2PLTS Position Location Test System

PLTS System Architecture PLTS provides a complete turnkey testsetup for evaluation of location-capableCDMA mobile device performance. Itis a highly integrated, automated andaccurately synchronized test systemthat builds on Spirent’s globalleadership in GPS and CDMAenvironment emulation.

The AirAccess C2K CDMA NetworkEmulator provides advanced protocolcontrol, including support for the IS-801-1 Position Determination Servicestandard. Simultaneous multi-sector,multi-BSC emulation enablescomprehensive AFLT and handoffscenario performance testing, and anEV-DO option provides a proven testplatform for 1xEV-DO LBS-capabledevices. An impairments option addsthe SR5500 Wireless Channel Emulatorand the TAS5048 Test ConfigurationUnit instruments. This systemconfiguration allows performance to becharacterized under representative fieldconditions.

The GSS5060 GPS LocationSimulator with SimLOCATE software

provides highly accurate simulationof signals and associated propagationeffects from up to 12 GPS satellites attwo independent locations – one forthe mobile device under test, and onefor a static PDE reference receiver. Anintegral Position Determination Entity(PDE) performs network-basedposition determination, usingalgorithms identical to those deployedin actual network entities.SimLOCATE's Virtual Receiver functionemulates the PDE reference receiverand outputs reference data directly tothe PDE to reduce test time.

Two powerful software programsenable automated, closed-loop devicetesting. The TASKIT/PLTS test executiveconfigures the system, executes thetests, then collects, analyzes anddisplays the test results. The UniversalDiagnostic Monitor (UDM) controlsthe mobile device under test whilesimultaneously monitoring its real-time performance. Use of UDM allowsboth mobile-terminated and mobile-originated calls to be automated.

TASKIT/PLTS Test ExecutiveSoftware

TASKIT/PLTS is an advanced,application-specific test executive thatautomates every aspect of positionlocation test execution, data collection,results reporting and results analysis.Test suites are defined in terms of theparameters required in a particular test,instead of instrument-specific settings,making it simple to correlate parametervalues to industry standard testconditions. TASKIT/PLTS automaticallytranslates the parameters in the teststandards to the appropriate instrumentconfigurations.

TASKIT/PLTS automaticallyconfigures all of the system elementsand coordinates the test executionrequired to evaluate the positionlocation performance of a mobiledevice. TASKIT/PLTS collects and

archives all relevant test conditions andresults in an industry-standardMicrosoft Access database. Integratedreport generation makes it easy toextract and display key performancemetrics from the archived data.

The TASKIT/PLTS test executiveprovides a structured means toautomatically execute a series of testprocedures. Test suites are a collectionof individual tests, each designed toevaluate a particular aspect of themobile device’s performance. One ormore related test suites are organizedinto a test session. Any combinationof tests, test suites and test sessionscan be saved and recalled, allowingtest campaigns to be quickly set up andexecuted.

CDMA Network Topology TASKIT/PLTS automatically converts BTSand mobile device location parametersinto a graphical display, allowing the

5PLTS Position Location Test System

The flexibility of PLTSenables a very wide rangeof field test scenarios tobe created, reducing theneed for expensive fieldtrials.

The impairments option combined withspecific test suites gives PLTS field test-like functionality. PLTS emulatesrepresentative field conditions wherepropagation impairments, such asvarying levels of GPS and CDMA signalblockage, multipath interference andDoppler spreading, may be present.Rural, suburban, urban and highwayenvironments, as well as indoor vs.outdoor operation, can present verydifferent operating conditions tolocation-capable mobile devices.

Spirent’s PLTS enables a largenumber of test parameters to becontrolled. Multiple tests can beautomatically conducted over a verywide range of times, locations andCDMA/GPS environments. Thecontrolled test environment ensures

Field Scenario Test Suites

Standard and Commercial TestSuites

TASKIT/PLTS is a cohesive solution fortesting a mobile device to key industrystandards. With this software, pre-defined test suites can be quicklyloaded and executed at the touch of abutton. Test suites for the MinimumPerformance Tests developed by 3GPP2(IS-916) are included with TASKIT/PLTS.IS-916 is intended to ensure that amobile device’s location can bedetermined in any CDMA wirelesssystem that is compliant with the IS-801-1 Position Determination Servicestandard. The statistical confidencedetermination method in the

specification is automatically appliedby TASKIT/PLTS to determine pass/failcriteria.

Utilizing TASKIT/PLTS test suiteseliminates the need to comb throughtest standards and attempt to map thetest conditions to instrument settings.Industry standard tests are regularlyupdated and Spirent provides thecorresponding software updates. Pre-defined tests can be easily modifiedthrough TASKIT/PLTS’s graphical userinterface to create an unlimited numberof custom test conditions.

With the focus of service providersexpanding into commercial location-based services, it is critical tocharacterize the end-user experienceof those applications. Since the IS-916Minimum Performance Tests have onlybeen designed for Control Plane (IS-801-1) transport mechanisms, PLTSoffers User Plane implementations ofthese tests as part of its User Planeoption. With these test suites, keycharacteristics that affect end-userexperience, such as accuracy and time-to-fix (TTF), can be analyzed.

that results are accurate andrepeatable, greatly facilitating diagnosisof performance issues and reducingthe need for expensive field trials tovalidate mobile device performance.

Lab-based testing is not yetaccepted as a substitute for the fieldtest methodology described in theFCC’s OET Bulletin No. 71. However,the test methodology described in theBulletin can be simulated by PLTS. Thestatistical analysis (required accuracyand reliability requirements for E911Phase II mobile-based solutions: 50meters for 67 percent of calls, 150meters for 95 percent of calls) may becarried out automatically by PLTS onthe results. Using this analysis,TASKIT/PLTS can also apply pass/failcriteria.

Comprehensive Test Results TASKIT/PLTS makes it easy to collectand analyze mobile device test resultsand over-the-air message logs. All testparameters and results are stored in aMicorsoft Access database for post-processing.

Storing a complete set of test dataensures the traceability of test results. This data includes detailed informationdescribing the identity andcharacteristics of the device under test.

TASKIT/PLTS is equipped with aflexible and powerful report generationfeature that uses the data to deliverresults in a variety of user-friendlymeaningful formats. Standardizedresults formats in TASKIT/PLTS enableservice providers, test labs andmanufacturers to make meaningfulcomparisons of mobile deviceperformance.

For measurements that benefit froma graphical results format, TASKIT/PLTScaptures, archives, and displaysdetailed plot data.

TASKIT/PLTSprovides detailedtest reporting in avariety of formats.

Universal Diagnostic Monitor(UDM)

The Universal Diagnostic Monitor (UDM)enables rapid test configuration byautomatically interrogating the networksettings of the device under test andsetting the corresponding testparameters. This greatly simplifies testsetup by eliminating the need tomanually enter mobile device settingssuch as NID, SID, Channel Number, andBand Class. UDM also captures the key

mobile device identity data such asESN, Model Name, Hardware Version,and Software Version that are used tolabel mobile device test results.

In addition, position location testprocedures may require run-time controlof the mobile device under test. Usingthe UDM’s powerful software router,TASKIT/PLTS automates mobile control,eliminating the need for user inter-vention when placing mobile-originatedcalls, significantly reducing test time.UDM also features the ability toremotely capture positioningmeasurements that are computedinternally by themobile when executingin MS-Based mode. The UDMsimultaneously monitors the device’sperformance. Its full-featureddiagnostic monitor can display real-time mobile device performanceparameters during test execution,resulting in complete closed-loopautomation.

UDM enablesclosed-loopautomation andlogging of mobiledevice messages.
