. The dual-mode base station BTS3900 can support the GSM and LTE modes and support the future evolution from GSM-R to LTE. Large protection of the user investment.
