具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别不同对象，而不是用于描述特定顺序。此外，术语“包括”和“具有”以及它们任何变形，意图在于覆盖不排他的包含。例如包含了一系列步骤或单元的过程、方法、系统、产品或设备没有限定于已列出的步骤或单元，而是可选地还包括没有列出的步骤或单元，或可选地还包括对于这些过程、方法、产品或设备固有的其他步骤或单元。
在本文中提及“实施例”意味着，结合实施例描述的特定特征、结构或特性可以包含在本发明的至少一个实施例中。在说明书中的各个位置出现该短语并不一定均是指相同的实施例，也不是与其它实施例互斥的独立的或备选的实施例。本领域技术人员显式地和隐式地理解的是，本文所描述的实施例可以与其它实施例相结合。
本发明实施例公开了一种射频性能测试方法、装置及用户终端，用于实现 快捷地完成射频性能测试，提高测试的可操作性，并降低测试成本。以下分别进行详细说明。
其中，本发明实施例中所描述的用户终端可以是具备双客户识别模块(Subscriber Identity Module，SIM)卡槽的智能手机、平板电脑、移动互联网设备(Mobile Internet Devices，MID)、穿戴式设备等，每个SIM卡槽有与其对应的调制解调器和天线。
请参阅图1，为本发明实施例提供的一种射频性能测试方法的流程示意图。本实施例中所描述的射频性能测试方法，应用于用户终端，该用户终端包括第一调制解调器和第二调制解调器，该第一调制解调器与第一天线连接，该第二调制解调器与第二天线连接，该方法包括：
101、用户终端通过第一天线发射第一调制解调器产生的频率为f0、功率为PS的调制信号。
其中，为保证第一天线和第二天线之间可以同频接收其中一方发射的调制信号，关于频率f0的选取如下：
根据3GPP协议中TS 36.521-1 V12.3.0(2014-09)5.2章节对通信工作频段的定义，频分双工(Frequency Division Duplex，FDD)频段包括：Band1～Band31，时分双工(Time Division Duplex，TDD)频段包括：Band33～Band43。
对于FDD频段，对应的上行频段与下行频段有重合的区域即可以作为f0的选取，例如Band1的上行频段为1920MHz～1980MHz，Band2的下行频段为1930MHz～1990MHz，重合区域为1930MHz～1980MHz，则f0即可在1930MHz～1980MHz中选取，按照上述选取规则，FDD频段中适合f0选取的频段如下：
1930MHz～1980HMz，
1850MHz～1880HMz，
880MHz～894HMz，
852MHz～862HMz，
734MHz～746HMz；
对于TDD频段，由于上行和下行同频，故所有TDD频段都适合f0选取， 包括：
1900MHz～1920MHz，
2010MHz～2025MHz，
1850MHz～1910MHz，
1930MHz～1990MHz，
1910MHz～1930MHz，
2570MHz～2620MHz，
1880MHz～1920MHz，
2300MHz～2400MHz，
2496MHz～2690MHz，
3400MHz～3600MHz，
3600MHz～3800MHz，
703MHz～803MHz；
具体的，该用户终端上可以安装有专门的应用程序，由人工通过该应用程序触发射频性能测试流程，或者该应用程序根据设置自动周期性地触发射频性能测试流程。该用户终端根据该应用程序的控制指令控制该第一调制解调器产生频率为f0、功率为PS的调制信号，再通过与该第一调制解调器连接的该第一天线发射出去。
在一些可行的实施方式中，该应用程序的功能也可以集成到该用户终端的系统功能中，从而在系统功能的选项中也可以触发射频性能测试流程。
在一些可行的实施方式中，该用户终端也可以与一控制主机(例如PC)建立连接，通过该控制主机向该用户终端发送指令以触发射频性能测试流程。
102、该用户终端通过第二天线用该f0接收该调制信号，获取第二调制解调器收到的该调制信号的功率PR。
具体的，该调制信号通过该第一天线发射出去后，该用户终端利用第二天线对该调制信号做同频接收，并获取该调制信号从该第二天线传输到该第二调制解调器时的功率PR。
103、该用户终端根据该PS、该PR、该调制信号的路径损耗PL和该第一天线与该第二天线之间在该f0处的隔离度LV确定该用户终端的射频性能。
其中，PL包括该调制信号从该第一调制解调器到该第一天线的路径损耗和该调制信号从该第二天线到该第二调制解调器的路径损耗。PL和LV可以通过测量事先获取，在该第一天线和该第二天线的馈电处分别焊接射频线缆，以保证50欧姆Ω的阻抗匹配，通过网络分析仪连接该第一天线和该第二天线的射频线缆，该网络分析仪在f0处测得的S参数中S12参数即为该第一天线和该第二天线之间的LV。通过频谱仪等仪表可以获取调制信号在被该第一天线发射前从该第一调制解调器到该第一天线过程中产生的路径损耗，以及该调制信号在被该第二天线接收后从该第二天线接收到该第二调制解调器过程中产生的路径损耗，这两个路径损耗之和即可作为PL。
其中，该用户终端的射频性能主要包括两方面：是否存在射频故障，以及射频性能一致性是否存在问题。其中，射频故障一般由元器件损坏、电路开路/短路等因素引起，导致调制信号在传输过程中功率大幅衰减，甚至传输中断。而射频性能一致性一般由元器件制造工艺的细微差别引起，制造工艺的细微差别会使得元器件的实际参数与理论参数有一定差别，进而导致调制信号在传输过程中功率有小幅衰减或增加。
其中，针对射频故障预设第一功率阈值，针对射频性能一致性预设第二功率阈值，该预设第一功率阈值大于该预设第二功率阈值，假设该预设第一功率阈值为5dB，该预设第二功率阈值为2dB。
具体的，该用户终端根据该第一调制解调器产生该调制信号的功率PS、该调制信号的路径损耗PL和该第一天线与该第二天线之间在该f0处的隔离度LV获取理论上该第二调制解调器应该收到的该调制信号的功率PS-PL-LV，并获取实际上该第二调制解调器收到的该调制信号的功率PR，得出理论上该第二调制解调器应该收到的该调制信号的功率PS-PL-LV与实际上该第二调制解调器收到的该调制信号的PR的差值的绝对值|PS-PL-LV-PR|。
进一步的，如果|PS-PL-LV-PR|大于或等于5dB(即该预设第一功率阈值)，即实际上该第二调制解调器收到的该调制信号的功率与理论上该第二调制解调器应该收到的该调制信号的功率相差过大，则该用户终端可以确定自身存在射频故障。如果|PS-PL-LV-PR|大于或等于2dB(即该预设第二功率阈值)，并且小于5dB，即实际上该第二调制解调器收到的该调制信号的功率与理论上该 第二调制解调器应该收到的该调制信号的功率相差较大，则该用户终端可以确定自身存在射频性能一致性问题。如果|PS-PL-LV-PR|小于2dB，即实际上该第二调制解调器收到的该调制信号的功率与理论上该第二调制解调器应该收到的该调制信号的功率相差很小，则该用户终端可以确定自身的射频性能良好，不存在射频故障和射频性能一致性问题。
进一步的，该用户终端在确定自身存在射频故障或射频性能一致性问题时，可以生成日志文件进行记录以便于后续检验该用户终端的射频性能，维修时的故障初步判断等。此外，该用户终端还可以通过扬声器发出声音信号、通过指示灯发出光信号、通过振动马达产生振动、在用户界面输出提示框等方式输出该用户终端存在射频故障或射频性能一致性问题的提示信息。
本发明实施例中的用户终端包括第一调制解调器和第二调制解调器，该第一调制解调器与第一天线连接，该第二调制解调器与第二天线连接，该用户终端利用该第一调制解调器产生频率为f0、功率为PS的调制信号，通过该第一天线将该调制信号发射出去，再通过该第二天线用f0对该调制信号进行同频接收，获取该第二调制解调器收到的该调制信号的功率PR，进而根据该PS、该PR、该调制信号的路径损耗PL和该第一天线与该第二天线之间在f0处的隔离度LV得出理论上该第二调制解调器应该收到的该调制信号的功率PS-PL-LV与实际上该第二调制解调器收到的该调制信号的PR的差值的绝对值|PS-PL-LV-PR|，通过将|PS-PL-LV-PR|与预设第一功率阈值和预设第二功率阈值比较以确定该用户终端是否存在射频故障或射频性能一致性问题。可见，用户终端通过自发自收调制信号，再根据调制信号的发射功率和接收功率即可确定自身的射频性能，从而实现快捷地完成射频性能测试，提高测试的可操作性，并降低测试成本。

其中，该预设第一功率阈值大于该预设第二功率阈值。
该装置还包括：
生成模块205，用于在该|PS-PL-LV-PR|大于或等于该预设第一功率阈值时，生成该用户终端存在射频故障的日志文件，和/或，输出模块206，用于输出该用户终端存在射频故障的指示信息。
该生成模块205，还用于在该|PS-PL-LV-PR|大于或等于该预设第二功率阈值，且小于该预设第一功率阈值时，生成该用户终端存在射频性能一致性问题的日志文件，和/或，该输出模块206，还用于输出该用户终端存在射频性能一致性问题的指示信息。

第二天线1004，用于用f0接收该调制信号。
处理器1010，用于获取第二调制解调器1002收到的该调制信号的功率PR。
处理器1010，还用于根据该PS、该PR、该调制信号的路径损耗PL和该第一天线1003与该第二天线1004之间在该f0处的隔离度LV确定该用户终端的射频性能。
具体的，该处理器1010根据该PS、该PR、该调制信号的路径损耗PL和该第一天线1003与该第二天线1004之间在该f0处的隔离度LV确定该用户终端的射频性能的具体方式为：
获取PS-PL-LV与该PR的差值的绝对值|PS-PL-LV-PR|。
在该|PS-PL-LV-PR|大于或等于预设第一功率阈值时，确定该用户终端存在射频故障。
在该|PS-PL-LV-PR|大于或等于预设第二功率阈值，且小于该预设第一功率阈值时，确定该用户终端存在射频性能一致性问题。
其中，该预设第一功率阈值大于该预设第二功率阈值。
该处理器1010，还用于在该|PS-PL-LV-PR|大于或等于该预设第一功率阈值时，生成该用户终端存在射频故障的日志文件，和/或，输出设备1007，用于输出该用户终端存在射频故障的指示信息。
该处理器1010，还用于在该|PS-PL-LV-PR|大于或等于该预设第二功率阈值，且小于该预设第一功率阈值时，生成该用户终端存在射频性能一致性问题的日志文件，和/或，该输出设备1007，还用于输出该用户终端存在射频性能一致性问题的指示信息。
本发明实施例中，该第一调制解调器1011产生频率为f0、功率为PS的调制信号，该第一天线1003将该调制信号发射出去，该第二天线1004用f0对该调制信号进行同频接收，该处理器1010获取该第二调制解调器1002收到的该调制信号的功率PR，进而根据该PS、该PR、该调制信号的路径损耗PL和该第一天线1003与该第二天线1004之间在f0处的隔离度LV得出理论上该第二调制解调器1002应该收到的该调制信号的功率PS-PL-LV与实际上该第二调制解调器1002收到的该调制信号的PR的差值的绝对值|PS-PL-LV-PR|，通过将|PS-PL-LV-PR|与预设第一功率阈值和预设第二功率阈值比较以确定该用户终 端是否存在射频故障或射频性能一致性问题。可见，用户终端通过自发自收调制信号，再根据调制信号的发射功率和接收功率即可确定自身的射频性能，从而实现快捷地完成射频性能测试，提高测试的可操作性，并降低测试成本。
