Description

一种节能状态通知方法及演进基站 技术领域
本发明涉及移动通信系统中的节能技术， 尤其涉及一种节能状态通知 方法及演进基站（eNB )。 背景技术
移动通信技术以其开放的网络系统架构得到越来越多的部署和应用， 随着移动通信技术的普及， 以及全球温室效应和气候变化， 网络运营商越 来越关注于移动通信系统的节能技术。 针对节能技术， 基于第三代（3G, 3rd-generation ) 移动通信技术的第三代合作伙伴计划 （3GPP , The 3rd Generation Partnership Project )协议定义了四种小区节能状态： 节能激活、 节能去激活、节能补偿激活和节能补偿去激活。长期演进（LTE, Long Term Evolution )项目是近年来 3GPP启动的新技术研发项目， 在 LTE系统中， 对节能技术进行了标准化， LTE网管通过关闭 eNB或关闭小区等节能措施 降低网络的能耗， 保护环境， 同时降低运营商的运维成本。
目前， LTE系统中实现节能状态管理的方法为： 通过 X2接口信令在进 行节能状态设置的小区及其相邻小区所在的 eNB 间进行指令及通知的交 互， 具体为： eNB根据网络服务信息和节能策略设置小区进入节能激活状 态， 并通知网管及相邻 eNB 该小区进入节能激活状态， 由网管为该处于节 能激活状态的小区选出节能补偿小区， 并向所选节能补偿小区所在的 eNB 发送节能补偿激活指令； 同样， 当 eNB的一个处于节能激活状态的小区要 恢复正常状态时， eNB会通知网管该小区进入节能去激活状态。
但是， eNB目前没有向相邻 eNB提供节能补偿激活和节能补偿去激活 两类通知， 这样， 当某小区 A需要进行负荷均衡或其它服务操作时， 由于 不知道自身的相邻小区处于节能补偿状态， 该小区 A可能会将处于节能补 偿状态的相邻小区作为服务候选小区， 如果最终选中处于节能补偿状态的 小区为小区 A提供服务操作， 则因为所处节能状态原因， 会出现操作无法 正常进行的情况， 或者出现需要先激活选中的小区后才能正常操作的情况， 如此， 会对系统的操作造成一定的影响， 从而降低了系统的节能效率、 系 统的稳定性， 影响用户的使用体验。 发明内容

步驟 102: eNB向相邻 eNB发送自身管理小区的节能状态通知； 这里， 所述发送自身管理小区的节能状态通知为： eNB确认自身管 理的小区中有小区处于节能补偿激活状态， 则向相邻 eNB发送小区处于 节能补偿激活状态的通知； eNB 确认自身管理的小区中有小区处于节能 补偿去激活状态， 则向相邻 eNB发送小区处于节能补偿去激活状态的通 知；
其中， 所述处于节能补偿激活状态的通知包括： 小区标识、 小区所在 eNB标识和通知内容等； 其中， 通知内容为小区已进入节能补偿激活状态； 所述处于节能补偿去激活状态的通知包括： 小区标识、 小区所在 eNB 标识和通知内容等； 其中， 通知内容为小区已进入节能补偿去激活状态； 所述发送指先按照 X2接口信令的格式编写节能状态通知，然后发送所 编写的节能状态通知
图 1所示节能状态通知方法的具体处理过程如图 2所示， 包括以下步 驟：
步驟 201 : eNB实时接收并记录网络服务信息和无线资源信息。
步驟 201之前， 本发明还可以包括下述处理过程： 使用 LTE网管进行 节能策略的设定， 然后网管将所设定的节能策略下发给各个 eNB, 各 eNB 接收并保存节能策略。
步驟 202: eNB周期性查看网络服务信息是否有节能补偿激活指令或节 能补偿去激活指令， 如果有节能补偿激活指令， 则执行步驟 203; 如果有节 能补偿去激活指令， 则执行步驟 205。
具体的， eNB 周期性查看网络服务信息是否有节能补偿激活指令、 节 能补偿去激活指令、 处于节能补偿激活状态的通知、 和 /或处于节能补偿去 激活状态的通知， 如果有节能补偿激活指令， 则执行步驟 203; 如果有节能 补偿去激活指令， 则执行步驟 205; 如果有处于节能补偿激活状态的通知、 和 /或处于节能补偿去激活状态的通知， 则 eNB先提取出通知中的小区、 小 区所在 eNB以及小区节能状态等信息进行记录， 然后返回步驟 201。
这里， 步驟 202所述的节能补偿去激活指令、 节能补偿激活指令、 处 于节能补偿激活状态的通知、 以及处于节能补偿去激活状态的通知有可能 同时存在， 则 eNB会同时执行步驟 203、 步驟 205以及提取出通知中的小 区、 小区所在 eNB以及小区节能状态等信息进行记录的操作。
步驟 203: eNB按照节能补偿激活指令将指令中指定的小区设置为节能 补偿激活状态。
具体的， eNB提取节能补偿激活指令中的小区标识， 按照小区标识找 到指定的小区， 然后 eNB按照节能补偿激活指令的指令内容将指定小区设 置为节能补偿激活状态。
这里， 所述节能补偿激活指令中包括： 小区标识、 小区所在 eNB标识 和指令内容等； 其中， 所述指令内容为将小区设置为节能补偿激活状态。
步驟 204: eNB查找所有相邻的 eNB, 并向相邻 eNB发送本 eNB有小 区处于节能补偿激活状态的通知， 然后返回步驟 201。
步驟 205: eNB按照节能补偿去激活指令将指令中指定的小区设置为节 能补偿去激活状态。
具体的， eNB提取节能补偿去激活指令中的小区标识， 按照小区标识 找到指令指定的小区， 然后 eNB按照节能补偿去激活指令的指令内容将该 小区设置为节能补偿激活状态。
步驟 206: eNB查找所有相邻的 eNB, 并向相邻 eNB发送本 eNB有小 区处于节能补偿激活状态的通知， 然后返回步驟 201。
上述处理过程中， eNB在执行步驟 202的同时， 还会进行是否有小区 需要进入节能激活状态和 /或节能去激活状态的判断和操作 , 包括：
步驟 a: eNB根据节能策略周期性的、利用接收的网络服务信息和无线 资源信息， 判断 eNB管理的小区是否符合进入节能激活状态的条件， 如果 符合则执行步驟 b; 判断 eNB管理的处于节能激活状态的小区是否符合进 入节能去激活状态的条件， 如果符合则执行步驟 d; 如果均不符合则返回步 驟 201 ;
这里， 步驟 a所述的符合进入节能激活状态的条件、 以及符合进入节 能去激活状态的条件的小区有可能同时存在， 这种情况下， eNB 同时执行 步驟 b和步驟 d。
步驟 b: eNB设置符合节能激活状态的条件的小区进入节能激活状态， 然后向相邻 eNB及 LTE网管发送自身有小区已进入节能激活状态的通知。 步驟 c: LTE网管为该进入节能激活状态的小区选择节能补偿小区， 并 向所选节能补偿小区所在的 eNB 发送节能补偿激活指令， 然后执行步驟 201。
步驟 d: eNB设置该小区进入节能去激活状态， 然后向 LTE网管发送 该小区已进入节能去激活状态的通知。
步驟 e: LTE网管收到通知后， 查找为该小区提供节能补偿的小区， 并 向该提供节能补偿的小区所在 eNB发送节能补偿去激活指令， 然后执行步 驟 201。
为实现上述节能状态通知的方法， 如图 3 所示， 本发明还提供了一种 eNB, 该 eNB包括： 节能管理模块 31、 信令交互模块 32; 其中，
节能管理模块 31 , 用于在有小区进入节能补偿激活状态、 和 /或有小区 进入节能补偿去激活状态时， 向信令交互模块 32发送 eNB管理小区的节 能状态通知；
信令交互模块 32, 用于接收节能管理模块 31发送的 eNB管理小区的 节能状态通知， 并将 eNB管理小区的节能状态通知发送给相邻 eNB。
所述节能管理模块 31 , 具体用于从网络服务信息中查找相邻 eNB, 提 取相邻 eNB标识，再连同进入节能补偿激活状态的小区和 /或进入节能补偿 去激活状态的小区标识、 以及节能状态写成小区所处的节能状态通知。
上述 eNB进一步包括： 资源管理模块 33 , 用于接收网络服务信息和无 线资源信息， 并为节能管理模块发送网络服务信息和无线资源信息， 接收 LTE网管下发的节能策略， 然后发送给节能管理模块 31 ; 相应的， 所述节 能管理模块 31 ,还用于在开启后， 周期性的从资源管理模块 33获取网络服 务信息和无线资源信息， 以及接收资源管理模块 33发送的节能策略； 所述节能管理模块 31 , 根据实际情况设置开启情况或由系统提供定时 器来开启。 所述节能管理模块 31 , 还用于根据节能策略， 利用网络服务信息和无 线资源信息判断是否存在节能补偿激活指令， 如果网络服务信息中存在节 能补偿激活指令， 则按照节能补偿激活指令将指定的小区设置为节能补偿 激活状态； 如果网络服务信息中存在节能补偿去激活指令， 则按照节能补 偿去激活指令将指定小区设置为节能补偿去激活状态； 如果网络服务信息 中存在节能补偿状态的通知和 /或节能补偿去激活状态的通知， 则提取出通 知中的相关信息进行记录；
这里， 所述的节能补偿去激活指令、 节能补偿激活指令、 处于节能补 偿激活状态的通知、 以及处于节能补偿去激活状态的通知有可能同时存在， 则节能管理模块 31 同时设置指令中指定的小区为节能补偿激活状态、 和 / 或设置为节能补偿去激活状态， 并提取通知中的相关信息进行记录。
可见， eNB通过使用上述模块可以完成节能补偿信息交互。
此外， 所述节能管理模块 31 , 还用于根据节能策略， 利用接收的网络 服务信息和无线资源信息， 判断是否有小区符合进入节能激活状态的条件， 符合时设置该小区进入节能激活状态， 然后向信令交互模块 32发送已进入 节能激活状态的通知； 并判断是否有小区符合进入节能去激活状态的条件， 符合时设置该小区进入节能去激活状态， 然后向信令交互模块 32发送该小 区已进入节能去激活状态的通知；
相应的， 所述信令交互模块 32,还用于接收节能管理模块 31发送的已 进入节能激活状态的通知， 根据通知编写节能激活状态通知给相邻 eNB以 及 LTE网管，还接收节能管理模块 31发送的已进入节能去激活状态的通知， 才艮据通知编写节能去激活状态的通知网管。
这里 , 所述符合进入节能激活状态的条件及符合进入节能去激活状态 的条件的小区有可能同时存在， 则节能管理模块 31同时设置符合节能激活 状态的条件的小区进入节能激活状态、 以及设置符合进入节能去激活状态 的小区进入节能去激活状态。
应用上述方案， 可以实现小区节能状态在相邻 eNB间互相通知， 这 样， 能够避免由于不清楚相邻 eNB所管理的小区所处的节能状态而导致 的对系统操作的影响， 从而提高系统节能效率并提高系统的稳定性， 提升 用户体险。
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。
