摘要： Methods, systems, and devices may be used for assigning names and bootstrapping of security credentials for Smart Objects inside a Digital Home environment. Methods, systems, and devices for identification and security bootstrapping of a smart object within a digital home environment may include automated assignment of a device level ID and security credential for each smart object in the home using a resource directory.

摘要： Enhancements to the device management functionality within service layer architecture of a Gateway node are described. The SL application registration procedure can be enhanced for devices in support of device management. Functionality can be added to the service layer to initiate automated request notification for DM purposes. Lightweight SL Transport Protocol bindings can support sending multiple DM commands called DM Action Scripts with a specific focus on the Constrained Application Protocol (CoAP) Protocol.

摘要： CoAP network nodes may leverage context awareness to take autonomous action to adjust network operations. Context-aware procedures may be pre-configured, established by management entities, or negotiated between nodes, and include parameters for the monitoring and evaluation of data, as well has triggers for taking action. By monitoring requests to observe a resource, a node may determine when a resource should transition to multicast or unicast notification, and dynamically manage multicast group membership based on observation registrations and/or cancellations. By monitoring resource requests, a proxy may determine when to proactively refresh a cached representation of a resource. By monitoring timeouts and/or retransmissions, a client may dynamically adjust a timeout value to optimize communications.

摘要： A lightweight and extensible information model for machine-to-machine systems is disclosed. A service layer information management architecture uses three categories of atomic objects, subjects, actions, and descriptions. Information for use within the model is built using the atomic information objects. Application programming interfaces are used to perform operations and information processing by different nodes. Common service functions are used in the model as instances of a generic common service information model.

摘要： The present application describes a computer-implemented device on a network including a non-transitory memory having instructions stored thereon for registering a node with a router on the network. The device also includes a processor, operably coupled to the non-transitory memory, configured to execute the instructions of receiving, from the node over the network, a solicitation with context information including a registration start time request. The processor is also configured to execute the instructions of evaluating, at the router, whether to accept the solicitation based upon neighbor space and the received start time request. The processor is even further configured to execute the instructions of sending, to the node, an advertisement including an approved registration start time based upon the determining step.

摘要： Service layer multicast communications management may be achieved via indication by entities of multicast capabilities during service layer registration and self-subscription by the entities to the service layer. The service layer, or a managing application in communication with the service layer, may then maintain resources for multicast configurations, dynamically create multicast groups, and notify members via their self-subscription of the entities in the groups. The service layer may then further fan-out multicast messages, thereby allowing the originator of the multicast message to access recipients in multiple underlying networks without the need to configure communications directly. Fan-out may include unicasts to entities lacking multicast capabilities. Self-subscription may also be used, for example, in granting access control to a third party application.

摘要： A system is disclosed for publication and discovery of M2M/IoT services. An M2M gateway system receives resource descriptions from M2M/IoT devices. The gateway system creates for each received resource description an individual web services description language file (WSDL-I file) recording information about the resource. The gateway identifies groups of services with similar characteristics and generates for each identified group a web service description file (WSDL-G file) recording information regarding the group. The WSDL-G files are communicated to a service registry infrastructure (SRI). A consumer system queries the SRI for services satisfying particular criteria and receives WSDL-G files for groups of services that satisfy the criteria. The consumer system requests the WSDL-I files corresponding to a selected WSDL-G files from the gateway. The consumer system selects a particular service using the received WSDL-I files and uses the information in the WSDL-I file for the selected service to request the service from the corresponding M2M/IoT device.

摘要： In a machine-to-machine/Internet-of-things environment, end-to-end authentication of devices separated by multiple hops is achieved via direct or delegated/intermediated negotiations using pre-provisioned hop-by-hop credentials, uniquely generated hop-by-hop credentials, and-or public key certificates, whereby remote resources and services may be discovered via single-hop communications, and then secure communications with the remote resources may be established using secure protocols appropriate to the resources and services and capabilities of end devices, and communication thereafter conducted directly without the overhead or risks engendered hop-by-hop translation.
