  • Patent number: 10798779
    Abstract: Multicast messaging may be managed in a machine-to-machine/Internet of things context, such as a CoAP network, via the inclusion of server selection criterion in multicast request messages and/or resource directory registration management. Server selection criteria may be explicit or implicit. An explicit criterion may be expressed, for example, as an IP address, a server identifier relative to a group context, or a Bloom filter. An implicit criterion may, for example, relate to the context of the request or the requestor, and include such information as data accuracy, data type, application, operating system, network location, geolocation, resource creation time, and resource update time. Server selection criteria may be maintained by a resource directory and/or via a user interface.

  • Publication number: 20200304510
    Abstract: Current discovery mechanisms lack capabilities, such as capabilities related to permissions associated with a given registrant for example. In an example embodiment, a registrant of a service layer can communicate with a network node that hosts the service layer. The network node may receive a discovery request for a resource from the registrant. The discovery may request include various context. For example, the context of the discovery request may be indicative of an operation that the registrant intends to perform on the resource, a role that the registrant intends to assume if the registrant accesses the resource, a location in which the registrant intends to access the resource, or a subscription plan that the registrant intends to use if the registrant accesses the resource. Based on the context of the discovery request, the network node may determine whether one or more resources at the service layer satisfy the discovery request.

  • Publication number: 20200287876
    Abstract: Existing approaches to security within network, for instance oneM2M networks, are limited. For example, content might only be protected while the content is in transit between entities that trust each other. Here, the integrity and the confidentiality of content in an M2M network are protected. Such content may be “at rest,” such that the content is stored at a hosting node. Only authorized entities may store and retrieve the data that is stored at the hosting node, and the data may be protected from a confidentiality perspective and an integrity perspective.

  • Publication number: 20200244741
    Abstract: A Data Producer may be configured to negotiate and initiate a Data Continuity service with an M2M/IoT system. This service may be for specific data sets or all data sets generated by the Data Producer. The M2M/IoT system may be configured to autonomously decide to start a Data Continuity Service for a data set of a Data Producer. The Data Producer may interact directly with an Aggregator SL to store its aggregated data set, and may also be configured to update and delete entries in this data set and start a data service on this aggregated data set. A Local SL may be configured to manage all interactions with an Aggregator SL, and the Local SL may be configured to retarget requests from the Data Producer to the Aggregator SL, including a request to start a data service on the aggregated data set.

  • Publication number: 20200221275
    Abstract: Some services offered by M2M service layers will have contact information that will be used in order to interact with applications. For example, a service layer may need to send notification messages to an application. To do this, the service layer relies on stored contact information to know how to reach the application. If the device hosting the application moves and the application changes its contact information, then the contact information that is in the service layer is stale. As a result, these services will be inefficient, or in some cases, fail altogether. Embodiments described herein provide systems and methods to enable mechanisms to update stale contact information in M2M service layers.

  • Publication number: 20200214714
    Abstract: A left atrial appendage occluder (200) comprises a sealing part (220), a fixing part (210) disposed at one side of the sealing part (220), and a connection part (230) for connecting the sealing part (220) and the fixing part (210). The radial deformation capacity of the sealing part (220) is greater than the radial deformation capacity of the fixing part (210), and/or, the axial deformation capacity of the sealing part (220) is greater than the axial deformation capacity of the fixing part (210). In the left atrial appendage occluder (200), the radial or axial deformation capacity of the sealing part (220) is configured to be greater than the radial or axial deformation capacity of the fixing part (210), thereby avoiding the situation in which the sealing part (220) is not optimally fitted with the opening of the left atrial appendage (10) when the fixing part (210) is placed inside of the left atrial appendage (10), which in turn enhances the occlusion effect.

  • Publication number: 20200220919
    Abstract: Resources on a host may be typically organized in a tree structure. In existing service layer technologies, the originators generating data may typically store their resources in default locations in such a tree, resulting in a relatively flat tree structure. As such, it may be beneficial for the service layer to provide assistance to the originators so that the originators can better structure their resources. Additionally, applications consuming the data may prefer data resources to be structured in a certain way, and may only be interested in a small subset of the hosted resources. Therefore, it may be beneficial for such applications to transmit to the service layer the resources that are of interest, and how to structure such resources. Embodiments described herein provide methods and systems to enable solutions to the problems discussed above, among others. Several aspects are introduced to enable such embodiments.

  • Patent number: 10708885
    Abstract: 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.

  • Publication number: 20200195696
    Abstract: IoT service layer capabilities may be employed to automate and simplify the service enrollment process for IoT service subscribers/enrollees. These capabilities enable virtualization of a service subscriber and the physical IoT devices, applications, data and authorized users of the subscriber into a software profile that is representative of the subscriber. Once virtualized, a service subscriber may then delegate the complexities and burden of service enrollment to an automated IoT service enrollment software function.
