Railway Operational Communication Solution

GSM-R Solution for High-Speed Railway

Attempts to implement centralized dispatch, improve management of both high-speed and heavy-haul trains, and diversify railway business involves a number of challenges:

  • Highly reliable connectivity is imperative between dispatch centers and trains, stations, and trackside devices
  • Providing wireless coverage for moving trains is challenging for rail lines spanning mountains, tunnels, and bridges
  • Traditional trackside communication infrastructure cannot meet the need for multi-service access and broadband transmission

Huawei meets these challenges with a series of GSM-R, Hybrid Multi-Service Transport Platform (MSTP), multi-service broadband access solutions.

Meeting railway requirements

Huawei applies multiple industry-standard technologies in innovative ways to meet today’s railway communication requirements. Huawei solutions cover three broad aspects of rail communications:

  • Mission-critical dispatch
  • System-wide backbone
  • Broadband trackside device

GSM-R wireless network ensures reliability

Huawei’s GSM cellular technology for Rail (GSM-R) has the most comprehensive redundancy design in the industry for Network Entities (NEs). Implemented with 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 the event of a disaster.

Huawei’s GSM-R solution offers unique distributed base stations. These distributed stations use a patented Automatic Frequency Control (AFC) algorithm to improve the quality of radio coverage in complex environments such as mountainous areas, tunnels, railway hub stations, and classification yards.

Huawei also uses a multi-RRU co-cell technique in which six remote radio units are configured into the same cell to reduce the handover rate by 83%. Fewer handovers mean fewer chances for communication interruptions that could cause issues with train dispatching, downgrading of signaling devices, or train stoppages.

Hybrid MSTP provides reliable networking

The Optical Transport Network (OTN) and Multi-Service Transport Platform (MSTP) standards provide the ideal capabilities for implementing Automatically Switched Optical Networks (ASONs) at the rail network’s backbone, convergence, and access layers. These ASONs are protected using a variety of measures, including Multiplex Section Protection (MSP), Subnetwork Connection Protection (SNCP), and 50-ms failover protection. Offering comprehensive safeguards at the equipment, network, and service levels, the Hybrid MSTP transmission network has the ability to prevent single-point failures caused by natural disaster or human error.

Broadband transmission supports trackside multi-service access. Huawei’s Railway Operations Communication Solution supports more than six types of interfaces ranging from Foreign Exchange Station (FXS) to GE. These interfaces handle access for various audio, video, and data services along railway lines, supporting emergency rescue, disaster prevention and monitoring, train safety monitoring, power system telemechanics, and railway crossing monitoring. Advanced Passive Optical Network (PON) technologies provide reliable, high-bandwidth transmission channels for communications along railway lines.

Versatile communications meet all rail requirements

The Huawei Railway Operations Communication Solution offers the capabilities you need to implement a highly reliable, elastic, and evolvable end-to-end communication network. This communication network helps improve the safety and reliability of railway operations, reduce operating costs, and protect investments in infrastructure and rolling stock.
