3. Coverage scene complexity.

In the underground, wireless coverage complicated than the ground has to designed to cover

central substation of seam, central pump room, substation mining area, the main incline shaft,

auxiliary incline shaft, the main haulage roadway, auxiliary haulage roadway, mechanized

mining face, workface auxiliary transport trough.

4. Lack of One wireless network to cover dispatch building, administration building, coal

washing plant, staff quarters etc.

2.2.2 Available Wireless Frequency

This section describes the radio frequencies and bandwidth resources to be used for building

a network for XXX coalmine.

2.2.3 Coverage Area

Briefly describe the expected coverage areas, terrains in the coverage area, major mining

facilities, and geographical information that may affect the network buildup.

The following description gives an example of how to describe a requirement analysis. Change the description according to an actual project.

This coalmine has XXX slopes, XXX transportation roadways, XXX full-mechanized mining

faces, XXX master dispatching centers, XXX branch dispatching centers, ground areas of

XXX, and underground areas of XXX.

2.2.4 Business Service Requirements

This section provides major service components for the XXX coalmine network buildup according to the bidding document. You are advised to describe all the service components

separately in different sections, if needed. If a service component is included in the eLTE wireless broadband trunking network solution, such as the bearer network, trunking system, backhaul system, video monitoring system, and mobile office system, you are advised to

describe this service component in a separate section. If a service component is related to another, you are advised to describe them together in a single section. In addition, you are advised to describe these service components by referring to the bidding document. The

following description gives an example of how to describe a requirement analysis. Change the description according to an actual project.

Huge gaps remain in the field of mining safety assurance between China and developed

countries. For example, the death rate per million tons is steady below 0.74% in the United

States. Therefore, an increasing demand for a highly reliable and efficient coalmine

communication system that can promptly notify working personnel of emergency evacuation

and maintain smooth and reliable communication with the working personnel in case of a

mining emergency is placed upon mining enterprises.

To provide sound mining safety assurance, the following six underground coalmine systems

are essential, which include the monitoring and control system, personnel and vehicle positioning system, emergency system, atmospheric pressure self-help system, water supply

and rescue system, and communication system. Among these systems, the monitoring and

control system, personnel positioning system, and the communication system can be

implemented using the Huawei eLTE wireless broadband trunking network system.

To provide reliable mining safety solution, some equipment manufacturers first attempted to

use Wi-Fi solutions and SIP terminals to deliver the requirements of wireless communication

and data access services for mining sites. The Wi-Fi technology, which is based on IEEE

802.11 proposed by the International Telecommunication Union (ITU) for implementing

short-distance wireless broadband communication, features bad support of mobility and

therefore is mainly used for wireless local area networks (WLAN).

From the outset of applications of Wi-Fi solutions in mining sites, problems have been found

on many occasions. For example, users can only have communication services provided by

the access point (AP) that cover the area where the user is working, and call drops are

frequently experienced when users are moving from one cell to another. Wi-Fi services are

even found hardly available on low-speed trains or mining explosive trucks.

In addition, the APs work at the unlicensed 2.4 GHz frequency bands and provide low

transmit power, yet have to deal with high transmit frequency. As a result, the APs have

relatively small coverage areas and require dense deployment (with an interval of about 200

meters), which demands high costs for network construction. In other words, Wi-Fi solutions

can hardly meet the demands of wireless broadband communication for mining sites, even for

underground broadband access and Ethernet transmission functions.

As efforts to pursuit wireless communication solutions that can better meet the

communication requirements for coalmines, the TD-SCDMA equipment providers have

already brought into the use of explosion-proof TD-SCDMA devices in some coalmines.

These tentative applications have demonstrated satisfactory performance. However, the

TD-SCDMA solutions have their own defects in term of data bandwidth. A single

TD-SCDMA carrier can only provide a maximum rate of 384 kbit/s in the uplink and 2.8

Mbit/s in the downlink. Therefore, they are still stretched to take over the existing wired

industrial television systems and Ethernet environment monitoring systems.

As mining automation advances and dependence of information technologies deepens,

traditional wireless communication solutions can no longer meet the demands for mining

safety and wireless video multimedia services. Therefore, the mining enterprises are

increasingly demanding a broadband multimedia communication network that can help them

achieve the goal of monitoring and control, wireless positioning, and voice trunking communication in guaranteeing mining safety. (You are advised to change the functions according the customer requirements.)

The XXX customer has been attaching great importance to mining safety. At present, the

communication system in service for the XXX coalmine includes a Wi-Fi communication

system, and a TD-SCDMA communication system. (Change the communication system list according to the available communication systems of the customer. For example, if a WiFi communication system is not used, delete it from the communication system list.)

To meet the challenge, Huawei provides the eLTE wireless broadband trunking network

solution that supports a variety of demands on the mobile communication for the mining

sector.

The following summarizes the service demands for the XXX customer based on the preceding

analysis:

Communication services

Monitoring and control

Personnel positioning

…

(You are advised to list the service demands according to the customer requirements.)

the talk key to start a video call. The client of the video called party rings as a

notification of the video call. The video calling terminals need to support 720P and 1080P picturing and the video format of CIF, 2CIF, and QCIF.

Equipment operating status monitoring

Operating status monitoring of key equipment needs to be performed, such as water

pump controllers and belt PLC controllers. The monitored operating information needs to be transmitted back to the monitoring and control center in a real-time fashion.

Explosion-proof requirements

Monitoring cameras for underground uses also need to be complied with the customer's explosion proof requirements, in addition to the terminals and RRUs as described above.

Personnel and Vehicle Positioning

The XXX coalmine needs personnel and vehicle positioning services to position personnel and

vehicles for mining production and implement working personnel positioning in case of an emergency.

Terminal positioning functions

Handsets and vehicle-mounted stations can be positioned by using GPS functions. Besides, they also report their positions to the GPS servers on a regular basis.

The GPS servers can also use an electronic map to position the handsets and display the

status, locations, and directions of the handsets. At the same time, the engineer can also

choose a handset on the electronic map and make it to upload monitoring videos to the

dispatching center and distribute these monitoring videos. In addition, the locations of

fixed monitoring cameras can also be marked on the electronic map. Users can search a

monitoring camera through the electronic map and view the monitoring pictures of the camera.

Geographic information system (GIS) functions

The GIS system needs to provide common functions of a GIS system and can be

integrated with the video dispatching system so that users can choose a handset through

the electronic map to make it to start a video monitoring and upload monitoring videos to

the dispatching center and distribute monitoring videos. Users can also start an individual call with the chosen terminal.

3.2.2 Trunking Communication System

Overview

A trunking communication system allows mobile communication over one radio channel

among multiple users of different departments or user groups. Compared with a cellular

mobile network, a trunking communication system features fast call access, forward channel

sharing among intra-group users, half-duplex communication, push-to-talk (PTT) capability,

and support of private and group calls. With a trunking communication system, users can

initiate a call without dialing a number and talk to a called party simply by pressing the PTT

key. Correspondingly, the called party can answer the call without a pick-up operation. With

peculiar dispatching functions, group call performance, and fast call support, trunking

communication systems enjoy wide popularity in the dedicated communication field.

A common trunking communication example is the wired telephone dispatching system for

coalmines, which gives great convenience to coalminers' daily lives and work. However, this

system cannot meet the demands of mobile calling services for underground coalminers.

the requirements.

− A mobile terminal user, in the need of reporting something to its group members,

presses the PTT key to become a group speaker and start a one-to-all PTT talk.

− The group members receive the reporting of the mobile terminal user.

− A mobile terminal user with a floor priority higher than that of the current speaker

presses the PTT key to start a floor preemption to take over the current speaker and

become a new speaker, if he/she wants to know more details or give some

instructions.

− The speaker releases the PTT key and then the PTT talk ends. Other group members can press the PTT key to continue to request a floor and start another PTT talk.

Procedure for emergency calls

− A mobile terminal user presses the Emergency Call key to start an emergency call.

− If the system is busy, the system immediately stops a call of the lowest priority and

assigns the radio resources to the mobile terminal user for setting up an emergency call with the highest priority for this user.

Designs of SMS and MMS and Data Services SMS and MMS messages

The eLTE wireless broadband trunking system supports point-to-point,

point-to-multipoint, and point-to-group short message services (SMS) and multimedia

message services (MMS). Users can edit and send an SMS or MMS message on both

mobile terminals (handset and vehicle-mounted station included) and dispatchers.

A multimedia message contains video and audio files as attachments. Upon receiving a

short or multimedia message, a terminal prompts the user to view the received message.

If a target terminal is out of services or is powered off, the system saves the message and

resends it to the terminal when it is within the service area or is powered on.

Procedure for SMS and MMS services

− A coalmine maintenance person takes a photo of an abnormal condition and uploads the photo to the dispatching center or the specific person.

− The dispatching center sends a multimedia message with illustrative words to the engineers and other relevant personnel.

− The engineers analyze the abnormal condition through the received multimedia

message to come up with the maintenance measures and notify these measures to the

maintenance person.

Application scenarios:

Data services

The eLTE wireless broadband trunking system provides functions of

ground/underground mobile offices, which helps improve working efficiency. For

example, this system supports user-defined electronic sheets, document

sending/reception, and document examination and approval, which contributes an

effective solution to frequent changes in mining business. This system also supports the

push mail function that gives management personnel automatic notification of a new task

or new mail immediately it is received. With the help of this system, data exchange with

the coalmine automation system can be implemented, ensuring that management

personnel can have a real-time and accurate understanding of the coalmine safety conditions.

The eLTE wireless broadband trunking system allows various terminal access modes.

Users can access the eLTE wireless broadband trunking network through handsets or

through the eLTE wireless access equipment, such as a USB dongle and a CPE wireless

router. In addition, the eLTE handset can function as a Wi-Fi hotspot and mobile office equipment to provide accesses for other terminals.

The mobile office services for coalmines include:

− Remotely querying key information, such as production and dispatching information

and daily safety sheets.

− Monitoring environment data, such as coalmine gas, temperature, and humidity

− Monitoring the operating status of major equipment, such as main shafts, water pumps, coal cutters, and excavators

− Querying all alarm information of underground coalmines.

− Managing company information, such as newsletters, bulletin boards, common

services, contact directory, train schedules, flight schedules, zip codes, recommended websites, forums, visitor records, and outbound personnel records.

− Conducting meeting management, arrangement, notification, and query.

Designs of Intercommunication with PSTN and PLMN

The eLTE wireless broadband trunking system adopts a distributed architecture, and only

eRRUs are mounted in underground areas. If a power cutoff is experienced due to coalmine

gas excess or power failures for a period that runs out of the power of the eRRU batteries, the

underground eRRUs will stop working. On the other hand, the coalmine wired dispatching

and communication system can still work even in case of an underground power cutoff and

therefore is more resistant to power cutoffs. Therefore, the eLTE wireless broadband trunking

system needs to be deployed together with the coalmine wired dispatching and

communication system.

The eLTE wireless broadband trunking solution allows intercommunication with the coalmine

PSTNs and PLMNs through the gateway and therefore can solve the intercommunication

issues of mining sectors. The dispatching console can be performed by using the same

platform, which facilitates daily operations and maintenance.

(Change the description of intercommunication designs according to the specific projects.)

Explosion-proof Designs

The explosion-proof designs apply mainly to eRRUs and terminals.

The equipment in use for underground coalmines must comply with the following standards:

GB 3836 Electrical apparatus for explosive gas atmospheres

GB/T 9969 General principles for preparation of instructions for use of industrial products

GB 4208 Degrees of protection provided by enclosure (IP code)

MT 209 General Technical Requirements of Electric and Electronic Products for Communication, Inspection, and Control in Coalmine

MT 210 Basic Test Methods of Electric and Electronic Products for Communication, Inspection and Control in Coalmine

MT 211 Quality Inspection Rules for Electric and Electronic Products for Communication, Detection and Control in Coalmine

AQ 1043-2007 Mining Products Safety Label

(Change the standards of equipment in use for underground coalmines according to the

specific projects.)

3.2.3 Monitoring and Control System

Video Services

The coalmine industry television system is essential to building digital coalmines and

comprehensive automation systems and poses strong guarantees to automatic and unmanned

mining activities. This system also provides intuitive and reliable tool and reference for

mining safety, control and dispatching, and scientific decision making. The coalmine industry

television system has already been put into use in coalmines for monitoring purposes.

Coalmine environment is complex, which makes cable routing in coalmines a difficult task

and leaves many monitoring holes in the monitoring area.

The eLTE wireless broadband trunking solution allows one cell to send multi-channel

concurrent high-definition videos to the dispatching center in a real-time fashion on a network

with a bandwidth of 20 MHz. This helps meet the demands of uploading videos to the

dispatching center from multiple monitoring points. (Change the bandwidth according to an

actual project.)

Figure 3-3 shows a video monitoring network for the XXX coalmine. (It is recommended that

the frontline personnel change the networking diagram according to an actual project.)

Figure 3-3 Video monitoring network for the XXX coalmine

The following details video service procedures by using the full-mechanized mining face as

an example.

For a full-mechanized mining face, cameras are installed usually at a spacing of six to nine

meters, and it is good practice to allocate a CPE for two cameras. The video is uploaded to the

dispatching center through the CPE.

The application server of the dispatching center chooses the four cameras nearby the coal

cutter as it moves, or the dispatching center randomly chooses cameras on the

full-mechanized mining surface. Then, the monitoring pictures of the chosen cameras are

uploaded to the dispatching center and displayed on the big screen.

The monitoring center of the full-mechanized mining surface in the transportation roadway

connects to the eLTE networks through the CPEs. In this way, these pictures displayed on the

screen in the dispatching center or the pictures of other cameras on the full-mechanized

mining surface can be displayed in the monitoring center.

In this solution, the interfaces of the core network use all-IP architecture. This helps integrate

this system with existing application systems in the coalmine and build other types of video

monitoring systems. A monitoring point can be a fixed camera, a handset, or a

vehicle-mounted station. Therefore, video monitoring can be performed in various scenarios

in coalmines.

Typically, monitoring points of a coalmine are located on the monitoring of full-mechanized

mining faces, transportation roadways, excavation faces, main roadways, transformer houses,

air well entrances, main slope entrances, auxiliary slope entrances, and other areas. (Change

the description according to an actual project.)

Data Access for the Coalmine Monitoring System

A coalmine monitoring system is functionally divided into a coalmine safety monitoring

system, a coalmine gas extraction monitoring system, a coalmine rail haulage monitoring

system, a coalmine belt haulage monitoring system, a coalmine power supply monitoring system, a coalmine draining monitoring system, a coalmine fire monitoring system, a coalmine pressure monitoring system, a coal and gas outburst monitoring system, and a

personnel positioning system. (You are advised to add, delete, or change the functional

systems of a coalmine monitoring system for an actual project.)

The coalmine monitoring signals are transmitted through wired networks. Due to complex

underground environment, transmission cables are often subject to frequent damages, and

cable routing and network maintenance are often demanding tasks.

With the eLTE wireless broadband trunking network solution, wireless highways are available,

with a transmission capacity of 100 Mbit/s in the uplink and 50 Mbit/s in the uplink per cell.

This solution also supports integration with the existing wired monitoring and control

systems.

Figure 3-4 Data access diagram for an eLTE wireless monitoring and control network for XXX

coalmine

The CPE serves a data access device for the eLTE wireless broadband trunking network and

can connect to the existing coalmine monitoring systems through WLAN, Ethernet, RS485,

and RS232 interfaces. The CPE sends monitoring and control data to the dispatching center

through the eLTE wireless trunking network, and then the dispatching center delivers the data

to various monitoring and control servers through the IP transmission network.

The following describes the functions of major equipment of the coalmine monitoring and

control system:

The analogue sensor converts the measured factors, such as temperature and humidity, into

electrical signals.

The acousto-optic display actuator coverts the control signals to the control physical factors

for acoustic and optical alarms.

The substation receives signals from the sensors and transmits them to the CPE with the

configured access mode (RS485 or Ethernet). At the same time, it also receives control signals

from the monitoring and control servers.

Explosion-proof Designs

Monitoring cameras for underground uses also need to be complied with the customer's

explosion proof requirements, in addition to the terminals and RRUs as described above.

3.2.4 Video Dispatching System

Figure 3-5 Video Dispatching System

eLTE dedicated wireless broadband network solutions that can support mobile monitoring

points (including handheld units, vehicle units, individual systems, etc.) and fixed monitoring

points (with the camera and CPE), provide real-time live video backhaul.

A typical business process of visual command with mobile monitoring points is described

below.

When an emergency occurs, the on-site emergency personnel can use mobile monitoring

equipment such as handset, vehicle units to capture real-time video, send these video via Base

station to center.

Through the core network and the dispatcher, the dispatcher can choose desired live video

information displayed on a large screen of command center. A large screen can display

multiple video images simultaneously.

Staffs in dispatching center can share the situation information on big screen, and be able to

make more accurate and effective decision-making and response;

Staffs in dispatching center can timely send instructions to the scene rescue personnel with

dispatch microphone or Point to Point call, and meanwhile video backhaul services can be

unaffected.

Operators in dispatching center can dispatch live video of desired field to a terminal of

commander, so he/she can know about the specific circumstances of the accident site and

coordinate relative internal resources for emergency rescue.

By the above workflow, oil security sector can truly achieve "visual dispatching", and

effectively improve the security department of the emergency handling ability and

decision-making ability.

3.2.7 Personnel and Vehicle Positioning System

Terminal Positioning Designs

GPS-supporting handset and onboard terminals can be used to implement personnel and

vehicle positioning. Besides, these terminals also report their positions to the GPS servers on

a regular basis.

The GPS servers can also use an electronic map to position the handsets and display the status,

locations, and directions of the handsets. At the same time, the engineer can also choose a

handset on the GPS server through the electronic map and make it to upload and distribute monitoring videos. In addition, the locations of fixed monitoring cameras can also be marked

eLTE Technical Proposal for XXX Project 3 Technical Proposal

20

on the electronic map. Users can search a monitoring camera through the electronic map and

view the monitoring pictures of the camera on the handsets.

A handset enables or disables GPS positioning according to the instructions from the

dispatching console.

The handset uses icons to indicate the status of the GPS positioning function.

The handset supports event-triggered GPS information reporting. Such event includes

terminal fall-down, an emergency call, and low batteries. In case of such an event, the

terminal automatically enables GPS positioning without needing an instruction from the

server. Users configure the events on the server that can trigger a GPS information reporting.

If the handset fails to search for GPS satellite signals or experiences other faults, it gives

the corresponding notification to users without interrupting user operations and sends the fault information to the dispatching console.

GIS Function Designs

The GIS system supports common functions of a GIS system and integration with the video

dispatching system. The functions of a GIS system are as follows:

Supports displays of three types of status of a handset on an electronic map: GPS

information reporting enabled, failed GPS satellite signal searching, and GPS information reporting disabled.

Supports display of the last position update and the update time on the electronic map if

a handset fails to search GPS satellite signals or disables the GPS function.

Supports handset positioning and displays of status, location, and direction of the mobile

terminal on the electronic map. In addition, the GIS system also supports cross-boundary alarm reporting.

Supports association with other functions, which allows users to choose a handset

through the electronic map to start a video monitoring task, to upload and distribute

monitoring videos, to start a point-to-point video call or point-to-point voice call with the chosen terminal, and to send an SMS message to the terminal.

Supports manual configuration or import of GPS information if a device, for example, as fixed camera, is not equipped with a GPS module.

Supports displays of locations of fixed cameras on the electronic map and allows users to

choose and configure a fixed camera and view the monitoring pictures of the fixed camera.

Supports layer control for the electronic map and therefore allows users to choose objects to the displayed on the electronic map.

3.3 Network Designing The LTE standardized eLTE wireless broadband trunking network solution allows various

multimedia communication services on a single network. Such services can be specialized

voice trunking services, broadband data transmission, high-definition video monitoring and

dispatching, personnel and vehicle positioning, and many others. This solution also boasts

sound technological advantages in terms of security, reliability, and extendability and huge

application potentials in the energy fields.

3.3.1 Frequency Designing

The frequencies used for the eLTE wireless broadband trunking network for XXX coalmine

are as follows:

List the frequencies based on the site survey report.

3.3.2 Coverage Designing

The following is an example of a coverage design. You are required to provide the coverage

schemes based on an actual project.

For ground coverage, common coverage solutions for outdoor scenarios apply. The

underground coalmine area features curved and cornered tunnels that hugely hinder free

propagation of radio waves. This makes coverage designing a greatly demanding task and

pushes up network construction costs. Therefore, underground coverage for coalmines is

implemented by leaky cables, rather than antennas. The eLTE wireless broadband trunking

network also adopts leaky cables that are deployed for the existing systems to implement

coverage in underground areas for the coalmine.

Specifically, this solution covers an eBBU and multiple eRRUs. The eBBU is deployed in the

weak-current equipment room, and the eRRUs are deployed close to the leaky cables and

connected to other systems through combiners. The radio signals of the eRRUs travel along

the leaky cables and thereby covers the underground areas of the coalmine. In the interest of

radio coverage in a wide-spreading area, multiple eRRUs are used in this area and signals of

different frequencies in different zones are combined through a combiner. The combiners are

also deployed close the leaky cables. Both eRRUs and combiners are compliant with IP65.

5 Solution Highlights

5.1 High Throughput

eLTE system is designed and developed based on the proven advantage LTE technology. It

provides highly reliable wireless broadband data access with theoretically peak data

throughput of 100Mbps downlink and 50Mbps uplink in 20MHz bandwidth.

Inherently, the uplink/downlink bandwidth can be configured upon scenarios. This offers

flexible solutions for industrial users, where the uplink multi-stream video transmission is

always a crucial demand.

eLTE solution is capable of improving user’s performance even in the cell edge area due to

various of anti-interference algorithms. Especially for situations like high background noise

and interference from both intra and inter frequency networks. By adaptive allocate the

wireless resources with optimization, eLTE solution maximize the spectral efficiency and

maitain a good performance for all users in the cell.

The eLTE solution boasts high system throughput: a single cell allows concurrent

transmission of 16 channels of high-definition videos. This provides reliable real-time

multi-site video monitoring for high-risk places for coalmine enterprises to ensure mining

safety.

5.2 One Single Network for fix telephone and wireless telephone

The eLTE solution supports professional voice trunking services, video monitoring and

control services, and personnel and vehicle positioning services on one single network. This

helps coalmine enterprises to well address issues of high network construction costs and

difficult site acquisitions for multi-network solutions.

5.3 Dedicated Handsets The eLTE terminal supports professional voice trunking, video dispatching, broadband access,

SMS and MMS message, and positioning. Those features are industry leading and can better

meet the requirements of enterprise customers.

eLTE Technical Proposal for XXX Project 5 Solution Highlights

Issue 01 (2013-07-02) Huawei Proprietary and Confidential

Copyright © Huawei Technologies Co., Ltd.

70

The eLTE can still work properly under varying severe conditions, which helps better address

the requirements of enterprise customers. For example, the eLTE terminal, made to IP67

standards, can still work as normal when immersed in 1 m deep water for 30 minutes. The

eLTE terminal is also in conformity with the strictest military standards in the aspects of

collision protection, bouncing protection, and solar radiation protection.

The eLTE terminal also adopts sophisticated noise reduction designs to deliver high quality of

speeches against strong environmental noises.

5.4 Delay-free Mobile Calling Experience

The eLTE solution adopts a variety of innovative technologies to support complete sets of

professional voice trunking functions with industry-leading performance: The group setup

delay is less than 300 ms, the floor application/preemption delay is less than 150 ms, and a

single cell supports concurrent transmission for 160 groups. This well ensures timely delivery

of evacuation notice and broadcasting in case of an emergency.

5.5 High-precision Personnel and Vehicle Positioning

The eLTE solution supports positioning based on terminal GPS information reporting and

visualized GIS systems. This delivers the capability of high-precision personnel and vehicle

positioning and poses the best guarantee for sound rescue efforts in case of an emergency.

5.6 Three-Level Protection Design to Guarantee eLTE Disaster Recovery Capability

To protect the communication network against damage caused by accidents beyond control,

for example, in case of a fire, an earthquake, and floods, the eLTE wireless broadband

trunking solution provides three levels of protections to keep alive the functions of wireless

communication. The eLTE three-level protections include isolated site operation (ISO),

terminal DMO, and emergency communication vehicle (ECV).

If the core network is experiencing a fault or the transmission between the core network and

the eNodeB is interrupted, the eNodeB automatically enters the ISO mode. This ensures that

users served by the eNodeB can still have voice trunking services. Once the fault is cleared,

the eNodeB automatically restores to the normal operating mode.

If the eNodeB serving certain terminals is experiencing a fault, the terminals automatically

enter the terminal DMO mode and can continue to have voice trunking communication with

other terminals within a certain distance.

If the network is made unavailable caused by damages of a beyond-control accident, an eLTE

ECV can be used to set up a temporary eLTE communication to ensure flexible emergency

communication.

5.7 High-reliability Networks to Adapt to Harsh Environment

The equipment of the eLTE wireless broadband trunking solution is developed on hardware

platforms for developing equipment for general LTE networks, and has shown sound

sustainability in the process of long-term high-temperature operation tests conducted in India

and high-cold operation tests conducted in Canada.

To mitigate the damage against the eLTE network caused by accidents beyond controls,

backup designs are adopted for all the eLTE equipment and hot backup for all the boards that

carry essential services. If a module is experiencing a fault, the backup module can

immediately resume the services carried by the faulty module.

The core network is the core of the eLTE network and therefore is rendered with even higher

reliability through hot backup and resource pool technologies. If a process of the core network

equipment enters a fault or error state, the backup process is automatically wakened up to take

over the faulty one. In this way, service interruptions can be prevented. If a board of the core

network equipment is faulty, the hot backup board can immediately play its functions to

resume the affected services.
