Definitions

  • buildings are more and more, higher or more dense, or materials used in buildings, which may cause the signals of wireless communication to be blocked and attenuated during transmission, even shielding. Making communication difficult.
  • At the bottom of some buildings, such as underground parking lots, underground shopping malls, subways or tunnels, etc. are usually blind spots and the signal is weak.

Description

分布式基站的节能系统、 设备和方法 技术领域
本发明实施例涉及通信技术领域, 并且更具体地, 涉及分布式基站的节 能系统、 设备和方法。 背景技术
在现代城市化建设中, 建筑物越来越多、 越来越高或者越来越密集, 或 者建筑物采用的材料,导致无线通信的信号在其间传输时可能会受到阻挡而 衰减, 甚至屏蔽,使得通信难于进行。在一些建筑物的底层, 如地下停车场、 地下商场、 地铁或隧道等通常都是盲区, 信号较弱。 另外, 在大中城市的中 心区部署基站较为密集, 因此信号较杂乱, 不稳定, 特别是在一些没有完全 封闭的高层建筑, 进入室内的信号包括近处基站的信号, 以及远处基站通过 直射、 折射、 反射和绕射等方式进入的信号。 这样, 导致干扰严重。 因此, 在这样的环境下, UE ( User Equipment, 用户设备) 小区重选或切换频繁, 导致话音质量差, 掉话现象严重。 而在城市边缘地区, 部署的基站密度小, 在距离基站较远的建筑材料对电磁波仍有损耗,使得通信业受到很大影响和 限制。 在通信网络中通常部署分布式基站系统来解决上述问题。
分布式基站系统, 例如可以是包括 BBU ( Base Band Unit, 基带处理单 元 )、 RRU ( Radio Remote Unit, 射频拉远单元 )、 以及 RRU与 BBU之间为 数字基带信号提供路由的 RHUB ( RRU HUB , 射频拉远单元集线器)所组 成的系统。其中每个 BBU可以支持一个或多个 RHUB,与若干个 RRU连接。 由于通信设备的用电成本在运营商的网络运营支出中所占的比重 4艮高,如何 降低分布式基站系统的电力消耗是亟待解决的问题。
现有技术是以一个 RRU组的粒度来实现节能的。 例如, 在某个 RRU组 支持的小区内的某种无线制式业务量大大降低或者连接的用户设备数量较 少时, 该 RRU组中的所有 RRU内部署的该无线制式仍然需要开启, 这样, 系统还是会造成大量的能耗。 发明内容

本发明的技术方案, 可以应用于各种通信系统, 例如: GSM ( Global System of Mobile communication,全求移动通信系统 ), CDMA( Code Division Multiple Access,码分多址)系统, WCDMA ( Wideband Code Division Multiple Access Wireless , 宽 带码 分多 址 ) , UMTS ( Universal Mobile Telecommunications System,通用移动通信系统 ), GPRS( General Packet Radio Service, 通用分组无线业务), LTE ( Long Term Evolution , 长期演进)等。
UE ( User Equipment , 用户设备), 也可称之为移动终端 ( Mobile Terminal ),移动用户设备等, 可以经无线接入网(例如, RAN, Radio Access Network )与一个或多个核心网进行通信, 用户设备可以是移动终端, 如移 动电话(或称为"蜂窝"电话)和具有移动终端的计算机, 例如, 可以是便携 式、 袖珍式、 手持式、 计算机内置的或者车载的移动装置, 它们与无线接入 网交换语言和 /或数据。
在本发明实施例中, 控制设备可以是 BBU, 还可以是基站控制器, 应 理解, 本发明对此并不限定。 基站控制器, 可以是 GSM ( Global System for Mobile Communications,全球移动通信系统)或 CDMA中的 BSC( Base Station Controller, 基站控制器), 也可以是 WCDMA 中的 RNC ( Radio Network Controller, 无线网络控制器)。
本发明中的制式可以是 LTE 或 WCDMA 或 TD-SCDMA ( Time Division-Synchronous Code Division Multiple Access , 时分-同步码分多址 )或 CDMA2000或 GSM等制式。
在本发明实施例中, 一个部件与另一部件之间的连接, 可包括有线和 / 或无线方式的连接。有线方式可包括但不限于各种介质构成的线缆,如光纤、 导电线缆或半导体线路等; 或者包括其他形式, 如内部总线、 电路、 背板等。 无线方式是能够实现无线通信的连接方式, 包括但不限于射频、 红外线、 蓝 牙等。 两个部件之间可存在内部或外部的接口, 该接口可以是物理接口或逻 辑接口。
图 1是可应用本发明实施例的分布式基站系统的场景示意图。 图 1的场 景图以 LTE系统为例, 为了便于理解, 描绘了 1个 BBU、 1个 RHUB和包 括 8个 RRU ( RRU 0-7 ) 的一组 RRU, 该组 RRU中的所有 RRU属于同一 个小区, 即同一 RRU组的各 RRU下行方向发射同一小区的信号, 上行方向 接收来自同一小区的信号。 其中, BBU负责对来自 BSC的下行数据进行编 码、调制和扩频等处理, 并发送至对应 RHUB; BBU同时负责对来自 RHUB 的数字基带信号进行解调和解码等处理, 将处理后的上行数据信息发送给 BSC。 RHUB 负责将 BBU发送的下行数字基带信号进行光电转换、 串并变 换以及复制处理后, 发送给与自身连接的 RRU; RHUB同时负责将 RRU发 送的上行数字基带信号进行加权求和、 并串变换以及电光转换处理后, 发送 给 BBU; 对于非自身所属的数字基带信号不做处理, 直接转发。 RRU负责 将 RHUB发送的数字基带信号进行串并变换、脉沖成型、数模转换、 功率放 大等处理, 将下行数据经天线发射给 UE; RRU同时负责将来自天线的上行 数据进行射频放大、 模数转换、 匹配滤波以及并串变化等处理后, 发送给 RHUB„
应理解本发明实施例对此并不限定, 一组 RRU中可以包括两个或两个 以上的 RRU。还应注意的是, 与同一组的 RRU连接的 RHUB数目可以是一 个或多个, 与同一个 RHUB连接的 RRU可以分别属于不同的 RRU组。 示 意性地如图 2所示, 例如与 RHUB1连接的 RRU 1至 RRU nl属于第一组的 RRU,或者与 RHUB连接的 RRU nl+1和与 RHUB连接的 RRU nl+2至 RRU nl+n2属于第二组的 RRU。 可选地, 这多个 RHUB还可以进一步地通过一 个 RHUB连接到 BBU。
在现有技术中, 是以一个 RRU组的粒度来实现节能的。 例如, 在某个 RRU组, 如图 2的场景图中的第一组 RRU, 支持的小区内的某种无线制式 业务量大大降低或者连接的用户设备数量较少时,或者在该小区内有业务承 载时, 该 RRU组中的所有 RRU内部署的该无线制式仍然需要开启, 也就是 说, 该小区无法进行关闭实现节能。 这样, 系统会造成大量的能耗。
为解决上述问题, 在本发明中, 以更细的粒度, RRU的粒度实现节能, 通过同一 RRU组中部分 RRU的开启实现该小区的业务承载来减少能耗,避 免电力资源的浪费, 还能够提高节能系统的灵活性。 图 3是本发明一个实施例的分布式基站的节能系统的示意性框图。该节 能系统 300包括 1个控制设备 304,至少一个 RHUB和支持同一小区的一组 RRU,至少一个 RHUB,如 L个, L为正整数,分别是 RHUB- 1 , RHUB-2 , ··· ··· ,
RHUB- 该组 RRU包括至少两个 RRU, 如 N个, N为大于或等于 2的整 数, L个 RHUB中的第 i个 RHUB分别与 N个 RRU中的 Ni个 RRU相连接, i为正整数且取值从 1到 L, 为正整数且 N; = N , 如图 3的示意图中示出 的, 与 RHUB-1连接 个1 1 1;, 分别是 RRU 301-1 , RRU 301-2, ··· ··· ,
RRU 301-N! ; 与 RHUB-2 连接 N2个 RRU , 分别是 RRU 302-1 , RRU 302-3, ……, RRU 302-N2;与 RHUB-L连接 N2个 RRU,分别是 RRU 303-1 , RRU 303-2, ··· ··· , RRU 303-NL。 N个 RRU中每个 RRU支持至少一种制式, 至少一种制式包括第一制式, 如 LTE制式或 WCDMA制式等。 应理解, 与 一个 RHUB连接的 RRU数目可以是 1个或多个, 本发明实施例对此并不限 定。
控制设备 304用于根据 RRU的负载信息通过 L个 RHUB控制 N个 RRU 的节能状态, 使得该 N个 RRU中的 Ml个 RRU中的每个 RRU的第一制式 处于关闭状态, M2个 RRU中的每个 RRU的第一制式处于开启状态, 其中 Ml和 M2均为正整数且 M1+M2=N。 换句话说,控制设备 304用于根据 RRU的负载信息通过至少一个 RHUB 控制一组 RRU的节能状态, 使得该组 RRU中的一部分 RRU的第一制式处 于开启状态且另一部分 RRU的第一制式处于关闭状态。
可选地, 第 i个 RHUB用于根据 Ni个 RRU中开启的 &个 RRU设置该 第 i个 RHUB的第一制式的射频合路方式,即 RHUB在上行方向将 Si个 RRU 的上行基带数据进行合并, 在下行方向将基带数据进行复制分送给该 &个
RRU。 Si为非负整数且 S; = M2 , M2个 RRU包括 Si个 RRU。 即 RHUB根
'■=1
据与该 RHUB连接且属于该 RRU组的第一制式开启的 RRU设置该 RHUB 的第一制式的射频合路方式, 开启的 RRU可以是 1个或多个 RRU, 当然也 可以是 0,表示该 RHUB下属于该 RRU组的所有 RRU的第一制式均处于关 闭状态。 需要说明的是, 控制设备 304可以用于控制 N个 RRU在第一制式的节 能状态,具体地,可以从第一制式均开启的 N个 RRU到上述 Ml个 RRU的 第一制式处于关闭状态和 M2个 RRU的第一制式处于开启状态; 也可以从 第一制式均关闭的 N个 RRU到上述 Ml个 RRU的第一制式处于关闭状态和 M2个 RRU的第一制式处于开启状态;还可以从 N个 RRU中的 M3个 RRU 的第一制式处于开启状态且 M4个 RRU的第一制式处于关闭状态到上述 Ml 个 RRU的第一制式处于关闭状态和 M2个 RRU的第一制式处于开启状态, 其中 M3和 M4均为正整数且 N=M3+M4。 应理解, 本发明实施例对此并不 限定。
基于上述方案, 本发明实施例的节能系统以 RRU的粒度实现节能, 在 属于同一个小区的多个 RRU 中, 能够实现部分 RRU开启第一制式, 部分 RRU 关闭第一制式, 从而提高节能系统的灵活性, 并且无需开启该属于同 一个小区的所有 RRU部署的第一制式就能实现用户设备在该小区的业务, 因此, 能够有效地减少能耗, 避免电力资源的浪费。
作为本发明的另一个实施例,以上节能系统 300还可以进一步扩展其功 能。
示例性的,控制设备 304可以进一步用于从第一制式均处于开启状态的 N个 RRU中确定需要关闭第一制式的 Ml个 RRU, 向 Ml个 RRU所在的 RHUB发送节能关闭信息。 以 Ml个 RRU所在的 RHUB中的任一个(如第 一个 RHUB )为例, 从与第一个 RHUB连接且第一制式均开启的 个 RRU 中确定需要关闭第一制式的 Pi个 RRU,向第一个 RHUB发送关闭节能信息, 关闭节能信息用于指示?1个 RRU中的每个 RRU关闭第一制式, 其中?1为 正整数且 PfNrS Ml个 RRU包括 Pi个 RRU。 第一个 RHUB可以用于分 别向 Pi个 RRU发送节能关闭信息。 Pi个 RRU中的每个 RRU, 用于接收第 一个 RHUB发送的节能关闭信息, 根据节能关闭信息关闭第一制式。
例如, 在图 2的场景中, 假设第二组的所有 RRU的 LTE制式均处于开 启状态,在第二组的 n2个 RRU中, RRU nl+1与 RHUB1连接而其它的( n2-l ) 个 RRU分别与 RHUB2连接, 当前 RHUB1根据开启的 1个 RRU设置 LTE 制式的射频合路方式, RHUB2根据开启的( n2-l )个 RRU设置 LTE制式的 射频合路方式。 BBU检测到在一定时间内 RRU nl+2的 Uu口负载或连接的 用户设备数目或数据吞吐量始终为 0, 确定需要关闭 RRU nl+2, BBU 向 RHUB2发送节能关闭信息, 以指示 RRU nl+2关闭 LTE制式, RHUB2在接 收到 BBU发送的节能关闭信息后, 根据开启的(n2-2 )个 RRU设置 LTE制 式的射频合路方式, 并向 RRU nl+2发送节能关闭信息, RRU nl+2在接收 到节能关闭信息后关闭 LTE制式。
示例性的,控制设备 304可以进一步用于从第一制式均处于关闭状态的 N个 RRU中确定需要开启第一制式的 M2个 RRU, 向 M2个 RRU所在的 RHUB发送节能开启信息。 以 Ml个 RRU所在的 RHUB中的任一个 RHUB (如第一个 RHUB ) 为例, 从与第一个 RHUB连接且第一制式均关闭的 个 RRU中确定需要开启第一制式的 81个 RRU, 向第一个 RHUB发送节能 开启信息, 节能开启信息用于指示 Si个 RRU中的每个 RRU开启第一制式, M2个 RRU包括 Si个 RRU。 第一个 RHUB可以用于分别向 Si个 RRU发送 节能开启信息。 81个1 1 1;中的每个 RRU, 用于接收第一个 RHUB发送的节 能开启信息, ^^据节能关闭信息开启第一制式。
示例性的, 在 N个 RRU中每个 RRU支持至少两种制式的情况下, 至 少两种制式包括第一制式和第二制式,如第一制式为 LTE制式且第二制式为 WCDMA制式; 或者第一制式为 WCDMA制式且第二制式为 LTE制式。 控 制设备 304还可以用于从开启第一制式的 M2个 RRU确定需要进行制式切 换的 W个 RRU,通过 W个 RRU所在的 RHUB将该 W个 RRU的第一制式 下与用户设备进行的业务切换到第二制式并关闭第一制式。
例如,当 RRU的 Uu口的物理资源块的使用率小于或等于第一资源门限 值, 或者 RRU连接的用户设备数量小于或等于第一数量门限值等情况下确 定该 RRU需要从第一制式切换到第二制式。
以 W个 RRU所在的 RHUB中的任意一个 RHUB (如第一个 RHUB ) 为例, 控制设备 304还可以用于从第一个 RHUB开启第一制式的 81个1 1 1; 中确定需要进行制式切换的 Wi个 RRU,向第一个 RHUB发送第一节能切换 信息, 第一节能切换信息用于指示 \¥1个1^11中的每个 RRU将第一制式的 用户设备切换到第二制式并关闭第一制式, 为正整数且 小于或等于 Sl o 第一个 RHUB还可以用于接收控制设备 304发送的第一节能切换信息, 根据开启的 81-\¥1个 RRU设置第一制式的射频合路方式, 并分别将第一节 能切换信息发送给 个 RRU。 个 RRU中的每个 RRU还可以用于将第 一制式的用户设备切换到第二制式并关闭第一制式。

例如,在图 1的场景中,假设该 RRU组 1中的所有 RRU支持两种制式, 分别是 WCDMA制式和 LTE制式, 其中该组的 8个 RRU中的 RRU 0-4的 LTE制式均处于关闭状态, RRU 5-7的 LTE制式均处于开启状态,当前 RHUB 根据开启的 3个 RRU设置 LTE制式的射频合路方式。 BBU检测到在一定时 间内 RRU 7在 LTE制式的负载低于一定的门限值, 如连接的用户设备数目 小于第一数量门限值或者 Uu口的物理资源块的使用率小于 10%,确定 RRU 7需要进行制式切换, BBU向 RHUB发送第一节能切换信息,以指示 RRU 7 将 LTE制式的用户设备切换到 WCDMA制式。 RHUB在接收到 BBU发送的 第一节能切换信息后,根据开启的 2个 RRU设置 LTE制式的射频合路方式; 相应地, 对于 WCDMA制式的射频合路方式与 LTE制式的类似, 即为在该 RHUB下根据开启 WCDMA制式的 RRU设置 WCDMA制式的射频合路。 RHUB将第一节能切换信息发送给 RRU 7, RRU 7在接收到第一节能切换信 息后将 LTE制式的用户设备切换到 WCDMA制式, 并关闭 LTE制式。
因此, 当 RRU具有多种制式时, 而在第一制式下较少的仍在进行无线 业务的用户设备切换到同一个 RRU其它开启的制式上, 这样, 能够关闭该 RRU的第一制式, 实现节能, 避免电力资源浪费。
示例性的, 控制设备 304还可以用于从关闭第一制式的 Ml个 RRU确 定需要开启第一制式的 K个 RRU。 例如, 当 RRU的 Uu口的物理资源块的 使用率大于第二资源门限值, 或者 RRU连接的用户设备数量大于第二数量 门限值等情况下确定该 RRU需要开启第一制式。
以 K个 RRU所在的 RHUB中的任意一个 RHUB (如第一个 RHUB )为 例, 控制设备 304还可以用于从第一个 RHUB关闭第一制式的 (NrS 个 RRU中确定需要开启第一制式的 ^个 RRU, 向第一个 RHUB发送第二节 能切换信息, 第二节能切换信息用于指示 个 RRU中的每个 RRU开启第 一制式, K 为小于或等于 NrSi的正整数。 第一个 RHUB还可以用于接收控 制设备 304发送的第二节能切换信息, 根据开启的 81+ 1个 RRU设置第一 制式射频合路方式, 并分别将第二节能切换信息发送给 个 RRU。 个 RRU中的每个 RRU, 还可以用于开启第一制式。 具体地, K 个 RRU中的每个 RRU满足下列至少一个条件: RRU的 Uu 口的物理资源块的使用率大于第二资源门限值, RRU 连接的用户设备数量 大于第二数量门限值, RRU的数据吞吐量大于第二吞吐量门限值,以及 RRU 的当前使用功率大于第二功率门限值。

又例如, 在图 1的场景中, 假设该 RRU组 1 中的所有 RRU支持 LTE 制式,其中该组的 8个 RRU中的 RRU 0-4的 LTE制式均处于关闭状态, RRU 5-7的 LTE制式均处于开启状态,当前 RHUB根据开启的 3个 RRU设置 LTE 制式的射频合路方式。 BBU检测到在一定时间内 RRU 4在 LTE制式有用户 设备接入, 确定 RRU 4需要开启 LTE制式, BBU向 RHUB发送第二节能切 换信息, 以指示 RRU 4开启 LTE制式。 RHUB在接收到 BBU发送的第二节 能切换信息后, 根据开启的 4个 RRU设置 LTE制式的射频合路方式。 RHUB 将第二节能切换信息发送给 RRU 4, RRU 4在接收到第二节能切换信息后开 启 LTE制式。
再例如, 在图 2的场景中, 在业务闲时的时间段内, 假设第二组的所有 RRU中 RRU nl+1和 RRU nl+2的 LTE制式处于关闭状态,其它 RRU的 LTE 制式处于开启状态, 在第二组的 n2个 RRU中, RRU nl+1与 RHUB1连接 而其它的( n2- 1 )个 RRU分别与 RHUB2连接。在业务闲时的时间段结束后, 可选地, BBU可以分别向 RHUB 1和 RHUB2下发开启命令,以指示 RRU nl+1 和 RRU nl+2开启 LTE制式, 相应地, RHUB1和 RHUB2设置射频合路方 式, 具体地可以参考上述例子, 此处不再赘述。
应理解, 上述例子仅仅是示例性的, 而非要限制本发明的范围。
示例性的, RRU的负载信息可以包括至少下列一种: RRU的 Uu 口的 物理资源块的使用率, RRU连接的用户设备数量, RRU的数据吞吐量, 以 及 RRU的当前使用功率。 应理解, 本发明实施例对此并不限定。
