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

Railroads: Multiple devices, multiple networks
In Conclusion
• SIP is not only for telecom
• SIP event mechanism can be used for M2M
communication
• Car, trains communicate using SIP
• Any IP devices can communicate using SIP
• Voice and Video is the bonus in such
communication
