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

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.
