BBU-b同样通过 RRU链 1、 RRU链 2将接收到的 BBU-a信息向 BBU-a 发送;
步骤三, BBU-b将通过 RRU链 1接收的信息与 RRU链 1连接的自身信 息进行比较,发明二者不一致,因此检测出 RRU链 1与自身连接错误; BBU-b 将通过 RRU链 2接收的信息与 RRU链 2连接的自身信息进行比较, 发明二 者不一致, 因此检测出 RRU链 2与自身连接错误。
BBU-a同样将通过 RRU链 1、 RRU链 2接收的信息与 RRU链 1、 RRU 链 2连接的自身信息进行比较, 经比较, RRU链 1、 RRU链 2与 BBU-a连 接错误。
经过上述检测步骤,可以确定此 RRU环型组网中, BBU和 RRU的连接 错误。
