The invention discloses a communication control method based on priority management, which is applied to a mobile communication system which is allocated with a measurement clearance and is in a DRX mode; the method comprises the following steps: relative parameters of the DRX mode are obtained, weather the priority of the measurement clearance is higher than the priority of data transmission is determined, if yes, the UE measures the quality of a communication channel of the adjacent district in the measurement clearance, if not, the UE and eNB carry out data transmission under the DRX mode;therefore, by leading in the priority management between the measurement clearance and the data transmission, the UE can carry out data transmission in the district smoothly while obtaining enough pilot frequency or different system measurement parameters, thereby overcoming the problems that the priority of the measurement parameters leads a data package to be lost and redundant dispatching demand processes are initiated by the UE in the existing proposal.
