Patent number: 11601882Abstract: 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: June 15, 2021Date of Patent: March 7, 2023Assignee: Microsoft Technology Licensing, LLCInventors: Xenofon Foukas, Bozidar Radunovic, Yongguang Zhang, Landon Prentice Cox

Publication number: 20220386302Abstract: Aspects of the present disclosure relate to allocating RAN resources among RAN slices according to reinforcement learning techniques. For example, a network slice controller (NSC) may generate a RAN resource allocation and associated expected slice characteristics may be determined for each slice based on the RAN resource allocation. Resources of the RAN may be allocated accordingly, such that resulting actual slice characteristics may be observed and compared to the expected slice characteristics. A reward may be generated for the resource allocation, for example based on a difference between the expected and observed slice characteristics. RAN resource allocation and slice characteristic forecasting may be adapted according to such rewards. As a result, RAN resource allocation generation may improve, even in instances with changing or unknown network conditions.Type: ApplicationFiled: May 28, 2021Publication date: December 1, 2022Applicant: Microsoft Technology Licensing, LLCInventors: Bozidar RADUNOVIC, Xenofon FOUKAS, Manikanta KOTARU, Anuj KALIA

Publication number: 20190385347Abstract: Graph partitioning for massive scale graphs is described, such as for graphs having vertices representing people and edges representing connections between people in a social networking system; or for graphs where the vertices represent other items and the edges represent relationships between the items. In various embodiments a graph data allocator receives a graph vertex and its edges and allocates the vertex to one of a plurality of clusters each associated with one or more computing devices. In various embodiments the allocation is made by optimizing an objective function which takes into account both a cost of edges between clusters and a cost related to sizes of the clusters. In some examples the cost related to sizes of the clusters comprises a convex function applied to each of the cluster sizes. In examples, computations on the graph data are carried out with reduced runtimes and communications cost.Type: ApplicationFiled: December 20, 2018Publication date: December 19, 2019Inventors: Milan VOJNOVIC, Charalampos E.
