What is DGNA (dynamic group number assignment)?

DGNA gives the capacity for a network administrator or approved client to dynamically allocate new to selected terminals over the air interface. Utilizing supplementary services messages (SS-DGNA), the network administrator can command the terminal to add talkgroups or to update the existing talkgroups. At the point when a DGNA message is received and DGNA warning was designed by the Service Provider, then individuals will get a notice message and afterward show the new tasks.
