1 Introduction

1.1 What is Compass Wireless

Compass Wireless is a post analysis tool that processes and presents result based on capturedtraffic files from a range of Anritsu and major competitive protocol analyzers and probes. CompassWireless fits into all departments related to trouble shooting and optimizing of 2G, 2.5G, 2.75G, 3Gand 3.5G networks.

Compass Wireless is the continuation of the success and experience of Compass GSM, CompassGPRS and Compass UMTS each dedicated to analyzing captured traffic files related to GSM,(E)GPRS and UMTS within GERAN and UTRAN domains. Compass Wireless combines more than600 statistical results and features of Compass GSM, Compass GPRS and Compass UMTS andbrings this to a new level of power and performance utilizing a state of the art platform.

Compass Wireless is based on the third generation platform of Compass using a completely newstate-of-the-art Graphic User Interface and database framework. This ensures full scalability and

usability, making Compass Wireless a future-proof solution.

1.2 Classic key Compass features

Key functionality includes KPIs, overall statistics and correlation of A-bis and A/Gb-interfaceprocedures with full decoding. From the network perspective to individual subscriber tracesCompass Wireless gives the answer. Calls are correlated across interfaces providing not just thestatistics on dropped calls but also the reason why. Compass Wireless statistics range from simplemessage counting to correlated procedure counting and analysis of user plane. Compass Wirelessmay be used to quickly find problems related to customer complaints or for optimizing the radionetwork.

Reconstructs all calls in the network by correlating A-bis and A-interface proceduresproviding not just the statistics of dropped calls but also the root causes

Drill down from overall KPI via correlated procedures to individual messages

Analysis based on actual subscriber behaviour rather than limited to drive tests

Full decoding of signalling plane protocol stacks

2 Getting Started

2.1 Welcome to Compass Wireless

The very first time Compass Wireless is started a Welcome page is presented. From the Welcome

page information such as general help, feature help, this document and Anritsu web site may beaccessed. As for most other views in Compass Wireless the Welcome page may be detached,docked, be a fast view or closed. Explore these features by moving the Welcome page around oruse the pop-up menu options available when using a right mouse-click on the tab. When you haveexamined the Welcome page then close it in order to go to the workbench and get started withCompass Wireless.

The Welcome page may be displayed any-time by accessing it from the Help menu. The Helpmenu also contains the Help Contents that is the access to general help, feature help and protocolhelp. Use the online help to get detailed information about a particular result view or general help

on how to operate Compass Wireless.

2.2 Workbench and perspectives

The Workbench is the area containing the perspectives Compassand Compass Server. TheCompass Serverperspective is used for handling workspaces such as creating, deleting andopening workspaces. The Compassperspective displays the current open workspace if any. Younavigate between the perspectives most easily using the icons in the upper right most tap:

The figure below displays the Compass Server perspective including a list of initializedworkspaces.


6/17

Compass Wireless

The very first time Compass Wireless is started there will be no workspaces and you as a userhave to create one or more workspaces. A Ready workspace is an initialized workspace which isthe container of the processed results for one or optional two captured traffic files. CompassWireless can contain many workspaces limited only by the disc capacity.

Besides from the created workspaces the Compass Serverperspective contains the LicenseInformationtab that can be used to get information of the license in use. Use this tab to get

information, about which features are enabled, the ID of the signed SMA if any, the serial number,the type of license and other related information.

2.3 Workspace and initializing

In order to use a workspace it must first be created and initialized. To create a workspace, use theCreate Workspacebutton in the Workspacestab of the Compass Serverperspective. As part ofcreating a workspace one or two traffic files have to be associated with the workspace andcustomized label identifying the workspace can be given; to continue press the Finishbutton. Oncecreated, the workspace is in state Before Initialization and the Initialize Workspacewizard is

launched.

In the wizard assign a traffic file to a domainsuch as GSM, GPRS or UMTS.

If no specific preferences are needed, suchas customizing the time range or alteringthe default thresholds, then press the Finishbutton to process the traffic file or files,otherwise, press Nextto modify alarmthresholds and other preferences.

Note that the preferences available withinthe wizard are also available fromPreferencesmenu item of the Windowsmenu. The wizard uses these values asdefault values for the initialization of theworkspace. The preferences are then fixedfor that workspace unless the workspace isinitialized again. Changes to thepreferences do not affect a workspace that

has already been initialized.

Traffic demo files containing neutralized subscriber information are available from the demos

folder of the installation folder of Compass Wireless e.g. C:\Program Files\Anritsu\CompassWireless\demos. For information about what each demo file contains look into the AboutCompass section for each domain within the Compass Wireless feature Help.

After the traffic file or files has been processed successfully then the workspace changes state toReady. When a workspace is in the Ready state it can be displayed in the Compassperspective. To open a workspace and display it, either double-click the workspace or chooseDisplay Workspacefrom the pop-up menu using the right mouse button. For detailed informationabout handling workspaces read Working with workspaces in the general online help.


7/17

Note that traffic files are still used by Compass Wireless after a workspace has been initialized.Compass Wireless does not process all details of the traffic file but rather processes enough detailsto display the statistics and indexes the rest. When necessary, Compass Wireless will access thetraffic files and get additional information such as in the case of decoding a signaling message. Thereason of this approach is two fold, first this reduces the size of the workspace and secondly theinitial processing is very fast in comparison to other approaches. When data is accessed from the

traffic file then this is done using indexes and in manner that ensure high performance. The speedin accessing additional data from the traffic file is in the same magnitude as if all the data havebeen in the database.

2.4 Displaying workspace results

When a workspace is opened it is displayed in the Compassperspective. This perspective containsthe Compass Menutab and zero, one or more result views.

The content within the tree list available fromthe Compass Menutab changes accordingly to

what domain (i.e. GSM, GPRS or UMTS) thathas been selected during the initialization ofthe workspace and accordingly to the contentof the traffic file(s).

To display a result view, either double click amenu item in the tree view or choose Run Itemfrom the pop-up menu. Alternatively, thekeyboard arrow and Enter keys can be used.

Compass Wireless contains a lot of results butdepending upon the particular customer usage

only some may be of interest or some may beused excessively and become favorites. InCompass Wireless favorites may be added tothe Favorites list of the Compass Menu bychoosing Add to Favoritesfrom the pop-upmenu when right mouse clicking a menu itemin the tree list.

Some menu branches within the tree list of theCompass Menumay be disabled. There aretwo reasons for this, either the traffic file doesnot contain any such data or the license usedis limited to some features only.

From the File Processing Reportof the Reportsmenu it is possible to see what the traffic filecontains. From the License Informationtab ofthe Compass Serverperspective it is possibleto see which features are enabled.


8/17

Compass Wireless

The File Processing Reportis a good starting point to find out what the processed traffic filescontains in case it is not already known. Every other result in Compass Wireless depends uponwhat has been detected in the traffic file or files.

If the Compass Menuis taking up too much space on the screen then it may be minimized,detached or the Fast Viewoption may be selected. The Fast Viewoption is available from the pop-up menu when right clicking the Compass Menutab. When the Fast Viewoption is chosen theCompass Menuwill automatically minimize itself after e.g. a new result view is launched. To

reopen the Compass Menu, click the Compass Wireless icon in the status bar.

2.5 Working with tables

Results in Compass Wireless are either presented as graphs or tables. From tables it is possible todrill into other views by using the right mouse button on a column value and choosing the

appropriateaction from thepop-up menu.Alternativelydouble click a

drillable columnto start thedefault action, i.e.the first action incase that multipleactions arepossible.Columns aredrillable when the

icon isappearing in thecolumn title asshown in the

Sessionand MSIDcolumns in the

figure to the left. Note that especially within the UMTS domain of Compass Wireless many drillablecolumns have more than one action associated.

In some cases it is possible to drill from the entire table to get other information such as all Abissequence related to a list of A-interface sequences. This too will be available from the pop-upmenu but will not be indicated in the result view.

Note that unlike legacy Compass products drilling into a result view in Compass Wireless launchesa new instance of the selected result view and does not close previous launched windows. Theadvantage of this is that the same result view may be launched containing different data e.g.

results from different cells. The disadvantage is that too many similar views can be confusing. Theproposed solution is not to launch more result views that needed and always close the ones thatare not needed.

Aggregations such as e.g. total and maximum may be available below a table. To unfold anddisplay the defined aggregations click on the arrow next to Aggregationsbelow the table. Someaggregations are predefined and others may be user definable. To create a new aggregation or

changing an existing one, click the icon on the main toolbar to display the Aggregations View.


9/17

Compass Wireless

Alternatively use the Show Viewcommand on the Windows menu to display the various TableConfiguration Views.

Highlighting such as coloring rows and columns may also be applied to tables based onexpressions in order to e.g. highlight certain excessive values. As for the Aggregation View, the

Highlighting Viewis accessible from the main toolbar by clicking the icon.

The Filters Viewmay be used to filter the table to display only certain values. The Sorting Viewmay be used to sort the results in ways different from the ascending or descending way. TheColumns Viewmay be used to hide or change the appearance of columns (update the Columns

Viewby using the refresh icon).

The Aggregations View, the Sorting View, the Filtering Viewand the Highlighting Vieware allbased on columns IDs as defined in the Columns Translations View. Note, that the HighlightingViewand search is based on Jython syntax and is case sensitive where the other views are basedon SQL syntax.

For information on how to use the Aggregations View, Highlighting View, Filtering Viewand theother table configuration views look into the section Working with tables within the general online

help.

Note that if necessary the user defined table configuration may be reset to default from thePreferencesdialog available from the Window menu. Alternatively the table configuration for asingle result view may be merged with default settings if Reset/Merge with Defaultsfrom the popupmenu is available when selecting Show View Menufrom the Window menu.

2.6 Working with graphs

Like tables, graphs are a way to display results of the current open workspace.

In Compass Wireless, graphs aredisplayed using different chartobjects, each having differentcapabilities. Using a combination ofShift or Ctrl key together with holdingdown the left or right mouse buttoncharts may be moved, sizes, rotatedand tilted dependent upon chart typewhen dragging the mouse.

For most charts such as chartscontaining curves with dots and

column bars it is possible to get theexact information of a particular valueby hovering the point of interest. Forall charts it is possible to assign labelsor hide one or more series within thechart. To do the latter use the right

mouse button within the chart area and choose Configure Seriesfrom the pop-up menu.


10/17

Compass Wireless

From the pop-up menu it is also possible to select Exportto export a chart into various formats orto choose Toggle Scroll Barto activate or deactivate horizontal and vertical scrollbars. Scrollbarsmay be useful for navigating the chart when zoom is applied.

For more detailed information about graphs look into Working with charts within the general onlinehelp.

2.7 Message Decoding

From most table based result views it is possible to drill further down to get the Message List. Fromthe Message Listit is possible to drill into one or more messages to display the decoding of theselected message or messages within the Message Decodingresult view.

Within the tree view of MessageDecodingresult view, each node maybe collapsed or expanded or becomethe root node. Use the commandsavailable from the pop-up menu whenright clicking within the MessageDecodingresult view.

In order to show one or moremessages at a time, select themessages within the Message Listand choose Show Message Decodingfrom the column pop-up menuavailable from the Msg column.

For more detailed information about the Message Decodingview look into Working with messagetrees within the general online help.

2.8 Navigating result views

Compass Wireless offers many ways to size, move, detach and arrange result views. Results maybe arranged below or above each other or left to or right to other result views or they may remain inthe current window stack, what is possible depends upon the context. On easy way to expand aresult view is to double-click its tab, when done it will size itself to the size of the workbench, to setit back double-click the tab again.

Note, in Compass Wireless the platform term Editor is used as a synonym for a result view andany other view that can be launched from Compass Menu. An example of an Editor or result viewis the File Processing Reportavailable from the Reportsmenu node within the tree list of CompassMenu.

A result view may have one or more panes. This is used when the result view displays two resultssuch as two graphs or when a result view has a filtering pane. The panes may be arrangedvertically or horizontally when using the pane icons (see description in the table on the following


11/17

Compass Wireless

11

page). Panes may also be sized by dragging the grey line that separates most panes within a resultview. Another example using panes is the list of workspaces and the selected workspaceinformation pane as shown in the Workspacestab of the Compass Serverperspective.

Icon navigation Description

Arranges panes horizontally. Available only for results views with panes.

Arranges panes vertically. Available only for results views with panes.Toggles pane maximization within a result view.

A window stack is one or more result views which are accessible from taps placed next to eachother in a tab group and where only the result view from the current selected tab is visible. This isthe default behavior but in some cases it might be useful to display result views (Editors) in a waythat makes two or more results view visible at the same time. To do so, a result view may bemoved onto a new stack using the commands available from the Resultmenu or merely draggingthe result view outside the areas covered by the stacks. New result views that are launched willappear in the current active stack. Results view may be closed by using the close (X) icon in thetab or choosing the various close options from the pop-up menu when right-mouse clicking the tab.

In the figure below there are two stacks, one contains a tab group of three result views and theother stack contains a tab group of two results views. The CELL: Distribution of C/Iresult view hastwo panes which are arranged vertically and the Paging statistics per Paging Groupresult view hasone pane only. A result view is selected in the stack containing the two result views and hence thisbecomes the active stack.

Compass Wireless offers many ways to arrange result views and perhaps this may occasionally betoo much. In such a situation use the close options available from the Fileand Resultsmenus toquickly close all views or stack all results views onto a single stack. If detachable windows such asthe Compass Menuor the Table Configurationviews have been arranged in a way that isundesirable, then choose Reset Perspectivefrom the Window menu to return to the default

settings. For a full list and detailed description of all commands available within Compass Wirelesslook into the Reference section within the general online help.

2.9 Menu bar

Compass Wireless contains a dynamic menu bar, meaning that the menus and menu-itemschanges accordingly to what is possible in the current context. A detailed description of theindividual menu items are given in the Reference section of the general online help.

Menu Description

File Closes Compass Wireless or one or more result views.

Result

Offers the possibility to close current or all stacks and to create a new stackfor the current result view and arrange it either to the left, right, below orabove the current stack.

ExternalTools

Contains tools that are to be used prior to initializing a workspace. The menuoffers tools for merging two GSM traffic files and to decipher Gb encryptedtraffic.

Window

The Window menu offers ways to handle perspectives and result views(Editors). From this menu it is also possible to access the Preference dialogthat is used for setting mainly initialization parameters.

HelpOffers access to online help for GSM & GPRS features, general features andprotocols.

2.10 Online help system

Online help is available from the Help menu of Compass Wireless menu bar. Context sensitive helpor dynamic help is available by pressing the F1 key. Using the F1 key gives links to related topicsbased on the general help. For help on how to interpret the result views them selves click on the

help icon in the upper right corner of the result view to go directly to the help page for the resultview. Alternatively the feature help may be accessed from the Help menu where Table of Contentsof the GSM, GPRS and UMTS feature help matches the structure of the Compass Menu. CompassProtocol Help is online help on the main standardized protocol layers supported by CompassWireless. This is useful to e.g. find help for a particular information element of a particular messagetype.

Within the online help system it is possible to add bookmarks, to search in all help available or tolimit the search scope to one or more main books. The search option allows you to use AND, ORand NOT expressions together with wildcards.

For more detailed information about the potential of the online help system look into sectionReference within the general help.

3 Miscellaneous

3.1 Result views

A result view is any view that display a result based on the initialized workspace. In other words it

displays the content of the processed traffic file(s) as statistical results in tables and graphs. Thestarting point of the result views is the Compass Menuas presented in section 2.4. From hereoverall results can be accessed and from these result views other result views may be drilled into.A good starting point is to look into the File Processing Reportand for the GSM domain into theWarnings and Alarmsresult both available from the Reportsmenu. The File Processing Reportwilldisplay overall information about the traffic file such as the duration, number of links and detectedprotocols. Several things can go wrong when capturing traffic from a network, the most commonmistake is to forget to include all links. Look into the feature help for information on how to interpretthe results and for information about various warning message stated. Results available for theGSM domain are placed in the GSM node of the Compass Menu; likewise the results for the GPRSdomain are placed in the GPRS node and UMTS domain results in the UMTS node of theCompass Menu.

3.2 Common settings

Some but not all results views depends upon settings within the Administrationmenu and within thePreferencesdialog available from the Windowsmenu of the menu bar in Compass Wireless. Thesesettings are common not just to all result views within a domain, but also across domains and insome cases across workspaces.

From the Administrationmenu, it is possible to:

1. Assign new names or change existing network namesbased on the MCC MNC digits of IMSI.

2. To update the mobile type based on the TAC field ofIMEI.

3. To assign names to identified cells.

4. To create and name groups of cells.

5. To define and assign names to dual band cells.

6. To change successful and fail criteria.

7. To assign RNC and core network node names.

8. To modify successful and fail criteria for UMTSprocedures and activities.

Look into the feature help for help on these settings. Sample files for importing are available in theinstallation path under:..\demos\import files.

From the Windowmenu of Compass Wireless menu bar it is possible to access the Preferencesdialog. From the Preferencesdialog it is possible to change default settings used in graphs and inresults views such as the network code for the network under investigation. Other settings apply tothe initialization phase of the workspace e.g. time offset and alarm thresholds. From thePreferencesdialog it is also possible to reset the user defined table configurations and to setpreferences such as default export folder.

3.3 External tools

Two external tools are available from the External Toolsmenu of Compass Wireless menu bar.These tools are the Gb deciphering tool and the File Merging tool. The Gb deciphering tool is ableto decipher Gb traffic off-line. Another approach would be to have the capturing device doing anonline deciphering as it is possible with Anritsu MasterClaw and NetClaw products.

3.3.1 Gb deciphering tool

To decipher encrypted Gb messages using the tool two things has to be available: First theencrypted traffic file and secondly a file with the necessary deciphering keys as passed via the Grinterface. If the keys are contained within the traffic file then make a copy of it and name itsomething else because the deciphering tool requires that the key file and the traffic files are twoseparate files.

In order to be able to decipher with success, the traffic file and keys most span a time window thatallows deciphering to take place. In other words the keys that are used for deciphering may havebeen exchanged between the HLR and the SGSN many hours or even days in advance and maybe reused by the SGSN/PCU for the messages captured in this traffic file. The decipheringpercentage is much affected by this fact. Likewise great care should be taken in recording allnecessary Gb links in order to track updates of P-TMSI. In a GPRS network, ciphering is donebetween the mobile station, through the GPRS access network to the SGSN. Ciphering takes placefrom when the user attaches to the GPRS network. On attach the SGSN retrieves the subscriberinformation and other information from the home location register (HLR) and based on the keyspassed to the MS and SGSN starts ciphering.

3.3.2 File merging tool

The File Merger is a tool that is able to merge two captured traffic files containing GSM traffic intoone file. The output file is of file format ULF which is an internal Compass specific format with farless overhead than most file formats. This also means that the size of the combined file will

normally be considerably smaller than the sum of the two original files sizes.

The files used in merging should have some commonality. It is not advisable to merge two filescaptured at completely different times or completely different networks. The tool allows merging oftwo files produced by two data capturing devices at the same time such as:

1. A traffic file with captured A-interface traffic from one BSS and a traffic with captured A-interface traffic from an adjacent BSS or

2. A traffic file with captured A-interface traffic from one BSS and a traffic file with capturedAbis interface traffic of one or several cells within the BSS.

The File Merger does not rely only on the timestamp inserted for each message in the files,because they often are not perfectly synchronized. In order to properly merge files, asynchronization algorithm is necessary. To synchronize the two files, the following principles havebeen implemented:

1. Synchronization between two A-interfaces traffic files:

The File Merger searches for at least two calls that make handovers between the two adjacentBSSs. The time adjustment needed on timestamps of records in the second file is calculated insuch a way that all messages part of the handover procedure match.


15/17

Compass Wireless

15

2. Synchronization between A and Abis interfaces

The File Merger searches for at least two calls being established with DTAP messages thatcan be seen on both interfaces. The time adjustment needed on timestamps of records in thesecond file is calculated in such a way that all messages part of the call establishmentprocedure match.

Synchronization time is generally very short if recordings have started approximately at the sametime. A long synchronization time indicates an important difference between the beginning of filesor, at the worst case, no possible synchronization. If synchronization cannot be established, thetime difference is defaulted to zero and files are merged using the timestamp.

The File Merger compensates for the fact that the source IDs may be the same in both files withoutactually being the same sources. Whenever the tool detects a collision of source ID in the two files,the source IDs of the second file is modified to retain uniqueness.

When time difference between files is established, the output file is created. Records are read fromboth files. Timestamp of records in first file is left unchanged while timestamp of records in second

file is corrected by the time difference. Records are written sequentially in ascending order ofresulting timestamp.

At the end a text file named AmiMerge.txt is generated to provide the user with the followinginformation:

names of the files that have been merged

timestamp of first and last messages read from each file

timestamp of the first and last messages written from the second file

time difference between files

mapping of the input data sources to logical output data sources.

3.4 FAQ list

Q1: I have organized my window layout in a silly way and now I do not know how to return to theoriginal layout.

A1: Choose Reset Perspectivefrom Window menu to return to the default window layout.

For questions and answers on installation issues look into the Installation Guide on the installationmedia.

Q2: How can I share my aggregations and highlight settings with my colleague?

A2: The settings are by default stored in the following folder: C:\Program Files\Anritsu\CompassWireless\client\workspace\.metadata\.plugins\com.nettest.compass.core.ui. To share it with yourcolleague, copy the files of this folder to the same folder of the target PC.
