2.2. Applications
MPTP provides a wide set of commands for realising the application examples listed in chapter 1. The
commands can be categorised according to their type as is done below; this categorisation will be used
throughout this document. It should be noted that all report commands typically contain the sending
instrument’s position information.
2.2.1. Position reporting
The simplest method of sharing the position information of a Mobile Telematics Terminal is by using
positioning commands. Typical positioning scenarios are as follows:
1. A Control Centre wants to know the position of a Mobile Telematics Terminal.
Examples: (1) A parent wants to know the whereabouts of her child. (2) The shift manager of
a taxi company wants to know the position of a car in the field.
The centre sends a position request MPTP command to the terminal. The terminal then
responds by sending a position report MPTP command which contains its position
information.
2. A Mobile Telematics Terminal wants to inform a Control Centre of its position.
Example: A security guard informs the alarm centre of his position before entering a
dangerous area.
The terminal sends a position report MPTP command to the centre.
3. A Control Centre wants to know where a Mobile Telematics Terminal has been.
Examples: (1) A probation officer wants to know where the offender has been moving lately.
(2) A hunter wants to know where his dog has been moving while chasing a deer.
The centre sends a position history request MPTP command to the terminal. The terminal
then responds by sending a position history report MPTP command, which contains the
requested number of known positions with times.
