Abstract
A handoff trial method by a mobile station that compares a pilot power strength of a base station providing communication service to the mobile station with a pilot power strength of a neighboring base station and attempts to handoff based on the comparing results. As a result of comparing, if the difference is larger than a pilot threshold to try handoff, the mobile station transmits a signal measurement message to the service base station for handoff to the neighboring base station. Also, if the mobile station communicated with a plurality of base stations tries to cut calls with the base stations, the mobile station measures pilot power strengths of the service base stations compares therebetween. As a result of the comparing, if the difference is smaller than a pilot threshold to cut call, the mobile station tries to cut call with the associated base station. The method has the effects that can reduce occurrence frequency of handoff, power consumption of the mobile station and signal processing loads of the service base station.
