    Abstract: A user equipment. (UE) and a network may communicate to dynamically adapt the steering of traffic over both 3 GPP and non-3GPP accesses for uplink, downlink, or both. For example, a UE may request from the network the ability to dynamically adapt uplink traffic and the network may also apply the same traffic adaptation on downlink traffic. The UE and network may communicate dynamic traffic adaptation using traffic steering rules, e.g., via control plane NAS protocol, and with user plane signalling, e.g., via user plane PMF protocol.

    Abstract: A user equipment "UE" may be configured with a client application for data collection, contact information pertaining to a network Application Function "AF," and data collection information such as parameters, whereby the UE collects data that is specific to the UE and sends it to the AF over a user plane. The data collection parameters may include one or more of a type of data the UE should collect, data associated with one or more analytics IDs and application IDs, a data collection frequency, and a reporting frequency. The data collection information may include a processing requirement, an expiration time for the collected data, a timestamp of the data collection, and/or a correlation identifier that associates the collected data with the UE.

    Abstract: 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.

    Abstract: An overall architecture to integrate multicast and broadcast service into a general 5G core network. The architecture may provide methods and systems to switch the delivery mode of transmitting messages to User Equipment (UE)s from a unicast mode to a multicast mode. The method includes triggering events at UE, network functions, content provider or RAN node to initiate the switch process; a procedure for UE initiated switch from unicast to multicast; a procedure for network-initiated switch from unicast mode to multicast mode; and a procedure for RAN initiated switch from unicast mode to multicast mode. The architecture may also provide methods to switch the delivery mode from multicast mode to unicast mode. These methods may include triggering events at UE, network functions, content provider or RAN node to initiate the switch process; a procedure for UE initiated switch from multicast mode to unicast mode; a procedure for network-initiated switch from multicast mode to unicast mode; and a procedure for RAN initiated switch from multicast mode to unicast mode.
