Service Processing Subsystem Introduction


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


Components of Service Processing Subsystem

The RNC service processing subsystem consists of the signaling processin

g unit (SPUa), and data processing unit (DPUb).

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

in Processing Unit (MPU) subsystem for the management of resources on t

he user plane and resource allocation during a call. The other subsystems

work as Signaling Process Unit (SPU) subsystems, which process signalin

g messages on the Iu, Iur, Iub, and Uu interfaces.

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

ms 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; th

e DSPs work as a user plane resource pool.

OMUa Borad

Support two Intel LV processor 、 2G memory

Support three ETH port in front plane （ 10/100/1000M Base-T self-adaptation ），OMU use this network port to connect with the internet directly. It’s more simple com

pared with the IBM server

Support two paths backboard SERDES to the GE port and the host and standby FE

path of the switch board, host and standby OMU 、 OMU and SCU are connected by

this port

OMU supports two hard disk interfaces by using the panel network port , connects wi

th two hard disk outside, and be mirror with each other to Raid 1

On the panel of the OMUa board, there are four USB2.0 ports and one BMC com po

rt （ can used to system com port

The OMUa boards can be installed only in slots 20 and 21, or slots 22 and 23 in the

RSS subrack. one OMUa board occupies two slots

Y-Shaped E1/T1 cable

(1) DB44 connector (2) Main label (Identifying the code, version, and manufacturer information of the cable)

(3) Label (Identifying a coaxial cable)

(4) Metal case of the DB44 connector

E1/T1 cable is used to connect E1/T1/J1 port

The Y-shaped 75-ohm coaxial cable/ 120-ohm coaxial cable used in the RNC

has two DB44 connectors at one end and has a structure of 2 x 8 cores. That is,

the 75-ohm coaxial cable is composed of two cables, each of which contains eight

micro coaxial cables. The 16 micro coaxial cables form eight E1 RX/TX links.


Y-shaped RNC Clock Signal Cable

(1) Label (Identifying a pair of twisted pair cables) (2) RJ45 connector

The RJ45 connector at one end of the Y-shaped RNC clock signal

cable is connected to port CLKIN on the SCUa board. The two RJ45

connectors at the other end of the signal cable are connected to ports

CLKOUT on the active and standby GCUa/GCGa boards which are lo

cated in the RSS subrack.
