  1. IEEE ITS DSRC Application Services – P1609 Thomas M. Kurihara TKstds Management T Kurihara, TKstds Management

  2. DSRC APPLICATION SERVICES • Architecture • Project Scope • Components • Concept of Operations • DSRC Schedule • Status T Kurihara, TKstds Management

  3. ITS DSRC ARCHITECTURE APPLICATION APPLICATION RM-ME OBU RESOUCE MANAGER IEEE P1609.1 ILSME(part of P1609.3) ASME APPLICATION SERVICES IEEE P1609.2 UDP NETWORKING SERVICES (L3) ISO 21210 IEEE P1609.3 ROHC (IETF RFC 3095) LLC (IEEE 802.2) MXME MAC EXTENSION IEEE P1609.4 MLME MAC (IEEE 802.11) ASTM E2213-02 PLCP/PLME PHY T Kurihara, TKstds Management

  4. COLLABORATION • ASTM E17.51 Committee, Writing Group for ASTM 2213-02 • ISO TC204 WG16 Continuous Air interface for Long and Medium distance (CALM) M5 • National ITS Architecture FOR MORE INFO ON CALM M5 • K. Evensen, knut.evensen@q-free.comConvenor WG16.0, Editor CALM M5 T Kurihara, TKstds Management

  5. P1609.1 – Resource Manager • Project scope • Describes a Application Resource Manager for 5.9 GHz DSRC similar to that described for the 915 MHz DSRC in IEEE Standard 1455-1999 and adopted by ISO TC204 as ISO 15628:2001 • Describes services that supports DSRC applications and interfaces with the Application Layer Service (P1609.2) and Station Management Entity (SME) • Maintain compatibility with the ISO 15628 and related ISO TC204 WG 16 CALM M5 projects and to develop a workable North American DSRC Application Resource Manager T Kurihara, TKstds Management

  6. P1609.2 – Application Layer Services • Project scope • Describes application layer (L7) services for 5.9 GHz DSRC similar to that described for the 915 MHz DSRC in IEEE Standard 1455-1999 • Describes services that supports multiple protocol stacks, e.g., one representing traditional DSRC systems, TCP/IP, and streaming audio/video • Proposed standard will interface with Network Layer and Lower Layer (MAC and PHY) standards developed by ASTM and now under consideration by the IEEE 802.11 SG, DSRC T Kurihara, TKstds Management

  7. P1609.3 – IP Services • Project scope • Describes services and interfaces between multiple protocol stacks in the lower layer services of 5.9 GHz DSRC (IEEE 802.11a R/A) • Uses services built around IPv6 • Provides standard MIB support within a DSRC device T Kurihara, TKstds Management

  8. P1609.4 – MAC EXTENSION Project Scope • Describes the services that support a multi-channel system with the DSRC Medium Access Control (MAC) and physical layers via channelized queues • Provides mechanisms for switching channels and changing transmit power and data rate according to a transmitter profile registered by the Application Services (P1609.2) • Describes layer management interface for registering transmitter profiles and controlling the settings of the corresponding physical layer parameters on a per data unit basis T Kurihara, TKstds Management

  11. CONCEPT OF OPERATIONS Multiple applications interact with Application Manager APP “A” APP “B” APP “C” Application Manager (AID = 15) EFC using ISO14906 (AID = 1) Application having other AIDs Application Manager provides common interface to L7 Multiple applications can exist in parallel with the Application Manager, such as ISO 14906. DSRC Layer 7 DSRC Lower Layers T Kurihara, TKstds Management

  12. CONCEPT OF OPERATIONS Application to Application Session Link Session (DSRC Layer 7), assumes a specific Comm Session which can change during the life of the Link Back-Office Computer RSU OBU In-Vehicle Device Application Application Application Services (L7) Application Services (L7) Application Application Network Layer (L3) Network Layer (L3) In-Vehicle Network (L1- 7) Local Network (L1-7) Local Lower Layers DSRC Lower Layers DSRC Lower Layers IVN Lower Layers Local Computer Network DSRC RF Link In-Vehicle Network Comm Session (DSRC Layers 1&2) Roadside Vehicle T Kurihara, TKstds Management

  14. Current Status • Drafts for P1609.1, P1609.2, and P1609.4 circulated for WG review • Complete Sponsor Ballot 1st Quarter CY2004 • P1609.3 Draft delayed • SAE developing Data Dictionary and Message Set project, coordination pending when project is approved and underway T Kurihara, TKstds Management

  15. Team/Resources • Principal Contributing Organizations • Armstrong Consulting • TransCore • TechnoCom • Mark IV • Meetings scheduled monthly • FHWA ITS Support T Kurihara, TKstds Management
