Abstract
A radio communication system supports talk group communication and multi-group communication. Upon initiating a multi-group communication, the system causes any active talk group speakers in the talk groups included in the multi-group to dekey by changing the identifier in a monitored control channel of the talk group from the identifier of the present talk group speaker to a different value.
