Full title and description

Intelligent transport systems — Dedicated short range communication (DSRC) — DSRC application layer. This International Standard defines the application‑layer core (kernels and service primitives) used by DSRC‑based applications for communications between applications and lower DSRC layers.

Abstract

ISO 15628:2013 specifies the DSRC application‑layer core that provides communication tools for DSRC applications. It describes the application layer structure and framework, services for data transfer and remote operations, multiplexing, fragmentation, concatenation and chaining procedures, ASN.1/PER encoding rules for transfer syntax, communication initialization and release, broadcast support, DSRC management (including communication profile handling), and extensibility to different lower‑layer services and interfaces. The standard does not define a security policy, although it includes transport mechanisms for security‑related data.

Scope

ISO 15628:2013 defines the core application‑layer functionality for DSRC systems. It covers the parts of the application layer needed by DSRC applications as well as some intermediate functions of the OSI reference model that interact with lower layers; application‑specific processes and data are outside its scope. The standard uses services from the DSRC data‑link layer and specifies mechanisms for data transfer, multiplexing, fragmentation/concatenation, ASN.1/PER encoding, broadcast services, communication profile handling and management, and interface extensibility. It explicitly does not prescribe an overall security policy.

Key topics and requirements

• Application‑layer structure and framework for DSRC applications.
• Service primitives and kernels that application processes use to access communication services.
• Data transfer services supporting unicast and broadcast, and remote operation primitives.
• Application multiplexing procedure to allow multiple application processes to share communication resources.
• Fragmentation, concatenation and chaining procedures to handle large or segmented messages.
• Common encoding rules mapping ASN.1 abstract syntax to transfer syntax using Packed Encoding Rules (PER) as defined by ISO/IEC standards.
• Communication initialization and release procedures and support for communication profiles and DSRC management functions.
• Extensibility to different lower‑layer services and application interfaces; transport mechanisms for security‑related data (security policy itself is out of scope).

Typical use and users

Used by ITS system architects, protocol designers, automotive OEMs, roadside infrastructure vendors, telematics and communications equipment manufacturers, conformance/test laboratories, and integrators implementing DSRC‑based communications for road‑transport applications (e.g., tolling, traffic management, cooperative ITS messages). It serves as a reference when designing or testing application‑layer behavior and interfaces for DSRC deployments.

Related standards

Normative and closely related references include ISO/IEC 7498‑1 (OSI Basic Reference Model), ISO/IEC 8824‑1 (ASN.1 abstract syntax), ISO/IEC 8825‑2 (ASN.1 Packed Encoding Rules — PER), and other ITS/DSRC family standards developed under ISO/TC 204. Implementers commonly consult these standards together when specifying message encoding, transfer rules and protocol layering.

FAQ

Q: What is this standard?

A: ISO 15628:2013 is an ISO International Standard that defines the DSRC application‑layer core used by intelligent transport system applications to communicate over dedicated short range communication links.

Q: What does it cover?

A: It covers application‑layer structure and services (kernels and service primitives), data transfer and broadcast support, multiplexing, fragmentation/concatenation, ASN.1/PER encoding rules for transfer syntax, communication initialization/release, and DSRC management support; it does not define application data or an overall security policy.

Q: Who typically uses it?

A: ITS architects, vehicle OEM engineers, roadside equipment vendors, protocol implementers, test houses and system integrators working on DSRC and cooperative ITS deployments.

Q: Is it current or superseded?

A: ISO 15628:2013 (Edition 2) is published and was confirmed as the current edition; an ISO/AWI (work item) for a subsequent edition (Edition 3) has been registered for development, so users should check for a newer edition or updates before procurement or implementation.

Q: Is it part of a series?

A: It forms part of the DSRC/ITS family of standards produced by ISO/TC 204 and is intended to be used alongside other ISO/IEC standards that define encoding (ASN.1/PER) and OSI layering principles.

Q: What are the key keywords?

A: DSRC, application layer, ITS, ASN.1, PER, fragmentation, multiplexing, broadcast, communication profile, DSRC management.
