摘要： A radio resource control unit configured to determine values for use by radio resource management functions includes a measurement reception and storing unit and a measurement processing unit. The measurement reception and storing unit is configured to obtain and store air interface actual values and predictive values; and generate and store a timestamp indicating a time when each actual or predictive value is obtained. The measurement processing unit is configured to process the actual and predictive values to provide an output value; determine an occurrence of a transient period, which is a period of time when a radio link is unstable; and determine whether the actual value is valid by comparing the timestamp of the actual value to the occurrence of the transient period, and on a condition that the timestamp is within the transient period, then the actual value is determined to be not valid.
