Abstract
A mobile call processing methodology and concomitant system based on ISDN/CACH-EKTS technology which can broadcast incoming calls to base stations (e.g., 1050) and which uses the ISDN/CACH-EKTS bridging technology to handle base station handoff of an established call. Each mobile user (e.g., 1041, 1042) is assigned a unique EKTS directory number as well as a unique call appearance identifier, which allows for the handling of multiple call appearances of the unique DN on a single base station. For a given mobile communication application, the central office (e.g., 1014) treats the base station as an ISDN/CACH-EKTS terminal.
