Abstract
A local switch includes circuitry for determining whether a called party is a subscriber of a call type delivery service when a call is being placed to the called party. The local switch also includes circuitry to generate a message to prompt the calling party to identify whether the call is urgent, normal, or telemarketing. If the calling party does not respond in a timely manner the local switch includes circuitry to analyze the response by the calling party and to generate corresponding signals to inform the called party of the unknown call type. More specifically, either a different ring pattern is generated or a specified symbol is displayed on a display or both to inform the called party of the call type. The present invention may be used in conjunction with modern communication networks such as intelligent networks and public land mobile networks.
