下面将结合本发明实施例中的附图, 对本发明实施例中的技术方案进 行清楚、 完整地描述。
在进行本发明实施例的描述之前, 首先对网络管理系统, 即: OAM ( Operations, Administration and Maintenance, 运行、 维护和管理) 系统进 行说明。
OAM系统为网络提供运行、 维护和管理的功能。 参照 ITU-T电信管理 网模型, 3GPP管理过程的交互角色分为集成参考点管理者(IRPManager ) 和集成参考点代理( IRPAgent ), IRPManager的作用相当于网络管理器, 负 责整个网络的运行、 维护和管理; IRPAgent 的作用相当于网元管理器, 负 责对网络中某一类设备的运行、维护和管理。 IRPManager与 IRPAgent之间 的管理接口称为 Itf-N (即北向接口)。 在 Itf-N接口中, 定义了一些集成参 考点 (Integrated Reference Point, IRP ) 的功能逻辑实体, 如基本配置管理 集成参考点 ( Basic CM IRP )、 批量配置管理集成参考点 (Bulk CM IRP )、 通知集成参考点(Notifications IRP )等。 通过这些集成参考点提供的功能, IRP Agent向 IRP Manager提供网络管理的服务。
本发明实施例提供的基站节能管理方法, 包括集成参考点管理者 IRPManager向集成参考点代理 IRP Agent发起节能使能 /禁止过程或节能激 活 /恢复过程; 上述节能使能 /禁止过程用于允许或者禁止对基站或小区进行 节能操作; 上述节能激活过程用于使基站或小区进入节能状态, 所述节能 恢复过程用于使基站或小区退出节能状态。
具体地, IRPManager可以根据运营商的策略,向 IRP Agent发起节能使 能 /禁止过程或节能激活 /恢复过程。
以下将结合运营商基于的基站节能策略, 对基站节能管理过程进行详 细说明。
(一)节能使能 /禁止
通过 IRPManager发起的节能使能 /禁止过程,可以设置基站或小区的 节能使能 /禁止属性, 进而允许或者禁止对基站或小区进行节能操作。 IRPManager 发出 的 IRP 消 息携带节能使能 /禁止属性(例如 isEnergySavingAllowed)信息单元(IE ), 该 IE用于标识是否允许对该基站 或小区进行节能操作。 例如, IE取值可以是布尔量 True或 False, True表 示允许对该基站或小区进行节能操作, False表示不允许对该基站或小区进 行节能操作; 或者, IE取值为 1或 0, 1表示允许对该基站或小区进行节能 操作, 0表示不允许对该基站或小区进行节能操作。 利用这个 IE, 运营商 的网管维护人员可以在基站级或小区级进行节能操作使能 /禁止设置。
关于节能使能 /禁止属性的设置策略, 运营商可以依据基站或小区初期 部署阶段的网规数据、 或者投入运行一定时期后的网优数据, 确定并设置 基站或小区的节能使能 /禁止属性。 运营商在设置基站或小区的节能使能 / 禁止属性之前, 可以考虑的节能策略至少包括如下几个方面: 该基站或小 区的业务能力 (类型、 速率等)是否被其他同一区域覆盖的其他基站 /小区 所提供; 对于异系统部署环境(同一区域由不同制式的无线技术所覆盖), 是否允许在特定的时期进行业务降速(例如: 由 LTE数据速率降至 UMTS 数据速率), 等等。
按照目前 3GPP网管规范对北向接口 IRP操作的定义,可以采用以下 2 种方式发起节能使能 /禁止过程。
方式 1, IRPManager通过北向接口 Itf-N向 IRPAgent发送节能使能 / 禁止属性信息, 将节能使能 /禁止属性的设置值携带在专用的节能操作命令 中。例如, IRPManager在北向接口向 IRPAgent发送专用的节能能力设置命 令(例如 SetESCapability ), 在所述节能能力设置命令中携带节能使能 /禁止 属' ]·生 (例 isEnergySavingAllowed)的设置值 (例:^ True或 False, 1或 0 ), 所述节能能力设置命令中还包含基站标识(eNBID )或小区标识(cellID )。 IRPManager接收 IRPAgent返回的完成对所述基站或小区进行节能使能 /禁 止设置操作的通知。 IRPManager和 IRPAgent的上述交互过程如附图 1所示。
方式 2, 在北向接口对基站功能类 (例如 eNBfonction )或通用小区类
(例如 eUTRANGenericCell ) 等管理对象类增加节能使能 /禁止属性 (例如 isEnergySavingAllowed) , IRPManager通过现有的基本配置管理集成参考点 (Basic CM IRP) 或批量配置管理集成参考点 (Bulk CM IRP)操作设置该属 性。 例如: 使用管理对象属性设置 (例如 setMOAttributes )操作, 将节能 使能 /禁止属性的设置值携带在修改列表(例如 modificationList ) 消息参数 中。 例如, 该节能使能 /禁止属性的定义可参考表 1所示。
表 1 : 节能使能 /禁止属性
属性名 定义 合法值 isEnergySavingAllowed 该属性用于标识基站 设置值 {True,False}或 或小区的节能操作是 {1,0};
否允许或禁止。 True 或 1 : 允许对基站 或小区节能操作; False或 0: 禁止对基站 I I I或小区节能操作。
(二)节能生效周期
IRPManager 可以设置基站或小区的节能生效周期属性。 例如 IRPManager发出的 IRP消息携带节能生效周期信息单元( IE ), 该 IE的取 值是由起始时间和结束时间组成的时间段列表。 该 IE用于标识该基站或小 区的节能操作生效周期, 该节能操作生效周期由运营商根据一定的节能时 间策略进行设置。
例如当基站或小区的节能使能 /禁止属性被设置为使能(例如节能使能 / 禁止属性被设置为 True或 1 ), IRPManager还可以进一步向 IRP Agent发送 基站或小区的节能生效周期。 但如果基站或小区的节能使能 /禁止属性被设 置为禁止 (例如节能使能 /禁止属性被设置为 False或 0 ), 则不允许再对该 基站或小区的节能生效周期属性进行设置。
当然, 网络管理系统也可以不事先对基站或小区的节能使能 /禁止属性 进行设置, 而是由 IRPManager向 IRP Agent发送所述基站或小区的节能生 效周期; 当所述节能生效周期为有效时间值时, 表示允许对该基站或小区 进行节能操作, 当所述节能生效周期为非有效时间值时, 表示禁止对该基 站或小区进行节能操作。
在设置基站或小区的节能生效周期属性之前, 可以考虑如下两个方面 的节能策略。
策略 1: 基于 OAM系统负载统计的基站 /小区非峰值时段
按照每天 24小时(00:00:00-23:59:59)作为一个负载统计测量周期, 划 分基站 /小区的非峰值时段, 由 IRPManager根据基站 /小区的历史负载统计 数据和内部的负载阔值进行判别, 形成非峰值时段的起始 /结束时间, 时间 以 (年 -月 -日, 小时: 分种: 秒) 的形式表示, 省略 "年 -月 -日" 时默认为 每天。 例如, ( 01 :00:00, 06:00:00 )表示每天的凌晨 1点到 6点为该基站或 小区的非峰值时段。 策略 2: 热点覆盖区域基站 /小区的非忙时段
对于热点覆盖区域的基站 /小区, 例如: 体育馆、 演唱会会场、 展览馆, 在非演出 /比赛时段(即非忙时段)可以认为负载状况趋于为零。 运营商可 以获得演出 /比赛时段的时间表,通过 IRPManager将热点覆盖区域基站或小 区的非忙时段作为节能操作的生效周期设置到相应的基站或小区对象。 例 如: 将一个月内该热点覆盖区域基站 /小区的节能生效周期属性设置为 {(Ts, Tsl), (Tel, Ts2), (Te2, Ts3), ... (Te n-l, Ts n) (Te n, Te)} , 其中: Ts i和 Te i 为一个演出 /比赛时段 i的起始 /结束时间, Ts为整个统计周期的起始时间, Te为整个统计周期的结束时间, 时间的表示形式可以是: 年-月 -日, 小时: 分钟: 秒。
按照目前 3GPP网管规范对北向接口 IRP操作的定义,可以采用以下 2 种方式来完成基于上述两种策略统计出的节能生效周期属性的设置操作。
方式 1, 在北向接口 Itf-N通过专用的节能操作命令实现节能生效周期 属性设置, 节能生效周期属性的设置值携带在专用的节能操作命令。 例如: IRPManager在北向接口向 IRPAgent发送专用的节能生效周期属性设置命令 (例如 SetESPeriod ), 在所述节能生效周期属性设置命令中携带基站标识 ( eNBID )或小区标识( celllD )、以及起始时间( start time )和结束时间( end time )。 IRPManager接收 IRPAgent返回的完成对所述基站或小区进行节能 生效周期属性设置操作的通知。 IRPManager和 IRPAgent的上述交互过程如 附图 2所示。
方式 2, 在北向接口对基站功能类 (例如 eNBfonction )或通用小区类 ( 例如 eUTRANGenericCell ) 增加节 能生效周 期属性(例如 EnergySavingEffectivePeriod) , IRPManager 通过基本酉己置管理集成参考点 (Basic CM IRP) 或批量配置管理集成参考点 (Bulk CM IRP)操作设置该属 性。 例如: 使用管理对象属性设置 (例如 setMOAttributes )操作, 将节能 生效周期属性的设置值携带在修改列表(例如 modificationList ) 消息参数 中。 例如, 该节能生效周期属性的定义可参考表 2所示。
表 2: 节能生效周期属性
Figure imgf000010_0001
(三)节能激活
由 IRPManager发起的节能激活过程,用于使基站或小区进入节能状态。 节能激活的判决可以由 IRPManager根据节能操作策略直接进行,基站 执行的具体节能动作由基站自行设置, 例如: 关闭小区的载频, 关闭基站 的广播控制信道 (Broadcast Control Channel, BCCH)。 OAM系统可以无需设 置基站的具体节能动作, 但可以选择实施节能操作的控制对象(例如基站 或小区)。
按照目前 3GPP网管规范对北向接口 IRP操作的定义,可以采用以下 2 种方式来完成节能激活操作。
方式 1, IRPManager在北向接口 Itf-N向 IRPAgent发送专用的节能激 活命令 (例如 ESActivate ) , 在所述节能激活命令消息中携带基站标识 ( eNBID )或小区标识( celllD )。 IRPManager接收 IRPAgent返回的完成对 所述基站或小区节能激活操作的通知。 IRPManager和 IRPAgent的上述交互 过程如附图 3所示。
方式 2, IRPManager在北向接口对基站功能类(例如 eNBfunction )或 通用小区类 (例如 eUTRANGenericCell ) 增加节能激活属性 (例如 EnergySavingActivate ), IRPManager通过现有的基本配置管理集成参考点 (Basic CM IRP) 或批量配置集成参考点 (Bulk CM IRP)操作设置该属性。 例 如: 使用管理对象属性设置 (例如 setMOAttributes )操作, 将节能激活属 性的设置值携带在修改列表(例如 modificationList ) 消息参数中。 例如该 节能激活属性的定义可参考表 3所示。该节能激活属性由 IRPManager设置, 经由 IRPAgent透明传输给基站。 基站根据该设置的节能激活属性的取值 (True或 1)执行相应的节能激活操作。
表 3: 节能激活属性
Figure imgf000011_0001
(四)节能恢复
由 IRPManager发起的节能恢复过程,用于使基站或小区退出节能状态。 节能恢复的判决可以由 IRPManager根据节能操作策略直接进行,也可 以由处于节能状态的基站或小区相邻的非节能状态的基站或小区将同一覆 盖区域的负载变化情况通知 OAM系统, 再由 IRPManager发起节能恢复过 程。
基站或小区执行的具体节能恢复动作可由基站自行设置, 例如: 开启 小区的载频,开启基站的 BCCH信道。 OAM系统可以无需设置基站或小区 的具体节能恢复动作, 但可以选择实施节能恢复操作的控制对象(例如基 站或小区)。
按照目前 3GPP网管规范对北向接口 IRP操作的定义,可以采用以下 2 种方式来完成节能恢复操作。
方式 1, IRPManager在北向接口向 IRPAgent发送专用的节能恢复命 令(例如 ESResume ), 在所述节能恢复命令消息中携带基站标识(eNBID ) 或小区标识( celllD )。 IRPManager接收 IRPAgent返回的完成对所述基站或 小区节能恢复操作的通知。 IRPManager和 IRPAgent的上述交互过程如附图 4所示。
方式 2, IRPManager在北向接口对基站功能类(例如 eNBfunction )或 通用小区类 (例如 eUTRANGenericCell ) 增加节能恢复属性 (例如 EnergySavingResume ), IRPManager通过现有的基本配置集成参考点 (Basic CM IRP)或批量配置集成参考点 (Bulk CM IRP)操作设置该属性。 例如: 使 用管理对象属性设置 (例如 setMOAttributes )操作, 将节能恢复属性的设 置值携带在修改列表(例如 modificationList ) 消息参数中。 例如该节能恢 复属性的定义可参考表 4所示。 该节能恢复属性由 IRPManager设置, 经由 IRPAgent透明传输给基站。基站根据该设置的节能恢复属性的取值 (True或 1)执行相应的节能恢复操作。
表 4: 节能恢复属性
Figure imgf000012_0001
(五)节能状态改变通知
当基站或小区在进入节能状态或从节能状态恢复后, IRPAgent 向 IRPManager发送基站或小区节能状态改变通知。。 具体地, IRPAgent将该 基站或小区的当前节能状态通知 IRPManager, IRPAgent发出的 IRP消息携 带节能状态属性信息单元( IE )。该 IE用于标识该基站或小区当前的节能状 态。例如该属性取值可以是布尔量 True或 False, True表示该基站或小区已 经进入节能状态, False表示该基站或小区已经从节能状态中恢复; 或者该 属性取值可以是 1或 0, 1表示该基站或小区已经进入节能状态, 0表示该 基站或小区已经从节能状态中恢复。
按照目前 3GPP网管规范对北向接口 IRP操作的定义,可以采用以下 2 种方式来完成节能状态改变通知的操作。
方式 1, IRPAgent在北向接口向 IRPManager发送专用的节能状态改变 通知(例如 NotifyESStateUpdate ), 在所述节能状态改变通知消息中携带基 站标识 (eNBID )或小区标识 (celllD ), 以及节能状态属性的取值(例如 True或 False, 1或 0 )。 IRPManager和 IRPAgent的交互过程如附图 6所示。
方式 2, IRPAgent在北向接口通过通知集成参考点 ( Notifications IRP ) 向 IRPManager发送节能状态改变通知。
作为本发明的一个实施例, IRPManager向 IRPAgent发起的节能管理过 程后, 基站将结合本身的节能操作触发条件组合触发节能操作。 例如:
如果所述基站根据网络管理系统发起的节能使能 /禁止过程为设置节能 生效周期属性, 那么, 在所设置的节能生效周期内, 如果所述基站或所述 基站控制的小区的负载状况低于预先设定的门限值, 则所述基站进行节能 激活操作, 进入节能状态, 如果所述基站或所述基站控制的小区的负载状 况尚未低于预先设定的门限值, 则所述基站不进行节能激活操作, 不进入 节能状态; 或者
如果所述基站或所述基站控制的小区的负载状况上升到高于预先设定 的门限值, 或者所述基站或所述基站控制的小区的节能生效周期到达结束 时间, 则所述基站进行节能恢复操作, 退出节能状态。
另一种实施例,在 IRPManager发起节能激活 /恢复过程后, 不结合自身 的节能操作触发条件, 立即触发所述基站或小区的节能激活 /恢复操作。
综上可知, 本发明实施例提供的基站节能管理方法, 通过集成参考点 管理者 IRPManager向集成参考点代理 IRPAgent发起节能使能 /禁止过程或 节能激活 /恢复过程, 运营商可以在基站级或小区级对基站节能过程进行统 一管理, 增强了原有的基站本身进行节能操作触发判决的可靠性和准确性, 从而为运营商提供全网的基站节能监控、 基站节能策略设置能力, 有利于 主动掌控基站节能操作对网络带来的性能影响。 本发明实施例还提供了一种基站节能方法, 包括基站根据网络管理系 统发起的节能使能 /禁止过程设置节能使能 /禁止属性,和 /或节能生效周期属 性; 或者

( 2 )网络管理系统也可以不事先对某基站或基站控制的小区的节能使 能 /禁止属性进行设置, 而是直接设置该基站或基站控制的小区的节能生效 周期属性; 当所述节能生效周期为有效时间值时, 表示允许对该基站或该 基站控制的小区进行节能操作, 当所述节能生效周期为非有效时间值时, 表示不允许对该基站或该基站控制的小区进行节能操作。
可选地, 当基站接收到网络管理系统发送的节能生效周期后, 将结合 本身的节能操作触发条件判决执行如下的节能激活 /恢复操作:

( 1 ) 当所述属性设置单元 91设置的节能使能 /禁止属性为禁止, 则禁 止设置节能生效周期属性。
( 2 )上述属性设置单元 91还可以不设置节能使能 /禁止属性, 而是通 过节能生效周期属性的设置决定是否对该基站或基站控制的小区进行节能 操作。 具体地, 当所述节能生效周期为有效时间值时, 表示允许对该基站 或该基站控制的小区进行节能操作, 当所述节能生效周期为非有效时间值 时, 表示禁止对该基站或该基站控制的小区进行节能操作。
由上可知, 本发明实施例提供的基站, 可以使运营商可以在基站级或 小区级对象对基站节能过程进行统一管理, 增强了原有的基站本身进行节 能操作触发判决的可靠性和准确性, 从而为运营商提供全网的基站节能监 控、 基站节能策略设置能力, 有利于主动掌控基站节能操作对网络带来的 性能影响。
最后需要说明的有如下三点:
( 1 )上述实施例仅以 LTE系统为例进行介绍, 但本发明实施例提供的 基站节能管理方法和基站节能方法, 不仅适用于 LTE系统的 eNodeB基站, 也同样适用于其他通信系统的基站, 例如: UMTS NodeB或 GSM BTS。
( 2 )在基站节能过程中, 网络管理系统是面向网络全局资源状况或性 能监控状况进行基站节能策略管理协调的参与者, 可以根据运营商的基站 节能策略选择单例或批量的基站进行节能激活或节能恢复操作。
( 3 )网络管理系统对基站节能操作的控制对象粒度应限定在基站级或 小区级, 更细的节能控制对象粒度(如: 信道、 射频模块)可由基站自身 内部实现决定。 本领域技术人员还可以意识到, 结合本文中所公开的实施例描述的各 示例的单元及实现步骤, 能够以电子硬件、 计算机软件或者二者的结合来 实现, 为了清楚地说明硬件和软件的可互换性, 在上述说明中已经按照功 能一般性地描述了各示例的组成及步骤。 这些功能究竟以硬件还是软件方 式来执行, 取决于技术方案的特定应用和设计约束条件。 本领域技术人员 可以对每个特定的应用使用不同方法来实现所描述的功能, 但是这种实现 不应认为超出本发明的范围。
结合本文中所公开的实施例描述的方法步骤, 可以用硬件、 处理器执 行的软件模块, 或者二者的结合来实施。 软件模块可以置于随机存储器
( RAM ), 内存、 只读存储器(ROM )、 电可编程 ROM、 电可擦除可编程 ROM, 寄存器、 硬盘、 可移动磁盘、 CD-ROM、 或任意其它形式的存储介 质中。
上述具体实施例并不用以限制本发明, 对于本技术领域的普通技术人 员来说, 凡在不脱离本发明原理的前提下, 所作的任何修改、 等同替换、 改进等, 均应包含在本发明的保护范围之内。
