Hunt
In the DMR system, the radio terminal is required to register with a base station for
normal operation. Before registering, the terminal will hunt (search) through the
control channels for available base stations. The system provides multiple hunt
policies for the registered terminals to ensure normal communications.
The Last Registered List saves the last 10 control channels on which the radio has
worked prior to power-off.
Note: The Last Registered List cannot be viewed on the UI because it runs in the
background.
Short Hunt
The radio will hunt for the last 10 control channels on which it has worked. If the radio
fails to register on all the 10 channels, it will go on with the Fixed TSCC List. The hunt
process will cycle until the radio successfully registers with a base station.
Comprehensive Hunt
Short hunt would be performed preferentially. If short hunt brings no successful
registration, comprehensive hunt will go from the minimum channel up to the
maximum channel defined in the FPP. Every 100 channels are hunted during
comprehensive hunt, the previously said 10 channels will be hunted again. If no
successful registration is achieved after comprehensive hunt, the hunt will go on with
the Fixed TSCC List. The hunt process will cycle until the radio successfully registers
with a base station.
Team Hunt
The radio will hunt for the last 10 control channels on which it has worked. If the radio
fails to register on all the 10 channels, it will go on to hunt the channel team available
in the Team Hunt List. The hunt process will cycle until the radio successfully registers
with a base station.
