Huawei’s Progress in GSM-R Sochi Line — Preparing for the 2014 Winter Games in Russia

The Sochi high-speed railway is a modern transport infrastructure

being prepared for the XXII Olympic Games and XI Paralympic

Winter Games to be held in Sochi, Russia, in 2014. It is Russia’s first

high-speed railway to be put into operation in the alpine region

where outside temperatures can drop to - 40 °C and lower. Sochi’s

high-speed link is designed for speeds of up to 400 km/h operating

under an ETCS L2 train signaling system. Its total length is 157 km.

At the end of 2011, Huawei was awarded the contract to build

Sochi’s GSM-R network, including the access and core networks.

To guarantee highest reliability for the Sochi railway, Huawei is

supplying a hot-standby core network. Dual-homing Mobile Switch Center (MSC), duo-location BSC and redundant

TRX guarantee superior end-to-end redundancy for the entire network. Along the railway line, there are 12 tunnels

at a total length of 30 km. As in other projects, Huawei is installing DBS3900 distributed base stations to meet the

customer’s requirements for this complex rail environment.

Opening of the Sochi railway is considered a significant milestone to meet the passenger transport demands for

the Sochi Winter Olympics. After the Olympics, Huawei’s GSM-R solution will continue delivering services for an

improved rail transport system to the entire Sochi region and will play a significant role in tourism and the economy.



EKB Line —ERTMS L2 Multi-vendor System for Turkey

Measuring 466 km in length and designed for speeds of up to 250

km/h, the Eskisehir, Kutahya and Balıkesir (EKB) line is an integral

part of the "Nine-Year Plan for High-Speed Railway" launched

by the Turkish State Railways (TCDD). The EKB Line will greatly

enhance interconnectivity between Eskisehir, Kutahya, and other

major Turkish cities, promoting economic development in the local

communities.

Huawei was awarded the contract in 2012 to provide wireless

access equipment for the EKB project. The EKB line winds through

42 tunnels and requires high-quality GSM-R service. The rugged

terrain poses significant challenges to construction, including site selection for base stations, comprehensive signal

coverage requirements, and smooth communication throughout each tunnel. Leveraging its latest innovations in

GSM-R, Huawei offers TCDD a unique distributed base station technology. The new technology features the RRU

multi-site co-cell, which provides improved quality of service under complex situations and maximum deployment

flexibility, as well as enhanced tunnel coverage along the line.

The GSM-R communication system of the EKB Line marks the first ETCS L2 train signaling system in Turkey. The

Turkish GSM-R system represents a typical multivendor network. For this line, Huawei’s GSM-R was fully integrated

with core networks from a Finland-based GSM-R vendor.

Metropolitan Line, Australia

designed in a way to enable the customer to easily upgrade to ETCS

L2 and operate at frequencies up to 1,800 MHz.



Cape Town-Durban-Gauteng Line — Sub-Saharan Africa’s First GSM-R Railway

The Cape Town-Durban-Gauteng Railway line is in the first phase of

a countrywide GSM-R project in South Africa. This first section will

have a total length of 1,200 km and a designed speed of 120 km/

h. The Passenger Rail Agency of South Africa (PRASA) is replacing

its traditional MTP1327 analog system deployed 15 years ago.

The analog system’s purpose was to provide ground-to-train voice

services. The GSM-R digital signaling radio system will significantly

improve passenger rail transport for large portions of South Africa’s

population.

Huawei was awarded the GSM-R contract for access and core

network architectures in 2012. Huawei’s latest evolution of wireless

After completion of the first project, UAE railway passenger and

cargo capacity will be greatly improved and play a leading role in

determining planning for subsequent second and third stages.



North-South and East-West Lines —Turkmenistan Telecommunication Upgrade Project

Turkmenistan is an important transport hub for the whole

Eurasia region. The national railway system in Turkmenistan

extends over 3,600 km of rail corridors facing east-west and

north-south.

The north-south line and the 590 km-long east-west line

are the first and third phases in a total of seven phases of

Turkmenistan Rail’s communications upgrade plan. Huawei

was awarded this GSM-R contract in 2012 to implement

an end-to-end solution including wireless access, core

network and terminals. The core network is considered as

the industries most integrated GSM-R core with superior

compact, single cabinet.

Guangzhou-Shenzhen-Hong Kong Express

In December 2007, Huawei Technologies was selected to design and build a GSM-R voice and data

communication system for the high-speed line between the cities of Shenzhen and Guangzhou. The

Guangzhou-Shenzhen-Hong Kong line, using a CTCS-3 train signaling system (coherent to ETCS L2), was

China’s first operational GSM-R line with a speed designed to reach 350 km/h.

About one-third of the high-speed line runs through hilly terrain that required extensive construction of

bridges, cuttings and tunnels. The 10.8 km-long Shiziyang tunnel, being the longest, is an underwater dual-

cave shield tunnel that reflects the shape of the shuttle and leaves very little room for RF equipment.

Huawei’s BSS solution for this challenging environment consists of a combination of conventional BTS and

repeater equipment, as well as distributed base stations. Huawei GSM-R is compatible with the two signaling

systems of the mainland and Hong Kong and interworks with NSS equipment provided by other vendors. This

project speeds rail access from Hong Kong to 16 mainland cities.



Hada Line — High-speed Railway at 350 km/h

The Hada Railway project is a major high speed rail construction

project connecting the cities of Harbin in Heilongjiang Province

with Dalian in Liaoning province. The total length is 895 km of

GSM-R track. The system is designed for train speed of 350 km/h.

To ensure safe operation of this network, the line is controlled by

the Chinese Train Control System-3 (CTCS-3), which is coherent to

the European Train Control System Level 2 (ETCS L2).

Huawei was awarded the contract in July 2010 to design and

supply a GSM-R access and core network solution as part of the

National Eleventh Five-Year Plan. Huawei designed the network to

be fully compliant with the stringent requirements of the CTCS-

3 signaling system. Components include Huawei’s Softswitch

core network with MSC dual-homing and distributed base station

system.

Chengguan Railway — First GSM-R Softswitch in Rail Operation

Huawei Technologies was awarded to design and supply a GSM-R

access and core network solution for the Chengguan Railway

project. The project runs between the cities of Chengdu and

Dujiangyan in Sichuan Province. It is a railway line designed for

train speeds of up to 250 km/h.

Huawei’s R4 Softswitch core network was successfully installed

on this line, proving its market-leading network reliability. The

Chengguan project was the very first GSM-R project in China

equipped with R4 Softswitch technology, underlining Huawei’s

lead in transportation technology. Huawei not only designed, built,

and put this network into operation, but also interconnected and

integrated the Chengguan GSM-R system with other vendors’

GSM-R core networks located in Beijing and Wuhan.



Daqin Line — First Commercial GSM-R Application over GPRS to be Upgraded to IP-core

The Daqin Railway connects the city of Datong with the city of Qinhuangdao and, in 2005, became China’s first railway

line to be equipped with Huawei’s GSM-R technology.

The Daqin line is mainly used for coal transportation, and is recognized as one of the most important heavy-haul railways

in China. Trains reaching a total length of 2,700-meter-long system with up to 214 coaches operate on multiple engines

that are distributed between the individual coaches. These traction units are operated and synchronized from a single

driver using Huawei’s General Packet Radio Service (GPRS) data solution. Again, the Daqin line was the first to use this

GPRS based solution. Since the commercial launch of the line, its freight throughput has increased by 400 percent and

annual capacity has reached 400 million tons.

In order to further improve operational reliability of the end to end system the Daqin railway line was successfully

migrated from its R99 platform to a modern R4 Softswitch platform in January 2011. Huawei designed and carried out

the upgrade of the GSM-R core network without disrupting the rail operations of the Daqin line. The successful migration

of the Daqin 3GPP GSM-R network represents an important milestone for GSM-R network operators all around the world,

since many GSM-R networks today would greatly benefit from the additional features offered by an R4 platform. This

project demonstrates that high-reliability GSM-R networks can be migrated while full rail operation is maintained.

Due to the large number of tunnels, long slopes, and other complex terrain making up the

Daqin railway, traditional repeaters were installed in the initial phase of the project to meet the requirements of wireless

coverage. As cargo throughput increased, demands on wireless reliability also increased. In May 2013, the railway’s

original mobile repeater solution was replaced by Huawei’s distributed BTS DBS3900. It was the first time anywhere that

any railroad has replaced repeaters with Huawei GSM-R DBS3900.

Huawei installed 70 sets of DBS3900 distributed base stations over more than 20 long slopes, tunnels and in regions

with complex RF situations. The replacement of mobile repeaters by DBS3900 stations has greatly enhanced network

performance, improving efficiency and safety on the heavy-load Daqin Railway.
