Making the Transceiver Migrate to a Particular Talkgroup
(Dynamic Regrouping)
Dynamic Regrouping
is the function by which a dispatcher in the RFSS makes the transceiver migrate to a particular
Talkgroup. By using an air message from the system, a dispatcher can form a Talkgroup as desired. Also, changing the
transceiver Talkgroup by a user can be prohibited if necessary. These functions are operated by a dispatcher, but a Regroup
request from a user is also available.
The following figure shows the usage of Dynamic Regrouping. This is a diagram showing how the dispatcher selects multiple
transceivers (transceivers enclosed with dotted lines in the following figure) on a PC application, and regroups registered
Talkgroups (TG 1 to TG 4) to TG 5.

Configuring the Dynamic Regrouping
The following functions related to Dynamic Regrouping can be configured by using KPG-D1/ D1N:
0
Dynamic Regrouping
Dynamic Regrouping can be enabled or disabled. To use Dynamic Regrouping, the function needs to be enabled in each
P25 Trunking system.
0
Dynamic Regrouping Zone - Channel
One Zone-channel used for Dynamic Regrouping can be assigned to each P25 Trunking system. If the transceiver
receives a Dynamic Regrouping command from a system, the transceiver migrates to the Zone-channel configured with
this function.
0
Dynamic Talkgroup (Multi-key List No.)
The Encryption Key used for changing a Talkgroup using Dynamic Regrouping can be configured. To execute Secure
transmission using a regrouped Talkgroup, the “Scrambler/ Encryption” function needs to be assigned to one of the keys.
If “Scrambler/ Encryption” is not assigned to any key on the transceiver, the transceiver only sends a Clear transmission.
