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: It is recognized herein that current cellular radio access technologies lack capabilities for both long range and low power usage devices. Public LPWAN networks are described herein that may use multiple network servers. Further, the network may distribute IoT devices (e.g., LoRa end nodes) across network servers. This may allow the public IoT networks to balance loads across network servers, to allow for redundancy of network servers, to provide differentiated services across network servers, and to permit roaming of end nodes across different public IoT networks, among other things.

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: Methods and apparatus are disclosed for integrating NF discovery and application layer service capability discovery in a communications network, such as the 3 GPP NR (e.g., 5G) network.

Abstract: A network data analytics function, which may be implemented as a service, is disclosed which provides a new and improved network data analytics capability in 5G core networks.

Abstract: A Service Capability Exposure Function can be added to the UE (U-SCEF). The U-SCEF may be part of the UE's operating system (OS) and expose API's to applications that allow these applications to schedule data plane communications such as periodic sensor measurements or a firmware download. The U-SCEF communicates with an EPC Interworking Service that resides in the mobile network operator's (S)Gi-LAN. The EPC Interworking Service serves as an interface between the U-SCEF and the service capabilities that are exposed by the MNO via the SCEF. The U-SCEF may provide the EPC Interworking Service with information about the UE's anticipated communication schedule and mobility status. The EPC Interworking Service uses the services that are exposed by the SCEF to determine the optimal times for the UE to communicate, an optimal mobility management configuration, etc.

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: Radio networks such as Public Land Mobile Networks (PLMNs), user equipment devices (UEs), servers such as In-temet-of-Things servers, and core network entities may be adapted to facilitate transfers of connections of wireless devices. For example, a first PLMN may provide restricted access to a UE to assist the UE in finding a second PLMN for a full connection. Entities may be adapted to support for non-coverage related PLMN transfers, such as transfers initiated by UEs, PLMNs, servers, and core network entities, e.g., in response to changing usage, congestion, etc.

Abstract: Methods and apparatuses are described herein for sending and receiving messages using a low latency messaging service, referred to herein as a 5GMSG service, which resides in the 5G core network (5GC). In accordance with one embodiment, an apparatus may send, to a second apparatus, a first message comprising a first identifier for a third apparatus to enable the third apparatus to receive the first message. The apparatus may receive, from the second apparatus, a second message comprising a second identifier of the third apparatus. The apparatus may send, to the third apparatus, a third message comprising the second identifier. The first identifier may comprise an external public identifier of the third apparatus. The second identifier may comprise a 5G Globally Unique Temporary Identifier, a 5G Temporary Mobile Subscriber Identity (5G-TMSI), or a hashed version of a 5G-TMSI. The apparatus may receive notifications indicating that the second identifier changed.

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: When mobile terminated devices sleep, the devices might not be reachable when needed, for instance when the device is a recipient of data from a third party server. As described herein, a third party application server may inform the network that it has data to send to a particular UE or group of UEs. In an example, the mobile core network (MCN) may use information from the third party server to ensure that the UE is awake when it needs to be. For example, a given UE or group of UEs can be prevented from entering a sleep state before a data transfer is completed.

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: Methods are described that can enable resource monitoring over HTTP/2. These methods may rely on using multiple streams over persistent connections and on the HTTP/2 Push mechanism. Furthermore, a mechanism is proposed that can enable resource monitoring over multiple servers.

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: A 5G Network Architecture uses virtualization and network slicing. The user equipment (UE) interacts with an underlay network that interacts with virtual network slices. The UE interacts with the underlay network (ULN) to establish a connection to a virtual network slice. Procedures are defined to assign a new slice instance to a UE (UE initiated and ULN initiated); to change a UE Profile (UE initiated and ULN Initiated); and to change a UE's assigned slice instance (ULN Initiated).

Abstract: The present application is at least directed to an M2M gateway apparatus. The apparatus includes a non-transitory memory having instructions stored thereon for service layer online charging of a service layer event. The apparatus also includes a processor operably coupled to the non-transitory memory configured to execute a set of instructions. One of the instructions includes sending, to a service layer charging function of an M2M server, a service layer rating request message for the service layer online charging of the service layer event detected by the M2M gateway. The service layer event is triggered by an application registered to the M2M gateway and that performs a read or write operation on a resource of the M2M gateway. Another one of the instructions includes receiving, from the service layer charging function of the M2M server, a rating response including the calculated amount of service units required for the M2M gateway to process the service layer event.

Abstract: A network data analytics function, which may be implemented as a service, is disclosed which provides a new and improved network data analytics capability in 5G core networks.

Abstract: A service layer entity may register to another service layer entity and proactively request to gain access to the local services hosted by the registrar entity. A registrar entity may accept a registree entity's registration request but only grant access of its partial services to the registree entity. If a registree entity does not need to proactively request the services within its registration request message, the registrar entity decides what services may be needed by the registree entity and grants access of those services to the registree entity.

Abstract: A network node is configured to initiate a first authentication and key establishment procedure with a machine to machine (M2M) device. The network node is configured to determine a key agreement between the network node and the M2M device using the first authentication and key establishment procedure. The network node is configured to initiate a second authentication and key establishment procedure with an M2M server. The network node is configured to receive a request from the M2M server for the key agreement to be used to communicate with the M2M device using the second authentication and key establishment procedure. The network node is configured to send the key agreement to the M2M server using the second authentication and key establishment procedure.

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.
