4G Complexity is Daunting
New Technology Equals Churn
• New Devices / Standards - Daily
• High Feature Velocity
• Rapid bug fix releases
This makes an already challenging problem quite frustrating
Test Area:– Formfactors / Design
– FPGA
– Processors
– Display
– Keypad
– Touchscreen
– Camera
– Microphone
– Battery and Charger
– Data Cables (Video, USB)
– Headset
– Headset Bluetooth
– Lamp
– Storage
– Data Card (removable)
• Radio Interface (RF)
physics & controlEn-/Decoding
Throughput
• IR
• Bluetooth
• WiFi
• FM Radio
• GPS
• Additional keys for e.g.
• Loudness
• Camera
• Switch on/off
• Sensors (if applicable)
Hardware and Interfaces Software and Interfaces• Platform Capabilities
– Operating System (S60, Windows Mobile etc)
– Platform SDK
• Security• Audio
• Quality
• Codecs
• Voice recording
• Speech recognition (Voice dialling)
• Video• Quality
• Codecs
• Video recording
• Content and File Management
• DRM
• File Manager
• Data transfer via BT, IR, USB
• Graphics
• Applications without network interaction– Music
– Gaming
– Java
– Phonebook
– Calendar
– Clock / Alarm / Worldclock
– Editor
– Document viewer
– Caculator
– Currency converter
– GPS
– Radio FM
• Applications with network interaction– Mobile TV
– SMS
– MMS
– Download, upload files, pictures, videos
– Interactive gaming
– Calendar synchronisation
– Push to talk
– Web browsing
– WAP
– Call Register (in / out / missed)
– VoIP
– IPv6
• Application Interactions – With and without network interaction)
• Application running from Memory Card• Flight Mode
• Concurrency e.g.– Mobile TV and incoming call– Write SMS and incoming call– Receive SMS/MMS during Call– Receive call while any of the applications is running– Video Conference and MMS– Streaming service and incoming/outgoing call– Upload data and and incoming/outgoing call– ...
Layer 2/3 Protocol Testing (Network Signaling) GSM/GPRS/EDGE UMTS/HSPA LTE (example follows)
• Module Testing
• HW/SW Integration• System Integration
2G/3G Mobility IntraRAT-Handover InterRAT-Handover
Protocol Conformance Testing ( ->GCF)
• Services e.g.– Supported Bearers
• SIP / IMS applications (as VoIP !!)
• MBMS (as Mobile TV)
• Different Qos/QCI (=QoS class Identifier in LTE)– Bearers in parallel– Supplementary services (CLIP/CLIR...)– Location Based Services
• Throughput measurements• Performace Testing• IODT• IOT• Drive / Field tests• Type Approval
Testing Ahead of 4G
• 4G is another order magnitude on top of the existing infrastructure
• Profitability and company viability on the line.
• Unbelievable Technology Churn
• Less ability to test manually
• Script based testing is failing
Will Your 4G be on Time?
Can you take a feature test and get it into regression before you release the product or service?
Can you run a full regression suite on a new service, new device feature, or a device software update in less than a week? In two days?
No? Better hope your competitor can’t
