Group Regrouping sessions in trunked systems involve combining two or more talkgroups into super groups, allowing members of the different talkgroups to communicate with each other. Normally this opera- tion is transparent to the subscriber user; the main dif- ference is the increased amount of voice activity brought about by having more users involved in dis- patch calls.
