Introduction to RNC Software

RNC Software runs on top of 3 different Operating

Systems namely DMX,Chorus & OSE.

SW is separated into

ATM Platform SW.

RNC Application SW.

RNC Application SW is included into one System BlockRNQSYB

R4ASEB. Resources for Application level Service Block

NRMPRB

Transport Resource Manager for transport resource reservation,

modification and releasing in application level in RNC.

Runs in ICSU over DMX

BIFPRB

Allocates Binding Ids for Iur Control Plane Signalling (RNSAP)



12/23

Different Service BlocksL3TSEB. Responsible for handling Layer 3 Protocols signalling.

RRCPRB

Runs in ICSU over DMX Provides signalling connection towards MS and Call control

functionality

Divided into four parts

MCC (MS Connection Control). Controls connection between MS, RNC and CN.

Requests capacity from RRM, produces TrCh & RLC parameters.

One MCC hand per MS in RNC.


13/23

Different Service BlocksMCC In DRNC,MCC hand exists but does not have RRC connection.

RRC-C handles the RACH/FACH signaling towards the MS when there is no RRCconnection. There will be one RRC-C per cell and it is created when

RACH/FACH is created.

RRC-D

handles the signaling procedures when the mobile has RRC connection.There will be one RRC-D per MS in RNC and it is created every time MSmakes the connection establishment and it is released when connection isreleased


14/23


RRC-S

Handles the system info scheduling, segmentation and broadcasting. There

will be one RRC-S per cell created at the time of RACH/FACH creation.

NBAP PRB

Runs in ICSU over DMX & provides signalling conns to BTS.

Divided into two parts

NBAP-C. Offers common procedures of NBAP towards BTS. One NBAP-C per BTS. NBAP-D. Offers Dedicated procedures of NBAP towards BTS. There will be One NBAP-

D per Traffic Termination point in BTS.


15/23

Different Service BlocksIURPRB Offers signalling connections between RNCs and handles RNSAP

procedures. Runs in ICSU over DMX.

One IUR hand per MS per Neighbour RNC.

IUVPRB Offers signalling connections towards CN and handles RANAP

procedures.

Runs in ICSU over DMX.

One IUV hand per MS per CN.


16/23


RC3PRB

Centralized part of Telecom signalling

Located in RRMU

Maintains PIDs, state changes of subsystems, UL Scrambling codes

for MS Connections.

Takes care of Resource Releasing due to Fault situations.


17/23


RRUSEB. Consists of two PRBs

BRMPRB. Base Station Resource Manager.

Offers cell specific control of radio resources for telecom purposes.

Runs in ICSU over DMX.

Main functionality includes Admission Control, Packet Scheduler, Load

Control and Resource Manager.

One BRM Hand per BTS.


18/23


HA3PRB. Main purpose is to achieve mobility management

in Radio Access Network.


One HA3 hand per MS in RNC.

Supports different types of handovers.

Handles handover related measurements.
