Abstract: A device may receive network data identifying uplink/downlink packet loss percentage, uplink/downlink jitter, uplink/downlink latency, and uplink/downlink packet throughput associated with a slice of a network, and may set an uplink value for each of the uplink packet loss percentage, the uplink jitter, the uplink latency, and the uplink packet throughput. The device may multiply the uplink values by corresponding uplink weights to calculate an uplink cost, and may set a downlink value for each of the downlink packet loss percentage, the downlink jitter, the downlink latency, and the downlink packet throughput. The device may multiply the downlink values by corresponding downlink weights to calculate a downlink cost, and may calculate a total cost based on the uplink cost and the downlink cost. The device may cause another slice, with the same attributes as the slice, to be instantiated when the total cost satisfies a threshold for a time period.

Abstract: A device may receive a simulation start command and status data indicating that network elements are ready to process data for multiple simulations.

The device may define a verification start time, for the multiple simulations, based on the simulation start command, the status data, the time slot, and a system frame number being zero, and may define a network frame number that increments when the verification start time changes from zero to one. The device may cause the multiple simulations to be executed by the network elements, based on the time slot, the system frame number, and the network frame number, and may receive synchronized simulation results based on causing the multiple simulations to be executed by the network elements.

Abstract: Systems and methods limit communication of redundant telematics data in V2X systems. A communications management device receives telematics data from multiple sources in a service area and calculates a trajectory each of the objects identified by the telematics data. The communications management device selects high vulnerability trajectories based on the calculated trajectories and identifies when the telematics data from different sources, of the multiple sources, corresponds to a same vehicle. When duplicate sources are determined to provide tracking data corresponding to the same vehicle, the communications management device reports (to a collision avoidance system) the tracking data from only the most accurate of the duplicate sources.
