A wireless communication system includes a private LTE base station, a commercial carrier LTE base station, and a mobile wireless communications device. The mobile wireless communications device includes an LTE transceiver, a memory, and a controller coupled to the LTE transceiver and the memory. The controller stores an assigned AC value in the memory based upon a priority of use characteristic value, stores a random AC value in the memory, and determines whether access is available to the private LTE base station or the commercial carrier LTE base station. When the private LTE base station is available for access, a connection is made based upon the assigned AC value and a private LTE barring value received from the private LTE base station. When the commercial carrier LTE base station is available for access, a connection is made based upon the random AC value and a commercial carrier barring value.
