Abstract

In trunked radio control systems management dis- patchers may regroup one or more radios to dynamic T&groups or Subfleets to allow communication between radio operators that would not normally belong to the pre-coded groups available on the selectors on the radio units, as need arises. This feature is utilized to coordi- nate activities of subscriber groups that would not nor- mdly have a need to communicate, for instance police car fleets in neighboring counties. Upon acknowledging a Regroup command, a radio unit will ignore the cur- rent setting of its Talkgroup Selector and move to the Talkgroup specified in the command (the Target Talkgroup).
