RNC Object

• The logical object of the Radio Network Controller

• It can have up to 2800 WBTS objects (requires RNC 2600)

• In the RNC object the following interfaces are defined: Iu-PS, Iu-CS & Iur

• The logical object are hierarchically related to each other, therefore it is not possible to create any other object before RNC creation.


WBTS Object

• The logical object of the WCDMA Base Station (Node B). A WBTS can have up to 24 WCDMA cells, 1 COCO and 1 IPNB object.

• If Iub transport QoS is used, WBTS connects to 1 TQM object


WCEL object

• The logical object of the WCDMA Cell is created to define the configuration of the WCDMA Node B site. In 1 RNC database there can be 2800 WCELs.


Handover PathHOPx

• The Handover Path object stores mainly Cell Reselection & Intra-Frequency HHO parameters. One HOPx can be related to several Adjacency objects.

• The maximum number of HOPx objects within 1 category is 100.

• E.g. for different type of cells (urban, rural, macro/micro/pico)

• HOP Types:

• HOPS — object for intra-frequencyHandover Path

• HOPI — object for inter-frequencyHandover Path

• HOPG — object for inter-systemHandover Path

The parameter indicates whether the DSR based SHO is enabled in the cell. When the Detected Set Reporting & Measurements feature (optional) is enabled in the RNC, the parameter can have the following values:0: DSR is not allowed.1: DSR is enabled but SHO to detected cell is not allowed.When the SHO based on the Detected Set Reporting feature (optional) is enabled in the RNC, the parameter can have the following values:0: DSR is not allowed.2: DSR based SHO is enabled.

COCO / IPNB

COCO: Connection Configuration• A new logical COCO object is created in order to reserve local transmission resources for the

WCDMA BTS.

• The COCO objects display the transmission resources in the Iub interface, but not the actual network topology

• There can be up to 400 COCO objects in the RNW database

IPNB: IP Node B

• When IP transport is used on Iub, the IPNB object collects related parameters like:

• IP address of NodeB

• SCTP port numbers of C-NBAP and D-NBAP

• DiffServ Code Points


TQM / WRAB

TQM: Transmission Quality Management• when Iub Transport QoS is used, the IPNB object provides Activity Factors for transport bearers and

mapping tables between various QoS parameters

IPNB = IP NodeBIPQM = IP transmission QoS TQM = Transmission Quality ManagementWRAB = WCEL RAB parameters

WRAB: WCEL RAB parameters • WRAB contains parameters used by

Admission Control for various tasks in configuration of radio bearers

• WCEL refers to WRAB via EbNoSetIdentifier parameter

• there can be 5 WRAB per RNC


IPQM / CMOB

IPQM: IP Quality Management • is used, if IP transport is used on Iu interfaces• it maps traffic classes to DiffServ Code Points (DSCP) which are used to maintain transport QoS• there can be 8 IPQM per RNC, each IU object selects 1 IPQM as template

CMOB: Congestion Management OBject • contains parameters for the WCDMA RAN Access

Regulation feature• this allows to temporarily bar certain Access Classes from accessing the network e.g. in case of disasters or large events• acts only on Access Classes 0 to 9
