Huawei eLTE Trunking Features

Today’s communication landscape is changing quickly. Voice communications alone cannot satisfy enterprise

requirements for staff interaction and information sharing, and data services are increasingly critical for

meeting strategic objectives.

Emergency response and public safety: � A single network with advanced technology providing both

traditional Private Mobile Radio (PMR) and broadband services, including images, data, and video, speeds

responses and saves lives.

Metro: � With the development of the metro industry, operators need faster, more efficient, and safer

travel, and passengers expect a more comfortable trip. Train-to-ground broadband networks providing

Closed Circuit Television (CCTV), Wi-Fi, Passenger Information System (PIS), and a Communication-Based

Train Control System (CBTC) carrier have become imperative.

Airport authorities and port areas: � Guaranteeing the quality of ground or yard services and minimizing

delays, through the delivery of simultaneous voice, data, and video, are urgently required to reduce

operating costs.

Other industries: � In oil and gas, the smart grid, and mining, smart data terminals are often dispersed

in remote areas where real-time wireless data acquisition and on-site video are more convenient and

effective than wired technology to ensure staff and product safety.

The Huawei eLTE solution is based on advanced LTE technology to provide professional broadband trunking,

data, video surveillance, and other broadband services on a single network with 100 Mbit/s throughput and

low-latency transmission. It enhances operational efficiency and safety and opens up a variety of services not

previously available.

The Huawei eLTE broadband trunking solution is based on the most-advanced LTE technology, to provide

professional services for enterprise, such as broadband trunking, video surveillance, data acquisition,

broadband data access, emergency communications, and other broadband services on a single network.

Enhanced Voice Dispatching Services

Group call is point-to-multipoint call between a

UE and multiple independent dispatching consoles

which enables a UE or a dispatching console to

establish point-to-multipoint calls.

Broadcast call is a point-to-multipoint (P2MP) call

initiated by the dispatching console only and the

floor can’t be preempted. Broadcast group calls

include network-wide broadcast groups and area-

specific broadcast groups. All UEs in a specified

area can receive broadcast calls.

Private calls (P2P calls) in full-duplex mode are

enabled between trunking users, between

trunking users and dispatching console users, or

between dispatching users. Private calls are in

point-to-point full-duplex mode, which ensures

that only the two parties in a private call can

hear each other.

Emergency calls have the highest priority. With

this feature, information is reported to predefined

users promptly in emergency. User can press the

emergency call button on top of a terminal to

start an emergency call without dialing or pressing

the PTT button.

DMO is a supplementary function and can be

used for communication when an area has no

LTE signal. In DMO mode, a user can talk to

other users on the same frequency after pressing

the PTT button on the UE. When the speaker is

talking, other users cannot preempt the floor.

After the floor is released, other users can press

the PTT to talk.

DMO

DMO

This basic feature enables UEs to preempt the

floor based on their priorities after a group call is

set up. When a UE applies for the floor but the

speaker already exists, the dispatching system

compares the priority of the UE applying for the

floor with that of the speaker.

If the speaker has a lower priority, the dispatching

system releases the floor and allocates it to the UE

applying for the floor. If the speaker has a higher

priority, the dispatching system does not release

the floor. During the floor release, the UL voice

resources of the former speaker are also released.

The former speaker then becomes a listener.

Videos can be transmitted to the dispatching

console from the handset terminal through a

backhaul over the LTE wireless network. Both the

dispatching console and handset terminal can

initiate video upload, and sound can be enabled

or disabled based on customer requirements.

The dispatching console also can send one line of

video to one or multiple specified terminals. The

user can play the received video and choose to

enable or disable sound.

In hierarchical mode, one dispatcher serves as

the upper-level dispatcher and other dispatchers

serve as lower-level dispatchers. Voice or video

service exchanged between two lower-level UEs

served in different lower-level dispatchers must be

transferred through the upper-level dispatcher.

eNodeB sharing refers to the RAN partially or fully

shared by multiple private network CNs.

With this feature, carrier and base station

resources are shared by operators, overcoming

the difficulty in applying for frequencies and

saving the investment cost. In addition, these

operators run their own independent service to

isolate service data. For example, production data

and management data can be isolated in the

electric power industry.

Security

End-to-End Encryption can encrypt PTT voice

stream, private call voice stream and short

message to prevent eavesdropping on the sensitive

communication. The terminal that supports E2E

encryption should be equipped with a TF encipher

card, which be authenticated by the KDC. When

initiating an enciphered call, a caller obtains a

session key from the KDC through the eAFE, and

the KDC distributes the session key to the callee.

The caller will encipher the voice stream by the

TF module, and the callee will decipher the voice

steam with the same session key. The network

only transmits the stream that can’t be decrypted.

Fallback mode allows the eNodeB disconnected

from the CN to support basic functions of PTP

calls and group calls within its coverage area to

improve system reliability.

Fallback Mode

Reliability

This feature implements NE-level 1+1 cold

redundancy of CNs by reuse the S1-flex load

balancing algorithm in case of regional disasters.

The active and standby NEs will periodically check

the status of each other using handshaking. If

handshaking is normal, each NE considers that the

peer NE is normal. If the active NE becomes faulty,

the standby NE detects the fault by heartbeat

detection, and switches to the active state within

3 minutes.

CN Geographical Redundancy

If an LBBP is faulty or its resources are insufficient,

the cell served by the LBBP can’t be dynamically

reestablished on the LBBP. With inter-LBBP

redundancy, the cell can be reestablished on

another LBBP with available resources or on a

backup LBBP. In this way, services in the cell can

automatically recover and service interruption

duration is reduced.

The eCNS, eSCN, and eNodeB support bearer-level QoS control to ensure end-to-end (E2E) QoS in eLTE network. The QoS Management

feature involves radio resource processing over the air interface, and provides dynamic scheduling, semi-persistent scheduling, and adaptive

modulation and coding (AMC). The QoS Management feature can guarantee QoS for GBR(Guaranteed Bit Rate) and non-GBR services and

achieve an optimal tradeoff among throughput, fairness, and QoS.
