Geo-anycast

geo-anycast provides data dissemination from a source node to all nodes within a specified target area
NOTE: The first station in the target area receiving the data shall forward the received data in a next hop. All other stations in the target area must not further forward the received data.

Geo-broadcast

geo-broadcast provides data dissemination from a source node to all nodes within a specified target area. Stations inside this target area may forward further the received data.

Geo-networking

geo-routing network layer protocol using addresses in the form of geo-coordinates which identify target areas of possible destination stations

geo-routing network layer protocol using addresses in the form of geo-coordinates which identify target areas of possible destination stations

Geo-unicast

geo-unicast provides unidirectional data transport from a source node to a destination node by means of multiple subsequent hops
NOTE: An identifier of the destination node shall be used, which preferably is globally unique. This station identifier shall be mapped to the actual geo-location of the destination. As the destination may be moving, this relation shall be updated frequently.

ITS-SCUID

globally unique identifier of an ITS-SCU

handover

process of switching a communications transaction in progress from one communication cell to another or between radio channels in the same cell
NOTE: Handover is used to allow established sessions to continue when mobile stations move from one cell/AP to another and as a method for minimizing co-channel interference.

head of the line

queuing discipline (also referred to as strict or fixed priority queuing), where a number of queues are served in priority order; a lower priority queue is served if all higher priority queues are empty, each queue is served in First-Come-First-Serve order, each user goes head of the line of the users of lower priorities but behind all users of equal or higher priority

heterogeneous handover

process by which a communication link is switched from one virtual communication interface to another one of a different medium type

homogeneous handover

process by which a communication link is switched from one virtual communication interface to another one of the same medium type

hybrid communication support

feature of an ITS station used to combine multiple access technologies and protocols

feature of an ITS station used to combine multiple access technologies and protocols

hybrid communications

composition of multiple access technologies and communication protocols combined to provide complementary or redundant communication channels

hybrid ITS service

ITS service that relies on hybrid communications

chaining

function performed by the Transfer Kernel to link the execution of service primitives together

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.

in-vehicle network (IVN)

generic term for a network in a vehicle which is not an ITS station-internal network

generic term for a network in a vehicle which is not an ITS station-internal network

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.
