Описание (английский):

ISO 24103:2009 determines the logical structure of using dedicated short-range communication (DSRC) with an OSI (open systems interconnection) application layer as a CALM medium for IP communications. DSRC to which MAIL is applicable are those with an application layer compliant with ISO 15628, and the standards of such DSRC include the following: ARIB STD-T75 DSRC (Japan); TTAS.KO-06.0025 DSRC in the 5,8 GHz band (Korea); EN 12253 DSRC physical layer using microwave in the 5,8 GHz band, EN 12795 DSRC data link layer and EN 12834 DSRC application layer (Europe).

Overview

ISO 24103:2009 - "Intelligent transport systems - Communications access for land mobiles (CALM) - Media adapted interface layer (MAIL)" specifies the logical structure and protocols that allow Dedicated Short-Range Communication (DSRC) systems (with an ISO 15628-compliant application layer) to serve as CALM media for IP-based communications. In short, MAIL adapts DSRC to CALM/IP networks, enabling Internet Protocol traffic over ITS-specific short-range radio links.

Key topics and requirements

Scope and conformance

Applies to DSRC systems whose application layer conforms to ISO 15628 (examples: ARIB STD-T75, TTAS.KO-06.0025, EN 12253/12795/12834).
Conformance requires compliance with ISO 21210, ISO 21217, ISO 21218 and ISO 24102 as referenced in the standard.

MAIL architecture

MAIL is composed of two core protocol families:
- Extended Link Control Protocol (ELCP) - interfaces with ISO 15628 stacks and provides:
  - Transmission service control
  - Client/server communication control
  - Communication control management (including MIB and service registration)
- Network Control Protocol (NCP) - provides encapsulation and network control:
  - LAN control protocol (LANCP) for IP networking (focus of the standard)
  - Optional Local Port Control Protocol (LPCP) for non‑IP applications

Operation flow

DSRC L7 link establishment triggers ELCP activation.
MAIL profile exchange and capability confirmation between peers.
Optional peer authentication, NCP activation, initial NCP setup, then communication phase for IP traffic.

Interface requirements

MAIL must provide C‑SAP and M‑SAP in accordance with ISO 21218 and support defined CALM CI classes and access classes.

Applications and who uses it

Use cases

Enabling IPv6 (and other IP) communications over DSRC for ITS services such as traffic management, roadside-to-vehicle services, tolling gateways, and short-range data exchange between vehicles and infrastructure.

Stakeholders

ITS system architects and network engineers designing CALM-compliant networks
OBU (on‑board unit) and RSU (roadside unit) manufacturers implementing DSRC interfaces
Integrators deploying DSRC-based IP services (e.g., tolling, V2I communications)
Standards bodies, regulators and test laboratories validating CALM/DSRC interoperability

Related standards

ISO 15628 - DSRC application layer (normative for MAIL)

ISO 21210, ISO 21217, ISO 21218 - CALM networking, architecture, and medium service access points

ISO 24102 - CALM management

Regional/national DSRC specs: ARIB STD-T75 (Japan), TTAS.KO-06.0025 (Korea), EN 12253/12795/12834 (Europe)

ISO 24103:2009 is essential for projects that require robust, standards-based IP communication over DSRC within intelligent transport systems.
