BSC6810 Cabinets

The RNC uses the Huawei N68E-22 cabinet and the Huawei N68-21-N cabinet. The

two models of cabinets have the same appearance.N68E-22 is divided into a single-

door cabinet or a double-door cabinet.

RNC Logical Structure

Logically, the RNC consists of the following subsystems: switching subsystem,

service processing subsystem, transport subsystem, clock synchronizationsubsystem, Operation and Maintenance (OM) subsystem, power subsystem,

and environment monitoring subsystem.

SCUa Board Introduction

Port Name Function PortType

10/100/1000BASE-T011 10M/100M/1000M Ethernet ports. The ports are

used for the inter-subrack connection.

RJ45

COM Serial port for commissioning RJ45

CLKIN

Port for inputting reference clock source. This

port is used to receive the 8 kHz and the 1PPStiming signals from the GCUa/GCGa board.

RJ45

TESTOUT Port for testing timing signal output. This port is

used to test the timing signal output

SMB

Service Processing Subsystem Introduction


27/46


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

Cell broadcast service

Multimedia broadcast

Message tracing

Data volume reporting

Radio Access Network (RAN) information management


28/46


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.
