Description

测试方法、装置及系统
本申请要求于2019年09月23日提交中国专利局、申请号为201910901411.0、申请名称为“测试方法、装置及系统”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请实施例涉及通信领域，尤其涉及一种测试方法、装置及系统。
背景技术
目前市场上的终端设备涉及多种通信协议，比如长期演进(long term evolution，LTE)、宽带码分多址(wideband code division multiple access，WCDMA)、全球移动通信系统(global system for mobile communications，GSM)、时分-同步码分多址(time division-synchronous code division multiple access，TD-SCDMA)、无线局域网(wireless local area network，WLAN)、蓝牙等协议。随着5G等下一代通信协议的加入，终端设备将需要支撑越来越多的通信协议，这对不同通信协议下终端设备的通信功能的测试测试效率提出了很高的挑战。
现有技术中，对于通信功能的测试包括有扫频调谐式测试方法和单协议快速傅里叶变换测试方法。在扫频调谐式测试方法中，终端设备可以通过改变下变频混频器的本地振荡器频率，使得输入待测信号的频率与本振频率之差等于需要的固定中频；后续的，再使用带通滤波器由中频信号中取出所需的差频，进行待测信号的测试与分析。在单协议快速傅里叶变换测试方法中，测试设备将待测信号在时域中数字化后执行快速傅里叶变换来求出频谱。随后，测试设备中的低通滤波器将待测信号除去测量范围之外的高频分量，再对波形进行取样进行模拟到数字转换。随后，测试设备中的微处理器接收取样波形，利用快速傅里叶变换计算波形的频谱。
然而，扫频调谐式测试方法，硬件系统复杂，仅适用单协议非实时测量，多于大批量多协议的测试速度较慢。单协议快速傅里叶变换测试方法，与前端射频器件特性深耦合，对于多协议终端设备的大规模测试，只能串行测试每个协议，中间需要对射频前端重新配置，测试的时间随着测试协议的增多成倍增长。因此，上述两种现有的通信功能的测试方法，对于多协议终端设备的通信功能的测试速度较慢。

具体实施方式
目前市场上的终端设备涉及多种通信协议，比如长期演进(long term evolution，LTE)、宽带码分多址(wideband code division multiple access，WCDMA)、全球移动通信系统(global system for mobile communications，GSM)、时分-同步码分多址(time division-synchronous code division multiple access，TD-SCDMA)、无线局域网(wireless local area network，WLAN)、蓝牙等协议。随着5G等下一代通信协议的加入，终端设备将需要支撑越来越多的通信协议，这对不同通信协议下终端设备的通信功能的测试效率提出了很高的挑战。
现有技术中，对于终端设备的通信功能的测试包括有扫频调谐式测试方法和单协议快速傅里叶变换测试方法。在扫频调谐式测试方法中，终端设备可以通过改变下变频混频器的本地振荡器频率，使得输入待测信号的频率与本振频率之差等于需要的固定中频；后续的，再使用带通滤波器由中频信号中取出所需的差频，进行待测信号的测试与分析。在单协议快速傅里叶变换测试方法中，测试设备将待测信号在时域中数字化后执行快速傅里叶变换来求出频谱。随后，测试设备中的低通滤波器将待测信号除去测量范围之外的高频分量，再对波形进行取样进行模拟到数字转换。随后，测试设备中的微处理器接收取样波形，利用快速傅里叶变换计算波形的频谱。然而，扫频调谐式测试方法，硬件系统复杂，仅适用单协议非实时测量，多于大批量多协议的测试速度较慢。单协议快速傅里叶变换测试方法，与前端射频器件特性深耦合，对于多协议终端设备的大规模测试，只能串行测试每个协议，中间需要对射频前端重新配置，测试的时间随着测试协议的增多成倍增长。因此，上述两种现有的通信协议的测试方法，对于多协议终端设备的测试速度较慢。
为了解决上述问题，本申请实施例提供一种测试方法、装置及系统，以现实多个通信协议的并行化测试，显著提高终端设备通信功能的测试效率。

在本申请实施例中，终端设备可以包括有至少两个通信协议，每种通信协议对应一个测试信号。在终端设备生成上行射频信号时，可以对通信协议对应的测试信号进行叠加，进而生成包含了多种测试信息的上行射频信号。
示例性的，终端设备可以包括有4G协议、5G协议、WiFi协议和比特流(bit torrent，BT)协议四种通信协议，每种协议对应了一个测试信号。因此，终端设备向测试设备发送的上行射频信号，由4G协议、5G协议、WiFi协议和BT协议对应的测试信号叠加生成。

本申请实施例对于如何根据测试信号对应的测试子结果确定终端设备的上行测试结果也不做限制，在一种可选的实施方式中，若任意测试信号对应的测试子结果不合格，则上行测试结果不合格，在另一种可选的实施方式中，若测试信号对应的测试子结果不合格的数量超过阈值，则上行测试结果不合格。
本申请实施例中，在提取至少两个测试信号后，测试设备可以将测试信号分发到对应的测试模块中，从而使得测试信号可以并向测试。现有技术中，协议兼容性多通过单个协议带外泄露等指标间接测量，在本申请实施例中，可通过多协议并行下各自指标测量直接评估多协议兼容性。
