Urban Rail Operational Communication Solution

Zhengzhou Metro discusses world's first LTE-enabled urban rail line

Urban rail transit is an important part of urban infrastructure and the most convenient and safe transportation mode in cities. To maximize the advantages of urban railways, more and more countries are increasing their investment in the urban rail industry and developing ICT-enabled applications to provide more convenient transport services for the public. Meanwhile, emerging economic and technical trends are bringing new challenges to ICT construction in the urban rail sector.

To help customers address these trends and challenges, Huawei Urban Rail Operational Communication Solution adopts LTE wireless technologies and all-IP carrier networks.

The new challenges to ICT construction in the urban rail sector are:

  • With higher and more diversified requirements on urban rail operational management, train-to-ground wireless communications networks need to be more reliable, secure, and have larger transmission bandwidth
  • With the development trend towards IP-based and broadband networks, plus the rapid growth of IP services such as CCTV and multimedia advertising, urban rail communications networks are experiencing an explosive increase in bandwidth-hungry services. Traditional carrier networks cannot meet the requirements of these emerging services
  • LTE technology is currently the most advanced wireless communications technology as defined by 3GPP. It is a future-oriented choice for train-to-ground wireless communications

To help customers embrace these new trends and challenges, Huawei Urban Rail Operational Communication Solution adopts LTE wireless technologies and all-IP carrier networks to allow multiple services such as train control, dispatching, PIS, and video surveillance all to be carried over one network. Allowing multiple services to be carried together improves the utilization of network resources, ensures safe urban rail operations, and generates greater revenues. Huawei Urban Rail Operational Communication Solution includes three sub-solutions:

Urban Rail LTE-M Solution

Huawei Urban Rail LTE-M Solution offers a complete set of train-to-ground wireless communications networks that meet the requirements for driving command, train control, passenger information, and onboard video surveillance services in urban rail transit scenarios. The solution features dedicated-frequency dual-network design that ensures reliable communications, long-distance coverage design that supports unified train-to-ground O&M, and multi-service unified carrier design. It addresses the problems in current urban rail train-to-ground communications networks and improves overall operational efficiency.

Urban Rail Agile IP Network Solution

To keep up with the move towards IP-based and broadband networks, Huawei Urban Rail Agile IP Network Solution provides next-generation urban rail carrier networks based on NE series routers and switches. The networks feature high security, reliability, flexibility, and unified transmission of multiple services.

Next-Generation Urban Rail DCS Solution

Based on LTE technology and NE series routers, Huawei Next-Generation Urban Rail DCS Solution provides urban rail signaling systems with optimal carrier networks that feature high-reliability design and multiple anti-interference capabilities. The flexible, reliable, and agile DCS networks turn over a new leaf in DCS systems.

Huawei Urban Rail Operational Communication Solution aims to help customers construct evolvable 4G and all-IP operational communications networks and train-to-ground wireless broadband networks based on Huawei’s 4G LTE technology. Huawei is committed to working with customers and partners to build better-connected, more efficient, secure, and convenient urban rail transit networks.
