that sit on top of their networks and enable them to maintain optimal

service quality for each individual subscriber - no matter how loaded the

networks become. Quality of Service is becoming an increasingly

important differentiator for operators as they look to launch and enhance

advanced services, and as data traffic on wireless networks continues to

increase due to the launch of new services such as multimedia messagingservice (MMS), gaming and business enterprise applications.

The IVS software is the first of its kind to enable wireless operators to

tap into the link between the radio interface and the Packet Data Switch

Node (PDSN). This dataset is a particularly rich source of user traffic

and signaling, allowing operators to examine throughput and quality

statistics that are not available from call and packet detail records, peg

counters, and other standard network data. With these new metrics,

operators can solve more detailed network performance problems by

drilling further into the lower-level signaling or protocol data. In

addition, operators can synchronize core network measurements with

over-the-air drive tests and call trace measurements to gain an end-to-endview of network performance.

Support for Fragmented IP

IP protocol performs fragmentation by breaking up a datagram into

smaller individual pieces called fragments. Each fragment has its own IP

header, which is a replica of the original datagram header. Thus each

fragment has the same identification, protocol, source IP address, and

destination IP address as the original IP packet. To distinguish fragments

and allow correct reassembly, the offset field of each fragment contains

the distance, measured in 8-byte units, between the beginning of the

original datagram and the beginning of that particular fragment. The first

fragment by definition has its offset set to 0, the second fragment has as

its offset value the payload size of the first fragment, and so on. All of

the fragments except the last have the more fragments bit set so that the

end host waits to receive all of the fragments before reassembling them

into the original IP datagram.

IVS automatically recognizes fragmented IP packets and correctly

reassembles the payload so that the underlying content can be decoded

and used for advanced analysis and troubleshooting purposes.

Support for MIP

Mobile IP allows terminals to roam freely to other networks while still

maintaining the same IP address. Mobile IP consists of three

components: mobile node, home agent and a foreign agent, latter two

being basically routers with some special functionality. A home agent

allows mobile nodes to roam to other networks. A foreign agent allows

mobile nodes from other networks to visit to the network.

The following MIP Measurements are supported:

Registration Information

Session Lifetime

Home and Foreign Agents

User Name (NAI)

Authenticator

And more

Support for RTP

RTP (Rapid Transport Protocol) is a connection-oriented, full-duplex

protocol designed to transport data in high-speed networks. RTP

provides reliability, in-order delivery, segmentation and reassembly, and

adaptive rate-based flow/congestion control. Because RTP provides these

functions on an end-to-end basis, it eliminates the need for these

functions on the link level along the path of a connection. Instant

Messaging is an example of an application that uses RTP.

The following RTP Measurements are available in IVS:

RTP Header Information

RTP Payload Information

RTP Sequence

RTP Timestamp

RTP Server Delay

RTP Lost Packets

RTP Phantom Packets

Note Average, Instantaneous, Minimum, andMaximum Throughput are available for all

measurements.

Support for PAP

The Password Authentication Protocol (PAP) provides a simple method

for the peer to establish its identity using a 2-way handshake. This is

done only upon initial link establishment.

After the Link Establishment phase is complete, an Id/Password pair is

repeatedly sent by the peer to the authenticator until authentication is

acknowledged or the connection is terminated.

The following PAP measurements are available in IVS:

Peer ID

Password

Support for CHAP

The Challenge-Handshake Authentication Protocol (CHAP) is used to

periodically verify the identity of the peer using a 3-way handshake. This


18/36

Page 18

is done upon initial link establishment, and MAY be repeated anytime

after the link has been established.

The following CHAP measurements are available in IVS:

Challenge Value Challenge Name

Result

Support for WAP

The Wireless Access Protocol is a free, unlicensed protocol for wireless

communications that makes it possible to create advanced

telecommunications services and to access Internet pages from a mobile

telephone. Wireless application protocol is a de facto industry standard

supported by a large number of suppliers.

The following WAP measurements are available in IVS:

Throughput (Uplink and Downlink)

PDU Type

Version

Payload and Payload Length

Transaction Information

And more

Support for FTP

The File Transfer Protocol (FTP) provides the basic elements of file

sharing between hosts. FTP uses TCP to create a virtual connection for

control information and then creates a separate TCP connection for data

transfers. The control connection uses an image of the TELNET protocol

to exchange commands and messages between hosts.

Support for HTTP

The Hypertext Transfer Protocol (HTTP) is an application-level protocol

with the lightness and speed necessary for distributed, collaborative,

hypermedia information systems. Messages are passed in a formatsimilar to that used by Internet Mail and the Multipurpose Internet Mail

Extensions (MIME).

Support for RADIUS

The Remote Authentication Dial-In User Service (RADIUS) Protocol is

used for authenticating user connections and for tracking connection

time.

Improved Performance

A10/A11 Interface logs can be too large to fully load in to IVS. By

default, IVS partially loads files of this type, and calculates the results of

load time analyses as it scans through them. Using this MinimalLoad method, IVS is able to load extremely large amounts of data while

using very little machine resource.

ALoad Time queryis any normal query that has been specified to be a

Load Time query. All Load Time queries existing in a work-session will

run whenever a data file is next loaded.

Load Modecontrols the type and detail of data loaded into Analyzer

when you load a data file. The two possible modes areFullandMinimal.

In Full Load, all data attributes are loaded intoAnalyzer from the specified data file. This can take a

considerable time and should only be used whencreating or editing Load Time queries.

In Minimal Load, only user-selected Scenarios orLoad Time queries are loaded into Analyzer.

Scenariosare collections of Load Time queries that can be applied to

PCM Link data, as it is loaded into Analyzer. You select the Scenarios

you need, depending on the tasks you want to perform. However, the

more Scenarios that are selected, the longer the data takes to load, soonly the basic analysis sets are selected by default.

Note Note that only Actix can create and editScenarios.

Automated Correlation of Drive Test and A10/A11

Measurements

The Actix synchronization wizard allows you to synchronize

measurements made at the A10/A11 interface with those made during a

drive test. Drive test measurements can be either CDMA1x handset orCDMA1x EVDO handset measurements.

Once synchronized you will be able to trace performance information

across the entire network, from the air interface to the core network,

giving you the ability to identify core network, subscriber, handset and

Internet destination-specific problems.

Here is a description of the steps of the wizard.

Introduction

This page provides an introduction to the wizard. There is anoption to browse for files to load into Analyzer before

continuing.


23/36

Page 23

Browse for files

This page allows the user to load files into Analyzer. This can be

done by clicking the Browse button. This process can be

repeated as many times as needed until all the required files have

been loaded.

Select Measurements

This page displays the data that has been loaded into the

workspace and groups it in a table. The table has 4 columns. The

first is a check box, second is the drive test data stream name,


24/36

Page 24

third is the phone number or ESN for the drive test data stream

and the fourth is a list of all A11 IMSIs aggregated from all

protocol data in the workspace.

If no valid data is present for either drive test or

A10/A11 Interface the Next button on this page is

disabled. You need to either select Back to go to the

previous page and select files to load or Cancel to exit

the Wizard.

When Next is selected it takes a few seconds to advance to the

next step. The wizard is processing data here, for each selected

IMSI it creates a sub-stream in all the A10/A11 interface files in

the workspace.

Sub-stream for selectedIMSI.


25/36

Page 25

Select Synchronization Method

This page provides the different methods that can be used to

determine the time-offset between the drive test and A11 datastream. The user has the option to select one of the following:

oParameter Correlation using DT Call Durationand A11 Active Connection Time.

oParameter Correlation using IP Parameters fromDrive test and A11 streams.

oParameter Correlation using throughput valuesfrom Drive test and R-P Interface.

The second option will only work for log files capable

of logging raw IP Packet data.

When Next is selected it takes a few seconds to advance to the

next step. The wizard is calculating the time offset between the

drive test and A11 streams using the method selected by the user.

Time Offset Verification


26/36

Page 26

Based on the synchronization method selected in the previous

step the time offset calculated is presented to the user. This is

formatted as HH:MM:SS.ms. The user has the option to override

this value and enter the desired time offset.

The other option provided on this page is to use the same timeoffset for all the streams selected for synchronization. If this

option is selected the user does not go through the time offset

calculation and verification method for each stream. Instead all

the selected streams are synchronized at once.

The time offset is always calculated using the drive test

stream as the reference point. In the above case the

negative value indicates the A11 stream time stamps

need to be offset back by that value for the streams to

be synchronized.

When Next is selected it takes a few seconds to advance to thenext step. The wizard is creating the Super stream in this step

using the time offset provided.

Final Page

This page appears when Super streams have been created for all

the selected streams.

A table shows the list of Super streams created with the

corresponding Phone number and the A11 IMSI.


27/36

Page 27

The generated super stream contains all radio link and R-P Interface

measurements. The user can overlay KPIs from different interfaces for

quickly troubleshooting problems across the entire network.

Known Issues:

In the current release only one super stream can becreated for a given drive-test stream and IMSI pair.

A-Platform Improvements

Improved Event View

The IVS event detection engine is used to identify key network events in

cdma2000 1X networks. This is accomplished by monitoring the A10,

A11, and IP messaging. Using this messaging, the handsets state can be

tracked as it moves between various network states.

The A-Platforms Event Diagram Viewer can be used to visualize these

key events and the handsets progression through the network. Thecurrent state of the handset and its transition between states is

automatically identified each time a data point is selected in any of the

A-Platform views.

Improved Table View

The performance of the table has been greatly improved so that data is

available almost instantaneously for viewing and analysis.


29/36

Page 29

Improved Chart View

The following improvements have been made to the Chart View:

Improved Point Selection - Selecting a point in the

chart is now more precise. You can now only selectvalid points. A previous bug allowing the user to select

phantom points has been fixed.

Improved Stability - Chart properties that could lead toinstability have been disabled.

Note: The correct way to create a line chart is by enabling the border

line for a data series:

Click chart Properties button.

Select the top level Series tab.

Click the line border button.

Select the Visible checkbox.

Improved Message View

The protocol stack browser allows the user to more quickly browse

through messages by examining the header only. Once a message of

interest is identified, the details for the message can be examined.

Messaging for various protocols (when multiple protocols are available)

are formatted into separate columns.


30/36

Page 30

The following improvements have been made to the protocol stack

browser in this version:

Only displays rows with data - Rows without any dataare no longer displayed by default. If you want to see

every message, press the all rows button.

Retains message position - The protocol stack browser

stores the position in the current message that you areviewing so that when you select other messages, the

same position in the message is displayed.

Finding message text - The protocol stack browser cannow be used to search for message text in the same

way as the Message Browser.

Improved Synchronization between Views

The Map, Chart and Table are binned views meaning they display binned

data. The user can select a bin by selecting a point or row in these views.

The Message Browser, Protocol Stack Browser and State Forms aremessage based views. They display data taken directly from the

messages in the file.

Often data from many messages contributes to the value assigned to a

binned. This can make synchronization from binned to message views

more complicated. To illustrate, when the user selects a binned data point


31/36

Page 31

(in the Chart for example), which corresponding message should be

displayed in the Message Browser?

Previously, Actix solutions have always shown the message closest to

the middle of the selected bin. In this way often the message displayed

has nothing to do with the data selected in the binned view. For example,the user might select signal level but be shown a system information

message, simply because that was the message nearest to the middle of

the bin.

The algorithm used for synchronizing data views has been improved to

show a more useful message when possible. Now, if possible, the

message-based views will sync to a message within the bin containing

the selected attribute.

If there is no message with that attribute a message in the middle of the

bin will be selected, as before.

Improved Ease of Use

Search for an Attribute in the Workspace

This new feature provides assistance to users searching for an attribute inthe Workspace Explorer tree-view.

It is opened by the menu by selecting Tools, Find Attribute. It can also be

opened by the hotkeys Ctrl + Shift + F.

Once opened, a search panel is added to the Workspace Explorer tree-

view pane. Users may enter search criteria about the required attributes

into this panel.

Find What: Enter some text which is part of therequired attribute name.

Stream: Select which stream of data should be searched. is set by default.

Settings:

o Whole Word: Check this to search only forattributes where the search text exactly matches

the whole attribute name. Otherwise, search for

attributes where the search text is contained

within the attribute name.

o Case Sensitive: Check this to search only forattributes where the case of the search string

exactly matches the case of the attribute.


32/36

Page 32

Direction: When down is selected, only search forattributes further down in the attribute tree from the

currently selected attribute. When up is selected, only

search for attributes further up in the attribute tree from

the currently selected attribute.

Find Next: Based on the current search criteria, find thenext matching attribute. This attribute is highlighted in

the All tab at the bottom of the Workspace Explorer.

Find All: Based on the current search criteria, find allmatching attributes in the tree-view. The matching
