which will be upgraded to EN/ISO standards.

ITS-S architecture (ISO 21217)


The ITS-S is defined as a

Bounded

Secured

Managed

Domain.

There are many other stations used in ITS already today, which are not following the principles of BSMD. Nevertheless communications between ITS-SUs = BSME and other ITS station units has to be possible.

TS 17423 Scope


This Technical Specification • specifies requirements and objectives for communications

presented by ITS-S application process to the ITS-S management in support of automatic selection of ITS-S communication profiles in an ITS station unit (ITS-SU) specified in ISO 21217,

• specifies related optional procedures for the static and dynamic ITS-S communication profile selection processes at a high functional level.

Simplified architecture (TS 17423)


All entities (applications) using communications services from "Simplified communications" are referred to as "ITS-S application processes": (ISO 21217)• ITS-S applications (ISO 21217)• ITS-S facility applications (ISO 21217)

• CAM generator (ETSI TC IST WG1)• ITS-S management applications (ISO 21217)

• IICP (ISO 24102-4)• FSAP (ISO 24102-5)• Remote management (ISO 24102-6)

• ITS-S security applications (ISO 21217)• Other applications

Classification


ITS-S application processes:• certified for BSMD and identified by an ITS-AID

• ITS-S application, ITS-S facilities application, ITS-S management application, ITS-S security application

• authorized (=mandatory or conditional)• permitted (=optional )

• not certified for BSMD and without ITS-AID• Other application

A single ITS application certified for BSMD and identified by a value of ITS-AID might result in N ITS-S application processes of which each may be implemented by M software developers. Each implementation of each such ITS-S application process refers to the same ITS-AID, but gets its own certificate!

Comm. profile selection (TS 17423)


ITS-S application processes reside in the ITS-S applications entity, the ITS-S management entity, the IST-S facilities layer and the ITS-S management entity.

Other applications


A gateway functionality allows other applications to have restricted access to the ITS-S services of an ITS-SU.

Comm. requirements (TS 17423)










The following procedures related to data elements identified in this Technical Specification for the purpose of mapping applications to ITS-S communication profiles are identified:

• Presentation of requirements and objectives by ITS-S application processes.

• Monitoring of capabilities of communications.• Monitoring of change in regulations and policies.• Selection of ITS-S communication profiles.• Provision of additional rules and policies by user of ITS-

SUs.• ITS-S communication profile assignment for applications

which are not certified to be installed in an ITS-SU.

TS 17419 Scope


This Technical Specification illustrates and specifies "Global Classification and Management of ITS Applications" (GCMA). It • describes and specifies globally unique addresses and identifiers (ITS-

S object identifiers) which are both internal and external to ITS stations and are used for ITS station management,

• describes how ITS-S object identifiers and related technical parameters are used for classification, registration and management of ITS applications and ITS application classes,

• describes how ITS-S object identifiers are used in the ITS communication protocol stack,

• introduces an organizational framework for registration and management of ITS-S objects,

• defines and specifies management procedures,• focuses on international applicability, • is based on the ITS communication architecture described in ISO

21217.

Entities and their roles (TS 17419)


ITS-S objectEntity used in ITS related to ITS-S management that may require a globally unique identifier. Examples are ITS application objects, ITS message sets, ITS-S communication protocols, ITS-S units, ITS-S communication units.ITS-S object ownerEntity which is responsible for the specification (design), maintenance and registration of ITS-S objects, often a standards development organization or an industry special interest group such as the "Society of Automotive Engineers" (SAE). Examples are ITS application object owners, ITS message sets owners, ITS-S communication protocol owners.



ITS application objectEntity that provides an ITS service to the user as specified in ISO 21217. Examples are ITS applications and ITS application classes.ITS message setSet of ITS messages designed for an ITS-related purpose as specified in ISO 21217.ITS-S communication protocolProtocol used in a communication protocol stack of an ITS-S



ITS-S unit (ITS-SU)Physical instantiation of an ITS station specified in ISO 21217. An ITS-SU may consist of one single ITS-SCU, or several ITS-SCUs interconnected via an ITS station internal network. An ITS-SU is also referred to as "Bounded Secured Managed Entity" as specified in ISO 21217.ITS-S communication unit (ITS-SCU)Physical instantiation of a part of an ITS-SU as specified in ISO 21217.



ITS equipment manufacturerManufacturer of ITS-SUs and ITS-SCUs.ITS-S application process developerDeveloper (manufacturer) of ITS-S application processes for usage in ITS- SUs.

Identifiers and addresses (TS 17419)


ITS-AID An ITS application identifier is used to uniquely identify an ITS application or an ITS application class. It is used to advertise services, and for secure installation and real-time operation of ITS-S application processes in an ITS-SU. All ITS-S applications shall have an ITS-AID assigned to them prior to installation in an ITS-SU.ITS-AOOID An ITS application object owner identifier is used to uniquely identify an owner of specifications of ITS application objects.ITS-EMID An ITS equipment manufacturer identifier is used to uniquely identify a manufacturer of ITS equipment.



ITS-FlowTypeID An ITS-FlowTypeID is used to uniquely identify an ITS flow type. It is used in the communication profile selection process specified in CEN/ISO TS 17423. An ITS flow type is a set of communication requirements and objectives specified in CEN/ISO TS 17423 and used by the ITS-S management to select an optimum ITS-S communication profile. An ITS flow type may be identified by a globally unique well-known ITS flow type identifier (ITS-FlowTypeID).ITS-LCHID An ITS logical channel identifier is used to uniquely identify an ITS logical channel in the ITS-S communication profile selection process specified in CEN/ISO TS 17423.



ITS-MsgSetID An ITS message set identifier is used to uniquely identify an ITS message set. ITS-S applications may construct PDUs using messages from any registered ITS message set, and may also consume such messages through publish/subscribe mechanisms in ITS-SUs.ITS-MSOID An ITS message set owner identifier is used to uniquely identify an owner of specifications of ITS message sets.



ITS-PN An ITS port number is used in an ITS-SCU to uniquely identify for a given transport protocol, e.g. FNTP, an entity or protocol in the ITS-S facilities layer. Globally unique, registered well-known port numbers and local dynamically assigned port numbers are used.ITS-PRID An ITS policy region identifier is used to uniquely identify an ITS policy region (ITS-PR) in the ITS-S communication profile selection process specified in CEN/ISO TS 17423. Different types of policy regions may be distinguished.
