ITS message set
set of messages designed for an ITS-related purpose
sam
fast message type for service advertisement message
common file
file containing information that is accessible to (and used by) more than one resident application
ITS-S access layer service data unit
service data unit exchanged between ITS-S access layer and ITS-S networking and transport layer
ITS-S networking and transport layer service data unit
service data unit exchanged between ITS-S networking and transport layer and ITS-S facilities layer
ITS Station Facility layer Service Data Unit
service data unit exchanged between ITS-S facilities layer and ITS-S application entity
SF
name of the interface between the ITS-S security entity and the ITS-S facilities layer
SF-COMMAND
command issued by the ITS-S security entity and sent to the ITS-S facilities layer via the SF-SAP
SF-REQUEST
command issued by the ITS-S facilities layer and sent to the ITS-S security entity via the SF-SAP
SI
name of the interface between the ITS-S security entity and the ITS-S access layer
SI-COMMAND
command issued by the ITS-S security entity and sent to the ITS-S access layer via the SI-SAP
SI-REQUEST
command issued by the ITS-S access layer and sent to the ITS-S security entity via the SI-SAP
in-vehicle network
generic term for a network in a vehicle which is not an ITS station-internal network
ITS-S networking and transport layer
layer in the ITS-S reference architecture containing OSI layers 3 and 4 that connects the ITS-S facilities layer to the ITS-S access layer
network layer and network management entity
the network layer routes the data grams to the appropriate functional unit or program addressed; it also isolates the upper layers from the different technologies that are making the connections
NOTE Network Protocols such as PPP (Point to Point Protocol), IPv6, IPX, ROHC (Robust Header Compression), and others that may be needed operate in this layer. The Network Layer implements the functionality of Global multicast, RSVP (Resource Reservation Protocol), diffserv (differentiated service), NEMO (Network Mobility), IPsec (IP Security), IP Firewall, Static Routing, Dynamic Routing Protocol NDP (Network Discovery Protocol), DHCP (Dynamic Host Configuration Protocol), and SLAAC (Stateless Address Auto-Configuration). The network Management Entity responds to commands from the CALM Management Entity to modify the routing table of the resident device so that data grams from the managed application will flow to the desired destination.
network-based multi-hopping
multi-hopping from ITS-S to ITS-S performed by a networking protocol
FAST service
a service offered by a FAST service provider via a wireless communication interface to a FAST service user, which may provide as a minimum, but not limited to this, a single information message, where the service is implemented in a provider application and in a client application
ITS-S service
communication functionality offered by an ITS-S to an ITS-S application
service channel
is a logical property of a physical wireless communication channel to run application sessions for applications with medium user priority
SN
name of the interface between the ITS-S security entity and the ITS-S networking and transport layer
SN-COMMAND
command issued by the ITS-S security entity and sent to the ITS-S networking and transport layer via the SN-SAP
SN-REQUEST
command issued by the ITS-S networking and transport layer and sent to the ITS-S security entity via the SN-SAP
PDRM instruction type specific elements
the PDRM instruction type specific elements; elements that are particular to the PDRM instruction type
NOTE The instruction types are Data Capture, Threshold and Delta.
manager
entity that is responsible for the security management and operation of applications, common files and other entities such as OBE/WAE, installers and operators
application management entity
software residing in OBE and/or WAE that manages installation, uninstallation and modification of resident applications
medium manager
all parts of an interface that are responsible for the management of the interface
NOTE In detail this is the MME and the MMAE.
interface management entity
lowest layer of the CALM management stack which is horizontally connected to the MMAE
ITS station state information
Information about state of ITS station
