5G admission by verifying slice SLA guarantees

One or more hardware-based non-transitory computer-readable memory devices storing computer-executable instructions which, upon execution by one or more processors disposed in a computing device, cause the computing device to:

• provide a channel state information (CSI) prediction model to predict CSI for new connectivity requests to one or more radio access network (RAN) slices in a 5G (fifth generation) network from applications executing on user equipment (UE), wherein the new connectivity requests include identification of a RAN slice to which admission is sought;
• use the predicted CSI to determine whether granting admission to the application making the new connectivity request provides for all UE connections to the identified RAN slice to continue to meet applicable service level agreement (SLA) guarantees;
• use the predicted CSI to determine whether granting admission to the application making the new connectivity request provides for new connectivity to the identified RAN slice to meet applicable SLA guarantees;
• grant admission to the identified RAN slice responsive to a determination that of the identified RAN slice continuing to meet applicable SLA guarantees and further responsive to the determination of new connectivity to the RAN slice meeting applicable SLA guarantees;
• and
• deny admission to the identified RAN slice either responsive to a determination of the identified RAN slice not continuing to meet applicable SLA guarantees or responsive to the determination of new connectivity to the RAN slice not meeting applicable SLA guarantees, and
• wherein the CSI prediction model comprises a predictive propagation model using reinforcement learning based on CSI data from one or more online or offline sources, and
• wherein the online sources of CSI data comprise CSI feedback from a population of UE that is engaged in current communications sessions over the 5G network, the CSI feedback reporting dynamic channel conditions between radio transmission points in the RAN and the UE.

A computing device, comprising:

• at least one processor;
• and
• at least one hardware-based non-transitory computer-readable storage device having computer-executable instructions stored thereon which, when executed by the least one processor, cause the computing device to
• dynamically configure a radio access network (RAN) in a 5G (fifth generation) network by allocating RAN resources among a plurality of slices in the RAN in response to changing traffic on the slices of the RAN from user equipment (UE) to meet one or more service level agreement (SLA) guarantees that are applicable to the RAN slices based on current UE connectivity;
• receive a request made by an application on a UE for admission to a RAN slice that is identified in the request;
• attempt to identify a RAN configuration for which an allocation of RAN resources among the RAN slices enables the identified RAN slice to continue to meet all applicable SLA guarantees should the admission request from the application be granted;
• grant admission to the application to the identified RAN slice if the attempt to identify a RAN configuration is successful;
• dynamically reconfigure the RAN by reallocating RAN resources in accordance with the successfully identified RAN configuration;
• waiting for a predefined time interval before granting admission of the application making the request in response to an initial determination of the identified slice not meeting the SLA guarantees responsively to the application in the request being admitted to the identified slice;
• and
• after waiting the predefined time interval, making a subsequent determination whether the identified RAN slice meets SLA guarantees responsively to the application making the request being admitted to the identified slice.
