    Abstract: A subscriber issues a message to a resource host to request subscription to multiple resources. This message may indicate identifiers of these resources, event notification criteria for each individual resource and define cross-resource notification criteria such as time window type and time window size. The resource host issues cross-resource notifications to the subscriber or its designated notification targets when expected changes on the target resources occur within a time window.

    Abstract: The present application describes a method and apparatus for managing a service in a service layer. In particular, a method describes a computer readable storage medium including instructions for managing a service in a service layer where the instructions are executed by a processor. The executed instructions cause the processor to receive a request to manage, via a service enabler function of the service layer, a change of state of the service including adding, removing, activating, or deactivating the service. The request may include a service description. The executed instructions also cause the processor to evaluate, via the service enabler function, the service description comprising identifiers of one or more services to manage. The executed instructions further cause the processor to identify one or more service capabilities in the service layer to assist in managing the one or more services identified in the service description.

  • Publication number: 20250232595
    Abstract: A method, apparatus and system for cooperatively classifying objects in an autonomous vehicle environment are provided. A controller receives data quality indicators from multiple devices. Each data quality indicator reflects quality of an instance of object sensing data held by a device. Each device determines its data quality indicators based on its own sensor data and indications of object bounding regions. The controller makes decisions based at least in part on the data quality indicators, such as decisions on which instances of object sensing data are to be used for an object classification task, which device is to perform the object classification task, any downsampling of sensor data to be performed prior to object classification, and allocations of resources for use in object classification. The decision may be made by solving an optimization problem.
