CASE STUDIES

Transportation

• The need– In-vehicle monitoring– Traffic management– Emergency situation reporting

• Most new cars already have an IP address and are connected to IP network

Transportation: OnStar• OnStar connects cars to NENA• NENA employs SIP to deliver

location and presence information from vehicle to PSAP

Transportation: SIP event package for vehicle info

<?xml version="1.0" encoding="utf-8" ?> <vehicle-info xmlns="urn:ietf:params:xml:ns:vehicle-info" entity="sip:44G44444H4444@avis.com" state="full" version="1111111111" > <vehicle-state> <status>open</status> <ignition>on</ignition> <fuel unit="gallon">3.0</fuel> <temperature unit="F">68</temperature> <passengers>3</passengers> <airbags>closed</airbags> </vehicle-state> <vehicle-diagnostics> <obdii DTC="P0120">Throttle Switch Malfunction</obdii> <obdii DTC="P1390">Timing Belt Skipped a Tooth</obdii> <obdii RTData="EngineCoolantTemp" unit="F">20</obdii> <obdii RTData="VehicleSpeed" unit="Miles">55</obdii> <obdii RTData="EngineRPM" unit="RPM">3257</obdii> </vehicle-diagnostics> </vehicle-info>
