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
Typical AVL client applications in the
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
