A device may receive a request to establish a communication session with a network. The request includes first bearer information regarding a bearer and first network slice information regarding a network slice of the network. The device may generate a first priority value, associated with the request, based on the first bearer information and the first network slice information. The device may obtain second bearer information regarding active bearers associated with existing communication sessions and second network slice information regarding one or more network slices, of the network, associated with the active bearers. The device may generate second priority values associated with the active bearers based on the second bearer information and the second network slice information. The device may compare the first priority value and the second priority values. The device may preempt one or more of the active bearers based on the comparison.
