Abstract
Abstract A method of registration in a communication system includes the steps of detecting (201) an elevated registration level of at least a part of a communication system, selecting (203) a group recovery time, determining (205) a first random registration time that is less than or equal to the group recovery time, registering (209) a first communication unit (111) from a first talkgroup at the first random registration time, and upon receiving (212) a group activity message for the first talkgroup, delaying (213) registration by at least a second communication unit (113) from the first talkgroup.
