2、 RNC使 NodeB需休眠小区上的用户迁移到其他小区， 或者 NodeB迁 移需休眠小区上的用户到其他小区， 保证在进入节能休眠状态的过程中用户 不掉话（线） ；
3、 需休眠小区上的用户迁移到其他小区后， 立即进行休眠， 保证进入节 能休眠状态的过程迅速；
4、 基站的节能控制过程不会导致小区的删除、 重建， 相当于 NodeB 小 区存在 3种状态： 正常态 （解闭塞态） 、 阻塞态、 节能休眠状态。 附图概述
图 1是本发明实施例一的流程图；
图 2是本发明实施例二的流程图；
图 3是本发明实施例三的流程图；
图 4是本发明实施例四的流程图。 本发明的较佳实施方式
在本发明中， 通过 RNC (无线网络控制器）指示 NodeB (节点 B, 基站） 进行节能控制 （通过休眠、 唤醒某些载波等手段）来达到 NodeB节能环保的 目的。
即：
当 NodeB的小区需要休眠时， RNC发送小区休眠的指示给 NodeB, NodeB 休眠所述小区， 进入节能状态；
当 NodeB的小区需要唤醒时， RNC发送小区唤醒的指示给 NodeB, NodeB 唤醒所述小区， 退出节能状态。
所述 RNC发送节能控制指示给 NodeB, 指示 NodeB休眠或唤醒小区， 所述节能控制指示包括小区休眠的指示和小区唤醒的指示；
所述小区休眠的指示包括立即休眠小区的指示和友好休眠小区的指示； 所述小区唤醒的指示包括立即唤醒小区的指示。
其中， 休眠小区可以有两种方式：
方式一， 小区休眠由 RNC进行控制的处理， 具体包括如下步骤：
( 1 ) RNC使 NodeB需休眠小区上的用户迁移到其他小区， 防止用户掉 话， 并控制新接入该本小区上的用户；
比如， RNC控制 NodeB逐步减小需休眠小区的载波的导频信道功率，在 该小区下的用户将因为导频信号的不断减小， 依据现有的移动策略切换到其 他的小区上去， 新接入到该小区上的用户也将被拒绝； 当导频功率达到较小 值后， 在后续的步骤中再将小区的载波的导频信道（发射）功率降为 0或关 断载波， 以保证用户不掉话；
( 2 ) RNC确保小区的所有用户都迁移到其他小区后， RNC发送节能控 制指示 （立即休眠小区）给 NodeB, 指示 NodeB立即休眠小区；
( 3 ) NodeB收到 RNC的节能控制指示 （立即休眠小区）后， 立即休眠 小区 （将小区的载波的导频信道功率降为 0或关断载波） ；
如果处理成功， NodeB返回节能控制成功响应给 RNC;
如果处理失败， NodeB返回节能控制失败响应给 RNC, 其中携带失败原 因 （节能控制失败） ；
NodeB 的闭塞行为 （即休眠小区） 不会再发送闭塞消息 （BLOCK RESOURCE REQUEST )告知 RNC。
方式二， 小区休眠由 NodeB进行控制的处理， 具体包括如下步骤：
( 1 ) RNC发送节能控制指示 （友好休眠小区 )给 NodeB, 指示 NodeB 友好休眠小区；
( 2 ) NodeB收到 RNC的节能控制指示 （友好休眠小区）后， 迁移需休 眠小区上的用户到其他小区， 防止用户掉话， 并控制新接入到本小区上的用 户；
比如， NodeB逐步减小需休眠的小区的载波的导频信道功率， 在该载波 下的用户将因为导频信号的不断减小， 依据现有的移动策略切换到其他的小 区上去， 新接入到本小区上的用户也将被拒绝；
( 3 ) NodeB在确保小区的所有用户都迁移到其他小区后，再休眠该小区 (将小区的载波的导频信道功率降为 0或关断载波） ， 以保证用户不掉话； 如果处理成功， NodeB返回节能控制成功响应给 RNC;
如果处理失败， NodeB返回节能控制失败响应给 RNC, 其中携带失败原 因 （节能控制失败） ；
NodeB 的闭塞行为 （即休眠小区） 不会再发送闭塞消息 （BLOCK RESOURCE REQUEST )告知 RNC。 其中， 唤醒小区具体包括如下步骤：
( 1 ) RNC发送节能控制指示 （立即唤醒小区 )给 NodeB, 指示 NodeB 立即唤醒小区， 将小区的导频信号恢复原来的值；
( 2 ) NodeB收到 RNC的节能控制指示 （立即唤醒小区）后， 重新打开 载波， 将小区的载波的导频信道功率恢复成工作状态值， 即恢复工作；
如果处理成功， NodeB返回节能控制成功响应给 RNC;
如果处理失败， NodeB返回节能控制失败响应给 RNC, 其中携带失败原 因 （节能控制失败） ；
当 NodeB 导频配置恢复时， 不会再发送解闭塞消息 （UNBLOCK
RESOURCE INDICATION )告知 RNC。
这样， 相当于 NodeB小区存在 3种状态： 正常态（解闭塞态）、 阻塞态、 节能休眠状态。 （NBAP协议规定 NodeB可以发起资源闭塞和解闭塞操作， 常见的是 NodeB的网管操作可以人工设置小区的闭塞和解闭塞， 这里的阻塞 态就是指 NodeB发起的闭塞小区操作导致的小区状态）
在宽带码分多址接入 ( Wideband Code Division Multiple Access, 简称 WCDMA ) 系统中， 如果 RNC需要改变 NodeB的小区（Cell )的资源配置时 (例如 Cell载波的导频信道功率（CPICH Power ) 时） ， RNC发送小区重配 请求（ CELL RECONFIGURATION REQUEST )给 NodeB, NodeB处理后， 如果处理成功， 返回小区重配响应 （ CELL RECONFIGURATION RESPONSE );如果处理失败，返回小区重配失败（ CELL RECONFIGURATION FAILURE ) 。
在本发明中， 可以扩展 lub 口小区重配请求消息， 使用该消息携带节能 控制指示： 增加节能控制指示 IE ( Information Element, 信元） ， 在该信元中 写入节能控制指示， 包括 3种指示： 立即休眠小区、 友好休眠小区、 立即唤 醒小区； 扩展 lub 口小区重配失败消息， 使用该消息携带表示节能控制失败 的失败原因： 失败原因 IE中增加 "节能控制失败" 。 涉及对 25.433协议消息的修改如下（粗斜体、带下划线部分为新增部分）: 9.1.27CELL RECONFIGURATION REQUEST (小区重配请求消息）
9.1.27.1 FDD Message (频分双工信息）

也可以新增 Iub 口的节能控制指示消息 （ ENERGY SAVINGS INDICATION ) ,使用该消息携带节能控制指示： 其中指示 IE包括 3种指示： 立即休眠小区、 友好休眠小区、 立即唤醒小区；
并新增 Iub口的节能控制响应消息（ ENERGY SAVINGS RESPONSE ) , 表示节能控制处理成功；新增 Iub口的节能控制失败消息（ ENERGY SAVINGS FAILURE ) , 表示节能控制处理失败。 本发明的基站节能控制的实现系统包括： RNC和 NodeB, 其中， 当 NodeB 的小区需要休眠时， RNC用于发送小区休眠的指示给 NodeB; 当 NodeB 的小区需要唤醒时， RNC 用于发送小区唤醒的指示给 NodeB;
NodeB用于根据 RNC的指示， 休眠或唤醒所述小区。
当小区休眠由 RNC进行控制，所述 RNC用于使 NodeB需休眠小区上的 用户迁移到其他小区， 再发送节能控制指示 （立即休眠小区）给 NodeB, 指 示 NodeB立即休眠小区。 所述 RNC可以通过控制 NodeB逐步减小需休眠小 区的载波的导频信道功率， 使 NodeB需休眠小区上的用户迁移到其他小区。
当小区休眠由 NodeB进行控制的处理， 则所述 RNC用于发送节能控制 指示 （友好休眠小区）给 NodeB, 指示 NodeB友好休眠小区， 所述 NodeB 用于迁移需休眠小区上的用户到其他小区。 所述 NodeB可以通过逐步减小需 休眠的小区的载波的导频信道功率， 迁移需休眠小区上的用户到其他小区。
当 NodeB的小区需要唤醒时， RNC用于发送节能控制指示给 NodeB, 指示 NodeB立即唤醒小区； NodeB用于将小区的载波的导频信道功率恢复成 工作状态值。
