Abstract
A broadcast method for simultaneously switching an announcement to a plurality of subscribers of a communication system is provided. Given announcements that are to be disseminated according to the broadcast method of the invention, a call should be switched such that a subscriber hears the announcement from the beginning. In order to meet this demand, call requests for an announcement are inventively collected and are simultaneously through-connected after the expiration of the collecting time.
