channel busy ratio (CBR)

portion of sub-channels in the resource pool whose S-RSSI measured by the ITS station exceed a (pre-)configured threshold sensed over last 100 ms

portion of sub-channels in the resource pool whose S-RSSI measured by the ITS station exceed a (pre-)configured threshold sensed over last 100 ms

channel occupancy ratio (CR)

fraction of the total number of sub-channels used by the ITS station for its transmissions out of the total number of configured (granted) sub-channels over a measurement period of 1 000 ms
NOTE: This definition is access layer dependant and is specified in ETSI TS 136 214.

information-centric dissemination

a CALM station acting as a source node, also referred to as a service provider, distributes information to its neighbors; the receiving neighbors, also referred to as service user, optionally merge the information with their local information state and decide on a possible re-distribution of the (merged) information.

installer

means for installing, uninstalling and modifying applications in OBE or WAE
EXAMPLE: Software on a server that is responsible for downloading applications from a (possibly different) remote server over an IP network to OBE or WAE which is connected to the network.

bounded secured managed domain that is able to meet requirements of the ITS trust domainwithin which it wishes to participate
NOTE 1 to entry: The ITS station reference architecture is defined in ISO 21217.
functional entity comprised of an ITS-S facilities layer, ITS-S networking & transport layer, ITS-S access layer, ITS-S management entity, ITS-S security entity and ITS-S applications entity providing ITS services
NOTE 1 to entry: From an abstract point of view, the term “ITS station” refers to a set of functionalities. The term is often used to refer to an instantiation of these functionalities in a physical unit. Often the appropriate interpretation is obvious from the context. The proper name of physical instantiation of an ITS-S is ITS station unit (ITS-SU).
