    Functions of Service Processing Subsystem

    The RNC service processing subsystem implements most RNC functions

    defined in the 3GPP protocols and processes services of the RNC.

    User data transfer

    System admission control

    Radio channel ciphering and deciphering

    Integrity protection

    Mobility management

    Radio resource management and control

    Multimedia broadcast

    Components of Service Processing Subsystem

    TheRNCserviceprocessingsubsystemconsistsofthesignaling

    processingunit(SPUa),anddataprocessingunit(DPUb).

    An SPUa board has four independent subsystems. Each subrack has a

    Main Processing Unit (MPU) subsystem for the management of resources

    on the user plane and resource allocation during a call. The other

    subsystems work as Signaling Process Unit (SPU) subsystems, whichprocess signaling messages on the Iu, Iur, Iub, and Uu interfaces.

    A DPUb board has 22 Digital Signal Processors (DSPs). The DPUb

    performs L2 processing on the data sent from the interface board and

    separates CS and PS domain data and Uu signaling messages.

    In the RNC, the SPU subsystems work as a control plane resource pool;

    the DSPs work as a user plane resource pool.

    Loaded with different software, the SPUa board is functionally divided into

    the controlling SPUa board and non-controlling SPUa board.

    The controlling SPUa board is used to manage the user panel resources within this

    subrack.

    The non-controlling SPUa board is used to handle the signaling processing.
