参见图 2, 本实施例中覆盖区域补偿的主要方法流程如下:
步骤 201 : 根据预设的节能补偿策略判断是否满足发起节能补偿过程的触发条件。 步骤 202: 当满足发起节能补偿过程的触发条件时, 第一节点和第二节点中的一个节 点进行节能补偿过程中的节能操作, 另一个节点进行节能补偿过程中的补偿操作。 当不满 足时, 重复步驟 201。
其中, 第一节点为补偿节点, 第二节点为节能节点; 或者, 第一节点为节能节点, 第 二节点为补偿节点。 并且, 步骤 201可以由补偿节点或节能节点执行, 还可以有第三方的 OAM执行。 以及, 补偿节点和节能节点可以通过多种方式触发和协商节能补偿操作。 本 实施例中补偿节点采用节能补偿策略中的补偿策略, 节能节点采用节能补偿策略中的节能 策略。 下面通过几个实施例来详细介绍实现过程。
参见图 3, 本实施例中补偿节点发起节能补偿的强制过程的方法流程如下: 步骤 301 : 补偿节点根据预设的补偿策略确定需要发起节能补偿过程。 预设的补偿策 略可以有多种, 如到达预设的时间点, 例如晚上 11点。 还可以有其它的补偿策略, 此处不 一一赘述, 任何需要发起节能补偿过程的补偿策略均适用于本实施例。 其中, 补偿策略可 以预先由 OAM ( Operations,Administration and Maintenance, 运行、 管理和维护)实体装置 配置, 也可能在小区间交互。
步骤 302: 补偿节点向节能节点发送补偿请求, 以通知节能节点关闭。 该补偿请求可 具体为小区补偿指示 ( CELL COMPENSATION INDICATION )。 小区补偿指示携带有需关 闭的目标小区的标识, 还可以包括目标小区关闭的最小时长, 也就是说目标小区要在达到 该时长后完成关闭, 关闭时间不要低于该时长, 以便补偿节点有足够的时间覆盖到目标小 区, 减少或避免覆盖空洞。 补偿节点可以同时向相邻的所有节能节点发送小区补偿指示, 则小区补偿指示携带相邻的所有节能节点下的小区标识。 或者, 补偿节点分别向相邻的所 有节能节点发送小区补偿指示, 则针对每个节能节点的小区补偿指示携带该节能节点下的 小区标识。
步骤 303: 补偿节点扩大覆盖范围。 具体操作如: 提高发射功率, 调整天线倾角等。 步驟 304: 补偿节点针对扩大后的小区, 与新的相邻小区进行交互, 收集新相邻小区 的 RLF等相关信息, 以便进一步调整发射功率, 优化覆盖区域。
步骤 305: 节能节点收到补偿请求后, 将小区内用户切换到补偿节点下的小区。 如果 节能节点下有用户接入, 则执行该过程, 如果没有, 可跳过此步骤。
步骤 306: 节能节点进入节能状态, 及进行关闭操作。 关闭操作有多种, 如关闭发射 等。 较佳的, 节能节点仅保留探测功能, 以便接收离开节能状态的指示。
其中, 步骤 303和 304相当于步骤 305和 306是两个独立的过程, 可同步进行。 本实施例中如果补偿节点和节能节点间有 X2接口,则补偿节点可以通过 X2接口向节 能节点发送小区补偿指示, 该小区补偿指示的结构实例参见表 1所示。 如果补偿节点和节 能节点间没有 X2接口, 或者补偿节点和节能节点间属于 inter-RAT场景, 则需要由核心网 ( CN )中的设备将小区补偿指示转发给节能节点, 此时的小区补偿指示的结构实例参见表
2所示, 核心网中的设备直接透传小区补偿指示即可。 表 1

参见图 4 , 本实施例中补偿节点发起节能补偿的一次协商过程的方法流程如下: 步骤 401 : 补偿节点根据预设的补偿策略确定需要发起节能补偿过程。
步驟 402: 补偿节点向节能节点发送补偿请求, 以通知节能节点关闭。 该补偿请求可 具体为节能请求或小区补偿请求 ( CELL COMPENSATION REQUEST )。 节能请求或小区 补偿请求携带有需关闭的目标小区的标识, 还可以包括目标小区关闭的最小时长和与扩大 覆盖有关的信息。 扩大覆盖有关的信息可以有多种, 例如包括补偿节点的最大覆盖半径、 最大发射功率、 当前负荷信息和剩余可用的负荷信息等。 其中, 现有技术中的节能请求应 用于重叠覆盖场景, 仅指示目标小区关闭, 而补偿节点不进行补偿。 本实施例中将节能请 求应用到单层覆盖的场景, 不仅指示目标小区关闭, 补偿节点还需要对目标小区进行覆盖 补偿。
补偿节点可以同时向相邻的所有节能节点发送小区补偿请求, 则小区补偿请求携带相 邻的所有节能节点下的小区标识。 或者, 补偿节点分别向相邻的所有节能节点发送小区补 偿请求, 则针对每个节能节点的小区补偿请求携带该节能节点下的小区标识。
步骤 403 : 节能节点根据本地节能策略和收到的与扩大覆盖有关的信息, 判断是否同 意节能, 若是, 则继续步骤 404 , 否则继续步驟 407。 其中, 节能策略可以预先由 OAM配 置, 也可能在小区间交互。
步骤 404: 节能节点返回接受消息, 表示同意进行节能操作。 该接受消息可具体为小 区补偿响应( CELL COMPENSATION RESPONSE )。 小区补偿响应包括接受节能的小区标 识, 也就是说未携带的小区标识所对应的小区均不接受节能操作, 因此下面返回失败消息 中可以不携带小区标识。
步骤 405 : 节能节点在同意节能后, 将小区内用户切换到补偿节点下的小区。 如果节 能节点下有用户接入, 则执行该过程, 如果没有, 可跳过此步骤。
步骤 406: 节能节点进入节能状态, 及进行关闭操作。 关闭操作有多种, 如关闭发射 等。 较佳的, 节能节点仅保留探测功能, 以便接收离开节能状态的指示。
步骤 407: 节能节点返回失败消息, 表示拒绝进行节能操作。 该失败消息可具体为小 区补偿失败( CELL COMPENSATION FAILURE )。 小区补偿失败可携带有表示拒绝节能操 作的原因的指示信息。
步骤 408: 补偿节点收到接受消息后, 扩大覆盖范围。
步驟 409: 补偿节点针对扩大后的小区, 与新的相邻小区进行交互, 收集新相邻小区 的 RLF等相关信息, 以便进一步调整发射功率, 优化覆盖区域。
步驟 410: 补偿节点收到失败消息后, 维持现状。
本实施例中如果补偿节点和节能节点间有 X2接口, 则补偿节点与节能节点交互的消 息可以通过 X2接口直接传输, 此时该小区补偿请求的结构实例参见表 3所示, 小区补偿 响应的结构实例参见表 4所示, 小区补偿失败的结构实例参见表 5所示。 如果补偿节点和 节能节点间没有 X2接口, 或者补偿节点和节能节点间属于 inter-RAT场景, 则需要由核心 网(CN )中的设备透传补偿节点与节能节点间的消息, 此时的小区补偿请求的结构实例参 见表 6所示, 小区补偿响应的结构实例参见表 7所示, 小区补偿失败的结构实例参见表 8 所示。

步骤 813: 节能节点收到失败消息后, 维持现状。
在需要进行节能补偿操作时, 发起节能补偿操作的设备不限于补偿节点和节能节点, 还可以由第三方设备发起操作, 例如由 0 AM实体发起 , 具体过程参见下面的实施例。
参见图 9, 本实施例中 OAM发起节能补偿的强制过程的方法流程如下:
步驟 901 : OAM收集补偿节点和节能节点的覆盖信息和负荷信息等。 OAM可以搜集 任何与节能补偿有关的信息, 此处只是举例。 该步骤可以周期或定时进行, 或在某些触发 条件下进行。
步驟 902: OAM根据预设的节能补偿策略确定需要发起节能补偿过程。 预设的节能补 偿策略可以包括图 3-图 5中补偿节点的补偿策略和 /或图 6-图 8中节能节点的节能策略等。
步驟 903: OAM动态触发激活补偿节点的补偿状态和节能节点的节能状态。 OAM可 以具体通过向补偿节点和节能节点发送补偿请求的方式触发补偿状态和节能状态。 补偿请 求可以具体为小区补偿指示或其它配置消息。
步驟 904: 节能节点受触发后, 将小区内用户切换到补偿节点下的小区。 如果节能节 点下有用户接入, 则执行该过程, 如果没有, 可跳过此步驟。
步驟 905: 节能节点进入节能状态, 及进行关闭操作。 关闭操作有多种, 如关闭发射 等。 较佳的, 节能节点仅保留探测功能, 以便接收离开节能状态的指示。 以及, 为了减少 或避免出现覆盖空洞, 节能节点在受触发后等待一段时间, 该等待的时长达到预设的目标 小区关闭的最小时长时进行关闭操作。
步骤 906: 补偿节点受触发后扩大覆盖范围。 具体操作如: 提高发射功率, 调整天线 倾角等。
步骤 907: 补偿节点针对扩大后的小区, 与新的相邻小区进行交互, 收集新相邻小区 的 RLF等相关信息, 以便进一步调整发射功率, 优化覆盖区域。 其中, 步驟 904和 905可以与步骤 906和 907同步进行。
参见图 10, 本实施例中 OAM预配置节能补偿策略后自动发起节能补偿过程的方法流 程如下:
步驟 1001 : OAM将时间策略配置到补偿节点和节能节点。 时间策略可以是定时的, 也可以是周期的。 定时的时间策略例如, 补偿节点进入 /离开补偿状态 3 小时后再次离开 / 进入, 同时相关节能节点关闭 /开启 3 小时后开启 /关闭。 周期的时间策略例如, 补偿节点 进入 /离开补偿状态的时间段为 0:00 ~ 7:00,同时相关节能节点进入 /离开节能状态的时间段 可以设置为相同的 0:00 - 7:00。 本实施例中可以将时间策略看作是节能补偿策略的一种或 一部分。
经过一次时间策略的配置后, 下面的步骤可重复执行。
步驟 1002: 节能节点在满足时间策略后, 将小区内用户切换到补偿节点下的小区。 如 果节能节点下有用户接入, 则执行该过程, 如果没有, 可跳过此步驟。
步骤 1003 : 节能节点进入节能状态, 及进行关闭操作。 关闭操作有多种, 如关闭发射 等。 较佳的, 节能节点仅保留探测功能, 以便接收离开节能状态的指示。 以及, 为了减少 或避免出现覆盖空洞, 节能节点在满足时间策略后等待一段时间, 该等待的时长达到预设 的目标小区关闭的最小时长时进行关闭操作。
步骤 1004: 补偿节点在满足时间策略后扩大覆盖范围。 具体操作如: 提高发射功率, 调整天线倾角等。
步驟 1005: 补偿节点针对扩大后的小区, 与新的相邻小区进行交互, 收集新相邻小区 的 RLF等相关信息, 以便进一步调整发射功率, 优化覆盖区域。
以上实施例实现了小区或节点的节能补偿, 节约了能源和减少了辐射。 但是在用户或 数据量增加时, 补偿节点可能无法满足需求, 此时需要开启节能节点, 以便提供较好的通 信服务。 下面针对覆盖恢复过程进行介绍。
参见图 11, 本实施例中覆盖区域恢复的主要方法流程如下:
步驟 1101 : 根据预设的节能补偿恢复策略判断是否满足发起覆盖恢复过程的触发条 件。
步骤 1102: 当满足发起节能补偿过程的触发条件时, 第一节点和第二节点中的一个节 点进行覆盖恢复过程中的节能恢复操作, 另一个节点进行覆盖恢复过程中的补偿恢复操 作。 当不满足时, 重复步驟 1101。
其中, 第一节点为补偿节点, 第二节点为节能节点; 或者, 第一节点为节能节点, 第 二节点为补偿节点。与覆盖区域补偿过程类似,步骤 1101可以由补偿节点或节能节点执行, 还可以有第三方的 OAM执行。 以及, 补偿节点和节能节点可以通过多种方式触发和协商 覆盖恢复操作。 本实施例中补偿节点采用节能补偿恢复策略中的补偿恢复策略, 节能节点 采用节能补偿恢复策略中的节能恢复策略。 下面通过几个实施例来详细介绍实现过程。 参见图 12, 本实施例中补偿节点发起覆盖恢复的强制过程的方法流程如下: 步骤 1201 : 补偿节点根据预设的补偿恢复策略确定需要发起覆盖恢复过程。 预设的补 偿恢复策略可以有多种, 如到达预设的时间点, 例如早上 7点。 还可以有其它的补偿恢复 策略, 此处不一一赘述, 任何需要发起覆盖恢复过程的补偿恢复策略均适用于本实施例。 其中, 补偿恢复策略可以预先由 OAM实体配置, 也可能在小区间交互。
步骤 1202: 补偿节点向节能节点发送去补偿请求, 以通知节能节点开启。 该去补偿请 求可具体为小区去补偿指示( CELL DECOMPENSATION INDICATION )。 小区去补偿指示 携带有请求开启的目标小区的标识, 还可以包括目标小区开启的最大时长, 也就是说目标 小区要在该时长内完成开启, 开启时间不超过该时长, 以便在补偿节点缩小覆盖范围时节 能节点覆盖到目标小区, 减少或避免覆盖空洞。 补偿节点可以同时向相邻的所有节能节点 发送小区去补偿指示, 则小区去补偿指示携带相邻的所有节能节点下的小区标识。 或者, ^卜偿节点分别向相邻的所有节能节点发送小区去 卜偿指示, 则针对每个节能节点的小区去 补偿指示携带该节能节点下的小区标识。
步骤 1203 : 补偿节点切换用户到开启的节能小区。 如果补偿节点下有用户需要切换, 则执行该过程, 如果没有, 可跳过此步驟。 用户是否需要切换, 可参见通信协议中关于切 换判决的规定。
步骤 1204: 补偿节点离开补偿状态, 缩小覆盖范围。 具体操作如: 降低发射功率, 调 整天线倾角等。 补偿节点可以是逐步切换用户, 并逐步缩小覆盖范围。
步骤 1205: 补偿节点针对缩小后的小区, 与新的相邻小区进行交互, 收集新相邻小区 的 RLF等相关信息, 以便进一步调整发射功率, 优化覆盖区域。
步骤 1206: 节能节点收到去补偿请求后, 进行开启操作, 打开节点下需开启小区的所 有功能。
步驟 1207: 节能节点接收切换过来的用户。
本实施例中如果补偿节点和节能节点间有 X2接口,则补偿节点可以通过 X2接口向节 能节点发送小区去补偿指示, 该小区去补偿指示的结构实例参见表 9所示。 如果补偿节点 和节能节点间没有 X2接口, 或者补偿节点和节能节点间属于 inter- AT场景, 则需要由核 心网 (CN )中的设备将小区去补偿指示转发给节能节点, 此时的小区去补偿指示的结构实 例参见表 10所示, 核心网中的设备直接透传小区去补偿指示即可。 表 9

补偿节点可以同时向相邻的所有节能节点发送小区去补偿请求, 则小区去补偿请求携 带相邻的所有节能节点下的小区标识。 或者, 补偿节点分别向相邻的所有节能节点发送小 区去补偿请求, 则针对每个节能节点的小区去补偿请求携带该节能节点下的小区标识。
步骤 1303 : 节能节点根据本地的去节能策略和收到的与缩小覆盖有关的信息, 判断是 否同意恢复, 若是, 则继续步骤 1304, 否则继续步骤 1310。 其中, 去节能策略可以预先 由 OAM配置, 也可能在小区间交互。 去节能策略有多种, 例如只要收到小区去补偿请求 便同意恢复; 或者在满足已配置的时间点时同意恢复等。
步骤 1304: 节能节点返回接受消息, 表示同意进行恢复操作。 该接受消息可具体为小 区去补偿响应 ( CELL DECOMPENSATION RESPONSE )。 小区去补偿响应包括接受开启 的小区标识, 也就是说未携带的小区标识所对应的小区均不接受恢复操作, 因此下面返回 失败消息中可以不携带小区标识。
步 1305: 节能节点在同意恢复后, 离开节能状态, 进行开启操作, 恢复接受开启的 小区的服务。
步骤 1306: 补偿节点收到接受消息后, 切换用户到开启的节能小区。 如果补偿节点下 有用户需要切换, 则执行该过程, 如果没有, 可跳过此步驟。 用户是否需要切换, 可参见 通信协议中关于切换判决的规定。
