Description
一种无线网络实现节能的方法及*** 技术领域
本发明涉及无线通信技术, 尤其涉及一种无线网络实现节能的方法及 ***。 背景技术
随着无线通信技术的发展, 越来越先进的技术大大提升了无线通信的 性能, 而同时各个通信运营商为了满足用户越来越高的需求, 也在不断的 增加自身的网络覆盖以及网络容量, 但是, 随着竟争的激烈, 以及当今世 界越发重视的绿色经济, 给运营商的运营能力提供了很大的挑战, 电信行 业逐渐进入微利阶段。 运营商一方面要不断建站来提升自身的网络性能, 比如网络覆盖和网络容量, 以寻求扩大市场份额和业务种类增收, 而另一 方面还要严格控制运营支出以增加利润。 其中, 在运营商的运营支出中, 有一定比例是出自无线网络的能耗, 而基站作为运营商能源的消耗大户, 是节能的关键。 因此, 如何减少能耗是运营商出于自身利润考虑需要解决 的一个问题, 而且, 无线网络的节能也响应了当前全球的节能减排的呼声。
当前, 第三代合作伙伴计划(3GPP, 3rd Generation Partnership Project ) 的两种无线网络即通用移动通信*** ( UMTS , Universal Mobile Telecommunications System )和长期演进 ( LTE, Long Term Evolution )*** 的网络正处在发展扩张阶段。
图 1为现有 LTE网络架构示意图, 如图 1所示, 由演进全球陆地无线 接入网 ( E-UTRAN, Evolved Universal Terrestrial Radio Access Network ) ^ 演进分组交换中心 ( EPC, Evolved Packet Core )组成, 网络呈现扁平化。 E-UTRAN通过 SI接口与 EPC相连。 其中, E-UTRAN由多个相互连接的
演进基站( eNB , Evolved NodeB )组成 , 各个 eNB之间通过 X2接口连接; EPC由移动性管理实体(MME, Mobility Management Entity )和服务网关 ( S-GW , Serving Gateway )组成。
图 2为 UMTS组成结构示意图, 如图 2所示, UMTS由核心网 (CN, Core Network )和全球陆地无线接入网 ( UTRAN , Universal Terrestrial Radio Access Network )组成, 其中, UTRAN 由无线网络控制器 (RNC , Radio Network Controller )和基站 Node B (或称为节点 B )组成, 两者通过 lub 口连接。 其中 RNC之间可以通过 Iur口互联, 而 RNC与核心网通过 Iu口 连接。
在上述的网络中, 接入网设备的数量是非常庞大的, 因此, 接入网的 节能基本占到了整个网络节能需求的大部分。 为了实现基站节能, 目前主 要是釆用新型节能环保器件和对散热材料进行改进的方式, 以减少基站的 功耗, 同时降低散热带来的功耗。 但是, 这种方式存在如下问题: 釆用这 类器件增加了基站的制造成本, 同时大量的未釆用这类器件的基站达不到 节能的目的。 因此, 当前的节能大多通过小区开 /关来实现。
为了适应无线通信技术发现迅速, 某一局域中, 可能只有 UTRAN 网 络, 也可能只有 E-UTRAN 网络, 但是也有可能多个***网络同时存在即 Inter-RAT场景。 UMTS和 LTE***中的无线网络都通过适时的开 /关小区 ( Cell )来达到节电, 比如: 在 UMTS***中, RNC可以通过小区配置请 求( Cell Configuration Request )消息来通知 Node B下的某个或某些小区进 入 /离开休眠模式(Enter/leave Dormant Mode ), 以使其激活 /去激活节能模 式; 在 LTE***中, 演进基站 eNB下的某个或某些小区可以主动进入节能 模式, 也可以为了减少网络负荷唤醒另一个已进入节能模式的 eNB (或其 下辖的某个小区)。
当前决策某个基站或者基站下的小区进入 /离开节能状态的判断依据主 要是小区的负荷信息, 即一般是当某个基站 (或小区) 的负荷低于预设阔
值时, 该基站(或下辖的某个小区)可以主动进入或被要求进入节能状态。 在 LTE ***中, 邻接基站或小区的负荷信息可以通过资源状态报告 ( Resource Status Report )获得。 但是, 负荷状态不能直接用来衡量能耗, 因为能耗还与其他诸多因素有关, 比如基站所处的状态, 基站相关的制冷 设备(比如空调)等, 因此, 现有通过小区开 /关来实现节能的方式中, 不 能准确掌握无线网络的能耗状况, 从而不能合理地决定哪些基站或小区适 时进入节能状态, 最终不能达到节能的最佳状态。 发明内容
有鉴于此, 本发明的主要目的在于提供一种无线网络实现节能的方法 及***, 能够准确掌握无线网络的能耗状况, 从而合理地决定哪些基站或 小区适时进入节能状态, 最终达到节能的最佳状态。

决策网元可以是操作管理维护 OAM ( Operation Administration Maintenance )。特别地,对于 UMTS***的 UTRAN网络, 决策网元还可以 是 RNC; 对于 LTE***的 E-UTRAN网络, 决策网元还可以是邻接基站; 对于有多个***同时部署的网络场景, 即在某一局域同时有 UMTS和 LTE 等多个网络部署时, 决策网元为自身所在网络中或其它网络中的决策网元, 比如, 在 UMTS***中可以是 RNC , 在 LTE***中可以是演进基站 eNB
等。
本步骤中, 上报过程可以由基站主动发起, 也可以是由决策网元通过 请求上报的方式发起。 其中, 基站主动发起的触发方式也可以是基于时间 触发, 或者根据本基站的能耗低于一定门限触发等方式。 上报釆用的消息 可以利用现有消息, 比如: UTR AN中的审计响应消息 ( Audit Response ) , 或者 E-UTRAN中的资源状态响应消息 ( Resource Status Report ) 消息, 或 者***间的直传消息(比如 RIM ); 上报釆用的消息也可以是使用新增的上 报消息。 为了标识上报网元身份, 在上报消息中还可以包含相应基站或基 站所辖小区的标识信息。
本步骤中, 能耗信息是指基站或基站所辖小区工作消耗的能量信息, 能耗信息代表了基站或基站所辖小区消耗的能量的大小, 能耗信息可以包 括以下一种或多种: 耗电量、 周围环境温度等。 其中:
耗电量, 可以是基站或基站所辖小区的功率(单位: 瓦)或用电量(单 位: 千瓦时)信息, 也可以是基站所处基站室中的部分或所有设备(包括 基站、 射频模块、 其他外设比如制冷设备等) 的耗电功率或用电量。 该功 率信息可以是当前的瞬时功率, 或者是在某段时间内的平均功率或用电量。 在具体上报时, 耗电量可以直接釆用实际的功率值, 也可以上报统一编码 后的指示信息, 比如利用 0~100之间的整数表示, 0表示耗电量低于最小阔 值, 100表示耗电量高于最大阈值, 其他值代表介于两个阈值之间的其他耗 电大小, 或釆用其他表示方式。
周围环境温度, 可以是基站内部重要模块器件的温度信息, 比如 CPU 温度或者射频模块温度等, 也可以是基站室内的某特定观测点的温度信息。 该温度信息可以是当前的瞬时温度, 或者在某段时间内的平均温度值。 在 具体上报时, 温度信息可以直接釆用实际的温度值, 也可以上报统一编码 后的指示信息,比如利用 0~100之间的整数表示, 0表示温度低于最小阔值, 100表示温度高于最大阔值, 其他值代表介于两个阔值之间的其他温度大

能耗信息还可以进一步包括: 各基站或基站所辖小区的射频单元的个 数、 射频模块中功放的个数等信息、 天线个数等其中的一项或多项, 该信 息可以代表基站射频能耗的大小。
步骤 301: 决策网元根据上报的能耗信息确定该基站管辖下的小区状 态。
小区状态包括进入或离开节能状态, 可以是通过小区关闭或开启 ( Switch off/on ), 或者降低 /增加发射功率, 或者关闭 /开启载频, 或者减少 /增加射频天线数目等方法来实现, 以达到节能的目的。
本步骤中, 在决策网元中预先设置有决策策略, 用于综合考虑能耗信 息, 比如分别为各种能耗信息设定权重评定标准等, 比如权重越大代表能 耗越高, 而通过关闭能耗最高的基站下的小区来达到节能目的。 具体的决 策策略很多, 这里并不做限定, 也不用于限定本发明发保护范围。
通过本发明方法, 使得运营商准确掌握了无线网络的能耗状况, 从而 合理地决定哪些基站或小区适时进入节能状态, 最终达到了节能的最佳状 态。 另外运营商也及时获取了各个基站的运行状态, 从而实现了网络参数 配置的灵活调整, 从而优化了设备性能。
针对本发明方法还提供一种无线网络实现节能的***, 如图 4所示, 至少包括基站和决策网元, 其中,
基站, 用于向决策网元上报自身的能耗信息。
决策网元, 用于根据上报的能耗信息确定该基站管辖下的小区状态。 决策网元, 还用于向基站发送上报能耗信息的请求。

比如, 在 UMTS***中可以是 RNC , 在 LTE***中可以是演进基站 eNB 等。
所述基站, 还用于上报小区的无线资源状态信息; 所述决策网元, 具 体用于根据获得的无线资源状态信息和所述能耗信息确定该基站管辖下的 小区状态。
下面结合实施例对本发明方法进行详细描述。 图 5 为本发明实施例中 的网络覆盖示意图, 如图 5所示, 小区 A、 小区 B、 小区 C和小区 D是分 别属于不同的基站的 4个小区, 即分别属于基站八、 基站 B、 基站 C和基 站 D。 以下实施例中以图 5中的网络覆盖为例进行描述。
第一实施例, 以 UTRAN网络为例, 假设基站 A、 基站 B、 基站 C和 基站 D四个基站属于同一个 RNC1管理, 且该 RNC1为决策网元, 包括: 首先, RNC1分别向基站 A、 基站 B、 基站 C和基站 D发送审计请求 ( Audit Request ) 消息, 要求基站上报能耗信息。
接着, 基站 A、 基站 B、 基站 C和基站 D分别将各自基站的能耗信息 通过审计响应( Audit Response )消息上报给 RNC1, 其中, 能耗信息包括: 各个基站的耗电量(假设为各基站在最近单位时间内的平均功率)分别为 2.2kw、 1.0kw、 1.2kw、 1.6kw; 各基站室的环境温度分别为 23摄氏度( °C: )、 26°C、 29 °C、 33 °C ; 以及各基站中的射频天线的个数分别为 4、 2、 4、 8。
最后, RNC1在收到基站 A、 基站 B、 基站 C和基站 D上报的能耗信 息后, 根据综合考虑能耗信息设置的决策策略, 比如分别为各种能量信息 设定权重评定标准: 其中耗电量小于 lkw时权重最低是 0, 每增加 O.lkw 权重增加 1 ; 环境温度低于 20°C时权重最低为 0, 每增加 1 °C权重增加 1 ; 天线个数为 1时权重最低为 0, 每增加 1根天线权重增加 1。 计算各个基站 的权重分别为 18、 7、 14、 26, 其中, 权重越大代表了能耗越高。 显然, 四 个基站中基站 D能耗最高, 因此, RNC1决定通知基站 D下的小区 D关闭, 从而达到节能目的。
第二实施例, 以 E-UTR AN网络为例, 其中基站均为演进基站即 eNB , 且假设决策网元为基站 A, 包括:
首先, 基站 A向演进基站 B、 基站 C和基站 D分别发送资源状态请求 ( Resource Status Request ) 消息, 要求上 4艮基站 B、 基站 C和基站 D下的 能耗信息, 同时要求上报小区的无线资源状态信息。
接着, 如果基站^ 基站 C和基站 D成功发起能耗信息测量, 基站 B、 基站 C和基站 D分别将各自基站的能耗信息通过资源状态响应 (Resource Status Response )消息上报给基站 A, 其中, 能耗信息包括: 各个基站 CPU 的温度信息分别为 36°C、32°C和 30°C ;各个基站的耗电量分别为 lkw、 1.2kw 和 1.3kw; 小区无线资源状态信息中包括: 各个小区下行保证比特率物理资 源利用率( DL GBR PRB usage )为 18、 17、 20 (数值代表利用率的百分比 值)。
最后, 基站 A根据收到的基站:^ 基站 C和基站 D上报的能耗信息, 以及小区下行保证比特率物理资源利用率判断决策各基站的节能状态。 比 如: 分别为各个评判优先级权重评定标准, 资源利用率为 100 时优先级权 重最低为 0, 利用率每减少 1则优先级加 1 ; 耗电量小于 lkw时权重最低是 0, 每增加 0. lkw权重增加 1 ; 环境温度低于 20 °C时权重最低为 0, 每增加 1 °C权重增加 1。 根据上述决策策略计算各个基站的权重分别为 98、 97和 93 , 其中权重越大代表了节能优先级越高。 三个基站中 C能耗最高, 因此, 基站 A通知基站 C下的小区 C关闭, 从而达到节能目的。
第二实施例中, 要求上报小区无线资源状态信息相关内容为现有内容。 第三实施例, 以 E-UTR AN网络为例, 其中基站均为演进基站即 eNB , 决策网元为 OAM, 包括:
基站 A、 基站 B、 基站 C和基站 D分别向 OAM周期性上报各自的能 耗信息; 其中, 能耗信息包括基站的温度信息, 比如基站八、 基站 B、 基站
C和基站 D的温度分别为 50°C:、 32°C、 38°C和 42°C , 其中该温度可以是在
基站设备测得的平均温度;
OAM根据收到的基站八、 基站 B、 基站 C和基站 D上报的能耗信息, 认为基站 A的温度过高, 按照预先设置的决策策略, 通知基站 A下的小区 A减小发射功率。
第四实施例, 以由 UTRAN网络和 E-UTRAN网络组成为例, 其中, 基 站 A为 UTRAN网络中的基站且连接到 RNC2, 且 RNC2为决策网元, 基 站 B、 基站 C和基站 D为 E-UTRAN网络中的 eNB , 大体描述如下:
基站 B、 基站 C和基站 D在每天固定时间 (比如晚上 10点), 通过系 统间的直传 RIM消息分别将各自下的能耗信息上报给 RNC2; 同时基站 A 也将本基站的能耗信息通过新增能耗上报消息上报给 RNC2。 其中基站 B、 基站 C和基站 D的能耗信息包括: 各个基站的耗电量, 分别为 lkw, 1.2kw 和 1.6kw;
RNC2在收到基站 A、 基站 B、 基站 C和基站 D上报的能耗信息后, 假设判断出基站 D的能耗最大, 因此, 通知基站 D下的小区 D关闭, 从而 达到节能目的。
以上所述, 仅为本发明的较佳实施例而已, 并非用于限定本发明的保 护范围, 凡在本发明的精神和原则之内所作的任何修改、 等同替换和改进 等, 均应包含在本发明的保护范围之内。
