    HI friends,

    This is Rehan from India …I Need some information about the call flow in CDMA network in case of Data Calls…Connectivity to PDSN,MSC,PCf ..Signalling details between these nodes .
    I would be thankful if any of you provide me an overview on this

    The PCF, Packet Control Function, provides RLP, (Radio Link Protocol) termination from the Data Capable Mobiles. In turn, the PCF sets up a R-P tunnel, (Radio-Packet) to the PDSN(Packet Data Serving Node) for A10/A11 traffic. Typically, the PCFs would have a PDSN file to which the mobile can hash to. The PDSNs authenticate the mobile via a AAA server that has profiles set for each mobile(includes the MIN/ESN of the mobile). The PDSN needs to be provisioned with the IP address of the PCFs..

    The MSC(SM/PSU) handles all RLP traffic from the cell from which the call originates in the form of F.Relay SVCs to the PCFs(Sun Servers with T1 interface cards).

    This was an overview & hope it helps.
