4.2.1.1. Simple tracking request: interval, minutes (?TRC)
CC MTT
The simple tracking request command is sent by a Control Centre to make the receiving Mobile
Telematics Terminal create and activate a tracking process with the following properties:
Start trigger : None.
The tracking process is started as soon as it is created.
Interval
The process will send tracking reports at the specified interval until the stop trigger condition is
met. The interval is given in full minutes.
Stop trigger : Number of reports.
The tracking process is stopped when the specified number of reports have been sent.
If the interval needs to be given in seconds, use the command described in section 4.2.1.2 instead. For
more complex tracking processes using different start and stop triggers, the complex tracking request
described in section 4.2.1.4 needs to be used.
