A mobile communications device may determine whether to report information regarding operation of the mobile device on a mobile network. The determination may be based on a reporting parameter set by a network control device and received via a broadcast message from a radio access node. The mobile device may compare the value of the reporting parameter to a randomly generated number. Based on the comparison, the mobile device may determine whether or not to provide information regarding operation of the mobile device or the radio access node to the network control device. The network control device may adjust the value of the reporting parameter to control the likelihood that a mobile device will report.
