MPTP | MPTP commands 9
The MPTP commands, which can be used for realisation of these scenarios, are described in section 4.1.
2.2.2. Tracking
The term tracking means a function, which enables monitoring a target’s position and possible movement.
The tracked Mobile Telematics Terminal will automatically send a series of MPTP messages of its position
to the Control Centre as defined by the tracking process. Typical tracking scenarios are as follows:
1. A Control Centre wants to follow the movements of a Mobile Telematics Terminal.
Examples: (1) A delivery company wants to monitor the movements of a valuable transport.
(2) A hunter wants to know how his dog moves in the forest.
The centre sends a tracking request MPTP command to the terminal, requesting the
terminal to send tracking report MPTP commands at regular intervals. The centre can
specify the number of reports it wants to be sent, or it can set a duration or end time for the
tracking process. Setting timing for a single report is also possible.
2. A Control Centre wants to be informed when a Mobile Telematics Terminal enters or exits an
area.
Examples: (1) An electricity company wants to know when a team of electricians arrives at a
storm damage area and when it departs from there. (2) A parent wants to know when her
child crosses the border of a permitted area.
The centre sends a tracking request MPTP command requesting the terminal to send one or
more tracking report MPTP commands when it enters and/or exits an area. The centre can
specify whether it wants to receive just one report, or get reports at regular intervals while the
target is inside or outside the area.
3. A Control Centre wants to be informed when the speed of a Mobile Telematics Terminal goes
over or under a limit.
Example: A delivery company wants to know when a valuable transport is on the move or
when it stops.
The centre sends a tracking request MPTP command requesting the terminal to send one or
more tracking report MPTP commands when its speed goes over or under the specified
limit.
4. A Mobile Telematics Terminal wants to inform a Control Centre of its movements.
Example: A social worker wants to keep his shift manager knowledgeable about his
movements when entering a dangerous area.
The terminal sends a tracking request MPTP command to the centre, requesting its
permission to start sending tracking reports. The centre can accept or reject the request by
sending an acknowledgement MPTP command. If the request was accepted, the terminal
will start sending tracking report MPTP commands as it declared in its request.
The MPTP commands, which can be used for realisation of these scenarios, are described in section 4.2.
Entering and exiting an area can also be monitored by using the travel mark commands; cf. below.
