Success in the railway industry depends on safety, reliability, and affordability, with both operators and passengers expecting flawless service — but this requires communications networks that perform to the highest level.
However, radio driver-signaler communication often relies on outdated, analogue radio networks, supplied by multiple vendors. These are expensive to maintain and can only offer limited functionality, often resulting in uncoordinated dispatching.
Huawei addresses these problems using multiple innovative, industry-standard technologies to meet railway communications requirements of the 21st century, offering stability and reliability across various industry-specific signaling standard systems.
Huawei helps to implement a highly reliable, elastic, and evolvable end-to-end communications network, covering the three key aspects of railway communications: mission-critical dispatch; system-wide backbone (system-wide interconnection); and broadband trackside devices. Such a network improves safety and reliability yet reduces operational costs, protecting investments made in infrastructure and rolling stock.
Indeed, Huawei innovations are already in use globally — including in Europe, Central Asia, the Middle East, and North Africa — and have proven to consistently improve safety, reducing operating costs and raising overall railway performance.
GSM-R Wireless Network Ensures Reliability
Huawei’s GSM cellular technology — optimized for Global System for Mobile Communications-Railway (GSM-R) — has the most-comprehensive redundancy design in the industry for Network Entities (NEs). Introducing multiple Huawei-proprietary technologies and protection mechanisms, the GSM-R wireless network prevents single points of failure, ensures service security and reliability, and provides robust recovery capabilities in emergency situations.
Hybrid MSTP Provides Reliable Networking
Optical Transport Network (OTN) and Multi-Service Transport Platform (MSTP) standards provide the capabilities for implementing Automatically Switched Optical Networks (ASONs) at the rail network’s backbone, convergence, and access layers. ASONs are protected using a variety of measures, including Multiplex Section Protection (MSP), Subnetwork Connection Protection (SNCP), and 50-millisecond failover protection.
Broadband Transmission Supports Trackside Multi-Service Access
Supporting more than six types of interface — ranging from Foreign Exchange Station (FXS) to GE — Huawei technology handles access for various audio, video, and data services along railway lines, supports emergency rescue, prevents and monitors disasters, audits train safety, supports power system telemechanics, and monitors railway crossings.
The industry’s most-comprehensive redundancy design for NEs, ensuring 99.999% reliability.
Hybrid MSTP supports evolution to an all-IP transmission network; GSM-R can evolve to LTE-R.
Huawei meets extensive end-to-end rail communications specifications while anticipating future railway requirements.
