ABSTRACT:
Four stages of digital cellular architecture are presented which reuse much of the existing voice infrastructure while allowing graceful introduction of data and integrated voice/data services over industry standard, low cost platforms. First, a separate ATM-based infrastructure is introduced that supports data services. A new data call control is introduced on industry standard hardware platforms using object oriented and modular programming. Second, ATM is introduced at radio ports and call control functions are migrated to the new ATM-based call control platforms. Third, vocoders are introduced at the DCS. Fourth, the cellular functions of the legacy cellular switch are phased out and replaced by the ATM-based target architecture.
