Abstract
In a method for automatically controlling a call-waiting-interruption restriction for a communication system, a subscriber is supplied with a call-waiting service permitting an interruption processing when an interruption call occurs. The subscriber is also supplied with a call-waiting-interruption restriction service for restricting the interruption processing even when the interruption call occurs. The interruption processing to the second subscriber is automatically restricted, when a first subscriber supplied with the call-waiting-interruption restriction service is in communication with a second subscriber supplied with the call-waiting service.
