AVL Client
Applications
• Automatic Vehicle Location (AVL)
– Provides the position of selected
units in real time
• Adaptive position updates based on
moved distance or time interval

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

Typical AVL client
applications in the control
rooms and offices
• 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

Architecture (1/2)
• 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.

• Components
Components (1/3)
• The AVL sub-system is composed of :
–
– 1 AVL Server Cluster
Components (2/3)
–
– 1 AVL Display Cluster
Components (3/3)
• 29 AVL Clients
• Dual screen web-based light clients
- 1 with two 57" TFT LCD monitors
- 28 with two 21" TFT LCD monitors
• Features
Features (1/5)
• Resource management :
– AVL operator manages resources
• Units (HH or Vehicles)
• Fleet (based on TETRA Organisation blocks and subblocks)
– 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 (2/5)
Map view
– Tracked resources are identified (icon / name)
– Operational status displayed through a colour code
-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
Features (3/5)
– 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 (4/5)
• List view
– Operator has the possibility to focus on a set of resources
in a permanent or temporary list :
Features (5/5)
• Geo-fencing
– Operator has the possibility, for each resource, to draw restriction zones
Alarms are generated in
case of violation of
exclusion or inclusion rules

• 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.)

• IP Backbone dimensioning
– IP traffic between TCS server and AVL server
•
– IP traffic between AVL server and AVL Display
server
•
– IP traffic between AVL Display server and AVL
