MD8430A DEMO CONFIGURATION
Demo Procedure 1 - Full stack data testing
The demonstration scenario will show the following: Full attach and default bearer setup under fading conditions Attach will include:
• TX diversity signalling • Full Security
– Authentication – NAS ciphering and Integrity using SNOW 3G– RRC/AS ciphering and Integrity using SNOW 3G
• MIMO data channel using fading to achieve full throughput Full Category 3 100/50Mbps IP data using TCP, UDP or streaming Interactive script design to show run time user interaction
• User can change resource allocation, number of RB, MCS for UL and DL
• All RF measurements can be made using MS269xA on UL and DL• User can change data rates by corrupting DL CRC or sending user
configurable PHICH pattern UE detach from network
Demo Procedure 1 - Full stack data testing
Clicking user event buttons changes MAC configurations
Messages Sequence and decodes can be viewed on runtime MSC
Demo Procedure 1 - Full stack data testing
Quick and easy L3 message parameterisation for sending RRC/NAS messages
Automatic generation of security encryption and integrity
Demo Procedure 1 - Full stack data testing
Quick and easy L3 message parameterisation for receiving RRC or NAS messages to create message constraints
Automatic checking of NAS and AS security
Message mismatch node for checking of message constraints
Integrated message timeout When triggered procedure willExit on TO node
Demo Procedure 1 - Full stack data testing
Fading is demonstrated on the MIMO channel With fading off the UE achieves 50% data rate as there is no
multipath to achieve MIMO independent channels RF Spectrum shows fading as power variations with time and
frequency Constellation of DL also shows phase and amplitude changes
Power Vs RB viewShows bitmapAllocation
Constellation showsamplitude and phasevariations caused by fading
Demo Procedure 1 - Full stack data testing
Trace viewer for detailed message analysis in run time
Demo Procedure 1 - Full stack data testing
Post process of binary log for detailed DL and UL analysis
Analysis contains very detailecd information on a TTI/TTI basis
Demo Procedure 1 - Full stack data testing
Using the Measurement capability of the RTD we can view the effects of the RTD user events on L1 and L2This will also be viewed on the Analyser and IP data rate
Demo Procedure 2 – RLC AM L2 testing
RTD has a comprehensive L2 testing libraryUsing the L2 procedures and codec users can exercise every aspect of MAC, RLC and PDCPThe demo shows how to test various aspects of RLC Acknowledged mode using 3GPP defined UE loopback modeThis allows quick and easy creation of 36.523 variation without the need for TTCN3 L2 procedures grouped into easily reusable compoundproceduresUsing a combination of scheduling and L2we can create complex tests quickly and easilyPDU generator makes sequence number andheader creation simple

Demo Procedure 2 – RLC AM L2 testing
PDU Generator can be used to provide PDCP or RLC PDUs for easy implementation of L2 tests.
Multiple Stream modes
Demo Procedure 2 – RLC AM L2 testing
Criteria Editor Allows addition of indicator points in test case Indicator points can be used as pass of failure Easy creation of objective testing

Standard protocol analyser for detailed debug
Demo Procedure 3 – L3 Procedure Library
High level L3 compound procedures can be used to build complex multi cell tests in a short timeCompounds are parameterised for easy customisationL3 messages are used to generate control primitives this guarantees alignment between UE and MD8430Roadmap for L3 procedures available on requestMid level L3 procedures will be based around individual messages for even more flexibilityBuilt from and can be combined with low level procedures for full configuration flexibility
Demo Procedure 3 – L3 Procedure Library
Automation of testing
Tests can be sequenced using integrated campaign manager
Automation of testing
RTD has a command line interface for automation as a slave application driven by customer test management softwareRTD has integrated control of UE using AT/MMI commands
Multi-RAT testing
From RTD 4.3.1 there is a low level procedure library for testing IRAT between LTE, UTRAN, GERAN and CDMA2000UTRAN/GERAN LL library uses PTS interface primitives for configuration of MD8480 and L3 messages
