1 Activating and testing Dual Band Network Operation (GSM 900/1800, GSM 800/1900, GSM 800/1800, and PGSM 900/EGSM 900)The activation of different Dual Band software products is mutually exclusive and only one of the Dual Band parameters can be activated to the FIFILE.

There are no files involved.

When activating and deactivating Dual Band Network Operation, see the MMLs and parameters in the description of Dual Band Network Operation.

For deactivation instructions, see Deactivating and testing Dual Band Network Opera-tion (GSM 900/1800, GSM 800/1900 and GSM 800/1800).

Before you startMake sure that the following network elements are available:

• one MSC, releases M7A + CN M7_1686, M7B + CN M7_1713 or later • one BSC • two BTSs supporting GSM 900 and GSM 1800, or GSM 800 and GSM 1900, or

GSM 800 and GSM 1800 frequency bands, supporting in releases B10, DF3.0 or later

• one MS (either dual band or tri-band): • a dual band MS supporting GSM 900 and GSM 1800, or GSM 800 (supporting

in MetroSite CXM3.0 and in UltraSite CX3.0) and GSM 1900 frequency bands • a tri-band MS supporting PGSM 900, EGSM 900 (supporting in releases DF3,

without ARFCN 0, and DF4, with ARFCN 0) and GSM 1800 frequency bands

1.1 Activating Dual Band Network Operation (GSM 900/1800)Before you startTo test the activation of Dual Band Network Operation, use the power budget handover (PBGT HO).

Make sure that the following BTSs are available:

BTS1 Accessed cell, allocated from GSM 900 band, adjacent to BTS2. ARFCN allocation according to MS properties (dual band, tri band).

BTS2 Allocated from GSM 1800, adjacent cell to BTS1.

The handovers to be made between GSM 900 and GSM 1800 cells are power budget handovers with negative margins. For more information on power budget handovers, see RF Power Control and Handover Algorithm.

g These values are only for test purposes. The original parameter values should be restored after testing.

Id:0900d8058059c236

Steps

1 Tune the BTS1 and BTS2 to a proper frequency band (BTS1 <-> GSM 900, BTS2 <-> GSM 1800).

2 Set the multiband reporting of BTS1 to 1 (EQM).ZEQM:BTS=1:MBR=1;


4 Set the early sending indication of BTS1 to ON (EQM).ZEQM:BTS=1:ESI=Y;


6 Define BTS2 to be adjacent to BTS1 (EAC).ZEAC:BTS=1::ABTS=2;

7 Define the BTS1 to be adjacent to BTS2 (EAC).ZEAC:BTS=2::ABTS=1;

8 Take into account the adjacencies on the other band of BTS1 (EQF).ZEQF:BTS=1:DBC=Y;

9 Take into account the adjacencies on the other band of BTS2 (EQF).ZEQF:BTS=2:DBC=Y;

Further informationNext, test Dual Band Network Operation (GSM 900/1800).

1.2 Testing Dual Band Network Operation (GSM 900/1800)Steps

Id:0900d8058059c236


3 Set the value of the PBGT HO margin from cell BTS1 to adjacent cell BTS2 to —24 dB to trigger the PBGT HO (EAM).ZEAM:BTS=1::ABTS=2::PMRG=-24;

g The existing value of PBGT HO margin should be restored after the test.

4 Set the value of the PBGT HO margin from cell BTS2 to adjacent cell BTS1 to -24 dB to trigger the PBGT HO (EAM).ZEAM:BTS=2::ABTS=1::PMRG=-24;


Expected outcome

• Dual Band Network Operation is activated in the BSC. • A call is set up to the GSM 900 cell, and successive handovers between GSM 900

and GSM 1800 cells are made. • The test results are verified from the BSC Level Clear Code (PM) Measurements

that indicate the number of successful handovers.

5 Modify BSC Level Clear Code (PM) Measurement (TPM).ZTPM:MEASUR,CC_PM:<measurement day>,<measurement interval><output interval>;

6 Start the measurement (TPS).ZTPS:MEASUR,CC_PM:<start date>,<stop date>;

7 Wait until the measurement is enabled.

8 Interrogate BSC Level Clear Code (PM) Measurement (TPI).ZTPI:MEASUR,CC_PM;

Expected outcomeThe administrative state is UNLOCKED and the operational state is ENABLED.

9 Establish a call to BTS1.The BSC receives radio link measurements which trigger handovers between BTS1 and BTS2.

10 Wait for two minutes.

11 Disconnect the call.

Expected outcomeThe counter 051013 INTERNAL_INTER_HO_SUCCESS is updated in both cells.

13 Stop BSC Level Clear Code (PM) Measurement (TPE).ZTPE:MEASUR,CC_PM;

Expected outcomeThe administrative state is now LOCKED and the operational state is DISABLED.
