Principles (1/5)

• Automatic Vehicle Location (AVL)– Provides the position of selected

units in real time

• Adaptive position updates based on moved distance or time interval

• Geographical Information System (GIS) at Command and Control room and/or at the vehicles

Principles (3/5)

3. Radio Network 4. Location server

3.Radio network• Efficient mechanisms to control load

of the AVL updates and other data messages

• An Application Programming Interface (API) for Location Server and other applications

4.Location server• Decodes LIP format location updates• Collects and stores the latest position

data of the traced radio terminals in the network

• Provides interface for the authorized AVL client applications to access location information of the radio terminals based on the definitions in the network

• Manages the parameters of position updates for each organization

TCS Server(3 pcs) interface

•AVL support in the radio network

interface

5.AVL client applications• Show real time location of the

field forces on top of the map on screen

• The resolution of the provided digital map is 1:100 000

• The resolution of the layer is 1:5 000 for 28 Regional Centers

The interface enables• easy integration of customized AVL

applications• multi-vendor market for the AVL

applications• time and changed position based as

well as immediate location requests• one logical address to access for any

subscribers’ location data

•AVL Client Applications in Control Rooms and Offices

Principles (5/5)

• One Location Server / TETRA network• The centralized Location Server provides location and tracking

data of all subscribers in the network for large number of the AVL Client Applications

• Location Server collects location data through the distributed TCS Servers

control rooms and offices

•Centralized AVL topology

• Architecture

• AVL system architecture & data flows

The configuration is a mono-site AVL server configuration with redundant server and database, associated to a web-based AVL Display composed of an AVL Display server and several Display clients.

AVL server is connected to 3 TCS Servers: a primary cluster of 2 TCS on DXT1 and a secondary TCS on DXT2.

Architecture (1/2)

Architecture (2/2)

• Fire Brigade Main Sites– Requirements on Data

flows between :

> TCS AVL Server

> AVL Server AVL Display server

> AVL Display Server AVL Display Clients

• Components

• The AVL sub-system is composed of : – – 1 AVL Server Cluster

Components (1/3)

– – 1 AVL Display Cluster

Components (2/3)

• 29 AVL Clients• Dual screen web-based light clients

Components (3/3)

- 1 with two 57" TFT LCD monitors

- 28 with two 21" TFT LCD monitors

• Features

• Resource management :

– AVL operator manages resources

• Units (HH or Vehicles)

• Fleet (based on TETRA Organisation blocks and sub-blocks)

– Flexible management of access rights

• From Administration / Supervision level of AVL Display Server

• From TETRA network (Organisation level)

– Customisation of application via profiles saving :

• map views

• tracked units

Features (1/5)

Map view – Tracked resources are identified (icon / name)

– Operational status displayed through a colour code

Features (2/5)

-Clicking on a tracked unit, the operator can :

-Command the configuration parameters for tracking the resource (Maximum reporting interval, Maximum distance interval)

-Get radio state of the resource

-Change manually the operational status of the resource

-Access to instant Replay

-Open a new map view or modify the current map view which will be centred on this resource

-Get the configuration data of this resource

– Selection of different kind of maps (raster, vector, satellites).

– Map layers are switched on or off automatically on basis of zoom level.

– The AVL application allows to define some specific layers (Points of Interest such as hydrants or incident address).

Features (3/5)

• List view – Operator has the possibility to focus on a set of resources

in a permanent or temporary list :

Features (4/5)

• Geo-fencing – Operator has the possibility, for each resource, to draw restriction zones

Features (5/5)

Alarms are generated in

case of violation of

exclusion or inclusion rules

• Configuration

Configuration (1/5)• IP Addressing plan

– DXT sites• Sofia

– OMU Subnet– SIPU Subnet

• Burgas– TCS Subnet

– AVL Server / AVL Display Server site– AVL Clients sites

Configuration (3/5)

• TETRA BACKBONE Dimensioning :

–The following figures give an

estimate of dataflow related to

AVL service, assuming 1000

Radio terminal with activated

location feature registered in the

network and a polling period of 90

seconds, (I.e.: 11 locations per

second.)

Configuration (4/5)• IP Backbone dimensioning

– IP traffic between TCS server and AVL server
