  • Publication number: 20210274412
    Abstract: In 6G, there are multiple radios that can cover the same location at any time, and yet radio failure can occur. However, a mobile edge computing (MEC) platform can increase the footprint of adjacent radios to compensate for a failed radio. To reduce the failure interruption and maintain a quality of experience for a subscriber, the MEC can utilize a virtual session capability to communicate radio change of service characteristics to a service provider. Consequently, the change in service characteristics can comprise an expanded coverage area for adjacent radios such that a mobile device of the subscriber can take advantage of the expanded coverage area without experiencing an interruption in service.

  • Publication number: 20210266907
    Abstract: A framework for dynamic network resource allocation and energy saving based on the real-time environment, radio network information, and machine learning (ML) can be utilized via a radio access network (RAN) intelligent controller (RIC). Real-time and predicted network utilization can facilitate resource and energy savings by leveraging the RIC platform. For example, a network information base (NIB) in the RIC platform can collects RAN and user equipment (UE) resource related information in real time and provides the abstraction of the access network in the real time. ML can predict real-time information about the UEs at time t based on data analytics and real time radio resource needs. The RIC can then instruct the network to reduce or increase resources.
