4.2.1.5.2. Deactivating real time complex tracking
CC MTT
The real time complex tracking deactivation command is sent by a Control Centre to make the receiving
Mobile Telematics Terminal deactivate a tracking process created with the real time complex tracking
request command described above, ?TRR.
A process with any tracking trigger can be deactivated. The command can also be used for deactivating
all real time complex tracking processes at once; for this, trigger type 99 can be used.

Reception
Upon receiving a complex tracking deactivation command, the receiving instrument should stop the real
time tracking process with the trigger type specified in the request. The process is totally deactivated, so it
will not be restarted again even if its start trigger condition is met again. Specifying trigger type 99
deactivates all complex tracking processes at once.
Depending on the authorization of the Control Centre which requested the stopping, the tracking process
may be stopped at once or the request may be disregarded altogether. Cf. section 2.1.3 for more
information.
