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.

Content security at service layer

A device (e.g., a WTRU, network device, such as a device comprising an access and mobility function (AMF)) may perform one or more of the following actions. The device may send a registration request via non-access stratus signaling. The registration request may include a first duration. The device may receive a registration accept message. The registration accept message may indicate whether the device is to inform the network entity when the WTRU is available. The device may determine that an unavailability event has ended. The WTRU may determine whether to inform the network entity that the WTRU is available. The device may send a registration update request, for example, based on a determination that the unavailability event has ended and a determination that the WTRU is to inform the network entity when the WTRU is available. The registration update request may indicate that the WTRU is available.

Unavailability period support associated with congestion

A wireless transmit/receive unit may request, from a core network, authorization for creating one or more personal networks of one or more devices. After being granted authorization, the UE may be enabled to create a personal network and to cause a PDU session for the personal network to be established with the core network. The UE may enable members of the personal network to send data associated with the personal network via the PDU session.

Authorization, creation, and management of personal networks

Methods, devices, and systems related to serving gateway extensions for inter-system mobility in integrated small Cell and WiFi networks. An SGW may be extended into a common intermediate gateway for both LTE and WiFi access. A GTP-based 'SI a' interface between a TWAN and an SGW is introduced. The STa interface between TWAN andGPP AAA server/proxy is extended to enable selection of an SGW for establishment of the disclosed Sla interface. The extended SGW and protocols may be used to optimize inter-system mobility between LTE small cells and trusted WiFi. SGW and PDN Gateway (PGW) functionality is disclosed to support GTP-based IP Flow mobility via multi-access (LTE and WiFi) connectivity to the same packet data network (PDN). Non-access stratum (NAS), EAP, and GTP-C protocols may also be extended to include a “multi-connection” indication in addition to existing “handover” indication.

Serving gateway extensions for inter-system mobility

Network Slice Selection Assistance information (NSSA1) may be signaled between User Equipment (UE) and a network. NSSA1 sent from the network to the UE may include, for example. Operating Frequency Band (OFB) for each Single NSSAI(S-NSSA1) in the NSSAI, as well as a Radio Access Technology (RAT) Frequency Selection Priority (RFSP) index, which the network configures as a part of UE access and mobility; subscription, during a UE registration procedure. RAT restrictions may be enhanced to indicate to the UE that certain slices are not accessible via certain RATs. A UE may be provided by the network with an alternative NSSAI and corresponding OFBs for each S-NSSAI thereby indicating to the UE that these S-NSSAI would have been allowed had they been requested. A UE may be able to choose an alternative Allowed NSSAI and send a registration update request to the network.

Frequency range driven network slicing

Methods, systems, and devices may assist in enhancements to PMF protocol and new ATSSS steering modes to enable support for analytics driven or multi-USIM steering. The following functionalities are disclosed: 1) Enable UEs to use the PMF protocol to provide UE specific data to the NWDAF for analytics purposes; 2) Enable multi-USIM UEs to notify the core network over the user plane of the UE's desire to pause communications with the CN associated with one USIM so the UE can communicate with the CN associated with another USIM; 3) Define new ATSSS steering modes to support data analytics driven steering; and 4) Define new ATSSS steering modes to support Multi-USIM steering, among other things.

Traffic steering enhancements for cellular networks

Radio networks such as Public Land Mobile Networks (PLMNs), user equipment devices (UEs), servers such as Internet-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.

Server in internet-of-things communication path

A reader device may receive a request including a permanent device identifier (PDI) for an ambient-power-enabled internet of things (AIoT) device. The reader device may generate an encrypted temporary device identifier (ETDI) based on application of an encryption algorithm to the PDI. Further, the reader device may obtain a short-ETDI based on application of a bitmask to the ETDI. Also, the reader device may transmit, over a radio interface, a trigger message including the short-ETDI to the AIoT device. Moreover, the reader device may receive, over the radio interface, a random access (RA) response message including the short-ETDI from the AIoT device. In an example, the request may be an inventory request, and the inventory request may be received from an AIoT function. Further, the request may include an indication that encryption is supported by the AIoT device.

Methods and apparatus for an ambient internet of things (IoT) temporary identifier at a reader

A method and apparatus are described for supporting a two-stage device-to-device (D2D) discovery using a D2D interworking function (IWF). A D2D IWF component may be configured to perform mapping between an application running on an application server and a third generation partnership project (3GPP) network, and provide a set of application programming interfaces (APIs) to allow discovery to be provided as a service to D2D applications. An application identifier may be mapped to a 3GPP identifier. Further, a method and apparatus are described for performing client-server discovery. A first wireless transmit/receive unit (WTRU) may be configured for a listen-only operation, and a second WTRU may be configured to transmit beacons. The first and second WTRUs may perform a radio access network (RAN) discovery procedure at an access stratum (AS) layer. A method and apparatus for performing charging for D2D service using a D2D IWF are also described.

Method and apparatus for supporting proximity discovery procedures

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.

Permission based resource and service discovery

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

Core network assisted service discovery

Methods, systems, and devices may assist in policy and parameters provision to network to support the redundant transmission configuration using dual connectivity DC. In particular, a PDU session pair information (PSPI) is associated with both a first and second PDU session. The PSPI is then sent to an AMF in the network in both a first PDU session establishment message and a second PDU session establishment message. The AMF may then forward this to the RAN and first and second SMF. This allows the RAN to associate the two PDU sessions.

Enhancement to redundant transmission in 5G network

A wireless transmit receive unit (WTRU) may be configured to perform an edge application server (EAS) discovery procedure for a user session. The WTRU may be configured to determine, based on the EAS discovery procedure, that there are no available target EAS (T-EAS) instances for the user session. The WTRU may be configured to determine whether the user session supports application context relocation (ACR) to a cloud application server (CAS) using ACR configuration information (ACI). The WTRU may be configured to establish a connection with the CAS based on the ACI. The WTRU may be configured to send a notification to one or more ACR entities indicating that ACR to the CAS has been initiated. The WTRU may be configured to obtain CAS details using the ACI.

Edge-cloud application context migration

Methods and apparatuses are described herein for configuration of background data transfers (BDTs) between local area data networks (LADNs). An apparatus may receive a message indicating a request from a user equipment (UE) for a data transfer of data originating from the UE. The apparatus may send, to a database, a request for subscription information associated with the UE and a policy profile associated with the UE to determine whether there is an existing BDT policy. The apparatus may receive, from the database, a response indicating whether there is an existing BDT policy that can be re-used. The apparatus may determine, based on the received response, a BDT policy for the data transfer and a LADN to service the data transfer. The apparatus may send, to the LADN via a radio access network (RAN) node, a notification message of an arrival time and data rate for the data transfer.

Methods of managing connections to a local area data network (LADN) in a 5G network

A user equipment device (UE) initiates the creation of a dedicated bearer between a local gateway (L-GW) and a packet data network gateway (P-GW). A GTP tunnel is established to connect the L-GW, a serving gateway (S-GW), and the P-GW. The L-GW and P-GW apply Network Address Translation (NAT) and/or Traffic Flow Template (TFT) to route the traffic between the LS and a Service Capacity Server/Application Server (SCS/AS). Alternatively, an SCS-initiates the bearer creation, and an SCEF manages the creation of the GTP tunnel connection. The L-GW may be co-located with an Evolved UTRAN Node B (eNB) and/or connected to multiple eNBs which are not co-located with the L-GW.

Method and apparatus for indicating that connection enables routing of data between PDN gateway and local gateway
