Impacted Modules A9155 module

4.2 RMS: Dummy neighbours in cyclesThere is one limitation in declaring dummy neighbors in thefield: 32 different BCCH. Therefore in networks where the BCCHband contains more than 32 frequencies, the final interferencematrix may not be complete, since some frequencies are notscanned.

Feature Description


9/49


The solution is to have the possibility to create several cycles ofdummy neighbor, in order to cover the whole band andimplement then in cycles.

Impacted Modules A9155 module, RMS module

4.3 RMS: RMS interference formula calculationThe current formula of interference probability is performed oneach cell basis, with no correlation between cells. Therefore theRMS interference matrix cannot be mixed with predicted one,due to different approach. The formula has been tuned andcalibrated accordingly and can be mixed with the predicted one.

Feature Description

Another aspect is the absolute value of the RMS interferenceprobability which is much lower than the predicted interferencematrix. In order to mix them with equal weighting factors theRMS interference matrix has to be calibrated.


4.4 RMS: RMS co-channel interferenceThe RMS files used for the interference matrix creation areproviding the C/I information only for cells using differentfrequencies. Therefore the final interference matrix may beuncompleted. The solution is to compute the co-channelinterference matrix, as well, out of RMS files.

Feature Description


4.5 RMS: Neighbour clean-upUsually the neighbors in the network are increasing with time.This is mainly due to the network densification without revisingthe neighborhood plan. An increased number of neighbors is notrecommended especially in a frequency planning campaign dueto:

Feature Description

Impossible to solve all the necessary channel separationbetween neighbors

Too many neighbor leaves low space for declaring dummyneighbors, for RMS FP

Up to now there was no method developed to optimize theneighbor plan, only one method to create one out of predictions.

This feature will propose a method to delete the unnecessaryneighbors based on different inputs:

T180 statistics RMS Predictions Inter-site distance


10/49



4.6 RNP2OMC InterfaceFeature Description The RNP2OMC Module is the interface between A9155 V6 tool and

WiMAX OMC and is used by network planers to import and

export data to/from A9155 V6.

4.7 IPlanner InterfaceFeature Description IPlanner is the interface between A9155 Radio Network Planning

tool and the UMTS OMC and is used by network planers to export

data from A9155 V6 RNP tool.

IPlanner exports all specific fields in DRF XML format compatible

with WPS Access V3.1 and WPS Access V4.1RNC.

The DRF (Data Request Form) is an exchange functionality for

RNS parameters setting. It covers the creation, extension and

optimization steps of network configuration. Despite it can be


11/49


used for unitary purposes, its main interest is massive

configuration.

IPlanner exports all specific fields in CP XML format compatible

with WPS Access V4.2.

The CP XML format is an XML document format used to describe

the configuration of network element resources. This file formatis used to export from iPlanner and import into the WPS Access

tool in order to set/retrieve the cell planning configuration.

Impacted Modules A9155 core application, UMTS module

5 Maintenance FeaturesDue to the maintenance contract between Alcatel-Lucent andForsk [2], there are several features that are implemented in

new releases on request of Alcatel-Lucent or due to general

requests from other customers of Forsk without an official and

single ordering of Alcatel-Lucent. In meetings held with Forsk

those features have been synchronized with the features

requested by Alcatel-Lucent internal and external users.

5.1 File PropertiesFeature Description The version and build number of A9155 that is used to last save

an A9155 document will be stored in the properties of each

A9155 file. The user will find out what version and build was

used to the last save any A9155 document by right-clicking it in

Windows Explorer, selecting Properties from the context menu

and clicking the Advanced button on the Summary tab.


5.2 A9155 License managementFeature Description A9155 will display information about the time remaining on a

Administrator by blocking access to the licenses on a floating

license server.


5.3 Autosave CapabilitiesFeature Description A9155 V6.6 will be able to automatically save each open


12/49


document at a defined interval of time. In order to make

autosave backups of documents they will have to have a file

name assigned first.

For each document, A9155 will create an autosave backup file

(filename.atl.backup) in the same working folder as the original

ATL file and will autosave backup file from time to time.

The autosave configuration properties will be available using theFile option of the Menu bar and will allow the

activation/deactivation of the autosave feature and setting the

interval of time between successive saves.

Impacted Modules A9155 core application

5.4 Geo Data Formats improvements Coordinates system information will be imported in MapInfo

(MIF and TAB files) and ArcView (SHP//PRJ) files. This feature

will be activated by using the initialization file atoll.ini andwill define the mapping between the coordinate system in

A9155 and the coordinate system defined in the header files

of MapInfo(.MIF) and ESRI(.prj) vector files that will be

imported.

Feature Description

When importing files in ArcView format*SHP/PRJ), A9155 willuse the information from a SHX file, if it exist, to complete

any missing information from the PRJ file.

A9155 V6.6 will allow to import and export BIL and VerticalMapper (GRD and GRC) files larger than 2Gb.

A9155 V6.6 will support the import and export of vectorobjects in TAB file formats.

5.5 Database management improvementFeature Description A9155 V6.6 will allow the creation of sets of custom database

fields.

When custom fields will be added to tables, it will be possibleto define the group that will have access to them. The name of

the group will be specified by a separate column in the Custom

Fields table.


13/49


When a user will open a document from a database, he willhave the possibility to select which set of custom fields he

accesses. A list with the names of the groups defined for the

custom fields of the database will be displayed. This will allow

users to have access to the database fields they need while

reducing the use of computer resources.

It will be possible to define a name and a legend entry for eachfield. The name will appear in the database and the legend entry

in the ATL file. For the legend entry a new field Caption will be

added in the Custom fields table.


5.6 Archiving Data in database using transactionsFeature Description A9155 will support transactions for archiving data to database.

This approach ensures that users will always get consistent data

when refreshing from database, even when another user isarchiving his modifications.

This feature will be activated using a new line in Atoll.ini file:

[Database]

UseTransaction=1


5.7 Exporting to MS Access 2000 formatFeature Description A new option in the Atoll.ini file will allow A9155 V6.6 to export

radio network data to MS Access 2000 format. By default, A9155will export the radio network data in MS Access 95 format.

The following line will be added in atoll.ini to export radio

network data to MS Access 2000 format:

OLEDB_EngineType=5


5.8 Using site lists to archive dataFeature Description In A9155 V6.6, it will be possible to select a site list from the

project when archiving data from the work project to the master

database. A new option Site list will be added to the list ofTables for Archive dialog. By selecting the sites list the data to

be archived will be restricted to the sites included in the sites

list.

It will be possible to retrieve the primary key fields names,

necessary when importing and exporting using the API.

Planning tools for optimizing network parameters.Impacted Modules A9155 core application

5.15 Displaying the Path-loss Matrices When viewing the path loss matrices for a project, it will be

available the option of viewing all the path loss matrices or

only the invalid path loss matrices. When updating a large

project, this will give a rapid overview of both the number of

invalid path loss matrices and the causes for invalidity.

Additionally, the user will view a summary of the causes forinvalidity and the number of transmitters for each cause.

Feature Description

A9155 V6.6 will display the reason for invalidity in the EventViewer of each path loss matrix before recalculating it.

When saving a document under a new name using the Save Ascommand, a new option will let you to save copies of the

corresponding path loss matrices.


5.16 Neighbours improvementFeature Description It will be possible to start automatic neighbor allocation on a

single transmitter.

When opening or creating a document from a database, the user

will have the option to select whether to load intra or inter

technology neighbors, both or neither.


5.17 Support of multiple zonesFeature Description In A9155 V6.6, it will be possible to import MapInfo files with

several polygons as computation, focus or filtering zone. Inprevious versions, only a single multi-contour polygon was

supported.


5.18 Coverage export zoneFeature Description In A9155 V6.6, it will be possible to create a coverage export


16/49


zone in order to export a defined part of coverage as an image

file.

The coverage export zone could be created by drawing it or by

importing it from a vector file. As well, the coverage export zone

could be exported to a file to be used in other projects and other

applications. All the functions that are available for the other

zones (Computation, Focus, Filtering zones), will be available forcoverage export zone.

The coverage export zone will be manageable in Zones folder

(Geo tab) in the same way as the other zones (Computation,

Focus, Filtering zones).


5.19 Common resolution for Coverage PredictionsFeature Description It will be possible to create coverage predictions that will always

take the default resolution set in the Predictions properties. Thiswill allow the user to redefine the resolution of a series of

coverage predictions without having to charge it in each

individual coverage prediction. The user will activate this

feature by adding a new line in atoll.ini file:

[Studies]

SpecifyResolutionAfterComputation = 0.


5.20 Live Traffic DataFeature Description When importing live traffic data, e.g. traffic maps based on

transmitters and services, A9155 V6.6 will filter out and list only

downlink is segmented or not, by checking or un-checking a

special box in frame configuration.


12.5 Defining Permutation ZonesFeature Description In A9155 V6.6, for a WIMAX 802.16e network, it should be

possible to define different permutation zones for different

frame configurations.

The parameters related to permutation zones will be:

o Zone Numbero Subchannel Allocat ion Mode: The subchannel allocation

mode used by the permutation zone. Subchannelsallocation modes could be selected from the list: PUSC,FUSC, OPUSC, OFUSC, AMC, TUSC1 and TUSC2.


38/49


o Number of Used Subcarr ier s: The number of subcarriersused for transmission. This number includes the pilot anddata subcarriers.

o Number of Dat a Subcarr ier s:The number of subcarriersused for data transfer.

o Number of Subchannels per Channel: The number ofsubchannels in the channel.

o Subfr ame:downlink or the uplink subframe.o Qualit y Threshold (dB): The minimum signal quality

required for a user to be allocated a permutation zone.o Max Speed (km/h): The maximum vehicular speed

supported by the permutation zone.o Max Dist ance: The maximum distance from the base

station covered by the permutation zone.o Pr io r i t y : The priority of the permutation zone in terms

of its allocation to a user.o Ant enna Diver sit y Support :Select the type of antenna

diversity technique supported by the permutation zone.o Secondary Groups Used: For segmented frame

configurations using 1024 and 2048 total subcarriers,select which of the secondary subchannel groups (1, 3, 5)are used by the PUSC DL permutation zones.

Sub-channels allocation modes with higher pilot subcarriers

densities, such as PUSC, will be assigned to users at high speeds.

When assigning users to allocation modes such as the AMC zone,

Radio Resource Management algorithm of WiMAX module should

consider also the user equipment capabilities. Only user

equipment capable to work with AAS (Adaptive Antenna System)

will be assigned to the AMC zone.


12.6 Limitation by distance for permutationzones

Feature Description In A9155 V6.6, it will be possible to define the maximum

distance from the base station covered by the permutation zone.

The allocation of permutation zones to users (mobiles,

subscribers or pixels) will be based on a distance criterion in

combination with the quality and speed criteria.


12.7 Antenna diversity techniques at permutationzone level

Feature Description Permutation zones will support several antenna diversity

techniques.

The following antenna diversity techniques will be supported:

Adaptive Antenna Systems (AAS)


39/49


Spatial Multiplexing (SM) Space Time Transmit Diversity (STTD) Adaptive MIMO Switching (AMS)

Each permutation zone will support one or several different

antenna diversity modes. It will be possible to select Standard,

AAS, SM, STTD, AMS, Standard+AAS, Standard+SM, Standard+STTDor Standard+AMS.


12.8 Allocating secondary sub-channel groupsFeature Description For a segmented PUSC zone, it will be possible to allocate

secondary sub-channel groups (1, 3, 5) for frame configurations

using 1024 or 2048 total subcarriers. The primary sub-channel

groups (0, 2, 4) will be determined directly from the preamble

index and the segment number.


12.9 Defining WiMAX radio bearersFeature Description WiMAX radio bearers carry the data in the uplink as well as in the

downlink and in A9155 it is synonymous with MCS, modulation

and coding schemes.

In A9155 V6.6, for a WiMAX 802.16e network, it will be possible

to define different WiMAX radio bearers.

For each WiMAX radio bearer several fields should be set:

Radio Bearer Index Name Modulation selectable from a list of four modulation types:

BPSK, QPSK, 16QAM and 64QAM;

Coding Rate Bearer efficiency (bits/symbol) number of useful bits

transmitted over a symbol


12.10 Defining cell output powerFeature Description In A9155 V6.6, WiMAX projects, modelling cell output power will

be enhanced with several fields:


40/49


Pr eambl e Power (dBm) representing the cells transmissionpower over the preamble of the frame

Traf f i c power of f set (dB) that will be subtracted from thepower defined in Power (dBm) field to determine the

transmission power of the traffic sub-carrier during the

loaded part of the frame.

Pi lot power of f set (dB) that will be subtracted from thepower defined in Power (dBm) field to determine the

transmission power of the pilot sub-carrier during the loaded

part of the frame.

Id le Pi lot power of f set (dB) that will be subtracted fromthe power defined in Power (dBm) field to determine the

transmission power of the traffic sub-carrier during the empty

part of the frame.


12.11 WiMAX station templatesFeature Description With A9155 V6.6, for WiMAX 802.16e networks, it will be possible

to define a specific WiMAX station template with parameters

grouped in three tabs:

General where you can specify parameters like nameof the station template, antenna specific parameters,

smart antenna parameters, propagation settings.

Transmit ter with transmission/reception specificparameters

WiMAX with cells related parameters. Theseparameters will be used for creating the related cell in

Cells table.


12.12 Neighbour allocationFeature Description With A9155 V6.6, for WiMAX 802.16e networks, it should be

possible to define neighbours manually.

A9155 will support t
