Description

一种调节天线切换的方法和装置 技术领域
本公开涉及但不限于通信技术领域，尤其是一种调节天线切换的方法和装置。
背景技术
集成功能多、支持频段多已成为智能移动通讯终端的发展趋势，带给用户良好体验。由于在有限尺寸内集成的无线频段越来越多，从700MHz～5GHz频率范围宽，同时移动终端功能部件越来越多，比如：液晶显示器(LCD，Liquid Crystal Display)、触摸屏、马达、扬声器(Speaker)、主/副摄像头、闪光灯、通用串行总线(USB，Universal Serial Bus)、指纹识别等。
发明内容
以下是对本文详细描述的主题的概述。本概述并非是为了限制权利要求的保护范围。
在诸多应用场景下，由于移动终端的电路设计或自身固有缺陷，难免会遇到难以有效减轻或者避免的某些频段受某些部件应用的干扰。
移动终端上为了增强接收性能，通常可以设计保留有第一天线、即主集天线和第二天线、即分集天线，其中主集天线可以实现移动终端的无线信号发射和接收传输，而分集天线可以实现移动终端接收无线信号；默认状态下，主集天线与分集天线都可以是打开正常工作的。主集天线和分集天线一般可以分别位于移动终端的不同位置，与某个功能部件的距离通常可以有相对的远近，例如前置摄像头可以靠近位于移动终端顶部的分集天线，远离位于底部的主集天线。
在移动终端开发过程中发现前置摄像头开启时对多个制式多个频段的分集天线的耦合接收灵敏度有严重干扰，有的频段受扰幅度高达20dB，通过电路滤波及摄像头驱动修改，仍不能使所有频段的受扰幅度均改善至可接受 范围内。前置摄像头开启的场景下，受扰幅度过大会带来很不好的用户体验，甚至可能引起语音通话无法接通等严重故障。
虽然，前置摄像头的干扰大致是影响分集天线，但由于主集天线和分集天线正常情况下可以是同时开启的，当分集天线受到严重干扰时，会把影响带到整个移动终端的接收性能，即分集天线的干扰也会影响到主集天线，这会严重影响用户体验。

本公开的较佳实施方式
下面结合附图对本公开的实施方式进行描述。
在本公开的各种实施例中，可以实时检测第二天线的接收灵敏度，检测到移动终端接收无线信号并开启至少一个功能部件后，确定接收灵敏度下降 幅度；根据所述接收灵敏度下降幅度判断是否满足实施条件，如果满足，则对第一天线和所述第二天线进行切换。
本公开涉及的领域例如：移动终端的无线通信技术领域。
图1为本公开实施例提供的一种调节天线切换的方法的流程示意图；如图1所示，所述方法，包括：
步骤101、实时检测第二天线的接收灵敏度，检测到移动终端接收无线信号并开启至少一个功能部件后，确定接收灵敏度下降幅度；
可选地，所述移动终端，可以包括，第一天线和第二天线；所述第一天线和所述第二天线可以分别设置在所述移动终端的不同位置；其中，所述第一天线可以为主集天线，所述第二天线可以为分集天线。
图2为本公开实施例提供的一种移动终端的天线分布示意图；如图2所示，移动终端的第一天线和第二天线可以分别位于移动终端的不同位置，其中，第一天线可以为主集天线，位于终端底部区域202；第二天线可以为分集天线，位于终端顶部区域201。
所述主集天线，可以设置为：发送和接收射频信号；所述分集天线，可以设置为：接收信号而不发送信号；基站可以设置为：把从分别对应于主集天线和分集天线的两个接口收到的信号进行合并处理，从而获得分集增益。
默认状态下，移动终端中的主集天线与分集天线都可以是正常打开工作的状态，移动终端使用过程中，移动终端可以实时检测所述第一天线接收信号时的信号强度和所述第二天线接收信号时的信号强度，确保第一天线始终保持正常使用，若连接无线信号后检测不到第一天线的接收信号，则可以发出错误警报。
所述移动终端，可以包括：智慧手机、移动电话、平板电脑、智能通讯终端等同时具有主集天线和分集天线的设备。
可选地，所述检测到移动终端接收无线信号并开启至少一个功能部件之后，所述方法还可以包括：
移动终端确定所述无线信号的频段和开启的功能部件，判断所述无线信号的频段和开启的功能部件是否对应保存在部件干扰查询表，这里，所述部 件干扰查询表是对应保存有对所述第二天线产生干扰的频段和功能部件的表格；
确定所述无线信号的频段和开启的功能部件保存在部件干扰查询表时，继续检测第二天线的接收灵敏度，确定所述接收灵敏度下降幅度。
这里，接收灵敏度下降幅度对应的频段和开启的功能部件可以为在移动终端生产测试过程中通过多次信号检测确定的会对第二天线的接收灵敏度造成影响的频段和功能部件，可以将两者的对应关系预先设定并保存在移动终端的状态池内。即移动终端可以通过查询所述部件干扰查询表确定接收灵敏度下降幅度对应的频段和开启的功能部件。
所述无线信号可以为运营商提供的移动数据信号。所述无线信号可以是不同制式下不同频段的信息。例如：中国联通LTE是Band3为主，中国电信LTE是Band1为主；这里，Band1表示1920MHz-1980MHz，Band3表示1710MHz-1785MHz，频段信息可以在第三代合作伙伴计划(3GPP，3rd Generation Partnership Project)频段划分协议中规定。
所述功能部件，可以包括：移动终端的扬声器(Speaker)、主摄像头、副摄像头、闪光灯、通用串行总线(USB，Universal Serial Bus)、指纹识别模块等。
表1为本公开实施例中提供的一种移动终端状态池里保存的部件干扰查询表，如表1所示，可以包括第二天线的接收灵敏度下降幅度K11、K12、……Kij，接收灵敏度下降幅度对应的频段B1、B2、……、Bj和开启的功能部件A1、A2、……、Ai。
  A1 A2 …… Ai
B1 K11 K21 …… Ki1
B2 K12 K22 …… Ki2
…… …… …… …… ……
Bj K1j K2j …… Kij
表1
可选地，所述确定接收灵敏度下降幅度，可以包括：
移动终端根据实时检测的第二天线的接收灵敏度，确定接收无线信号并开启至少一个功能部件后的接收灵敏度；
根据移动终端接收无线信号并开启至少一个功能部件之前和之后检测获得的接收灵敏度确定所述第二天线的接收灵敏度下降幅度，并保存在所述移动终端状态池的部件干扰查询表。
步骤102、根据所述接收灵敏度下降幅度判断是否满足实施条件，如果满足，则对第一天线和所述第二天线进行切换。
可选地，所述实施条件，可以包括：所述第二天线的接收灵敏度下降幅度大于预设幅度阈值；
所述步骤102，可以包括：
移动终端确定所述第二天线的接收灵敏度下降幅度后，判断所述接收灵敏度下降幅度是否大于预设幅度阈值；
确定所述接收灵敏度下降幅度大于预设幅度阈值时，满足实施条件，所述移动终端关闭所述第二天线，保持所述第一天线正常使用；
确定所述接收灵敏度下降幅度小于或等于预设幅度阈值时，不满足实施条件，所述第一天线和所述第二天线保持正常使用。
图3为本公开实施例提供的另一种调节天线切换的方法的流程示意图；如图3所示，所述方法，可以包括：
步骤301、实时检测第二天线的接收灵敏度，检测到移动终端接收无线信号并开启至少一个功能部件后，确定接收灵敏度下降幅度；
步骤302、根据所述接收灵敏度下降幅度判断是否满足实施条件，如果满足，则对第一天线和所述第二天线进行切换；
这里，步骤301和步骤302与图1所示的步骤101、步骤102可以相同，这里不再赘述。
步骤303、检测所述第二天线的接收灵敏度下降幅度对应的无线信号的频段和开启的功能部件是否有至少一个不再工作；
确定所述无线信号的频段和开启的功能部件有至少一个不再工作时，打 开所述第二天线，保持所述第一天线正常使用。
可选地，移动终端检测到所述第二天线的接收灵敏度下降幅度对应的无线信号的频段不再工作、即不再连接此频段的无线信号，或开启的功能部件不再工作，或不再连接此频段的无线信号且开启的功能部件不再工作，则可以重新打开所述第二天线，并可以保持所述第一天线正常使用，使得移动终端第一天线和第二天线打开正常工作。
针对上述方法，举例说明：
部件干扰查询表内可以保存有主摄像头和频段Band5的对应关系，表示移动终端的主摄像头启用时，会对移动终端的LTE(Long Term Evolution，长期演进)Band5(Band表示某段可用的频段，如：中国联通LTE是Band3为主，中国电信LTE是Band1为主)的第二天线、即分集天线的接收灵敏度产生严重干扰。
假设实施条件为超过设定幅度阈值K、假设K＝10dB，功能部件称为A、即主摄像头，无线制式的频段称为B、即Band5，则可以有如下场景：
第一：当功能部件A和频段B同时工作时，接收灵敏度下降幅度设为Ki，假设Ki约为20dB；
移动终端检测到Ki大于K时，即满足实施条件，可以启动实施，移动终端可以将第二天线关闭，同时第一天线仍可以保持正常使用；
当移动终端检测到同时工作的功能部件A和频段B有任何一方或者双方不再工作时，可以重新启用所述第二天线，使得所述第二天线与所述第一天线正常叠加使用。
第二：当功能部件A和频段B同时工作，如果Ki小于、等于K时，则不满足实施条件，移动终端可以不做实施动作，所述第一天线和所述第二天线可以保持正常叠加使用。
第三：当功能部件A和频段B不同时工作时，可以不启动移动终端的实施动作，所述第一天线和所述第二天线可以保持正常叠加使用。
移动终端在开启某种部件功能应用时，不同无线制式下不同频段的接收 灵敏度受扰程度可以被已知手段检测并记录存储在终端的状态池里，设定一个阈值K；当检测记录的接收灵敏度受扰程度、以接收灵敏度下降幅度表示，超出阈值K时，即表明接收信号质量严重受损，会影响用户体验。通过上述实施例，可以在用户启用移动终端的某些部件功能应用导致接收信号急剧下降时，使得移动终端依然能够保持正常通信；防止由于分集天线受到严重干扰时，把这种影响带入到整个移动终端。
图4为本公开实施例提供的又一种调节天线切换的方法的流程示意图；可选地，如图4所示，假设某种功能部件称为A，移动终端无线制式的某个频段称为B，实施条件的设定幅度阈值为K，移动终端无线制式的频段B在功能部件A启用的场景下，该频段B的接收灵敏度下降幅度设为Ki，运用图1所示的方法，判断是否满足实施条件，可以包括以下场景和对应的切换方法：
场景401：当功能部件A工作、频段B不工作时，不启动实施，第一天线和第二天线保持正常叠加使用；
场景402：当功能部件A不工作、频段B工作时，不启动实施，第一天线和第二天线保持正常叠加使用；
场景403：当功能部件A、频段B均工作时，移动终端读取由已知手段检测并存储在终端状态池里的部件干扰查询表，当Ki小于或等于K时，则不满足实施条件，移动终端不做实施动作，第一天线和第二天线保持正常叠加使用；
场景404：当功能部件A、频段B均工作时，移动终端读取由已知手段检测并存储在终端状态池里的部件干扰查询表，当Ki大于K时，满足所述实施条件，启动实施，即移动终端将所述第二天线关闭，同时所述第一天线仍保持正常使用；
之后，移动终端可以继续检测接收灵敏度下降幅度对应的无线信号的频段B和开启的功能部件A是否有至少一个不再工作，当检测到同时工作的功能部件A和频段B有任何一方或者双方不再工作时，可以重新启用第二天线，使得第二天线与第一天线正常叠加使用。
