CDMA Network Emulation

AirAccessR

Powerful air interfaceperformance analysis solutionsfor 1X and 1xEV-DO CDMAterminals

CDMA terminal manufacturers facemany test hurdles before they can bringa product to market. Network serviceproviders need to carry out terminalevaluation and compliance testing.The demanding scope of theserequirements requires lab test solutionswith a feature-rich network emulationcapability - not available until now.

In clear contrast to real infrastructureequipment, one box radio test sets, orprogram-driven protocol conformancetest systems, Spirent’s AirAccess CDMANetwork Emulators have the power andflexibility to perform rapid analysis ofCDMA terminal performance as well asbeing scaleable to complete MinimumPerformance, Signaling Conformanceor Location-Based Services tests.

All of the AirAccess systems offer afull-featured, highly configurable, real-time CDMA network with a dynamicstate machine engine. Unlike program-driven protocol conformance test

Analysis

systems, AirAccess systems can runuser-defined test scenarios without anyrequirement for complex programmingor scripting, and with response timesrepresentative of a real network.

The AirAccess family of networkemulators meet the needs of all CDMAtesting requirements:

AirAccess C2K provides multi-cellemulation of a CDMA2000 1X network,including backwards compatibility of2G air interface specifications.

AirAccess 1xPLUS provides a singleintegrated solution for both 1X and1xEV-DO network emulation. Thisenables the testing of 1X-only devices,1xEV-DO-only devices, or Hybrid AccessTerminals (HATs) with one testconfiguration.

AirAccess provides simultaneousmulti-sector, multi-BSC emulation ofcdmaOne, CDMA2000 and 1xEV-DOnetworks with two independent carrierfrequencies, enabling testing of truesoft, hard and inter-generationhandoffs, plus pilot pollution.

AirAccess provides real-time networkemulation using a dynamic statemachine and powerful GUI.

Powerful, easy-to-use GUI softwaregives comprehensive control overcritical network services, parametersand messages, displays real-timemessages and event analyses and logsLayer 2 and Layer 3 messages. Custommessage generation and call flowmodification provide complete controlof the testing environment.

When integrated with Spirent’sTASKIT software, the scope of AirAccess’capabilities and its Instrument API makeit a powerful component of an TIA/EIA-898, TIA/EIA-98 or Location-BasedServices test solution, allowing a widerange of test cases to be automated.

AirAccess CDMA Network Emulator 2

Comprehensive NetworkEmulation — Coverage of entirenetwork from switching centerto mobile terminal antenna

AirAccess provides programmable,bench-top emulation of cdmaOne,CDMA2000 1X and 1xEV-DO radioaccess networks and relevant networkelements. AirAccess delivers aconsistent and repeatable test platformfor verification of signaling andmessaging conformance. This isaccomplished by implementing networkentities required for a CDMA network(AN, MSC, BSCs, BTSs and

Authentication Center), as well as theadditional network entities required toprovide overlay services (IWF, PCF,PDSN, IWF, SMS Server and OTA Server).AirAccess interfaces with the SR5500Wireless Channel Emulator and theTAS5600 Universal InterferenceEmulator to emulate air interfaceimpairments present in a CDMAnetwork.

AirAccess emulates complex CDMA radio access networks

AirAccess’ dynamic state machine andinteractive GUI make generation ofcomplex test scenarios, such ashandoffs, a simple task.■ No need to write complex programs

or scripts■ Real-time emulation with response

times representative of a realnetwork

■ Multi-sector and multi-BSCemulation with two independentcarriers

Industry Standard Testing —AirAccess C2K and TASKIT/C2Kprovide the functionalitynecessary for automatedTIA/EIA-98 and TIA/EIA-898coverage

Critical to the commercial launch of aCDMA terminal is the successfulcompletion of industry standard testsuites. AirAccess C2K couples withpowerful TASKIT/C2K test executivesoftware to provide maximum coverageof TIA/EIA-98 Minimum Performancerequirements and TIA/EIA-898Signalling Conformance tests all in asingle system. TASKIT/C2K automatesall aspects of test execution, datacollection and results reporting.

For TIA/EIA-98 testing, AirAccesscomplements the functionality typically

found in a one-box radio test set byproviding multiple BTS operation andadvanced control of the CDMA protocol.

For TIA/EIA-898 testing, AirAccessprovides the control and flexibilityessential for interoperability testing,including evaluation of overlay servicessuch as OTA, SMS and data. In eithercase, the system integrates the SR5500Wireless Channel Emulator and theTAS5600 Universal InterferenceEmulator to create the required channelmodels and interference.

Real-Time Network State-Machine — AirAccessimplements a fully configurable,interactive CDMA network

The AirAccess application softwareutilizes a high-speed protocolprocessing engine to create a powerfulprotocol state machine. This statemachine allows real-time evaluation ofa CDMA mobile device as if it wasinteracting with actual networkinfrastructure. Unlike testing with a realnetwork, though, the AirAccess statemachine gives the user complete controlover network configuration parameters.Test parameters can be modified in real-time without the need to go off-line tocreate individual test programs.

Key programmable network parametersinclude:

■ Band classes■ Code channels■ Walsh functions for CDMA code

channels■ Radio configurations■ Network elements configured via

settable parameters (parametersettings are reflected in CDMAmessage fields)

■ Re-configuration of the upper-layersignaling flow

■ All overhead message fields on aper BTS basis

■ All forward-link message fields(including reserved fields)

■ Forward-link messages, customizedand transmitted on-demand

Message and Event Analysis —Detailed real-time over-the-airmessage and event logging aidsin troubleshooting

AirAccess features comprehensivereporting and logging of messaging andevents. Entries are reported within theWindows interface in real-time, andsaved to an industry-standard-formatlog file. All test logs can be recalledand analyzed at a later date, and allentries are time-stamped with systemtime for precise traceability.

The Message Analyzer window records:

■ CDMA signaling messages■ RLP control frames■ RLP data frame headers

The Event Analyzer window records:

■ L3 state change (e.g. Conversation-> Idle)

■ Expiration of a timer■ Detection of preamble■ Test results■ Error messages

Real-time message loggingand detailed parsing are apart of AirAccess' powerfultroubleshooting toolbox

Full configuration ofmessage and fieldsprovides maximumstate machineflexibility

Handoff Performance Analysis— Create complex handoffscenarios in the lab usingAirAccess

AirAccess allows multiple configura-tions of BSCs and BTSs to supportcomplex handoff scenarios. AirAccessC2K allows operators to select aconfiguration that provides two BSCs,each with independent selection offrequency and protocol emulation. Inaddition an AirAccess 1xPLUS systemallows two access points (APs) to beconfigured on separate RF carriers. Thisallows independent impairments on1xEV-DO sectors for testing of an accessterminal’s dynamic DRC pointingalgorithm.

AirAccess supports the followinghandoff scenarios:

■ Idle handoffs■ Access handoffs■ Soft handoffs■ Hard handoffs■ Inter-generation handoffs

(cdmaOne — CDMA2000)■ Dormant data handoffs

(cdmaOne/CDMA2000 — 1xEV-DO)

AirAccessarchitectureallows thoroughtesting ofhandoffscenarios

Data is one of the key features drivingthe wireless market to third generationservices. AirAccess implements PacketControl Function (PCF) and Packet DataServing Node (PDSN) functionality tosupport high-speed packet dataservices. An Inter-Working Function(IWF) with AT command interpreter isalso emulated to provide circuit-

capability. These features allow testingof the most current data requirements.

AirAccess provides the following datafunctionality:

■ Supports CSD, HSPD and 1xEV-DO packet data

■ RLP1, RLP2 and RLP3■ Asynchronous data and facsimile

transmission■ RLP, PPP and TCP/UDP

monitoring points■ Functional testing via popular

software applications■ Ethernet data port for connection
