    In 2G – GSM Only CircuitSwitching.
    Done by Switching System.

    In 2.5 – GSM+GPRS MSC-Circuit Switching.GPRS Nodes Handles Packet Switching.

    In UMTS- Plan to make evrything as PACKETS.

    In CDMA – 2G uses Ckt Switching.
    In 3G/2.5, it’s packet switched at the air interface for Supplemental channels.

    Hi George:
    in the cdma msc solution,most of the part are ATM based,like handover and mobile to mobile call, so it is a combiner of TDM and ATM system!
