3. SUMMARY
Within RU30/I-HSPA Rel.4 a new baseband concept is introduced
for Flexi Rel. 2 BTSs: RAN 2123 Flexi BTS Gigabit Baseband. The new
concept required a conversion from RU20s/I-HSPA Rel.3 baseband to
RU30s/ I-HSPA Rel.4 baseband. The conversion is supported by the
tool RU30BBconv tool which is part of WBTS 7.0 SW delivery. The
conversion using the tool has to be executed before upgrading the
BTS to WBTS 7.0. Running the conversion can be seen as part of BTSs
upgrade. BB conversion is mandatory to perform for all sites before
WN7.0 SW upgrade. The procedure can be applied for both - upgrading
BTSs from RU20 to RU30 EP1 or from RU20 to RU30 EP2. In case the
conversion has not been applied, the upgraded BTS would not be
enabled for HSxPA. Based on the RU20s configuration, conversion
rules define how many baseband resources the customer will get.
This has commercial impact. Before running the conversion, these
rules have to be agreed between the customer and NSN. According to
these commercial agreements, the conversion tools parameters as
described in that document have to be set accordingly. In general
the conversion is executed by NSN. If the conversion is intended to
be executed by the customer, NSNs customer team has to accept that.
This document describes how to make the BB conversion by using RU30
Conv-tool before upgrading BTS to WN7.0 (RU30) level. Based on
WBTSs baseband configuration on WN6.0 SW level the BTSs baseband
configuration on WN7.0 level is calculated.

Information about different processing sets For converting RU20s
BB configuration into RU30s BB configuration NSNs conversion tool
RU30Conv Tool has to be used. This conversion is part of the BTSs
upgrade from RU20 to RU30 (WN 6.0 -> WN7.0) and results into a
dedicated number of HSDPA BTS Processing Set 1, HSDPA BTS
Processing Set 2, HSDPA BTS Processing Set 3, HSUPA BTS Processing
Set, Rel. 99 CEs and configured HSDPA throughput. For HSDPA: HSDPA
BTS Processing Set 1: 32Users/7.2Mbps HSDPA BTS Processing Set 2:
72Users/21Mbps HSDPA BTS Processing Set 3: 72Users/84Mbps For
HSUPA: HSUPA BTS Processing Set: 24Users/5.8Mbps For Rel. 99
traffic Rel.99 CEs are introduced.
As the RU30s baseband concept has been introduced for Flexi
Rel.2 only, the conversion becomes effective for Flexi Rel. 2 only.
As within WN6.0 an extension module can be added without
re-commissioning, in those cases the BTS SCF will not contain Rel.2
System Module information. Consequently the conversion will make
some assumptions, which allows to generate processing sets for
these mixed configurations (SM1 & SM2), which have been
extended in WN6.0 without re-commissioning. Details have been
described in chapter 5.9.
3.1 Location of the BB conversion tool

APPROVED version 22.0 Page 8
Input of the tool is a XML file (RAML 2.0) containing
configuration data from the BTS SCF (Site Commissioning File) and
RNC RNW (Radio Network).
In the directory where script is executed, a file called
raml20.dtd must be available.
The key data used for the conversion are:
From BTS:
Type of scheduler used in BTS
Kind of HW used (Rel.1 and / or Rel.2)
Number of schedulers
MIMO enabled / disabled
From RNC
HSDPA enabled / disabled
HSUPA enabled / disabled
HSPA72UsersEnabled
HSUPAXUsersEnabled
DC-HSDPA enabled/disabled
64 QAM enabled/disabled
Based on conversion rules implemented in the tool, the tool
generates as output:
XML file (RAML 2.0) containing RU30 BB configuration (dedicated
number of HSDPA BTS Processing Set 1, HSDPA BTS Processing Set 2,
HSDPA BTS Processing Set 3, HSUPA BTS Processing Set, Rel. 99 CE
consumption and Throughput via the parameter hsdpaSchedList)
and
Text file containing # HSDPA BTS Processing Set 1, # HSDPA BTS
Processing Set 2, # HSDPA BTS Processing Set 3, # HSUPA BTS
Processing Set and Rel. 99 CE consumption, which allows the
operator to see how many licenses need to be loaded to the NetAct
pools before upgrading the BTSs to RU30.
XML file, which contains a list of BTSs, which have been
converted to be used for the cleanup script

1) The tool generates Rel. 99 CE license consumption. After the
upgrade to RU30 the BTS calculates the real number of Rel. 99 CEs
via installed CE licences Rel.99 CE license consumption.
2) The tool has input parameters, which allow flexible handling
of conversion rules agreed between customers and customer teams.
Consequently additional Rel.99 CEs can be assigned and HSxPA
processing set configuration can be extended or reduced. Via those
parameter settings it can be selected, if commissioned throughput
should be affected or not affected.
Tools delivery consists on the following files:
RU30BBconv.exe (script to run the conversion)
RU30BBconv.exe.config (contains configuration parameters to be
opened with a simple editor)
RU30BBconv_Custom.exe.config (used to handle different
configuration parameter setting - to be opened with a simple
editor)
raml20.dtd (file has to be available in the same directory as
the input XML)
RU30BBconv_ReadMe.txt (Read me file)
5. SOLUTION / INSTRUCTIONS
5.1 Description of conversion procedure
Pre-condition: NetAct has to be upgraded to RU30 level (OSS 5.4
CD 1 or higher)
The steps below provide functional descriptions. Screen shots
showing detailed steps have been added to Appendix 8.1.
Freeze of BTSs to be migrated. No modification on BB
configuration allowed anymore.
1) For the BTSs to be converted (possible approach, e.g. all
BTSs belonging to a RNC): Use the CM Operations manager in NetAct
Configurator to upload BTS site configuration and hosting RNCs RNW
data into the NetAct Configurator Database. After that upload, all
BTS Site Configuration data and RNC RNW data is available in the
NetAct Database.
2) Export that RU20s configuration (RNC RNW and BTS SCF) from
the NetAct DataBase into an RAML 2.0 file using internal parameter
values. Do not use any options from Export Options window (under
Options button).
Objects to be exported:
-

APPROVED version 22.0 Page 10
RNC : WBTS, WCEL
BTS : BTSSC, LCEL, LCELG, ANTL
3) Run RU30Conv Tool through exported RAML 2.0 file. According
to conversion rules, an output RAML 2.0 file and a readable .txt
file will be generated containing dedicated Baseband parameters (#
processing sets and # Rel.99CEs consumption). This .txt file shows
# licenses needed and have to be ordered and loaded to the NetAct
pool. For Rel.99 CEs, the tool calculates the Rel.99 CE
consumption, which are Rel.99 CEs reduced from existing CEs @ RU20.
The difference from existing RU20 CEs is needed to be ordered. See
chapter 5.6 and Q&As describing more details 6.1.
4) Import generated output RAML 2.0 file back to the NetAct
Configurator. 5) Trigger NetAct configurator to create SCF (Site
Commissioning Files) and
download these SCFs to all related BTS (part of the conversion).
BTSs are still on RU20. The BTSs accept these parameters, but dont
use them.
6) Upgrade the related BTSs to RU30. New BB parameters will
become effective.
i. Feature RAN2131: Automatic Licence Distribution to Flexi BTS
automatically loads all licenses needed.
ii. Use License Manager application on NetACt, and check the new
HSDPA/HSUPA and R99 CE capacity Licence are ACTIVE and the old
Licence Based BTS channel capacity INACTIVE.
Remark: In case RAN2131 is disabled, licenses have to be
assigned manually.
7) Optional Step: Run NetAct Cleanup script for deleting
licenses no longer needed
a. Script deletes licenses from BTS and returns capacity to the
NetAct pool.
b. Input for that script is XML file from the RU30ConvTool
Remark: Cleanup script is packaged on OSS53CD3_LIC_5.30.42 or
later
Note 1: The script has defined input parameters (chapter 5.2),
which allow to modify the standard conversion rules. In alignment
between customer and customer team those parameters have to be set
accordingly. In case these parameters have not been set, conversion
is performed according to standard conversion rules. Note 2: The
script generates a readable .txt file, which shows # licenses
needed. Those licenses have to be ordered and loaded to the NetAct
pool, before the BTS is upgraded to RU30.

APPROVED version 22.0 Page 11
Note 3: As the cleanup script removes the NWS licenses, it
should be applied only when it is ensured that no rollback is
needed. Otherwise a rollback would require the re- installation of
licenses.
Note 4: Before starting the export of the configuration data,
the baseband configuration of the BTSs to be exported has to be
frozen. No re-configuration is allowed anymore.
5.2 Parameters of the RU30 Conv-tool
These parameters impact the BB configuration calculated by the
tool and consequently the # of licenses requested by the BTS.
Before the conversion is executed, those parameters have to be
agreed between the customer and NSN. Especially the parameter
HSUPA_CE_Consumption_Multiplicator needs dedicated attention, as it
significantly impacts the number of Rel.99 CEs available after the
conversion. It may risk that after the conversion the BTS is
running out of Rel.99 CEs. Those parameters have to be agreed
between the customer and NSN.
additional_numberOfHSDPASet1: to add additional number of HSDPA
Processing Set 1 for the BTSs to be converted, in case no Like2Like
conversion is required (operator gets more). This parameter does
not impact the throughput calculation and not the calculated number
of used CE licenses. E.g., if that parameter is set to 1, then for
all BTSs in the conversion, the configuration parameter for # of
processing set 1 are increased by 1, which results that the BTSs
will request one additional license. In case of usage of predefined
values, e.g. predef_HSDPA_PS_x or pre_def_thrp_per_SM_x,
predef_HSU_PS, predef_CE_consumption this parameter is ignored.
Set1_throughput: This parameter is similar to
additional_numberOfHSDPASet1, but also impacts the throughput
calculation. Via that parameter it is possible to add or to reduce
# of HSDPA processing set 1 , which impacts both: # of configured
processing set 1 (and consequently related licenses) and
throughput. In case of usage of predefined values, e.g.
predef_HSDPA_PS_x or pre_def_thrp_per_SM_x, predef_HSU_PS ,
predef_CE_consumption, this parameter is ignored.
additional_numberOfHSDPASet2: to add additional number of HSDPA
Processing Set 2 for the BTSs to be converted, in case no Like2Like
conversion is required (operator gets more). This parameter does
not impact the throughput calculation and not the calculated number
of used CE licenses. E.g., if that parameter is set to 1, then for

predef_CE_consumption, this parameter is ignored.
Set2_throughput: This parameter is similar to
additional_numberOfHSDPASet2, but also impacts the throughput
calculation. Via that parameter it is possible to add or to reduce
# of HSDPA processing set 2, which impacts both: # of configured
processing set 2 (and consequently related licenses) and
throughput. In case of usage of predefined values, e.g.
predef_HSDPA_PS_x or pre_def_thrp_per_SM_x, predef_HSU_PS ,
predef_CE_consumption, this parameter is ignored.
additional_numberOfHSDPASet3: to add additional number of HSDPA
Processing Set 3 for the BTSs to be converted, in case no Like2Like
conversion is required (operator gets more). This parameter does
not impact the throughput calculation and not the calculated number
of used CE licenses. E.g., if that parameter is set to 1, then for
all BTSs in the conversion, the configuration parameter for # of
processing set 3 are increased by 1, which results that the BTSs
will request one additional license. In case of usage of predefined
values, e.g. predef_HSDPA_PS_x or pre_def_thrp_per_SM_x,
predef_HSU_PS , predef_CE_consumption, this parameter is
ignored.
Set3_throughput: This parameter is similar to
additional_numberOfHSDPASet3, but also impacts the throughput
calculation. Via that parameter it is possible to add or to reduce
# of HSDPA processing set 3, which impacts both: # of configured
processing set 3 (and consequently related licenses) and
throughput. In case of usage of predefined values, e.g.
predef_HSDPA_PS_x or pre_def_thrp_per_SM_x, predef_HSU_PS,
predef_CE_consumption, this parameter is ignored.
additional_numberOfHSUPASet: to add additional number of HSUPA
Processing Set , in case no Like2Like conversion is required
(operator gets more). This parameter does not impact the calculated
number of used CE licenses. In case of usage of predefined values,
e.g. predef_HSDPA_PS_x or pre_def_thrp_per_SM_x, predef_HSU_PS,
predef_CE_consumption, this parameter is ignored.
additionalR99CEs: to add additional number of Rel.99 CEs, in
case no Like2Like conversion is required (operator gets more). As
the configuration parameter for Rel.99 CEs has been increased, the
BTS will request that additional amount on Rel.99 CE licenses. In
case of usage of predefined values for Rel.99, this parameter is
ignored.
HSUPA_CE_Consumption_Multiplicator: CE consumption for HSUPA.
This parameter is needed to be set explicitly and needs dedicated
attention.

to assign a fix value for Rel.99 CEs, which are available after the
upgrade to RU30. This parameter allows to define a fix value of
Rel.99 CEs to be reduced from CEs available @ RU20 (see chapter

Rel99CEconsumpt_CCCH (off/on) On: In case of CCCH processing
resources included in Flexi Rel2 system module are not sufficient
for current BTS cell configuration, additional CCCH processing
subunit(s) are allocated. These CCCH processing subunits consume
Rel.99 CE licenses. In RU20, one subunit capacity was 36CEs and in
RU30 its capacity has been increased to 48CEs. For that reason per
each additional CCCH subunit, the conversion tool subtracts 12 CEs
from the CE consumption, which means that during the upgrade,
additional 12 CEs licenses are given for free. Off:CCCH processing
resources are not considered and no Rel.99 CEs are substracted from

steps and sched 2 would get 9 steps, then decrease 3 steps from
sched 1 and add these 3 steps to sched 2, which will result to:
sched 1: 12 steps and sched 2: 12 steps; In case the value
max_throughput_steps_per_scheduler is selected too low, which would
not allow to get distributed all the throughput steps, the
parameter is ignored and the throughput is assigned without
considering that parameter. In case of one active scheduler in use,
this parameter is ignored as well.
force_for_extension = off /FSMC/FSMD/FSME
Within WN6.0 it was possible to add an extension module without
re-commissioning (hot insert). In those cases where
re-commissioning has not been performed after extension modules
insertion, the BTS SCF does not contain extension module
information. For those sides the conversion tools output can be
wrong (wrong number of processing sets generated; wrong
distribution on throughput). This option solves the problem. Sides
where hot insert has been applied should be converted by applying
the parameter force_for_extension. The module type, which has been
inserted, is indicated by FSMC or FSMD or FSME. Note: The option
force_for_extension only has to be applied for BTSs, which really
have been extended via hot insert. For restricting the BTSs to be
converted, the li, resp. li_file option can be applied.
transfer_to_PS3 (off/on/on_thrp).
This parameter instructs the tool always to report PS3 results.
Just based on the number of processing sets calculated,
independently on type of processing sets (PS1, PS2, PS3),
conversion tool always reports processing set 3.
o In case of transfer_to_PS3 = on, just processing sets are
calculated without impacting the throughput.
o In case of transfer_to_PS3 =on_thrp, processing sets are
calculated by increasing the throughput.

Remark 1: a) Rules for setting the parameters
pre_def_PS_y_per_SM_x /
pre_def_PS_y_per_SM_x_DC. Setting one parameter, but no values
for the others results that
pre_def_PS_y_per_SM_x = pre_def_PS_y_per_SM_x_DC
the other parameters get the value 0 Example 1 :
Setting the parameter pre_def_PS_2_per_SM_D_DC=3, but no values
for the other pre_def_xx_per_SM parameters results to:

Setting the parameter pre_def_PS_2_per_SM_D=3, but no values for
the other pre_def parameters, results to: pre_def_PS_2_per_SM_C=0
pre_def_PS_2_per_SM_D=3 pre_def_PS_2_per_SM_E=0

b) Setting explicit values for the parameters
pre_def_PS_y_per_SM_x / and pre_def_PS_y_per_SM_x_DC without
assigning values for the others, results in assigning the value 0
for the other parameters.
Example 3: Setting the parameter: pre_def_PS_2_per_SM_D=3 AND
pre_def_PS_2_per_SM_D_DC=6, results to: pre_def_PS_2_per_SM_C=0

pre_def_PS_2_per_SM_E_DC=0 c) pre_def_thrp_per_SM_x only can be
used in combination with
pre_def_PS xx Via pre_def_PS xx you will assign processing sets
resulting in dedicated licenses. The throughput can be modified via
pre_def_thrp_per_SM_x. Example 4: Operator sets:
pre_def_PS_2_per_SM_E_DC=2 througput assigned for FSME is always
42Mbps But setting pre_def_thrp_per_SM_E= 12 (== 84Mbps), would
result that 2 PS2s per FSME have been assigned with throughput
configured: 84Mbps for FSME Example 5: FSME (HSDPA without DC) +
FSME (HSDPA with DC) Pre-condition:
Predef_PS_2_per_SM_E = 2 (=> 2x21Mbps = 6 throughput

Remark 2: The two parameters shareOfHSUPALicences and
shareOfHsdpaUser always are part of the output XML generated.
shareOfHsdpaUser : Setting the parameter shareOfHsdpaUser is set
depending on the number of schedulers of the LCGs it had in RU20.
Example: If there are two LCGs and LCG1 has 2 schedulers and LCG2
has 1 scheduler then in RU30 LCG1 should have 66% of the users and
LCG2 34% of the users. shareOfHSUPALicences: Depending on the
number of processing sets calculated for the LCGs, the share of
HSUPA licenses is set accordingly. Example: If there are two LCGs
and the conversion tool calculates for LCG1 3 HSUPA PSs and for
LCG2 7 HSUPA PSs, then shareOfHsupaLicenses for LCG1 will be 100% x
3/(3+7) = 30% and shareOfHsupaLicenses for LCG2 will be 100% x
7/(3+7) = 70%. Without that parameter setting, the conversion tool
would give 10 processing sets in total and without defining the
parameter shareOfHSUPALicences, the processing sets would be
distributed evenly (5 for each LCG). In case the need to switch off
(not to generate these parameters), the command interface can be
used:

parameters pre_def_HSU_per_SM_x, pre_def_HSU_per_SM_x_DC and
predef_HSU_PS, the parameter shareOfHSUPALicences is calculated
according to the following rules:
- if there exists Rel1 FSM then the LCG which is located in Rel2
ESM gets 100% of HSUPA licenses
- if there is no Rel1 FSM in configuration then each LCG gets
share of licenses proportional to number of HSPA enabled cells
(WCEL objects corresponding to LCEL objects of that LCG which have
HSDPAEnabled or DCellHSDPAEnabled set to true).
- In case of just one LCG, then this parameter is not generated.
In case the need to switch off, the command interface still can be
used:

5.3 Usage of flexible configuration files
This functionality allows to apply user specific configuration
files. In addition to the configuration file RU30BBconv.exe.config,
applying the option -- config - an additional configuration file
can be entered. That overwrites the settings of
RU30BBconv.exe.config. Applying that option, offers the possibility
to have common values in RU30BBconv.exe.config and in addition
different customer specific config files. The format of that
customer specific configuration file is as defined in the

conversion.
5.5 BTS specific settings on processing sets and Rel.99 CE

5.6 Rel.99 CE license consumption calculated by the tool
As in WBTS 7.0, CE capacity is replaced by HSxPA processing
sets, licensed CE capacity from WBTS 6.0 will be reduced
accordingly and remaining Rel.99 CE licenses will be assigned to
the WBTS7.0. The CE license reduction can be impacted by parameters

additionalR99CEs_per_SM_x which have to be agreed between NSN
and the customer before the conversion is executed. The reduction
of Rel.99 CEs licenses is called Rel99 CE consumption. # Rel.99 CE
licenses @ WBTS7.0 = max {# CE licenses @ WBTS 6.0 - Rel99 CE
consumption, 0} ; # Rel.99 CE licenses @ WBTS7.0 is calculated by
the BTSs startup. Rel.99 CE consumption is calculated in the
following way: Rel99 CE consumption of HSPA for one BTS:
HSDPA_CE_Consumption + HSUPA_CE_Consumption - additionalR99CEs ;
HSDPA_CE_Consumption = ((number of 16 per BTS schedulers x 36 Rel99
CEs) + (number of 16 per cell schedulers x 36 Rel99 CEs) + (number
of full BB schedulers x 72 Rel99 CEs) + (number of efficient BB
schedulers x 72 Rel99 CEs))* HSDPA_CE_Consumption_Multiplicator;
HSUPA_CE_Consumption = # HSUPA processing sets *
HSUPA_CE_Consumption_Multiplicator;
Note 1: Consequently, in case Rel.99 CE consumption is higher
than # CE licenses @ WBTS 6.0 (Feature Code 308), WBTS7.0 will not
get Rel.99 CE licenses. Note 2: In case of CCCH processing
resources included in Flexi Rel2 system module are not sufficient
for current BTS cell configuration, additional CCCH processing
subunit(s) are allocated. These CCCH processing subunits consume
Rel.99 CE licenses. In RU20, one subunit capacity was 36CEs and in
RU30 its capacity has been increased to 48CEs. For that reason per
each additional CCCH subunit, the conversion tool subtracts 12 CEs
from the CE consumption, which means that during the upgrade,
additional 12 CEs licenses are given for free (via configuration
parameters, this behavior can be switched off). Note 3: The
conversion tool offers the possibility to assign a fix value of
Rel.99 CE consumption (see parameter: predef_CE_consumption). To
make it absolutely clear: Setting this value does not mean to
assign a fix value for Rel.99 CEs, which are available after the
upgrade to RU30. This parameter allows to define a fix value of
Rel.99 CEs to be reduced from CEs available @ RU20. The number of
CEs, which have been assigned to an NE can be retrieved by using
the NetAct license manager.

for the shared scheduler on frequency 3 we get 1 PS 2.

In total 21 steps = 151 Mbps have to be distributed. The
assignment of cells to the scheduler is according to the TCell
Values assigned in RU20. TCell values are from 0..9 and according

Calculation of throughput - based on weight distribution:
Weight @ Sched 1 (SM0)
Weight @ Sched 2 (SM0)
Weight @ Sched 1 (SM1)
Weight @ Sched 2 (SM1)
Sum of weights: 3+0+6+12 = 21
0*4 + 0*3+3*1 + 0*1 = 3
0*4 + 0*3+3*0 + 0*1 = 0
0*4 + 2*3+3*0 + 0*1 = 6
0*4 + 4*3+3*0 + 0*1 = 12
Throughput steps for distribution
21(steps) * (3/21)=3 steps (~22Mbps)
21(steps) * (0/21)=0 steps (~0 Mbps)
21(steps) * (6/21)=6 steps (~43 Mbps)
21(steps) * (12/21)=12 steps (~86Mbps)
Remark 1: For each System Module, a maximum of two schedulers
are existing. Remark 2: There is existing a Minimum Throughput
rule, which means that the sum of throughput steps commissioned for
SM has to be at minimum the result value: Sum_Throughput_Min =
ROUNDDOWN (( Nbr_Non_MIMO_Cells per SM + 2 x Nbr_MIMO_Cells per SM
- 1) / 6) x 12 throughput steps + granularity_step; In case the
previously calculated throughput steps are not fulfilling that
rule, additional throughput steps will be assigned. The assignment
of the throughput steps needed to fulfill the minimum rule is done
by the BTS itself. Our example: SM1: Rounddown ((6 + 2 * 0 1)/6)*12
+ 3 = 3; SM0: Rounddown ((3 + 2 * 0 1)/6)*12 + 3 = 3;

What happens in case the throughput cannot be distributed evenly
?Lets have 3 PS2 and 1 PS3, which means to distribute 21 throughput
steps. Example:

Calculation of throughput - based on weight distribution:

Sum of weights:12+0+6+4 = 16
0*4 + 4*3+3*0 + 0*1 =12

0*4 + 0*3+4*1 + 0*1 = 4
0*4 + 0*3+3*0 + 0*1 = 0
Throughput steps for distribution (should be)
21(steps) * 12/16)= 15.75 steps
21(steps) * (0/16)=0 steps (~0 Mbps)
21(steps) * (4/16)=5,25 steps

Remarks on HSUPA: This conversion results in 7 HSUPA processing
sets. For each LCG, # of processing sets is calculated. LCG1 gets 4
HSUPA processing sets (as SM1 supports 80 UEs) and LCG2 gets 3
HSUPA processing sets, as 72 users per cell enabled, but SM0 does
not support 80 UEs.
5.8 Information about conversion rules
There are existing pre-defined conversion rules, which can be
impacted via setting of dedicated parameters shown in chapter 5.2.
For HSDPA the number of processing sets is evaluated by mainly
checking type and number of schedulers (see chapter 8.2)
For HSUPA, the number of HSUPA processing sets is calculated by
checking the number of users or by assigning a predefined
number.
5.9 Behaviour in case of Flexi System Module Rel.1
The new BB concept has been introduced for Flexi Rel.2 onwards
and is not applied for Flexi Rel.1. In case of upgrading Flexi
Rel.1, the conversion tool is not needed to be applied, but it does
not harm if applied, as the conversion tool would not generate
output for Flexi Rel.1. In that case, during the upgrade, the Rel.1
BTS just sets the parameter numberOfR99ChannelElements to that
value, which equals the number of CEs, which have been available in
RU20. In case of mixed configuration (master Rel.1 and extension
Rel.2), processing sets are generated for the extension, if HSxPA
has been configured.
But it is important to note, that within WN6.0 an extension
module can be added without re-commissioning. In those cases where
re-commissioning has not been performed after extension module
insertion, the BTS SCF will not contain extension module
information. So even extension module is Rel.2 version the
-
TS-3GBTS-SW-148 Copyright 2013 Nokia Solutions and Networks. All
rights reserved. CONFIDENTIAL
APPROVED version 22.0 Page 33
conversion tool would not generate Processing Sets, which would
result that for those mixed sides no HSxPA would be
commissioned.
Due to missing information within the SCF, the following
algorithm has been implemented: 1) Sites having FSM Rel.1 as master
system module and FSM Rel.1 as
extension module, no processing sets will be generated. 2) For
sites having FSM Rel.1 in SCF only, it is assumed that FSM
Rel.2
extension module is existing, if at least one of the following
HSPA+ features have been enabled:
- RAN 1686 HSPA 72 Users Per Cell - RAN1643 HSDPA 64QAM -
RAN1470 2ms TTI
These HSPA+ features are controlled by RNC, but can be enabled /
disabled on cell level and BTS level
Consequently these features can be disabled for all Flexi Rel.1
(as these are anyway not supported by Flexi Rel.1).
In case of proper configuration (not configured for Flexi Rel.1
), no Processing Sets are generated
Otherwise Processing Sets will be generated for Flexi Rel.1 -
does not harm, but uses Processing Sets and Rel.99 CEs from the
pool.
This can be compensated via providing extra / additional Rel.99
CEs and processing sets
As additional option, in case it is sure that no extension
modules have been inserted online within WN6.0, we have a parameter
PS_Rel_1 (on/off), which can be set to off.
- In that case no processing sets will be generated for FSM
Rel.1, but on the other hand there will be no PS set generation in
case of online FSM Rel.2 extension.
In case a Rel.2 extension module has been added in WN6.0 without
re-commissioning, but none of the features above has been
activated, the conversion tool will not generate processing sets.
In that case, the WN7.0 BTS needs to be commissioned with HSxPA
after having upgraded to WN7.0
In case of doubts, if online inserted extension modules are
existing or not, it recommended to run the conversion having set
the parameter PS_Rel_1 = on.
5.10 NetAct cleanup script
The NetAct License Manager command line interface is used to
cleanup the unnecessary license after WBTS upgrade. The conversion
is aimed to replace licences supporting RU20s/I-HSPA Rel.3 baseband
by licences for RU30s/ I-HSPA Rel.4 baseband. The NetAct cleanup
returns capacity to the NetAct pool, removes NMS licences from the
NetAct Licence Manager and also deletes no
-
TS-3GBTS-SW-148 Copyright 2013 Nokia Solutions and Networks. All
rights reserved. CONFIDENTIAL
APPROVED version 22.0 Page 34
longer needed licenses from BTSs. This is an optional step to be
performed and only should be performed when it is ensured that no
rollback is required. Input for that script is the XML file from
the RU30ConvTool containing a list of BTSs the conversion should be
performed. Licenses which are cleaned up are:
RAN1034 Shared HSDPA Scheduler for Baseband Efficiency (no
longer needed for Flexi Rel.2)
RAN912 Licence Based BTS Channel Capacity (no longer needed at
all)
RAN 912 licenses are cleaned up for both Flexi Rel.1 and Flexi
Rel.2 and licenses for RAN1034 are cleaned up for Flexi Rel. 2
only. In case of mixed BTS configurations (BTS contains both Flexi
Rel1. and Flexi Rel.2), RAN1034 licenses are not cleaned up.
Note 3: The cleanup script only should be applied for BTSs,
which have been upgraded successfully.
5.10.1 Steps of the cleanup procedure
The cleanup procedure consists of two steps: - first cleanup of
license manager data base and repository and then deletion
of licenses from WBTSes. During the conversion phase the NetAct
Licence Manager searches for NMS licences for the given list of
WBTSes. The capacity allocated for those WBTSes is returned to the
NetAct pool.
- Second step deletion of the NMS licenses from the WBTSes. This
step should be triggered manually after the WBTS migration is
completed. Opfiles are created by the conversion tool. The default
directory for the opfiles is $HOME/lic_conversion_opfile. The
opfiles can be executed with license manager command line tool.
How to call consecutive steps of the NetAct cleanup:
Using liccuimx run the conversion step by typing in command
line:
liccuimx -op licenceConversion inputFile
-deleteFromNEs T
Note: option deleteFromNEs causes creation of delete operation
files. The opt files will not be executed automatically!
Run licconvdelmx.sh to delete license files from BTSes:
licconvdelmx.sh

In the case shown above licconvdelmx.sh uses a default directory
with opfiles (i.e. $HOME/ lic_conversion_opfile). Optionally path
to directory containing operation files can be given as an input
parameter:
licconvdelmx.sh
After successfully finished delete operation particular opfile
is removed from the directory.
6. NOTE
6.1 Questions & Answers
Q1: What happens in case conversion is done in day x but SW
upgrade is done one week later ?
A1: After the conversion no configuration tasks impacting the
baseband (e.g. modifying # Channel Elements, modifying BTS
schedulers, modifying # users, modifying HSxPA configurations)
should be performed. In the final step of BB conversion the SCFs
are downloaded to the BTS. The BTS stores the new RU30 baseband
parameters but these parameters are not becoming active. As soon as
the upgrade is done the parameters will become effective. In case
of long time difference between conversion and upgrade of the BTS
having BB changes in between it is recommended to run the
conversion tool again and repeat steps 1-5 of the description
above.
Q2: What happens in case of BTS resets, before the BTS is
upgraded to RU30 ?
A2: There is no impact for the BTS BB conversion procedure
Q3: What happens in case of fallback to RU20 (WN 6) for an
already upgraded BTS ?
A3: When SW is downgraded back to WN6, BTS will use the WN6 SCF,
which means RU30 specific parameters are no longer used after BTS
fallback. RU30 licenses, already downloaded to the BTS are ignored
and the BTS continues to operate in RU20 as before.
If the WN6 BTS is required to be upgraded again to >= WN 7.01
and the BB configuration has been changed, the RU30ConvTool is
needed to run again and the newly converted parameters have to be
downloaded before the next upgrades attempt to WN7.0
Q4: When spare parts are replaced and BTS is already running on
WN 7.0. Has the conversion to be executed?
A4: No, in that case, conversion is not needed to be performed.
When the BTS is running with WN7.0 SW (conversion has been
performed earlier) it means
-
TS-3GBTS-SW-148 Copyright 2013 Nokia Solutions and Networks. All
rights reserved. CONFIDENTIAL
APPROVED version 22.0 Page 36
that the commissioning file already contains all WN7.0
parameters that were generated by the conversion tool.
Now when FSM is replaced with another one, usually operator
stores the SCF from old FSM before removing the FSM. After the new
FSM has been added and the WN7.0 SW has been downloaded/activated
to the new FSM, the commissioning file stored is added to new FSM
(e.g. using planned commissioning applying BTSs site manager). The
sequence to be performed is consistent with the sequence that has
been used in previous releases (as WN6.0).
Q5: The conversion tool provides the Rel.99 CE consumption. How
to know, how many LKs are needed to be ordered?
A5: As RU20 does not have a configuration parameter (#CEs), and
as the conversion tool is based on configuration parameters, it
cannot report the number of Rel.99 CEs needed for RU30. It
calculates the Rel.99 CE consumption. The information about the
number of CEs to be ordered can be obtained in the following
way:
a. Check number of existing CEs @ RU20s BTSs which easily can be
retrieved by using Netacts license manager
b. Calculate: # Rel.99CEs@RU30 (to be ordered) = CEs @ RU20s
BTSs Rel.99 CE consumption calculated by the tool
Example:
a. Check number of existing CEs @ RU20s BTSs by using Netacts
license manager.
b) Run conversion and then calculate: #Rel.99 CEs to be ordered
for RU30 = value from a) - Rel.99 CE consumption calculated by the
tool

APPROVED version 22.0 Page 37
Q6: During the conversion a SCF is generated by NetAct, which is
used by upgrading the BTS from WN6.0 to WN7.01. In case of a
rollback, the previous SCF applied for WN6.0 is taken into use
again. If now after some time the conversion is re-executed, a new
SCF is generated. How can these SCFs be differentiated and how can
it be ensured that wrong SCF is applied in the 2nd upgrade ?
A6: The SCF is generated by NetAct and has the following syntax:
SCF_.xml, where version is the NetActs plan id.
In case of an already existing SCF,a new conversion results in a
new SCF, where version has been increased by 1: SCF_N.xml ->
SCF_N+1.xml.
If after the rollback, it is not likely to upgrade in next time
to WN7.01 again, previously generated SCF_N.xml can be deleted.
Q7: Why is needed NetAct OSS 5.4 CD1 and do you have some more
background.
A7: NetAct OSS 5.4 CD1 is needed to ensure that all conversion
tools output parameters are supported. The support of the
parameters shareOfHSDPAUser, shareOfHSUPALicences has been
introduced as an conversion tools extension and requires dedicated
NetAct support. Otherwise import to NetAct of the XML file
generated fails. These parameters are supported in NetAct OSS 5.4
CD1 but also in some versions of OSS5.3 CD3. To check, if these
parameters are supported, please apply the procedure as described
below:
DS server: rpm qa|grep CMDBTC example: [racuse11@enest ~]$ rpm
-qa|grep CMDBTC Nokia-RAC-CMDBTC-DB-5.0-5.50.23-1
Nokia-RAC-CMDBTC-DB-5.0-5.50.25-1
-
TS-3GBTS-SW-148 Copyright 2013 Nokia Solutions and Networks. All
rights reserved. CONFIDENTIAL
APPROVED version 22.0 Page 38
[racuse11@enest ~]$ NetAct adaptation version must be
higher/equal Nokia-RAC-CMDBTC-DB-5.0-5.50.25-1
If the parameters shareOfHSDPAUser, shareOfHSUPALicences are not
needed to be part of the output XML, via cml the output generation
can be switched off. But in general its recommended to generate
these parameters as that ensures settings related to RU20s
configuration otherwise the share would be 50%/50%. In case of 1LCG
used, these parameters are not relevant.
In addition, OSS 5.4 CD1 does not require any 3G SCF Mgmt
license to export all objects needed.
Q8: What happens, if the conversion tool is not applied in BTSs
upgrade ?.
A8: If the conversion tool has not been applied, then no
processing sets will be configured. Consequently the BTS will not
be able to perform HSxPA.
# Rel.99 CEs @RU30 = # CEs@RU20
6.2 Estimated time running the conversion
The time running the conversion for all BTSs of a RNC cluster is
estimated by 1h. This includes the steps for uploading BTS and RNC
data, exporting BTS and RNW data into the tools input XML file ,
executing the conversion tool, importing back tools generated XML
to NetAct and downloading SCFs to the BTS, before executing the SW
upgrade from WN6.0 to WN7.0. This time is an average value and can
vary - mainly impacted by the steps for extracting and importing
the data and the number of BTS to be converted. For that time
estimation we consider an average size of 150 200 WBTS connected to
the RNC.

This file is to translate the xml file for conversion tool.
8.2.4 Case 4 - RNW parameters are not in export file
In this case, if one BTS only has BTSSC parameters in the export
file, then the BTS would not be converted by the tool.
So if you get thas problem, please check if the RNW parameter
upload has been successfully.
8.2.5 Case 5 - R99 CE set to zero after upgrade to WIN7.0
Example. We have 300 channel element license in WN6.0. But the
CE consumption calculated by convert tool is 420. That means after
the upgrade:
# Rel.99 CE licenses @ WBTS7.0 = 300 - 420 = -120
When BTS asks for related licenses, # Rel.99 CE licenses to be
requested==0.
This may happen, in case of HSxPA consumption parameters having
values, resulting in very high consumption.
Those consumption values are commercial values to be agreed
between customer and CT.

If all of those objects have been selected and the conversion
still does not produce output (in the output XML all values for
processing sets are set to the value 0), a reason may be that
LCELG:lCelIdList has not been exported.
This may happen, if the NetAct license 3G SCF Mgmt license is
missing. In that case install the license, make a new upload and
then perform a new export.
