Abstract
A handoff method. A mobile station calculates and records the strength of a pilot signal from a cell as reference strength if a handoff occurs in a first system. The mobile station further adjusts the reference strength according to the effect caused by forward and reverse links between a base station and the mobile station, and performs a handoff between the first and a second system if the strength of the pilot signal reaches the reference strength.
