METHOD AND SYSTEM FOR CONTROL OF MOBILE COMMUNICATION AND BASE STATION AND MOBILE STATION USED FOR THE DEVICE AND SYSTEM

摘要

PURPOSE: To provide a mobile communication control method and its system for lowering the information transmission rate to satisfy the prescribed communication quality when the prescribed communication quality is not satisfied, for continuing communication and for improving the service performance and also to provide a base station and a mobile station which are used for the said system. CONSTITUTION: A means is prepared to make at least one or both of a base station and a mobile station grasp the traffic state of a radio channel under communication together with a means which measures the communication quality of the radio channel and a means which decides the transmission power and the information transmission rate of a device of the transmitting side according to the traffic state of the radio channel and also to a fact whether the transmission power of the device of the transmitting side reaches the largest transmission power of the radio channel. Thus, it is possible to satisfy the prescribed communication quality by lowering the information transmission rate when the prescribed communication quality is not satisfied, to carry no communication with no forced cut and also to improve the service performance.
