本公开涉及通信技术领域，尤其涉及一种干扰处理方法及移动终端。
随着通信技术的不断发展，用户对通信速率的要求越来越高。为了提高通信速率，在未来移动通信系统中，例如，第五代(5th Generation，5G)移动通信系统，一些移动终端支持双连接。例如，移动终端支持同时连接长期演进(Long Term Evolution，LTE)网络和5G网络，并可通过LTE网络和5G网络共同传输数据。
目前，移动终端通常还包括定位模块，例如，GPS(Global Positioning System，全球定位系统)模块。然而，在移动终端同时连接两个不同频段的网络发射信号的情况下，两个不同频率的发射信号易对定位模块产生较大干扰，影响定位模块的定位性能。

下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，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，都属于本公开保护的范围。
为了便于描述，以下对本公开实施例涉及的一些内容进行说明：
第五代(5th Generation，5G)：5G是继LTE之后的下一代移动通信技术，支持更高速率、更低使用和更大连接数。其中，5G提出了一系列的关键技术，例如，统一的空口技术架构，新型的多址接入技术，大规模天线技术，超密集组网技术，以及高频通信技术等。
非独立组网(Non-Stand Alone，NSA)架构：在NSA架构下，通过LTE 和5G双连接的机制，数据面通过LTE和5G通路传输以满足高速率需求，5G网络的控制面通过LTE通路传输，以保证上行的覆盖性能。此外，在此机制下还定义了一系列的频段组合，例如，LTE的B3/8/39/41和5G的n78，LTE的B3/8/29/41和5G的n79等。
独立组网(Stand Alone，SA)架构：在SA架构下，5G网络的控制面和数据面都通过5G通路传输。为了解决上行覆盖问题，引入了上行2*2多输入多输出(Multi In Multi Out，MIMO)机制，或者称为闭环空分多址(即Closed-loop Spatial Multiplexing)机制。通过引入上行两路同时发射，来提高终端的等效发射功率，达到提升上行覆盖的目的。
双频GPS：双频GPS越来越多的应用在移动终端上，支持两种频段，例如，L1和L5。由于在移动终端上应用双频GPS，移动终端在室外可达到车道级别的精确度，在城市场景中对多路径和反射信号具有更高的抵抗力，并且具有更高的抗干扰和抗干扰能力。此外，同时使用两个频段也可以减少其他来源的误差，例如，由电离层中的电子干扰引起的误差。
本公开实施例提供一种干扰处理方法，应用于移动终端。参见图1，图1是本公开实施例提供的干扰处理方法的流程图，如图1所示，包括以下步骤：
步骤101、在移动终端连接第一网络和第二网络的情况下，检测目标频率是否对所述移动终端的定位模块的第一工作频段产生干扰，其中，所述目标频率为所述第一网络的工作频率和所述第二网络的工作频率交调后得到的频率。
本实施例中，上述移动终端可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(personal digital assistant，PDA)或可穿戴式设备(Wearable Device)等。
上述第一网络和第二网络可以是任意两个不同的网络。例如，在NSA架构下，上述第一网络可以为5G网络，上述第二网络可以为LTE网络。
上述目标频率可以是上述第一网络的工作频率和第二网络的工作频率交调得到的频率。例如，第一网络的工作频率为f1，第二网络的工作频率为f2，则上述目标频率可以包括m*f1+n*f2和m*f1-n*f2中的至少一项，其中，m和n均为正整数。
上述定位模块可以是GPS模块、北斗卫星导航系统模块或伽利略定位系统模块等。上述定位模块的第一工作频段可以是定位模块当前工作的所有频段中的任意工作频段。例如，以上述定位模块为GPS模块为例，上述第一工作频段可以是L1或是L5等。
实际应用中，可以在移动终端同时连接第一网络和第二网络，且定位模块处于工作状态的情况下，检测第一网络的工作频率和第二网络的工作频率交调后得到的频率是否对定位模块的第一工作频段产生干扰。例如，检测第一网络的工作频率和第二网络的工作频率交调后得到的频率是否位于定位模块的第一工作频段内，或是检测第一网络的工作频率和第二网络的工作频率交调后得到的频率是否较为靠近定位模块的第一工作频段等。
步骤102、在所述目标频率对所述第一工作频段产生干扰的情况下，调整所述第一网络的发射时隙和所述第二网络的发射时隙的至少一者，以使第一重叠数量小于第二重叠数量，其中，所述第一重叠数量为调整后的所述第一网络的发射时隙和所述第二网络的发射时隙的重叠数量，所述第二重叠数量为调整前的所述第一网络的发射时隙和所述第二网络的发射时隙的重叠数量。
本实施例中，在第一网络的工作频率和第二网络的工作频率交调后得到的频率对所述第一工作频段产生干扰的情况下，可以调整第一网络的发射时隙和所述第二网络的发射时隙中的至少一项，以减少第一网络的发射时隙和第二网络的发射时隙的重叠数量。
例如，参见图2，在一个时分双工(Time Division Duplexing，TDD)周期内，在调整前的4G发射时隙和5G发射时隙重叠数量为4，在调整4G发射时隙之后，4G发射时隙和5G发射时隙的重叠数量减少为1。
又例如，参见图3，在一个TDD周期内，在调整之前4G发射时隙和5G发射时隙重叠数量为4，在调整5G发射时隙之后，4G发射时隙和5G发射时隙的重叠数量减少为0。
本公开实施例通过在所述第一网络的工作频率和所述第二网络的工作频率交调后得到的频率对所述第一工作频段产生干扰的情况下，调整所述第一网络的发射时隙和所述第二网络的发射时隙的至少一者，以减少第一网络的发射时隙和第二网络的发射时隙的重叠数量，进而可以减少通过第一网络和 第二网络同时发射信号的数量。这样可以减少第一网络的发射信号和第二网络的发射信号对定位模块接收信号的干扰，提高定位模块的定位性能。
参见图4，图4是本公开实施例提供的干扰处理方法的流程图。本公开实施例与上一实施例的区别主要在于对如何检测目标频率是否对所述移动终端的定位模块的第一工作频段产生干扰进行了进一步限定。本公开实施例中，所述检测目标频率是否对所述移动终端的定位模块的第一工作频段产生干扰，包括：检测所述目标频率是否位于所述第一工作频段内；所述在所述目标频率对所述第一工作频段产生干扰的情况下，调整所述第一网络的发射时隙和所述第二网络的发射时隙的至少一者，包括：在所述目标频率位于所述第一工作频段内的情况下，调整所述第一网络的发射时隙和所述第二网络的发射时隙的至少一者。
如图4所示，本公开实施例提供的干扰处理方法可以包括以下步骤：
步骤401、在移动终端连接第一网络和第二网络的情况下，检测目标频率是否位于所述移动终端的定位模块的第一工作频段内，其中，所述目标频率为所述第一网络的工作频率和所述第二网络的工作频率交调后得到的频率。
步骤402、在所述目标频率位于所述第一工作频段内的情况下，调整所述第一网络的发射时隙和所述第二网络的发射时隙的至少一者，以使第一重叠数量小于第二重叠数量，其中，所述第一重叠数量为调整后的所述第一网络的发射时隙和所述第二网络的发射时隙的重叠数量，所述第二重叠数量为调整前的所述第一网络的发射时隙和所述第二网络的发射时隙的重叠数量。
实际应用中，由于定位模块的接收信号能量相对较低，在第一网络的工作频率和第二网络的工作频率交调后得到的频率位于定位模块的工作频段内的情况下，第一网络的工作频率和第二网络的工作频率交调后得到的频率会对定位模块接收信号造成较大干扰。例如，参见图5，移动终端的5G射频模块的5G天线和4G射频模块的4G天线同时发射信号，其中，5G天线的发射频率为f1，4G天线的发射频率为f2，若f1-f2位于移动终端的GPS射频模块的GPS天线的接收频段内，则会对GPS模块造成较大的干扰。
因此，本实施例可以在第一网络的工作频率和第二网络的工作频率交调后得到的频率位于第一工作频段内的情况下，调整第一网络的发射时隙和第 二网络的发射时隙中的至少一项，以减少第一网络的发射时隙和第二网络的发射时隙的重叠数量，进而可以减少第一网络的发射信号和第二网络的发射信号对定位模块接收信号的干扰，提高定位模块的性能。
可选的，所述在所述目标频率对所述第一工作频段产生干扰的情况下，调整所述第一网络的发射时隙和所述第二网络的发射时隙的至少一者，可以包括：
在所述目标频率对所述第一工作频段产生干扰的情况下，调整所述第一网络的发射时隙和所述第二网络的发射时隙的至少一者，直至所述第一网络的发射时隙和所述第二网络的发射时隙的重叠数量达到最小。
本实施例中，为了进一步减少第一网络的发射信号和第二网络的发射信号对定位模块接收信号的干扰，可以最大限度的错开第一网络的发射时隙和第二网络的发射时隙，也即使第一网络的发射时隙和第二网络的发射时隙的重叠数量达到最小。
例如，在一周期内第一网络的发射时间和第二网络的发射时间之后小于或等于该周期时长的情况下，可以调整第一网络的发射时隙和第二网络的发射时隙的至少一者，使得调整后的第一网络的发射时隙和第二网络的发射时隙完全错开，也即第一网络的发射时隙和第二网络的发射时隙的重叠数量为0。例如，如图6所示，调整前4G发射时隙和5G发射时隙之间存在4个重叠时隙，调整后4G发射时隙和5G发射时隙之间不存在重叠时隙。
又例如，在一周期内第一网络的发射时间和第二网络的发射时间之后大于该周期时长的情况下，可以调整第一网络的发射时隙和第二网络的发射时隙的至少一者，使得调整后的第一网络的发射时隙和第二网络的发射时隙的重叠数量最小，例如，如图7所示，调整前4G发射时隙和5G发射时隙之间存在6个重叠时隙，调整后4G发射时隙和5G发射时隙之间存在2个重叠时隙。
本公开实施例在所述目标频率位于所述定位模块的工作频段内的情况下，调整所述第一网络的发射时隙和所述第二网络的发射时隙的至少一者，直至所述第一网络的发射时隙和所述第二网络的发射时隙的重叠数量达到最小，可以进一步减少第一网络的发射信号和第二网络的发射信号对定位模块接收 信号的干扰，提高定位模块的性能。
可选的，在第一网络的工作频率和第二网络的工作频率交调后得到的频率未位于第一工作频段内的情况下，可以返回执行步骤401，也可以结束流程，也可以进一步判断第一网络的工作频率和第二网络的工作频率交调后得到的频率是否与第一工作频段较为接近等。
可选的，所述方法还可以包括：
在所述目标频率未位于所述第一工作频段内的情况下，若所述目标频率和所述第一工作频段中的第一频率的差值小于预设差值，则调整所述第一网络的发射时隙和所述第二网络的发射时隙的至少一者，其中，所述第一频率为所述第一工作频段中最靠近所述目标频率的频率。
本实施例中，上述第一频率可以为第一工作频段中最靠近目标频率的频率，例如，在目标频率大于第一工作频段中的每个频率的情况下，上述第一频率可以是第一工作频段的最大频率；在目标频率小于第一工作频段的每个频率的情况下，上述第一频率可以是第一工作频段的最小频率。上述预设差值可以根据实际情况进行合理设置，例如，1MHZ、0.5MHZ等。
实际应用中，在目标频率未位于第一工作频段内的情况下，可以进一步判断目标频率和所述第一工作频段中的第一频率的差值是否小于预设差值。具体的，在目标频率和第一频率的差值小于预设差值的情况下，可以调整所述第一网络的发射时隙和所述第二网络的发射时隙的至少一者，以减少第一网络的发射时隙和第二网络的发射时隙的重叠数量，否则可以返回执行步骤401，也可以结束流程。
可选的，本实施例也可以通过计算目标频率和第一工作频段中各个频率的差值，在计算得到的差值中存在至少一个差值小于预设差值的情况下，确定目标频率和第一工作频段较为接近，此时可以调整所述第一网络的发射时隙和所述第二网络的发射时隙的至少一者，以减少第一网络的发射时隙和第二网络的发射时隙的重叠数量。可选的，在计算得到的差值中不存在差值小于预设差值的情况下，可以返回执行步骤401，也可以结束流程。
可选的，本实施例还可以结合定位模块的接收信号强度和目标频率是否与第一工作频段较为接近共同确定目标频率是否对第一工作频段产生干扰。 例如，可以在定位模块的接收信号强度小于或等于阈值，且目标频率与第一工作频段较为接近(例如，目标频率和所述第一工作频段中的第一频率的差值小于预设差值)的情况下，确定目标频率对第一工作频段产生干扰，并调整所述第一网络的发射时隙和所述第二网络的发射时隙的至少一者，以减少第一网络的发射时隙和第二网络的发射时隙的重叠数量，否则可以返回执行步骤401，也可以结束流程。这样可以提高干扰检测结果的准确性。
可选的，所述在所述目标频率对所述第一工作频段产生干扰的情况下，调整所述第一网络的发射时隙和所述第二网络的发射时隙的至少一者之后，所述方法还可以包括：
在所述第一重叠数量大于0的情况下，控制所述定位模块在目标时隙内停止接收所述第一工作频段的信号，其中，所述目标时隙包括调整后所述第一网络的发射时隙和所述第二网络的发射时隙之间的重叠时隙。
本实施例中，可以在调整后的第一网络的发射时隙和第二网络的发射时隙之间存在重叠时隙的情况下，在重叠时隙上控制定位模块停止从第一工作频段接收信号。例如，第一网络的工作频段为n78，第二网络的工作频段为B41，定位模块的第一工作频段为L5，若第一网络的工作频率和第二网络的工作频率的差值位于L5频段内，则可以停止定位模块接收L5频段的信号。
例如，参见图7，调整后4G发射时隙和5G发射时隙之间存在2个重叠时隙，在重叠时隙定位模块不接收信号，而在非重叠时隙定位模块接收信号。
可选的，在定位模块仅支持工作在第一工作频段的情况下，可以在重叠时隙上关闭定位模块，以节省耗电。在定位模块支持工作在至少两个频段的情况下，可以在重叠时隙上控制定位模块停止接收第一工作频段的信号，并控制定位模块在重叠时隙上接收第二频段的信号，其中，上述第二频段可以为所述定位模块所支持的频段中除第一工作频段之外的频段。例如，可以在第一网络的工作频率和第二网络的工作频率的差值位于L5频段内的情况下，控制GPS模块停止接收L5频段的信号，并控制GPS模块接收L1频段的信号进行定位，以保证定位功能。
本公开实施例通过在重叠时隙上停止定位模块接收第一工作频段的信号，不仅可以省电，还可以避免因第一工作频段的信号被严重干扰导致的定位结 果不准确。
可选的，本实施例还可以在一周期内重叠时隙的时长与周期时长的比值达到预设值的情况下，在该周期内停止定位模块接收第一工作频段的信号，这样可以进一步省电。需要说明的是，上述预设值可以根据实际情况下进行合理设置，例如，0.5或0.6等。
以下结合示例对本公开实施例进行说明：
参见图8，本公开实施例提供的干扰处理方法包括如下步骤：
步骤801、搜网驻留，建立4G/5G双连接。
该步骤中，移动终端可以是在NSA架构下，搜网驻留，建立4G和5G双连接。
步骤802、判断当前GPS L5是否工作。
该步骤中，上述判断GPS L5是否工作也即判断GPS模块是否工作在L5频段。具体的，在GPS L5工作的情况下，可以执行步骤803，否则可以执行步骤808。
步骤803、判断当前网络频段是否是n78和LTE B41。
该步骤中，判断移动终端当前连接网络的频段是否是n78和LTE B41。若是，则可以执行步骤804，否则可以执行步骤808。
步骤804、判断n78与LTE B41频率差值是否落在GPS L5频段内。
步骤805、判断n78与LTE B41发射时间之和是否大于周期时长。
该步骤中，上述判断n78与LTE B41发射时间之和是否大于周期时长，也即判断一个周期内n78与LTE B41发射时隙之和是否占满整个周期内的时隙。
具体的，在n78与LTE B41发射时间之和大于周期时长的情况下，可以执行步骤807，否则可以执行步骤806。
步骤806、调整发射时隙，保证不同时发射。
该步骤中，在n78与LTE B41发射时间之和小于或等于周期时长的情况下，可以错开移动终端当前连接的两个网络的发射时隙，使得没有发射时隙存在双发射信号共同发射的情况，也就不存在交调干扰，从而不会对GPS L5造成干扰，如图6所示。
步骤807、最大限度错开发射时隙，不可避开时间内GPS不接收。
该步骤中，在n78与LTE B41发射时间之和大于周期时长的情况下，可以最大限度错开移动终端当前连接的两个网络的发射时隙，使得移动终端当前连接的两个网络的发射时隙的重叠数量最小，同时GPS L5在重叠时隙关闭，避免干扰，如图7所示。
步骤808、保持当前连接状态。
综上，本公开实施例可以解决相关技术中在NSA架构下n78和LTE B41双上行干扰GPS L5的问题，可以减少在NSA架构下n78和LTE B41双上行对GPS L5的干扰，提高定位性能。

存储器1009可用于存储软件程序以及各种数据。存储器1009可主要包括存储程序区和存储数据区，其中，存储程序区可存储操作系统、至少一个功能所需的应用程序(比如声音播放功能、图像播放功能等)等；存储数据区可存储根据手机的使用所创建的数据(比如音频数据、电话本等)等。此外，存储器1009可以包括高速随机存取存储器，还可以包括非易失性存储器，例如至少一个磁盘存储器件、闪存器件、或其他易失性固态存储器件。
处理器1010是移动终端的控制中心，利用各种接口和线路连接整个移动终端的各个部分，通过运行或执行存储在存储器1009内的软件程序和/或模块，以及调用存储在存储器1009内的数据，执行移动终端的各种功能和处理数据，从而对移动终端进行整体监控。处理器1010可包括一个或多个处理单元；可选的，处理器1010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1010中。
移动终端1000还可以包括给各个部件供电的电源1011(比如电池)，可选的，电源1011可以通过电源管理系统与处理器1010逻辑相连，从而通过电源管理系统实现管理充电、放电、以及功耗管理等功能。
另外，移动终端1000包括一些未示出的功能模块，在此不再赘述。
可选的，本公开实施例还提供一种移动终端，包括处理器1010，存储器1009，存储在存储器1009上并可在所述处理器1010上运行的计算机程序，该计算机程序被处理器1010执行时实现上述干扰处理方法实施例的各个过程，且能达到相同的技术效果，为避免重复，这里不再赘述。
本公开实施例还提供一种计算机可读存储介质，计算机可读存储介质上存储有计算机程序，该计算机程序被处理器执行时实现上述干扰处理方法实施例的各个过程，且能达到相同的技术效果，为避免重复，这里不再赘述。其中，所述的计算机可读存储介质，如只读存储器(Read-Only Memory，ROM)、随机存取存储器(Random Access Memory，RAM)、磁碟或者光盘等。
