ITS-S application

ITS-S application process residing in the ITS-S application entity

[SOURCE:ISO 21217:2014, 3.18]

3.2

ITS-S application process

ITS-S-AP

element in an ITS station that performs information processing for a particular application, and uses ITS-S services to transmit and receive information

Note 1 to entry: Examples of ITS-S application processes are contextual speed (ISO/TS 17426) and In-Vehicle Signage (ISO/TS 17425).

3.3

ITS-S capability

ITS-S capabilities

uniquely addressable protocol functionality

Note 1 to entry: Examples of ITS-S capabilities are Content Subscription Handler (CSH), Facilities Service Handler (FSH), Communication Profile Handler (CPH).

3.4

ITS-S facilities layer protocol data unit

ITS-FPDU

protocol data unit assembled by the Facilities Services Handler in the ITS-S facilities layer consisting of nested protocol data units exchanged between peer facilities layer services in ITS-S

3.5

ITS-S communication profile

parameterized ITS-S communication protocol stack

[SOURCE:ISO/TS 17423:2014, 3.7]

3.6

ITS-S data container

sequence of type-length-value (TLV) encoded data objects

3.7

ITS-S data header

header of the “ITS-S generic data container format” uniquely identifying the data contained in the ITS-S data containers by means of data dictionary identifiers unique in the ITS domain and the number of data objects from the data dictionary in the container

3.8

ITS-S flow

identifiable sequence of packets of a given ITS-S flow type transmitted between a source node and a destination node

[SOURCE:ISO 24102-6:2015, 3.6]

3.9

ITS-S flow identifier

ITS-S-FlowID

identifier, being unique within the ITS station, that identifies an ITS-S flow

3.10

ITS-S flow type

set of characteristics describing a data flow

[SOURCE:ISO 24102-6:2015, 3.6]

3.11

ITS-S flow type identifier

ITS-S-FlowTypeID

identifier, being unique within the ITS station that identifies an ITS-S flow type

[SOURCE:ISO 24102-6:2015, 3.6]

3.12

ITS-S generic data container format

format of an ADU exchanged between an “ITS-S application process” and a Content Subscription Handler (CSH) or between two peer CSHs containing an “ITS-S data header” and followed by a number of “ITS-S data containers”

3.13

ITS-S facilities header

header used to form an “ITS-S facilities layer protocol data unit”

3.14

ITS-S facilities service

ITS-S capability of the ITS-S facilities layer providing a service that may be applied to ADUs at the request of the source ITS-S-AP

Note 1 to entry: Examples of ITS-S facilities services are “time stamping”, “geo-stamping”.

3.15

ITS-S managed service entity

ITS-S MSE

uniquely addressable entity in an ITS-S layer comprised of a set of related ITS-S capabilities

Note 1 to entry: Examples of ITS-S managed service entities are: a communication module in the ITS-S access technologies layer (M5, cellular, etc.), a protocol suite in the ITS-S networking & transport layer (IPv6, FNTP, GeoNetworking, 6LoWPAN, etc.), and MSEGenFac, the entity comprising the generic ITS-S facilities services specified in this Technical Specification (CPH, CSH, the FSH and possibly more).
