Handset Profiling Benchmark & select handsets according

to users’ QoE

Typical applications

• Procurement: benchmarking / selection of handsets

• Customer Care: troubleshooting

• Marketing: QoE measurementper application

Pushing voice and data services to the next level

With the growing number of mobile handsetsand multimedia contents launched onto

the market, it is becoming increasinglyimportant for operators to benchmark

each individual terminal and meas-ure its performance.

The Astellia “Handset Profiling”application helps operators:

• Troubleshoot quality threateningproblems due to low performinghandsets,

• Choose the best terminals to trigger enhanced mobile voiceand data service usage.

• Visibility of individual handset performance • Faster handset validation process• Deliver the best Quality of experience (QoE)• First-class customer care• Grea ter negotiation power

Visibility of individual handset performance

The “Handset Profiling” application is based on theAstellia passive monitoring solution. Non intrusive, it pro-vides a clear picture of how voice and data are perceivedfrom real handsets and the subscribers’ perspectivefrom any point of the network.

The solution analyzes and measures handset perform-ance from aggregated voice and packet service statisticsover time and location.

Faster handset validation process

“Handset Profiling” provides your procurement and mar-keting teams with reliable tools to benchmark new hand-sets based on specific criteria such as video streaming orcall efficiency. It helps them choose the most efficientsets for optimized voice and data usage.

This enables a faster handset selection and validationprocess and reduces the need for expensive active test-ing and the emulation of hundreds of handsets.

Delivering the best Quality ofExperience (QoE)

New services such as video streaming, MMS and emailapplications are an important source of revenue for oper-ators. In order to ensure top-quality data services,“Handset Profiling” helps you to test applications andmeasure the quality of experience perceived from ahandset perspective.

Using this Astellia application, your marketing team caneasily follow up the introduction of new services andhandsets and measure their usage. “Handset Profiling”gives you a considerable time-to-market advantage.

First-class customer care

With “Handset Profiling”, customer care teams can rapid-ly diagnose problems and identify whether the rootcause is linked to a badly performing network, mobile ter-minal or application.

This allows you to identify problems before they affectcustomers communicating more proactively, therebyincreasing overall customer satisfaction.

Greater negotiating power

“Handset Profiling” is the ideal tool with which to bench-mark the performance of several handsets. It providesyou with comprehensive and objective reports tostrengthen your negotiating power when dealing withhandset manufacturers, selecting new terminals andreviewing contracts.

Top-down investigation

Using “Handset Profiling”, your operations team can easily:

• Detect QoS degradation resulting from a givenhandset type, the introduction of a new handset variant, hardware or software upgrade,

• Pinpoint poor quality handsets causing problemssuch as call drops, MMS failures, setup failure rates,drop rates and HO 3G-2G efficiency,

• Drill down from the Key Performance Indicatorsdashboard to the list of associated Call Data Recordsand Packet Services Data Record,

• Analyze customer problems through multi-interfacecall trace and protocol decoding.

Automated reporting

“Handset Profiling” provides high-level reporting perhandset based on end user and terminal metrics. Itoffers both preset dashboards and the possibility of cus-tomizing your own.

Reports are generated and distributed automatically in amatter of seconds to the right people within your organi-zation. Your management teams are empowered withobjective data, helping them to speed up their decision-making process.

Handset analysis at local / global network level

Handset distribution within your network

“Handset Profiling” provides handset visibility at a localand global network level and for individual networkdevices. Through a single screen, operations teams getin-depth visibility of the various handsets used on allor part of their network per manufacturer, per type ofhandset, etc.

The solution delivers end-user experience metrics forvoice and data services.

Alarm triggering

Alarms might be defined on the basis of exceedingthresholds or from a combination of conditions such asthe number of calls and their success rate for a specificBSC or RNC for instance .

All alarms can be set on any network element on a daily,weekly or monthly basis. In case of problems occurring onthe network such as an increase in location update failures,“Handset Profiling” is particularly useful for identifying causeslinked to specific types of handsets precisely and quickly.

Multi-dimensional Key PerformanceIndicators (KPIs)

The Astellia “Handset Profiling” application offers advancedout-of-the-box QoS and QoE KPIs calculated according tohandset classification (IMEI and User Agent detection) andbased on real traffic observation.

These metrics provide complete visibility of perceived quality.

Per handset:- Manufacturer - Handset type - TAC- Software version

Per service and APN: - Web browsing- MMS- Email, etc.

Per technology: - GSM- GPRS- UMTS

Per equipment vendor element:- RNC- BSC- MSC

Over time: - Per day, week, month and year

Visibility per service

With “Handset Profiling”, application performance is com-pared across multiple handsets from a single screen.

Operators can view how video streaming, webbrowsing, email access and MMS are performing andmeasure the Quality of Experience (QoE) perceivedfor each individual subscriber and handset.

The Astellia “Handset Profiling” application is the idealtool to increase service usage.

Examples of KPIs:

• Attach failure rate and duration

• Call answer rate

• SMS failure rate

• PDP failure rate (global / per APName)

• Wap portal page download time

• MMS success rate

• FTP download throughput

••Streaming session set up time

Up-to-date handset database

The Astellia “Handset Profiling” application features aglobal database of handset references updated by theGSM Association on a regular basis in order to ensurethat all terminals used on the marketare included.

Pre-requisite

“Handset Profiling” is an optional module for the Astelliaglobal monitoring and troubleshooting solution. It pro-vides high-value handset-focused Key PerformanceIndicators.

“Handset Profiling” is used in conjunction with:

• “Trending & Aggregation” for global network reporting,alarming and analysis,

• “Activity Analysis” for troubleshooting and extensiveinvestigation purposes.
