Description
重叠覆盖网络的能效参数获取方法、 装置和网络管理系统 技术领域 本发明涉及通信技术，尤其涉及一种重叠覆盖网络的能效参数获取方法、 装置和网络管理系统。 背景技术 在通信网络中， 网络能效是衡量网络单位能耗的有益产出的关键性能指 标（ Key Performance Indicator, 以下筒称 KPI )。 目前对于网络能效的测量方 法和评估方式, H欠洲电信标准 4匕十办会 ( European Telecommunications Standards Institute, 以下筒称 ETSI ) 的能耗效率 (Energy Efficiency, 以下筒称 EE)项目 对无线接入网（ Radio Access Network, 以下筒称 RAN )中的基站设备进行了 建模分析， 提出了针对网络设备级与站点级的能耗测量方法以及针对网络级 的能效评估方式。 ETSI同时也定义了网络能效就是能耗与能耗的有益产出之 间的关系。 伴随着用户数量的增长和数据业务的快速增长， 运营商也越来越 重视网络能效的状况。
在 3GPP提出了小区重叠覆盖和容量受限的网络两类小区级节能用例（统 称为重叠覆盖网络）， 现有技术没有给出评估该类小区级节能用例能效 KPI 的具体方法， 从而运营商也无法了解通过小区节能带来的能效实际增益。 发明内容 本发明实施例提供一种重叠覆盖网络的能效参数获取方法、 装置和网络 管理系统， 以及无线接入网设备和通信系统。

本发明实施例， 主要是基于第三代伙伴计划 （3rf Generation Partnership Project, 以下筒称 3GPP )提出的两个小区级节能开关用例来进行能效参数的 获取。 这两个节能开关用例分别针对小区重叠覆盖（ Cell Overlaid )和容量受 限的网络（Capacity Limited Network ) , 统称为重叠覆盖网络。 这两种节能
开关用例有一个共同的特点， 当小区进入节能状态时， 都需要在周围有为它 提供覆盖支撑的小区。 也就是， 由提供覆盖支撑的小区来为进入节能状态的 小区内的原用户继续提供服务。 对于小区重叠覆盖的节能开关用例， 提供覆 盖支撑的小区和节能小区是在网络规划及部署阶段就预先生成的静态小区关 系， 而容量受限的网络节能开关用例中， 提供覆盖支撑的小区和节能小区则 是在节能过程中通过节能补偿操作生成的动态小区关系。

所述的性能测量参数中， 所述能效测量区域内目标小区的业务流服务质 量参数包括如下任一参数或其组合：
用户吞吐量、 时延、 丢包率或活动用户数。 其中， 所述用户吞吐量可以 包括最差 5 %的用户吞吐量（ 5th percentile user throughput， 反映 、区边缘的用 户吞吐量）、最好 5%的用户吞吐量 (95th percentile user throughput,反映小区中 心的用户吞吐量)或者平均用户吞吐量 (50th percentile user throughput)任一参 数或其组合。
图 3为本发明实施例提供的在重叠覆盖网络中从无线接入网设备侧获取 能效参数的方法流程图， 其步骤如下：
S300, 无线接入网设备接收网络管理系统发送测量指示， 所述测量指示 用于指示所述无线接入网设备在能效测量周期内测量所述能效测量区域内目 标小区的性能测量参数， 以及所述无线接入网设备在所述能效测量周期内的 能耗值；
S302, 无线接入网设备获取能效测量区域内目标小区在能效测量周期内 的性能测量参数， 以及所述无线接入网设备在能效测量周期内的能耗值并向
所述网络管理系统上报。
具体的， 所述无线接入网设备的能耗值的获取方法， 可以采用无线接入 网设备内部的能耗监控模块， 在能效测量周期内将无线接入网设备各组成模 块或器件的能耗值进行采集求和， 获得无线接入网设备整机能耗的一个组合 测量结果； 或者可以采用外挂功率 /能耗测试仪表的方法， 通过仪表直接测量 采集在能效测量周期内无线接入网设备的能耗值。
本发明实施例提供一种针对小区节能开关用例能效参数的有效获取方 法， 无线接入网络接收到网络管理系统发送的性能测量指示后开始获取能效 测量区域中的能效参数， 从而帮助运营商了解小区节能开关用例带来的实际 增益。
对于本发明实施例提供的重叠覆盖网络的能效参数获取方法， 其中所述 测量指示包括所述能效测量周期、 能效测量区域信息、 性能测量参数信息和 能效测量启动指示； 或者在所述无线接入网设备中预先配置所述能效测量周 期、 能效测量区域信息和性能测量参数信息。 其中所述性能测量参数信息包 括需要测量的如下参数的任一或其组合：
所述能效测量区域内目标小区的负载参数、 所述能效测量区域内目标小 区间的干扰参数或所述能效测量区域内目标小区的业务流服务质量参数。
具体的， 当小区节能开关用例需要进行能效参数的测量时， 无线接入网 设备接收来自网络管理系统发送的测量指示， 测量指示包括所述能效测量周 期、 能效测量区域信息、 性能测量参数信息和能效测量启动指示， 无线接入 网设备根据所述能效测量启动指示开始进行能效测量操作， 所述能效测量操 作根据所提供的能效测量周期， 在所规定的能效测量区域内对性能测量参数 信息指定的参数进行能效测量。
也可以在无线接入网设备中预先将所述能效测量周期、 所述能效测量区 域信息和所述性能测量参数信息设置好， 当无线接入网设备接收到网络管理 系统发送的测量指示时， 无线接入网设备根据接收到的所述能效测量启动指 示启动测量操作， 根据已经预设的能效测量周期在规定的能效测量区域内对 通过性能测量参数信息预设好的任一或其组合的性能测量参数进行能效测 量。
这里对所述性能测量参数信息包括需要测量的参数的任一或其组合做进
一步说明：
本发明实施例需要测量的性能测量参数可以是所述能效测量区域内目标 小区的负载参数、 所述能效测量区域内目标小区间的干扰参数或所述能效测 量区域内目标小区的业务流服务质量参数这三者中的任意一个， 也可以是它 们中两两的任一组合， 或者是包括全部该三种参数。
例如当网络管理系统只需要基于所述能效测量区域内目标小区间的干扰 参数下的能耗值时， 网络管理系统可以将需要测量的性能测量参数设置为仅 包括能效测量区域内目标小区间的干扰参数；
当网络管理系统需要基于所述能效测量区域内目标小区间的干扰参数和 所述能效测量区域内目标小区间的干扰参数下的能耗值时， 网络管理系统可 以将需要测量的性能测量参数设置为包括所述能效测量区域内目标小区间的 干扰参数和所述能效测量区域内目标小区的业务流服务质量参数；
当网络管理系统需要基于所述能效测量区域内目标小区的负载参数、 所 述能效测量区域内目标小区间的干扰参数或所述能效测量区域内目标小区的 业务流服务质量参数下的能耗值时， 网络管理系统可以将需要测量的性能测 量参数设置为包括全部该三种参数， 即所述能效测量区域内目标小区的负载 参数、 所述能效测量区域内目标小区间的干扰参数或所述能效测量区域内目 标小区的业务流服务质量参数。
也就是说， 在性能测量参数通过所述测量指示发送给无线接入网设备的 情况下，所述性能测量参数的任一或组合可以由所述网络管理系统自行选择； 在所述接入网设备中预先设置所述性能测量参数的情况下， 所述性能测 量参数的任一或组合由具体的网络类型来决定， 例如， 当节能小区和提供覆 盖支撑的小区同属于一个无线接入技术（ Radio Access Technology )时， 两个 小区提供业务的能力或服务质量相同， 因此在这种情况下， 可以不考虑业务 流服务质量参数。此时无线接入网设备可以不设置测量业务流服务质量参数， 即在无线接入网设备中只预先设置测量所述能效测量区域内目标小区的负载 参数和所述能效测量区域内目标小区间的干扰参数两个参数。

本发明实施例提供一种通信系统， 其中包括， 所述的网络管理系统和所 述无线接入网设备。
其中所述的网络管理系统和无线接入网设备上文已进行了详细介绍， 此 处不再赘述。
本发明实施例提供的通信系统， 通过所述网络管理系统向所述无线接入 网设备发送测量指示， 所述无线接入网设备接收所述网络管理系统发送的测
量指示， 在能效测量区域内进行相应的性能测量参数和能耗值的测量， 然后 将测量的到的性能测量参数和相应的能耗值发送给所述网络管理系统， 所述 网络管理系统接收性能测量参数和相应的能耗值，计算得到相应的能效参数， 从而帮助运营商准确地了解小区节能开关用例带来的实际增益。
下面结合图 4、 图 5和图 6对本发明实施例提供的通信系统进行具体的 说明。
小区节能开关用例开启后， 运营商可以对能效测量区域内目标小区的能 效参数进行测量， 首先由网络管理系统向无线接入网设备发送测量指示。
具体的， 所述测量指示是通过所述网络管理系统中所述第一获取单元的 所述第一发送子单元发送。
其中所述测量指示可以包括。 所述能效测量周期、 所述能效测量区域信 息、 所述性能测量参数信息和所述能效测量启动指示； 也可以在所述无线接 入网设备中预先配置所述能效测量周期和能效测量区域信息和性能测量参数 信息。
所述无线接入网设备通过所述第一接收单元接收测量指示， 根据测量指 示进行相应的测量， 将所测得的性能测量参数和相应的能耗值通过所述第一 发送单元发送给所述网络管理系统， 所述网络管理系统通过第一接收子单元 接收所测得的性能测量参数和相应的能耗值， 根据所述性能测量参数和所述 相应的能耗值通过所述第二获取单元进行计算， 从而得到该小区节能用例的 能效参数， 帮助运营商准确地了解小区节能开关用例带来的实际增益。
对于本发明实施例提供的重叠覆盖网络的能效参数获取方法， 是基于两 个具体的小区节能开关用例来实现的， 对于这两个小区节能开关用例它们的 能效测量范围是不同的。
图 7为针对小区重叠覆盖的节能开关用例的能效测量区域范围， 其能效 测量范围包括进行节能的小区 A, 以及为该节能小区提供覆盖支撑的一个或 者多个小区 B。 图 8为针对容量受限的网络的节能开关用例的能效测量区域 范围， 其能效测量范围包括图 8中的全部区域， 其中小区 C执行节能补偿操 作， 小区 D、 小区 E、 小区 F和小区 G则执行节能激活或去激活操作。
重叠覆盖网络的能效参数测量是在能效测量区域范围中进行的。 例如， 在小区重叠覆盖的场景中， 需要测量进行节能的小区和进行覆盖支撑的小区
的整体能耗情况， 同时测量该测量区域内目标小区的性能测量参数， 例如进 行节能的小区和进行覆盖支撑的小区的负载参数。
本发明实施例提供的重叠覆盖网络的能效参数获取方法， 对于所述性能 测量参数中的目标小区的负载参数， 在评估重叠覆盖网络的能效时， 需要将 该目标小区的负载情况考虑进来， 也就是说， 目标小区在不同负载情况下的 能耗是多少。 3GPP规范将小区的负载状态分为： 低负载（Low Load ) , 中 等负载（ Medium Load )和高负载 ( High Load ) 。 判断一个小区处于不同的 负载状态， 可以采用将小区实际测量的负载值和一个预先设置的负载门限进 行比较。 例如： 当小区实际测量的负载值低于某一负载门限 1时， 判断该小 区处于低负载状态； 当小区实际测量的负载值高于或等于门限 1并且低于另 一个负载门限 2时， 判断该小区处于中等负载状态； 当小区实际测量的负载 值高于或等于负载门限 2时， 判断该小区处于高负载状态。
本发明实施例提供的重叠覆盖网络的能效参数获取方法， 对于所述能效 测量区域内目标小区的业务流服务质量参数， 在小区节能开关用例中， 在进 行小区节能之前将需要进行节能的小区中剩余的少量活动用户迁移到提供节 能覆盖支撑的小区， 对这一迁移过程的基本要求是保证迁移的用户或者业务 流的服务质量不因为小区节能而产生显著的负面影响。 一般的， 当节能小区 和提供覆盖支撑的小区同属于一个无线接入技术时， 两个小区提供业务的能 力或服务质量相同， 因此在这种情况下， 可以不考虑业务流服务质量参数。 如果节能小区和提供覆盖支撑的小区属于不同的无线接入技术， 那么业务流 服务质量参数是一个必要获取的能效参数。
对于 LTE (Long Term Evolution)业务流，可以分为连续业务流（ Continuous Traffic )和突发业务流（ Bursty Traffic ) , 不同的业务流类型具有不同的业务 流服务质量参数。 对于连续业务流， 该类业务对吞吐量、 带宽的要求较高， 其业务流服务质量参数包括： 用户吞吐量和 /或时延； 对于突发业务流， 该类 业务对吞吐量的要求不高， 但是对传输的丢包率要求较高， 其业务流服务质 量参数主要包括： 丢包率（ Packet Loss Rate ) 。 此外， 对于不同的连续业务 流或突发业务流， 活动用户数 ( Active UE Number )可以作为一个与业务类 型无关的通用的业务流服务质量参数。
针对本发明实施例定义的三类能效参数： 能效测量区域内目标小区的负
载参数、 能效测量区域内目标小区的干扰参数、 能效测量区域内目标小区的 业务服务流服务质量参数， 本发明实施例提出了测量能效参数的相应过程。
本发明上述实施例中， 其中的网络管理系统在对某一能效测量区域内目 标小区的能效参数进行测量时， 可以是创建一个性能测量任务， 然后根据该 性能测量任务， 向无线接入网设备发送测量指示， 来获取能效测量区域内目 标小区的性能测量参数。 同时网络管理系统还获取相同能效测量周期内在相 同的能效测量区域内目标小区所属的无线接入网设备的能耗值。 并最终根据 上述的目标小区性能测量参数和目标小区所属无线接入设备的能耗值的测量 结果， 计算重叠覆盖网络能效测量区域的能效 KPI, 具体的， 能效 KPI可以 表示为一类性能测量参数下的能耗值， 有如下几种形式：
一是能效测量区域内的能效 KPI 可以是该区域相应负载水平下的能耗 值， 具体地说， 就是该能效测量区域内无线接入设备的总体能耗值与该能效 测量区域内小区负载的求和效果的比值；
二是能效测量区域内的能效 KPI可以是该区域相应的小区间干扰参数下 的能耗值， 具体地说， 就是该能效测量区域内无线接入设备的总体能耗值与 该能效测量区域内小区间干扰参数的测量结果的比值；
三是对于能效测量区域内的能效 KPI可以是该区域相应的业务流服务质 量参数下的能耗值， 具体地说， 就是该能效测量区域内无线接入设备的总体 能耗值与该能效测量区域内业务流服务质量（用户吞吐量、 时延、 丢包率或 活动用户数） 的测量结果的比值。
或者， 能效 KPI还可以表示为单位能耗输出的相应性能测量参数结果， 有如下几种形式：
一是单位能耗所支撑的小区负载情况。 具体地说， 就是该能效测量区域 内的小区负载测量的求和效果和该测量区域内无线接入网设备产生能耗的比 值。
二是该能效测量区域内单位能耗下的小区间干扰参数下的测量值； 具体 地说， 就是该能效测量区域内的小区间干扰的测量结果和该测量区域内无线 接入网设备产生能耗的比值。
三是该能效测量区域内单位能耗下的小区业务流服务质量的测量值； 具 体地说， 就是该能效测量区域内的业务流服务质量的测量结果和该测量区域
内无线接入网设备产生能耗的比值。
最后应说明的是： 以上实施例仅用以说明本发明的技术方案， 而非对其 限制； 尽管参照前述实施例对本发明进行了详细的说明， 本领域的普通技术 人员应当理解： 其依然可以对前述实施例所记载的技术方案进行修改， 或者 对其中部分技术特征进行等同替换； 而这些修改或者替换， 并不使相应技术 方案的本质脱离本发明实施例技术方案的精神和范围。
