  • Publication number: 20210306218
    Abstract: An intelligent network policy engine can be utilized to apply dynamic policy changes for microservices. For example, based on outlined service provider policies, user equipment state data, and/or network state data, the intelligent network policy engine can determine which microservices to use and/or what order to use the microservices to increase a performance of the network. The intelligent network policy engine can perform conflict resolution based on how network traffic should be treated in certain scenarios.

  • 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.

  • Publication number: 20210266990
    Abstract: A mobile edge computing (MEC) architecture can facilitate utilization of virtual multi-point non-internet protocol (IP) connections in radio access networks (RAN). Thus, the same mobile device can be addressed with multiple radio access technologies (RATs). The MEC can provide service continuity in multi-access technologies using virtual session, and the MEC can terminate a main session between a core network and the MEC, for the mobile device, via a single IP address, Based on the services and the states of the access network in the multi-access environment, the MEC can dynamically select the RAT and access point as the target to deliver the service over the RAN.

  • Publication number: 20210266369
    Abstract: Techniques for instantiating and managing microservices for use in connection with devices associated with a core network are presented. A service management component (SMC) can determine a subgroup of services to be used for a group of one or more devices based on results of analysis of characteristics and service conditions associated with the group of devices, wherein a characteristic can relate to whether a device is stationary or mobile. At a desired time(s), which can be periodically, dynamically, or upon request, SMC can instantiate or facilitate instantiating the subgroup of services to facilitate communicating data associated with the device(s) using the subgroup of services. The services can comprise a connectionless service, connection-oriented service, charging service, authentication service, UPF services, or other services. SMC can employ the connectionless service when a device is stationary, but the connectionless service can be extended to devices when they are nomadic or mobile.

  • Publication number: 20210266716
    Abstract: Peripheral devices such as wearables can link to mobile devices to access network elements. These peripheral devices can comprise a communication part and a processing part. Each of these parts, specially the processing part of the next item in a communication chain, can be multiple times larger and stronger than the previous linked item. For instance, the peripheral device can be connected to the mobile device which can be in line connected to an NodeB device. Because the processing power of mobile device can be several times stronger than the peripheral, a mobile edge computing platform and a multi-access application function facilitate sharing of processing power capabilities between the peripheral devices, mobile devices, and/or the NodeB devices.
