Service Processing Subsystem Introduction


30/80


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

Message tracing

Radio Access Network (RAN) information management

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.
