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.

1. A method for controlling a handoff in a communication system, comprising:(a) measuring a pilot strength of a base station by a mobile station and measuring a frame quality of a current forward link by the mobile station; (b) checking whether said measured pilot strength is higher than a parameter (T-ADD) that is the threshold value of the pilot strength of said base station in which a new communication path is established, and checking whether said frame quality of the forward link is good as compared with a prescribed parameter (T-QUALITY) and determining whether the measured pilot strength is higher than a prescribed threshold value of a pilot power ranking, wherein the prescribed threshold value must be relatively satisfied as compared with a pilot strength of the base station; and (c) when said measured pilot strength is higher than said parameter (T-ADD) and said frame quality of the forward link is not good as compared with the prescribed parameter (T-QUALITY), in order to establish a new communication path, transmitting a pilot strength measurement message (PSMM) from said mobile station to a handoff control system through said base station.
