A device determines a throughput for each network slice of multiple network slices in a mobile network over a number of time windows, and predicts a future throughput for each network slice of the multiple network slices based on the determined throughput. The device determines an available bandwidth of a Radio Access Network (RAN) of the mobile network. The device allocates a respective portion of the available bandwidth of the RAN to each network slice of the multiple network slices based on the predicted future throughput for each network slice.
