    • At the time of a normal operation, a second channel change message 30b is transmitted from the AP to each terminal before a time T0 until a channel change that is included in a first channel change message 30a elapses, thereby all terminals that received this message 30b, and the AP stop changing the channel. At the time of interference occurrence, setting a time until a channel change to be filed in a third channel change message 30d to a time equal to or less than a lapse time until the channel change at the time point of transmitting this message 30d to transmit it to each terminal from the AP allows the terminal that failed to receive the message at the time of the interference occurrence to make a channel change without causing a connection to the AP to be disconnected.
    • 在正常操作时,在时间T 0之前从AP向每个终端发送第二信道改变消息30b,直到经过第一信道改变消息30a中包括的信道改变,从而所有接收的终端 该消息30b,AP停止改变频道。 在发生干扰的时刻,将通道改变的时间设定为在第三通道改变消息30d中被提交到等于或小于经过时间的时间,直到在发送该消息30d的时间点的信道改变 从AP发送到每个终端允许在干扰发生时不能接收消息的终端进行信道改变而不引起与AP的连接断开。
