具体实施方式
下文中将结合附图对本申请的实施例进行详细说明。
随着全球能源和环境问题的日益突出，全球标准组织、运营商、设备商都已经投入到节能减排的活动中来。在一些无线通信网络中，电能的消耗主体是无线基站，因此，基站成为节能减排的重点对象，大量的节能减排技术被应用到基站中。
目前，随着通信系统对流量需求的不断增长，从第二代移动通信技术(2nd-Generation，2G)逐渐发展到第五代移动通信技术(5th-Generation，5G)，基站带宽已经从千赫兹(K)级别增长到100兆赫兹(MHz)级别以上。为了保证基站的稳定覆盖，基站的输出功率也随之增大(基站的功耗也越来越大)，对于5G基站来说甚至已经达到了1500瓦(W)级别，如果按照传统的每个基站都按照最大功率配电，并且考虑高温导致基站功耗上升等因素，为基站保留一定的余量，那么对供电设备的要求很高，容易造成资源的浪费。
基站能耗的主要器件是功率放大器(Power Amplier，PA)，其实际功耗与输出功率强相关，输出功率又与业务负荷有关。由于业务负荷是波动的，很难在较长时间内持续保持峰值 (会在某一个瞬间达到最大值)，尤其是多个基站同时出现峰值的概率比较低，绝大部分时间段基站的平均输出功率都在30％以下。因此，可以通过控制基站的业务负荷调整基站的输出功率，进而控制基站的能耗。
本申请实施例提供了一种移动通信网络(包括但不限于第五代移动通信网络(5th-Generation，5G))，该网络的网络架构可以包括网络侧设备(例如一种或多种类型的基站，传输节点，接入节点(Access Point，AP)，中继，节点B(Node B，NB)，陆地无线电接入(Universal Terrestrial Radio Access，UTRA)，演进型陆地无线电接入(Evolved Universal Terrestrial Radio Access，EUTRA)等)和终端设备(用户设备(User Equipment，UE)，用户设备数据卡，中继(relay)，移动设备等)。
图1为本申请实施例提供的一种移动通信网络的架构图，如图1所示，移动通信网络包括M个基站(M≥2)(图1中以基站1、基站2、…基站M分别标示)，M个基站属于一个节能簇，节能簇对应一个供电设备(即一个供电设备同时为M个基站供电)，每个基站包括若干个小区，UE可以通过接入某个小区达到接入某个基站的目的。在本申请实施例中，提供一种可运行于上述网络架构的节能方法、装置，通信节点及计算机可读存储介质，能够动态调节通信节点的功率输出，大大降低对供电设备的需求，实现节能减排。本申请实施例中提供的上述节能方法的运行环境并不限于上述网络架构。
本申请中术语“系统”和“网络”在本申请中常被可互换使用。本申请的说明书和权利要求书及附图中的术语“第一”、“第二”、“第三”等是用于区别不同对象，而不是用于限定特定顺序。本申请下述各个实施例可以单独执行，各个实施例之间也可以相互结合执行，本申请实施例对此不作具体限制。
下面，对节能方法、装置及其技术效果进行描述。
图2为本申请实施例提供的一种节能方法的流程示意图，如图2所示，本实施例提供的方法适用于第一通信节点(如上述图1所示的移动通信网络中的任一基站，以基站1为例，本申请中提到的第二通信节点除了基站1以外的其他基站)，该方法包括如下步骤。
S110、第一通信节点获取第二通信节点的供电能力信息，其中，第一通信节点和第二通信节点属于一个节能簇，节能簇对应一个供电设备。
在一实施例中，供电能力信息包括功率输出档位，第一通信节点的功率输出档位与第二通信节点的功率输出档位之和小于或者等于供电设备的额定功率。
在一实施例中，第一通信节点可以依据功率输出档位映射第一通信节点小区的小区功率 因子，小区功率因子与小区的业务负荷能力相关。
S120、第一通信节点根据自身的供电能力信息、第二通信节点的供电能力信息以及供电设备的额定功率，控制第一通信节点的功率输出。
在一实施例中，第一通信节点可以根据小区的业务负荷能力控制业务接入，进而实现控制第一通信节点的功率输出(即小区负荷控制)。可选的，第一通信节点可以控制上下行无线资源负荷、用户数、上下行吞吐量等(例如：负荷均衡策略，负荷控制，拥塞策略等)控制第一通信节点的功率输出。
在一实施例中，第一通信节点可以周期性地比较当前时刻的实际输出功率(即当前时刻第一通信节点的功率负荷需求)与第一通信节点的功率输出档位之间的关系，并通过小区负荷控制方法和功率输出档位调节策略中的至少一项来控制第一通信节点的功率输出。
下面，分别对小区负荷控制方法和功率输出档位调节策略进行介绍，可以理解的是，第一通信节点可以单独采用小区负荷控制方法控制自身的功率输出，也可以单独采用功率输出档位调节策略控制自身的功率输出，还可以同时采用小区负荷控制方法和功率输出档位调节策略控制自身的功率输出。
第一通信节点通过功率输出档位调节策略控制自身的功率输出的方法可以包括：若第一通信节点的功率输出档位高于当前时刻第一通信节点的功率负荷需求，表示当前时刻第一通信节点处于空闲态，第一通信节点可以自行或者在其他通信节点(如第二通信节点)的请求下，降低第一通信节点的功率输出档位；或者，若第一通信节点的功率输出档位低于当前时刻第一通信节点的功率负荷需求，表示当前时刻第一通信节点处于忙碌态，第一通信节点可以自行或者在与其他通信节点(如第二通信节点)协商后，提高第一通信节点的功率输出档位。
当然，调整后的第一通信节点的功率输出档位与第二通信节点的功率输出档位之和仍旧需要小于或者等于供电设备的额定功率。
供电能力信息还包括优先级；第一通信节点通过小区负荷控制来控制自身的功率输出的方法可以包括：若第一通信节点的功率输出档位高于当前时刻第一通信节点的功率负荷需求，且第一通信节点的优先级高于第二通信节点的优先级(即第三通信节点(如UE)优先接入第一通信节点)，由于当前时刻第一通信节点处于空闲态，因此，第一通信节点允许第三通信节点优先接入，以提高当前时刻第一通信节点的功率负荷需求；或者，若第一通信节点的功率输出档位低于当前时刻第一通信节点的功率负荷需求，且第一通信节点的优先级高 于第二通信节点的优先级(即第三通信节点(如UE)优先接入第一通信节点)，由于当前时刻第一通信节点处于忙碌态，因此，第一通信节点调节第一通信节点的优先级低于第二通信节点的优先级，使得第三通信节点优先接入第二通信节点，降低当前时刻第一通信节点的功率负荷需求，提升当前时刻第二通信节点的功率负荷需求，保证了节能簇中各通信节点功耗均衡；或者，若第一通信节点的功率输出档位高于当前时刻第一通信节点的功率负荷需求，第二通信节点的功率输出档位低于当前时刻第二通信节点的功率负荷需求，且第一通信节点的优先级低于第二通信节点的优先级(即第四通信节点(如UE)优先接入第二通信节点)，由于当前时刻第一通信节点处于空闲态，第二通信节点处于忙碌态，因此，第一通信节点调节第一通信节点的优先级高于第二通信节点的优先级，以允许第四通信节点优先接入，提升当前时刻第一通信节点的功率负荷需求，降低当前时刻第二通信节点的功率负荷需求，保证了节能簇中各通信节点功耗均衡。
在一实施例中，通信节点的功率输出档位与通信节点的小区的小区功率因子关联，小区功率因子用于指示业务负荷能力。以第一通信节点和第二通信节点为例，第一通信节点的功率输出档位与第一通信节点的小区(以下简称小区A)的小区功率因子关联，第二通信节点的功率输出档位与第二通信节点的小区(以下简称小区B)的小区功率因子关联，假设供电设备的额定功率为1000W，表1示出了一种第一通信节点和第二通信节点的功率输出档位与其对应的小区功率因子的关联表。
表1
Figure PCTCN2020130573-appb-000001
从表1可以看出，在第一组中，第一通信节点的功率输出档位为300W，第二通信节点的功率输出档位为650W，第一通信节点的功率输出档位与第二通信节点的功率输出档位之和小于供电设备的额定功率为1000W，并且第一通信节点的小区A的小区功率因子为30％，即小区A的业务负荷门限(也称为业务信道负荷利用率门限)为30％。当小区A的业务负荷达到30％时，表示第一通信节点当前时刻的功率负荷需求近似等于功率输出档位的300W。 同理，第二通信节点的小区B的小区功率因子为60％，即小区B的业务负荷门限为60％。当小区B的业务负荷达到60％时，表示第二通信节点当前时刻的功率负荷需求近似等于功率输出档位的650W。
在第二组中，第一通信节点的功率输出档位为500W，第二通信节点的功率输出档位为500W，第一通信节点的功率输出档位与第二通信节点的功率输出档位之和等于供电设备的额定功率为1000W，并且第一通信节点的小区A的小区功率因子为50％，当小区A的业务负荷达到50％时，表示第一通信节点当前时刻的功率负荷需求近似等于功率输出档位的500W。同理，第二通信节点的小区B的小区功率因子为50％，当小区B的业务负荷达到50％时，表示第二通信节点当前时刻的功率负荷需求近似等于功率输出档位的500W。
在上述实施例的基础上，图3为本申请实施例提供的另一种节能方法的流程示意图，如图3所示，该方法还包括如下步骤。
S130、第一通信节点广播自身的供电能力信息。
需要说明的是，第一通信节点可以周期性地广播自身的供电能力信息，或者当自身的供电能力信息包括的功率输出档位和优先级中的至少一项发生变化时，第一通信节点广播自身的供电能力信息。
本申请实施例提供一种节能方法，包括第一通信节点获取第二通信节点的供电能力信息，其中，第一通信节点和第二通信节点属于一个节能簇，节能簇对应一个供电设备；第一通信节点根据自身的供电能力信息、第二通信节点的供电能力信息以及供电设备的额定功率，控制第一通信节点的功率输出。本申请能够动态调节通信节点的功率输出，大大降低对供电设备的需求，实现节能减排。
下面罗列一些示例性实施方式，用于说明本申请实施例提供的节能方法。在下述示例性实施方式可以单独执行，也可以相互结合执行，本申请实施例对此不作具体限制。示例性的，下述实施例中分别是以第一通信节点和第二通信节点为一个节能簇下的不同基站，第三通信节点和第四通信节点为可接入基站的UE为例进行说明的。
在一个示例性的实施例中，假设一个节能簇中包括基站X和基站Y，基站X和基站Y共享配电能力，基站X和基站Y之间交互供电能力信息。基站X和基站Y可以根据供电设备的额定功率，通过小区负荷控制或功率输出档位调节策略来控制自身的功率输出。
以基站X为例，基站X通过小区负荷控制和功率输出档位调节策略来控制自身的功率输出的说明如下。
首先，基站X在第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)技术规范(Technical Specification，TS)38.331的广播消息SystemInformationBlockType4中增加EnergySavingCellInfo指示优先级，即UE优先选择优先级较高的小区接入。
