TPEG2 - Wide Area Broadcast

Description:

This solution is used within Australia, the E.U. and the U.S.. It combines standards associated with TPEG2 with those for C-X: Wide Area Broadcast. The TPEG2 standards include upper-layer standards required to support multi-modal information services.. The C-X: Wide Area Broadcast standards include lower-layer standards that support one entity broadcasting information to all wireless devices over an area that covers at least a metropolitan area without any expectation of acknowledgement or response; security is provided by the upper-layers.

Comm Profile: C-X: Wide Area Broadcast

Standards in Profile:

Level	Standard	Description
Access	WAW Broadcast Alternatives	A set of alternative standards that describes various types of wide-area wireless broadcast mechanisms.
Mgmt	Proprietary	A proprietary mechanism to provide services for this layer.
Security	Proprietary	A proprietary mechanism to provide services for this layer.
TransNet	Proprietary	A proprietary mechanism to provide services for this layer.

Data Profile: TPEG2

Facilities	No Standard Needed	Not Needed	The services related to this portion of the stack are not critical within the scope of this solution.
ITS Application Entity	ISO 21219-15	ISO 21219-15 TPEG2 - Traffic Event	ISO/TS 21219-15 specifies the TPEG application: Traffic Event Compact. This application has been specifically designed to support information about traffic events (e.g. road works, traffic jams). A specific form of traffic events are local hazard warnings which, being safety-related messages, are sent with high priority to warn a driver that may encounter dangerous situations (e.g. black-ice, accident beyond curves, obstacles on road, etc.) unexpectedly.
Mgmt	ISO 21219-6	ISO 21219-6 TPEG2 - Message Mgmt	ISO 21219-6 adds a basic toolkit definition to the ISO 21219 series specifying the Message Management Container (MMC), which is used by all TPEG applications to provide information about the handling of messages on the TPEG client side. The MMC holds administrative information allowing a decoder to handle the message appropriately. This information is not aimed at the end user. The MMC is a toolkit and not a stand-alone application but is included in TPEG applications.
Security	ISO 21219-24	ISO 21219-24 TPEG2 - Light Encryption	ISO/TS 21219-24 defines the LTE encryption mechanism for TPEG Service Data Frames. It has been specifically designed for use with Business-to-Business (B2B) business models. The objective of this document is to provide a simple to use, yet effective Conditional Access mechanism for TPEG including encryption for use with both broadcast and/or point-to-point delivery. For both service providers and device manufacturers, a standardized conditional access mechanism is beneficial to avoid a proliferation of proprietary methods with multiplied implementation effort and lead times.

Readiness Description:

One significant or possibly a couple minor issues. For existing deployments, the chosen solution likely has identified security or management issues not addressed by the communications solution. Deployers should consider additional security measures, such as communications link and physical security as part of these solutions. They should also review the management issues to see if they are relevant to their deployment and would require mitigation. For new deployments, the deployment efforts should consider a path to addressing these issues as a part of their design activities. The solution does not by itself provide a fully secure implementation without additional work.
