Description

有源DAS系统中继端增益控制方法和装置、中继端机 技术领域
本发明涉及移动通信技术领域，特别是涉及一种有源DAS系统中继端增益控制方法和装置、中继端机。
背景技术
随着移动通信的网络建设和客户应用需求的快速发展，移动通信信号的覆盖需求和质量要求日益旺盛，有源DAS(Distributed Antenna System，分布式天线系统)逐渐成为实现高质量、深度覆盖的优选方案。在进行移动通信信号覆盖时，为了满足不同的覆盖场景，不同功率的DAS(混合组网进行覆盖)的方式已经十分普遍。
在进行有源DAS系统的设计开发时，根据设备功率等级不同，上行噪声底抬升以及接收灵敏度和覆盖范围的权衡也不同，有源DAS系统增益及系统内部增益分配(尤其是上行链路)存在较大的差别，导致一种DAS系统的中继端机只能接入一种功率等级的远端机，也就是说，一种中继端机不能兼容不同功率等级的远端机的接入，因此覆盖方案设计就比较复杂，网络建设成本高。
发明内容
针对上述现有技术中存在的技术问题，本发明的目的在于提供一种有源DAS系统中继端增益控制方法和装置、中继端机，可以兼容不同功率等级的远端机，简化覆盖方案设计的复杂度，增加网络建设的灵活度，降低网络建设成本。
本发明的目的通过如下技术方案实现：
一种有源DAS系统中继端增益控制方法，包括如下步骤：
获取接入有源DAS系统的远端机的下行输出功率值，并获取所述有源DAS系统的中继端机的上行最大增益值；
结合所述下行输出功率值、所述上行最大增益值获得所述远端机所在上行 链路需要设置的衰减调节值；
根据所述衰减调节值对所述上行链路中的可调衰减器进行设置。
一种有源DAS系统中继端增益控制装置，包括：
获取模块，用于获取接入有源DAS系统的远端机的下行输出功率值，并获取所述有源DAS系统的中继端机的上行最大增益值；
处理模块，用于结合所述下行输出功率值、所述上行最大增益值获得所述远端机所在上行链路需要设置的衰减调节值；
控制模块，用于根据所述衰减调节值对所述上行链路中的可调衰减器进行设置。
一种中继端机，包括上述的有源DAS系统中继端增益控制装置。
根据上述本发明的方案，其是获取接入有源DAS系统的远端机的下行输出功率值，并获取所述有源DAS系统的中继端机的上行最大增益值，结合所述下行输出功率值、所述上行最大增益值获得所述远端机所在上行链路需要设置的衰减调节值，根据该衰减调节值对所述上行链路中的可调衰减器进行设置，由于是基于远端机的下行输出功率值对相应上行链路中的可调衰减器进行设置，而每个上行链路都可以按照本发明方案对相应上行链路中的可调衰减器进行设置，因此，对于下行输出功率值各不相同的远端机所在上行链路的增益也各不相同，实现了对不同功率等级的远端机的兼容，简化了覆盖方案设计的复杂度，增加了网络建设的灵活度，降低了网络建设成本。

具体实施方式
为使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进行进一步的详细说明。应当理解，此处所描述的具体实施方式仅仅用以解释本发明，并不限定本发明的保护范围。
在下述说明中，首先针对有源DAS系统中继端增益控制方法的实施例进行说明，再对本发明的有源DAS系统中继端增益控制装置的各实施例进行说明，最后对本发明的中继端机的实施例进行说明。
参见图1所示，为本发明的有源DAS系统中继端增益控制方法实施例的流程示意图。如图1所示，本实施例中的有源DAS系统中继端增益控制方法包括如下步骤：
步骤S101：获取接入有源DAS系统的远端机的下行输出功率值，并获取所述有源DAS系统的中继端机的上行最大增益值；
本实施例中的接入有源DAS系统的远端机一般是通过光接口与有源DAS系统的中继端机连接；其中，光接口一般是指光纤接口；
本实施例中的下行输出功率值和背景技术中阐述的功率等级相一致；
在其中一个实施例中，获取下行输出功率值的方式可以是：根据连接所述远端机的光接口的ID(IDentity的缩写，身份标识号码)标识向所述远端机发送功率查询指令，接收所述远端机根据所述查询指令返回的下行输出功率值；
其中，根据远端机与中继端机之间的通信协议，可以获得连接远端机的光接口的ID标识，不同的远端机的ID标识不同，通过该ID标识可以向该ID标识对应的远端机发送功率查询指令，远端机接收到该功率查询指令后向中继端机返回该远端机的下行输出功率值；
本实施例中的上行最大增益值是预先设置的定值，在实际设置时，可以综合考虑通信规范、杂散损耗等因素，该上行最大增益值需要大于任意一个规划接入有源DAS系统的远端机对应的上行增益的最大值；
步骤S102：结合所述下行输出功率值、所述上行最大增益值获得所述远端机所在上行链路需要设置的衰减调节值；
在其中一个实施例中，获得衰减调节值的方式可以是：根据所述下行输出 功率值在预先建立的对照表中查询与该下行输出功率值对应的中继端上行增益，计算所述上行最大增益值与所述中继端上行增益的差值，将该差值作为所述衰减调节值；
其中，对照表表征的是下行输出功率值与中继端上行增益的一一对应关系，如表1所示，是对照表的示意表格，其中，表格中的下行输出功率值的个数、数值以及所对应的中继端上行增益都可以根据实际设计需要设置；该对照表可以根据远端机、中继端机的具体配置信息进行设置；
表1 下行输出功率值与中继端上行增益的对照表
下行输出功率值 中继端上行增益
P1 Gain1
P2 Gain2
P3 Gain3
P4 Gain4
步骤S103：根据所述衰减调节值对所述上行链路中的可调衰减器进行设置；
根据所述衰减调节值对所述上行链路中的可调衰减器进行设置是指，将相应上行链路中的可调衰减器的衰减值调节至衰减调节值。
根据上述本发明的方案，其是获取接入有源DAS系统的远端机的下行输出功率值，并获取所述有源DAS系统的中继端机的上行最大增益值，结合所述下行输出功率值、所述上行最大增益值获得所述远端机所在上行链路需要设置的衰减调节值，根据该衰减调节值对所述上行链路中的可调衰减器进行设置，由于是基于远端机的下行输出功率值对相应上行链路中的可调衰减器进行设置，而每个上行链路都可以按照本发明方案对相应上行链路中的可调衰减器进行设置，因此，对于下行输出功率值各不相同的远端机所在上行链路的增益也各不相同，实现了对不同功率等级的远端机的兼容，简化了覆盖方案设计的复杂度，增加了网络建设的灵活度，降低了网络建设成本。
参见图2所示，是传统的有源DAS系统的结构示意图。如图2所示，有源DAS系统的中继端机与各远端机之间的光接收是独立的，光收发模块的接收端具有独立的射频放大器RF1～RF4和可调衰减器ATT1～ATT4；由于中继端机 不能兼容不同功率等级的远端接的接入，使得其覆盖方案设计比较复杂。图2中的标号为“PD”的器件指光探测器，标号为“WDM”的器件指波分复用器，标号为“LD”的器件指激光器，OP1～OP4为四个不同的光接口，标号为“RF5”的器件指射频放大器。
参照图2所示，以下以当前有两台不同功率等级的远端机(RU1、RU2)接入中继端机、RU1为大功率远端机、RU2为小功率远端机(即RU1的下行输出功率值比RU2的下行输出功率值大)为例对本发明的方案进行阐述。
其中，有源DAS系统的中继端机的上行最大增益值设计为Gain1，当接入大功率远端机RU1时，有源DAS系统的中继端机上行链路增益设计为Gain2；当接入小功率远端机RU2时，有源DAS系统的中继端机上行链路增益设计为Gain3，其中Gain1≥Gain2，Gain1≥Gain3。
当大功率远端机RU1接入中继端机时，中继端机通过内建的通信通道查询到远端机RU1的下行输出功率值，并通过查找对照表查询到该下行输出功率值对应的中继终端增益为Gain2(需预先将远端机RU1的下行输出功率值与Gain2的对应关系设置在对照表中)，进而计算出中继端机上行链路需要设置的衰减调节值Att1＝Gain1-Gain2，中继端机将Att1的值传递给光收发模块对可调衰减器ATT1进行设置。
当小功率远端机RU2接入中继端机时，中继端机会通过内建的通信通道查询到远端机的下行输出功率值，并通过查找对照表查询到该下行输出功率值对应的中继终端增益为Gain3(需预先将远端机RU2的下行输出功率值与Gain3的对应关系设置在对照表中)，进而计算出中继端机上行链路需要设置的衰减调节值Att2＝Gain1-Gain3，中继端机将Att 2的值传递给光收发模块对可调衰减器ATT2进行设置。
在上述阐述中，不同的上行链路所对应的上行最大增益值相同(都为Gain1)，这种方式可以简化算法、提高控制效率。但需要说明的是，并不限于不同的上行链路所对应的上行最大增益值相同的方式，根据实际需要，也可以将不同的上行链路所对应的上行最大增益值设为不同值，则在计算可调衰减值时所用的上行最大增益值应与上行链路相对应。
综上可知，通过中继端机对远端机的自动获取下行输出功率值对接入不同下行输出功率值的不同上行链路通路进行增益的自动独立设置，从而实现对大小功率远端机的兼容接入。
根据上述本发明的有源DAS系统中继端增益控制方法，本发明还提供一种有源DAS系统中继端增益控制装置，以下就本发明的有源DAS系统中继端增益控制装置的实施例进行详细说明。图3中示出了本发明的有源DAS系统中继端增益控制装置的实施例的结构示意图。为了便于说明，在图3中只示出了与本发明相关的部分。
如图3所示，本实施例中的有源DAS系统中继端增益控制装置，包括获取模块201、处理模块202、控制模块203，其中：
获取模块201，用于获取接入有源DAS系统的远端机的下行输出功率值，并获取所述有源DAS系统的中继端机的上行最大增益值；
