分别作为两个系统的主集和分集的上行信号。
如图 1 所示， 背景技术实现异系统同频段共天馈的示意图中， 假设两个系 统分别为全球移动通信系统（ Global System for Mobile communication: GSM ) 和通用移动通信系统 ( Universal Mobile Telecommunications System: UMTS )并 且两个系统只有主集或分集存在下行信号， 则将两个系统的下行信号分别通过 同频段天馈共用单元（ Same band Antenna Sharing Unit: SASU ), 从单个双极性 天线或两根单极性天线的两个天线单元发送。
目前的异系统共天馈方案中， 要求基站只能在主集或分集的一个天线单元 中有下行信号。 如果系统必须通过两个天线单元输出下行信号， 则需要将主集 和分集端口的两路下行信号合成一路， 才能利用异系统同频段共天馈方案。
现有技术中釆用 3dB桥合路器， 将主集和分集端口的两路下行信号合成一 路。
但是这种 3dB桥合路器对于下行信号的损耗大， 一般为 3.4dB左右， 会导 致基站损失大量的覆盖面积， 在对下行信号功率要求高的场合不适用， 并且这 种 3dB桥合路器不能在分集上接收信号， 从而降低了上行信号的接收效率， 而 且必须配置在基站中， 如果想要使现有基站满足异系统同频段共天馈的方案， 就必须对基站进行重新配置。 综上所述， 目前为了满足异系统同频段共天馈的方案， 使得基站损失大量 的覆盖面积， 而且降低了上行信号的接收效率， 对于现有基站必须重新配置。 发明内容

针对目前现有技术中存在为了满足异系统同频段共天馈的方案， 损失基站 较大覆盖面积的问题， 本发明实施例中根据设置的第一通带范围， 对接收到的 来自基站分集天线接口的信号进行滤波， 根据设置的第二通带范围， 对接收到 的来自基站主集天线接口的信号进行滤波， 将滤波后的所述基站分集天线接口 的信号和所述基站主集天线接口的信号进行合并， 将合并后的信号通过主集通 道接口发送， 从而解决了上述问题。
如图 2所示， 本发明实施例中信号合路装置包括： 第一滤波器 10、 第二滤 波器 20和下行信号合并模块 30。
第一滤波器 10 , 用于根据设置的第一通带范围， 对接收到的来自基站分集 天线接口的信号进行滤波， 分离出分集天线的下行信号。 第二滤波器 20 , 用于根据设置的第二通带范围， 对接收到的来自基站主集 天线接口的信号进行滤波， 分离出主集天线的下行信号。
下行信号合并模块 30 , 用于将第一滤波器 10和第二滤波器 20滤波后的信 号进行合并， 将合并后的信号通过主集通道接口发送。
其中， 下行信号合并模块 30可以是 T型头。
本发明实施例中信号合路装置还可以进一步包括： 第三滤波器 40。
第三滤波器 40 , 用于根据设置的第三通带范围， 对从分集通道接口发送给 基站分集天线接口的信号进行滤波， 分离出分集通道的上行信号。
因为第三滤波器 40能够分离出分集通道的上行信号， 从而增加了信号合路 装置接收上行信号的效率。
本发明实施例中信号合路装置还可以进一步包括： 第四滤波器 50。
第四滤波器 50 , 用于根据设置的第四通带范围， 对从主集通道接口发送给 基站主集天线接口的信号进行滤波， 分离出主集通道的上行信号。
信号合路装置中的滤波器可以是带通滤波器或低通滤波器， 其结构可釆用 腔体， 同轴线， 微带等。
信号合路装置中滤波器的通带范围还可以根据应用环境， 变化覆盖的频段。 如图 3所示， 本发明实施例中信号合路的方法包括下列步骤：
步骤 300、信号合路装置根据设置的第一通带范围， 对接收到的来自基站分 集天线接口的信号进行滤波， 分离出分集天线的下行信号； 根据设置的第二通 带范围， 对接收到的来自基站主集天线接口的信号进行滤波， 分离出主集天线 的下行信号。
步骤 301、信号合路装置将滤波后的基站分集天线接口的信号和基站主集天 线接口的信号进行合并。
步骤 302、 信号合路装置将合并后的信号通过主集通道接口发送。
其中， 步骤 300 中， 信号合路装置还可以根据设置的第三通带范围， 对从 分集通道接口发送给基站分集天线接口的信号进行滤波， 分离出分集通道的上 行信号。 信号合路装置还可以根据设置的第四通带范围， 对从主集通道接口发送给 基站主集天线接口的信号进行滤波， 分离出主集通道的上行信号。
如图 4 所示， 本发明实施例中滤波器设置相邻频段的信号合路装置中， 假 设第一滤波器的第一通带范围和第二滤波器的第二通带范围设置在下行频段， 第三滤波器的第三通带范围和第四滤波器的第四通带范围设置在上行频段， 若 第二通带范围和第四通带范围在相邻频段中， 则第二滤波器和第四滤波器可以 置于同一物理实体中。
将第二滤波器和第四滤波器的功能合并到第五滤波器中， 只需要一个第五 滤波器就可以完成第二滤波器和第四滤波器的功能， 则第五滤波器的通带范围 一部分位于下行频段， 一部分位于上行频段。
第五滤波器， 用于根据设置的第二通带范围， 对接收到的来自基站主集天 线接口的信号进行滤波， 分离出主集天线的下行信号， 根据设置的第四通带范 围， 对从主集通道接口发送给基站主集天线接口的信号进行滤波， 分离出主集 通道的上行信号。
通过这种设置， 可以使信号合路装置中减少一个滤波器， 从而节省了资源。 如图 5所示， 本发明实施例中滤波器频段分配的示意图中， 将第一滤波器， 第三滤波器和第五滤波器的通带范围按照图 4 中设置的频段进行分配。 假设异 系统同频段共天馈中， 两个系统分别为 GSM和 UMTS, 第一滤波器的通带范围 处于下行频段， 第三滤波器的通带范围处于上行频段， 第五滤波器的通带范围 一部分位于上行频段， 一部分位于下行频段。
在进行滤波器配置时， 为了便于实现， 将两个滤波器之间都保留一定间隔 的保护带宽， 而为了不浪费这部分带宽， 从而将 GSM信号分配到频段的两端， 将保护带宽分配给 UMTS信号。
如图 6 所示， 本发明实施例中通过信号合路装置后的信号频谱示意图中， 下行信号都合并到了主集通道接口， 分集通道接口只有上行信号通过， 这样就 满足了异系统同频段共天馈的要求。
如图 7 所示， 本发明实施例中釆用信号合路装置的异系统同频段共天馈的 配置原理图中， 两个基站分别是 GSM基站和 UMTS基站。
GSM基站通过主集天线接口和分集天线接口发送信号。
信号合路装置根据设置的第一通带范围，对接收到的来自 GSM基站分集天 线接口的信号进行滤波， 根据设置的第二通带范围， 对接收到的来自 GSM基站 主集天线接口的信号进行滤波， 将滤波后的 GSM基站分集天线接口的信号和 GSM基站主集天线接口的信号进行合并， 将合并后的信号通过主集通道接口发 送给 SASU。
UMTS将主集天线接口的信号发送给 SASU, SASU将 GSM的下行信号分 布于频带的两端， 将 UMTS的下行信号分布于频带的中间， 并发送。
其中， 信号合路装置还可以根据设置的第三通带范围， 对从分集通道接口 发送给 GSM基站分集天线接口的信号进行滤波； 根据设置的第四通带范围， 对 从主集通道接口发送给 GSM基站主集天线接口的信号进行滤波。
如果 UMTS 的主集天线接口和分集天线接口同时有下行信号， 则可以在 UMTS的天线处增加一个信号合路装置， 信号合路装置将 UMTS的主集天线接 口和分集天线接口的下行信号合并成一路发送给 SASIL
这种配置方式只需将信号合路装置直接安装到基站的天线口就可以对信号 进行合路， 不用对基站进行重新配置。
从上述实施例中可以看出： 本发明实施例中根据设置的第一通带范围， 对 接收到的来自基站分集天线接口的信号进行滤波， 根据设置的第二通带范围， 对接收到的来自基站主集天线接口的信号进行滤波， 将滤波后的所述基站分集 天线接口的信号和所述基站主集天线接口的信号进行合并， 将合并后的信号通 过主集通道接口发送， 因此可以减小对下行信号的损耗， 从而减小了基站损失 的覆盖面积， 并且增加了信号合路装置接收上行信号的效率， 只需将信号合路 装置直接安装到基站的天线口就可以对信号进行合路， 不用对基站进行重新配 置。 明的精神和范围。 这样， 倘若本发明的这些修改和变型属于本发明权利要求及 其等同技术的范围之内， 则本发明也意图包含这些改动和变型在内。
