US: SAE Weather Info - Secure Wireless Internet (ITS)

Description:

This solution is used within the U.S.. It combines standards associated with US: SAE Weather Info with those for I-M: Secure Wireless Internet (ITS). The US: SAE Weather Info standards include upper-layer standards required to implement V2X weather information flows. The I-M: Secure Wireless Internet (ITS) standards include lower-layer standards that support secure communications between two entities, either or both of which may be mobile devices, but they must be stationary or only moving within wireless range of a single wireless access point (e.g., a parked car). Security is based on X.509 or IEEE 1609.2 certificates. A non-mobile (if any) endpoint may connect to the service provider using any Internet connection method.

Comm Profile: I-M: Secure Wireless Internet (ITS)

Level	Doc #	Standard	Description
Access		Wireless Internet Alternatives (NA)	A set of alternative standards that supports any technology that allows a mobile device (e.g., a vehicle) to connect to the Internet (or an intranet) while stationary or moving within a limited area. For example, this would include both Wi-Fi and cellular technologies among others. NOTE: Use of the WAVE Subnet should be coupled with use of IEEE 1609.3 at the TransNet Layer.
Mgmt		Bundle: SNMPv3 MIB	A bundle of standards (RFCs) that groups the common management information bases (MIBs) used to manage IP networks at the transport layer and below using SNMPv3.
Security		Secure Session Alternatives	A set of alternative standards that identifies standards that are used to establish and maintain secure Internet sessions. If an information exchange does not require encryption, the (D)TLS session can negotiate NULL encryption. NOTE: If TCP is selected in the TransNet Layer, one of the TLS alternatives must be selected from this alternative set; if UDP is selected in the TransNet Layer, one of the DTLS alternatives must be selected from this alternative set.
TransNet		Internet Transport Alternatives	A set of alternative standards that identifies the two major options for the transport layer for mainstream IP-based deployments.
TransNet		IP Alternatives	A set of alternative standards that allows for the selection of IPv4 or IPv6.

Level	Doc #	Standard	Description
Facilities	SAE J2945	SAE J2945/0 DSRC Common Design Elements	This standard defines cross-cutting material which applies to the J2945/x series including generic DSRC interface requirements and guidance on Systems Engineering (SE) content.
ITS Application Entity	SAE J2735	SAE J2735 DSRC Message Set	This standard defines the data and messages for use in DSRC (i.e., V2V, V2I, and V2D) applications. The SAE J2945 series defines additional requirements on how to use these messages.
ITS Application Entity	SAE J2945/1	SAE J2945/1 V2V Basic Safety	This standard specifies the system requirements for an on-board vehicle-to-vehicle (V2V) safety communications system for light vehicles, including standards profiles, functional requirements, and performance requirements.
ITS Application Entity	SAE J2945/3	SAE J2945/3 V2I Weather	This document specifies interface requirements between vehicles and infrastructure for weather applications, including detailed systems engineering documentation (needs and requirements mapped to appropriate message exchanges). The purpose of this SAE Standard is to enable interoperability supporting these weather applications over a communications technology agnostic interface.

Readiness Description:

A small number of minor issues. For existing deployments, consider addressing issues as needed as part of maintenance or upgrade activities. For new deployments, the solution is likely suitable for wide-scale deployment when applied to the triples it supports, though the noted issues should be considered and a path to addressing them developed, if needed, either as part of design or subsequent maintenance or upgrade activities.
