tools which make these operations easier and more effective. The main objectives of CNA

are as follows:

To maintain a comprehensive picture of the cellular network

To support a functional view of the cellular network and hide its implementation

To reduce the need for user intervention when transferring configuration parameters

to the NEs (Network Elements)

To provide a user friendly interface

To maintain the data in the OSS-RC (Operations Support System Radio and Core) , in

order to minimize the time to access data and the load on the NEs

To simplify maintenance and management of the cellular network by input of consistent data to the NEs

This document is intended for users of the CNA application in OSS-RC.

It is assumed that the reader of this document:

is familiar with Sun workstations and window-based computer interfaces

is familiar with OSS-RC

is familiar with UNIX command line interfaces

The typographic conventions for all CPI in OSS-RC is found in Reference [2].

CNA manages cell and cell related data in a GSM (Global System for Mobile communication)radio network. This includes functions which support addition of cells, modification of data

in existing cells and deletion of cells from the network, for a detailed description seeReference [3].

The cell related objects and data in the connected MSCs (Mobile services SwitchingCentres) and BSCs (Base Station Controllers) are controlled through a number of MOs(Managed Objects) in CNA keeping the data in persistent storage. The user manipulates theparameters of the MOs using a user friendly interface when adding to or changing thelogical configuration of the cellular network. The corresponding information in the valid

area can be adjusted when the data of an object in the network has been changed in CNA.

The user may also use the GCC (Graphical Cell Configuration) application to display thenetwork model superimposed on a geographical map provided by GNIP (Geographical andLogical Network Information Presentation), provided that GCC has been connected to bothCNA and GNIP.

All changes to the network are initially performed in a planned area, which is later used toupdate the valid area and the real network.





The updat e function compiles the parameters of the MOs to AXE commands. The

parameters of the NEs (Network Elements) are updated when the commands aretransferred to them.

The consi st ency check function checks the MOs for consistency in order to minimize

errors in the parameter settings of the cellular network.

The MOs can also be adjusted with the data in the network.

The On-Line Help provides brief operating instructions. It also contains warnings of risks,explanations of abbreviations, short-cuts and references to more general information.

CNA comprises the following functions and tasks:

Information Retrieval

Adjustment

Fallback area handling

Log area handling

Planning

Update

Consistency check

CNA Management

Error handling

Graphical User InterfaceCommand Line Interface

By means of the CNACMI (CNA Command Line Management Interface), it is possible for theuser to perform configuration management and job management tasks. For more

information about CNACMI execute the command man CNACMI .

By means of CNAUICMI (CNA User Interface Command Line Management Interface), it ispossible for the user to start application window CNA Table without starting the CNAapplication. For more information about CNAUICMI execute the command man CNAUI CMI

The following needs to be true before CNA can be used:

All cells belonging to an MSC and the Ericsson BSCs connected to the MSC must bemanaged by the same OSS-RC

All cell names, BSC names and MSC names managed by CNA must be unique

The name of a certain cell must be the same in all MSCs and BSCs where dataconcerning it exists

GPI (GERAN Plugin) and BSM (Base Station Management) need to be installed to

support synchronization of the CNA valid area and ONRM (Object Network ResourceModel)

Application management user actions require that the user is an application





administrator

A CNA user is granted authority for one user category, only. CNA uses the aut hor i t y

dat abase to check authorities. The authority management is taken care of by TSS

(Telecom Secruity Services). The TSS checks that the user is authorized to run, forexample, an updat e or an adj us t ment job.

The operator must receive an authority profile from the authority database in order toprevent unauthorized access to certain functions. The database contains the definition of the three subprofiles: Aut hor i t y Type, Act i vi t y Set , and Ti me Pr of i l e.

A user may have authority to run CNA updat e and adj us t ment jobs without having

authority to use the MML commands for the current job. In Table 1 this is identified by thesymbol (x), indicating that the authority to use MML commands may be granted to someoperators but not to others.

The following user categories are supported:

The system administrator has full access to all functions and processes in the system, and

is the system body providing other users access as required and appropriate.

SYSADM System Administrator

APPLADM application administrator

The I nf or mat i on Ret r i ev al function is used to examine the cellular network structure

and data as stored in the valid area.

This function includes the following:

View the valid area through the GCC and inspect the relations between objects in thevalid area

Inspect the properties of the MOs in the valid area

Print out the properties of the MOs in the valid area or save them in a file

The adjustment function is used to compare the valid area with the cellular network and toadjust the valid area model. The valid area and the real network are compared when anadjustment job starts. The valid area is then updated with the differences found and thusbecomes a true copy of the network.

The following objects are not adjusted: foreign cells, RNC (The Radio Node Controller NE in

the UMTS network), UTRAN (UMTS Terrestrial Radio Access Network) cell, MSC of versionOTHER, BSC of version OTHER, and subordinate objects to these objects.

It is possible for the user to:

Adjust the MOs in the valid area with data in the network

Adjust on valid area level, see Section 3.2.1

Adjust on MSC level, see Section 3.2.2

Adjust on BSC level, see Section 3.2.3

Adjust on cell level, see Section 3.2.4

Adjust on cell level on one or several cells at a time

Adjust on all levels with check only. The differences are listed but no data is adjusted

in valid area

Start adjustment of the valid area immediately or with delayed activation

Select if the job should be run once or repeatedly

Delete queued, terminated, failed and completed adjustment jobs

Delete several adjustment jobs simultaneously

Terminate an active adjustment job

Open an adjustment job report window

When starting an adjustment of the valid area, decide to terminate the adjustment job or continue with the next command in the event of error messages from the NEs.Occurring errors are saved in a log file

Use MMLcommands

(x) (x) x





Select whether the valid area should be saved in a fallback area (see Section 3.3 )

before the adjustment begins

Supervise the status of a running adjustment job in a separate window, from whichreports may be viewed and printed

Set default values for adj us t ment j ob options

Synchronize the CNA valid area and ONRM using a command line interface (optional)

The adjustment function performs the following:

Marks MOs in the valid area which have been changed with the date and time of the

adjustment

Marks new areas with the user ID and the date and time of creation

Changes the user ID and the date and time indication for an area in which an objecthas been changed. This concerns all areas

Creates and executes the AXE commands needed to read the data in the NEs

Retries sending commands to the NE if the command is not executed on the first trydue to FUNCTI ON BUSY. The number of retries and the intervals are defined as system

parameters. The user can select if the adjustment shall terminate or continue withthe next NE if the limit is reached

Terminates the adjustment or continues with the next NE (user selectable) and issuesan error message if an NE indicates that cell data changes are in progress duringcollection of data from the network

Terminates the adjustment or continues with the next command (user selectable) forthe current NE in case of an error reply from the current NE. The error is saved in a

log file

Generates a report which lists all the differences between the valid area and the

network. The report can be displayed before, during or after the adjustment has beencompleted. It can also be printed and saved in a file when the adjustment iscompleted. The report includes the printout commands which have been executed.

Any error replies from the NEs are also included

Notifies the user when an adjustment is finished or terminated

Runs and completes without needing any manual assistance

3.2.1 Adjustment of the Valid Area

The valid area is the current selection in CNA, the following is then adjusted:

all MSCs belonging to the valid area with the NE data, unless the MSC is of versionOTHER. See Section 3.2.2

all BSCs belonging to the valid area with the NE data, unless the BSC is of versionOTHER. See Section 3.2.3

3.2.2 Adjustment of the MSC

An MSC is the current selection in CNA, the following is then adjusted:

the MSCs with the NE data

Inner cells belonging to the MSC and their data with the NE data

outer cells belonging to the MSC and their data with the NE data





The following item may be adjusted separately with the NE data:

AXE file sizes

3.2.3 Adjustment of the BSC

A BSC is the current selection in CNA, the following is then adjusted:

the BSCs with NE data

internal cells belonging to the BSC and their data with NE data

neighbor relations belonging to the BSC and their data with NE data

UTRAN neighbor relations belonging to the BSC and their data with NE data

Overlaid subcells belonging to the BSC and their data with NE data

Channel groups belonging to the BSC and their data with NE data

External cells belonging to the BSC and their data with NE data

Transceiver groups belonging to the BSC, and the internal cells or the channel groupsto which they are connected, with NE data

Priority profiles belonging to the BSC and their data with NE data

Sites belonging to the BSC with NE data

Note: In CNA preferences it is chosen whether the EMG (Extension Module Group)or the RSITE (RBS site) name should be used as site names in the valid area

(application administrator only)

The following group of items may be adjusted separately with NE data:

The state (active, halted) of internal cells and channel groups in the BSC

AXE file sizes

Optional features

3.2.4 Adjustment of a Cell

An internal cell is the current selection in CNA, the following is then adjusted:

the internal cell data with NE data

corresponding inner cell data with NE data

neighbor relations belonging to the internal cell and their data with NE data

UTRAN neighbor relations belonging to the internal cell and their data with NE data

overlaid subcells belonging to the BSC and their data with NE data

channel groups belonging to the internal cell and their data with NE data

The state (active, halted) of the internal cell and channel groups belonging to theinternal cell

The fallback area handling provides the means of restoring the data in the network to the





contents it had at the time of creating the fallback area.


List all fallback areas

Back up the data in the valid area in a fallback area. There may be several fallback

areasInitiate a backup to a fallback area directly or before an adjustment of the valid areaor an update with a planned area is started

Inspect the relations between objects in the fallback areas

Inspect the properties of a fallback area and its MOs

Print lists of MOs in the fallback areas and their properties or save them in a file

Create a planned area which is updated with the differences between a fallback areaand the valid area. An update with this planned area restores the network to thestate it was in when the fallback area was created

Remove fallback areas which have been locked by the current user

The log area handling provides the means of storing BSCs, internal cells and theircorresponding channel groups in a log area. Log areas are created through the RNR (RadioNetwork Recording) application.


List all log areas

Inspect the properties of a log area and the properties of the MOs in the areaPrint lists of MOs and their properties in a log area or save them in a file

Remove log areas when they are locked by the current user

The Planning function is used to create, modify, and delete MOs in a planned area.

A planned area is a model of the valid area where changes can be tested before they areapplied to the network. The planned area does not affect data in the valid area and the

network until the user updates the valid area with the planned area.

3.5.1 General Planning of Objects

When doing ordinary planning such as creating new objects the following can be done:

Create planned areas

Create, modify and delete MOs in a planned area which is locked by the current user

Lock and load a planned area at creation

Make a copy of a planned area and its contents

List all planned areas

View geographical location of cells or sites using GNIP





Inspect the properties of a planned area and the properties of the MOs in the area

Print lists of MOs and their properties in a planned area or save them in a file

Add the following objects (all objects) to a planned area: MSCs, inner cells, outercells, BSCs, sites, transceiver groups, internal cells, external cells, UTRAN externalcell, overlaid subcells, channel groups, neighbor relations, UTRAN neighbor relation,RNCs, UTRAN cell, foreign cells, and priority profiles

Set initial parameter values for added objects according to Section 3.5.6

Mark the following objects for removal from the valid area and the network whenthey are updated with a planned area: inner cells, outer cells, internal cells, externalcells, UTRAN external cells, overlaid subcells, channel groups, neighbor relations,UTRAN neighbor relations, and priority profiles

Mark the following objects for removal from the valid area when it is updated with aplanned area (there is no communication between these MOs and the NEs):transceiver groups, foreign cells, objects under a BSC of version OTHER, RNC, andUTRAN cell

Clear removal marks in the planned area in the valid area of the following objects:

inner cells, outer cells, transceiver groups, internal cells, external cells, overlaidsubcells, channel groups, neighbor relations, foreign cells, priority profiles, UTRANexternal cell, UTRAN neighbor relation, RNC, and UTRAN cell

Remove the following objects (all objects) from a planned area if they do not exist inthe valid area: MSCs, inner cells, outer cells, BSCs, sites, transceiver groups, internal

cells, external cells, overlaid subcells, channel groups, neighbor relations, foreigncells, priority profiles, UTRAN external cell, UTRAN neighbor relation, RNC, andUTRAN cell

Note:MSCs and BSCs must be added and removed using the ARNE (Add RemoveNetwork Element) application. sites are added and removed using the BSMapplication and adjusted into CNA

Connect and disconnect channel groups from a transceiver group

Remove planned areas locked by the current user

3.5.2 Profile Object Handling

To make it easier to created several identical or almost identical objects profile objects canbe used. A profile object is a template object that stores all parameters that should beidentical for several objects.


Create, delete and edit internal cell, BSC, neighbor relation and overlaid subcellprofile objects

Reset modified and possible validated, but not yet applied, parameter values to the

value they had before they were modified

Print lists of profile objects and their properties or save them in a file

Select whether to see all profiles or to see all profiles for one type of profile objectonly

Set a parameter in a profile object to undef i ned

Note: Profile objects do not exist for objects of version OTHER. The system validates





modified parameter values before they are accepted.

3.5.3 Parameter Planning


Modify the parameter values in the following objects: inner cells, outer cells, internalcells, external cells, overlaid subcells, channel groups, neighbor relations, foreign

cells, priority profiles, UTRAN external cell, UTRAN neighbor relation, RNC, andUTRAN cell

Copy parameter values from the following objects in any planned area, fallback areaor in the valid area to the same type of objects in a planned area: inner cells, outercells, BSCs, sites, internal cells, external cells, overlaid subcells, channel groups,

neighbor relations, foreign cells, priority profiles, UTRAN external cell, UTRANneighbor relation, RNC, and UTRAN cell

Copy parameter values from the following objects in any log area to the same type of objects in a planned area: BSCs, internal cells, and channel groups

Copy parameter values from the following profile objects to the same type and

revision of objects in a planned area: BSCs, internal cells, overlaid subcells, andneighbor relations. Only parameters defined in the profile objects are copied

Restore values of individual parameters for the following objects in a planned area,that is, recover the value from the valid area: inner cells, outer cells, BSCs, sites,internal cells, external cells, overlaid subcells, channel groups, neighbor relations,

foreign cells, priority profiles, UTRAN external cell, UTRAN neighbor relation, RNC,and UTRAN cell

The system performs the following:

Marks modified parameter values in the planned area. See Section 3.13.1

Validates modified parameter values before they are accepted. See Section 3.5.7

Marks modified objects in a planned area with the date and time of the latestmodification

Stores the date and time of the latest modification of a planned area together with

the area. The information is displayed in the Area Properties window

3.5.4 MO Management at Planning

In a planned area It is possible for the user to:

Define that a change in an internal cell should be applied to all internal cells within

the same BSC

Move one, or several, or all internal cells connected to a site from one BSC to anotherBSC within the same planned area. All related MOs are affected

Assign new target cell names for moved internal cells. All related MOs are affected bythe name change.

3.5.5 MO Data Consistency at Planning

In planned areas, in order to help preserve the consistency of data stored in more than oneplace in the network, the system:

Automatically adds a corresponding inner cell when an internal cell is added





Automatically marks the corresponding inner cell for removal when an internal cell is

marked for removal

Automatically marks the neighbor relations belonging to it and the external cells, theouter cells and the neighbor relations which refer to it for removal when an internalcell is marked for removal

Automatically marks the UTRAN neighbor relations belonging to it, when an internal

cell is marked for removal

Automatically marks the overlaid subcell belonging to it for removal when an internalcell is marked for removal

Automatically marks the UTRAN external cell and UTRAN neighbor relations referringto it for removal when an UTRAN cell is marked for removal

Automatically marks the channel groups belonging to the internal cell or the overlaidsubcell for removal when an internal cell or an overlaid subcell is marked for removal

Automatically marks the external cells, outer cells and neighbor relations referring toit for removal when a foreign cell is marked for removal

Automatically creates the required External and outer cells when neighbor relations

are created, if they do not already exist

Automatically creates the required UTRAN external cell when UTRAN neighborrelations are created, if they do not already exist

Changes the corresponding parameters in the external cells, the inner cells and theouter cells with the same designation (in other BSCs and MSCs) if a subset of the

parameters in an internal cell is changed

Changes the corresponding parameters in the external cells and the outer cells withthe same designation (in other BSCs and MSCs) if a subset of the parameters in aforeign cell is changed

Changes the corresponding parameters in the UTRAN external cells with the same

designation if a subset of the parameters in an UTRAN cell is changed

Changes the corresponding parameters in the outer cells with the same designation(in other MSCs) if a subset of the parameters in an inner cell is changed

Automatically updates the BCCH (Broadcast Control Channel) Allocation active andIdle lists according to the neighbor relation data

Automatically updates the information in the UMFI (UMTS Measurement FrequencyInformation) active list and the UMFI idle list according to the UTRAN neighborrelation data

Note: It is possible for the user to: control the major distribution mechanisms in

CNA Preferences Window

3.5.6 Initial Parameter Values

Parameters are given initial values at the creation of an MO. The values are the same initialvalues the NE assigns the parameters at the MO creation in the NE.

In addition, some parameters in external cells and inner cells are initiated from thecorresponding parameters in internal cells or foreign cells where applicable. Parameters inouter cells are initiated from the corresponding parameters in inner cells or foreign cells.

Parameters in UTRAN external cells are initiated from the corresponding parameters in

UTRAN cells.

3.5.7 Parameter Validation





Parameters are always validated against the permitted value ranges when they are entered

in the planning function. The parameter ranges are adapted to the system type and versionof the MO.

The following objects are not updated: foreign cells, RNC, UTRAN cell, MSC of versionOTHER, BSC of version OTHER, and subordinate objects to these objects.

3.6.1 General


Perform more than one update session at a time, from one or several planned areas,

provided that they do not contain the same NEs

Start an update job immediately or with delayed activation

Delete scheduled update jobs

Terminate active update jobs. A new update job can be started on the planned areato continue the terminated update job

Decide to terminate the update job or to continue with the next command whenupdating the valid area in the event of error messages from the NEs. Occurring errorsare saved in a log file

Decide whether to save the valid area in a fallback area before an update job starts

Decide whether the update of the BA (BCCH Allocation) lists should be conditional or

unconditional before an update job starts

Decide to set all appropriate internal cells in one BSC to the HALTED state before any

individual internal cell is changed or to set the individual internal cells to theHALTED

state at the time they are to be changed. The internal cells or the channel groups areset to the HALTED state only if required when the valid area is updated

Make additional changes to a planned area after the network and the valid area havebeen updated from it

Add transceiver groups, foreign cells, RNCs, UTRAN cells, and OTHER internal cellsand neighbor relations from a planned area to the valid area or delete them from thevalid area using an update job. The update job does not add transceiver groups,foreign cells, OTHER internal cells or OTHER neighbor relations to the NEs

The update function performs the following function:

Issues an error message if an update job terminates due to an unrecoverable error

Sets the internal cells or channel groups to the state HALTED when updating the NEs if

this is required

Updates the network with the differences between the planned area and the validarea

Does not start the update job if the planned area contains any MSCs, BSCs or siteswhich do not exist in the valid area. In this case, neither the real network nor the

valid area are updated

Updates the valid area with the changes after each successfully executed AXE

commandMakes no changes to applicable data in the valid area if a command fails





The planned area still exists after the terminated update job if an update fails. A new

update job can be started on the planned area, and CNA retries to send the failing andremaining commands in the update job

It is not possible to modify a planned area while an update job with the planned area inquestion is in progress

3.6.2 Procedures for Updating the NEs

During an update the interaction with the NEs are as follows:

The data links connecting the OSS-RC to the NEs are checked before any data ismodified in the valid area and the NEs. The update job is not started if a link to anyof the NEs included in the update is out of order

CNA creates and executes the AXE commands needed to update the data in NEs to

match the changes

CNA creates and executes the AXE commands needed to direct the internal cells andchannel group to states in which the AXE commands containing the data can beexecuted

CNA creates and executes the AXE commands needed to connect channel groups to

the transceiver groups and to disconnect them from transceiver groups

CNA repeats the command a number of times and at system defined intervals if afatal communication failure occurs during the execution of the AXE commands

CNA repeats the command a number of times and at system defined intervals if acommand is not executed due to FUNCTI ON BUSY in an NE

If the command repetition fails due to a fatal communication failure, or FUNCTI ON

BUSY, or other error messages from the NEs, CNA continues with the next command

or terminates, depending on the setting when the update was initiated

An update report is compiled during the update process. The report can be displayedduring the update. The report may be printed or saved in a file when the update jobis finished

The result of the update of individual objects, such as Internal or external cells, is

added to the report when the commands have been executed. AXE commands andresponses are included in the report

The user receives an E-mail when an update job has been completed or terminated

CNA can perform consistency checks on the MOs in the valid area and the planned areas at

the following levels:

Area level: The consistency checks of MSCs and BSCs are performed for all MSCs andBSCs in the valid area

MSC level: The MSC itself and all the Inner and the outer cells which belong to theMSC are checked for consistency. The BSC consistency checks are performed for allBSCs belonging to the MSC

BSC level: All BSCs belonging to the same MSC and all MOs which are connected toor contained in the BSCs, including MOs related to these are checked for consistency

internal cell level: The internal cell itself, the external cells (with the samedesignation as the internal cell in all BSCs contained in the area), the inner cell(corresponding to the internal cell), the outer cells (with the same designation as the

internal cell in all MSCs contained in the area) and the neighbor relations, channel





groups and overlaid subcells connected to the internal cell are checked

The result is displayed, printed or saved in a file according to the set preferences

The job runs and completes without needing any manual assistance

It is possible for the user to do the following:

Select predefined check rules to compose a customized consistency check job

Save the selected check rules in a file to be used in later consistency check jobs

Select to run a reduced consistency check for an area, MSC or BSC respectively. In areduced consistency check , only the modified or new cells in the area, MSC or BSCand the cells having these cells as neighbors are checked. The neighbors to the

modified or new cells are checked as before. The reduced consistency check is usedto consistency check only parts of large scale modifications

Start a consistency check job immediately or delayed

Schedule a consistency check job to be run once or repeatedly

Decide if the checked object and the used rules shall be listed in the consistency

check job report

Set default values for consistency check jobs options

Display a consistency check job Properties window

Terminate an active consistency check job

Delete a queued, terminated, failed or complete consistency check job

Delete several consistency check jobs simultaneously

Open a consistency check job report window

Supervise the status of a running consistency check job in a separate window, fromwhich reports may be viewed and printed

PCP (Predefined Configuration Profiles) offers a way to create predefined parameterconfigurations in so called Configuration Profiles. A profile defines a specific configurationfor anything from a single parameter, several or all parameters of one or more features toa subset or all of the parameters for configuration of a specific type of MO, for instance anInternal Cell. Configuration Profiles that are intended for a common configuration purpose

are identified and grouped by the Profile Group to which they belong.

The use of Profile Groups and their associated Configuration Profiles provides obvious

benefits in the job of configuring the cell network but possibly even more so in the job of keeping track of and correcting unwanted changes to the configuration made without duecoordination with radio engineering.

The CNA application is managed by a application administrator. For the application

administrator It is possible for the user to:

Set CNA preferences

Unlock planned areas which are manually locked by other users

Terminate and delete scheduled update, adjustment or consistency check jobs ownedby other users





Clear locks of the valid area and MSCs, BSCs, RNCs, or foreign cells in the valid area

which have failed to be released due to OSS-RC system errors

3.10.1 Start

The CNA application is started from ONE (Object Network Explorer) or from theworkspace menu. The valid area is automatically loaded during the start procedure. The

user can select whether the GCC should also be started when CNA starts.

3.10.2 Shutdown

The CNA application session is terminated by closing the CNA base window.

Ongoing update, adjustment or consistency check jobs can be terminated in the userinterface. Information about job termination is contained in the job reports.

Processes can be terminated due to internal errors in the system. At uncontrolledtermination, a locked valid area and NE are not automatically correctly released, and jobreports are not concluded. See Section 3.9

Scheduled jobs are not deleted when the application is shut down or terminated.

The ONRM is the master database in the OSS-RC system. The flow of network topology

information is illustrated in the figure below.

Figure 1 Network Topology Information

GPI synchronizes the information between the CNA and BSM valid area and ONRM.

The following error handling is applicable for internal CNA errors:

When an internal error which cannot be handled by CNA is detected, the user is





informed, the error is reported to the OSS-RC error handling system, and the

execution of the CNA function concerned is terminated

Operations which are interrupted by an error do not resume execution after a restartof CNA


Saves data entry to the objects in the areas in the database each time the Applybutton is selected and recovers it if an internal error terminates a session

The CNA application is managed using either the Graphical User Interface or a Command

Line Interface.

3.13.1 General


Use scrolling lists for navigation between the objects in CNA. The scrolling lists are

accessible in the CNA base window

Select the desired object from a scrolling list. The scrolling list displays the names orobjects contained or known by the selected object in question. For example, all sitesbelonging to a BSC can be displayed in a scrolling list

Filter on the system type and hierarchical data for internal cells, external cells,

foreign cells

Select the operations to be performed on a selected object from menus

Display and change parameter values in Properties windows

Display Properties windows for several different MOs simultaneously

Display reports from the update, the adjustment and the consistency check jobs in

separate windows

Supervise the status of different update, adjustment and consistency check jobs inseparate windows, from which reports can be viewed and printed

Select the rules to be used in a consistency check in a separate window, and save theselections in a file

Set CNA Preferences in a window

The system performs the following

Automatically also selects an internal cell, a foreign cell, an overlaid subcell or a site

in GNIP if the MO is selected in the CNA base window, provided that GNIP isconnected

Marks parameter values which have been modified in a planned area in the PlannedArea Properties windows

Automatically converts any lower case text information which CNA requires to be

upper case

Note: When a Properties window is opened it is always up to date, that is, the data

is retrieved from the last save





3.13.2 CNA Table

The CNA Table function is intended for compact presentation in table form of all or parts of the various parameters used by the different MOs. The CNA Table also makes it easier to

change a parameter for several MOs.


Start CNA Table from the CNA base window, with one or more MOs of the same

Load objects from all existing area types in a CNA Table

Create, save, and load a collection of objects of a specific object type, referred to asobject sets. The user can save an unlimited number of object sets (CNA does notimpose any limitations, but there may be system limitations)

Switch to any of the existing object sets at any time

CNA Table can contain several MO types in a specific area

Add one or more Related object types to CNA Table, that is add one or more objecttypes related to the Main object type originally selected in the CNA base window

Add MOs to or remove MOs from a CNA Table window using conventional copy or cut

- and - paste techniques.

Copy, Cut, and Paste may be used on the Main object type tab; on the Related object

type tabs, only Copy is available. The objects copied may be pasted into another CNATable window where the object in question is the Main object type

Parameters for related MO types can be displayed in the CNA Table window. Each

worksheet in CNA Table contains parameters for one MO type. The parameters aredisplayed by clicking the tab for the desired MO type

Customize a CNA Table view and save it for future use. (Default and predefined

Table Views cannot be customized.) The user can save an unlimited number of CNATable views for each object type (CNA does not impose any limitations, but theremay be system limitations)

Select any existing Table viewNote:

CNA Table includes a default CNA Table view, which cannot bedeleted, where all parameters for the object type may be viewed

Switch to any of the existing CNA Table views at any time

Change the relative order of the displayed rows and columns

Sort the order of the displayed rows in ascending or descending order using anycolumn as the sorting key

Hide and show parameter columns in order to limit the number of displayedparameters and thus to enhance the readability

Freeze and unfreeze any row or column during the presentation. Freezing means that

the applicable row or column always remains visible, regardless of the scrolling

Use CNA Table to display and modify all or part of the parameters used by aspecified set of MOs

Show the relation between objects by choosing the Select Related Objects menuitem in the background menu





Change several user selectable MO parameters simultaneously

Reset or restore editable MO parameter values. Resetting an MO parameter valuereturns the value to the last applied value. Restoring an MO parameter value sets thevalue equal to the parameter value in the valid area

Set and change the desired print properties

Select the object parameters which are to be printed. The printout may be assignedcustomized headers and footers for easy identification

Use the CNA Table function to export MO parameter values in SYLK (Symbolic LinkFormat) or ASCII (American Standard Code for Information Interchange) format


A CNA Table is always in one of the following three modes:

View Mode, which is entered if the current area is not a planned area which islocked by the current user

Edit Mode, which is entered if the current area is a planned area locked by the

current user

Freeze Mode, which is entered if the area in CNA Table is not the same area asthe current area in the CNA base window. That is, when loading another areain the CNA base window

Indicates the parameters which cannot be changed

Indicates the parameters which have been changed

Automatically validates changes when the user leaves a changed parameter cell

Synchronizes CNA Table with the other parts of the CNA user interface regarding MOparameter and status changes

Provides context sensitive on screen Help information

3.13.3 Graphical Cell Configuration

The GCC is intended to help the user to discover inconsistencies in the cellular network

visually and to navigate more easily among the cells in the planned areas and the validarea.

The map consists of several layers with different geographical information which can beswitched on or off at any time. The cells are displayed as hexagons. The size of theindividual hexagons depends on the geographical distance to the closest cell in the

applicable layer and does not reflect the real coverage.


Select any cell displayed on the map. A selected cell is surrounded by a frame on themap and automatically becomes the current selection in the CNA base window,provided that the CNA has been connected to GCC. The properties of a cell are

directly accessible when it has been selectedNote:

RNCs cannot be displayed on the map

Select any site on the map. A selected site is surrounded by a frame on the map and

automatically becomes the current selection in the CNA base window, provided thatthe CNA has been connected to GCC. The site properties are directly accessible whena site has been selectedNote:





UTRAN cells cannot be displayed on the map

Select several cells displayed on the map. Selected cells are surrounded by a frameon the map and automatically become the current selection in the CNA basewindow, provided that CNA has been connected to GCCNote: internal cells and foreign cells cannot be displayed at the same time in

the CNA base window. If both internal cells and foreign cells have been

selected on the map, internal cells are only displayed in the CNA basewindow, and the internal cells selected on the map are highlighted.

Select several sites displayed on the map. Selected sites are surrounded by a frame

on the map and automatically become the current selection in the CNA basewindow, provided that CNA has been connected to GCC and that the sites selectedbelong to the same BSC. (sites cannot be displayed on area level.)Note: cells and sites cannot be displayed at the same time in the CNA base

window. If both cells and sites have been selected in the map, cells are

only displayed in the CNA base window, and the cells selected in themap are highlighted

Switch the map layers on and off

Find and select cells or sites with incomplete data which makes them impossible to be

displayed on the map

Select the parameters which control the coloring of the cell or the cells

Assign colors to existing parameter values, individually for each radio parameter andnetwork element. These parameters may for example be LAC, CO, RO, BCCHNO,NCC, BCC, or BSIC

Note: Some parameters are not valid for foreign cells and internal cells of versionOTHER. The selected parameters are displayed one at a time

Specify the default parameter color map during the first map presentation. Severalvalues may share the same color. The selected color settings are automatically saved

Modify the default colors representing the different values of the parameters, forexample LAC, CO, RO, BCCHNO, NCC, BCC, or BSIC, at any time

Switch a scale bar displaying the current map scale on and off

Save GCC views with customized names. This makes it possible to return to apreviously selected set of map layers, map location and scale

Open multiple map views

Pan and zoom the current map view

Find an internal cell or a foreign cell whose name matches a user defined string. The

cells are presented in a list where the user can select a name and find the selectedcell

GCC can:

Display sites and internal cells in separate map layers. GCC may also display foreign

cells, neighboring cells, and overlaid subcells

Start with the data from the valid area or from the area which is currently loaded in

CNA, if CNA is connected to GCC

In GNIP It is possible for the user to:





Start CNA from the GCC application menu

Display cells in separate layers, using information provided by GCC

Display cells in different default layers based on system type and hierarchical data orin user defined layers using information provided by GCC

Display hexagonal cell shapes with symbolic radii

Present all sites as symbols positioned according to their geographical location. Thesize of the site symbol depends on the map scale. sites are individual graphic objectsin a separate map layer which can be switched on or off

Refresh (reload) GCC data on the GNIP map, that is, update the GNIP map with thevalid area and the changes made in a planned area, provided that CNA has beenconnected to GCC

Display neighbor relation in three different ways:

* The neighboring cells to a selected cell.

* The cells to which a selected cell is a neighbor.

* The two-way neighbor relations for a selected cell.

These cells are indicated by filling the cell shapes with a special pattern and by givingthe cells the same indication as the selected cell

Display the identity of the MO on which the cursor is resting for more than apredefined time

Display the cells, with colors according to the color parameter, on top of a map withgeographical information. The cells and the map are displayed simultaneously

Position the MOs to display in the valid area and in all planned areas on the mapaccording to the geographical location of their sites

Cell related data can be managed in the following NEs in a GRAN radio network:

This includes support of Ericsson MSCs and BSCs which exist in a multi- vendor network.CNA supports both BSCs and BSC/TRCs, but considers both to be BSCs.

The following limitations apply:

CNA does not support loading of the different maps used by GNIP from externalmedia into the OSS-RC

Table 2 Supported NE s

NE TypeMSC

BSC or BSC/TRC





Copying of parameters between objects is only possible for objects of the same

revision

GNIP cannot draw two omni cells located at the same site in a common GCC layer
