layered solution that enables continuous or quasi continuous communications between vehicles and the infrastructure, or between vehicles, using such (multiple) wireless telecommunications media that are available in any particular location, and which have the ability to migrate to a different available media where required and where media selection is at the discretion of user determined parameters by using a suite of standards based on ISO 21217 (CALM architecture) and ISO 21210 (CALM networking) that provide a common platform for a number of standardised media using ITS-stations to provide wireless support for applications, such that the application is independent of any particular wireless medium

disconnected; ITS disconnected

characteristic of a material entity that is or was equipped with communications equipment that is sufficiently physically disconnected such that the material entity is no longer able to send data to or receive data from connected entities
NOTE 1 to entry: The vehicle on-board equipment can still be present in the vehicle and can even be partially connected, but not in any operational sense.

An event based probe data message is sent only when a specific incident or event occurs. It is not transmitted in a periodic manner. The transmission of an event based probe message itself indicates that an event has occurred An event based probe message is defined as a probe message that is not triggered by a periodic occurring condition (i.e. time or distance). It is typically triggered after a defined event has occurred or an event has been detected by the vehicle on board system (i.e. low visibility or traffic jam entry). An event may be defined as simple as a change in status of a standard probe data element (i.e. fog light switching state) or can refer to a complex incident detected by a detection algorithm (i.e. traffic jam entry).
