Abstract: Distributed Service Layer Transactions (DSLTs) may be supported by a DSLT service at a service layer of a communications network to offload applications from the burden of managing the processing of DSLTs.

Abstract: Methods, system, and apparatuses may support end-to-end (E2E) quality of service (QoS) through the use of service layer (SL) sessions. For example, an application can communicate with a targeted device based on application specified schedule, latency, jitter, error rate, throughput, level of security, and cost requirements.

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.

Abstract: A registration procedure may allow one active and multiple inactive SL registrations to be created at different service layer entities for an application entity without adding significant overhead and burden to an application entity.

Abstract: Systems and methods are described to automate managing of relationships between IoT entities (e.g., devices, apps, users) and offloading the burden of managing these relationships from users. A Relationship Management Service (RM Service) is described herein for the autonomous establishment, modification, and tear-down of relationships between IoT entities.

Abstract: A link management service may dynamically configure one or more link-enabling attributes based on a link profile. There may be multiple types of architectures that support the link management service, such as an independent link management and integrated link management.

Abstract: Methods, devices, and systems for migration or sharing of existing M2M service layer sessions are disclosed. In one embodiment, a Session Migration and Sharing Function (SMSF) performs the migration or sharing of a M2M service layer session. Various forms of service layer session context may be used to enable the migration and sharing of M2M service layer sessions.

Abstract: A set of point-of-contact information including a service level identifier, an address, a list of interfaces, and a set of interface selection preferences for each of several entities may be used to facilitate communications among the entities by selecting a preferred interface in accordance with the set. Interface preferences may also be derived from a set of policies. The preferred interface may be resolved in accordance with the preferences of multiple entities. Messages may include an interface type parameter to be used for forwarding of the message, and message forwarding may be resolved in accordance with the parameter and the messages.

Abstract: A service layer (SL) function may be used for managing a user profile that is associated with a SL user and using this profile to automatically configure different types of devices connected to an IoT service provider's platform. A SL function may be used to support user data privacy and security when data is imported and exported between gateways or servers temporarily.

Abstract: An IoT/M2M service layer may be provided with the capability to protect user privacy. This functionality may allow the IoT/M2M service layer to anonymize user data, particularly when user data is shared with third party consumers. A privacy policy service may enable the IoT service layer system to generate anonymization (e.g., privacy) policies based on inputs such as legal obligations, subscriber privacy preferences, and an authorization level of the data consumer. Data anonymization policies may be output from the privacy policy service and may be sent to a data anonymization service, where raw data may be anonymized based on the one or more data anonymization policies. The output from the data anonymization service function may be a privatized (e.g., anonymized) version of data that may prevent the data consumer from discovering one or more identifying characteristics of a user.

Abstract: A batch of CRUD operations can be coupled with the resource discovery operation and directly conducted on the matched resources, without initiating new CRUD requests. New functionality at the Originator and Receiver can differentiate the resources for which criteria matching is applied from the resources included in the discovery/filtering results. Enhanced functionality at the Originator and Receiver can combine discovery with RESTful operations targeting a resource set different than but related the discovered resources. Other enhancements may be used to request discovery of resources in a specified relationship to those matching a filter, or to request group formation based on the result.

Abstract: Access control for RESTful operations may be provided to a centralized semantic graph store. In addition, operations may be provided over semantic triples distributed in a resource tree database. In an example, an system may use semantic descriptors distributed in hierarchical resource trees mechanisms for maintaining semantic descriptors relationship information. The mechanisms enable semantic queries to be performed within the context of specific graphs by using specific sets of sematic descriptors together. The mechanism which uses the formation of a group for semantic operation purposes also enables the use of the group resource in order to fan out semantic requests to members of the group, including members located on different service entities.

Abstract: Systems and methods are described herein to automate managing of service layer operations comprised of multiple elementary operations and offloading the burden of performing such multi-step operations from a requesting entity to the service layer. A Request Abstraction Service (RAS) is described herein for the autonomous execution of such multi-step operations. Methods and apparatuses are also described herein for a service layer framework for integrating generic and functional user interfaces as services managed by the SL on behalf of requesting entities.

Abstract: Methods, systems, and apparatuses that enable a Service Layer (SL) to support analysis of internet of things (IoT) data and enable shared access to information generated by the analysis. An analytics management service may allow SL entities to configure analytics functions for many different IoT sources of data and organize the results in a customizable manner. The SL may support coordinating the analysis of IoT data from multiple independent sources and organizing the results of the analysis.

Abstract: Service Layer adaptation may be realized through one or more adaptation rules that are programmed by server administrators in a structured but flexible manner. As part of integrating the adaptive control into its operations, a Service Layer may be configured to provide the capability to receive requests in which an adaptation rule may be specified, to provide indications through response codes returned to requestors that the Service Layer is not able to process a request due to a reduced functional state, and to send a request for more server resources or move an application, a service, or a service instance to another platform.

Abstract: Methods, devices, and systems for migration or sharing of existing M2M service layer sessions are disclosed. In one embodiment, a Session Migration and Sharing Function (SMSF) performs the migration or sharing of a M2M service layer session. Various forms of service layer session context may be used to enable the migration and sharing of M2M service layer sessions.

Abstract: An M2M Service Layer is expanded to access the services of third parties and exchange data with these third parties. The M2M Service Layer is then able to act as a proxy between M2M Devices and the third party services. The M2M Service Layer is able to present a single/consistent interface, or API, to the M2M Device and hide the details of the third party service provider from the M2M Device.

Abstract: An Authorization Verification Service (AVS) is disclosed that may be provided by an IoT/M2M service layer to registrants of the service layer for Dynamic Context Aware Authorization. The AVS may allow the IoT/M2M service layer entities to define dynamic limits for authorizing access to services or data. The limits may be set, for example, in terms of the number of allowed accesses. When an IoT/M2M registrant makes a request for data or services for which it has dynamic context aware authorization, the AVS may maintain records of the remaining accesses available.
