一种载波控制方法及相应的基站设备
本申请要求于 2011 年 12 月 9 日提交中国专利局、 申请号为 201110409118.6, 发明名称为 "一种载波控制方法及相应的基站设备" 的中国 专利申请优先权， 上述专利的全部内容通过 I用结合在本申请中。 技术领域
本发明涉及移动通信领域，特别是涉及一种载波控制方法及相应的基站设 备。 背景技术
在移动通信系统中，基站占据了通信设备能耗的绝大部分， 降低基站的功 耗对于运营商的节能减排起着至关重要的作用。
基带板是承载载波的物理载体。 通常， 一个基站中有多个基带板， 每个基 带板上承载了一个或者多个载波；基带板上的载波开启后会持续工作， 消耗能 量， 即使没有业务量也是如此。
为了节约能耗， 现有技术所采取的解决高能耗的问题方法为：
当基站检测到无线网络控制器关断负载为零的载波时，基站检查被关断的 载波所在的基带单元上是否存在激活的载波，如果不存在激活的载波， 则将该 基带单元下电， 并且进一步通过调整基带单元上载波的用户数， 关闭基带单元 上调整后用户数为零的载波， 并将调整后不存在激活的载波的基带单元下电， 提高资源利用率， 节约能耗。
现有技术中从基带单元的关断的角度入手， 来提高利用率， 减少资源的消 耗，但是降低能耗的效果并不是非常显著， 所以需要寻找能更显著地降低能耗 的方法。 发明内容
本发明主要解决的技术问题是提供一种载波控制方法，本发明还提供相应 的基站设备， 能够通过当前周期的业务量的变化情况对扇区中的载波进行控 制， 从而节约资料， 提高利用率。
本发明实施例公开了一种载波控制方法， 包括：
获取本基站中各个基带板上的当前周期的业务量信息，所述业务量信息包 括各个扇区的业务量， 其中配置在每个基带板上的载波覆盖一个或者多个扇 区；
根据所述当前周期的业务量信息设置所述各个基带板的关断顺序； 根据保存的本周期之前的各个扇区的业务量信息和所述当前周期的业务 量信息判断每个扇区的业务量的变化情况；
根据所述每个扇区的变化情况和所述每个基带板的关断顺序分别对所述 每个扇区中的载波进行控制。
本发明实施例还公开了一种基站设备， 包括：
获取模块，用于获取所述基站设备中各个基带板上的当前周期的业务量信 息， 所述业务量信息包括各个扇区的业务量， 其中配置在每个基带板上的载波 覆盖一个或者多个扇区；
设置模块，用于根据所述当前周期的业务量信息设置所述各个基带板的关 断顺序；
判断模块，用于根据保存在本地的本周期之前的各个扇区的业务量信息和 所述当前周期的业务量信息判断每个扇区的业务量的变化情况；
控制模块，用于根据所述每个扇区的变化情况和所述每个基带板的关断顺 序分别对所述每个扇区中的载波进行控制。
区别于现有技术的情况，本发明通过获取本基站中一个或者多个基带板上 当前周期的业务量信息，接着根据该当前周期的业务量信息设置基带板的关断 顺序，然后根据保存的本周期之前的业务量信息和获取的当前周期的业务量信 息判断每个扇区的业务量的变化情况，从而能够实时地根据业务量的变化情况 和基带板的关断顺序对扇区中的载波进行控制， 从而能够本着降低能耗的原 贝 |J , 在在业务量没有增大的情况下， 控制更多的设备处于关断状态， 能更好地 减少能耗， 节约资源。 附图说明

参阅图 1 , 本发明中载波控制方法的第一实施例包括：
101、 获取本基站中各个基带板上的当前周期的业务量信息；
基站获取本基站中各个基带板上承载的载波的当前周期的业务量信息，即 本周期的业务量信息，其中，该业务量信息包括的参数有：每个载波的业务量、 基带板上承载的各个载波的用户数、基带板上承载的各个载波的业务量、基带 板上关断的载波数、基带板上开启的载波数和基带板的能耗等等； 其中配置在 每个基带板上的载波覆盖一个或者多个扇区；
进一步的，与基带板有关的参数，可以获取本基站中一部分基带板的参数, 也可以获取本基站中的每个基带板的参数， 此处不做限制；
102、 根据当前周期的业务量信息设置各个基带板的关断顺序；
获取本周期的业务量信息后，再根据该业务量信息设置本基站中各个基带 板的关断顺序， 进一步的，还根据该业务量信息设置本基站中各个基带板的开 启状态级别；
基带板的关断顺序是指在业务量减少的情况下， 基带板被关断的先后顺 序；
基带板的开启状态级别是指该基带板的开启程度，当基带板上所有载波均 打开并且满负载时， 该基带板的开启状态最高， 当基带板处于关断状态时， 该 基带板的开启状态最低；
103、 根据保存在本地的本周期之前的每个扇区的业务量信息和当前周期 的业务量信息判断每个扇区的业务量的变化情况；
每一个载波控制周期开始时获取的业务量信息在该周期结束前会被保存 在本地， 以便下一个周期使用， 具体的，
首先， 获取保存在本地的本周期之前的业务量信息， 然后将该本周期之前 的业务量信息与本周期获取的业务量信息进行比较，判断本周期中每个扇区的 业务量与本周期之前相比的变化情况， 即是否增大；
104、 根据每个扇区的业务量变化情况和每个基带板的关断顺序对每个扇 区中的载波进行控制；
根据每个扇区的业务量变化情况和每个基带板的关断顺序对每个扇区中 的载波进行控制，或者还可以根据每个扇区的业务量变化情况和每个基带板的 开启状态级别对每个扇区中的载波进行控制， 具体的：
如果业务量不变或者减少，则根据每个扇区的业务量变化情况和各个基带 板的关断顺序对每个扇区中的载波进行控制，尽可能关断除覆盖载波之外的负 载为零的载波， 其中覆盖载波为设置为不可关断以保证每个扇区覆盖的载波； 进一步的，如果业务量增大， 则根据每个扇区的业务量变化情况和各个基 带板的开启状态级别对每个扇区中的载波进行控制，尽可能将用户或者业务接 入或者切换到开启状态级别高的载波，从而不开启已经关断的载波或者尽可能 少开启已经关断的载波；
在本实施例中，通过对当前周期的业务量信息进行分析，设置基带板的关 断顺序和开启状态级别，然后根据保存在本地的本周期之前的业务量信息和当 前周期的业务量信息判断每个扇区的业务量的变化情况，再根据业务量的变化 情况、基带板的关断顺序和开启状态级别对扇区中的载波进行控制， 即如果业 务量不变或者减少，则根据业务量变化情况和基带板的关断顺序对每个扇区中 的载波进行控制，尽可能关断除覆盖载波之外的负载为零的载波； 如果业务量 增大，则根据业务量变化情况和基带板的开启状态级别对每个扇区中的载波进
行控制，尽可能将用户或者业务接入或者切换到开启状态级别高的载波，从而 不开启已经关断的载波或者尽可能少开启已经关断的载波；本发明提供的方法 在同等情况下， 减少了载波的开启， 减少了基站单元的能耗， 节约了资源。
请参阅图 2和图 3 , 本发明中载波控制方法的第二实施例包括：
201、 获取载波的当前周期的业务量信息；
基站获取本基站中各个基带板上承载的载波的当前周期的业务量信息，即 本周期的业务量信息， 其中， 业务量信息包括的参数有： 每个载波的业务量、 基带板上承载的各个载波的用户数、基带板上承载的各个载波的业务量、基带 板上关断的载波数、 基带板上开启的载波数和基带板的能耗等等；
进一步的，与基带板有关的参数，可以获取本基站中一部分基带板的参数， 也可以获取本基站中的每个基带板的参数， 此处不做限制；
202、 根据当前周期的业务量信息设置基带板的关断顺序；
获取到本基站中各个扇区中载波的当前周期的业务量信息后，根据该业务 量信息设置各个基带板的关断顺序，例如可以通过设置一个队列对各个基带板 的关断进行排序，或者还可以通过给基带板贴优先级标签来实现对每个基带板 的关断顺序的排序， 此处不做限制；
根据当前周期的业务量信息的参数的一项或者多项设置各个基带板的关 断顺序， 以通过给基带板贴优先级标签来具体描述：
根据各个基带板上承载的各个载波的用户数或者基带板上承载的各个载 波的业务量的大小排序， 然后根据该大小排序设置各个基带板的关断顺序； 基带板上承载的各个载波的用户数越多或者基带板上承载的各个载波的 业务量越大，基带板的关断优先级越低，基带板上承载的各个载波的用户数越 少或者基带板上承载的各个载波的业务量越小， 基带板的关断优先级越高； 或者，
根据每个基带板上承载的各个载波的用户数和各个载波所在的基带板上 关断的载波数， 利用预先设定的计算方法获取计算结果，对该计算结果进行大 小排序， 然后根据该大小排序设置各个基带板的关断顺序；
例如，根据基带板上承载的各个载波的用户数总和以及基带板上开启的载 波数来决定基带板的关断优先级，假设基带板上的用户数为 M, 开启的载波数
为 N,令丫 = ^1 + 1(^, 根据 Y值的大小来设置基带板的关断优先级， Υ值越 大， 关断优先级越低， Υ值越小， 关断优先级越高； 其中， 计算方法是可以根 据具体情况和需要达到的预期预先设置的， 此处不做限制；
又如，根据基带板上关断的载波数来设置每个基带板的关断顺序，基带板 上关断的载波数越多， 该基带板的关断顺序越靠前；
此处只是对设置基带板的关断顺序做具体的举例说明，基带板的关断顺序 的设置方法不限于上述几种，例如还可以根据各个基带板上载波的用户数和各 个基带板的能耗对基带板的关断顺序进行设置等等； 此处不做限制；
203、 根据业务量信息设置基带板的开启状态级别；
基带板的开启状态级别是指该基带板的开启程度，当基带板上所有载波均 打开并且满负载时， 该基带板的开启状态最高， 当基带板处于关断状态时， 该 基带板的开启状态最低；
根据当前周期的业务量信息中的一项或者多项参数对每个基带板的开启 状态级别进行设置， 具体的：
根据基带板上承载的各个载波的用户数或者基带板上承载的各个载波的 业务量来设置各个基带板的开启状态级别：
根据基带板上承载的各个载波的用户数或者基带板上承载的各个载波的 业务量的大小排序， 然后根据该大小排序设置每个基带板的开启状态级别； 基带板所承载的用户数越多， 开启状态级别越高，基带板所承载的用户数 越少， 开启状态级别越低， 关断态基带板的开启状态级别最低；
基带板所承载各个载波的业务量越大， 开启状态级别越高，基带板所承载 各个载波的业务量越小， 开启状态级别越低；
或者，
根据基带板的能耗来设置各个基带板的开启状态级别： 能耗越高的基带 板， 承载量越大， 开启状态级别越高， 能耗越低的基带板， 承载量越小， 开启 状态级别越低；
此处只是对设置基带板的开启状态级别做具体的举例说明，基带板的开启 状态级别的设置方法不限于上述几种，例如还可以根据各个基带板上开启的载 波数和基带板的能耗对基带板的开启状态级别进行设置等等； 此处不做限制；
在设置了每个基带板的开启状态级别后， 开启状态级别越高的基带板， 该 基带板的关断顺序越靠后， 同理， 该基带板中承载的载波的关断顺序越靠后； 并且，在对载波进行整合或者业务量增大的时候，将用户优先切换或者接入到 开启状态级别高的基带板上；
204、 根据保存在本地的本周期之前的业务量信息和当前周期的业务量信 息判断每个扇区的业务量是否增大；
每一个载波控制周期开始时获取的业务量信息在该周期结束前会被保存 在本地， 以便下一个周期使用， 具体的：
首先， 获取保存在本地的本周期之前的业务量信息， 然后将该本周期之前 的业务量信息与本周期获取的业务量信息进行比较，判断本周期中每个扇区的 业务量与本周期之前相比，是否增大； 如果本周期中某扇区的业务量与本周期 之前相比增大， 则在该扇区中执行步骤 209, 如果本周期中某扇区的业务量与 本周期之前相比保持相同或者减少， 则在该扇区中执行步骤 205;
205、 根据当前周期的业务量信息和基带板的关断顺序设置扇区中载波的 关断顺序；
如果步骤 204 中判断出本扇区在本周期业务量与本周期之前保持相同的 业务量或者减少，则根据当前周期的业务量信息和各个基带板的关断顺序设置 本扇区中载波的关断顺序， 具体的， 例如当前周期的业务量信息中的某个载波 的用户数越多或者业务量越大， 该载波的关断顺序越靠后，如果要给该载波贴 关断优先级标签的话， 该载波的关断优先级越低； 并且在考虑了载波的用户数 和业务量的基础上，还需要考虑该载波所在的基带板的关断顺序， 该载波所在 的基带板的关断顺序越靠后， 该载波的关断顺序也越靠后， 即该载波的关断优 先级越低；
206、 根据扇区中的载波的关断顺序和当前周期的业务量信息关断除覆盖 载波之外的负载为零的载波；
在每个扇区中都有一个覆盖载波，该覆盖载波为设置为不可关断以保证每 个扇区覆盖的载波， 其中，将每个扇区中载波的关断顺序排在最后的那个载波 设置为本扇区的覆盖载波； 在设置覆盖载波时，尽量将各个扇区的覆盖载波设 置在同一块基带板上；
在设置好每个扇区中载波的关断顺序后，再根据各个扇区中的载波的关断 顺序和当前周期的业务量信息关断除覆盖载波之外的负载为零的载波， 具体 的：
将每个扇区中载波的关断顺序中排在前面的载波上的用户切换至载波的 关断顺序中排在后面的载波上， 然后关断负载为零的载波； 例如， 在某个扇区 中， 有载波 1 , 载波 2和载波 3 , 这 3个载波的关断顺序为： 载波 2>载波 3> 载波 1 , 即最优先关断载波 2, 载波 1是覆盖载波， 当该扇区的业务量下降时， 最优先将载波 2的用户切换至覆盖载波 1 , 然后将载波 2关断； 如果该扇区中 载波 3的业务量也很低，用户数也很少， 并且载波 1的业务量和用户数都未饱 和， 则将载波 3用户切换至覆盖载波 1 , 然后将载波 3关断；
请参阅图 3 , 在业务量不变或者减少的情况下， 根据扇区中的载波的关断 顺序和当前周期的业务量信息依次关断除覆盖载波之外的负载为零的载波的 步骤具体为：
301、 获取关断顺序最靠前的基带板上的载波的用户数；
首先，根据当前周期的业务量信息获取关断顺序最靠前的基带板上的载波 的用户数，也可以获取关断顺序最靠前的基带板上的载波的业务量， 此处不做 限制；
302、 判断该基带板上是否存在负载为零的载波；
获取基带板上的载波的用户数之后，再根据获取的用户数判断该基带板上 是否存在负载为零的载波， 如果存在负载为零的载波， 直接执行步骤 303 , 如 果不存在负载为零的载波， 则跳过步骤 303 , 直接执行步骤 304;
303、 关断所选基带板中负载为零的载波；
如果步骤 302中判断出所选的基带板上存在负载为零的载波，则关断该基 带板中负载为零的载波；
304、 判断所选基带板上是否存在负载不为零的载波；
步骤 302中判断出所选的基带板上不存在负载为零的载波， 或者步骤 303 中关断了所选基带板中负载为零的载波后，再判断所选基带板上是否存在负载 不为零的载波， 如果存在负载不为零的载波， 则执行步骤 305 , 如果不存在负 载不为零的载波， 则执行步骤 307;
305、 判断所选基带板上的载波是否满足调整条件；
如果步骤 304中判断出存在负载不为零的载波，则再判断所选基带板上的 载波是否满足调整条件，即判断所选基带板上的载波是否是不可关断的覆盖载 波，如果是覆盖载波则不满足调整条件； 或者所选基带板上的载波的用户和业 务当前是否不能被切换，如果不能被切换则不满足调整条件； 以上只是对是否 满足调整条件的判断条件的举例， 不能作为对本发明的限制；
如果判断出所选基带板上的载波满足调整条件， 则执行步骤 306, 如果不 满足调整条件， 则执行步骤 307;
306、 将所选基带板中负载不为零的载波上的用户切换至该基带板以外的 载波上；
如果步骤 305中判断出所选基带板上的载波满足调整条件，则将所选基带 板中负载不为零的载波上的用户切换至该基带板以外的载波上； 例如：
基站中有基带板 、基带板 B和基带板 C, 所选的基带板为 A, 首先判断 基带板 A中是否存在负载不为零的载波 a, 如果带板 A中存在负载不为零的 载波 a, 则再判断除基带板 A以外的基带板上是否存在关断的载波， 如果判断 出基带板 B上有关断的载波 b, 则为载波 b供电， 并在载波 b处为载波 a进行 热备份， 然后将载波 a上的用户切换至为其热备份的载波 b上， 再将载波 b配 置在原载波 a处； 再判断基带板 A中是否存在其他负载不为零的载波 a, 依次 循环， 直至基带板 A中不存在负载不为零的载波， 或者除基带板 A之外的其 他基带板上不存在 关断的载波；
307、 关断所选基带板上负载为零的载波；
当将所选基带板中负载不为零的载波上的用户都切换至该基带板以外的 载波上后， 再将所选基带板上负载为零的载波关断；
308、 判断是否检查完需要检查的基带板；
检查完一个基带板后需要检查下一个基带板之前，先判断是否已经检查完 需要检查的基带板， 如果已经检查完所有需要检查的基带板， 则结束流程； 如 果还未检查完所有需要检查的基带板， 则执行步骤 309;
309、 依照基带板的关断顺序， 获取下一个基带板上的载波的用户数； 如果步骤 308中判断出还未检查完需要检查的基带板，则获取取下一个基
带板上的载波的用户数， 然后返回步骤 302;
在业务量未增大时，将扇区中的各个载波中的用户整合到某一个或者几个 载波中，尽可能使关断的载波处于同一块基带板上，从而为关断用户数为零的 基带板创造了条件；
207、 依次判断基站中各个基带板的载波是否都关断， 如果都关断， 执行 步骤 208, 如果还有未关断的载波， 则继续为该基带板供电；
208、 关断基带板；
如果所选的基带板的载波都已经 关断了， 则将该载波都关断的基带板下 电；
209、 根据当前周期的业务量信息和基带板的开启状态级别设置扇区中载 波的开启顺序；
载波的开启顺序是针对关断的载波进行设置的，在扇区业务量增大的情况 下，基站优先开启该扇区中开启顺序排在前面的载波，载波的开启顺序是根据 当前周期的业务量信息中的一个或者多个参数和基带板的开启状态级别设置 的； 例如：
根据基带板的开启状态级别设置： 基带板的开启状态级别越高， 该基带板 上的载波的开启顺序越靠前；基带板的开启状态级别越低， 该基带板上的载波 的开启顺序越靠后；
还可以根据当前周期的业务量信息中的一个或者多个参数设置载波的开 启顺序，例如根据载波所能承载的业务量的大小或者用户数的大小来设置载波 的开启顺序；
还可以将当前周期的业务量信息中的参数和基带板的开启状态级别一并 考虑， 对载波的开启顺序进行设置， 根据不同的情况， 具体的设置有所不同， 但是主要依据的思路是一致的，即尽可能地让更多的载波和基带板处于关断状 态， 减少基带单元的能耗；
210、 根据当前周期的业务量信息和载波的开启顺序设置载波的接入和切 换顺序；
在业务量增大的情况下， 有很多新用户需要接入或者切换到基站的载波， 需要根据当前周期的业务量信息和载波的开启顺序设置载波的接入和切换顺
序；
根据载波的开启顺序来设置，一个载波的开启顺序越靠前， 该载波的接入 和切换顺序也越靠前， 即新的用户越优先接入或者切换到该载波；
还可以根据当前周期的业务量信息来设置， 例如同一基带板上的载波，用 户数越多， 接入和切换的优先级也越高， 即接入和切换顺序越靠前；
还可以将当前周期的业务量信息中的参数和载波的开启顺序一并考虑，对 载波的接入和切换顺序进行设置， 根据不同的情况， 具体的设置有所不同， 但 是主要依据的思路是一致的，即要将新接入或者切换的用户集中到一部分载波 上， 使尽可能多的载波和基带板进入或处于关断状态， 减少基带单元的能耗； 211、 按照载波的开启顺序开启载波；
根据当前周期的业务量信息中的具体业务需求，优先选择开启优先级高的 载波， 即开启顺序靠前的载波；
进一步的， 本实施例还包括步骤， 当执行完本周期流程后， 将本周期之前 获取的业务量信息用本周期获取的业务量信息替换， 以备下一周期使用； 在本实施例中，通过对当前周期的业务量信息进行分析， 当业务量对比本 周期之前没有增大的情况下， 设置基带板、基带板上的载波的关断顺序， 将同 个扇区中的载波的用户尽量接入或者切换到同一个或者少数几个业务量大的 载波上， 并将负载不为零的载波尽量整合到同一个基带板上，从而将其他负载 为零的基带板下电， 减少了能耗， 节约了资源； 并且当业务量对比本周期之前 增大的情况下，将新接入或者切换的用户集中到一部分载波上，按照预先设置 的载波开启顺序开始载波， 使尽可能多的载波和基带板进入或处于关断状态， 减少基带单元的能耗， 节约了资源。
请参阅图 4A至图 6, 通过对一个具体的应用场景的描述进一步对本发明 技术方案进行详细描述， 具体的：
本发明的技术方案主要应用于多基带板多载波的异频同覆盖场景，尤其在 业务闲时段或中低业务量下使用。
关于基带板和载波的映射关系， 大致可以分为三种配置， 下面对三种配 置分别进行具体描述：
配置一： 覆盖同一扇区的不同载波配置在不同的基带板上， 配置在同一基
带板上的不同载波覆盖不同的扇区。 如图 4A所示， 扇区 1中包含载波 Fll、 F12和 F13,扇区 2中包含载波 F21、 F22和 F23,扇区 3中包含载波 F31、 F32 和 F33,基带板 1上负载载波 Fll、 F21和 F31 ,基带板 2上负载载波 F12、 F22 和 F32, 基带板 3上负载载波 F13、 F23和 F33;
基站首先获取本基站中的载波本周期的业务量信息，该业务量信息包括每 个载波的业务量、基带板上承载的各个载波的用户数、基带板上承载的各个载 波的业务量、基带板上关断的载波数、基带板上开启的载波数和基带板的能耗 等参数；
获取到本基站中载波的当前周期的业务量信息后，根据该当前周期的业务 量信息设置基带板的关断优先级和开启状态级别，例如根据基带板各个载波的 用户数的总和来设置关断顺序， 用户数越多的基带板， 关断优先级越低； 假设 本基站中的基带板的关断优先级为： 扇区 2>扇区 1>扇区 3; 开启状态级别为： 扇区 3>扇区 1>扇区 2;
获取保存在本地的本周期之前的业务量信息，将本周期获取的业务量信息 和本周期之前的业务量信息进行比较， 判断本周期的业务量是否增大，假设在 每个扇区中本周期获取的业务量信息和本周期之前的业务量信息进行比较的 结果是本周期的业务量比本周期之前都减少了，则根据本周期的业务量信息和 各个基带板的关断顺序设置每个扇区中载波的关断顺序，假设设置的每个扇区 中载波的关断顺序为：
扇区 1中： F11>F12>F13, 其中 F31为扇区 1的覆盖载波；
扇区 2中： F22>F21>F23 , 其中 F23为扇区 2的覆盖载波；
扇区 3中： F32>F31>F33 , 其中 F33为扇区 3的覆盖载波；
然后对各个扇区中的载波进行整合， 具体的：
例如， F11和 F22负载为零， F12、 F21、 F32以及 F31满足调整条件， 根据图 3中的执行流程将载波 F11和 F22关断， 然后将载波 F12的用户切换 到载波 F13, 将载波 F21的用户切换到载波 F23, 将载波 F32和 F31的用户切 换到载波 F33;
各个扇区中的载波都整合好后， 将负载为零的载波关断， 即将 Fll、 F12、 F22、 F21、 F32以及 F31关断， 然后将负载为零的基带板关断， 即将基带板 1
和基带板 2关断；
调整后的载波覆盖情况如图 4B所示， 基带板 2和基带板 3均已关断， 只 有基带板 1处于工作状态；
在业务量小的情况下，将扇区中的载波进行整合，尽量都将用户切换或者 接入到同一个或者几个基带板中，然后把负载为零的基带板关断，减少了能耗， 节约了资源。
配置二： 覆盖同一扇区的不同载波配置在同一块基带板上， 配置在同一基 带板上的不同载波覆盖同一扇区。如图 5所示，扇区 1中包含载波 F11和载波 F12,扇区 2中包含载波 F21和载波 F22,基带板 1上负载载波 F11和载波 F12, 基带板 2上负载载波 F21和载波 F22;
在该配置中， 即使业务量很低， 也不能关闭基带板， 以免影响覆盖。 为了 实现节能，在基带单元开始启动时，按照配置三的方式重新配置载波在基带板 上的位置，使得同一个基带板上负载有不同扇区的载波， 或者在基带单元的工 作过程中， 按照载波的关断优先级， 进行载波的切换和调整， 使得同一个基带 板上负载有不同扇区的载波；
在本配置中，将基带板上的载波调整为同一个基带板上负载有不同扇区的 载波后，再按照上述配置 1中的载波整合和控制方法对本基站中的载波进行整 合的控制， 以实现基带板的下电。
配置三： 配置在同一基带板上的不同载频可能覆盖不同的扇区，也可能覆 盖同一个扇区。 如图 6所示， 扇区 1中包含载波 Fll、 F12和 F33, 扇区 2中 包含载波 F21、 F22和 F32, 扇区 3中包含载波 F13、 F23和 F31 , 基带板 1上 负载载波 Fll、 F12和 F13, 有 2个载波覆盖扇区 1 , 1个载波覆盖扇区 3; 基 带板 2上负载载波 F21、 F22和 F23, 有 2个载波覆盖扇区 2, 1个载波覆盖扇 区 3; 基带板 3上负载载波 F31、 F32和 F33, 分别覆盖扇区 3、 扇区 2和扇区 1;
在配置三中， 当三个扇区的业务量都很低时， 关闭基带板 1和基带板 2, 保留基带板 3, 每个扇区均有一个载波工作， 既可以保证覆盖， 又能达到节能 的目的； 三个扇区的业务量都比较低时， 关闭基带板 3, 保留基带板 1和基带 板 2。 每个扇区均有两个载波工作； 当扇区 2的业务量很低， 而扇区 1的业务
量 4艮高时， 关闭基带板 2, 使扇区 2上有一个载波， 扇区 3上有二个载波， 扇 区 1上有三个载波。同理， 当扇区 1的业务量 ^艮低时，扇区 2的业务量 ^艮高时， 关闭基带板 1 ; 具体的载波调整和控制过程参考实施例二中或者本应用例中配 置 1中的具体描述， 此处不 #文赞述。
