Abstract
A radio access network dynamically compiles history data regarding mobile wireless devices that tend to fail successful ranging, e.g., establishment of Layer 1 communication with a radio access node or base station. The history data is obtained from messages sent from the mobile device to the network which contain a count indicating the number of times the device has failed a ranging attempt. If the history (or count) data indicates that a wireless device has experienced ranging failures exceeding a threshold number of failures, the base station responsively blocks the device from attempting any additional ranging for a period of time. The period of time can be short-term period of time or a long term period of time. The methods avoid excessive use of air interface resources by excluding wireless devices which are unable to successfully range. That is, “bad” or “problem” wireless devices are excluded from access to the network.
