SU06: Object Registration and Discovery

This service package provides registration and lookup services necessary to allow objects to locate other objects operating within the Connected Vehicle Environment.

An object registry is like a phone book for all the connected centers, systems, and equipment in the transportation system (the "objects"). In this service package, each object registers itself with the ORDS and tells the registry where it lives in the communication network (e.g., host, port, node name) and information about the services it provides - information that other objects can use to determine the type of service, the geographic scope of the service, and other information that helps users of the registry to make informed decisions about which object(s) support a needed service or information stream. This is the "Discovery" part of the service. Connected objects can use the registry to find (discover) objects that can be used to get needed information or services.

Includes Physical Objects:

Physical Object Class Description
ITS Object ITS The general 'ITS Object' includes core capabilities common to any class of object.
Object Registration and Discovery System Support The 'Object Registration and Discovery System' represents one or more center-based applications that provide registration and lookup services necessary to allow objects to locate (for communications purposes) other objects operating within the Connected Vehicle Environment. These registration and discovery services are support services that enable other applications.
ORDS Operator Support The 'Object Registration and Discovery System Operator' represents the person or people that monitor and manage the Object Registration and Discovery System.
Vehicle OBE Vehicle The Vehicle On-Board Equipment (OBE) provides the vehicle-based sensory, processing, storage, and communications functions that support efficient, safe, and convenient travel. The Vehicle OBE includes general capabilities that apply to passenger cars, trucks, and motorcycles. Many of these capabilities (e.g., see the Vehicle Safety service packages) 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. The radio(s) supporting V2V and V2I communications are a key component of the Vehicle OBE. Both one-way and two-way communications options support a spectrum of information services from basic broadcast to advanced personalized information services. Route guidance capabilities assist in formulation of an optimal route and step by step guidance along the travel route. Advanced sensors, processors, enhanced driver interfaces, and actuators complement the driver information services so that, in addition to making informed mode and route selections, the driver travels these routes in a safer and more consistent manner. This physical object supports all six levels of driving automation as defined in SAE J3016. Initial collision avoidance functions provide 'vigilant co-pilot' driver warning capabilities. More advanced functions assume limited control of the vehicle to maintain lane position and safe headways. In the most advanced implementations, this Physical Object supports full automation of all aspects of the driving task, aided by communications with other vehicles in the vicinity and in coordination with supporting infrastructure subsystems.

Includes Functional Objects:

Functional Object Description Physical Object
ITS Management Support 'ITS Management Support' provides management of the ITS Object. This includes management of regulatory information and policies, management of application processes, management of communication system configuration and update management, communications interfaces, protocol-specific techniques to ensure interoperability such as service advertisements, communications congestion management and interference management, local device states and communications information, billing management, fault management, service level and performance monitoring. ITS Object
Object Registration and Discovery 'Object Registration and Discovery' facilitates the registration of services by the respective service providers and the subsequent query-based discovery of these registered services. Many of the services offered by roadside or center-based service providers operating within the project geographic boundary will require an advertisement of their existence and cyber location to potential users; which consist primarily of PIDs and vehicles, but could include roadside or other center based services. Object Registration and Discovery System
Vehicle Support Services 'Vehicle Support Services' provides foundational functions that support data collection, management, and distribution. It coordinates with Support subsystems to maintain necessary registrations with respect to location and scope. Vehicle OBE

Includes Information Flows:

Information Flow Description
object discovery Represents the interactive discovery of network communications related information by any end entity, querying the ORDS. Information exchange could be as simple as a Domain Name Service (DNS) query, or it could include service and service metric information.
object registration Represents the provision of information related to communications, service and service metric information from a service provider end entity to the ORDS.
ORDS operations information presentation Presentation of information to the ORDS Operator including current operational status of the Object Registration and Discovery Service.
ORDS operator input User input from the ORDS operator including requests to monitor current system operation and inputs to affect system operation.
service advertisement An advertisement of available services and identification of how those services may be accessed (e.g., RF parameters, identifiers, etc.). Services include network services such as IPv6 routing, public roadside services such as intersection safety, back office services including situation data services and security credentials, or private services.

Since the mapping between objectives and service packages is not always straight-forward and often situation-dependent, these mappings should only be used as a starting point. Users should do their own analysis to identify the best service packages for their region.

This information will be available to all C-ITS devices. C-ITS connectivity is predicated on device connectivity. The information contained within this flow is critical to that. Without correct and timely networking information, other C-ITS flows will fail, which is why this flow is so critical. C-ITS connectivity is predicated on device connectivity.
