Description

一种射频拉远单元的节电控制方法及相关设备 技术领域
本申请涉及但不限于无线通信的基站技术领域，尤其涉及一种射频拉远单元(Remote Radio Unit，简称为RRU)的节电控制方法及相关设备。
背景技术
分布式无线基站由基带单元(Base Band Unit，简称BBU)和射频拉远单元RRU组成，二者之间由光纤或者电缆相连接。
在业务闲时，为了节约用电往往会根据业务量对基站做一些节电的处理，比如载波关断、功放关闭等。对于BBU内部的板卡，由于在主控板的近端，可以方便地控制这些板卡开关电。而对于RRU来说，处于主控板的远端，需要通过CPRI(Common Protocol Radio Interface，通用无线协议接口)通信跟基站的主控部分保持联系，由本地的CPU控制RRU工作。在任何时候RRU的CPU部分和CPRI通信部分都必须保持工作状态，否则BBU-RRU之间的通信将会断掉，一旦进入休眠则RRU将收不到唤醒的命令。所以一般RRU休眠时只能关闭功放，而信令通信部分仍然保持上电，跟BBU的主控模块保持通信，不能完全关闭，需要消耗数十瓦的电力。

本实施例中的基站的RRU侧休眠节电及启动流程的处理步骤如下：

步骤4，RRU侧译码判断电路将LOS信号做串并转换，并跟“休眠”码字对比，如果相符则电源控制电路控制为除了链路通断检测电路、译码判断电路和电源控制电路的供电电源之外的其余供电电源掉电。
步骤5，基站主控模块发命令要将RRU启动。
步骤6，链路通断控制电路通过BBU侧的通信光模块的Tx_Disable端控制该通信光模块发光或者不发光，将“唤醒”码字串发送出去。
步骤7，链路通断检测电路检测RRU侧的通信光模块检测是否收到光。
步骤8，RRU侧译码判断电路将LOS信号做串并转换，并跟“唤醒”码字对比，如果相符则电源控制电路控制步骤4中掉电的供电电源上电。
