Description

一种节能方法及设备 本申请要求于 2010年 4 月 29 日提交中国专利局, 申请号为 201010163089.5 , 发明名称为 "一种节能方法及设备" 的中国专利申 请的优先权, 其全部内容通过引用结合在本申请中。 技术领域
本发明涉及移动通信技术领域, 特别是涉及一种节能方法及设 备。 背景技术
随着科技的进步和经济的发展,保护环境和应对气候变化成为全 人类面临的巨大挑战。 在电信行业, 随着能源消耗的增长, 更多的运 营商开始越来越多地关注自身的社会责任并考虑由于能源价格上涨 而增高的运营成本。
目前, 移动通信网络的节能途径主要包括: 在保证覆盖、 容量、 服务质量不受影响的前提下, 优化站址的数量; 寻找有效的提高能源 利用率和降低设备功耗的方法; 研究开发可持续能源(风能、 太阳能 等)。
对于针对高峰期需求的 RAN ( Radio Access Network, 无线接入 网)侧设备而言,如果在一个三扇区的小区,每个扇区有 4个收发机, 则 12个收发机始终处于激活状态; 而在引入能源控制机制后, 每一 个扇区在业务低峰期(比如深夜)只需要保持一个收发机处于待机状 态就可以满足业务需求。 如果所有的 eNB ( Evolved Node B , 演进型 节点 B )都能够使用上述节能策略, 可以在不影响服务质量的前提下 节省大量的能源。
对于自优化网络而言, 节能实体可以包括以下三种结构: 分布式 架构, 网元收集必要的信息进行自优化过程, 不需 OAM ( Operation Administration Maintenance , 操作管理维护) 系统的参与; 集中式架 构, OAM系统从网元收集信息触发节能算法, 然后决定网元的后续 动作; 混合式结构, 混合使用上述分布式架构和集中式架构。
现有的通信系统中提出了一种 ESM( Energy Saving Management, 节能管理) 方案, 以提高整个或部分网络的资源利用率。 ESM通过 从网络收集和评估相关信息, 发起适当的动作来调整网络配置, 从而 满足服务需求。 ESM 方案可以包含以下两个基本过程: 节能激活, 通过关闭 eNB的小区或限制使用部分物理资源达到节省能源的目的, 相应的 eNB进入节能状态; 节能去激活, 开启被关闭的小区或恢复 被限制的物理资源的使用, 满足增长的业务需求和 Qos ( Quality of Service, 服务质量) 需求, 相应的 eNB 小区从节能激活状态恢复至 正常状态。 其中, 节能的动作包含: 关闭 /打开小区、 关闭 /打开载波、 关闭 /打开收发机、 关闭 /打开 HeNB ( Home Evolved Node B , 家庭演 进型节点 B )等。 当某个网元进入 ESM状态后, 周围处于正常工作 的网元就会进入节能补偿激活状态,通过扩大覆盖范围等方法补偿进 入节能状态的小区的节能业务损失。
发明人在实现本发明的过程中, 发现现有技术至少存在如下问 题:
目前, 只有 LTE ( Long Term Evolution , 长期演进 ) 系统中有相 应的节能方案和流程, 且 LTE系统中只有 Χ2接口支持节能方案。 而 在如图 1所示的 LTE-A( LTE- Advanced,高级长期演进)、 LTE、 UMTS ( Universal Mobile Telecommunications System, 通用移动通信系统 ) 和 GSM ( Global System for Mobile Communications , 全球移动通信系 统)共存的异系统网络中, 由于该网络包括 SI , Iub, Iu, Abis, A/Gb, Iur-g 等接口, 目前的节能方案还不完善, 对于异系统间重复覆盖或 非重叠覆盖的场景均无法实现节能功能。 发明内容

本发明实施例针对节能的需求,提供了一种异系统网络中利用网 络节点自身的负荷信息进行节能的方案, 采用分布式节能架构, 可应 用于包括 LTE、 UMTS, GSM等各种异系统间重叠覆盖或非重叠覆盖 的场景, 并可进一步应用于 LTE- A系统。
具体地, 通过异系统的网络节点间交互小区负荷信息, 网络节点 可以结合自身以及相邻网络节点的负荷情况,根据 ESM算法和策略, 判决自身所管辖的小区 /载波 /收发机进入节能状态(节能激活 ), 并通 过节能状态指示信息将节能小区的 ESM 状态通知该节能小区的邻 区。 节能小区离开节能状态(节能去激活)可以是通过相邻网络节点 的唤醒实现的。 实施以上 ESM过程也可以通过在切换过程中携带节 能指示或将切换原因值设置为节能的方式实现。
通过异系统的网络节点间交互小区负荷信息, 网络节点也可以结 合自身以及相邻网络节点的负荷情况, 根据 ESM算法和策略, 判决 并允许对相邻网络节点所管辖的小区 /载波 /收发机实施 ESM过程,向 目标小区发送节能状态变更指示, 允许目标小区改变节能状态。相邻 网络节点收到节能状态变更指示后, 结合自身的 ESM算法响应该指 示, 可以命令目标小区直接改变节能状态, 或者对该指示进行反馈, 返回是否改变节能状态的指示。 如果目标小区成功改变节能状态, 相 邻网络节点根据获得的网络拓朴结构,通知其邻区该目标小区的 ESM 状态; 如果目标小区没有成功改变节能状态, 则保持原始配置不变。
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, 显然, 所描述的实施例是本发明一部分实 施例, 而不是全部的实施例。 基于本发明中的实施例, 本领域普通技 术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属 于本发明保护的范围。

步骤 201 , 第一网络节点获取与自身相邻的第二网络节点的负荷 信息, 根据自身的负荷信息和第二网络节点的负荷信息进入节能状 态。
具体地,第一网络节点可以向所述第二网络节点发送负荷信息传 递请求消息, 并接收第二网络节点返回的负荷信息传递应答消息, 通 过请求和应答消息获取第二网络节点的负荷信息;第一网络节点也可 以接收来自第二网络节点的负荷信息传递请求消息,获取请求消息中 携带的第二网络节点的负荷信息。 其中, 负荷信息包括以下内容中的 至少一项: 硬件负荷指示信息、 S1 接口传输网络层负荷指示信息、 无线资源状态信息、 上行小区容量信息和下行小区容量信息。
步骤 202, 第一网络节点向与自身相邻的第三网络节点发送节能 状态指示信息,通过该节能状态指示信息将自身进入节能状态的信息 通知第三网络节点。
其中, 第二网络节点与第三网络节点可以为同一节点。 节能状态 指示信息包括以下内容中的至少一项: 源基站标识、 源小区标识、 目 标基站标识、 目标小区标识、 路由信息、 节能指令和切换原因。 第一 网络节点通过节能状态指示信息将自身进入节能状态的信息通知第 三网络节点之后,第三网络节点根据该节能状态指示信息进入节能补 偿状态。第一网络节点根据自身的负荷信息和第二网络节点的负荷信 息进入节能状态之后, 还可以获取网络拓朴信息, 根据所述网络拓朴 信息确定是否需要向所述第三网络节点发送节能状态指示信息。
此外,第三网络节点根据自身的负荷信息和相邻网络节点的负荷 信息, 判决第一网络节点离开节能状态, 并向第一网络节点发送节能 去激活指示信息; 第一网络节点接收该节能去激活指示信息, 根据该 节能去激活指示信息离开节能状态。 其中, 节能去激活指示信息包括 以下内容中的至少一项: 源基站标识、 源小区标识、 目标基站标识、 目标小区标识、 路由信息、 节能指令和切换原因。 第一网络节点根据 节能去激活消息离开节能状态之后,还可以向第三网络节点发送节能 状态指示信息,通过该节能状态指示信息将自身离开节能状态的信息 通知第三网络节点;第三网络节点根据该节能状态指示信息离开节能 补偿状态。
本发明实施例的技术方案具有以下优点,提供了异系统通信网络 中的节能流程, 通过算法策略和信令流程实现 ESM过程, 采用分布 式节能架构, 优化了整个网络的资源利用率。
如图 3所示, 为本发明实施例二中的一种节能方法流程图, 包括 以下步骤:
步骤 301 , 异系统的 RAN节点间传递小区负荷信息。
具体地, 对于 LTE系统和 UMTS系统而言, 由于系统间没有直 接的接口, 可以通过 S1接口、 Iu接口和 lub接口共同完成对节能的 控制和实现。 同样地, 对于 LTE 系统和 GSM 系统而言, 可以通过 S1接口、 Iu(A/Gb)和 Abis接口共同完成对节能的控制和实现。
异系统的 RAN 节点间可以通过 S1 接口和 Iu 接口的 RIM ( Information Exchange Initiation, 信息交换初始)过程传递小区负荷 以及节能状态指示等信息。 在 S1 接口上, 可以通过 MME Direct Information Transfer (移动管理实体直接信息传输) 和 eNB Direct Information Transfer ( eNB直接信息传输 )过程来实现的; 在 Iu接口 上, 可以通过 Direct Information Transfer过程来实现的, 核心网节点 透传该信息。 考虑到多系统以及后续系统演进, 也可以采用其他的接 口消息传递节能状态指示信息以及小区负荷信息。传递小区负荷信息 可以通过请求和应答的方式,也可以通过在请求消息中携带负荷信息 的方式。
其中, 异系统基站间交互的负荷信息包括如表 1所示的列表。

具体地, 为了不影响节能后的覆盖问题, 当节能小区进入节能状 态, 网络节点可以通过 ANR ( Automatic Neighbor Relation , 自动邻 居关系) 获得网络拓朴结构信息, 对于异系统重叠覆盖和 HCS ( Hierarchical Cell Structure, 分层小区结构) 的场景, 可以不需要邻 区进行节能补偿操作, 只需要通知自身的 ESM状态; 对于异系统相 邻关系的场景,节能小区需要通知该节能小区的邻区进入节能补偿状 态。
其中, 节能状态指示信息包括如表 2所示的列表。

步骤 305 ,第二网络节点结合自身以及相邻网络节点的负荷情况, 根据 ESM算法和策略, 判决第一网络节点离开节能状态。
具体地, 网络节点离开节能状态, 包括: 网络节点所管辖的小区 /载波 /收发机离开节能状态, 即节能去激活。
步骤 306, 第二网络节点向第一网络节点的目标小区发送节能去 激活指示信息, 唤醒目标小区离开节能状态。

以下将结合异系统的各种场景,对上述实施例中的节能方法进行 详细、 具体的描述。
对于 LTE系统而言, 网络节点为 eNB, 与其相连的核心网节点 为 MME; 对于 UMTS 系统, 网络节点为 RNC ( Radio Network Controller , 无线网络控制器), 与其相连的核心网节点为 SGSN ( Serving GPRS Support Node, 服务通用分组无线业务支撑节点;); 对于 GSM系统而言, 网络节点为 BSC ( Base Station Controller,基站 控制器), 与其相连的核心网节点为 SGSN。 本发明实施例中的第一网络节点为 LTE系统的 eNB时, 第二网 络节点可以为 UMTS系统的 RNC , eNB和 RNC之间的消息通过 MME 和 SGSN透传。 当上述第一网络节点为 GSM系统的 BSC时,上述第 二网络节点可以为 LTE系统的 eNB, BSC和 eNB之间的消息通过 MME和 SGSN透传。 MME和 SGSN设备用于解析消息中的路由信 息, 透传给目标节点。
其中, eNB可以通过 RIM过程向 RNC或 BSC传送自身的小区 负荷信息, 或者通过 RIM过程向 RNC或 BSC请求负荷信息, 并在 该消息中携带小区负荷信息。 eNB收到 RNC或 BSC发送过来的小区 ESM状态改变信息后, eNB的小区可以根据该信息进入 /离开节能补 偿状态。 eNB可以结合自身以及相邻的 RNC或 BSC的负荷情况,根 据 ESM算法,判决 RNC或 BSC所管辖的某小区离开节能状态, eNB 向 RNC或 BSC的目标小区发送节能去激活指示信息,唤醒其离开节 能状态。

异系统的 RAN节点间可以通过 Iur-g接口上的 RIM过程传递小 区负荷以及节能状态指示等信息。其中,对于 Iur-g接口, Information type (信息类型 ) 只能设置为 Cell Capacity Class (小区容量等级), 即在 Iur-g接口上只交换小区上下行容量信息。 考虑到多系统以及后 续系统演进,也有可能采用其他的接口消息传递节能状态指示信息以 及小区负荷信息。传递小区负荷信息可以通过请求和应答的方式, 也 可以通过在请求消息中携带负荷信息的方式。
本发明实施例中, 还可以通过在切换过程中携带节能指示 IE的 方式进行相关的节能操作。 具体地, 网络节点可以通过在切换过程中 携带节能指示信息,指示目标小区进入节能状态或者唤醒相邻网络节 点的目标小区离开节能状态。在切换过程中携带的节能指示包括以下 列表, 相应的信息修改如表 3所示。
