摘要： 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.
摘要翻译：一种用于移动通信站的改进的切换测试方法，其能够通过提供切换生成和控制装置来更容易地测试切换站之间的切换功能，并且使用输出的切换信号和控制信号来处理前向硬越区切换和后向硬切换从切换发生和控制装置。该方法包括以下步骤：第一步骤，用于判断来自交换站的切换生成和控制装置的测试硬切换信号是前向硬越区切换信号还是后向硬切换信号;第二步骤，用于确定前向硬在第一步骤中当测试硬切换信号不是前向硬切换信号时，在目标交换站中执行切换测试或目标交换站中的前向硬切换测试，第三步骤，用于确定后向硬切换测试是否为在第一步骤中，当测试硬切换信号为后向硬切换信号时，在目标交换台中执行在服务交换站中执行的反向硬切换测试，以及在服务交换机中执行前向硬切换的第四步骤在第二步中在交换站中执行前向硬越区切换测试时，
