• RNC = Radio Network Controller
• WBTS = WCDMA Base Station
• WCEL = WCDMA Cell
• ADJ = Adjacency for WCDMA cell
• ADJS = intra-frequency adjacency
• ADJI = inter-frequency adjacency
• ADJG = inter-system adjacency
• HOP = Handover Path
• HOPS, HOPI, HOPG
• FMC = Frequency Measurement Control
FMCS, FMCI, FMCG
• COCO = Radio Network Connection Configuration

RNC Object• The logical object of the Radio Network Controller • It can have up to 512 WBTS objects (requires RAS51 RNC)• In the RNC object the following interfaces are defined: Iu-PS, Iu-CS and 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 and one COCO object.

• The logical object of the WCDMA Cell is created to define the configuration of the WCDMA Node B site. In one RNC database there can be 1152 WCELs.

Handover PathHOPx
• The Handover Path object stores mainly cell reselection and Intra frequency HHO parameters. One Hop can be related to several Adjacency objects.
• The maximum number of HOPx objects within one 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

Adjacencies ADJx
• Adjacencies for WCDMA cell refers to a handover relationship between two cells. They are defined for neighbouring cells.
• Adjacency Types:
• ADJS — object for intra-frequency Adjacency • ADJI — object for inter-frequency Adjacency• ADJG — object for inter-system Adjacency
There can be 31 intra frequency adjacencies (ADJS), 48 inter-frequency adjacencies (ADJI) and 32 inter-system adjacencies (ADJG)
Handover Path objects must be created before ADJx can be used

Frequency Measurement Control
• The FMC object contains information concerning the frequency measurement functionality of the RNC.
• The maximum number of frequency measurement control objects within one category is 100.
• E.g. for different type of cells (urban, rural, macro/micro/pico)
• One FMC can be related to several WCDMA cells.• FMC Types:
• FMCS — object for intra-frequencyFrequency Measurement Control
• FMCI — object for inter-frequencyFrequency Measurement Control
• FMCG — object for inter-systemFrequency Measurement Control
