BtsFunction attributes Description Example

btsFunctionId This attribute respresents the key of

the BtsFunction MO.

It is used to identify a unique BtsFunction MO instance.

Currently only one BtsFunction MO instance is supported per node.

GRAT MOM Configuration

-BtsFunction

This is the root MO of the GSM MOM fragment.

The BtsFunction MO represents the GSM functionality in the RBS.

The functionality represented by BtsFunction MO can be significantly larger than what is modelled as one TG in the BSC.

(35)

GsmSector attributes

Description Example

GsmSectorId This attribute respresents the key of

the GsmSector MO.

It is used to identify a unique GsmSector MO instance.

This attribute is sent to the BSC for Sector TG to GsmSector correlation purposes.

GsmSector1

GRAT MOM Configuration

-GsmSector

A GsmSector is a geographical area with the RBS functionality used as one GSM cell. GsmSectors can be used in more than one GSM cell depending on BSC configuration. Usage within a GSM cell can be less than the entire GSM cell.

The number of GsmSectors in t he node varies with deployment scenario. More than one GsmSector per node is common.

The GsmSector groups a number of TRXs each represented by a Trx MO. Each TRX supports one GSM c arrier.

(36)

Trx attributes

Description Example arfcnMax{ 0..1023 }

Specifies the number corresponding to the highest frequency for a GSM carrier that the Trx may use.

Each frequency band have separate formulas for downlink (TX) and uplink (RX) to convert between ARFCN and the frequency.

When Synth Hopping is activated, the exact frequency to be used in is ordered by BSC in runtime.

By setting arfcnMin and arfcnMax to the Operator

spectrum available for GSM, frequency re-planning can be made via the BSC wit hout affecting these parameters. …

arfcnMin{ 0..1023 } Specifies the number corresponding to the lowest frequency for a GSM carrier that the Trx may use.

GRAT MOM Configuration –

Trx 1

(3)

This MO represents a GSM TRX and corresponding functionality for a GSM carrier on Air interface. GSM uses narrowband (< 200 kHz bandwidth) channels in the air interface (one downlink and one uplink) handled by one TRX. A TRX handles normally 1 downlink carrier (TX) and 2 uplink carriers (RX) over a wide bandwidth by using frequency hopping. A Trx MO is connected to one

(37)

Trx attributes

Description frequencyBand{ 0, 2, 3, 5, 8 }

Used for configuring the TRX frequency band.

The frequency bands are according to 3GPP TS 37.104, Operating bands and Band Categories, (Band 0 is Ericsson defined).

Possible Values: 0 = GSM 900 MHz (GSM) 2 = GSM 1900 MHz (PCS 1900) 3 = GSM 1800 MHz (DCS 1800) 5 = GSM 850 MHz (GSM 850) 8 = GSM 900 MHz Extended (E-GSM)

Dependencies: Must match arfcnMin and arfcnMax. noOfRxAntennas= 2 { 2 } Specifies the number of RX antennas used by the TRX. noOfTxAntennas= 1 { 1 } Specifies the number of TX antennas used by the TRX.

sectorEquipmentFunctionRef A reference to SectorEquipmentFunction MO (LDN) instance. This MO represents the radio and antenna resources the TRX shall use.

Trx attributes

Description

trxId This attribute respresents the key of the Trx MO, used to identify a unique Trx MO instance.

trxIndex{ 0..126 } This attribute is used both as OML L3 and OML/RSL/TFP/PGSL L2 address (TEI). The value of this attribute is set to trxId if it is a unique number between 0..126, otherwise the lowest unused number in range 0..126 is chosen.

rfBranchRxRef A list of references to MOs RfBranch and CcBranch instances, LDNs. These MOs represent the RF branches the TRX shall use for RX.

If no reference is specified carrier allocation is based on the RF Branch MOM list (default behavior).

rfBranchTx A reference to MO RfBranch instance, LDN.

This MO represents the RF branch (MCPA) the TRX uses for TX. Identifies the RF branch (MCPA) that the PM counters are valid for.

rfBranchTxRef A reference to MO RfBranch instance, LDN.

These MOs represents the RF branches (MCPA) the TRX shall use for TX. This can be used to group TRXs to a MCPA.

If no reference is specified carrier allocation is based on the RF Branch MOM list (default behavior).
