2.1 BSS Software Replacement (C1 and C2 only)At the OMC-R site:

Using the corresponding BSS Software Replacement method, perform softwarereplacement on the impacted BSS with the generic SDP package required inthe Prerequisites (Section 1.2.1).

During the BSS software replacement once the activation is finished in theSoftware information window check in the "new Software directory" thepresence of the following additionally BTS master file:

** : A5/3 ciphering algorithm is used starting with B11.BSS Software Replacement isnot necessary to change the ciphering algorithm in B11 release.

: The ciphering algorithm is changed at cell level in B11 release. For details seesection Change Cell Cipher Capabilities ( for C3 only) (Section 2.4)

Where:

YY.ZZZ represent the new BSS version

2 Scenario

2.2 Change BTS Cipher Capabilities for one BTS (C1 and C2)Choose the appropriate case if needed.

2.2.1 At the OMC-R Site

To change the BTS cipher capabilities perform the following steps for each BTS:

1. From ’BSSUSM Main View’ window select the impacted BTS

2. Right-click on the selected BTS and from the pop-up menu select Navigateto Abis View

3. ’Abis topology view’ window opens, with the selected BTS marked

2.2.2 C1: BSS software version is B7.2

1. Right-click on the marked BTS and from the pop-up menu select Modify BTS.

2. In the "Modify BTS Hardware Capabilities " window select [ Advanced ]tab and change the ciphering parameter from the current value to theneeded one.

3. Apply the modification using the [ Apply ] button.

4. In the "BSSUSM : Follow up" window the messageModifyBtsHardwareCapabilities appears.

RESTRICTION3BK20FBR149768

During the Modify BTS Hardware Capabilities a false failure could besporadically reported by the BSC due to expiring of BSC’s confirmationtimer for BTS acknowledge, with the following message: "...A messagewith JobUnssuccesful has been received from the BSS: FM Errornfo:34-fc-lower-cnf-tme-exp.A time out message received for a dependantobject for the action sbl_init.bssim-4559".

If the BTS O&M will look failed in BSSUSM window, the status can be correctedby launching a BTS HW audit for affected BTS.

2.2.3 C2: BSS software version is B8, B9 or B10

1. Right-click on the marked BTS and from the pop-up menu select ModifyBTS HW Capabilities. In the "Modify BTS HW Capabilities" window select[ Ciphering ] tab and change the ciphering parameter from the currentvalue to the needed one.

2. Apply the modification using the [ Apply ] button.

3. In the "BSSUSM : Follow up" window, the messageModifyBtsHardwareCapabilities appears.

3DF 00300 0105 UAZZA Ed.09 13 / 20

2 Scenario

2.3 Change BTS Cipher Capabilities for more BTSs (only for C2)

2.3.1 At the OMC-R Site

To change the BTS cipher capabilities for more BTSs perform the followingsteps:

1. From "BSSUSM Main View", in ’Functional Alarm Synthesis’ frame clickon [ Abis ] icon

"Abis topology view" window opens

2. For 9120 BSC select the impacted TSU

3. For 9130 BSC Evolution select multiple BTSs

4. Right-click on the marked TSU/BTSs and from the pop-up menu selectModify BTS HW Capabilities

5. In the "Modify BTS HW Capabilities" window click on the tab related to theBTS which requires a ciphering change

6. In the ’Ciphering’ field change the ciphering parameter from the currentvalue to the needed one

7. When the ciphering parameter has been changed for all impacted BTSs,click on [ Apply ] to take the modifications into account

8. In the "BSSUSM : Follow up" window, the messageModifyBtsHardwareCapabilities appears.

RESTRICTION3BK20FBR172288

After the cipher for the BTS was successfully changed (visible in Follow-up), ifthe [ RESET ] button becomes red this can be corrected by pressing [ RESET ]button.

Wait for the cipher modification to end before starting a new operation onany other BTS.

2.3.2 At the NSS Site

After all BTS cipher capabilities were changed at the OMC-R site, the cipheringmode must be changed in MSC according with the new cipher value.

14 / 20 3DF 00300 0105 UAZZA Ed.09

2 Scenario

2.4 Change Cell Cipher Capabilities ( for C3 only)The A5/3 ciphering algorithm introduces the parameter CELL_CIPH_SET, atcell level, which defines which chipering algorithms are enabled. It is possibleto enable A5/0 (no chipering), A5/0 + A5/1 or A5/0 + A5/1 + A5/3. The BTS(TDM or IP) support A5/3 only for G4 /G5 TREs.

The A5/3 ciphering algorithm only concerns the Circuit Switched domain.

The A5/3 is an optional feature sold according to a number of TRX.

For a call, A5/3 is used if:

MS supports A5/3, as indicated in Class mark 2

TRX supports A5/3

The operator has enabled A5/3 support for the cell

NSS allows the use of A5/3

DTM is not enabled in the cell or DTM is enabled and the Ciphering Mode

Setting Capability of the MS bit is enabled.

4. Click on[ Apply ] and then click on [ Close ].

2.4.2 Change the Cipher Capabilities for n Cells

This task allows you choose a group of cells (’n’ ), modify certainsystem-displayed parameters, and apply the modifications to the entire group.

This task can only be performed in a PRC.

To change the cipher capability for n cells perform the following steps:

2.4.2.1 Copy the OMC Cells to PRCTo copy the required OMC Cells to PRC:
