A wireless communications system that creates a mobile overlay to a portion of an existing wireless communications network includes an intelligent network access controller with a processor and a non-transitory, computer-readable storage medium storing a program of machine instructions, the controller coupled to radio frequency hardware. The processor executes the machine instructions to control the radio frequency hardware to establish a mobile local control area in the portion of the existing wireless communications network, the mobile local control area having a defined boundary established through latitude, longitude, and altitude reference points describing the boundary; detect the presence of a wireless communications device within the boundary; compel the device to register with the controller by compelling the device to provide to the controller a location update of the device and device identifying information; lock the device to the controller; and deny the device access to the wireless communications network.
