具体的参照图 5所示， 本发明提供的基站还包括接收 /发射机， 在多 模基站中每一种制式的服务通过相应的接收 /发射机进行信号的接收或发 送， 检测单元通过接收 /发射机提供的信号检测当前状态下小区的平均业 务量， 当然也可以通过其他途径， 例如在接收或发送信号的其他环节进 行检测， 当然这里只是以在接收 /发射机上进行检测为例进行说明； 本发明的基站包括有源天线系统 （ Active Antenna System, AAS ) 收 发天线，其中 AAS收发天线主要由不同频段的无源天线和有源天线组成。 集成多个频段是为了能在系统中支持多种制式和不同国家对频段的要 求。 AAS收发天线的无源天线部分为服务区域提供基本的制式（ 2G或 3G ) 和业务覆盖， 有源天线部分提供演进制式（3G或 4G )的容量覆盖， 并可 以根据服务区域用户业务量的变化情况实时调整业务容量和覆盖区域， 上述的接收 /发射机与 AAS收发天线连接，用于接收和发送携带信息的射 频信号， 其中第一接收 /发射机 35a提供第一制式 UMTS的信号接收或发 送、 第一接收 /发射机 35b提供第二制式 LTE的信号接收或发送； 当然对 应上述两组接收 /发射机， 本实施例中亦釆用两组检测单元， 即通过第一 检测单元 32a检测第一接收 /发射机 35a接收或发送的第一制式 UMTS的 信号， 通过第二检测单元 32b检测第二接收 /发射机 35b接收或发送的第 二制式 LTE的信号； 以下对该实施例中基站的各个组成结构的功能进行 简单描述， 当然这些功能是由上述方法和设备实施例中提供的基站以及 基站各个单元或模块的功能所决定的， 并且是与上述方法和设备实施例 中提供的基站以及基站各个单元或模块的功能相对应的， 具体的：
AAS收发天线 30: 由不同频段的无源天线和有源天线构成， 用于接 收和发送携带信息的射频信号。
天线控制单元 31 : 用于控制 AAS有源天线的开启 /关断， 以及天线 发射参数， 其中发射参数包括： 波束宽度、 方向和功率。
第一接收 /发射机 35a: 用于完成 UMTS收发信号的基带处理、 中射 频处理和功率放大。 第二接收 /发射机 35a: 用于完成 UMTS收发信号的基带处理、 中射 频处理和功率放大。 第一检测单元 32a用于基本覆盖小区业务量检测， 检测 UMTS的业 务负载及对用户接入进行控制。
第二检测单元 32b用于容量覆盖小区业务量检测， 检测 LTE的业务 负载及对用户接入进行控制。
话务控制单元 34 , 用于统计 UMTS和 LTE小区的业务量， 并形成 AAS 覆盖小区的话务地图， 以及根据业务量的变化情况对话务地图进行 更新。
覆盖控制单元 33用于根据小区业务量变化情况或话务地图信息， 判 断 AAS有源天线是否进行工作模式转换 ,选择 AAS有源天线的覆盖范围 , 并向天线控制单元 31发送控制指令。 基站通过接口与网关交换控制信息进而实现与网络的信息交互， 例 如站间同步、 接入请求与响应、 业务量统计上报、 基带信号传输控制和 小区话务分布等信息。 以上仅是本发明提供的一个实施例， 当然其中也可以将第一制式设 为 GSM、 第二制式设为 LTE; 或者， 第一制式设为 GSM、 第二制式设为 UMTS; 或者， 第一制式设为 GSM、 第二制式设为 TD-SCDMA; 或者， 第一制式设为 TD-SCDMA、 第二制式设为 TD-LTE, 此时仅仅需要将对 应的功能单元或模块的功能按照相应的制式进行调整， 具体实施方法不 再赘述。
通过以上的基站和基站控制方法可以根据不同时段区域用户业务量 的变化实时调整业务容量和覆盖区域； 例如， 在低业务量情况下关闭多 余的容量小区、 在中等业务量情况下提供精确的容量小区覆盖和在高业 务情况下提供最大的容量小区覆盖。
图 6 提供了一种基站工作模式的示意图， 表明了在低业务量时基站 的 AAS收发天线对小区的覆盖范围。
当基站服务区域的用户业务量处于较低状态时 （比如夜间至凌晨时 间段） ， 服务区域内的活动用户数和数据吞吐量很少。 这时只需要开启 基本制式和业务覆盖小区（如 Cell A )就能满足服务区域的业务需求， 提 供容量的小区（如 Cell B )可以关闭或休眠，达到节省基站用电量的目的。
图 7 提供了另一种基站工作模式的示意图， 表明了在中等业务量时 基站的 AAS收发天线对小区的覆盖范围。
当基站服务区域的用户业务量处于中等状态时 （比如白天的日常工 作时间段） ， 服务区域内的平均活动用户数和数据吞吐量一般， 局部区 域的业务量比平均值高一些。这时除了开启基本制式和业务覆盖小区（如 Cell A ) , 也需要开启提供容量的小区 （如 Cell Β ) , 以满足用户的业务 需求。 根据各小区用户分布集中程度的差异， 一些容量小区可对服务区 域提供全覆盖 （用户分布均匀， 如 Cell Bl , f2 ) , 即增加基本覆盖小区 的容量， 而其它小区则在识别用户比较集中区域的基础上， 利用有源天 线波束赋形实现精准照射的特性， 对基本覆盖小区内的热点区域提供精 确覆盖 （用户分布较集中， 如 Cell B2, f3、 Cell B3 , β、 Cell Βη, β ) , 满足热点区域的容量增大需求。 因此， 在容量超出基本覆盖小区容量的 情况下， 开启容量小区可实现网络容量跟随业务增长而弹性变化， 并且 按照用户业务分布区域实现精准能量投放， 避免了发射功率的无效散射， 从而达到减少基站功耗的目的。 图 8 提供了又一种基站工作模式的示意图， 表明了在高业务量时基 站的 AAS收发天线对小区的覆盖范围。 当基站服务区域的用户业务量处于高峰状态时 （比如市区主要商业 中心的营业时间段） ， 服务区域内的平均活动用户数和数据吞吐量很高。 这时除了开启基本制式和业务覆盖小区 （如 Cell A )和容量小区 （如 Cell B )夕卜， 为满足某些时段和某个时期内用户业务量快速增大的需求， 容量 小区还需要通过控制有源天线的波束赋型实现小区劈裂 （水平或垂直方 式， 如图将容量小区进行小区劈裂为 Cell B l , f2和 Cell B2 , f2 ) , 进一 步扩大容量小区提供的吞吐量， 为该小区的用户提供满足业务需求的最 大服务容量。
因此， 由上述三种工作状态可知， 基于 AAS的基站能够根据覆盖区 域的业务量变化实时调整天线覆盖波束， 既可实现基站功耗与其服务小 区的业务量需求相吻合， 又避免了基站发射功率的浪费， 达到节省基站 功耗的目的， 从而实现了网络效能的提升。 参照图 9 所示， 本发明实施例还提供一种基站， 用于实现本发明实 施例提供的多模基站控制方法， 具体的， 参照图 9 所示， 包括： 至少一 个处理器 91、 存储器 92、 接收机 93、 发射机 94及数据总线 95 , 数据总 线 95用于实现处理器 91、 存储器 92、 接收机 93及发射机 94之间的连 接及通讯， 存储器 92用于存储处理器 91执行的程序代码及数据；
