location and time Quintuple

Bidirectional?: False

location and time (A-Interconnect): This CVRIA application interconnect encapsulates all of the Layer 2 information flows between the 'Vehicle Support Services' application object and the 'Vehicle Location and Time Data Source' physical object. In this case, there is only a single Layer 2 flow associated with this interconnect, so the Layer 1 application interconnect name and the Layer 2 information flow name are both 'location and time'. This application interconnect is uni-directional since the underlying layer 2 information flows go from 'Vehicle Location and Time Data Source' to 'Vehicle OBE'.

Vehicle Location and Time Data Source (Source Physical Object): The 'Vehicle Location and Time Data Source' provides accurate position information for vehicle-based mobile devices. While a Global Positioning System (GPS) Receiver is the most common implementation, this physical object represents any technology that provides a position fix in three dimensions and time with sufficient accuracy.

Vehicle OBE (Destination Physical Object): The Vehicle On-Board Equipment (OBE) provides the vehicle-based processing, storage, and communications functions necessary to support connected vehicle operations. The radio(s) supporting V2V and V2I communications are a key component of the Vehicle OBE. This communication platform is augmented with processing and data storage capability that supports the connected vehicle applications.

In CVRIA, the Vehicle OBE includes the functions and interfaces that support connected vehicle applications for passenger cars, trucks, and motorcycles. Many of these applications (e.g., V2V Safety applications) apply to all vehicle types including personal vehicles, commercial vehicles, emergency vehicles, transit vehicles, and maintenance vehicles. From this perspective, the Vehicle OBE includes the common interfaces and functions that apply to all motorized vehicles.

Vehicle Support Services (Destination Application Object): 'Vehicle Support Services' provides foundational functions that supports data collection, management, and distribution. It coordinates with Object Registration and Discovery to acquire necessary communications information. It maintains the necessary security credentials, authorizations, and associated keys to support communications in the connected vehicle environment.
