4.2.1.4.7. Deactivating complex tracking
CC MTT
The complex tracking deactivation command is sent by a Control Centre to make the receiving Mobile
Telematics Terminal deactivate a tracking process created with the complex tracking request command
described above, ?TRG.
A process with any tracking trigger can be deactivated. The command can also be used for deactivating
all complex tracking processes at once; for this, trigger type 99 can be used.
A tracking process created with either of the simple tracking requests (cf. sections 4.2.1.1 and 4.2.1.2)
cannot be deactivated with this command. For information on deactivating such a process, cf. section
4.2.1.3.

Reception
Upon receiving a complex tracking deactivation command, the receiving instrument should stop the
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.
