Method for controlling a handoff in a communication system

摘要

The present invention is to provide a method for controlling a handoff in a communication system. The pilot strength of a base station and the frame quality of a forward link are measured by a mobile station. The mobile station checks whether the measured pilot strength is higher than a parameter (T-ADD) that is a threshold value for the pilot strength of the base station to which a new communication path is supposed to be added. Furthermore, it is checked whether or not the measured frame quality of the forward link is good as compared with a preset parameter (T_QUALITY). It is also checked whether or not the measured pilot strength is higher than the T_PRANKth strength of the pilots of the currently active base stations. The mobile station sends a pilot strength measurement message (PSMM) to a handoff control system in order to establish a new communication path through the base station according to the above checking results.
