和对射频处理单元的测试可以不依赖于现有基站系统而独立完成， 减少额 外的辅助工作。
参照图 4， 图 4是本发明装置的第二实施例结构示意图：
为了方便对信息及数据处理结果的监测 , 在测试时将数据处理结果及 接口状态、 与该装置接口设备的工作状态显示出来， 在图 3所示装置的基 础上增加了与控制单元 221相连的显示接口单元 24，通过该显示接口单元 可以实时显示相关信息。 例如 CPRI (通用公共无线接口）协议中规定了 状态位、 告警位和通信信令链路， 可以通过传输接口单元 23获得这些信 息， 然后通过显示接口单元 24显示这些信息； 另外， 还可以通过控制单 元 221实时显示可编程逍辑单元 222的处理结果。 控制单元作为该装置的 核心控制部分， 它和各单元之间有通信接口， 例如数据总线、 串口等。 控 制单元会不断获取该装置中各个部分的信息， 包括可编程逻辑单元 222和 执行 CPRI或 OBSAI协议的传输接口单元 23的工作状态、 处理结果等， 由控制单元 221控制将这些信息通过显示接口单元显示出来。
利用上述本发明无线基站系统调测辅助接口装置可以简单地实现对 基站系统的测试。
本发明系统的组网图如图 5所示：
包括： 调测终端 51、 基站被测单元 53 , 分别耦合于基站被测单元和 调测终端的调测辅助接口装置 52，用于辅助调测终端完成对基站被测单元 的测试。
基站被测单元可以是基站系统中的基带处理单元， 也可以是基站系统 中的射频处理单元， 通过调测辅助接口装置 52可以实现对基站系统中的 基带处理单元或射频处理单元的独立测试， 不需要实际系统中的基带处理 单元和射频处理单元相互辅助， 而是由调测辅助接口装置 52模拟其功能 来实现。
在调测时， 首先由用户通过调测终端发送测试命令， 调测辅助接口装 置 52通过计算机接口单元 51接收测试命令， 并通过传输接口单元 23接 收基站被测单元 53发送的数据， 然后由数据处理单元 22根据测试命令对 接收的数据进行相应的处理； 然后将处理结果通过计算机接口单元 21传
送到调测终端 51 , 调测终端 51对这些处理结果进行分析, 获得最终的测 试结果。 图 6示出了对基带处理单元进行测试时的测试系统组网图： 调测终端 51由普通计算机来实现， 通过调测辅助接口装置 52与基带 处理单元 61相连。
由该图可见， 对基带处理单元 61进行测试时， 不需要实际系统的射 频处理单元参与辅助工作， 而是由调测辅助接口装置 52来模拟实现射频 处理单元的处理功能， 配合基带处理单元完成基带信号的调制 /解调、发送 /接收等操作。 调测终端 51对调测辅助接口装置 52的处理结果进行分析， 获取测试结果。
比如， 在现场， 基站设备出现故障， 需要采集基带和射频之间的数据 进行分析和处理， 或者需要分析测试基带处理部分是否正常， 可以将本发 明装置连接到基带处理单元上， 和基带处理单元建立连接， 模拟射频处理 单元的功能， 完成上述测试功能。
在开发调试中， 射频处理部分可能比基带处理部分开展得慢， 调试基 带处理单元需要用到射频处理部分配合时， 射频处理部分还不能到位， 此 时可以由接口设备直接和基带处理建立业务通道， 进行调试。
图 7示出了对射频处理单元进行测试时的测试系统组网图： 调测终端 51由普通计算机来实现， 通过调测辅助接口装置 52与射频 处理单元 62相连。
由该图可见， 对射频处理单元进行测试时， 不需要实际系统的基带处 理单元参与辅助工作， 而是由调测辅助接口装置 52来模拟实现基带处理 单元的处理功能，配合射频处理单元完成高频信号的变频、系统时钟提取、 语音信号编解码等。 调测终端对调测辅助接口装置 52的处理结果进行分 析， 获取测试结果。
比如， 在现场， 基站设备出现故障， 需要采集基带和射频之间的数据 进行分析和处理， 或者需要给射频处理单元输入特殊测试数据， 即需要基 带处理单元所不支持的灵活的测试功能。 这时， 可以断开基带处理单元和
射频处理单元之间的连接， 通过本发明装置将调测终端连接到射频处理单 元上， 完成上述测试功能。
而且， 在开发调试中， 基带处理部分可能比射频处理部分开展得慢， 调试射频处理单元需要用到基带处理部分配合时， 基带处理部分还不能到 位， 此时可以通过本发明装置直接和射频处理单元建立业务通道， 进行调 试。
虽然通过实施例描绘了本发明， 本领域普通技术人员知道， 本发明有 许多变形和变化而不脱离本发明的精神， 希望所附的权利要求包括这些变 形和变化而不脱离本发明的精神。
