Systems and methods described herein provide extended reality (XR)-aware scheduling in a radio access network (RAN). A RAN device receives downlink (DL) metadata for downlink packets in an extended reality (XR) session and uplink (UL) metadata for uplink packets in the XR session. The RAN device selects a scheduling discipline for the XR session, based on the DL metadata and the UL metadata, and implements the selected scheduling discipline for the XR session.

Systems and methods for XR-aware radio scheduling

A device may receive network data identifying reference signal data for a radio access network (RAN), control signal data for the RAN, and network key performance indicators (KPIs) associated with the RAN, and may receive energy consumption data identifying energy consumption by the RAN. The device may process the network data and the energy consumption data, with one or more machine learning models, to identify actions that reduce energy consumption at a radio unit (RU), a distributed unit (DU), or a control unit (CU) of the RAN and that control and minimize a control signal and a reference signal at the RAN. The device may cause the actions to be implemented by the RU, the DU, the CU, or the RAN to save energy at the RAN.

Systems and methods for utilizing machine learning models to conserve energy in network devices

In some implementations, a device may transmit a buffer monitoring request message, wherein the buffer monitoring request message indicates a threshold time. The device may receive a buffer monitoring response message, wherein the buffer monitoring response message indicates one or more data radio bearers (DRBs) having buffers that exceed a data threshold for a time longer than the threshold time, and wherein the buffer monitoring response message indicates respective buffer sizes. The device may receive a measurement report of a user equipment (UE) associated with a buffer size among the respective buffer sizes, wherein the measurement report is associated with secondary node (SN) candidates. The device may establish, based on the measurement report, a New Radio dual connectivity (NR-DC) for the UE by adding an SN from the SN candidates.

Systems and methods for buffer-based new radio dual connectivity setup

A system described herein may register a particular Service-Based Interface ('SBI') with a core network (e.g., a Fifth Generation core (“5GC”)). The core network may maintain information associating the system with the particular SBI. The system may request core network information, associated with the core network, from the core network. The core network may provide the requested core network information to the device via the registered particular SBI. The system may provide the core network information, received via the particular SBI, to a radio access network (“RAN”), such as an Open-RAN (“O-RAN”), which may modify RAN configuration parameters based on the provided core network information. The system may also receive requests for RAN information from the core network via the SBI, may obtain the information from one or more elements of the RAN, and may provide the requested RAN information to the core network via the SBI.

Systems and methods for analytics and information sharing between a radio access network and a core network

A method, a device, and a non-transitory storage medium are described in which a frequency and network slice selection service is provided. The service may configure network slices at a cell level which may include carrier frequencies or bands that may be ranked in terms of preference for a network slice. The service may provide frequency/band-network slice information to end devices via system information block and radio resource control messages. End devices may perform a cell search procedure and use other criteria to select and establish a network slice connection via a frequency/band of a network slice and in accordance with the service.

Method and system for network slice and frequency selection

A network device may select a first user plane function for establishing, with a user equipment, a protocol data unit session with a single flow and may receive an application function trigger associated with a first new flow for a first application of the user equipment. The network device may cause a first traffic filter to be provided to the user equipment to enable the user equipment to route first application traffic, based on the first traffic filter, to a second user plane function and a first multi-access edge computing device associated with the second user plane function.

Systems and methods for supporting multi-access edge computing using application-based quality of service flows

A method, a device, and a non-transitory storage medium are described in which an integrated access and backhaul service is provided. The integrated access and backhaul service may include an admission control service that manages admission control based on access and backhaul capacities of an integrated access and backhaul network such that access and backhaul capacities at any integrated access and backhaul device are not exceeded. The integrated access and backhaul service may include a capacity allocation service. The capacity allocation service may provision scheduling and resource allocation to support a performance metric and/or other criteria at an integrated access and backhaul device based on access and backhaul demands and capacities.

Method and system for admission and capacity control for integrated access and backhaul network

A system described herein may register a particular radio access network ('RAN')-based interface, such as a R1 interface, with a RAN, such as an Open-RAN (“O-RAN”). The system may further be associated with a particular Service-Based Interface (“SBI”) of a core network that includes a plurality of network functions (“NFs”), where each NF is associated with a respective SBI. The system may receive, via the particular SBI, a request for RAN information from one or more NFs of the core network, obtain the RAN information from the RAN via the particular interface, output the requested RAN information to the one or more NFs of the core network via the particular SBI. Associating the system with the SBI may be performed without modifying a Network Repository Function (“NRF”) of the core network.

A first User Equipment ('UE') may communicate with a second UE via a communication link to determine an operational status of the second UE. The second UE may be connected to a network via one or more communication sessions. The first UE may determine, based on the communication link, that the second UE is non-operational, and may output, based on determining that the second UE is non-operational, a request to communicate with the network via the one or more communication sessions associated with the second UE. The network may modify the one or more communication sessions to be associated with the first UE based on the request, and the first UE may communicate with the network via the one or more modified communication sessions.

A Multi-access Edge Computing (MEC) device receives first parameters associated with a user device from a first radio access network (RAN) device. The MEC device performs functions associated with an application being executed by the user device and the MEC device is co-located with the RAN device. The MEC device receives second parameters associated with the user device from a core network device. The MEC device modifies performance of the functions based on the received first and second parameters and provides third parameters associated with the user device to a second RAN device that is co-located with the MEC device for adjusting performance of a network.
