4.2.1.4.6. Trigger type 9: anchor tracking

CC → MTT

An anchor tracking process is used for monitoring a Mobile Telematics Terminal’s departure from an

area. The process can be created and activated by a Control Centre, by sending a complex tracking

request command with trigger type 9.

The tracked area is circular. It is defined by a centre point and a radius. The centre point is taken

automatically from the current position of the device. Note that the current position can be old if the

terminal has not been able to update it’s position earlier.

Anchor tracking process is like circle area tracking b ut it will start Emergency proicess instead of

tracking.

An anchor tracking process remains active even after its stop trigger condition has been met. It will be

automatically restarted if the start trigger condition is met again. To deactivate a process so that it will not

start again, use the command described in section 4.2.1.4.7.

Depending on the authorization of the Control Centre which sent the request, a new tracking process may
