Network Concept of Operations November 9, 2007 ITS World Congress Demo Subcommittee Meeting Presented by Justin McNew jmcnew@technocom-wireless.com +1.760.438.5115 x175 http://www.technocom-wireless.com/mobility_solutions.html
Agenda • System Architecture Definition • Data Communication Options • Application Breakdown • Schedule • Further Discussions ITS World Congress Demo Subcommittee Meeting
System Architecture ITS World Congress Demo Subcommittee Meeting
RSE Architecture/Interfacing ITS World Congress Demo Subcommittee Meeting
Data Communications • WAVE Short Message Protocol (WSMP) • Used for broadcast applications and basic requests from OBE to RSE • IPv4 based proxy and store and forward interface to back haul • IPv6 Network Based Applications • Used for applications requiring two-way data exchange • IPv4 port forwarding to back haul ITS World Congress Demo Subcommittee Meeting
WSMP • Proxy (UDP based) • “Repeating” of a WAVE Short Message received from back haul over the DSRC air interface (e.g. Signal Phase and Timing information) • WSMP payload encapsulated in a UDP datagram from back haul • WSMP payload transferred to WSM data bearer for transmission over the DSRC link • Forwarding of WAVE Short Messages received from OBEs across back haul • IPv4 port mapped to Provider Service ID • Store and Forward (replay) • For transmitting of static or pseudo static information (e.g. Signing, Travel Time info, Geometric Intersection Description) • Message uploaded (file transfer based) as often as data changes ITS World Congress Demo Subcommittee Meeting
IPv6 • DSRC Link • Provider Service ID identifies application • Announced periodically (every 100 ms) • UDP or TCP port number indicated in announcement • All OBE transmit to RSE IPv6 address with the appropriate port number • Back Haul • Port forwarding to host/server • E.g. port 7001 maps to 192.168.x.x:5001 on backhaul network ITS World Congress Demo Subcommittee Meeting
WSMP Travel Times Signal Timing Information/Traffic Signal Preemption Incident/Construction Information Work Zone Safety Notification Curve Speed Warning Notification Vehicle Restrictions GPS Corrections IPv6 Route Guidance Parking Availability and Real-Time parking reservations Arterial Traffic Data Advertising and Mobile Commerce Electronic Toll Collection/ Congestion Pricing Truck Inspection Clearance Probe Data Collection Application Breakdown ITS World Congress Demo Subcommittee Meeting
High Level Schedule • Need individual application teams to publish their detailed schedules • Need to establish procedural approach for network access • PSID assignments, IP address/port assignments, remote server connections, etc. ITS World Congress Demo Subcommittee Meeting
Discussion • General discussion regarding Booz Allen Hamilton TI application (Ram) • Expand use beyond TI • Individual applications (Jeremy, Jules, Linus, etc.) • Draft concept of operations received for ETC, Travel Information, Parking, CICAS, Signal Priority/Preemption, General Signing Apps ITS World Congress Demo Subcommittee Meeting
