1.1 Purpose
The User Description is mainly written for operators. Its intended use is as a dictionary for more in depth descriptions of the WCDMA Radio Network parameters.
1.2 Scope
This document lists and gives information about the WCDMA RAN Radio Network Parameters. It contains a general description of the parameter, unit, value, range, default value, syntax description, reference to GUI and whether it should be used within tuning
1.3 Structure
To assure that the correct information is delivered to the end-user of this document some of the sheets have

Indicates the node to which the parameter belongs (where it is created and configured).
A new better default value has been found. This value is intended to be the default value in coming releases. Not yet implemented in MOM.
Indicates if the parameter is Read only, Read & write or Restricted. If restricted, once the corresponding MO has been created, the parameter value can only be retrieved (not set) . It could only be modified by recreating the MO.
Indicates whether or not this parameter is mandatory to configure at creation of the corresponding managed object. For mandatory parameters no default value is defined.
Indicates whether or not the parameter is stored persistently in the database of a node. Persistent data will survive a node restart.
Element manager window where the parameter can be viewed or configured.
The name of the BulkCM managed object this parameter belongs to.
Source for initial configuration of each parameter (such as radio network design or system default).
Indicates whether it is recommended to tune the parameter during the initial tuning phase. It is assumed that all initial parameter values have been correctly defined and loaded. Thus, this column disregards consistency and parameter check activities.

Indicates the frequency band of the external GSM cell.
The BCCH frequency is unique for all GSM bands except the two GSM bands DCS1800 and PCS1900, so the band indicator is needed to discriminate between the two. When the ExternalGsmCell has a BCCH frequency indicating some other frequency band, then the band indicator is not needed and may be set to "Not applicable".
Unit: N/AResolution: N/A
This is part of the BSIC.
BCCH frequency code in the GSM cell. Contains the absolute radio frequency channel number of the BCCH channel for the GSM cell. It uniquely identifies the BCCH.
Old name: bcchArfcn
The external GSM cell identity. This is the identity of the GSM cell. It is unique within a location area. The cI along with the LAI (Location area identity) makes up the CGI (cell global identification).

Reference back to the GsmRelation and/or UtranCell MO(s) that refers to this ExternalGsmCell.

Likewise, when the GsmRelation MO is deleted, the system deletes the backward reference to that GsmRelation MO in the same transaction.
When a new attribute directedRetryTarget in UtranCell MO is set to this ExternalGsmCell, the system automatically adds to this sequence a reference back to the UtranCell MO in the same transaction. Likewise, when the UtranCell MO is deleted or its directedRetryTarget attribute is changed, the system deletes the backward reference to that UtranCell MO in the same transaction.

Cell Relation
Definitions:
UTRAN CELL RELATION:The UtranRelation MO type models the manageable characteristics of the relation to a neighbouring Cell of type Utran, e.g. MO Utran Cell (intra RNC Handover) or MO ExternalUtranCell (inter RNC handover).
It is a cell relation where the source UtranCell and the target UtranCell reside at the same or different frequencies and reside in the same RNC or a different RNC.
Limits on cell relation definition:- Number of UtranRelation instances of type intra frequency may not exceed 31.- Number of UtranRelation instances of type inter frequency may not exceed 32.- The allowed total number of cell relations in a UtranCell (UtranRelations (63)+GsmRelations (64) <= 127) also depends on the configuration of the system information distribution. An algorithm is used to calculate number of cell relations supported on the BCCH when the Sid MO is configured. A new configuration on the Sid MO will be rejected if there currently is a UtranCell within the RNC that have more cell relations configured than the new configuration can support. A check is made against this limit (calculated by the algorithm) when a cell relation is added to a cell.
- The allowed total number of cell relations that can be configured in the RNC node is 93000.
- The allowed total number of Utran cells that can be configured in the RNC node is 1500.
EXTERNAL GSM NETWORK:The ExternalGsmNetwork MO type models the manageable characteristics of an external Gsm Network. It is an image of a Gsm Network.
EXTERNAL GSM CELL:ExternalGsmCell MO type models an external GSM cell. It is an image of a GSM cell. For Inter Radio Access Technology handover purpose the RNC needs to store GSM cell information.

GSM RELATION:GsmRelation MO type models the manageable characteristics of the relation to an external GSM neighbour cell. The information is valid for Inter Radio Access Technology Handover.Its is a cell relation between a source UtranCell and a target cell that belongs to a GSM System.
Limits on cell relation definition:The allowed total number of cell relations in a UtranCell (UtranRelations+GsmRelations <= 95) also depends on the configuration of the system information distribution. An algorithm is used to calculate number of cell relations supported on the BCCH when the Sid MO is configured. A new configuration on the Sid MO will be rejected if there currently is a UtranCell within the RNC that have more cell relations configured than the new configuration can support. A check is made against this limit (calculated by the algorithm) when a cell relation is added to a cell.
COVERAGE RELATION:Models the manageable characteristics of the relation of an UTRAN cell to a another UTRAN cell. The source UTRAN cell and the target neighbouring UTRAN cell may reside at the same or different frequencies but must always reside in the same RNC. The maximum number of coverage relations for a UtranCell is one. .

UTRAN CELL RELATION:The UtranRelation MO type models the manageable characteristics of the relation to a neighbouring Cell of type Utran, e.g. MO Utran Cell (intra RNC Handover) or MO ExternalUtranCell (inter RNC handover).
It is a cell relation where the source UtranCell and the target UtranCell reside at the same or different frequencies and reside in the same RNC or a different RNC.
Limits on cell relation definition:- Number of UtranRelation instances of type intra frequency may not exceed 31.- Number of UtranRelation instances of type inter frequency may not exceed 32.- The allowed total number of cell relations in a UtranCell (UtranRelations (63)+GsmRelations (64) <= 127) also depends on the configuration of the system information distribution. An algorithm is used to calculate number of cell relations supported on the BCCH when the Sid MO is configured. A new configuration on the Sid MO will be rejected if there currently is a UtranCell within the RNC that have more cell relations configured than the new configuration can support. A check is made against this limit (calculated by the algorithm) when a cell relation is added to a cell.
- The allowed total number of cell relations that can be configured in the RNC node is 93000.
- The allowed total number of Utran cells that can be configured in the RNC node is 1500.
EXTERNAL GSM NETWORK:The ExternalGsmNetwork MO type models the manageable characteristics of an external Gsm Network. It is an image of a Gsm Network.
EXTERNAL GSM CELL:ExternalGsmCell MO type models an external GSM cell. It is an image of a GSM cell. For Inter Radio Access Technology handover purpose the RNC needs to store GSM cell information.

Location Area (LA) consists of a number of cells and is used by the UTRAN to page UEs in all cells in the LA on request from the Circuit SwitchCore Network.
Service Area (SA) consists of a number of cells and is used by the UTRAN to indicate the location of a UE to the Core Network.
Routing Area (RA) consists of a number of cells and is used by the UTRAN to page UEs on request from the Packet Switched Core Network.
The areas LA, RA, SA also reside in the Core Network. They can span over several RNCs in UTRAN.
The maximum number of LAs, RAs or SAs in RNC is 1500. That is when LA, RA, or SA contains only one cell in a RNC configured with 1500 cells.
