具体实施方式
本发明实施例提供一种降低基站系统能耗的方法和装置， 能够节 约基站系统的能耗。
下面结合附图对本发明实施例做详细描述。
实施例一
本实施例提供一种降低基站系统能耗的方法， 如图 1 所示， 该方 法包括：
步骤 101、 获取上一周期内实际用户数量小于用户数门限值和 /或 吞吐量小于吞吐量门限值的时间段， 所述时间段至少包括第一子时间 段，所述用户数门限值小于或等于所述基站系统开启一组发射通道时可 承载的最大用户数量，所述吞吐量门限值小于或等于所述基站系统开启 一组发射通道时可承载的最大吞吐量。
本实施例中的周期可以是指人为设定的时间段， 例如， 周期可以 为一天或者一周或者一个月。
一周的七天中， 由于各种因素的影响， 每天的业务量都是不同的， 且存在明显的差距。 研究发现， 每周的同一天内， 如两周前的星期一和 一周前的星期一内， 业务量是基本稳定的， 差距很小。 因此， 作为其中 一种优选实施方式， 本实施例选取一周七天作为一个周期， 即选取上周 的同一天作为本周相应的这一天的参考，并计算上周七天内实际用户数 量小于或等于用户数门限值和 /或吞吐量小于或等于吞吐量门限值的时 间段， 我们称 "用户数量小于用户数门限值和 /或吞吐量小于吞吐量门 限值的时间段" 为 "空闲时段" 。
在确定 "空闲时段" 时， 可只参考用户数门限值或者只参考吞吐 量门限值。
优选的， 为了更准确的得到 "空闲时段" ， 本实施例同时参考用 户数门限值和吞吐量门限值， 即将 "用户数量和吞吐量均小于用户数门 限值和吞吐量门限值的时间段"作为 "空闲时段" ， 举例来说， 经计算，
上星期一的凌晨 2:00 〜 6:00和上午 9:00 〜 1 1 :00内， 用户数量和吞吐量 均小于用户数门限值和吞吐量门限值， 因此， 凌晨 2:00 〜 6:00和上午 9:00 〜 1 1 :00为上星期一的 "空闲时段" ， 可以将 2:00 〜 6:00称为第一 子时间段， 将 9:00 〜 1 1 :00称为第二子时间段。
可选地， 为了更精确的计算出 "空闲时段" ， 防止因偶然因素带 来的误差， 还可以进一步计算两周前、 三周前的星期一的业务量， 并取 三者的平均值。
如图 4所示， MIMO 系统通常将无线网络信号通过多个天线 3进 行同步收发， 以提高数据传输的速率。每个天线 3至少与一个发射通道 或接收通道相连接。
进一步的， 本实施例的方法还包括： 将基站系统的发射通道平均 分为至少包括第一组发射通道和第二组发射通道的若干组发射通道。作 为本发明的其中一种实施方式，本实施例将基站系统的所有发射通道平 均分为 4组， 如图 4所示， 4组发射通道分别为： 第一组发射通道 4、 第二组发射通道 5、 第三组发射通道 6、 第四组发射通道 7 , 每组发射 通道包括至少一个发射通道 1 , 其中， 每组发射通道的数量可根据各个 地区业务量等情况的不同进行选取， 举例来说， 某地区在一天 24时内 的平均业务量较大， 即基站系统收发的数据较多， 因此， 可以将 3-6个 发射通道分成一组。
此外， 需要说明的是， 本实施例中基站系统所有发射通道所分成 的组数需大于等于 2。
作为本发明的一种实施方式， 在已完成分组的基础上， 计算仅开 启一组发射通道时，如仅开启第一组发射通道 4时，基站系统可承载的 最大用户数量和最大吞吐量， 分别作为用户数门限值和吞吐量门限值。 其中， 吞吐量是指基站系统接收和发射的数据量。
考虑到基站系统仅开启一组发射通道可承载的最大用户数量和最 大吞吐量会因为一些不确定的因素，如天气的变化、基站系统的元器件 老化等而发生改变。 因此， 在计算出基站系统仅开启一组发射通道可承 载的最大用户数量的用户数量门限值和可承载的最大吞吐量的吞吐量 门限值后，还需要对任意一组发射通道，如第一组发射通道 4的性能进 行测试，看基站系统仅开启该组发射通道时能够承载的最大用户数量和 最大吞吐量是否分别与上述计算出的用户数量门限值和吞吐量的门限 值相匹配， 如果不匹配的话， 可以根据测试结果对计算得到的用户数量 门限值和吞吐量门限值作适当的调整，以使基站系统仅开启一组发射通 道时可承载用户数和吞吐量与调整后的用户数门限值和吞吐量门限值 相匹配。
可选地， 为了更精确的计算出 "空闲时段" ， 防止因偶然因素带 来的误差， 还可以进一步计算两周前、 三周前的星期一的业务量， 并取 三者的平均值。
步骤 102、 当基站系统在本周期工作于所述第一子时间段时， 开启 第一组发射通道， 并关闭除所述第一组发射通道以外的其他组发射通 道。
在本周的星期一， 当基站系统在本周期工作于第一子时间段， 即 工作于凌晨 2:00〜 6:00时， 开启第一组发射通道 4 , 并关闭除第一组发 射通道 4以外的其他组发射通道， 既满足了用户的需求， 又关闭了闲置 的发射通道， 节约了能耗。
可选地， 为了避免因高频率使用同一组发射通道而带来的器件损 耗， 延长基站系统的寿命， 本实施例可以交替使用发射通道组， 也就是， 当基站系统工作于第二子时间段时， 即星期一的 "空闲时段" 上午 9:00 〜 1 1 :00时， 开启第二组发射通道 5 , 并关闭除第二组发射通道 5以外的 其他发射通道。
假设星期二和星期三的 "空闲时段" 也是凌晨 2:00 〜 6:00和上午 9:00 〜 1 1 :00 , 为实现发射通道组的循环利用， 当基站系统工作于星期二 的凌晨 2:00 〜 6:00时， 可使用第三组发射通道 6 , 并关闭除第三组发射 通道 6以外的其他发射通道；当基站系统工作星期二的上午 9:00 〜 1 1 :00 时， 可使用第四组发射通道 7 , 并关闭除第四组发射通道 7以外的其他 发射通； 当基站系统工作于星期三的 "空闲时段" 凌晨 1 :00 〜 6:00时， 可使用第一组发射通道 4 , 依次类推。
可选地， 当基站系统工作在 "空闲时段" 以外的其它时间段时， 可开启所有的发射通道， 以保证基站系统的正常工作。
进一步的， 由于接收通道 2在工作过程中不消耗功率， 因此， 本实 施例中基站系统的接收通道 2均处于开启状态，以最大化的满足用户需 求。
进一步的， 本实施例的方法所适用的基站系统为码分多址 （Code Division Multiple Access, 简称 CDMA)网络的基站系统或宽带码分多址 ( Wideband Code Division Multiple Access, 简称 WCDMA )网络的基站 系统或通用移动通信 (Universal Mobile Telecommunications System,简称 UMTS) 网 络 的 基站 系 统 或 全球微波互 联接入（Worldwide Interoperability for Microwave Access ,简称 WiMAX) 网络的基站系统或 长期演进 (Long Term Evolution,简称 LTE) 网络的基站系统或时分同步 码分多址 ( Time Division- Synchronous Code Division Multiple Access , 简称 TD- S CDMA ) 网络的基站系统。
本实施例的降低基站系统能耗的方法， 通过将基站系统的发射通 道平均分为若干组发射通道； 然后计算基站系统仅开启一组发射通道能 承载的最大用户数量所对应的用户数门限值和 /或最大吞吐量对应的吞 吐量门限值；当实际用户数量小于所述用户数门限值和 /或吞吐量小于所 述吞吐量门限值的 "空闲时段" 时仅开启一组发射通道， 在保证基站系
统正常工作的情况下， 节约了基站系统的能耗， 此外， 本实施例的方法 通过在 "空闲时段" 交替循环使用发射通道组， 减小了基站系统元器件 的损耗， 延长了基站系统的寿命。
实施例二
本实施例提供一种降低基站系统能耗的方法， 如图 2和图 4所示， 该方法包括：
步骤 201、将基站系统的发射通道平均分为至少包括第一组发射通 道和第二组发射通道的若干组发射通道。
作为本发明的一种实施方式， 用户数门限值和 /或吞吐量门限值可 通过预设的方式得到。 在对用户数门限值和 /或吞吐量门限值进行预设 时， 可根据各个地区业务量情况等的不同进行合理选取， 举例来说， 某 地区在一天 24 时内的平均业务量较大， 即基站系统收发的数据较多， 因此， 可将用户数门限值和 /或吞吐量门限值适当增大， 以保证在下面的 步骤中计算出合理的 "空闲时段" 。
优选的， 为了更准确的得到 "空闲时段" ， 本实施例将 "用户数 量和吞吐量均小于用户数门限值和吞吐量门限值的时间段" 作为 "空闲 时段" 。
在预设好用户数门限值和吞吐量门限值后， 可先初步计算每个发 射通道可承载的最大用户数量和最大吞吐量， 然后再进行分组， 分组的 准则是：
单个发射通道可承载的最大用户数量 X每组发射通道的个数≥预设 的用户数门限值；
单个发射通道可承载的最大吞吐量 X每组发射通道的个数≥预设的 吞吐量门限值。
作为本发明的其中一种实施方式， 本实施例将基站系统的所有发 射通道 1平均分为四组， 如图 4所示， 四组发射通道分别为： 第一组发
射通道 4、 第二组发射通道 5、 第三组发射通道 6、 第四组发射通道 7 , 每组发射通道包括至少一个发射通道 1。
考虑到基站系统仅开启一组发射通道可承载的最大用户数量和最 大吞吐量会因为一些不确定的因素， 包括： 天气变化、 基站系统元器件 老化等而发生改变。 因此， 还需要对任意一组发射通道， 如第一组发射 通道 4的性能进行测试， 判断基站系统仅开启该组发射通道时能够承载 的最大用户数量和最大吞吐量是否大于或等于预设的用户数门限值和 吞吐量门限值相匹配， 如果判断结果为否话， 可以根据测试结果对当前 发射通道的分组情况作适当的调整， 以使基站系统仅开启一组发射通道 时可承载的最大用户数量和最大吞吐量分别大于或等于预设的用户数 门限值和吞吐量门限值。
步骤 202、 获取上一周期内实际用户数量小于用户数门限值和 /或 吞吐量小于吞吐量门限值的时间段， 所述时间段至少包括第一子时间 段， 所述用户数门限值小于或等于所述基站系统开启一组发射通道时可 承载的最大用户数量， 所述吞吐量门限值小于或等于所述基站系统开启 一组发射通道时可承载的最大吞吐量。
一周的七天中， 由于各种因素的影响， 每天的业务量都是不同的， 且存在明显的差距。 研究发现， 每周的同一天内， 如两周前的星期一和 一周前的星期一内， 业务量是基本稳定的， 差距很小。 因此， 作为其中 一种实施方式， 本实施例选取一周七天作为一个周期， 即选取上周的同 一天作为本周相应的这一天的参考， 并计算上周七天内实际用户数量和 吞吐量均小于用户数门限值和吞吐量门限值的时间段。
举例来说，经计算，上星期一的凌晨 2:00〜 6:00和上午 9:00〜 1 1 :00 内， 用户数量和吞吐量均小于用户数门限值和吞吐量门限值， 因此， 凌 晨 2:00〜 6:00和上午 9:00〜 1 1 :00为上星期一的 "空闲时段" ， 可以将 2:00〜 6:00称为第一子时间段， 将 9:00〜 1 1 :00成为第二子时间段。
可选地， 为了更精确的计算出 "空闲时段" ， 防止因偶然因素带 来的误差， 还可以进一步计算两周前、 三周前的星期一的业务量， 并取 三者的平均值。
步骤 203、 当基站系统在本周期工作于所述第一子时间段时， 开启 第一组发射通道， 并关闭除所述第一组发射通道以外的其他组发射通 道。
在本周的星期一， 当基站系统在本周期工作于第一子时间段， 即 工作于凌晨 2:00〜 6:00时， 开启第一组发射通道 4 , 并关闭除第一组发 射通道 4以外的其他发射通道， 既满足了用户的需求， 又关闭了闲置的 发射通道， 节约了能耗。
可选地， 为了避免因高频率使用同一组发射通道而带来的器件损 耗， 延长基站系统的寿命， 本实施例可以交替使用发射通道组， 也就是， 当基站系统工作于第二子时间段时， 即星期一的 "空闲时段" 上午 9:00 〜 1 1 :00时， 开启第二组发射通道 5 , 并关闭除第二组发射通道 5以外的 其他发射通道。
假设星期二和星期三的 "空闲时段" 也是凌晨 2:00〜 6:00和上午 9:00〜 1 1 :00 , 为实现发射通道组的循环利用， 当基站系统工作于星期二 的凌晨 2:00〜 6:00时， 可使用第三组发射通道 6 , 并关闭除第三组发射 通道 6 以外的其他发射通道； 当基站系统工作于星期二的上午 9:00 〜 1 1 :00时， 可使用第四组发射通道 7 , 并关闭除第四组发射通道 7以外的 其他发射通； 当基站系统工作于星期三的 "空闲时段" 凌晨 1 :00〜 6:00 时， 可使用第一组发射通道 4 , 依次类推。
可选地， 当基站系统工作在 "空闲时段" 以外的其它时间段时， 可开启所有的发射通道， 以保证基站系统的正常工作。
进一步的， 由于接收通道 2在工作过程中不消耗功率， 因此， 本实 施例中基站系统的接收通道 2均处于开启状态，以最大化的满足用户需
求。
进一步的， 本实施例的方法所适用的基站系统为 CDMA网络的基 站系统或 WCDMA网络的基站系统或 UMTS网络的基站系统或 WiMAX 网络的基站系统或 LTE 网络的基站系统或 TD-SCDMA 网络的基站系 统。
本实施例的降低基站系统能耗的方法， 通过预设用户数门限值和 / 或吞吐量门限值，并在实际用户数量小于所述用户数门限值和 /或吞吐量 小于所述吞吐量门限值的 "空闲时段" 时仅开启一组发射通道， 实现了 在保证基站系统正常工作的情况下， 节约了基站系统的能耗， 此外， 本 实施例的方法通过在 "空闲时段" 交替循环使用发射通道组， 减小了基 站系统元器件的损耗， 延长了基站系统的寿命。
实施例三
本实施例提供一种降低基站系统能耗的方法， 如图 3和图 4所示， 该方法包括：
步骤 301、 当基站系统在本周期工作于预设的第一子时间段时， 开 启第一组发射通道， 并关闭除所述第一组发射通道以外的其他组发射通 道； 其中， 当所述基站系统处于上一周期所述第一子时间段时， 基站系 统承载的实际用户数量小于所述基站系统开启一组发射通道能承载的 最大用户数量和 /或吞吐量小于所述最大吞吐量。
在预设时间段时， 可根据各个地区业务量情况等的不同进行合理 选取， 举例来说， 经长期观察， 某地区在星期一的凌晨 2:00〜 6:00和上 午 9:00〜 1 1 :00内， 业务量 4艮小， 因此， 凌晨 2:00〜 6:00和上午 9:00〜 1 1 :00设为星期一的 "空闲时段" ， 可以将 2:00〜 6:00称为第一子时间 段， 将 9:00〜 11 :00成为第二子时间段。
本实施例中的周期是指人为设定的时间段， 例如， 周期可以为一 天或者一周或者一个月。 作为其中一种优选实施方式， 本实施例选取一
周七天作为一个周期， 即选取上周的同一天作为本周相应的这一天的参 考， 并计算上星期一凌晨 2:00 〜 6:00和上午 9:00 〜 1 1 :00内的实际用户 数量和 /或吞吐量。
在进行分组时， 可只参考上一周期相应时间段内的实际用户数量 或者上一周期相应时间段内的实际用户数量， 也可同时参考这两个数 值。
优选的， 为了更准确的进行分组， 本实施例同时参考上一周期相 应时间段内的实际用户数量和上一周期相应时间段内的实际用户数量， 具体的方法是： 先初步计算每个发射通道可承载的最大用户数量和最大 吞吐量， 然后再对发射通道进行分组， 分组的准则是：
单个发射通道可承载的最大用户数量 X每组发射通道的个数≥上一 周期相应时间段内的实际用户数量；
单个发射通道可承载的最大吞吐量 X每组发射通道的个数≥上一周 期相应时间段内的实际吞吐量。
可见， 分组后的基站系统仅开启一组发射通道时可承载上一周期 所述时间段内的实际用户数量和吞吐量。
作为本发明的其中一种实施方式， 本实施例将基站系统的所有发 射通道 1平均分为四组， 如图 4所示， 四组发射通道分别为： 第一组发 射通道 4、 第二组发射通道 5、 第三组发射通道 6、 第四组发射通道 7 , 每组发射通道包括至少一个发射通道 1。
考虑到基站系统仅开启一组发射通道可承载的最大用户数量和最 大吞吐量会因为一些不确定的因素， 包括： 天气变化、 基站系统元器件 老化等而发生改变。 因此， 在计算出上一周期所述时间段内的实际用户 数量和吞吐量后， 还需要对当前任意一组发射通道组， 如第一组发射通 道 4的性能进行测试， 判断基站系统仅开启第一组发射通道 4时能够承 载的最大用户数量和最大吞吐量是否分别大于或等于上一周期所述时
间段内的实际用户数量和吞吐量相匹配， 如果判断结果为否话， 可以根 据测试结果对当前发射通道的分组情况作适当的调整， 以使基站系统仅 开启一组发射通道就可以承载上一周期所述时间段内的实际用户数量 和吞吐量。
在本周的星期一， 当基站系统在本周期工作于第一子时间段， 即 工作于凌晨 2:00 〜 6:00时， 开启第一组发射通道 4 , 并关闭除第一组发 射通道 4以外的其他发射通道， 既满足了用户的需求， 又关闭了闲置的 发射通道， 节约了能耗。
步骤 302、预设时间段， 所述时间段至少包括第一子时间段和第二 子时间段， 当基站系统在本周期工作于所述第二子时间段时， 开启第二 组发射通道， 并关闭除所述第二组发射通道以外的其他组发射通道。
为了避免因高频率使用同一组发射通道而带来的器件损耗， 延长 基站系统的寿命， 本实施例交替轮流使用发射通道组， 也就是， 当基站 工作于预设的第二子时间段时， 即星期一的上午 9:00 〜 1 1 :00时， 开启 第二组发射通道 5 , 并关闭除第二组发射通道 5以外的其他发射通道。
假设星期二和星期三的 "空闲时段" 也是凌晨 2:00 〜 6:00和上午 9:00 〜 1 1 :00 , 为实现发射通道组的循环利用， 当基站系统工作于本周期 星期二的凌晨 2:00 〜 6:00时， 可使用第三组发射通道 6 , 并关闭除第三 组发射通道 6以外的其他发射通道； 当基站系统工作于本周期星期二的 上午 9:00 〜 1 1 :00时， 可使用第四组发射通道 7 , 并关闭除第四组发射 通道 7以外的其他发射通； 当基站系统工作于本周期星期三的凌晨 1 :00 〜 6:00时， 可使用第一组发射通道 4 , 依次类推。
可选地， 当基站系统工作在所述 "空闲时段" 以外的其它时间段 时， 可开启所有的发射通道， 以保证基站系统的正常工作。
本实施例的降低基站系统能耗的方法， 通过预设时间段， 然后在 保证每组发射通道能够承载上一周期上述时间段的实际用户数量和 /或
吞吐量的前提下将基站系统的发射通道平均分为若干组发射通道， 且在 基站系统工作于上述时间段时仅开启一组发射通道， 既保证基站系统正 常工作的情况下， 又节约了基站系统的能耗， 此外， 本实施例的方法通 过在上述时间段交替循环使用发射通道组， 减小了基站系统元器件的损 耗， 延长了基站系统的寿命。
