Abstract

An improved handoff test method for mobile communication stations which is capable of more easily testing a handoff function between switching stations by providing a handoff generation and control apparatus and processing a forward hard handoff and a backward hard handoff using a handoff signal and a control signal outputted from the handoff generation and control apparatus. The method comprises the steps of a first step for judging whether a test hard handoff signal from a handoff generation and control apparatus of the exchange station is a forward hard handoff signal or a backward hard handoff signal, a second step for determining whether a forward hard handoff test is performed in the serving exchange station or a forward hard handoff test in the target exchange station when the test hard handoff signal is not a forward hard handoff signal in the first step, a third step for determining whether a backward hard handoff test is performed in the serving exchange station or a backward hard handoff test is performed in the target exchange station when a test hard handoff signal is a backward hard handoff signal in the first step, and a fourth step for performing a forward hard handoff in the serving exchange station when the forward hard handoff test is performed in the exchange station in the second step.
