下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。应当理解，此处所描述的具体实施例仅仅用于解释本申请，并不用于限定本申请。基于本申请中的实施例，本领域普通技术人员在没有作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。
本申请实施例提供了一种消除对GPS信号干扰的方法、装置、移动终端及存储介质。
请参阅图1，图1为本申请实施例方案涉及的降低对GPS信号干扰的装置的硬件结构示意图。
所述降低对GPS信号干扰的装置在硬件结构上可以包括处理器1001、通信模块1002以及存储器1003等部件。本领域技术人员可以理解，图1中示出的降低对GPS信号干扰的装置结构并不构成对降低对GPS信号干扰的装置的限定，可以包括比图示更多或更少的部件，或者组合某些部件，或者不同的部件布置。其中，所述处理器1001分别与所述存储器1003以及所述通信模块1002连接，所述存储器1003上存储有降低对GPS信号干扰的程序，所述降低对GPS信号干扰的程序同时被处理器1001执行，所述降低对GPS信号干扰的程序执行时实现下述方法实施例的步骤。
处理器1001，是降低对GPS信号干扰的装置的控制中心，利用各种接口和线路连接整个降低对GPS信号干扰的装置的各个部分，通过运行或执行存储在存储器1003内的软件程序和/或模块，以及调用存储在存储器1003内的数据，执行降低对GPS信号干扰的装置的各种功能和处理数据，近而对降低对GPS信号干扰的装置进行整体监控。处理器1001可包括一个或多个处理单元；在一实施方式中，处理器1001可集成应用处理器和调制解调处理器，其中，应用处理器主要处理操作系统、用户界面和应用程序等，调制解调处理器主要处理无线通信。可以理解的是，上述调制解调处理器也可以不集成到处理器1001中。

尽管图1未示出，但上述降低对GPS信号干扰的装置还可以包括电路控制模块，用于与电源连接，保证其他部件的正常工作。
根据上述硬件结构，提出本申请方法各个实施例。
参照图2，为本申请消除对GPS信号干扰的方法第一实施例的流程示意图，该方法包括以下步骤：
步骤S100，在检测到移动终端开启GPS时，判断所述移动终端是否接收网络信号；
在本申请中，本实施例中，网络信号可以是蜂窝网络信号，比如2G网络信号、3G网络信号、4G网络信号以及5G网络信号等。本实施例以网络信号为LTE网络信号为例进行说明。用户在携带移动终端，比如携带手机或智能手表进行跑步时，可能会在使用移动终端GPS定位动能的同时会用移动终端来听音乐等。在检测到移动终端开启GPS时，判断移动终端是否接收LTE网络信号，以判断用户在使用移动终端GPS定位功能的同时是否在使用LTE网络听音乐等。
步骤S200，若所述移动终端接收网络信号，则获取网络信号当前运行的网络频点；
若移动终端接收网络信号，即，用户在使用移动终端GPS定位功能的同时还在听音乐等，那么，LTE网络可能会对GPS信号造成干扰，这种情况下，可先获取网络信号当前运行的网络频点。
步骤S300，判断网络信号当前运行的网络频点是否对GPS信号造成干扰；
在获取网络信号当前运行的网络频点后，继续判断网络信号当前运行的网络频点是否对GPS信号造成干扰，比如，网路信号当前运行的网络频点可对GPS信号造成倍频干扰或互调干扰，会影响GPS的定位功能。判断网络信号当前运行的网络频点是否对GPS信号造成干扰，可通过检测GPS的信号强度判断，若GPS的信号强度变弱程度加大或不稳定，则判定网络信号当前运行的网络频点对GPS造成了干扰。
步骤S400，若网络信号当前运行的网络频点对GPS信号造成干扰，则将网络信号切换至预设网络频点运行，所述预设网络频点为对GPS信号不造成干扰的网络频点。
若网络信号当前运行的网络频点对GPS信号造成干扰，则可将网络信号切换至预设网络频点运行，该预设网络频点为对GPS信号不造成干扰的频点，需要说明的是，预设网络频点可以是对GPS信号不会造成倍频干扰及互调干扰的网络频点。在网络信号当前运行的网络频点对GPS信号造成干扰的情况下，将网络信号切换至对GPS信号不造成干扰的预设网络频点运行，从而使得网络信号当前运行的网络频点避开对GPS信号造成干扰的频点，以使移动终端在网络信号与GPS信号同时运行的情况下，网络信号不会对GPS信号造成干扰，保证GPS定位功能的正常使用。
本实施例消除对GPS信号干扰的方法中，通过在检测到移动终端开启GPS时，判断所述移动终端是否接收网络信号，在所述移动终端接收网络信号的情况下，获取网络信号当前运行的网络频点，并判断网络信号当前运行的网络频点是否对GPS信号造成干扰，若网络信号当前运行的网络频点对GPS信号造成干扰，则将网络信号切换至对GPS信号不造成干扰的预设网络频点运行，从而使得网络信号当前运行的网络频点避开对GPS信号造成干扰的频点，以使移动终端在网络信号与GPS信号同时运行的情况下，网络信号不会对GPS信号造成干扰，即，消除网络信号对GPS造成干扰的风险，保证GPS定位功能的正常使用。
同时，本实施例消除对GPS信号干扰的方法中，在网络信号当前运行的网络频点是否对GPS信号造成干扰的情况下，只是对网络信号的网络频点进行切换，并不用降低网络信号的发射功率，在消除对GPS造成干扰的情况下，还能同时保证移动终端自身通话的质量不受影响。并且，该方法也不需在GPS电路中增加陷波器来滤除干扰信号，降低了成本投入。
可以理解地，在检测到移动终端开启GPS时，移动终端没有接收网络信号的情况下，比如，用户在使用移动终端GPS定位功能时，并没有同时听音乐等，此时，没有网络信号对GPS信号造成干扰，则不必进行后续获取网络信号当前运行的网络频点以及判断网络信号当前运行的网络频点是否对GPS信号造成干扰等步骤。
另外，需要说明的是，在步骤S300之后，还包括：
步骤S500，若网络信号当前运行的网络频点不对GPS信号造成干扰，则保持网络信号当前运行的网络频点不变。即，无需切换网络信号当前运行的网络频点，保持移动终端网络信号的正常运行。
进一步的，参照图3，为本申请消除对GPS信号干扰的方法第二实施例的流程示意图，基于上述第一实施例，步骤S300包括：
步骤S301，判断预设干扰频点集合中是否存在与网络信号当前运行的网络频点相同的频点；
步骤S400包括：
步骤S401，若预设干扰频点集合中存在与网络信号当前运行的网络频点相同的频点，则判定网络信号当前运行的网络频点对GPS信号造成干扰，将网络信号切换至预设网络频点运行。
具体地，在移动终端接收网络信号，获取网络信号当前运行的网络频点后，可判断预设干扰频点集合中是否存在与网络信号当前运行的网络频点相同的频点，其中，预设干扰频点集合即为预设的可能对GPS信号造成干扰的频点的集合，预设干扰频点集合可以是写入移动终端的寄存器中的对GPS信号造成倍频干扰及互调干扰的网络频点的集合。若预设干扰频点集合中存在与网络信号当前运行的网络频点相同的频点，则判定网络信号当前运行的网络频点对GPS信号造成干扰，将网络信号切换至预设网络频点运行。
本实施例将可能对GPS信号造成干扰的频点进行集合，形成预设干扰频点集合，使得网络信号当前运行的网络频点可以直接在预设干扰频点集合中快速查找，若查找出相同的频点，即，网络信号当前运行的网络频点与预设干扰频点集合重合，表明网络信号当前运行的网络频点会对GPS信号造成干扰，则将网络信号切换至对GPS信号不造成干扰的预设网络频点运行即可，快速方便。
进一步的，步骤S301包括：
步骤S3011，从寄存器中获取预设干扰频点集合；
如上所述，预设干扰频点集合可以是写入移动终端的寄存器中的对GPS信号造成倍频干扰及互调干扰的网络频点的集合，那么，在判断预设干扰频点集合中是否存在与网络信号当前运行的网络频点相同的频点时，可直接从寄存器中获取预设干扰频点集合。
进一步的，参照图4，为本申请消除对GPS信号干扰的方法第三实施例的流程示意图，基于上述第一实施例，所述移动终端具有第一网络发射通路和/或第二网络发射通路，所述第一网络发射通路的网络频率为第一网络频率f1，所述第二网络发射通路的网络频率为第二网络频率f2；
步骤S300包括：
步骤S302，判断f1的倍频、f2的倍频以及f1和f2的互调分量是否处于预设频率范围，所述预设频率范围为对GPS信号造成干扰的频率范围；
步骤S400包括：
步骤S402，若f1的倍频、f2的倍频以及f1和f2的互调分量处于预设频率范围，则判定网络信号当前运行的网络频点对GPS信号造成干扰，将网络信号切换至预设网络频点运行。
可以理解地，第一网络发射通路的第一网络频率f1或者第二网络发射通路的第二网络频率f2产生GPS频段的互调信号，又或者，第一网络发射通路的二阶谐波有可能会与第二网络发射通路产生GPS频段的互调信号，而该互调信号辐射到GPS天线，形成带内噪声，SAW Filter滤不掉，使得Noise
Floor升高，CN0下降，影响GPS接收信号。
本实施例中，可在获取第一网络发射通路的第一网络频率f1以及第二网络发射通路的第二网络频率f2后，判断f1的倍频、f2的倍频以及f1和f2的互调分量是否处于预设频率范围，该预设频率范围为对GPS信号造成干扰的频率范围，若f1的倍频、f2的倍频以及f1和f2的互调分量处于预设频率范围，则判定网络信号当前运行的网络频点对GPS信号造成干扰，将网络信号切换至预设网络频点运行。
在判定网络信号当前运行的网络频点对GPS信号造成干扰的情况下，可通过改变移动终端的其中一条网络发射通路的网络频率，即改变移动终端的第一网络发射通路的第一网络频率f1或改变移动终端的第二网络发射通路的第二网络频率f2，具体可使第一网络频率f1增加或减小，或使第二网络频率f2增加或减小，即可使f1的倍频、f2的倍频以及f1和f2的互调分量不处于预设频率范围内，以使移动终端在网络信号与GPS信号同时运行的情况下，网络信号不会对GPS信号造成干扰，即，消除网络信号对GPS造成干扰的风险，保证GPS定位功能的正常使用。通过判断f1的倍频、f2的倍频以及f1和f2的互调分量是否处于预设频率范围内的方式，可提高判定网络信号当前运行的网络频点对GPS信号造成干扰的准确性和全面性。
需要说明的是，通过判断f1的倍频、f2的倍频以及f1和f2的互调分量是否处于预设频率范围来判定网络信号当前运行的网络频点对GPS信号造成干扰，将网络信号切换至预设网络频点运行的步骤还可以在判断预设干扰频点集合中是否存在与网络信号当前运行的网络频点相同的频点的步骤之后执行，即步骤S302可以在步骤S200之后执行，还可以在步骤S301之后执行，具体地，在判断预设干扰频点集合中是否存在与网络信号当前运行的网络频点相同的频点后，若f1的倍频、f2的倍频以及f1和f2的互调分量处于预设频率范围，则判断第一网络发射通路的网络频点和第二网络发射通路的网络频点是否存在于预设干扰频点集合内，即判断预设干扰频点集合是否存在与第一网络发射通路的网络频点和第二网络发射通路的网络频点相同的频点，若不存在，则将第一网络发射通路的网络频点和第二网络发射通路的网络频点添加至寄存器的预设干扰频点集合内，提高预设干扰频点集合的全面性，进而在移动终端在网络信号与GPS信号同时运行的情况下，提高消除网络信号对GPS信号造成干扰风险的准确性、有效性和可靠性。
进一步的，步骤S303包括：
步骤S3031，判断f1的倍频，f2的倍频，f1和f2的二阶互调分量，以及f1和f2的三阶互调分量是否处于预设频率范围。
f1的倍频，f2的倍频，以及在f1和f2的互调分量中，f1和f2的二阶互调分量，以及f1和f2的三阶互调分量的功率是相对较大的，即，f1的倍频，f2的倍频，f1和f2的二阶互调分量f2-f1、f2+f1，其中，f2＞f1，以及f1和f2的三阶互调分量2f2-f1、2f1-f2可能在GPS频点附近，对GPS信号的干扰较大，那么，可主要判断f1的倍频，f2的倍频，f1和f2的二阶互调分量，以及f1和f2的三阶互调分量是否处于预设频率范围即可快速判断网络信号当前运行的网络频点对GPS信号是否造成干扰，快速方便。
进一步的，参照图5，为本申请消除对GPS信号干扰的方法第四实施例的流程示意图，基于上述第一实施例，在所述步骤S300之前，包括：
步骤S201，比对移动终端未接收网络信号时GPS信号的强度和接收网络信号时GPS信号的强度，得到比对结果；
步骤S300包括：
步骤S303，根据比对结果判断网络信号当前运行的网络频点是否对GPS信号造成干扰。
可以理解地，移动终端在网络信号与GPS信号同时运行的情况下，若网络信号对GPS信号造成干扰，GPS信号的信号强度会发生变化。本实施例在判断网络信号当前运行的网络频点是否对GPS信号造成干扰之前，先比对移动终端未接收网络信号时GPS信号的强度和接收网络信号时GPS信号的强度，得到比对结果，从而根据比对结果判断网络信号当前运行的网络频点是否对GPS信号造成干扰。
本实施例通过比对移动终端未接收网络信号时GPS信号的强度和接收网络信号时GPS信号的强度，可快速得出比对结果，从比对结果可得出GPS信号的强度在未接收网络信号和接收网络信号时的变化量，进而可直接根据比对结果来判断网络信号当前运行的网络频点是否对GPS信号造成干扰，快速方便。
进一步的，步骤S201包括：
步骤S2011，获取移动终端未接收网络信号时GPS信号的强度和接收网络信号时GPS信号的强度的差值；
步骤S303包括：
步骤S3031，判断差值是否在预设差值范围内；
步骤S400包括：
步骤S403，若差值在预设差值范围内，则判定网络信号当前运行的网络频点对GPS信号造成干扰，将网络信号切换至预设网络频点运行。
移动终端未接收网络信号时GPS信号的强度和接收网络信号时GPS信号的强度的比对结果可由两者信号强度的差值体现，通过获取移动终端未接收网络信号时GPS信号的强度和接收网络信号时GPS信号的强度的差值，并判断差值是否在预设差值范围内，该预设差值范围为预设的网络信号当前运行的网络频点会对GPS信号造成干扰的强度差值范围。本实施例中，移动终端未接收网络信号时GPS信号的强度和接收网络信号时GPS信号的强度的差值为大于2dBHz时，则该差值在预设差值范围，进而判定网络信号当前运行的网络频点对GPS信号造成干扰，将网络信号切换至预设网络频点运行。可以理解地，若移动终端未接收网络信号时和接收网络信号时两者之间的GPS信号强度变化不大，比如，小于2dBHz，则该差值不在预设差值范围内，则判定网络信号当前运行的网络频点不对GPS信号造成干扰，则不必切换网络信号的网络频点，网络信号继续以当前运行的网络频点运行。
需要说明的是，通过获取移动终端未接收网络信号时GPS信号的强度和接收网络信号时GPS信号的强度的差值，判断差值是否在预设差值范围内来判定网络信号当前运行的网络频点对GPS信号造成干扰，将网络信号切换至预设网络频点运行的步骤还可以在判断预设干扰频点集合中是否存在与网络信号当前运行的网络频点相同的频点的步骤之后执行，即步骤S201可以在步骤S200之后执行，还可以在步骤S301之后执行，具体地，在判断预设干扰频点集合中是否存在与网络信号当前运行的网络频点相同的频点后，若f1的倍频、f2的倍频以及f1和f2的互调分量不处于预设频率范围，则获取移动终端未接收网络信号时GPS信号的强度和接收网络信号时GPS信号的强度的差值，判断差值是否在预设差值范围内，若差值在预设差值范围内，则判定网络信号当前运行的网络频点对GPS信号造成干扰，判断此时网络信号当前运行的网络频点是否存在于预设干扰频点集合内，即判断预设干扰频点集合是否存在与网络信号当前运行的网络频点相同的频点，若不存在，则将网络信号当前运行的网络频点添加至寄存器的预设干扰频点集合内，提高预设干扰频点集合的全面性，进而在移动终端在网络信号与GPS信号同时运行的情况下，提高消除网络信号对GPS信号造成干扰风险的准确性、有效性和可靠性。
此外，为实现上述目的，本申请还提出一种移动终端，所述移动终端包括存储器、处理器和存储在所述存储器上并可在所述处理器上运行的计算机程序，所述计算机程序被所述处理器执行时实现如上所述的消除对GPS信号干扰的方法的步骤。本申请的移动终端可以是手机或智能手表等，本申请移动终端的具体实施例与上述消除对GPS信号干扰的方法各实施例基本相同，在此不作赘述。

此外，在本申请中涉及“第一”、“第二”、“第三”、“第四”等的描述仅用于描述目的，而不能理解为指示或暗示其相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”“第一”、“第二”、“第三”、“第四”的特征可以明示或者隐含地包括至少一个该特征。另外，各个实施例之间的技术方案可以相互结合，但是必须是以本领域普通技术人员能够实现为基础，当技术方案的结合出现相互矛盾或无法实现时应当认为这种技术方案的结合不存在，也不在本申请要求的保护范围之内。
上述本申请实施例序号仅仅为了描述，不代表实施例的优劣。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到上述实施例方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本申请的技术方案本质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在如上所述的一个存储介质(如ROM/RAM、磁碟、光盘)中，包括若干指令用以使得一台终端设备(可以是手机，计算机，服务器，终端，或者网络设备等)执行本申请各个实施例所述的方法。
