Overview
This scenario defines how to perform a massive logical update to:
•
•
•
•
Modify the frequency plan
Modify the frequency hopping mode
Modify different logical parameters on cells
Create / delete / modify adjacencies and external cells.
These modifications optimize the performance and capacity of the network.
Note that BSC parameters cannot be modified via the MLU.

Overview
Presentation
....................................................................................................................................................................................................................................
A frequency plan can cover a complete network, which can be under the control of
several OMC-Rs. An OMC-R is impacted if it contains cells directly modified by the
frequency plan, or cells that are in the neighborhood of modified cells. Analyzing the
impact on neighboring cells is essential in order to avoid losing handover relationships.
This method applies to both the 9120 BSC and the 9130 BSC Evolution.
Tip: If you do not have a thorough knowledge of the impacted cells, assume that all
the OMC-Rs of the network are impacted.
Non-Alcatel-Lucent OMC-Rs can also be impacted. Although updating such OMC-Rs
does not concern Alcatel-Lucent, it is mentioned in the scenario as a reminder.
The OMC-Rs export their frequency information in the 9153 OMC Configuration Import
/ Export (ACIE) format.
For more information about this format, refer to:
•
•
9153 OMC-R Configuration Import/Export Interface
9153 OMC-R Configuration Import/Export Interface: Supplementary Information.
Several comma-separated value (csv) files are generated, which cover the complete
configuration of the OMC-R.

Only five of these files and attributes are relevant for frequency modification. The
following table gives the names of the files and the relevant attributes.

Preparation
Prerequisites
The following prerequisites apply:
•
•
Before you activate an MLU, you must perform a lock on all BTS-O&M that are in a
faulty state
If an External Tool is used, it must be able to interpret the format of the exported
OMC-R file. The tool's output file must also conform to the same format, so that it
can be imported back into the OMC-R.
For more information, refer to:
– 9153 OMC-R Configuration Import/Export Interface
– 9153 OMC-R-Configuration Import/Export Interface: Supplementary
Information.
The 9159 NPO can interpret and output to this format.
Note: Estimated durations of tasks described in this document are not applicable for
overloaded OMC-Rs.
Site Specific Information
You must have the following information to complete the scenario:
•
•
Site database (location, topography, antenna direction, etc.)
OMC-R user name and password for network reconfiguration
•
•
•
•
Neighborhood relationships (adjacencies)
Border coordination
Coverage plots
Policy on preferred frequency usage.
External Tasks

Import / Synchronize PRC
Overview
Do not perform multiple imports of the same cell into the same PRC. Cells must be
imported only once into the PRC.
In order to avoid any discrepancies that could appear between the imported (modified)
configuration and the SC, these files will be imported at a pre-determined time before
applying the MLU session.
Note: To import a fresh OMC-R configuration in NPO, refer to Import Parameter
Values from the NPO Administration Guide.
Procedure
Import or synchronize the PRC:
...................................................................................................................................................................................................

Run the External Tool program to create the import files.
If the 9159 NPO is used, refer to Tuning Session Manager from the NPO User Guide and
perform the following steps:
1. Create Tuning Session
2. Check Tuning Session
3. Apply Tuning Session
4. Check if the file generated by tuning session was sent to OMC-R. Select:

Overview
Attention: No changes can be made once the Apply MLU Session is started from
the PRC.
If there is a doubt about the PRC and you have to close the MLU session on a part of
the BSCs before activating the MLU package, the cells became misaligned on the
concerned BSCs. Perform a rollback and a logical audit on the required BSCs to get
the initial configuration, as described in “Reverse Procedure without Accept”
(p. 2-35).
Also, to recover the initial values in the MFS, it is necessary to activate the Backup
PRC, but only for the required BSCs; refer to “O1: Activate Backup PRC” (p. 2-39)).
Note: When only MFS parameters are modified by applying MLU, a sand-clock
appears only on the GPRS side of the impacted cells (no sand-clock appears on the
GSM side), and the cell aligning status is Aligning Down. In this case, to finish the
modifications, perform only Activate MFS for MLU Package, as described in
“Activate MLU” (p. 2-29).

Apply the MLU Session.
From the Working PRC, Apply MLU Session. The MLU can be applied with or without
cells cleanup.
It is recommended to apply the MLU session with cells cleanup because the cells that
were not modified are removed from the PRC and as a result the activation takes less time
and it reduces the risk of overwriting other modifications performed in the network since
the PRC creation time.
Note: This PRC can be applied with cells cleanup only once (when applying it for the
first time).
A result window appears. When the operation is complete, the BSC Current Session
Status flag in the RNUSM Matrix Browser window changes from No Session to MLU
Session and the status of all impacted cells becomes aligning down. Wait until the
Progression Status changes from Idle to In Progress for all BSCs involved in the MLU.
If only MFS parameters are modified, the BSC Current Session Status flag in the

for supervision purposes it is recommended that you download only four 9120 BSCs
at a time. There is no restriction on the number of 9130 BSC Evolution to be
downloaded at the same time.
If an error message such as
JobUnsuccessful has been received from the BSS: BSC_disk_

Overview
Attention: There is no restriction on the number of BSCs that you can select for
activation, but for supervision purposes, it is recommended that you activate only four
9120 BSCs at a time. There is no restriction on the number of 9130 BSC Evolution to
be activated at the same time.
Repeat all the tasks below for each group of BSCs.
Procedure
Activate the MLU:
...................................................................................................................................................................................................

Activate the MFS for the MLU Package.
From the SC, Activate MFS for MLU Package.
If only MFS parameters were modified and if the MFS does not appear in the displayed
list, it means that the previous task (Apply MLU Session) is not finished yet. Do not
continue the current task until the MFS appears in the list.
Wait until, in the RNUSM Matrix Browser window, in OMC MFSs, the Reservation Status
changes from Busy to Idle.
Note: Perform the next task immediately after the MFS is successfully activated, in
order to limit the time during which the BSC and the MFS are de-synchronized.
