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.
