Description

一种发射功率的调整方法及装置 技术领域
本发明涉及移动终端技术领域，尤其涉及一种发射功率的调整方法及装置。
背景技术
随着无线网络的发展，移动终端的应用越来越广泛，移动终端的发射源越来越多，例如有些移动终端中的发射源包括主卡Modem(调制解调器)、副卡Modem等，使得移动终端对人体的辐射越来越难以控制。目前以SAR(Specific Absorption Rate，电磁波吸收比值)衡量辐射对人体的影响，SAR代表单位质量的人体组织所吸收或消耗的电磁功率，SAR越低，辐射被人体吸收的量越少，为了控制移动终端对人体的辐射，规定移动终端产生的辐射不能超过SAR标准值。
通常，移动终端的通信质量越高，所需发射功率越大，同时产生的辐射就会越大，目前为了使移动终端中各发射源同时工作时产生的辐射不超过SAR标准值，一般会在移动终端生产时限制移动终端中各发射源的最大发射功率。
当具有多个发射源的移动终端处于信号较弱的场景中时，如果该移动终端的所有的发射源都在工作，各发射源的实际发射功率均小于生产该移动终端时为各发射源设置的各自的最大发射功率，才能保证该移动终端产生的辐射不会超过SAR值标准。而如果该移动终端只有少数的发射源在工作，例如只有一个发射源在工作时，该发射源需要较大的发射功率以保证在弱信号下的通信质量，由于一个发射源产生的辐射远低于SAR标准值，所以此时移动终端的通信质量还有提升空间，但是受限于移动终端生产时对该发射源的发射功率的限制，该发射源的实际发射功率只能维持在一个较低的区间，导致移动终端的通信质量低。

值得说明的是，图1仅为一种发射功率的调整系统的示例性示意图，本发明实施例提供的发射功率的调整方法不仅仅适用于图1所示的发射功率的调整系统。
结合图1，本发明实施例提供一种发射功率的调整方法，该方法应用于移动终端中，移动终端包括至少两个发射源，该方法的执行主体为图1中的SAR值处理模块，如图2所示，该方法包括：
201、获取当前状态信息组合，当前状态信息组合包括至少两个发射源中 每个发射源的当前状态。
结合图1所示的发射功率的调整系统，WIFI模块、主卡Modem和副卡Modem会向移动终端中的SAR值处理模块上报的各自的当前状态，以使得SAR值处理模块通过WIFI模块、主卡Modem和副卡Modem各自的当前状态组成的当前状态信息组合调整每个发射源的最大发射功率。
值得说明的是，每当发射源的状态发生变化时，状态发生变化的发射源都会向SAR值处理模块上报变化后的状态，从而使SAR值处理模块可以获取每个发射源的当前状态。例如，WIFI模块的状态从第一种状态变化到第二种状态，则WIFI模块需将第二种状态上报给SAR值处理模块，以便于SAR值处理模块在发射源的状态发生变化时，对每个发射源的最大发射功率进行调整。
202、获取当前状态信息组合下至少两个发射源中每个发射源的限制功率，至少两个发射源中每个发射源的限制功率为在移动终端产生的辐射不超过SAR标准值的前提下，至少两个发射源中每个发射源在当前状态信息组合下分别被允许的发射功率的最大值。
203、将至少两个发射源中每个发射源的最大发射功率分别调整为当前状态信息组合下至少两个发射源中每个发射源各自的限制功率。
每个发射源的状态不同，所需的最大发射功率也就不同，且需考虑整个移动终端产生的辐射，所以需要结合每个发射源的当前状态以及每个发射源的当前状态组成的状态信息组合来确定每个发射源的最大发射功率。
当SAR值处理模块将每个发射源的最大发射功率分别调整为当前状态信息组合下每个发射源各自的限制功率后，每个发射源的实际发射功率都可以达到当前各自被允许的发射功率的最大值，使在移动终端产生的辐射不超过SAR标准值的情况下，移动终端中各发射源的通信质量得到最大程度的保障。
本发明实施例提供的发射功率的调整方法，首先获取当前状态信息组合，当前状态信息组合包括至少两个发射源中每个发射源的当前状态，然后获取当前状态信息组合下至少两个发射源中每个发射源的限制功率，每个发射源的限制功率为在移动终端产生的辐射不超过SAR标准值的前提下，至少两个发射源中每个发射源被允许的发射功率的最大值，从而将至少两个发射源中 每个发射源的最大发射功率分别调整为当前状态信息组合下至少两个发射源中每个发射源各自的限制功率。与现有技术中具有多个发射源的移动终端在信号较弱的场景中，如果只有少数的发射源正在工作，即使移动终端产生的辐射远低于SAR标准值，少数工作中的发射源的发射功率仍只能维持在一个较低的区间，而导致移动终端的通信质量低相比，本发明实施例在设置各发射源的最大发射功率时，会结合各发射源的当前状态，根据当前状态信息组合，将每个发射源的最大发射功率分别调整为使得移动终端产生的辐射不超过SAR标准值时，每个发射源各自被允许的发射功率的最大值，使得各发射源的当前状态与调整后的各自的最大发射功率相适应，在移动终端产生的辐射不超过SAR标准值的情况下，最大化的保障了移动终端的通信质量，所以相比于现有技术，本发明实施例可以在移动终端产生的辐射不超过SAR标准值的前提下，当移动终端的通信质量还有提升空间时，提高移动终端的通信质量。
结合上述说明，本发明实施例还提供一种发射功率的调整方法，本实施例中具体描述了如何调整各发射源的最大发射功率，以及在调整各发射源的最大发射功率之前，确定每种状态信息组合下至少两个发射源中每个发射源各自的最大发射功率的方法，如图3所示，该方法包括：
301、将至少两个发射源中每个发射源的各个状态进行组合，得到至少两个状态信息组合，状态信息组合中包括至少两个发射源中每个发射源的一个状态。
值得说明的是，移动终端中的发射源包括WIFI模块、主卡Modem和副卡Modem。
其中，WIFI模块的状态为：关闭状态或WIFI连接状态或WIFI热点状态。关闭状态是指移动终端未开启WIFI，WIFI连接状态是指移动终端通过WIFI接入网络，WIFI热点状态是指移动终端作为WIFI热点为其他设备提供上网服务。
主卡Modem的状态为：主卡非工作状态或不同制式不同频段下的主卡工作状态。
主卡Modem是指双卡双待移动终端中的主卡对应的Modem，主卡的制 式包括2G(2-Generation wireless telephone technology，第二代手机通信技术规格)、3G(3rd-Generation，第三代移动通信技术)、4G(the 4th Generation mobile communication technology，第四代移动通信技术)，每个制式包括多个频段，例如，4G支持LTE(Long Term Evolution，长期演进)的Band(频段)1/Band3/Band7/Band38/Band39/Band40/Band41等。不同的制式采用的射频调制技术不同，且不同频段的发射频率也不同，使得主卡工作在不同制式不同频段下产生的辐射均不同。
主卡非工作状态是指主卡处于休眠待机状态，只会接收网络寻呼信息，不需要上行发射，基本不会产生辐射。主卡工作状态是指移动终端的主卡当前在进行通信，主卡在进行业务时所使用的制式或频段可能不同，所以产生的辐射也不同，例如主卡在进行呼叫业务时，可能使用3G的Band1，也可能使用2G的GSM(Global System for Mobile Communication，全球移动通信系统)1800。
副卡Modem的状态为：不同制式不同频段下的副卡工作状态或副卡非工作状态。副卡Modem是指双卡双待移动终端中副卡对应的Modem，在目前的双卡双待手机中，副卡Modem的功能比较弱，副卡的制式一般只支持2G，2G包括多个不同的频段，副卡工作在2G的不同频段下产生的辐射不同。
副卡非工作状态是指副卡处于休眠待机状态，只会接收网络寻呼信息，不需要上行发射，基本不会产生辐射。副卡工作状态是指移动终端的副卡当前在进行通信，副卡在进行业务时所处的制式或频段可能不同，所以产生的辐射也不同。
进一步值得说明的是，状态信息组合包括WIFI模块的一个状态、主卡Modem的一个状态、副卡Modem的一个状态。例如，一个状态信息组合为：WIFI关闭状态、4G的LTE Band1下的主卡工作状态，2G的GSM1800下的副卡工作状态组成的状态信息组合。
302、在每种状态信息组合下调整至少两个发射源中每个发射源的发射功率，使得在移动终端产生的辐射不超过SAR标准值的前提下，至少两个发射源中每个发射源的发射功率在每种状态信息组合下分别达到被允许的发射功率的最大值。
值得说明的是，一般通过测量移动终端中各发射源对某一位置点产生的辐射，例如在用户使用移动终端接电话时，各发射源对人脑产生的辐射来确定移动终端产生的辐射是否超过SAR标准值，在确定一种状态信息组合后，对各发射源的发射功率进行调整，使得各发射源对该位置点产生的辐射的叠加不超过SAR标准值，且在移动终端对该位置点的辐射不超过SAR标准值的情况下，移动终端的通信质量达到最好。
进一步值得说明的是，发射源在不同状态下所需的发射功率不同，例如，如果WIFI模块处于关闭状态，则WIFI模块不会产生辐射，而主卡和副卡都在工作，则可以适当增大主卡Modem和副卡Modem的最大发射功率，保证主卡Modem和副卡Modem产生的辐射不超过SAR标准即可；而如果WIFI处于关闭状态，副卡处于副卡非工作状态，主卡在进行通话业务，则WIFI模块和副卡Modem都不会产生辐射，发射功率几乎为0，相当于移动终端中只有一个发射源在工作，则可以增大主卡Modem的最大发射功率，保证主卡Modem产生的辐射不超过SAR标准即可，这样既会使主卡的通信质量达到最好，又可以保证移动终端产生的辐射不超过SAR标准。
结合上述描述，可以理解的是，如果移动终端中只有一个发射源，相当于上述描述中的移动终端只有一个发射源在工作的情况，此时只需保证该发射源产生的辐射不超过SAR标准值即可。
303、将每种状态信息组合下调整后的至少两个发射源中每个发射源的发射功率确定为至少两个发射源中每个发射源各自的限制功率。
可以理解的是，当确定每种状态信息组合下每个发射源的限制功率之后，SAR值处理模块会将确定的每种状态信息组合下每个发射源的限制功率存储在数据库中。
值得说明的是，上述步骤301至303为确定并存储移动终端中每个发射源的限制功率的过程，在将移动终端的每种状态信息组合下每个发射源的限制功率均进行存储之后，即可在移动终端实际使用时，根据移动终端中各发射源的当前状态实时对每个发射源的最大发射功率进行调整。
304、获取WIFI模块、主卡Modem和副卡Modem各自的当前状态。
结合图1所示的发射功率的调整系统，每个发射源的状态发生改变时都 会向SAR值处理模块上报改变后的状态，使得SAR值处理模块可以获取到WIFI模块、主卡Modem和副卡Modem各自的当前状态。
305、通过WIFI模块、主卡Modem和副卡Modem各自的当前状态，确定当前状态信息组合。
值得说明的是，当前状态信息组合由WIFI模块、主卡Modem、副卡Modem各自的当前状态组成，当前状态信息组合为数据库中存储的状态信息组合中的一种，通过当前状态信息组合可以从数据库中查找到当前状态信息组合下每个发射源的限制功率。
306、获取当前状态信息组合下WIFI模块、主卡Modem和副卡Modem各自的限制功率。
307、将WIFI模块、主卡Modem和副卡Modem的最大发射功率分别调整为当前状态信息组合下WIFI模块、主卡Modem和副卡Modem各自的限制功率。
本发明实施例提供的发射功率的调整方法，首先将至少两个发射源中每个发射源的各个状态进行组合，得到至少两个状态信息组合，然后在每种状态信息组合下调整至少两个发射源中每个发射源的发射功率，使得在移动终端产生的辐射不超过SAR标准值的前提下，至少两个发射源中每个发射源的发射功率在每种状态信息组合下分别达到被允许的发射功率的最大值，将每种状态信息组合下调整后的每个发射源的发射功率确定为每个发射源各自的限制功率，之后在移动终端正常工作时获取WIFI模块、主卡Modem、副卡Modem各自的当前状态，通过WIFI模块、主卡Modem、副卡Modem各自的当前状态，确定当前状态信息组合，获取当前状态信息组合下至少两个发射源中每个发射源的限制功率，从而将每个发射源的最大发射功率分别调整为当前状态信息组合下每个发射源各自的限制功率。事先对每种状态信息组合下每个发射源的发射功率进行调整，并将确定的每种状态信息组合下每个发射源的限制功率存储在数据库中，在调整各发射源的最大发射功率时，即可直接从数据库中获取当前状态信息组合对应的每个发射源的限制功率，使得调整最大发射功率比较方便快捷，且将当前状态信息组合下的每个发射源的最大发射功率调整为移动终端产生的辐射不超过SAR标准值时，每个发射 源各自被允许的发射功率的最大值，可以使移动终端的通信质量得到保障。
结合图2所示的方法流程，本发明实施例还提供一种发射功率的调整方法，在本实施例中，移动终端中还包括SIM卡模块，如图4所示，该方法包括：
401、通过SIM卡模块获取主卡的MCC。
其中，MCC用于代表移动终端中的主卡所属国家，每个国家要求的SAR值不同，所以在为各发射源调整最大发射功率时还需参考移动终端中的主卡所属国家的SAR标准值。
402、获取当前状态信息组合，当前状态信息组合包括至少两个发射源中每个发射源的当前状态。
403、获取同时与MCC和当前状态信息组合对应的至少两个发射源中每个发射源的限制功率。
可以理解的是，在本实施例中，数据库中存储了不同MCC下的每种状态信息组合对应的每个发射源的限制功率。
404、将至少两个发射源中每个发射源的最大发射功率分别调整为同时与MCC和当前状态信息组合对应的每个发射源各自的限制功率。
本发明实施例提供的发射功率的调整方法，通过SIM卡模块获取主卡的MCC，再获取当前状态信息组合，然后获取同时与MCC和当前状态信息组合对应的至少两个发射源中每个发射源的限制功率，从而将至少两个发射源中每个发射源的最大发射功率分别调整为同时与MCC和当前状态信息组合对应的每个发射源各自的限制功率。由于不同国家规定的SAR标准值不同，所以本发明实施例会根据主卡的MCC确定主卡所属国家，在移动终端产生的功率不超过主卡所属国家规定的SAR标准值的情况下，将每个发射源各自的最大发射功率调整为当前状态组合下被允许的发射功率的最大值，保障了移动终端的通信质量，且即使将移动终端中SAR值标准高的国家的主卡更换为SAR值标准低的国家的主卡，本发明实施例也会根据当前主卡所属国家调整移动终端中各发射源的最大发射功率，不会使移动终端产生的辐射超过当前主卡所属国家的SAR标准值。
结合图2至图4所示的方法流程，本发明实施例还提供一种发射功率的 调整装置，该装置应用于移动终端中，移动终端中包括至少两个发射源，如图5所示，该装置包括：获取单元51、调整单元52。
获取单元51，用于获取当前状态信息组合，当前状态信息组合包括至少两个发射源中每个发射源的当前状态；获取当前状态信息组合下至少两个发射源中每个发射源的限制功率，至少两个发射源中每个发射源的限制功率为在移动终端产生的辐射不超过电磁波吸收比值SAR标准值的前提下，至少两个发射源中每个发射源在当前状态信息组合下分别被允许的发射功率的最大值。
调整单元52，用于将所述至少两个发射源中每个发射源的最大发射功率分别调整为获取单元51获取的所述当前状态信息组合下所述至少两个发射源中每个发射源各自的限制功率。

进一步的，结合图5，本发明实施例还提供一种发射功率的调整装置，如图6所示，该装置还包括：组合单元53，确定单元54。
组合单元53，用于将至少两个发射源中每个发射源的各个状态进行组合，得到至少两个状态信息组合，状态信息组合中包括每个发射源的一个状态。

调整单元52，还用于在每种状态信息组合下调整至少两个发射源中每个发射源的发射功率，使得在移动终端产生的辐射不超过SAR标准值的前提下，至少两个发射源中每个发射源的发射功率在每种状态信息组合下分别达到被允许的发射功率的最大值。
确定单元54，用于将每种状态信息组合下调整单元52调整后的至少两个发射源中每个发射源的发射功率确定为至少两个发射源中每个发射源各自的限制功率。
进一步的，获取单元51，还用于获取WIFI模块、主卡Modem和副卡Modem各自的当前状态。
确定单元54，还用于通过获取单元51获取的WIFI模块、主卡Modem和副卡Modem各自的当前状态，确定当前状态信息组合。
可选的，获取单元51，还用于通过SIM卡模块获取主卡的移动信号国家码MCC。
获取单元51，还用于获取同时与MCC和当前状态信息组合对应的至少两个发射源中每个发射源的限制功率。
调整单元52，还用于将至少两个发射源中每个发射源的最大发射功率分别调整为获取单元51获取的同时与MCC和当前状态信息组合对应的每个发射源各自的限制功率。
本发明实施例提供的发射功率的调整装置，获取单元通过SIM卡模块获取主卡的MCC，获取至少两个发射源中每个发射源的当前状态，再通过至少两个发射源中每个发射源的当前状态得到当前状态信息组合，然后获取同时与MCC和当前状态信息组合对应的至少两个发射源中每个发射源的限制功率，进而调整单元将每个发射源的最大发射功率分别调整为同时与MCC和当前状态信息组合对应的每个发射源各自的限制功率。由于不同国家规定的SAR标准值不同，所以本发明会根据主卡的MCC确定主卡所属国家，在移动终端产生的功率不超过主卡所属国家规定的SAR标准值的情况下，将每个发射源各自的最大发射功率调整为当前状态组合下被允许的发射功率的最大值，保障了移动终端的通信质量，且即使将移动终端中SAR值标准高的国家的主卡更换为SAR值标准低的国家的主卡，本发明也会根据当前主卡所属国家调整移动终端中各发射源的最大发射功率，不会使移动终端产生的辐射超过当前主卡所属国家的SAR标准值。

存储器71，还用于存储处理器73确定的调整后的每种状态信息组合下至少两个发射源中每个发射源72各自的限制功率。
值得说明的是，发射源72包括无线保真WIFI模块、主卡Modem和副卡Modem。
