具体实施方式
在本发明实施例中，终端获取终端的射频功率放大器的当前供电电压值；终端根据所述射频功率放大器的发射功率与供电电压的对应关系，以及当前供电电压值，获得射频功率放大器的当前发射功率值；终端将射频功率放大器的当前发射功率值作为终端的当前发射功率。
下面结合附图和具体实施例，对本发明进一步详细说明。
图1为本发明实施例提供的一种发射功率检测方法的流程示意图，如图1所示，该方法包括：
步骤101：获取终端的射频功率放大器的当前供电电压值。
具体地，本步骤可以包括，在终端正常工作过程中，终端读取其射频功率放大器(PA，Power Amplifier)的供电模块的电压寄存器中的值；终端根据电压寄存器中的值换算获得其射频功率放大器的当前供电电压值。或者，本步骤也可以为，在终端正常工作过程中，终端通过测量其射频功率放大器的当前供电电压，获得其射频功率放大器的当前供电电压值。需说明的是，所述射频功率放大器的供电模块可以为DCDC(Direct Current，直 流)转换芯片；即射频功率放大器的供电可以由DCDC转换芯片提供。
需说明的是，在终端正常工作过程中，终端可以根据其射频功率放大器的发射功率值的变化调整其射频功率放大器的供电电压值。具体地，由于在射频功率放大器的功率增益值不变的情况下，存在最低的供电电压值，可以使得射频功率放大器的发射功率维持在对应的发射功率值，如，若在射频功率放大器的功率增益值为3分贝时，射频功率放大器的供电电压值的取值在1.5伏至3.4伏范围，均可以使得射频功率放大器的发射功率维持在功率增益值3分贝对应的10毫瓦，即可以确定出使得射频功率放大器的发射功率维持在功率增益值3分贝对应的10毫瓦，所需的最低供电电压值为1.5伏，因此为了降低终端功耗，进而降低终端耗电量，提高射频功率放大器的效率，终端可以在其射频功率放大器的发射功率值变化时，调整射频功率放大器的供电电压值。
具体地，所述终端根据其射频功率放大器的发射功率值的变化调整其射频功率放大器的供电电压值，可以为，终端根据其射频功率放大器的发射平均功率值的变化调整其射频功率放大器的供电电压值；即终端可以根据其射频功率放大器的发射平均功率值来动态的调整其射频功率放大器的供电电压值。如，终端可以采用平均功率追踪(APT，Average Power Tracking)技术，来实现根据射频功率放大器的发射平均功率值来动态的调整射频功率放大器的供电电压值。或者，所述终端根据其射频功率放大器的发射功率值的变化调整其射频功率放大器的供电电压值，可以为，终端根据其射频功率放大器的当前发射功率值的变化调整其射频功率放大器的供电电压值。
步骤102：根据射频功率放大器的发射功率与供电电压的对应关系，以及当前供电电压值，获得射频功率放大器的当前发射功率值；将射频功率放大器的当前发射功率值作为终端的当前发射功率。
如此，无需为终端增加任何硬件便能检测出终端的发射功率，简单方便，能实时地检测出终端的发射功率。
具体地，本步骤可以包括，终端获取其射频功率放大器的发射功率与供电电压的对应关系，获得射频功率放大器的当前功率增益值对应的发射功率值，及该发射功率值对应的供电电压值；终端从对应的供电电压值中查找出第一供电电压值及第二供电电压值；所述第一供电电压值为在对应的供电电压值中，小于当前供电电压值的供电电压值；所述第二供电电压值为在对应的供电电压值中，大于或等于当前供电电压值的供电电压值；终端根据第一供电电压值及第二供电电压值，第一供电电压值对应的发射功率值及第二供电电压值对应的发射功率值，以及当前供电电压值，进行插值运算获得射频功率放大器的当前发射功率值；接着终端即可以将获得的射频功率放大器的当前发射功率值作为终端的当前发射功率。
这里，举例说明上述过程，如，获得的当前功率增益值对应的发射功率值可以为，P1、P2、Pi、Pi+1，这些发射功率值对应的供电电压值可以为，V1、V2、Vi、Vi+1，获取到的终端的射频功率放大器的当前供电电压值可以为V；查找出的第一供电电压值可以为Vi，查找出的第二供电电压值可以为Vi+1，其中，Vi<V≤Vi+1；则所述终端根据第一供电电压值及第二供电电压值，第一供电电压值对应的发射功率值及第二供电电压值对应的发射功率值，以及当前供电电压值，进行插值运算获得的射频功率放大器的当前发射功率值为，
Figure PCTCN2015094018-appb-000001
从而计算获得射频功率放大器的当前发射功率值为P，即终端的当前发射功率为P。
具体地，或者本步骤可以包括，终端获取其射频功率放大器的发射功率与供电电压的对应关系，获得射频功率放大器的当前功率增益值对应的发射功率值，及该发射功率值对应的供电电压值；终端判断对应的供电电压值中是否存在与当前供电电压值相同的供电电压值；在对应的供电电压 值中不存在与当前供电电压值相同的供电电压值时，终端从对应的供电电压值中查找出第一供电电压值及第二供电电压值；所述第一供电电压值为在对应的供电电压值中，小于当前供电电压值的供电电压值；所述第二供电电压值为在对应的供电电压值中，大于或等于当前供电电压值的供电电压值；终端根据第一供电电压值及第二供电电压值，第一供电电压值对应的发射功率值及第二供电电压值对应的发射功率值，以及当前供电电压值，进行插值运算获得射频功率放大器的当前发射功率值；在对应的供电电压值中存在与当前供电电压值相同的供电电压值时，终端确定出与该供电电压值对应的发射功率值；终端将该发射功率值作为射频功率放大器的当前发射功率值；接着终端即可以将获得的射频功率放大器的当前发射功率值作为终端的当前发射功率。
其中，所述射频功率放大器的发射功率与供电电压的对应关系的获取过程，可以包括，终端读取其射频功率放大器的当前功率增益值；终端从已生成的电压功率映射表中，读取出当前功率增益值对应的发射功率值，及该发射功率值对应的供电电压值；所述电压功率映射表按照对应关系记录了射频功率放大器的功率增益值、发射功率值及其对应的供电电压值，如图2所示。即可以预先生成电压功率映射表，该电压功率映射表按照对应关系记录了射频功率放大器的功率增益值、发射功率值及其对应的供电电压值，并可以将该电压功率映射表存储在终端，在终端需获取射频功率放大器的发射功率与供电电压的对应关系时，终端即可从射频功率放大器的功率增益寄存器中，读取其射频功率放大器的当前功率增益值，从已生成的电压功率映射表中，读取出该当前功率增益值对应的发射功率值，及该发射功率值对应的供电电压值。
需说明的是，所述电压功率映射表的生成过程可以包括，测量装置设置终端的射频功率放大器的功率增益值及供电电压值；在不同的功率增益 值及供电电压值下，测量装置测量射频功率放大器的发射功率值；测量装置分别确定出在功率增益值不变的情况下，使得射频功率放大器的发射功率维持在各个发射功率值，所需的最低的供电电压值；测量装置将确定出的最低的供电电压值作为与各个发射功率值对应的供电电压值；测量装置按照对应关系分别将功率增益值、发射功率值及其对应的供电电压值记录在电压功率映射表中。
需说明的是，为了便于生成每个终端的电压功率映射表，在已生成了一个终端的电压功率映射表后，可以将该电压功率映射表作为标准的电压功率映射表，在生成同类的其它终端的电压功率映射表时，测量装置可以依据该标准的电压功率映射表，对相应的终端进行测量，并对该标准的电压功率映射表中所记载的值进行校准，获得相应终端的电压功率映射表，从而使得每个终端的电压功率映射表所记载的值更加准确。
需说明的是，所述电压功率映射表的生成过程，可以在终端出厂前进行。所述电压功率映射表可以存储在终端的非易失随机存取存储器(NV RAM，Nonvolatile Random-Access Memory)中。
