SYSTEM AND METHOD FOR USING INTEGRATED SERVICES DIGITAL NETWORKS (ISDN) AND THE CALL APPEARANCE CALL HANDLING (CACH) FEATURE OF ELECTRONIC KEY TELEPHONE SERVICE (EKTS) TECHNOLOGY FOR MOBILE SYSTEMS

摘要

A mobile call processing methodology and concomitantsystem based on ISDN/CACH-EKTS technology which canbroadcast incoming calls to base stations (e.g., 1050)and which uses the ISDN/CACH-EKTS bridging technology tohandle base station handoff of an established call. Eachmobile user (e.g., 1041, 1042) is assigned a unique EKTSdirectory number as well as a unique call appearanceidentifier, which allows for the handling of multiplecall appearances of the unique DN on a single basestation.. For a given mobile communication application,the central office (e.g., 1014) treats the base stationas an ISDN/CACH-EKTS terminal.
