Siemens, one of the world's largest electrical and electronic companies, covers its footprints in a full range of industries, such as energy, transportation, and security. Huawei is a leading global ICT solutions provider and is dedicated to providing better solutions and products for customers. In 2012, Huawei and Siemens CVC combined their leading products and technologies to jointly unveil the railway operation communications solution, and successfully completed the interoperability testing (IoT) between their systems. These facts ensured that their interfaces and protocols can be seamlessly compatible in the joint solution, making efficient, reliable scheduling voice bearer service a practical reality.
More and more importance is attached to sustainable development around the globe. Against this backdrop, high efficiency and security is required for the railway industry, which can be achieved by a new round of the information and communications technology (ICT)-based construction. With the widespread application of ICT technologies, railway transportation scheduling tends to be centralized, high-speed, and heavy-haul. As the transportation and service systems become more advanced, the traditional very high frequency (VHF) or ultrahigh frequency (UHF) wireless system fails to meet the increasing railway service requirements. In this situation, the railway industry demands a more advanced communications system.
To help the railway industry build a digital wireless communications network to cope with the emerging railway transportation requirements, Huawei has joined hands with Siemens CVC to provide a holistic railway operation communications solution that features high reliability, flexibility, and scalability.
The following figure shows the panorama of the railway operation communications solution.
The railway operation communications solution simplifies the system implementation and integration and improves delivery efficiency. Also, this solution provides a centralized user-friendly portal for easy operations to reduce operation and maintenance (O&M) costs.
As part of this solution, Siemens CVC provides the siriOSS system and scheduling terminals. This solution has the following features:
- Flexibly interconnects with the siriOSS system and scheduling terminals from Siemens CVC to shorten the IoT time.
- Implements end-to-end management efficiently and locates faults quickly and accurately.
- Supports user charging and registration.
- Reduces 70% troubleshooting workload for field engineers.
Huawei leverages its proprietary Global System for Mobile Communications – Railway (GSM-R), transmission, and IP products and partners with industry's leading auxiliary product suppliers such as Siemens CVC to provide the operation communications solution for the railway industry customers by deploying a highly reliable, flexible, and evolving digital wireless communication system.
By adhering to the high availability, reliability, and security design standards, the railway operation communications solution provides multiple industry-leading technologies and protection mechanisms to ensure secure and reliable scheduling communication services.
With rich experience in the communication industry and deep understanding of the railway industry, Huawei teams up with its partners to roll out the flexible operation communications system. This system brings the following benefits: high adaption to the complex railway environment, easy deployment and management, lowered site investments, and reduced operation costs.
Depending on its insight into the communication industry's development trend and full awareness of the railway industry's construction, Huawei as well as its partners such as Siemens CVC delivers the future-proof railway operation communications solution to support smooth evolution and protect the existing investment.
In the solution jointly with Siemens CVC, Huawei provides GSM-R, transmission, and enterprise network products, and Siemens CVC provides the advanced siriOSS system and scheduling terminals. Siemens CVC's scheduling terminals support the European Integrated Railway Radio Enhanced Network (EIRENE) so that central dispatchers and on-duty personnel at stations can perform scheduling more efficiently. The siriOSS system provides unified network management.
The joint solution is highlighted by the following technical features:
- Siemens CVC's siriOSS PSA system manages home location register (HLR) user data in Huawei's GSM-R system through the standard Simple Object Access Protocol (SOAP) interface and provides additional functions that are easy to use, maintain, and manage to improve the scheduling efficiency.
- Siemens CVC's siriOSS FiRe&iNMS system interworks with Huawei's network management system to locate, analyze, and rectify network faults more efficiently, improving the network management efficiency.
- Siemens CVC's dispatcher interworks with Huawei's media gateway (MGW) through the primary rate access (PRA) interface to establish a reliable and secure scheduling voice channel between central dispatchers and train drivers to ensure smooth voice communication.
On October 19, 2012, the IoT between Siemens CVC's siriOSS iNMs&FiRe system and Huawei's GSM-R network and U2000 system was successfully performed in Huawei's Xi'an Research Center.
On October 31, 2012, the IoT between Siemens CVC's IFDS GSM-R Dispatcher system and Huawei's GSM-R network was successfully performed in Huawei's Xi'an Research Center.
On January 26, 2013, the IoT between Siemens CVC's siriOSS PSA system and Huawei's GSM-R HLR system was successfully performed in Huawei's Suzhou Research Center.
