Description

一种射频输出功率配置方法、装置、电子芯片和电子设备 技术领域
本申请涉及通信技术领域，特别涉及一种射频输出功率配置方法、装置、电子芯片和电子设备。
背景技术
比吸收率(Specific Absorption Rate，SAR)是测量在使用手机等无线通信产品时人体暴露部分所接收的辐射RF能量。SAR测试能够评估在距人体近距离范围内使用低功率发射器的安全性。针对不同频段，人体吸收的电磁波比率都有区别。SAR值指标调整，实际上就是调整不同频段下无线通信产品的最大发射功率，以使得SAR值满足官方标准。
SAR值指标调整通常根据终端的硬件实现。具体的，根据SAR测试场景要求、指标要求，调整射频器件各频段的发射功率(输出功率)(一般相较于最大发射功率降低，也就是发射功率回退)。例如，在手机的非易失内存里面存储一组各制式下各频段的功率回退值，根据手机当前的通信制式以及通信频段调用对应的功率回退值，根据调用的功率回退值配置手机的射频器件。
然而，在实际应用场景中，SAR值在各地区、各国家均有不同的测试标准，包括测试方法(从最简单的测试采用听筒接听状态下的手持通话模型、耳机接听等)、指标要求(例如，欧盟要求2W/Kg(10g average)；韩国的要求为1.6W/Kg(1g average)等)。这就导致通信产品，要么只能适应一个地区/国家的标准；要么只能对多个地区/国家的标准采用公约的方式兼容，将通信产品限定在最低的标准。这不仅大大降低了通信产品的应用场景灵活性，并且，在很多地区/国家中，通信产品无法实现当前地区/国家的标准下的最高无线性能。
发明内容

具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合本申请具体实施例及相应的附图对本申请技术方案进行清楚、完整地描述。显然，所描述的实施例仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，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，都属于本申请保护的范围。
本申请的实施方式部分使用的术语仅用于对本申请的具体实施例进行解释，而非旨在限定本申请。
SAR值指标调整的目的是使得SAR值满足当前地区/国家的标准。具体的，通过功率设定参数值调整射频器件(例如，实现蜂窝移动通信的射频器件)的输出功率，从而使得SAR值满足当前地区/国家的标准。例如，功率设定参数值为功率回退值，在射频器件的最大输出功率的基础上降低输出功率(降低值为功率回退值)。又例如，功率设定参数值为最大功率值，将在射频器件的输出功率设定为最大功率值。
对应SAR值在不同地区/国家的标准，设定射频器件的输出功率所要选用的功率设定参数值也就不同。因此，如果预先保存不同地区/国家的标准所对应的功率设定参数值，在通信设备工作时，根据其所处的地区/国家调用对应的功率设定参数值配置射频器件。这样，就可以使得通信设备可以工作在不同的地区/国家。
进一步的，在实际应用场景中，针对不同无线通信制式、不同的无线通信频段，人体吸收的电磁波比率都有区别，因此，针对同一SAR值，当通信设备工作的频段不同时， 满足该SAR值的输出功率也就不同，配置射频器件时所采用的功率设定参数值也就不同。因此，在预先保存功率设定参数值时，还需要考虑不同的频段。
因此，在本申请一实施例中，预先保存不同地区/国家的各个制式、各个频段所对应的功率设定参数值。在通信设备工作时，获取通信设备当前的驻网信息，根据驻网信息确认通信设备当前的无线通信制式、通信设备当前使用的无线信号频段；并且，根据驻网信息确认通信设备所接入的当地通信网络，根据通信设备所接入的当地通信网络来确认通信设备当前所处的国家/地区。根据通信设备当前所处的国家/地区、通信设备当前的无线通信制式以及通信设备当前使用的无线信号频段调用对应的功率设定参数值，使用调用的功率设定参数值配置射频器件的输出功率。
进一步的，在实际应用场景中，在输出功率一定的前提下，不同的通信设备应用场景中，测量到的SAR值是不同的。例如，在输出功率一定的前提下，用户手持手机使用手机接听通话的应用场景中，与用户使用连接到手机的耳机接听通话的应用场景中，测量到的SAR值是不同的。并且，在用户利用蜂窝移动通信技术实现通话的过程中，手机的无线(WiFi)和/或蓝牙处于开启状态的应用场景中，与手机的无线(WiFi)和/或蓝牙处于关闭状态的应用场景中，测量到的SAR值也是不同的。因此，在本申请一实施例中，在预先保存功率设定参数值时，还需要考虑不同的应用场景。而在通信设备工作，需要调用功率设定参数值时，也需要首先分析通信设备当前的应用场景，调用与应用场景对应的功率设定参数值。
进一步的，在实际应用场景中，某些通信运营商制定了自身的SAR值标准。并且，当通信设备为测试设备(例如，通信设备的SIM卡为不属于任何运营商的测试卡)，不属于任何通信运营商时，通信设备还必须符合测试设备所特定的SAR值标准。因此，在本申请一实施例中，在预先保存功率设定参数值时，还需要考虑不同的通信运营商。而在通信设备工作，需要调用功率设定参数值时，也需要首先分析通信设备的通信运营商，调用与通信运营商对应的功率设定参数值。
这里需要说明的是，通信设备的通信运营商与通信设备所接入的当地运营商是不同的概念。例如，某用户的手机使用中国移动的SIM卡，该手机的通信运营商为中国移动；在用户在中国国内时，手机接入中国移动的通信网络，手机接入的当地运营商以及手机的通信运营商均为中国移动；而当该用户旅行到法国时，手机通过中国移动的国际漫游服务接入法国本地的通信运营商(例如，O2)，手机接入的当地运营商就为O2，而手机的通信运营商为中国移动。
在本申请一实施例中，首先创建功控参数数据库，在功控参数数据库中预存不同通信运营商、不同应用场景、不同地区/国家、不同通信制式、不同通信频段所对应的功率设定参数值。
例如，针对某采用蜂窝移动通信技术实现通话的手机，创建功控参数数据库并在功控参数数据库中预存功率设定参数值的设定，功控参数数据库中包含下述功率设定参数值的设定：
1.通信运营商为中国移动；使用手机听筒接听通话，WiFi以及蓝牙均关闭；位于中国大陆境内并且驻留在中国移动的网络上；采用4G通信制式；通信频段为Band 34；对应的功率回退值为1dB(正值表示基于终端最大发射功率回退1dB)；
2.通信运营商为O2；使用手机听筒接听通话，WiFi以及蓝牙均关闭；位于法国境内并且驻留在O2的网络上；采用4G LTE通信制式；通信频段为Band 20；对应的功率回退值为1.5dB(正值表示基于终端最大发射功率回退1.5dB)；
3.测试用SIM或USIM卡(MCC-MNC＝001-01，MCC移动设备国家码，MNC移动设备网络代码)；使用手机听筒接听通话，WiFi打开，驻留于非运营商的实验网络或连接测试仪表(例如网络MCC-MNC＝001-01，不属于任何一个实体运营商)；采用WCDMA通信制式；通信频段为Band 8；目标发货地为中国，对应的功率回退值为2.5dB(正值表示基于终端最大发射功率回退2.5dB)。默认值配置会参照产品发货地强制认证要求，例如中国的国家无线电管理委员会(SRRC,State Radio Regulatory Commission of the People’s Republic of China，现国家无线电监测中心)强制核准要求或者美国联邦通信委员会(Federal Communications Commission,FCC)认证要求等。
图1所示为根据本申请一实施例的功率设定参数值配置方法流程图。在通信设备工作时，通信设备执行如图1所示的下述流程以配置射频器件的输出功率：
步骤111，获取通信设备当前的应用场景所对应的应用场景判定结果；
步骤112，确认通信设备当前的归属运营商信息；
步骤113，确认通信设备当前的驻网信息；
步骤130，基于应用场景判定结果、归属运营商信息以及驻网信息，在功控参数数据库中进行匹配检索，以获取对应应用场景判定结果、归属运营商信息以及驻网信息的功率设定参数值；
步骤140，根据功率设定参数值配置射频模块的输出功率。
具体的，在步骤130的一种实现方式中，根据归属运营商信息确定通信设备的通信运营商；根据驻网信息确定通信设备当前的通信制式、通信频段以及通信设备当前接入的当地运营商；根据通信设备当前接入的当地运营商确定通信设备当前所处的地区/国家；根据通信设备的应用场景判定结果、通信设备的通信运营商、通信设备当前的通信制式、通信设备当前的通信频段以及通信设备当前所处的地区/国家检索匹配的功率设定参数值。
根据图1所示实施例的方法，可以根据通信设备当前的具体状况确认匹配的功率设定参数值以配置射频模块；相较于现有技术的方法，根据图1所示实施例的方法，可以在确保通信设备满足SAR值标准的前提下，实现最大的发射功率，从而大大提高通信设备的工作性能。
进一步的，在实际应用场景中，功控参数数据库可以保存在通信设备上，也可以保存在云端服务器中。考虑到在大多数应用场景中，只有在配置好射频器件后，通信设备才能实现对外通信并访问云端服务器，因此，在本申请一实施例中，为了确保顺利的获取功率设定参数值，功控参数数据库保存在本地的通信设备中。具体的，在步骤130的一种实现方式中，在本地设备的功控参数数据库中进行匹配检索。
进一步的，考虑到在创建功控参数数据库、预存功率设定参数值时，有可能并未考虑到所有的功率设定参数值对应状况，例如，没有将地区A对应的功率设定参数值考虑在内。因此，在通信设备在本地的功控参数数据库中进行匹配检索，就有可能出现本地设备的功控参数数据库中不存在与应用场景判定结果、归属运营商信息以及驻网信息匹配的功率设定参数值的情况。例如，用户旅游到达地区A，但是在手机内置的功控参数数据库中，并 未预存地区A对应的功率设定参数值。
针对上述情况，在步骤130的一种实现方式中：
首先在本地设备的功控参数数据库中进行匹配检索；
当本地设备的功控参数数据库中不存在与应用场景判定结果、归属运营商信息以及驻网信息匹配的功率设定参数值时；
将应用场景判定结果、归属运营商信息以及驻网信息上传到云端服务器，以从云端服务器获取对应应用场景判定结果、归属运营商信息以及驻网信息的功率设定参数值。
例如，在一应用场景中，在用户A的手机中创建功控参数数据库、首次预存功率设定参数值时，没有将地区A对应的功率设定参数值考虑在内。当用户旅游到达地区A时，由于在手机内置的功控参数数据库中，并未预存地区A对应的功率设定参数值。因此，手机在功控参数数据库进行匹配检索后，无法获取可用的功率设定参数值；此时手机向云端服务器发送当前的应用场景判定结果、归属运营商信息以及驻网信息，由云端服务器进行匹配检索以获取对应应用场景判定结果、归属运营商信息以及驻网信息的功率设定参数值。最终由云端服务器将检索到的功率设定参数值发送给手机。
进一步的，在步骤130的一种实现方式中，当本地设备的功控参数数据库中不存在与应用场景判定结果、归属运营商信息以及驻网信息匹配的功率设定参数值时，从云端服务器下载功率设定参数值的补充信息，以扩充本地设备的功控参数数据库。在扩充后的功控参数数据库中进行匹配检索，以获取对应应用场景判定结果、归属运营商信息以及驻网信息的功率设定参数值。
例如，在一应用场景中，在用户A的手机中创建功控参数数据库、首次预存功率设定参数值时，没有将地区A对应的功率设定参数值考虑在内。当用户旅游到达地区A时，由于在手机内置的功控参数数据库中，并未预存地区A对应的功率设定参数值。因此，手机在功控参数数据库进行匹配检索后，无法获取可用的功率设定参数值；此时手机向云端服务器上报“地区A对应的功率设定参数值”缺失，从云端服务器处下载“地区A对应的功率设定参数值”以扩充手机内置的功控参数数据库。之后，手机在扩充后的功控参数数据库中进行匹配检索，以获取可用的功率设定参数值。
进一步的，在步骤130的一种实现方式中，针对某一通信方式(例如，蜂窝移动网络通信)，当本地设备的功控参数数据库中不存在与应用场景判定结果、归属运营商信息以及驻网信息匹配的功率设定参数值时，通过其他通信方式(例如，无线WiFi或者蓝牙)与云端服务器进行数据交互，以获取对应应用场景判定结果、归属运营商信息以及驻网信息的功率设定参数值。或者，使用预设的最小射频输出功率值配置射频器件的输出功率，基于最小射频输出功率与与云端服务器进行数据交互，以获取对应应用场景判定结果、归属运营商信息以及驻网信息的功率设定参数值，在获取到功率设定参数值后重新配置射频器件的输出功率。
进一步的，在20世纪90年代，对于一个技术的改进可以很明显地区分是硬件上的改进(例如，对二极管、晶体管、开关等电路结构的改进)还是软件上的改进(对于方法流程的改进)。然而，随着技术的发展，当今的很多方法流程的改进已经可以视为硬件电路结构的直接改进。设计人员几乎都通过将改进的方法流程编程到硬件电路中来得到相应的硬件电路结构。因此，不能说一个方法流程的改进就不能用硬件实体模块来实现。例 如，可编程逻辑器件(Programmable Logic Device,PLD)(例如现场可编程门阵列(Field Programmable Gate Array，FPGA))就是这样一种集成电路，其逻辑功能由访问方对器件编程来确定。由设计人员自行编程来把一个数字装置“集成”在一片PLD上，而不需要请芯片制造厂商来设计和制作专用的集成电路芯片。而且，如今，取代手工地制作集成电路芯片，这种编程也多半改用“逻辑编译器(logic compiler)”软件来实现，它与程序开发撰写时所用的软件编译器相类似，而要编译之前的原始代码也得用特定的编程语言来撰写，此称之为硬件描述语言(Hardware Description Language，HDL)，而HDL也并非仅有一种，而是有许多种，如ABEL(Advanced Boolean Expression Language)、AHDL(Altera Hardware Description Language)、Confluence、CUPL(Cornell University Programming Language)、HDCal、JHDL(Java Hardware Description Language)、Lava、Lola、MyHDL、PALASM、RHDL(Ruby Hardware Description Language)等，目前最普遍使用的是VHDL(Very-High-Speed Integrated Circuit Hardware Description Language)与Verilog。本领域技术人员也应该清楚，只需要将方法流程用上述几种硬件描述语言稍作逻辑编程并编程到集成电路中，就可以很容易得到实现该逻辑方法流程的硬件电路。
因此，根据本申请的方法，本申请还提出了一种射频输出功率配置装置。图2所示为根据本申请一实施例的射频输出功率配置装置的结构示意图。如图2所示，装置包括：
应用场景判定模块210，其用于获取通信设备当前的应用场景所对应的应用场景判定结果；
运营商信息获取模块220，其用于确认通信设备当前的归属运营商信息；
驻网信息获取模块230，其用于确认通信设备当前的驻网信息；

进一步的，射频输出功率配置装置还包括用于保存功控参数数据库的存储器260；
功率设定参数值获取模块240用于在存储器260保存的功控参数数据库中进行匹配检索。
进一步的，在一可行的应用方案中，功率设定参数值获取模块240还用于：
当存储器保存的功控参数数据库中不存在与应用场景判定结果、归属运营商信息以及当前驻网信息匹配的功率设定参数值时，将应用场景判定结果、归属运营商信息以及当前驻网信息上传到云端服务器，以从云端服务器获取对应应用场景判定结果、归属运营商信息以及驻网信息的功率设定参数值。
进一步的，在一可行的应用方案中，功率设定参数值获取模块240还用于：

在扩充后的功控参数数据库中进行匹配检索，以获取对应应用场景判定结果、归属运营商信息以及驻网信息的功率设定参数值。
在本申请实施例的描述中，为了描述的方便，描述装置时以功能分为各种模块分别描 述，各个模块的划分仅仅是一种逻辑功能的划分，在实施本申请实施例时可以把各模块的功能在同一个或多个软件和/或硬件中实现。
