Patent ID: 7978642

Claim:
A radio resource control unit which monitors air interface resources and provides air interface data for radio resource management (RRM), comprising: a measurement unit configured to measure actual air interface values and a corresponding time of each measurement; a predictive processing unit configured to generate predicted air interface values before an RRM function performs an action, predictive of the effect of the action on an air interface; a default processing unit for generating default air interface values; a storage unit for storing the default values, predicted values and actual air interface measurements and corresponding measurement times; and a processing unit configured to: process the stored default values, predicted values, and actual air interface measurements and corresponding times; determine whether the actual air interface measurements are valid, wherein the actual air interface measurements are valid on a condition that they were taken within a predetermined time period before the determining or whether the RRM function is not in a transient state at the time of the determining; and provide the actual air interface measurements or an alternative value to an RRM device, wherein the alternative value is one of: the predicted air interface values or the default air interface values.
