SIST EN 302 636-2 V1.2.1:2013 is the Slovenian adoption of ETSI EN 302 636-2 V1.2.1 for Intelligent Transport Systems (ITS) vehicular communications. It classifies and specifies the communication scenarios supported by GeoNetworking, so system designers and reviewers can see how vehicle and roadside ITS stations are expected to exchange packets.

This standard is for people defining, implementing, or checking GeoNetworking-based ITS communications, especially where point-to-point, geographic targeting, or broadcast behavior matters in practice.

What does SIST EN 302 636-2 V1.2.1:2013 specify?

SIST EN 302 636-2 V1.2.1:2013 specifies the communication scenarios supported by GeoNetworking. Its scope is to classify those scenarios and describe the basic forms they can take.

The document is organized into:

• Clause 1: Scope
• Clause 2: References
• Clause 3: Definitions and abbreviations
• Clause 4: Classification of communication scenarios
• Clause 5: Communication scenarios
• Annex A: Advanced communication scenarios, informative

Annex	What it covers
A (informative)	An advanced example that combines central ITS station to roadside communication, R2V and V2V

What are the key requirements of SIST EN 302 636-2 V1.2.1:2013?

SIST EN 302 636-2 V1.2.1:2013 requires GeoNetworking to support a defined set of communication scenarios. In practice, this gives implementers a common model for how traffic may be addressed and forwarded.

Clause 4: how scenarios are classified

Clause 4 classifies scenarios in two ways: by connection multiplicity and addressing mode, and by direct or indirect use of the GeoNetworking protocol. For readers, this means a system design should be clear about whether communication is one-to-one, one-to-many, or based on location, and whether applications access the network directly or through another layer such as IPv6.

Clause 4 also says the number of hops is not part of the classification. A packet may pass through multiple ITS stations before it reaches its endpoint, so implementers should not assume that a scenario name implies a single-hop path.

Clause 4: the supported scenario families

SIST EN 302 636-2 V1.2.1:2013 identifies four supported scenario families:

• Point-to-point
• Point-to-multipoint
• GeoAnycast
• GeoBroadcast

For practice, this is the core mapping from application need to network behavior. Point-to-point is single source to single destination, point-to-multipoint is single source to several destinations, GeoAnycast reaches one arbitrary station in a geographical target area, and GeoBroadcast reaches all stations in a geographical target area.

Clause 4: network access modes

Clause 4 also distinguishes:

• Direct mode, where applications access the ITS network and transport layer directly
• Indirect mode, where access is through an intermediate layer such as IPv6

This matters because it affects the architecture around the GeoNetworking function, not only the packet delivery pattern.

Clause 5: the scenario descriptions

Clause 5 expands the scenarios in 5.2 to 5.5. It states that the scenarios may be combined to create more advanced cases. For implementers, this means the document is not limited to isolated textbook examples; it provides a basis for composing behaviors in real ITS deployments.

Clause 5.2 to 5.5 place the scenarios in V2V, V2R and R2V contexts. Clause 5.5 also presents GeoBroadcast as a vehicle ITS station sending to multiple vehicle ITS stations within a geographical area.

Annex A: advanced combination example

Annex A shows an example that combines central ITS station to roadside communication, R2V and V2V. The annex is informative, so it helps understanding and architecture discussion, but it is not the base specification.

What terms does SIST EN 302 636-2 V1.2.1:2013 define?

SIST EN 302 636-2 V1.2.1:2013 uses the abbreviations R2R, R2V, V2R and V2V.

• R2R means Roadside-to-Roadside.
• R2V means Roadside-to-Vehicle.
• V2R means Vehicle-to-Roadside.
• V2V means Vehicle-to-Vehicle.
• GeoAnycast means communication to one arbitrary ITS station within a geographical target area.
• GeoBroadcast means communication to all ITS stations within a geographical target area.

Who uses SIST EN 302 636-2 V1.2.1:2013?

SIST EN 302 636-2 V1.2.1:2013 is used by ITS architects, communication engineers, and integration teams working on vehicular and roadside communications. It is also useful for developers of safety and traffic efficiency applications, because the document distinguishes direct mode and indirect mode access to the ITS network.

Quality and conformity teams can use it to check whether a design uses the correct GeoNetworking scenario for V2V, V2R or R2V communication.

What changed in SIST EN 302 636-2 V1.2.1:2013 from the previous edition?

The history records earlier publication as TS 102 636-2 V1.1.1 in March 2010, then V1.2.0 in July 2013, and this V1.2.1 publication in November 2013. The document also states that it is part 2 of a multi-part deliverable, with full series details in part 1.

Which standards are used with SIST EN 302 636-2 V1.2.1:2013?

SIST EN 302 636-2 V1.2.1:2013 uses ETSI EN 302 665 as a normative reference for the ITS Communications Architecture. It also points to ETSI EN 302 636-1 as a companion part covering requirements, and ETSI TS 102 636-3 as the network architecture part.

These references matter because clause 3 takes its terms and definitions from EN 302 665 and TS 102 636-3, so the scenario descriptions are meant to be read in that wider ITS architecture context.

What does the SIST EN 302 636-2 V1.2.1:2013 document contain?

The document contains classification text, scenario descriptions, and explanatory figures for the four main communication patterns. Figures 1 to 4 illustrate point-to-point, point-to-multipoint, GeoAnycast, and GeoBroadcast examples.

Annex A adds one advanced example that combines central ITS station to roadside communication, R2V and V2V. The document also includes the reference framework, abbreviations, foreword information, and publication history needed to place the scenario definitions in the ETSI ITS series.
