    Publication number: 20200374193
    Abstract: Service Layer adaptation may be realized through one or more adaptation rules that are programmed by server administrators in a structured but flexible manner. As part of integrating the adaptive control into its operations, a Service Layer may be configured to provide the capability to receive requests in which an adaptation rule may be specified, to provide indications through response codes returned to requestors that the Service Layer is not able to process a request due to a reduced functional state, and to send a request for more server resources or move an application, a service, or a service instance to another platform.

  • Multi-channel speech separation
    Patent number: 10839822
    Abstract: Representative embodiments disclose mechanisms to separate and recognize multiple audio sources (e.g., picking out individual speakers) in an environment where they overlap and interfere with each other. The architecture uses a microphone array to spatially separate out the audio signals. The spatially filtered signals are then input into a plurality of separators, so each signal is input into a corresponding signal. The separators use neural networks to separate out audio sources. The separators typically produce multiple output signals for the single input signals. A post selection processor then assesses the separator outputs to pick the signals with the highest quality output. These signals can be used in a variety of systems such as speech recognition, meeting transcription and enhancement, hearing aids, music information retrieval, speech enhancement and so forth.

  • Distributed reactive resource and schedule management in time slotted channel hopping networks
    Patent number: 10820253
    Abstract: Wireless channels and timeslots are allocated in a distributed and reactive manner by network devices. A source device sends to neighbor devices a track discovery request indicating a destination and data bandwidth/channel and timeslot requirements. The neighbors conditionally forward the message until it reaches the destination device. The forwarded message includes information about the devices traversed by the message. Messages will not be forwarded if the recipient lacks sufficient resources to accommodate the data bandwidth requirements. The destination selects a path to be a communications track based upon characteristics of the one or more paths by which the request was received, and sends a reply back to the source device along the selected path. Once established, tracks may be kept alive, updated, and/or repaired via messaging among the devices along the track.

  • BUILDING POOL-BASED M2M SERVICE LAYER THROUGH NFV
    Publication number: 20200326989
    Abstract: It is recognized herein that existing approaches to M2M/IoT networks do not realize Network Functions Virtualization (NFV). In particular, existing M2M service layers (e.g. oneM2M) are not built, managed, or operated in accordance with NFV practices. In an example embodiment, an M2M apparatus assigns various roles to various common service entities, such that common service functions can be pooled together with one another. The roles can be migrated among common service entities to ensure that the pools are managed and controlled efficiently. Further, pool members can exit and join one or more pools.
