NQDI is SwissQual’s post-processing system. It can be used with the data produced by the QualiPoc and Diversity families for network optimization, service monitoring and benchmarking.

NQDI provides a detailed analysis of the quality of voice, video, and data services using primary RF measurements, network trace events and call control parameters for all radio technologies.

NQDI

Scalable, flexible, detailed processing, investigation and reporting of network survey data..

NQDI correlates information from physical, service, and application layers in time-synchronized views using maps, grids, line graphs, bar graphs, pie charts, tables and hierarchical lists.

CorrelatedNQDI offers extensive payload analysis of voice and video services, with onboard QoS algorithms supporting troubleshooting and optimization the end-to-end services QoS.

Payload TechnologiesNQDI supports all the major mobile radio technologies, including GSM, GPRS, EDGE, WCDMA R99, HSDPA R4, HSUPA R6, HSPA+ R7, CDMA2000, EV-DO, IS-136, iDEN, DVB-H, WiMAX, and LTE.

GUINQDI has a smart adapting GUI which is sensitive to the context of time & date, technology, operator, device type, map polygons, quality thresholds, and events being displayed.

LayersNQDI allows time-correlated physical and protocol diagnosis across numerous layers – RF, L2, L3, TCP/IP, RTSP, UDP,H.245, H.324M, WAP, HTTP, FTP, streaming media player and more.

StorageNQDI stores detailed information in the database instead of aggregated data and raw binary files, allowing more detailed analysis, more flexible filtering and long-term trend analysis.

CentralizedNQDI is designed as a client/server application using Microsoft SQL Server as a data repository and is fully scalable from a standalone laptop solution to large client/server enterprise systems.

AutomatedNQDI has automated analysis of CS and PS calls with failure cause categorization that assists the user in finding the top most quality degrading network problems within just a few seconds.

NQDI

Did you know?

Making complicated systems is hard. Making them easy-to-use is harder still. But SwissQual has taken giant steps in making systems that deliver complex answers very quickly.

We not only give customers the ability to define their own bespoke KPI values, but also calculate them in real-time live, during data acquisition. That means that the KPIs coming directly off the network drives are those the customer likes to see, without waiting for any post-processing.

Smart

Features• Combines high level KPI

summaries with full access to

detailed drilldowns

• Smart adapting GUI is sensitive

to contextual information

• Time synchronization and

correlation of numerous data

layers helps automate fault

categorization

“NQDI goes beyond basic

post processing and allows

us to get into extreme detail,

even looking at voice and

video MOS scores for individual

calls. That’s important when

the delta between being first

or second for quality is just one

dropped call.”

NQDI Specification

TECHNOLOGIES

Extensive technology test support including:GSM, GPRS, EDGE, WCDMA, LTE, CDMA/EVDO, WiMAX, HSxPA, iDEN, IS-136, TDMA, PSTN, ISDN and IP.

SYSTEM ARCHITECTURE

Microsoft® SQL Server® database engine fully scalable from a standalone laptop solution to large client/server enterprise systems with Terminal server. Supported on both 32- and 64-bit Windows® platforms to ensure that the user can find the optimal balance between price and performance. Available with named and floating licensing.

DATA STORAGE

Store detailed information in the database to avoid compromising the flexibility and detailed analysis filtering. Due to the intelligent design of the data files produced by the SwissQual probes the import speed into the NQDI database is extremely fast.

PROTOCOL LAYERS

Full logging and decoding of multiple protocol layers on all technologies:

3GPP and 3GPP2 RF, L2, L3. TCP/IP including PPP, RTSP, WAP, SIP and more.

USER INTERFACE

Context sensitive user interface adopts the presentation automatically to the content and technology, there is no need to change between workspaces or rearrange any windows manually. Drill down and visualization of information from Service and Application layers down to RF in time synchronized views using maps, grids, line graphs, bar graphs, pie charts, tables and hierarchical lists.

DATA SELECTION

Flexible and customizable data selection and filtering capabilities including time & data, network technology, operator, provider, device type, map polygon regions, service quality thresholds, call markers, layer 3 messages and much more. User can save and easily reuse the most used selection parameters from a Favorites list.

AUTOMATED ANALYSIS

Automated analysis of CS and PS Calls with failure causes categorization that assist the user in finding the top most quality degrading network problems, which are detected in the measurement data, within just a few seconds.

SERVICE ANALYSIS

In depth analysis of all mobile network services and protocols:- Voice telephony: CS & VoIP Speech MOS (narrow and

wideband), noise suppression, Echo, RTT, DTMF- Data: Ping, FTP, UDP, HTTP- Browsing: WAP, HTTP IE- Messaging: SMS, MMS, E-mail- Video streaming and media layer analysis: MPEG4, H.263,

H.264- Mobile TV: Video IP portals- 3G Video telephony

SPEECH AND VIDEO QUALITY ANALYSIS

Detailed and accurate analysis of all measurement values captured with SwissQual and ITU voice and video MOS algorithms:- ITU-T and SwissQual POLQA - ITU-T P.862/P.862.1 (PESQ)- SwissQual SQuad intrusive voice (narrow & wideband),

echo, noise suppression and RTT- SwissQual NiNa+ non-intrusive voice- SwissQual VQuad and VMon video and multimedia also

featuring audio-visual synchronization assessment

IP ANALYSIS

Dedicated protocol and IP throughput analysis of Diversity and QualiPoc probes IP trace data including DNS resolver details. Files including PCAP IP trace can automatically be loaded into Wireshark® with NQDI time synchronization.

REPORTING

More than 200 KPIs available for Service QoS and Network performance reporting and trending. The extensive set of Standard Reports includes Voice, Video, Data, Messaging, GSM, WCDMA, CDMA, GPRS/EDGE and HSPA reports. It also possible to embed map plots in the reports.

REPORT GENERATOR

KPI report generator allows users to create their own custom KPI reports that are saved in the database and can be easily shared across your organization. The Excel reports can contain success rate and average pivot tables with PDF, CDF and Pie charts. A trending sort function can group the data into time bins ranging from Hour up to Year.

MAP PLOTTING

More than 500 pre-defined Map plot items in a powerful and fully configurable plot engine which supports MapInfo and Google Earth. Support configurable binning on grid or latitude-longitude precision.

User can save and easily reuse the most used plots from a Favorites list. BTS lists for GSM, UMTS, CDMA and LTE can be loaded. Serving sector line indicates Serving BTS and BTS Coverage function displays BTS sectors coverage for all points like a ‘spider web’. Smart window splitting and map layer offsetting makes the analysis of multiple networks and multiple parameters easy. The map window is time synchronized with the analysis charts and tables.

DATABASE MANAGEMENT

NQDI databases are easily managed with the integrated data management tool, without the need for specific SQL server or database knowledge. NQDI can create and build historical databases to provide the global overview and trending over time.

WEB PLATFORM
