Improved Safety and Performance at Lower Cost

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However, radio driver-signaler communication often relies on outdated, analogue radio networks, supplied by multiple vendors.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 all these problems using multiple innovative, industry-standard technologies to meet the railway communications requirements of the 21st century, offering stability and reliability across various industry-specific signaling standard systems.

The Huawei Operations Communications Network for Railway helps implement a highly reliable, elastic, and evolvable end-to-end communications network. Such a network improves safety and reliability yet reduces operational costs, protecting investments made in infrastructure and rolling stock.

Indeed, Huawei’s Railway Solutions comprehensively cover the three key aspects of railway communications: mission-critical dispatch; system-wide backbone (system-wide interconnection); and broadband trackside devices. The Solutions are already being used around the world — including in Europe, Central Asia, the Middle East, and North Africa — consistently improving 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
Huawei’s Railway Operations Communication Solution supports more than six types of interface — ranging from Foreign Exchange Station (FXS) to GE. These interfaces handle access for various audio, video, and data services along railway lines, support emergency rescue, prevent and monitor disasters, audit train safety, support power system telemechanics, and monitor railway crossings.
