Publication number: 20240405945Abstract: Methods and apparatuses for improving the performance and energy efficiency of Radio Access Networks (RANs) are described. Various power control schemes may dynamically adjust RAN power consumption based on fluctuations in network traffic, throughput, latency, queue sizes, and/or packet error rates with the goal of increasing energy efficiency while maintaining quality of service metrics. The power control schemes may be implemented using a PRB controller for dynamically allocating physical resource blocks (PRBs) to user devices and a CPU controller for assigning CPU power profiles based on PRB allocations for the user devices. The PRB controller and CPU controller may periodically acquire real-time telemetry data and wireless network performance information and then adjust the number of PRBs for user devices and adjust the CPU power profiles for executing RAN functions based on the telemetry data and wireless network performance information.Type: ApplicationFiled: May 31, 2023Publication date: December 5, 2024Inventors: Anuj KALIA, Yu YAN, Xenofon FOUKAS, Bozidar RADUNOVIC, Nikita LAZAREV

Publication number: 20240365427Abstract: The present disclosure generally relates to improving energy efficiency of reality-based headsets by enabling discontinuous transmission (DRX) without significantly reducing the quality of experience (QoE) of a user of the headsets when consuming digital content presented thereon. The present disclosure includes a predictive content management system that obtains consumable content (including predictive content) to be consumed on a wearable UE. The system receives, from a radio access network (RAN), discontinuous reception (DRX) configuration information indicating active and inactive periods with which the UE and RAN may communicate. The system additionally facilitates stacking consumable content, delivering the consumable content based on the DRX configuration information, and performing certain latency masking features to avoid loss of quality of the presented content.Type: ApplicationFiled: April 26, 2023Publication date: October 31, 2024Inventors: Manikanta KOTARU, Song WANG, Bozidar RADUNOVIC, Xenofon FOUKAS

Patent number: 12096270Abstract: To meet the stringent 5G radio access network (RAN) service requirements, layers one and two need to be processed in essentially real time. Thus, prompt anomaly detection is important to prevent negative impacts on customer experience, which is critical for mobile networks to meet the stringent service requirements. However, monitoring networks for anomalies is difficult due at least to (1) the resource constrained edge deployments in which the vRAN resides, (2) the variety of anomaly types and fault locations making anomalies difficult to detect, and (3) the low frequency of anomalies leading to unbalanced data sets for training, among others. The present application addresses these issues by decoupling anomaly detection at the infrastructure layer (servers, NICs, switches, etc.) from anomaly detection at the VNF layer (L1, high-DU, CU). This enables different techniques for identifying anomalies and for reducing the monitoring overhead that is tailored to each layer.Type: GrantFiled: January 18, 2022Date of Patent: September 17, 2024Assignee: Microsoft Technology Licensing, LLCInventors: Xenofon Foukas, Zhehui Zhang, Bozidar Radunovic

Patent number: 11997178Abstract: Described are examples for providing fine-grained real-time pre-emption of codelets based on a runtime threshold. A controller inserts checkpoints into extended Berkeley packet filter (eBPF) bytecode of a third-party codelet prior to verification of the third-party codelet. A device executes the codelet at a hook point of an application. The inserted checkpoints determine a runtime of the codelet. The device terminates the codelet in response to the runtime exceeding a threshold. The application can be a virtualized radio access network (vRAN) network function and the codelet can control the vRAN function or export network metrics. The application may be executed in a container management system that modifies a container for the application to mount code including a function associated with the hook point of the application to the container; detect an annotation for the container that identifies the codelet; and symbolically links the codelet to the hook point.Type: GrantFiled: May 25, 2022Date of Patent: May 28, 2024Assignee: Microsoft Technology Licensing, LLCInventors: Xenofon Foukas, Bozidar Radunovic, Sanjeev Mehrotra

Publication number: 20230421459Abstract: Described are examples for using codelets executing within applications to use machine-learning (ML) models to infer a result based on application data. The codelets may be dynamically loaded into the applications during execution. A controller verifies, based on extended Berkeley packet filter (eBPF) bytecode of the codelet, that the codelet satisfies safety requirements for execution within the application. A computing device executing the application loads the verified codelet into a library of the application. The application executes the verified codelet to apply application data to the machine-learning model to infer a result. The ML model may be implemented by the eBPF code of the codelet or the codelet may include a call to a machine-learning model of a type supported by a controller of the application and a map for a serial representation of the machine-learning model. The computing device may reconstruct the ML model based on the serial representation.Type: ApplicationFiled: September 6, 2023Publication date: December 28, 2023Inventors: Xenofon FOUKAS, Bozidar RADUNOVIC

Patent number: 11765656Abstract: A method for adjusting discontinuous reception (DRX) behavior of a user equipment (UE) to conserve energy use includes exposing a DRX application programming interface (API) that enables DRX parameters to be changed and defining a conflict resolution policy that controls when requests to change the DRX parameters should be granted. The method also includes receiving, via the DRX API, a request from an application to change a DRX parameter for the UE. The UE is in wireless communication with a base station, and the application is configured to send data to the UE via a mobile network that comprises the base station. The method also includes determining, based at least in part on the conflict resolution policy, that the request should be granted and sending a command to the base station that causes the base station to communicate a new value of the DRX parameter to the UE.Type: GrantFiled: January 24, 2023Date of Patent: September 19, 2023Assignee: Microsoft Technology Licensing, LLCInventors: Xenofon Foukas, Bozidar Radunovic, Yongguang Zhang, Landon Prentice Cox
