6. R4 Network Architecture
•In R4, MSC is divided to MSS and MGW.
•Call Control (CP) is separated from Bearer Layer (UP)
•Media Gateway Control Protocolsuch as H.248 have been widely used

Hardware architecture (CPCI) Hardware architecture (ATCA)
•Networking is the same.
•Performance of ATCA is much better than CPCI.
•The ATCA platform enables the software to capitalize on the advanced hardware with multiple cores and
multiple CPUs, thus improving the system performance without affecting the reliability.
