具体实施方式
图1为一种通信系统架构图，该本申请可以应用于如图1所示的RRU-BBU场景，但并不以此为限。
如图1所示，该场景架构可以包括：基带处理单元(Building Baseband Unit，简称BBU)、RRU集线器(RHUB)以及多个RRU。
其中，RRU可以是分布式基站的组成部分。上述架构中RRU可以是微RRU(pico-RRU，简称pRRU)。
多个RRU可以根据具体的场景部署在各个位置，以便于给不同位置的终端提供服务。例如一般中大型建筑物室内面积达到2万平方米～5万平方米，甚至有达到10万平方米，要完成这样一套室内覆盖方案，部署所需要的pRRU将达到几十至数百个。
多个RRU通过RHUB与BBU连接，BBU可以控制各个RRU的开关状态，也就是控制各个RRU的上下电。可选地，BBU通过RHUB控制各个RRU的上下电。
本申请中，针对在RRU数量较多的情况下如何减小耗能的问题，提出来一种将空闲RRU下电的方法，不同于目前只关闭RRU部分功能的方法，可以更好地减少能耗。
图2为本申请提供的一种射频拉远单元的控制方法流程示意图，该方法的执行主体可以是BBU。如图2所示，该方法包括：
S201、监测预设监测范围内每个上电状态RRU下是否接入有终端。
某个室内场景下的所有RRU可以由一个BBU管理，BBU启动监测后，会检测自己管理范围内所有上电状态的RRU，可选地，以逻辑小区为监测对象进行监测管理范围内所有逻辑小区下各个上电状态RRU下是否接入有终端。一般刚启动监测时，管理范围内所有RRU都处于上电状态。
具体监测每个RRU下是否接入的有终端，如果没有任何终端，说明这个RRU目前不需要为终端提供服务，处于空闲。
S202、确定预设监测范围内在预设时长中无接入终端的上电状态RRU。
S203、将上述预设时长中无接入终端的上电状态RRU中除预设常开RRU之外的RRU下电。
其中，某些上电状态RRU在预设时长内一直保持没有终端需要服务，即一直处于空闲，则可以直接下电。即可以将没有终端接入的所有上电状态RRU中除预设常开RRU之外的RRU下电。
为了灵活控制监测范围内RRU的开关状态，需要设定一些常开RRU，这些常开RRU即使没有任何终端接入也保持上电状态，以便于其他RRU下电后，如果有终端接入常开RRU，BBU再控制其他RRU上电。一般地，可以预先根据RRU的部署位置设定一个或多个常开RRU，将预设常开RRU的标识存储在BBU中，预设常开RRU一般设定在监测范围的入口处，例如门口、走廊等关键位置，这些位置一般是用户进入监测范围后先可能经过的位置，以保证BBU及时获知有终端接入，进而在为终端提供服务的同时将其他必要RRU上电为用户服务，在节能的同时不影响用户业务。
本实施例中，监测预设监测范围内每个上电状态RRU下是否接入有终端，确定预设监测范围内在预设时长中无接入终端的上电状态RRU，将上述无接入终端的上电状态RRU中除预设常开RRU之外的RRU下电，实现了可以根据监测情况将暂时空闲的RRU直接下电以节能，同时又保留一些常开RRU不下电，以便于灵活根据终端的接入再将用户所需的RRU上电，在节能的同时保证用户服务。
可选地，监测预设监测范围内每个上电状态RRU下是否接入有终端，可以是，在预设监测时间段内监测预设监测范围内每个上电状态RRU下是否接入有终端。
预设监测时间段是预先确定的低话务时段，低话务时段可以表示需要服务的终端数量很少或没有。具体地，对于大部分室内场景，在一些时间段内可能需要提供服务的用户较多，这些时间段不是低话务时段，无需进行监测，将所有RRU上电即可；在另一些时间段内可能场景内的用户量极低，即处于低话务时段，就可以开启监测，以便可以将一些空闲的RRU下电实现节能。
在此以一些常见场景举例说明：
(1)交通枢纽地带，例如：飞机场、火车站、汽车站，这些场景一般白 天用户量巨大，所有RRU上电，可以设定晚上场地关闭时间至早上场地开启时间为预设监测时间段，这段时间内用户量会减少、甚至没有，开启监测后可以将大部分RRU下电以节能。
(2)大型商场、超市等公共场所，以及写字楼、学校等工作学习场所，这些场所一般有固定的用户流动规律，像商场有固定的开门时间、歇业时间，写字楼有上班时间和下班时间，但是歇业时间/下班时间也可能有员工或其他必要人员进入活动，那么就可以根据用户流动规律设定好预设监测时间段，在歇业时间/下班时间内开启监测功能，即执行上述方法将大部分空闲RRU下电以节能。
进一步地，监测每个上电状态RRU下是否接入有终端，可以通过判断每个上电状态RRU下是否有新的终端接入来确定是否接入有终端，和/或，通过判断每个上电状态RRU是否与终端有交互数据流来确定是否有终端。
开启监测时BBU可以先获知RRU下是否接入有终端，如果某个RRU下本来接入有终端，那么可以看是否与终端交互数据，如果没有，可能这个终端退出接入；如果某个RRU下本来就没有终端接入，那么监测是否有新的终端接入，如果没有，说明一直空闲。
确定预设监测范围内在预设时长中无接入终端的上电状态RRU，可以是：
确定预设时长中没有与终端交互数据、并且没有新的终端接入的上电状态RRU。
需要说明的是，本申请所适用的场景下，可以不以每个RRU为一个小区，而是一个物理小区下包括多个RRU，一个逻辑小区下包括多个物理小区。具体地，逻辑小区可以指一个小区资源，拥有全球统一的小区标识，以及小区相关属性，如：频点、带宽、物理小区标识、发射功率等参数。逻辑小区的覆盖范围可以是单面天线覆盖范围，也可以是多面天线覆盖范围。物理小区可以指一个实际覆盖范围，这个覆盖范围内的各个天线点之间是射频合路。
若预设监测范围内存在逻辑小区的所有RRU全部下电，停止监测该逻辑小区中RRU下是否接入有终端。
具体实现时，监测预设监测范围内每个上电状态RRU下是否接入有终端，可以是实时监测每个逻辑小区内每个物理小区下接入的终端、以及业务流，如果预设时长内，某个物理小区下无接入终端也无业务流，则直接将这 个物理小区下除预设常开RRU之外的所有RRU下电。如果这个物理小区内没有预设常开RRU，在这个物理小区下所有RRU都下电后可以不再监测该物理小区。同理，如果某个逻辑小区下所有RRU都下电，也可以不再监测该逻辑小区，直到后续有终端再接入后，触发该逻辑小区下一个或多个RRU上电后，再重新进行监测。
另外，预设监测时间段内，将部分RRU下电节能后，还可以根据用户需要再将这些被下电的RRU上电。例如某个写字楼晚上开启监测后，大部分RRU被下电，但是突然有用户回到写字楼加班，那么可以根据该用户的需求再将部分RRU上电。
可选地，监测到新的终端接入预设常开RRU，根据预设RRU拓扑获取该预设常开RRU的至少1个相邻RRU；将该至少1个相邻RRU中处于下电的RRU上电。
某个终端接入某个预设常开RRU后，为了更好地为该用户服务，将该预设常开RRU的至少1个相邻RRU上电，该终端可能会发生移动，这些RRU上电后都会继续被监测，进而，监测上电后的其他RRU有新的终端接入后，也根据预设RRU拓扑上电有终端接入的RRU的相邻RRU，依次类推，将用户需要的RRU上电。由于处于预设监测时间段，空闲的RRU也会及时被下电，实现在用户较少的情况下根据终端的接入灵活调整RRU的上下电，以便于节能的同时也不耽误为用户服务。
上述预设RRU拓扑用于标识预设监测范围内RRU之间的相邻关系。
需要说明的是，根据监测情况将用户需要的RRU上电也可以是独立的实施例。
具体地，监测过程中，有终端接入了RRU，根据预设拓扑获取该RRU的至少1个相邻RRU；将这至少1个相邻RRU中处于下电状态的RRU全部上电。即监测到某个上电状态下的RRU有新的终端接入了，那么就将该RRU相邻的所有RRU都上电，以便于终端发生移动时，及时为终端提供服务，实现了可以根据灵活的监测在用户需要时将所需的RRU上电，为用户提供服务，在节能的同时也保证了用户的服务不受影响。
其他实施方式都于前述实施例类似，在此不再赘述。
可选地，预设RRU拓扑可以预先由人工根据RRU实际部署的位置坐标 进行建立，并将建立好的预设RRU拓扑存入BBU。
也可以由BBU自己根据信号质量参数建立预设RRU拓扑。
图3为本申请提供的另一种射频拉远单元的控制方法流程示意图，如图3所示，BBU建立预设RRU拓扑可以包括如下过程：
S301、获取预设监测范围内各RRU转发的终端信号测量信息。
该信号质量信息可以包括：终端的标识、以及由终端测量的信号质量参数。
可选地，BBU可以在预设统计时间段内，通过RRU向接入的终端指示测量信号质量参数，各RRU下接入的终端就会根据接收到的RRU发送的信号测量获取信号质量参数，并将信号质量参数发送给RRU，RRU再将信号质量参数转发给BBU，具体地，终端可以以向RRU发送数据包，数据包中携带信号质量参数，RRU不解析该数据包，BBU收到后确定那个RRU发来的数据包，然后解码获取里面的信道质量参数。
S302、根据终端信号测量信息，确定预设监测范围内每个RRU相邻的至少1个RRU。
具体地，可以根据各RRU转发的终端信号测量信息，依次确定每两个RRU之间的相邻关系。一般相邻两个RRU获取到的同一终端上报的信号质量参数差值在一定范围内。
信号质量参数可以是参考信号接收功率(Reference Signal Receiving Power，简称RSRP)，即终端根据RRU发送的参考信号进行测量，获取的RSRP。
终端会周期性地向RRU发送信号质量参数，RRU也可以周期性地将终端上报的RSRP转发给BBU，BBU统计预设统计时间段(例如一天时间)内RRU上报的RSRP，以确定RRU的相邻关系。
具体地，可以依次轮询每两个RRU是否相邻，以任意两个RRUx和RRUy为例，获取至少1个相同终端上报的针对RRUx和RRUy的信号质量参数，并统计次数，例如有3个终端都上报过RRUx和RRUy的信号质量参数，总共报了50次，那么就求这50次信号质量参数之间差值的平均值。
可选地，以信号质量参数为RSRP为例，采用公式：
Figure PCTCN2016108164-appb-000001
计算RRUx和RRUy的信号质量参数差值Avg-xy，其中，n为相同终端上报的针对RRUx和RRUy的信号质量参数总次数，n为大于0的整数，RSRPxi为第i次上报的RRUx的RSRP，RSRPyi为第i次上报的RRUy的RSRP，RSRPxi和RSRPyi是同一终端上报的。
若Avg-xy满足预设条件，则认为RRUx和RRUy相邻，否则不相邻。
S303、根据预设监测范围内每个RRU相邻的至少1个RRU，建立预设RRU拓扑。
可选地，以BBU下包括N个RRU为例，N为大于0的整数，可以如表1所示，“1”表示两个RRU相邻，“0”表示两个RRU不相邻，在此不作限制。
表1
  RRU1 RRU2 RRU3 … RRUN
RRU1 - 1 0 … 1
RRU2 1 - 0 … 1
… …. …. …. … ….
RRUN 0 1 1 … ….
进一步地，可以在预设监测时间段结束时，将预设监测范围内处于下电状态的RRU全部上电。
即根据预设监测时间段，在监测结束时BBU恢复预设监测范围内所有RRU上电。以写字楼为例，可以预设晚上10点到早上6点为预设监测时间段，那么在早上6点结束监测时将写字楼内所有RRU上电，以便于在上班时间段为用户提供更好地服务。
