ei Future-Oriented LTE for Rail Solution

With the rapid development of railway transport,

simple voice and constraint data services can not

satisfy the high-speed data requirements both

from train operators and from passengers. For

train operators, a more efficient way to guarantee

train operational safety and on board security is

becoming more and more important. Services such

as on board broadband video service are beyond

the reach of GSM-R but are readily available

on Huawei’s LTE solution. For the passengers,

many people are enthusiastic about using mobile

broadband services while on the move with

laptops, mobile phones and cloud computing

devices. Many business travelers today have the

ability to connect to their work space from outside

the office. Continue working while travelling allows

travel time to be converted into productive working

hours. With the understanding of rail operational

Huawei eWBB LTE solution can support broadband service

demands as well as rail passenger communication

demands, Huawei eWBB LTE solution is designed

to providing broadband services that are far

exceeding capabilities of standard GSM-R. Video

surveillance solutions implemented on board,

along the track or on platforms help to further

improve Railway services and customer satisfaction

by allowing centralized security staff to monitor

situation on individual trains. At the same time the

system can be configured to deliver broadband

wireless connectivity to passengers allowing them

to access up to date travel information, access

internet services during the trip or watch real-time

TV. With its wide portfolio, Huawei is the right

partner for railways to pull all these technologies

together into one Smart Railway solution allowing

railways to focus on passenger needs and railway

operational demands.

Current Communication Service Requirements for Railway Industry

Huawei eWBB LTE solution permits railways to

establish high speed Broadband Data connections

on board the train. As for GSM-R, LTE based

eWBB includes specifically designed algorithms

to deliver superior Quality of Services at highest

train speeds. Huawei’s solution has been tested

at speeds of 430km/h on Shanghai’s Maglev

line. Based on LTE technology, Huawei’s solution

on maglev with FDD 20MHz, 2 × 2 MIMO

configuration, the Peak downlink rate can reach

50Mbps. With its flat network architecture eWBB

is a cost efficient solution delivering shortest bit

transfer delays. Overall reliability of the system is

rail telecommunication solution merging synergies

between GSM-R operation, non safety critical rail

operational voice and data services and passenger

communication.

CCTV cameras installed along the track provide

video feeds from trackside, platforms or specific

hot spots such as level crossings. This information

is fed into centralized control centers, stored in

Huawei’s data cloud solution, processed by our

video analysis software and transmitted via eWBB

into the train or played back for analysis. This

implementation allows ground based staff as well

as staff on board the train to have visibility well

ahead of the train. In connection with eWBB,

cameras can also be installed inside the carriage

allowing surveillance inside the coach through

centralized ground based staff or mobile security

units along the line. Huawei’s CCTV solution

allows real time video analysis and storage of video

streams in Huawei’s Data Centre solution for post

incident analysis.

Synchronization of locomotives

Our customer awarded Huawei to help them with

a solution to double their actual cargo capacity

in order to meet a targeted 350 million tons

transportation capacity per year. Our solution helps

the operator to reach their targets by providing

multi-locomotive synchronization control command

transmission, substantially enhancing the carrying

capacity of each train. In order to meet the

operational demands, both traditional data service

and broadband service were offered.

Board Level Redundancy:

One RRU can be connected with two LBBP (LTE

Baseband Processing) boards working in a local

redundancy mode. In case functions on one LBBP

board fail, services are automatically provided

through the redundant board.

Huawei’s eCNS600 main board supports 1+1

standby mode ensuring highest reliability figures.

Network Element Backup:

Huawei’s railway solutions support 1 +1 core

network redundancy through geographical

redundant nodes. For an example one eNodeB

connects to two eCNS and one eCNS connects two

PTT servers further improving the overall system

reliability.

Redundancy of the radio coverage is critically

important for railway operation. For this reason

Huawei introduced the unique concept of a Master

eNodeB and a Slave eNodeB. The eNodeB’s are

deployed along the track to provide redundant

coverage. Without manual intervention the slave

eNodeB will take over from the master eNodeB

in case of loss of function (i.e. fire, flood..) of the

master eNodeB.
