3.2.6 Dynamic Group Number Assignment (DGNA)
DGNA allows your service provider or authorized user to dynamically allocate new, or update existing talkgroups
to your radio over the air interface. Using supplementary services messages (SS-DGNA), the network operator
can command your radio to add talkgroups, update the existing talkgroups, or delete talkgroups from the list. This
operation is performed by transmitting the data to your radio.
