Railway Operational Communications Solution

Huawei applies multiple industry-standard technologies in innovative ways to meet today’s railway communications requirements. Huawei solutions cover three comprehensive aspects of rail communications: Mission-critical dispatch, system-wide backbone and broadband trackside device.

The Huawei Railway Operations Communications Solution provides the capability to implement a highly reliable, elastic, and evolvable end-to-end communication network. This communication network improves the safety and reliability of railway operations, reduces operating costs, and protects investments in infrastructure and rolling stock.

  • GSM-R Wireless Network Ensures Reliability

    Huawei’s GSM cellular technology for Global System for Mobile Communications – Railway (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 percent. 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-millisecond 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, support emergency rescue, prevent and monitor disasters, audit train safety, support power system telemechanics, and monitor railway crossings. Advanced Passive Optical Network (PON) technologies provide reliable, high-bandwidth transmission channels for communications along railway lines.
