Abstract: A wireless transmit/receive unit (WTRU) may establish a connection with a non-3GPP device. For example, the non-3GPP device may be a smart watch a tablet, a health monitoring device, or an appliance. The connection may be established via a wireless communication protocol, such as WiFi or Bluetooth. The WTRU may establish a connection with a cellular network. The non-3GPP device may lack the capability to connect directly to the cellular network. The WTRU may receive a request from the non-3GPP device for access to the cellular network. The WTRU may perform an authentication procedure with the network using information from the request, such as an identity of the non-3GPP device. After authentication, the WTRU may route data traffic between the non-3GPP device and the cellular network.

Abstract: Methods and apparatus are described for configuring desired network capabilities in a service-based network, including a method for a UE to initiate a network capability based registration to configure its desired network capabilities, a method for UEs to initiate a network capability based registration update when UEs are already registered to the network and want to dynamically re-configure their network capabilities, and a method for a network capability based UE configuration update, which allows NFs or ASs to initiate updating the network capabilities in a network slice for the UE.

Abstract: A method of multi-hop relay chain formation in a wireless communication network includes discovering, via a remote electronic device, one or more other electronic devices in communication range of the remote electronic device; selecting one of the discovered electronic devices as an relay electronic device for communicating in the multi-hop relay chain; after selecting the relay electronic device, transmitting, via the remote electronic device, a request to establish a PC5 link; and establishing the PC5 link with the remote electronic device to join or form the multi-hop relay chain within the wireless communication network.

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.

Abstract: Profile based services and content can assist with the backward and forward compatibility of conventional service layers or the like. Using a profile to manage content and access to services offered may reduce the overhead or processing associated with providing those value added services by service layers.

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: 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: 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.

Abstract: A common Data Analytics Service (DAS) at service layer is designed to use underlying existing/future data analytics technologies or tools and provide them to service layer entities that need those data analytics operations with uniform access approach. A general operation framework/interface design is used for enabling DAS and the operation details within DAS. Related procedures for interacting with DAS, including the new parameters in service layer request/response messages can be used.

Abstract: Some underlying networks such as Low-Power Wide-Area Networks (LPWAN) have limited communication bandwidth and strict requirements on maximum message size. These requirements may pose a challenge for data or resource exchange between two service layer (SL) entities, for example, because resource representations to be exchanged may have too large a size to be supported by the underlying networks. In some cases, traditional data compression algorithms can be used to alleviate this problem to some degree, but it is recognized herein that there are associated computation costs due to compression and decompression that may not be affordable for constrained IoT devices. Various embodiments described herein address this problem, among others by defining a Resource Representation Common Part (RRCP) and storing it at the service layer. In some cases, the RRCP is not transmitted between SL entities, thereby reducing SL message sizes to cater to the constraints of underlying networks.

Abstract: It is recognized herein that capabilities are lacking related to how different users can be authenticated on top of an existing subscription authentication. In some examples, a user-centric authentication layer may be supported on top of an existing subscription authentication, such that different users may use the same user equipment (UE) with customized services, and different users of devices can be identified behind a gateway with a 3GPP subscription (without the devices having a dedicated 3GPP subscription). Further, a user identifier may be linked to a subscription to access 3GPP services via non-3GPP access.

Abstract: An electronic device is configured to transmit, to a wireless network, a link request message requesting a user identifier be associated with an identifier corresponding to the electronic device; receive, from the wireless network, a registration response confirming that the user identifier has been associated with the identifier corresponding to the electronic device; and receive, from the wireless network, updated configuration information for the electronic device, wherein at least part of configuration information is associated with the user identifier.

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.
