Abstract: A computer-implemented method for addressing conflicts in a radio access network (RAN) includes generating, by a non-Real-Time RAN Intelligent Controller (non-RT RIC), a policy for a near-Real-Time RAN Intelligent Controller (near-RT RIC) by analyzing an activity log of several xApps, which are being executed by the near-RT RIC. The method further includes sending, by the non-RT RIC the policy to the near-RT RIC to cause the near-RT RIC, in response to receiving a request from an xApp from the several xApps to update a parameter of the RAN. The policy specifies an update the parameter based on the policy allowing the xApp to update the parameter. The policy further specifies maintaining the parameter unchanged based on the policy restricting the xApp to update the parameter.

Abstract: A method, a system, and a computer program product for optimal link selection between user equipment and new radio stations in a non-standalone network. The method includes detecting a connection attempt by a user equipment to a non-standalone network that includes at least one base station and NR stations. The method also includes receiving connection data from the UE and connecting the UE to the base station. The method further includes determining an NR station from the NR stations based on channel quality measurements relating to the NR stations and the connection data of the UE using a prediction module that uses a machine learning model to predict the NR station. The channel quality measurements include cell range, uplink performance, cell capacity, and link quality. The method also includes connecting the UE to the NR station determined by the machine learning model.

Abstract: An embodiment for coordinating edge computing in a mobile network by an MEC orchestrator. The embodiment may monitor deployment metrics and controlling deployment parameters related to a deployment of software applications on edge nodes of the mobile network The embodiment may receive an optimization report from a network orchestrator of the mobile network. The embodiment may, based on the optimization report, determine a current optimization efficiency of the mobile network. The embodiment may, if the optimization efficiency fulfils an inefficiency criterion, determine deployment suggestions having assigned one or more of the deployment parameters and being indicative of an expected response of one or more of the deployment metrics to a suggested variation of the assigned deployment parameters. The embodiment may transmit the deployment suggestions to the network orchestrator. The embodiment may, in response to receiving from the network orchestrator an indication of a selected deployment suggestion, apply the suggested variation.

Abstract: Embodiments of the invention provide a computer-implemented method that includes intercepting, using a controller of a programmable network (PN), a deployment of a control application in the PN. Responsive to intercepting the deployment of the control application, a user experience (UE) analysis is performed. The UE analysis includes determining, based at least in part on a set of digital twins, a UE impact of the control application; and, based at least in part on the UE impact, generating a UE-based control application deployment recommendation. The UE analysis further includes deploying the control application based at least in part on the UE-based control application deployment recommendation.

Abstract: A computer-implemented method according to one embodiment includes collecting device information from at least a first device, and receiving, from the first device, a first request to attach to a first base station. In response to receiving the first request, it is determined whether a signal broadcasted from the first base station includes public land mobile network (PLMN) information of a first type of telecommunication signal. In response to a determination that the signal broadcasted from the first base station includes the PLMN information, a second request is sent to a core network to connect the first device to a node associated with the first type of telecommunication signal of the first base station. In response to receiving an indication that the first device is authorized to connect, a connection is allowed to be established between the first device and the node associated with the first type of telecommunication signal.

Abstract: Computer-implemented methods for autonomous identification of rouge devices in a communications network are provided. Aspects include collecting connection trace data including connection characteristics for each of a plurality of mobile devices in communication with a communications network and aggregating the connection trace data. Aspects also include determining performance characteristics for each of a plurality of groups of the plurality of mobile devices, wherein each of the plurality of groups corresponds to mobile devices having a type approval code and comparing the performance characteristics for each of the plurality of groups. Based on a determination that the performance characteristics of one of the plurality of groups deviate from the performance characteristics of a remaining set of the plurality of groups by more than a first threshold amount, aspects include designating the type approval code associated with the one of the plurality of groups as a rogue type approval code.
