摘要

Method and apparatus for updating a subscriber unit with an announcement group identification. A subscriber unit (210) requests affiliation (301) with a talk group (202) and an unknown announcement group identification is issued (315) in response to the request for affiliation. The present invention includes an embodiment where information that identifies which subscriber unit (210) received the unknown announcement group signal is stored (309). An updated announcement signal is subsequently sent to the subscriber unit (210) when a zone controller (114) receives an updated announcement group identification.
