背景技术
随着大规模有源天线整列的逐步应用以及第五代(5 th generation，5G)移动网络的大规模地建设，无线通信网络的能耗大幅增加，能耗成本增速甚至超过了运营商的收入增长。
因此，需要进行网络的节能管理，以获得网络节能效果，从而获得网络收益。而进行网络节能管理，可能会对网络性能造成一定的损失，例如网络时延加大、用户体验降低。目前的网络节能管理方法，虽然刚开始可能达到预期的要求，但随着时间的推移、网络运行情况的变化，要么逐渐出现节能“过度”的现象，即网络性能损失超过预期；要么逐渐出现节能“不到位”的现象，即网络节能效果低于预期。因此，如何有效地进行网络节能管理，使网络节能效果与网络性能损失持续满足既定的要求，是本申请需要解决的问题。

具体实施方式
下面结合本申请实施例中的附图对本申请实施例进行描述。
图1为本申请实施例提供的一种网络节能管理系统的架构示意图，该网络节能管理系统包括第一网络管理单元101(可以有更多，图中未示出)、第二网络管理单元102(可以有更多，图中未示出)、以及由第二网络管理单元102管理的网络节点集合103(图中示出该网络节点集合103包括n个网络节点)。其中，第一网络管理单元101的功能可以部署在独立的设备/装置上，也可以部署在具备其他功能的设备/装置上；部署了第一网络管理单元101的功能的设备/装置称为第一网络管理设备/第一网络管理装置；为叙述方便，本申请实施例中第一网络管理单元、第一网络管理装置或第一网络管理设备统一用第一网络管理单元指代。同样地，第二网络管理单元102的功能可以部署在独立的设备/装置上，也可以部署在具备其他功能的设备/装置上；部署了第二网络管理单元102的功能的设备/装置称为第二网络管理设备/第二网络管理装置，第二网络管理单元、第二网络管理装置或第二网络管理设备统一用第二网络管理单元指代。在一种可能的方案中，第一网络管理单元可以是网络管理系统(network management system，NMS)、跨域网络管理单元、或业务支撑系统(business support system，BSS)。第二网络管理单元可以是网元管理系统(element management system，EMS)、或域管理单元。
网络节点可以是网元或网元中负责某个网络功能的模块；其中，网元可以是核心网网元，也可以是无线网络网元；核心网网元包括但不限于：移动交换中心(mobile switching center，MSC)、关口移动交换中心(gateway mobile switching center，GMSC)、GPRS(general packet radio service，通用分组无线业务)业务支撑节点(serving GPRS support node，SGSN)、网关GPRS支撑节点(gateway GPRS support node，GGSN)、移动性管理实体(mobility management entity，MME)、服务网关(serving gateway，SGW)、分组网关(packet gateway，PGW)、接入管理功能(access management function，AMF)设备、用户面功能(user plane function，UPF)设备、会话管理功能(session management function，SMF)设备；无线网络网元包括但不限于基站和基站控制器，基站可以是：全球移动通信系统(global system for mobile communications，GSM)基站、通用移动通信系统(universal mobile telecommunications system，UMTS)基站、长期演进(long term evolution，LTE)基站、新空口(new radio，NR)基站，其中，LTE基站也称为演进型基站(evolved NodeB，eNB)，新空口基站也称为5G基站(gNodeB，gNB)；基站控制器可以是GSM基站控制器、UMTS基站控制器。
在该网络节能管理系统中，第一网络管理单元确定网络节能范围信息和第一网络节能模式，并向第二网络管理单元发送第一节能控制消息，该第一节能控制消息包括网络节能范围信息和第一网络节能模式。其中：
网络节能范围信息用于确定目标网络节点集合，该集合包含一个或多个将进行节能操作的网络节点。如图1中，假设第一网络管理单元101确定对网络节点集合103进行节能控制，则网络节点集合103作为目标网络节点集合。进一步地，第一网络管理单元101也可以对网络节点集合103中的部分网络节点进行节能控制。
第一网络节能模式用于表示对目标网络节点集合的网络节能效果与网络性能损失的第一要求。示例性地，该要求可以包括网络节能效果的取值范围(如取值下限)及相应网络性能损失的取值范围(如取值上限)，也可以包括网络性能损失与相应网络节能效果之间的比值的取值范围(如取值上限)，或者网络节能效果与网络性能损失之间的比值的取值范围(如取值 下限)。
网络节能效果为目标网络节点集合的节能效果，用于表征对目标网络节点集合进行节能控制后的特定时间段内在能源上的节约程度；网络节能效果可以用节约能量的相对值来表示：例如，假设特定时间段为[t1,t2]，在没有节能控制的情况下目标网络节点集合在时间段[t1,t2]的能耗为Eo，而在有节能控制的情况下目标网络节点集合在时间段[t1,t2]的能耗为En，则网络节能效果可以表示为(Eo-En)/Eo*100％；网络节能效果也可以用其他方式表示，例如，可以用节约能量的绝对值(如Eo-En，即节约的度数)表示，对此，本申请实施例不作限定；下文将用节约能量的相对值表示网络节能效果，且为叙述方便，有时候也将网络节能效果简称为节能效果。
节能控制往往会影响目标网络节点集合所支撑的网络业务的性能，造成网络性能损失。
网络性能损失为目标网络节点集合的性能损失，用于表征对目标网络节点集合进行节能控制后的特定时间段内在网络业务的性能指标上的降低程度或恶化程度；网络性能损失可以用性能损失的相对值来表示：例如，假设特定时间段为[t1,t2]，在假设没有进行节能控制情况下目标网络节点集合在时间段[t1,t2]的性能指标值为Po，而在有节能控制的情况下目标网络节点集合在时间段[t1,t2]的性能指标值Pn，则网络性能损失可以表示为(Po-Pn)/Po*100％；网络性能损失也可以用其他方式表示，例如，可以用性能损失的绝对值(如Po-Pn)表示，对此，本申请实施例不作限定；下文将用性能损失的相对值表示网络性能损失，且为方便叙述，有时候也将网络性能损失简称为性能损失。网络业务的性能指标简称为网络性能指标。网络性能指标包括但不限于数据流量、吞吐率、语音话务量、接入成功率、掉话率、切换成功率、信号覆盖率等。网络性能损失可以采用前述多种网络性能指标中的任一种指标来表征，也可以采用多种网络性能指标的组合来表征，例如，网络性能损失Δp＝f(k*ΔTRF,m*ΔTRP,n*ΔBPM)，TRF表示网络流量，ΔTRF表示网络流量损失，ΔTRF＝(TRFo-TRFn)/TRFo*100％，TRFo表示假设没有进行节能控制情况下目标网络节点集合在[t1,t2]时间段的网络流量，TRFn表示在有节能控制的情况下目标网络节点集合在[t1,t2]时间段的网络流量；TRP表示吞吐率，ΔTRP表示吞吐率损失，ΔTRP＝(TRPo-TRPn)/TRPo*100％，TRPo表示假设没有进行节能控制情况下目标网络节点集合在[t1,t2]时间段的吞吐率，TRPn表示在有节能控制的情况下目标网络节点集合在[t1,t2]时间段的吞吐率；BPM表示基础关键性能指标(key performance indicator，KPI)，ΔBPM表示基础关键性能指标损失，ΔBPM＝(BPMo-BPMn)/BPMo*100％，BPMo表示假设没有进行节能控制情况下目标网络节点集合在[t1,t2]时间段的KPI，BPMn表示在有节能控制的情况下目标网络节点集合在[t1,t2]时间段的KPI，基础KPI包括但不限于接入成功率、掉话率、切换成功率等指标。k、m、n表示相应的指标的权重值，取值范围均为[0-,1]，当取0时表示不包含相应的指标。上述节能前后的流量、用户吞吐率、基础KPI指标可以通过话统或历史话单/测量报告(call history record/measurement report，CHR/MR)等数据汇总统计获取。
上述特定时间段，可以由工作人员事先在第一网络管理单元和/或第二网络管理单元上预设，也可以由第一网络管理单元和/或第二网络管理单元根据能耗变化周期或性能变化周期确定。
网络节能模式反映第一网络管理单元在网络节能效果与网络性能损失之间的取舍策略或平衡策略，也反映第一网络管理单元的在节能的管理和控制上的意图，因此，网络节能模式也可以称为节能管控意图、节能管控需求、节能需求等。例如，该第一网络管理单元是运营 商级别的网络管理单元，则该第一网络节能模式或该节能管控意图反映了运营商的商业意图、业务意图或网络意图。
第二网络管理单元根据第一节能控制消息使目标网络节点集合进行节能操作，以使目标网络节点集合的网络节能效果与网络性能损失满足第一网络节能模式。
具体地，第二网络管理单元根据第一节能控制消息使目标网络节点集合进行节能操作，是指第二网络管理单元直接地(参见图2对应实施例)或间接地(参见图3对应实施例)向目标网络节点集合中的网络节点发送网络配置指令(针对不同网络节点可以发送相同的网络配置指令，也可以发送不同的网络配置指令)，以使目标网络节点集合以整体上节约能量的工作状态运行(以支撑网络业务)，或者停止运行。应理解，目标网络节点集合中可以不必每一个网络节点都处于节约能量的工作状态，整体上处于节约能量的状态即可。上述网络配置指令可以包括网络配置参数。目标网络节点集合中的网络节点接收并执行网络配置指令，相应网络节点根据网络配置指令中的网络配置参数配置运行、停止运行或停止相应部分功能模块的运行，以节约能量。
如图2所示，为本申请实施例提供的又一种网络节能管理系统的架构示意图，其中，跨域网络管理单元201(例如运营商级别的网络管理单元)为图1的第一网络管理单元，域网络管理单元202(例如运营商下属单位级别的网络管理单元)为图1的第二网络管理单元。跨域网络管理单元201对域网络管理单元202(可以为多个，图中仅示出了一个域网络管理单元)进行管理。域网络管理单元202管理网络节点集合203(图中示出了网络节点集合203包括m个网络节点，假设跨域网络管理单元201确定网络节点集合203进行节能控制，则网络节点集合203作为目标网络节点集合)。在进行网络节能管理过程中，跨域网络管理单元201确定第一网络节能模式和网络节能范围信息，向域网络管理单元202发送第一节能控制消息，域网络管理单元202根据第一节能控制消息向目标网络节点集合203中的网络节点发送网络配置指令。
如图3所示，为本申请实施例提供的又一种网络节能管理系统的架构示意图，BSS 301为图1的第一网络管理单元，跨域网络管理单元302为图1的第二网络管理单元。跨域网络管理单元302可以管理一个或多个域网络管理单元303(图中示出了一个域网络管理单元303)，域网络管理单元303又对与之连接的网络节点集合304进行管理(图中示出了网络节点集合304包括t个网络节点，BSS 301确定对该网络节点集合304进行节能控制，则该网络节点集合304作为目标网络节点集合)。在进行网络节能管理过程中，BSS 301确定第一网络节能模式和网络节能范围信息，向跨域网络管理单元302发送第一节能控制消息，跨域网络管理单元302根据第一节能控制消息使目标网络节点集合进行节能操作包括以下几种实现方式：
实现方式一：跨域网络管理单元302根据第一节能控制消息和目标网络节点集合的业务场景信息，确定网络配置参数，并向目标网络节点集合304发送网络配置指令，该网络配置指令包括上述网络配置参数。
实现方式二：跨域网络管理单元302根据第一节能控制消息和目标网络节点集合的业务场景信息，确定网络配置参数，并向域网络管理单元303发送网络配置指令，域网络管理单元303透传或转发该网络配置指令给目标网络节点集合304；
实现方式三：跨域网络管理单元302向域网络管理单元303转发第一节能控制消息，由域网络管理单元303根据该第一节能控制消息和目标网络节点集合的业务场景信息，确定网 络配置参数，并发送该网络配置指令给目标网络节点集合304。
在上述多种实现方式中，跨域网络管理单元302/域网络管理单元303向目标网络节点集合304发送网络配置指令，以使目标网络节点集合以整体上节约能量的工作状态运行(以支撑网络业务)，或者停止运行。
下面结合图1～图3所示的系统架构，详细描述网络节能管理过程：
如图4所示，为本申请实施例提供的一种网络节能管理方法的流程示意图，该方法可以包括以下步骤：
S141、第一网络管理单元确定网络节能范围信息和第一网络节能模式。
一般地，第一网络管理单元，例如运营商级别的网络管理单元，往往对一个较大的区域内的网络节点集合进行管理。而为了提高网络节能管理的针对性或者为了实现“精准”节能，第一网络管理单元可以针对其所管理的网络节点中的部分网络节点进行网络节能管理。为此，第一网络管理单元还可以确定网络节能范围信息，该网络节能范围信息可以用于确定目标网络节点集合，该目标网络节点集合包含一个或多个将进行节能操作的网络节点。
在一个实现方式中，网络节能范围信息包括一个或多个将进行节能操作的网络节点的标识。第二网络管理单元可以直接根据该一个或多个将进行节能操作的网络节点的标识确定目标网络节点集合，该目标网络节点集合包括该一个或多个标识对应的网络节点。网络节点的标识可以用网络节点的IP地址，或者IP地址和端口号，MAC地址等表示，本申请实施例不限定网络节点的标识的表示方式。
在另一个实现方式中，网络节能范围信息可以包括以下任意一项或多项，作为第二网络管理单元确定目标网络节点集合的“过滤条件”：
将进行节能操作的网络节点的地理位置；
将进行节能操作的网络节点的网络制式；
将进行节能操作的网络节点所支撑的网络业务。
其中，将进行节能操作的网络节点的地理位置可以是用具体的经纬度范围表示的区域，还可以是某个预先划分好的行政区/社区/街道等。例如，第一网络管理单元确定将进行节能操作的网络节点的地理位置为纬度23°～25°、经度18°～20°对应的地理范围，则确定目标网络节点集合包括该地理范围内的网络节点。再如，第一网络管理单元确定将进行节能操作的网络节点的地理位置为海淀区，则确定目标网络节点集合包括海淀区内的网络节点。
其中，如果目标网络节点集合中的网络节点是无线接入设备，则将进行节能操作的网络节点的网络制式是指参与节能的目标网络节点集合的无线网络制式。例如现网中有GSM、LTE和NR三个制式的网络，第一网络管理单元确定目标网络节点集合的网络制式为LTE、NR，则确定目标网络节点集合包括采用LTE或NR的网络节点。
其中，将进行节能操作的网络节点所支撑的网络业务包括但不限于：移动宽带(mobile broadband，MBB)业务、面向企业客户(to business，2B)业务(如抄表业务、城市监控视频回传业务、工业园区智能制造业务、智能港口业务等)或车联网(internet of vehicles，IoV)业务等。因此，这里目标网络业务也是业务类型的意思。支撑网络业务的网络节点是指可以承载网络业务的数据流的网络节点。若实现无线管控融合或者无线网管设备同时管控核心网，则第一网络管理单元可以识别网络节点所支撑的网络业务，例如，第一网络管理单元确定将进行节能操作的网络节点所支撑的网络业务为抄表业务，则可以确定目标网络节点集合包括支撑抄表业务的网络节点；或者，第一网络管理单元为无线切片管理器，则其可以根据单一 网络切片选择辅助信息(single-network slice selection assistance information，S-NSSAI)(又称为网络切片标识)识别网络节点所支撑的垂直行业的网络业务，从而第一网络管理单元确定某个网络切片标识，则可以确定目标网络节点集合包括该网络切片标识所标识的网络切片内的网络节点。
本实施例中涉及多种网络节能模式，第一网络管理单元可以在多种网络节能模式中确定一种网络节能模式作为第一网络节能模式。
示例性地，该网络节能模式可分为以下几种：
1)不节能模式：表示不要求目标网络节点集合以节约能量的工作状态运行(自然也不会引起网络性能损失)。具体地，网络节能效果X＝0％、网络性能损失Y＝0％。
2)性能无损网络节能模式：表示要求目标网络节点集合以节约能量的工作状态运行，但不能有网络性能损失。
3)性能有损网络节能模式：表示要求目标网络节点集合以节约能量的工作状态运行，允许有一定的网络性能损失。具体地，性能有损网络节能模式又可以有如下形式：
3.1)性能损失设限模式：表示要求目标网络节点集合以节约能量的工作状态运行，但确保网络性能损失不高于一个门槛值b％，至于网络节能效果不加限定；根据b％的大小，可以分为性能微损模式、性能中度有损模式、性能重度有损模式等。
3.2)性价比设限模式：表示要求目标网络节点集合以节约能量的工作状态运行，但确保网络节能效果与网络性能损失的比值不低于门槛值p。
4)完全网络节能模式：表示要求目标网络节点集合关闭或者停止运行，不产生能耗。
第一网络管理单元可以从上述示例的多种网络节能模式中确定一种网络节能模式，作为第一网络节能模式。示例性地，第一网络管理单元可以根据网络业务的属性或者本地预设的配置数据，确定第一网络节能模式。其中，网络业务的属性包括优先级、业务类型等。例如，第一网络管理单元可以根据网络业务的优先级确定第一网络节能模式：针对优先级高的网络业务对应的目标网络节点集合，选用不节能模式；针对优先级中的网络业务对应的目标网络节点集合，选用性能微损模式；针对优先级低的网络业务对应的目标网络节点集合，选用性能重度有损模式；再如，第一网络管理单元也可以根据网络业务的类型确定第一网络节能模式，对于抄表业务对应的目标网络节点集合，选用性能重度有损模式；对于城市监控视频回传业务对应的目标网络节点集合，选用性能微损模式；对于极可靠低时延通信(ultra-reliable and low latency communication，URLLC)业务对应的目标网络节点集合，选用不节能模式。第一网络管理单元也可以本地预先配置网络业务与网络节能模式的对应关系，例如，配置抄表业务对应性能重度有损模式，配置城市监控视频回传业务对应性能微损模式，配置URLLC业务对应不节能模式，则第一网络管理单元在进行网络节能管理之前，可以识别某个网络节能范围内的目标网络节点集合当前进行的网络业务，然后，根据本地预设的配置数据，确定与该网络业务对应的网络节能模式。
S142、第一网络管理单元向第二网络管理单元发送第一节能控制消息。相应地，第二网络管理单元接收该第一节能控制消息。
第一网络管理单元在确定第一网络节能模式和网络节能范围信息后，生成第一节能控制消息，其中包括上述网络节能范围信息和第一网络节能模式。
第一网络管理单元向第二网络管理单元下发第一节能控制消息，以使第二网络管理单元可以根据该第一节能控制消息使目标网络节点集合进行节能操作，使目标网络节点集合的网 络节能效果与网络性能损失满足第一网络节能模式。例如，该第一网络管理单元是运营商级别的网络管理单元，则第一网络管理单元发送第一节能控制消息，以期满足运营商的商业意图、业务意图或网络意图。
在一种可能的实现方案中，节能控制消息中的网络节能模式可以显式包含第一网络管理单元对目标网络集合的网络节能效果和网络性能损失的要求。以下为示例性的节能控制消息及包含的网络节能模式。
Figure PCTCN2021109993-appb-000001
可选地，上面EnergySaveMode中还可以包含时间段，表示在该时间段内计算节能效果和性能损失，示例如下：
Figure PCTCN2021109993-appb-000002
Figure PCTCN2021109993-appb-000003
在一种可能的实现方案中，可以在第一网络管理单元、第二网络管理单元、目标网络节点集合的网络管理单元中预设一些网络节能模式，并为这些网络节能模式设置唯一标识，则节能控制消息可以包含网络节能模式的唯一标识，示例性的节能控制消息如下：
EnergySaveControlRequest{
"EnergySaveModeId":"ASDF1234"//网络节能模式标识
}
应理解，在一种可能的方案中，第一节能控制消息也可以不包含网络节能范围信息，这表示第一网络管理单元指示对其管辖范围内的所有网络节点进行节能控制。例如，第一网络管理单元为NMS，第二网络管理单元为网元管理系统(element management system，EMS)，NMS对一个或多个EMS进行管理，每个EMS又对一个较小范围内的网络设备(network equipment，NE)进行管理，此时，NMS可以不确定网络节能范围信息，而对其管理的所有NE进行节能控制。
应理解，在一种可能的方案中，第一网络管理单元也可以从其他的第一网络管理单元接收第一节能控制消息，而不是自身生成第一节能控制消息。
S143、第二网络管理单元根据第一节能控制消息触发目标网络节点集合进行节能操作，以使目标网络节点集合的网络节能效果和网络性能损失满足第一网络节能模式。
第二网络管理单元接收到第一网络管理单元发送的第一节能控制消息后，根据第一节能控制消息中的网络节能范围信息确定目标网络节点集合。
具体地，第二网络管理单元可以根据上述一项或多项网络节能范围信息确定目标网络节点集合。
例如，假设网络节点范围信息包括网络节点1～m的标识，则将网络节点1～m作为目标网络节点集合；
再如，假设网络节能范围信息包含的将进行节能操作的网络节点的地理位置为“纬度23°～25°、经度18°～20°”，则将位于纬度23°、经度18度地理范围内的网络节点作为目标网络节点集合。
再如，假设网络节能范围信息包含的将进行节能操作的网络节点的地理位置为“海淀区”，则将海淀区范围内的网络节点作为目标网络节点集合。
再如，网络节能范围信息包含的将进行节能操作的网络节点的网络制式包括LTE和NR，则将网络制式为LTE或NR的网络节点作为目标网络节点集合。
再如，网络节能范围信息包含的将进行节能操作的网络节点所支撑的网络业务为“抄表业务”，则将支撑抄表业务的网络节点作为目标网络节点集合。
再如，网络节能范围信息包含的将进行节能操作的网络节点所支撑的网络业务的切片标识为“S-NSSAI123”，则将S-NSSAI为“S-NSSAI123”的网络节点作为目标网络节点集合。
再如，网络节能范围信息包含的将进行节能操作的网络节点的地理位置为“海淀区”、且网络节能范围信息包含的将进行节能操作的网络节点的网络制式为“NR”，则将海淀区范围内的网络制式为“NR”的网络节点作为目标网络节点集合。
应理解，目标网络节点集合为第二网络管理单元可管理的网络节点，即可以直接或间接向其发送网络配置指令的网络节点，其中，所述间接向其发送网络配置指令是指第二网络管理单元通过另外一个设备向其发送网络配置指令，例如，向网络节点的管理单元发送网络配 置指令，再由网络节点的管理单元向网络节点发送网络配置指令。
第二网络管理单元根据第一节能控制消息触发目标网络节点集合进行节能操作，可以理解为第二网络管理单元根据第一节能控制消息使目标网络节点集合进行节能操作，或者，第二网络管理单元根据第一节能控制消息指示目标网络节点集合进行节能操作。具体地，第二网络管理单元在确定目标网络节点集合后，解析第一网络节能模式所表示的对目标网络节点集合的网络节能效果与网络性能损失的要求，并根据该要求使目标网络节点集合进行节能操作，以使目标网络节点集合的网络节能效果和网络性能损失满足第一网络节能模式。其中，节能操作是指目标网络节点集合的网络节点以节约能量的工作状态运行，甚至停止运行。
根据本申请实施例提供的一种网络节能管理方法，第一网络管理单元下发第一节能控制消息，第二网络管理单元根据第一节能控制消息使目标网络节点集合进行节能操作，可以使网络节能效果与网络性能损失持续满足既定的要求，有利于电信运营商从整体上平衡网络节能效果与网络性能损失之间的关系。
网络节点的业务场景信息可能发生变化，假如第二网络管理单元基于第一网络节能模式向目标网络节点下发固定的网络配置指令(包含网络配置参数)，则可能导致目标网络节点集合的网络节能效果和网络性能损失最终不能满足第一网络节能模式。例如，某个时间段，某个基站的业务场景是：网络负荷较低、用户数较少，那么，第二网络管理单元可以在发出的网络配置指令中包含的节能开关参数较多(如符号关断开关、载波关断开关等)、每个节能开关参数的取值也可以较大(如关断时段可以较长、触发载波关断的负载门限可以较高)。在另一个时间段，该基站的业务场景变为：用户数和负荷大幅升高，则如果该基站仍然开启载波关断，将导致部分用户设备无法接入或导致部分用户设备的吞吐率降低，造成网络业务性能损失，进而导致此前第一网络管理单元下发的网络节能模式(假设为“无损节能模式”)得不到满足。
此外，目标网络节点集合有时候也可能无法满足第一网络管理单元确定的网络节能模式，第一网络管理单元向第二网络管理单元下发固定的网络节能模式，最终可能不能满足运营商对节能的整体需求。
为此，本申请提供又一种网络节能管理方法，第二网络管理单元在接收到第一网络管理单元发送的第一节能控制消息后，可以基于第一网络节能模式和网络节点的业务场景的不同下发不同的网络配置参数，第一网络管理单元还可以根据第二网络管理单元反馈的节能控制结果，调整下发给第二网络管理单元的网络节能模式，使得目标网络节点集合的网络节能效果与网络性能损失尽可能满足下发的网络节能模式。
如图5所示，为本申请实施例提供的又一种网络节能管理方法的流程示意图，该方法可包括以下步骤：
S251、第二网络管理单元向第一网络管理单元发送节能控制能力信息，该节能控制能力信息包含第二网络管理单元支持的至少一个网络节能模式。相应地，第一网络管理单元接收该节能控制能力信息。
第一网络管理单元可以确定上述实施例中描述的任一种网络节能模式，然而，第二网络管理单元可能由于其网络拓扑、网络配置等因素导致并不能支持所有的网络节能模式。因此，第二网络管理单元向第一网络管理单元发送节能控制能力信息。该节能控制能力信息包含第二网络管理单元支持的至少一个网络节能模式。相应地，第一网络管理单元接收该节能控制能力信息。
S252、第一网络管理单元根据该节能控制能力信息，在第二网络管理单元支持的至少一个网络节能模式中选择一个网络节能模式作为第一网络节能模式；第一网络管理单元还确定网络节能范围信息。
第一网络管理单元接收到第二网络管理单元上报的其支持的至少一个网络节能模式后，可以在第二网络管理单元所支持的至少一个节能模式中选择一个网络节能模式，作为第一网络节能模式。例如，第二网络管理单元上报其支持性能无损网络节能模式和性能有损网络节能模式，而第一网络管理单元本身期望的网络节能模式是性能有损网络节能模式，则第一网管理单元可以确定性能有损网络节能模式，该网络节能模式也是第二网络管理单元所支持的网络节能模式。
进一步地，第一网络管理单元还确定网络节能范围信息。第一网络管理单元确定网络节能范围信息的方式可参考图4所示实施例的步骤S141的相关描述。
可以理解的是，第一网络管理单元也可以根据本地预设的配置数据确定网络节能模式，因而，第一网络管理单元可以不执行上述步骤S251和S252。
S253、第一网络管理单元向第二网络管理单元发送第一节能控制消息。相应地，第二网络管理单元接收该第一节能控制消息。
该步骤的具体实现可参考图4所示实施例的步骤S142。
此后，为使目标网络节点集合的整体网络节能效果和/或整体网络性能损失满足第一网络节能模式，第二网络管理单元对目标网络节点集合中的每一个网络节点进行节能控制，包括：基于业务场景信息和第一网络节能模式判断是否向该网络节点发送网络配置指令，如果发送网络配置指令，进一步确定发送的网络配置参数。
以目标网络节点集合中的任一网络节点(如网络节点A)为例，第二网络管理单元对其进行节能控制的示例性过程为S254-S257或者S254-S261的过程。
S254、第二网络管理单元获取网络节点A的第一业务场景信息。
网络节点A的业务场景信息与网络节点A的网络业务数据关联，第二网络管理单元可以根据网络节点的网络业务数据，获取网络节点的业务场景信息。
具体地，网络节点A向第二网络管理单元或网络节点A的管理单元发送第一网络业务数据。相应地，第二网络管理单元接收网络节点A的第一网络业务数据。
在一个实现方式中，第二网络管理单元可以周期性指示网络节点A上报其网络业务数据，或周期性指示网络节点A的管理单元上报其管理的网络节点A的网络业务数据；其中，第二网络管理单元可以向网络节点A发送订阅请求消息，以指示网络节点A上报网络业务数据，上报的周期可以是在网络节点A中预先设置的，也可以是第二网络管理单元通过订阅请求消息指定的。在又一个实现方式中，网络节点A可以在检测到其网络业务数据发生变化时，主动向其管理单元或第二网络管理单元发送网络节点A的网络业务数据。
其中，第一网络业务数据包括但不限于以下数据：
1)网络配置数据，其包括网络节点的网络制式、网络节点的邻区关系、网络配置参数、频点、带宽等；
2)网络拓扑数据，其包括网络连接关系、工程参数信息(包括网络节点位置、天线机械角等)。其中，第二网络管理单元可以从目标网络节点集合采集工程参数信息，也可以由外部提前导入工程参数信息；
3)网络性能数据，其包括能耗、负载、话务、吞吐率、接入成功率、掉话率、切换成功 率、覆盖率等。
第二网络管理单元在从网络节点A或网络节点A的管理单元接收到上述第一网络业务数据后，根据第一网络业务数据，获取第一业务场景信息。具体地，第二网络管理单元首先对第一网络业务数据进行预处理，包括对网络配置数据、网络拓扑数据、网络性能数据进行解析、关联、异常数据剔除等。然后，第二网络管理单元从预处理后的第一网络业务数据中提取与节能操作相关的网络场景特征，包括但不限于网络制式、话务特征等。然后，根据提取出的第一网络业务数据的网络场景特征，识别该网络节点的第一业务场景信息。例如，识别出的第一业务场景信息可以是“GSM单制式高话务负载场景”、“GSM/LTE多制式多频共模低话务负载场景”等。
基于获取的第一业务场景信息，第二网络管理单元可能确定不向网络节点A发送用于使其进行节能操作的网络配置指令。例如，根据第一业务场景信息，第二网络管理单元确定网络节点A此时话务量较大(例如超过某个预设的门限)，如果进一步节能将过分损害网络性能，因此确定不发送用于使网络节点A进行节能操作的网络配置指令，则不执行S255及之后的步骤。以下假设第二网络管理单元确定向网络节点A发送网络配置指令。
S255、第二网络管理单元基于第一网络节能模式和第一业务场景信息确定第一网络配置参数，第一网络配置参数用于使网络节点A以节约能量的工作状态运行。
本实施例中，网络节能模式、业务场景信息与网络配置参数之间具有关联关系，该关联关系可以是某种函数关系、表格关系或曲线图关系等。该关联关系可以通过神经网络模型训练得到。
可以理解的是，存在多种网络节能模式，业务场景信息也包括多维度的信息，网络配置参数也包括多个，该关联关系是指多种网络节能模式与多维度的业务场景信息、多个网络配置参数之间的关系。不同的网络节能模式或不同的业务场景信息可以关联到相同的网络配置参数，相同的网络节能模式或相同的业务场景信息也可以关联到不同的网络配置参数，相同的网络节能模式可以关联到不同的业务场景信息。
第二网络管理单元可以根据网络节能模式和业务场景信息确定网络配置参数。具体地，在本实施例中，第二网络管理单元可以根据第一网络节能模式和目标网络节点集合的第一业务场景信息确定第一网络配置参数。
其中，网络配置参数包括：节能开关参数、关断时段和关断门限等。
其中，节能开关参数又可以包括：
a1)符号关断开关：当该开关打开时，表示网络节点在没有数据发送的符号周期内关闭功放，从而降低系统功耗。
a2)射频通道关断开关：当该开关打开时，表示在预设的时间内及负载条件下关闭部分射频通道，从而降低系统功耗。
a3)载波关断开关：在网络闲时、业务非常少的情况下，关闭同覆盖区域的其中一个或多个载波以降低网络节点的功耗。
a4)网络节点发射功率：通过降低网络节点发射功率，降低系统功耗。
关断时段又可以包括：
b1)射频通道关断起始时间和停止时间：表示射频通道关闭的起始时间和停止时间。
b2)载波关断起始时间和停止时间：表示载波关闭的起始时间和停止时间。
关断门限又可以包括：
c1)射频通道关断上行PRB利用率门限、下行PRB利用率门限：表示当网络节点的上行、下行PRB利用率低于该门限时，触发射频通道关断，即关闭部分射频通道。
c2)射频通道关断用户数门限：表示当网络节点内的用户数低于该门限时，触发射频通道关断，即关闭部分射频通道。
c3)载波关断上行PRB利用率门限、下行PRB利用率门限：表示当载波的上行、下行PRB利用率低于该门限时，触发载波关断，即关闭该载波。
c4)载波关断用户数门限：表示当载波内的用户数低于该门限时，触发载波关断，即关闭该载波。
下面示例性地描述了业务场景信息与网络配置参数之间的关联关系、以及网络节能模式与网络配置参数之间的关联关系如下：
业务场景信息与网络配置参数的关系
a)第二网络管理单元根据网络节点的业务场景信息(例如，话务负载的高低)，确定网络配置参数(例如，确定是否降低基站发射功率，以及是否开启符号关断、射频通道关断或载波关断，并设置相应的关断起始时间、停止时间、上行PRB利用率门限、下行PRB利用率门限、用户数门限等)。其中，话务负载低的小区或时段，表示话务量低或用户数少(如平均用户数小于1)，则可以符号关断、射频通道关断和载波关断均可开启，相应的关断时段可设置得更长(具体关断时段与话务量低或用户数少的时间段相关)，关断门限可设置得更高(例如PRB利用率门限可设置为25～35％，仅供示例，也可以更高或更低一些)。这样带来的网络节能效果较高。话务负载高的业务场景，则反之，例如仅开启符号关断，这样带来的网络节能效果较低。
b)第二网络管理单元根据网络节点的业务场景信息(例如，无线网络制式和每种制式频点的数量)，确定网络配置参数(例如，确定是否将话务或用户迁移到其中某个网络制式或某个频点下，以降低甚至清空其他网络制式或频点的话务，并将低话务或无话务载波的射频通道关断或载波关断的关断时段时长提高、关断门限提高)，从而带来更高的网络节能效果预期。
网络节能模式与网络配置参数的关系
第二网络管理单元根据网络节能模式，确定网络配置参数，例如，确定是否降低基站发射功率，以及是否开启符号关断、射频通道关断或载波关断，并设置相应的关断起始时间、停止时间、上行PRB利用率门限、下行PRB利用率门限、用户数门限等。在相同业务场景信息下，若网络节能模式所允许的网络性能损失越高，则可以打开的节能开关参数越多；相应地，关断时段可设置得更长，关断门限可设置得更高，这样带来的网络节能效果较高。反之亦然。
例如，在LTE多载波高话务负载场景下，
a)当确定性能无损网络节能模式时，仅开启符号关断，网络节能效果可能仅有3～5％(仅为示例数据，可能更低或更高)；
b)当确定性能中度有损模式时，可同时开启符号关断、射频通道关断和载波关断，PRB利用率门限可设置为10～20％(仅供示例，可能更高或更低)，用户数门限可设置为2～3(仅供示例，可能更高或更低)，相应的关断时段可选择一天内话务量最低的12个小时(仅供示例，可能更高或更低)。网络节能效果可能达到8～10％(仅供示例，可能更高或更低)，但网络性能损失可能也达到10～20％(仅供示例，可能更高或更低)。
可以看出，业务场景信息与网络配置参数、网络节能模式与网络配置参数两两之间具有关 联关系，从而通过神经网络模型等可以训练得到业务场景信息、网络节能模式与网络配置参数三者之间的关联关系。
第二网络管理单元可以预先存储业务场景信息、网络节能模式与网络配置参数的关联关系。上述预先存储的业务场景信息、网络节能模式与网络配置参数的关联关系可以通过以下方式获取：
1)第二网络管理单元预置上述关联关系模型：采用离线方式，第二网络管理单元或具备模型处理功能的离线平台通过对已有大量数据进行多维数学拟合或回归获得后，开发人员再通过版本升级的方式预置到在线的第二网络管理单元中。离线拟合或归回所需的输入数据包括但不限于网元场景、网络配置、网络拓扑、网络性能等数据。
2)第二网络管理单元在线学习方式获取：通过逐步递进加大节能强度的方式获取不同场景下性能损失、节能效果与网络配置参数(即网络配置参数值组合)之间的关系。
第二网络管理单元可以根据接收到的第一网络节能模式、第一业务场景信息以及预先存储的业务场景信息、网络节能模式与网络配置参数的关联关系确定第一网络配置参数。具体地，将接收到的第一网络节能模式、第一业务场景信息输入到神经网络模型，即可输出第一网络配置参数。
一个目标网络节点集合可以包括一个或多个网络节点，不同的网络节点的业务场景信息可能不同。以业务场景信息为话务负载特征为例，一个目标网络节点集合中，有的网络节点话务负载很高，例如，某些基站的话务负载高于第一值，该基站被认为是重度负荷基站；有的网络节点话务负载较高，例如，基站的话务负载低于第一值，且高于第二值，该基站被认为是中度负荷基站；有的网络节点话务负载较低，例如，基站的话务负载低于第二值，该基站被认为是低度负荷基站。针对一个目标网络节点集合中不同的业务场景信息对应的网络节点，可以配置不同的网络配置参数。例如，对于重度负荷基站，要提高基站发射功率，配置基站发射功率为A1；对于中度负荷基站，可以维持基站发射功率不变，例如，当前基站发射功率为A2；对于低度负荷基站，需要降低基站发射功率，配置基站发射功率为A3。提高基站发射功率，势必提高基站能耗；降低基站发射功率，可以降低基站能耗。然而，本实施例进行节能管理，只要目标网络节点集合的整体的网络节能效果和网络性能损失满足网络节能模式即可。因此，可以针对目标网络节点集合中网络节点的不同的业务场景信息，确定不同的网络配置参数。
S256、第二网络管理单元向网络节点A或网络节点A的管理单元发送第一网络配置指令，该第一网络配置指令包括第一网络配置参数。相应地，该网络节点或该网络节点的管理单元接收第一网络配置指令。
第二网络管理单元在确定第一网络配置参数后，向网络节点A或网络节点A的管理单元发送第一网络配置指令，该第一网络配置指令包括上述第一网络配置参数，该第一网络配置指令用于指示网络节点执行该第一网络配置参数。
在一个实现中，第二网络管理单元可以分别向目标网络节点集合中的每个网络节点或每个网络节点的管理单元发送第一网络配置指令。
在另一个实现中，第二网络管理单元也可以统一向目标网络节点集合中的所有网络节点或所有网络节点的管理单元发送第一网络配置指令。在上述实现中，每个网络节点对应的第一网络配置参数可以相同或不同，或者部分网络节点对应的第一网络配置参数相同。
可以理解的是，作为步骤S254～S256的一种替换方式，例如在图3所示的系统架构中， 第二网络管理单元(跨域网络管理单元302)在接收到第一节能控制消息后，可以向域网络管理单元303转发该第一节能控制消息；域网络管理单元303根据第一节能控制消息和目标网络节点集合304中的网络节点的业务场景信息，确定第一网络配置参数，并发送携带第一网络配置参数的第一网络配置指令给目标网络节点集合304中的网络节点。
可以理解的是，作为步骤S254～S256的又一种替换方式，例如在图3所示的系统架构中，第二网络管理单元(跨域网络管理单元302)在接收到第一节能控制消息后，确定第一网络配置参数，并向域网络管理单元303发送携带第一网络配置参数的第一网络配置指令；域网络管理单元303透传或转发该第一网络配置指令给目标网络节点集合304中的网络节点。
S257、网络节点A执行第一网络配置指令。
目标网络节点集合中的网络节点A在接收到第二网络管理单元或其管理单元发送的第一网络配置指令后，执行该第一网络配置指令。例如，该第一网络配置指令为调整目标网络节点集合中的网络节点A的节能开关参数，则目标网络节点集合中的网络节点A调整其节能开关参数为该第一网络配置指令所携带的节能开关参数；又例如，该第一网络配置指令为调整关断时段和关断门限，则目标网络节点集合中的网络节点A按照该第一网络配置指令所要求的关断时段调整其自身的关断时段，以及按照该第一网络配置指令所要求的关断门限调整其自身的关断门限。目标网络节点集合中的网络节点A执行该第一网络配置指令，可以使得目标网络节点集合整体的网络节能效果与网络性能损失可以满足第一网络节能模式，从而可以在实现网络节能的同时协调网络节能效果与网络性能损失之间的关系。
S258、第二网络管理单元获取目标网络节点集合中的网络节点A的第二业务场景信息。
在执行节能操作过程中，目标网络节点集合中的网络节点A的网络业务数据可能发生变化，目标网络节点集合中的网络节点A的网络业务数据的变化可能会影响目标网络节点集合的网络节能效果与网络性能损失，使得目标网络节点集合的网络节能效果与网络性能损失不能满足第一网络节能模式。因此，目标网络节点集合中的网络节点A可以定时或不定时地向第二网络管理单元或其管理单元发送第二网络业务数据；或者目标网络节点集合中的网络节点A在检测到自身的网络业务数据发生变化时，向第二网络管理单元或其管理单元发送第二网络业务数据。该第二网络业务数据可以与第一网络业务数据相同或不同。
第二网络管理单元根据第二网络业务数据，获取目标网络节点集合中网络节点A的第二业务场景信息。
该步骤的具体实现可参考本实施例的步骤S255。该第二业务场景信息可以与第一业务场景信息相同或不同。
基于获取的第二业务场景信息，第二网络管理单元可能确定不向网络节点A发送进一步的网络配置指令。例如，根据第二业务场景信息，第二网络管理单元确定网络节点的话务量变化较小，可以维持以此前网络配置指令中下发的网络配置参数运行而仍可满足第一网络节能模式，因此确定不再发送新的网络配置指令，则不执行S259及之后的步骤。以下假设第二网络管理单元确定向网络节点A发送进一步的网络配置指令。
S259、第二网络管理单元基于第一网络节能模式和第二业务场景信息确定第二网络配置参数，第二网络配置参数用于使网络节点A以节约能量的工作状态运行。
该步骤的具体实现可以参考本实施例的步骤S256。该第二网络配置参数可以与第一网络配置参数相同或不同。
S260、第二网络管理单元向网络节点A或网络节点A的管理单元发送第二网络配置指令， 该第二网络配置指令包括第二网络配置参数。相应地，该网络节点或该网络节点的管理单元接收该第二网络配置指令。
该步骤的具体实现可参考本实施例的步骤S257。
S261、网络节点A执行第二网络配置指令。
该步骤的具体实现可参考本实施例的步骤S268。
S262、网络节点A向第二网络管理单元或网络节点A的管理单元发送网络节点A的能耗数据和/或网络性能数据。
具体地，第二网络管理单元在下发上述第一网络配置指令/第二网络配置指令之后，可以从网络节点A采集数据，获得网络节点A执行第一网络配置指令和/或第二网络配置指令之后目标网络节点集合中的网络节点A的能耗和/或网络性能。具体地，在一个实现中，第二网络管理单元可以向目标网络节点集合中的网络节点A发送获取请求，以请求获取该网络节点A执行第一网络配置指令和/或第二网络配置指令之后网络节点A的能耗和/或网络性能；该网络节点A向第二网络管理单元发送其执行第一网络配置指令和/或第二网络配置指令之后的能耗和/或网络性能。在另一个实现中，也可以是该网络节点A在执行完第一网络配置指令/第二网络配置指令之后，向第二网络管理单元发送网络节点的能耗和/或网络性能。
可以理解的是，可以在第二网络管理单元在下发上述第一网络配置指令和第二网络配置指令之后，且目标网络节点集合中的网络节点A执行第一网络配置指令和第二网络配置指令之后，目标网络节点集合中的网络节点A发送其能耗和/或网络性能。也可以是第二网络管理单元在每次下发新的网络配置指令(即行第一网络配置指令或第二网络配置指令)之后，且目标网络节点集合中的网络节点A执行该网络配置指令之后，目标网络节点集合中的网络节点A发送其能耗和/或网络性能。
类似地，第二网络管理单元还获取目标网络节点集合中除了网络节点A之外的网络节点的能耗数据和/或网络性能数据。
S263、第二网络管理单元根据目标网络节点集合中的所有网络节点的能耗数据和/或网络性能数据，生成节能控制结果。
第二网络管理单元在接收到目标网络节点集合中的所有网络节点发送的网络节点的能耗数据和/或网络性能数据之后，根据上述能耗数据和/或网络性能数据，生成节能控制结果。该节能控制结果为对目标网络节点集合进行节能控制的结果。
具体地，第二网络管理单元根据接收到的目标网络节点集合中的所有网络节点的能耗数据与没有进行节能控制时记录的目标网络节点集合中的所有网络节点的历史能耗数据，计算目标网络节点集合的网络节能效果；并根据接收到的目标网络节点集合中的所有网络节点的网络性能数据与没有进行节能控制时记录的目标网络节点集合中的所有网络节点的历史网络性能数据，计算目标网络节点集合的网络性能损失；然后，第二网络管理单元解析第一网络节能模式，根据计算出的目标网络节点集合的网络性能损失和网络节能效果，然后将得到的目标网络节点集合的网络性能损失和网络节能效果与第一网络节能模式进行比较，得到节能控制结果。
其中，在计算目标网络节点集合的网络节能效果时，可以是将目标网络节点集合中的所有网络节点的能耗数据相加(或者加权相加)，并将没有进行节能控制时记录的目标网络节点集合中的所有网络节点的历史能耗数据相加(或者加权相加)，然后根据两个相加的结果计算目标网络节点集合的网络节能效果。
其中，在计算目标网络节点集合的网络性能损失时，可以是将目标网络节点集合中的所有网络节点的网络性能数据取平均值，并将没有进行节能控制时记录的目标网络节点集合中的所有网络节点的历史网络性能数据取平均值，然后根据两个平均值计算目标网络节点集合的网络性能损失。
具体地，该节能控制结果包含：表示目标网络节点集合的网络节能效果和网络性能损失是否满足第一网络节能模式的信息，或者表示目标网络节点集合的网络节能效果和网络性能损失与第一网络节能模式之间的差距。
其中，目标网络节点集合的网络节能效果和网络性能损失是否满足第一网络节能模式包括两种情况：第一种情况是，网络节能效果和网络性能损失满足第一网络节能模式(或者称达成预期)；第二种情况是，网络节能效果和网络性能损失不满足第一网络节能模式(或者称未达成预期)。从而，目标网络节点集合的网络节能效果和网络性能损失是否满足第一网络节能模式的信息可以为1个比特，当该比特值为“1”时，表示上述第一种情况；当该比特值为“0”时，表示上述第二种情况。反之亦可。例如，假设第一网络节能模式包括网络性能损失与相应网络节能效果之间的比值的范围(如上限)，第二网络管理单元根据接收到的目标网络节点集合的能耗和/或网络性能，分别计算网络性能损失和网络节能效果，然后再计算网络性能损失与网络节能效果之间的比值，然后判断计算出的比值是否在第一网络节能模式所包括的比值的范围内，若是，则可以确定网络节能效果和网络性能损失满足第一网络节能模式。
其中，目标网络节点集合的网络节能效果和网络性能损失与第一网络节能模式之间的差距也可以包括两种情况，第一种情况是目标网络节点集合的网络节能效果和网络性能损失与第一网络节能模式之间的差距大于或等于预设阈值；第二种情况是目标网络节点集合的网络节能效果和网络性能损失与第一网络节能模式之间的差距小于预设阈值。该差距可以采用1比特表示，该比特的值为“1”时，表示上述第一种情况；该比特的值为“0”时，表示上述第二种情况。反之亦可。该预设阈值可以根据经验或历史数据进行设置。假设第一网络节能模式包括网络性能损失与相应网络节能效果之间的比值的范围(如上限)，第二网络管理单元根据接收到的目标网络节点集合的能耗和/或网络性能，分别计算网络性能损失和网络节能效果，然后再计算网络性能损失与网络节能效果之间的比值，然后计算该比值与第一网络节能模式所包括的上限之间的差距，然后比较该差距是否大于或等于预设阈值。
S264、第二网络管理单元向第一网络管理单元发送节能控制结果。相应地，第一网络管理单元接收该节能控制结果。
第二网络管理单元向第一网络管理单元发送节能控制结果。在一个实现方式中，第二网络管理单元可以向第一网络管理单元发送节能反馈消息。该节能反馈消息包括上述节能控制结果。相应地，第一网络管理单元接收该节能反馈消息。
进一步地，第二网络管理单元还可以根据节能控制结果，更新上述场景化的网络节能模式与网络配置参数的关联关系模型。
S265、第一网络管理单元根据节能控制结果向第二网络管理单元发送第二节能控制消息，该第二节能控制消息包括第二网络节能模式，第二网络节能模式用于表示对目标网络节点集合的网络节能效果与网络性能损失的第二要求。
具体地，第一网络管理单元在接收到第二网络管理单元发送的网络节能模式执行结果后，若网络节能模式执行结果为网络节能效果和网络性能损失未满足第一网络节能模式，或者网络节能效果和网络性能损失之间的关系与第一网络节能模式之间的差距大于或等于预设阈 值，则第一网络管理单元根据上述节能控制结果得到第二网络节能模式，所述第二网络节能模式用于表示对所述目标网络节点集合的网络节能效果与网络性能损失的第二要求。
例如，假设第一网络节能模式为性能微损模式，其具体要求包括网络性能损失与相应网络节能效果之间的比值的范围(如上限10％)，如果目标网络节点执行第一网络配置指令后，其节能控制结果为目标网络节点集合的网络节能效果和网络性能损失不满足第一网络节能模式，则需调整为第二网络节能模式，例如，性能无损网络节能模式。
然后，第一网络管理单元向第二网络管理单元发送第二节能控制消息，该第二节能控制消息包括上述第二网络节能模式。相应地，第二网络管理单元接收该第二节能控制消息。
该步骤的具体实现可参考图4所示实施例的步骤S142或本实施例的步骤S253，所不同的是，下发第二节能控制消息时，网络节能范围信息可以与第一节能控制消息中的网络节能范围信息相同，也可以不同。若第二节能控制消息中的网络节能范围信息与第一节能控制消息中的网络节能范围信息不同，则该第二节能控制消息还可以包括更新的网络节能范围信息。
例如，假设第一节能控制消息中，网络节能范围信息包含的将进行节能操作的网络节点的地理位置为“海淀区”，则将海淀区范围内的网络节点作为目标网络节点集合。然而，第二网络管理单元反馈的节能控制结果为目标网络节点集合的网络节能效果与网络性能损失未满足第一网络节能模式，则第一网络管理单元可以重新确定网络节能范围信息，例如确定的网络节能范围信息包含的将进行节能操作的网络节点的地理位置为“海淀区某工业园区”，即缩小了网络节能范围(假设缩小网络节能范围可以提高网络节能效果)，则将海淀区某工业园区范围内的网络节点作为目标网络节点集合。第二节能控制消息中包含该重新确定的网络节能范围信息。
S266、第二网络管理单元根据第二节能控制消息触发目标网络节点集合进行节能操作，以使目标网络节点集合的节能效果与网络性能损失之间的关系满足第二网络节能模式。
该步骤的具体实现可参考上述步骤S254～S265。实施步骤S264～S266，第一网络管理单元还可以根据第二网络管理单元反馈的节能控制结果，调整下发给第二网络管理单元的网络节能模式，使得目标网络节点集合的网络节能效果与网络性能损失尽可能满足下发的网络节能模式。
