技术领域
本申请涉及通信领域，尤其涉及一种天线配置方法和设备。
背景技术
智能手机通常使用WIFI网络执行业务传输，此时还可能连接蓝牙外设传输蓝牙数据，例如用户可能会通过蓝牙外设收听音频数据，或用蓝牙手柄操控游戏。在上述情形下，WIFI信号和蓝牙信号一直以来共用一根天线进行传输。但是随着手机上蓝牙外设(例如手表，耳机，游戏手柄，手写笔等)的多样化和使用频率的提高，蓝牙和WIFI共用天线的方案会存在资源抢占问题。尤其在一些WiFi和蓝牙高使用率的场景中，上述方案可能导致通信卡顿、延迟和速率变差等现象，越来越难满足用户需求。
发明内容
本申请提供一种天线配置方法和设备，能够实现高速业务下的蓝牙信号和WIFI信号分别采用独立天线进行传输。
为达到上述目的，本申请采用如下技术方案：
第一方面，本申请提供一种通信方法，应用于电子设备，电子设备包括第一天线集合，第一天线集合包括至少一个天线，该第一天线集合的天线用于第一信号和第二信号通信；第一信号为WIFI信号，第二信号为蓝牙信号，或第一信号为蓝牙信号，第二信号为WIFI信号；述电子设备还包括第二天线集合，所述第二天线集合包括多个天线；该第二天线集合中的天线用于传输蜂窝信号；当满足第一预设条件时，第一信号使用第二天线集合中的至少一个天线进行传输,同时第二信号独立使用所述第一天线集合中的天线进行传输；第二天线集合中的至少一个天线包括第一天线，第一天线为下述天线之一：第二天线集合中与所述第一天线集合的任一个天线的隔离度最大的天线；第二天线集合中与所述第一天线集合的任一个天线的距离最大的一个天线；第二天线集合中与第一天线集合的任一个天线呈对角线布置的天线；满足第一预设条件之前所述第二天线集合中关闭的天线；第二天线集合中除去被遮挡的天线之外的天线。由此，通过隔离度、距离、对角线位置等条件对切换的目标天线进行限定，使蓝牙信号和WIFI信号采用独立天线传输时干扰尽可能达到最小；通过是否被遮挡对切换的目标天线进行限定，保证WIFI信号或蓝牙信号切换到蜂窝天线后的信号质量；通过是否关闭对目标天线进行限定，保证WIFI信号或蓝牙信号切换到蜂窝天线后，对蜂窝天线的传输 影响最小。
在一种可能的实现方式中，第一天线集合和第二天线集合的任一天线的工作频段为2.3GHz至2.7GHz。由于天线可调频率有限，由此保证切换的目标蜂窝天线的频率可以调谐到蓝牙信号或WIFI信号的频率。
在一种可能的实现方式中，第二天线集合中的至少一个天线与第一天线集合的任一天线的隔离度大于预设隔离度阈值。由此，当多个天线的隔离度均满足要求时，可以选择隔离度满足要求的多个天线，不用局限于选择隔离度最大的天线，增加了选择目标天线的灵活性。
在一种可能的实现方式中，第一预设条件包括WIFI业务和蓝牙业务冲突。
在一种可能的实现方式中，第一信号和所述第二信号所属的WIFI业务和蓝牙业务冲突包括第一信号和所述第二信号所属的WIFI业务和蓝牙业务同时存在。由此，当判断WIFI业务和蓝牙业务可能在时域上互相抢占时，及时将蜂窝天线给WIFI业务或蓝牙业务使用。
在一种可能的实现方式中，第一信号和所述第二信号所属WIFI业务和蓝牙业务冲突包括：WIFI业务对应的WIFI信道的信道状态和蓝牙业务对应的蓝牙信道的信道状态至少一个处于为繁忙。由此，当判断WIFI业务和蓝牙业务采用时分复用天线方案不能满足业务要求时，及时将蓝牙业务或WIFI业务切换到蜂窝天线。

在一种可能的实现方式中，第一天线为主集天线时，将分集天线调整为用户识别卡的主 集天线。由此，当主集天线被WIFI信号或蓝牙信号占用时，通过将分集天线调整为主集天线，减少了对SIM卡通信质量的影响。
在一种可能的实现方式中，电子设备具有多个卡槽，用于放置多个用户识别卡，多个用户识别卡包括主用户识别卡和副用户识别卡，第二天线集合中的第一部分天线用于收发主用户识别卡的蜂窝信号，第二天线集合中的第二部分天线用于收发副用户识别卡的蜂窝信号，第一天线属于第一部分天线或第二部分天线；为主用户识别卡和副用户识别卡分配第二天线集合中除第一天线以外的天线。
在一种可能的实现方式中，为主用户识别卡和副用户识别卡分配第二天线集合中除第一天线以外的天线包括为主用户识别卡分配第三部分天线，为副用户识别卡分配第四部分天线；第三部分天线与第一部分天线不同；且第四部分天线和第二部分天线不同。由此，当某个蜂窝天线被蓝牙或WIFI占用时，为了保证主用户识别卡的通信质量，双SIM卡重新分配剩余天线。
在一种可能的实现方式中，当满足第二预设条件时，在第一天线上停止传输第一信号，且第一天线集合的天线恢复用于第一信号和第二信号通信。
在一种可能的实现方式中，第二预设条件包括如下条件中的一个或多个：WIFI业务和所述蓝牙业务的冲突解除；蜂窝业务为高优先级业务；第二天线集合的至少一个天线的信号强度小于第一信号强度阈值。由此，当达到预设条件时，可以及时切换回初始天线传输状态并恢复蜂窝天线配置。

无线通信模块160可以提供应用在电子设备100上的包括无线局域网(wireless local area networks，WLAN)(如无线保真(wireless fidelity，Wi-Fi)网络)，蓝牙(bluetooth，BT)，全球导航卫星系统(global navigation satellite system，GNSS)，调频(frequency modulation，FM)，近距离无线通信技术(near field communication，NFC)，红外技术(infrared，IR)等无线通信的解决方案。无线通信模块160可以是集成至少一个通信处理模块的一个或多个器件。无线通信模块160经由天线2接收电磁波，将电磁波信号调频以及滤波处理，将处理后的信号发送到处理器110。无线通信模块160还可以从处理器110接收待发送的信号，对其进行调频，放大，经天线2转为电磁波辐射出去。
在一些实施例中，电子设备100的天线1和移动通信模块150耦合，天线2和无线通信模块160耦合，使得电子设备100可以通过无线通信技术与网络以及其他设备通信。所述无线通信技术可以包括全球移动通讯系统(global system for mobile communications，GSM)，通用分组无线服务(general packet radio service，GPRS)，码分多址接入(code division multiple access，CDMA)，宽带码分多址(wideband code division multiple access，WCDMA)，时分码分多址(time-division code division multiple access，TD-SCDMA)，长期演进(long term evolution，LTE)，BT，GNSS，WLAN，NFC，FM，和/或IR技术等。所述GNSS可以包括全球卫星定位系统(global positioning system，GPS)，全球导航卫星系统(global navigation satellite system，GLONASS)，北斗卫星导航系统(beidou navigation satellite system，BDS)，准天顶卫星系统(quasi-zenith satellite system，QZSS)和/或星基增强系统(satellite based augmentation systems，SBAS)。

电子设备100，可以是例如图2中的手机100，手机100通过WIFI网络连接路由器200，且同时手机100通过蓝牙连接方式连接到无线耳机300或游戏手柄400，图2的一个场景可以是用户正在通过WIFI网络打游戏，其手机连着蓝牙手柄。另一个场景可以是用户正在通过WIFI进行视频通话，带着蓝牙耳机。对于游戏场景或视频通话场景，音视频数据高速传输，蓝牙业务和WIFI业务对传输服务质量的要求均较高，尤其实时性的要求较高。现有技术中，手机的蓝牙信号和WIFI信号以时分复用的方式共用一根天线，导致同一时段手机WIFI业务和蓝牙业务不能同时工作，并且蓝牙业务优先级较高，随时可能打断WIFI业务。例如对于视频通话场景，手机正在通过WIFI收发音视频数据，而手机需要给蓝牙耳机传数据的时候会打断WIFI的音视频数据收发，用户会感到声音或画面卡顿。又例如，对于游戏场景，手柄的控制数据需要通过蓝牙传输到手机，游戏画面数据通过WIFI传输到手机，手机与路由器之间的WIFI传输和手柄与手机之间的蓝牙传输存在冲突，从用户的角度看，游戏画面存在卡顿。
图3(a)和图3(b)为游戏场景的一个实例，图3(a)是用户使蓝牙外设连接到手机，同时使用手机打游戏的界面。游戏界面的右上角显示游戏延时为92ms。而在图3(b)中，在用户关掉手机蓝牙服务后，界面上的游戏延时降低为11ms。可见，当前WIFI和蓝牙时分复用一根天线的工作机制，不利于二者均是高速业务的场景。
如图4(a)-4(c)所示，在本申请的一个实施例中，手机401、402和403都配置了6根2.3GHz至2.7GHz范围内的天线，可以理解的是，手机中2.3-2.7GHz的天线可以多于或少于6根，手机还存在未示出的其余频段的天线。在手机401中，无线保真(Wireless Fidelity， 简称为“WiFi”)模块使用天线Ant4和Ant5，支持2×2多输入多输出(Multiple Input Multiple Output，简称为“MIMO”)技术，蓝牙模块和WIFI模块共享天线Ant4。在手机402中，蓝牙模块和WIFI模块共享天线Ant6，蜂窝模块高频频段占用天线Ant1到Ant5。在手机403中，蓝牙和WIFI共享天线Ant4和天线5，均支持2×2MIMO技术，蜂窝模块高频频段占用天线Ant1-3和Ant6，支持4×4MIMO技术。其中MIMO技术主要通过多天线(例如，4天线)及多射频通道(例如，4接收通道)等硬件条件，搭配芯片基带算法以提升使用者的数据吞吐体验。
如图5所示，对于单个共享天线(例如图4(a)中的手机401的Ant4)，蓝牙模块51和WIFI模块52通过一个开关53，时分复用该共享天线54。当开关53的通路导通到蓝牙模块51时，天线54收发蓝牙信号；当开关53的通路导通到WIFI模块52时，天线54收发WIFI信号。
蓝牙信号和WIFI信号的时分复用方案如图6所示，图6的复用方式使电子设备实现了在一根天线上收发蓝牙业务和WIFI业务。在图6中，蓝牙或WIFI在各自的工作时间段(Working Time)内进行数据传输，在空闲时间段(Idle Time)内则不进行数据传输。而蓝牙业务和WIFI业务在任意时间段只能有一种业务处于工作时间段，蓝牙和WIFI交替占用时域资源。
可见，现有的天线布局仍然无法满足用户对于无线性能的要求，因为WIFI信号和蓝牙信号时分复用一根天线，会存在天线资源的抢占问题。当手机运行游戏APP时，手机同时通过WIFI连接路由器，通过蓝牙连接游戏手柄，游戏APP对于信号传输的实时性要求高，因此WIFI和蓝牙分时复用一根天线，会导致信号的延迟，使得用户玩游戏时的体验不佳。如果在手机上增加一根用于传输蓝牙或WIFI的独立天线，不仅会增加成本，还可能影响ID外观和产品结构稳定性。此外，增加一根天线，导致七根同频天线在有限的手机空间中设置，对于天线之间的隔离度指标影响也很大，进而恶化手机整体无线性能。
由上可知，如果蓝牙和WIFI不进行分时复用，则蓝牙和WIFI占用的时域资源将大大增加，有利于解决高速业务场景的资源抢占问题。而现有手机中蜂窝模块占用的天线数量较多，因此本申请将蓝牙信号或WIFI信号切换到蜂窝模块占用的天线中的一个或多个天线进行传输，在不增加天线的基础上，同时收发蓝牙业务和WIFI业务。
图7示出了根据本申请实施例的配置天线的方法，具体包括：
S101.实时统计WIFI信道的业务指标；
业务指标可以是业务吞吐量，信道占用率和业务时延等指标，还可以是其它常用的表示信道繁忙程度的指标，可以统计一种或多种业务指标，这里不做限定。业务吞吐量为单位时间内通过信道的数据量；业务时延为从发送端开始发送数据至接收端完全接收这个数据的时间间隔；信道占用率为信道平均被占用的程度，例如如果信道占用率是10％，表示信道平均在10％的时间处于被占用的状态。
可以理解的是，实时统计WIFI信道的业务指标可以是每隔一个预设短周期T1进行统计。
S102.实时统计蓝牙信道的业务指标；
实时统计蓝牙信道的业务指标可以是每隔一个短周期T2进行统计。T1和T2可以相同，也可以不同。S101和S102可以同时执行，也可以先后执行。
S103.判断WIFI业务和蓝牙业务是否冲突；
业务指标统计结果可以表示一段时间内的信道业务繁忙程度。作为一个实施例，将任意一个业务指标在一段时间内的均值作为其业务指标统计结果。例如，对于WIFI业务来说， 可以将一段时间内的业务吞吐量均值作为WIFI信道的业务指标统计结果。作为一个实施例，可以将每一种业务指标设置相应的权重，并将多个业务指标在一定时间内的均值加权求和得出一个业务指标统计结果。作为另一个实施例，可以将一段时间统计到的任意一个业务指标作为业务指标统计结果。
可以通过上述方式获得WIFI信道和蓝牙信道的业务指标统计结果，分别根据WIFI信道和蓝牙信道的业务指标统计结果判断WIFI业务和蓝牙业务的信道状态；根据WIFI业务和蓝牙业务的信道状态判断WIFI业务和蓝牙业务是否冲突。
具体为，当WIFI信道的业务指标统计结果大于预设第一统计结果阈值时，电子设备确定WIFI业务的信道状态为繁忙状态，否则为空闲状态；当蓝牙信道的业务指标结果大于第二统计结果阈值时，确定蓝牙业务的信道状态为繁忙状态，否则为空闲态。第一统计结果阈值和第二统计结果阈值可以相同，也可以不同。
当WIFI业务和蓝牙业务的信道状态均为繁忙状态时，则确定WIFI业务和蓝牙业务冲突；也可以是，当WIFI业务和蓝牙业务的信道状态有一个为繁忙状态时，就确定WIFI业务和蓝牙业务冲突。
又例如，可以根据业务指标统计结果所在的阈值区间设置不同的档位，包括空闲，较空闲，较忙，繁忙等档位，将蓝牙业务和WIFI业务根据不同的档位进行组合判断，可以是：当蓝牙业务和WIFI业务有一个为繁忙时，判断两者冲突，或当蓝牙业务和WIFI业务的信道状态均为较忙时，判断两者冲突。可以理解的是，本领域技术人员还可以采用其它常用的档位设定方式和冲突判断方式，这里不做限定。
可以每隔一个预设的周期T3执行S103。T3可以与T1和T2相同，也可以不同。例如T3可以大于T1和T2，以便将一段时间的蓝牙和WIFI信道的业务指标进行统计，再进行冲突判断。
上述步骤还可以设定执行条件。例如，根据电子设备的屏幕状态确定是否执行S101-S103的冲突检测流程。可以是当手机处于亮屏状态时执行S101-S103的冲突检测流程。又例如在特定时间段执行上述冲突检测流程，可以根据用户习惯进行统计得出该特定时间段。例如统计发现10:00pm到11:00pm，用户通常在打游戏，则在该时间段开启业务冲突检测。又例如，排除用户的工作时间或睡眠时间开启冲突检测。又例如可以根据WIFI模块的工作频段以及蓝牙模块的工作状态决定是否开启业务冲突检测。WIFI模块可以使用2.4GHz或5GHz频段，当WIFI模块使用5GHz频段则与蓝牙模块的工作频段不冲突，当WIFI模块使用2.4GHz频段则与蓝牙模块的工作频段相似，可能发生业务冲突。因此，可以在WIFI模块使用2.4Ghz频段，且蓝牙模块工作时，执行冲突检测。
如果电子设备确定WIFI业务和蓝牙业务冲突，则执行S105，否则重新执行S101和S102。作为另一个实施例，电子设备确定蓝牙业务和蜂窝业务冲突持续时间达到冲突检测时间阈值，才执行S105。否则重新执行S101和S102。在执行S105之前，可选的，还可以选择性的执行S104。
S104.判断蜂窝业务是否处于繁忙状态；
实时统计蜂窝信道的业务指标，并获得蜂窝业务的业务指标统计结果。蜂窝信道的业务指标可以是数据吞吐量，信道占用率和业务时延等指标，还可以是其它常用的业务指标，可以统计一种或多种业务指标，这里不做限定。可以理解的是，实时统计蜂窝信道的业务指标可以是每隔一个预设短周期T4进行统计。T4和T1、T2、T3可以相同，也可以不同。蜂窝 业务的业务指标统计结果的获得过程和S103类似，此处不再赘述。
根据业务指标统计结果判断蜂窝业务的信道状态。当蜂窝业务指标结果大于预设第三统计结果阈值时，电子设备确定蜂窝业务的信道状态为繁忙状态，否则为空闲状态；
作为另一个实施例，可以根据电子设备正在执行的业务类型判断蜂窝业务是否繁忙，例如电子设备正在蜂窝网络中进行通话，则电子设备判断蜂窝业务的信道状态为繁忙。
如果蜂窝业务的信道状态是繁忙状态，继续执行S101和S102。否则执行S105。
作为另一个实施例，如果蜂窝业务信道的空闲状态持续预定的可占用时间阈值，则执行S105。
在图8中，作为S101-S103的替换，可以执行S101'。
S101’根据业务类型判断策略判断WIFI业务和蓝牙业务是否冲突。具体为，当确定电子设备在WIFI状态下正在执行的业务属于特定业务类型，且电子设备与其它蓝牙设备之间存在数据传输或电子设备与其它蓝牙设备之间存在通信连接时，电子设备确定WIFI业务和蓝牙业务冲突，并执行S105，可选的执行S104。例如可以将游戏、视频通话等高速率业务归为特定业务类型。蓝牙设备可以是蓝牙手柄、蓝牙耳机或蓝牙音箱等，非穷举。一个场景可以是，用户正在打游戏，电子设备检测到其正在执行的业务为游戏类业务，属于特定业务类型，且电子设备检测到其与蓝牙手柄存在连接，或检测到与蓝牙手柄存在数据交互，则电子设备确定WIFI业务和蓝牙业务存在冲突。又例如，电子设备确定当前正运行特定应用程序或特定应用程序内的特定进程，且电子设备判断其与其它蓝牙设备之间存在数据传输或其与其它蓝牙设备之间存在通信连接，则确定WIFI业务和蓝牙业务冲突。特定应用程序可以为运行高速业务的应用程序，例如，电子设备可以将用户安装的游戏应用程序、视频通话类应用程序定义为特定应用程序，又例如，电子设备将聊天应用程序中的视频通话进程定义为特定应用程序中的特定进程。
作为另一个实施例，当蓝牙业务和WIFI业务同时存在时，电子设备判断蓝牙业务和WIFI业务冲突。此实施例可以使蓝牙业务或WIFI业务尽可能使用不同天线进行传输。
S105.执行天线切换策略。
在图7和图8中，在执行S105时，具体执行如图9的流程：
S1051.在蜂窝天线中选取至少一个天线作为目标天线。
本申请的蜂窝天线特指在能够传输蜂窝信号的2.3GHz至2.7GHz频段中的天线，例如图4(a)中的天线Ant1到Ant4。另外，定义一个蜂窝天线集合，该蜂窝天线集合包括手机开机后的可用于传输2.3GHz至2.7GHz频段信号的所有的蜂窝天线。在蜂窝天线集合中确定一个或多个目标天线，目标天线用于在电子设备判决蓝牙业务和WIFI业务冲突后传输蓝牙信号或WIFI信号。
本申请的一个实施例中，上述确定目标天线的方法可以为：根据天线间的隔离度在蜂窝天线集合中确定目标天线。隔离度可以根据某一天线发射的信号功率与在另一天线接收的信号功率的比值确定，表明在某一天线的发射信号到另一天线的输出衰减程度该比值越大，说明隔离度越好。如果在蓝牙信号或WIFI信号切换到蜂窝天线后，二者的隔离度足够大，意味着蓝牙信号和WIFI信号在各占用一根天线时可以取消时分复用，且干扰程度仍然保持可接受范围。作为一个实施例，可以在蜂窝天线集合中选取与任一根共享天线的隔离度最大的一根天线作为目标切换天线，其中，共享天线为初始状态下WIFI模块和蓝牙模块共享的天线。作为另一个实施例，经测定，如果有N个天线均满足隔离度要求，即，N个天线满足到 共享天线中的任意一个天线的隔离度大于预设隔离度阈值，则电子设备也可以在蜂窝天线集合中选取N个天线作为目标天线，N大于1。例如，当N＝2时，电子设备有2个蜂窝天线和共享天线的隔离度满足信号传输要求，使得蓝牙信号或WIFI信号在切换后与共享天线上的信号干扰在可接受范围，则这两个蜂窝天线均可以作为目标天线。
以图4(a)和图4(c)中的手机为例，对上述实施例进行说明。具体地，以切换蓝牙信号的天线为例。在图4(a)的手机301中，初始状态下蓝牙模块和WIFI模块时分复用Ant4，确定与Ant4隔离度最大的天线Ant1为目标天线，切换后在Ant1传输蓝牙信号，且WIFI信号继续在Ant4和Ant5进行传输。Ant1与Ant4的隔离度足够大，因此在切换后尽管Ant1和Ant4同时工作，干扰也在可接受范围。对于图4(c)中的手机403，蓝牙模块和WIFI模块时分复用两根天线Ant4和Ant5，可以确定目标天线数目等于共享天线的天线数目，蓝牙信号在切换后可以占用两根原先传输蜂窝信号的天线。由于Ant1和Ant2与Ant4或Ant5的隔离度均满足要求，因此将Ant1和Ant2作为目标天线。切换后WIFI信号在天线Ant4和Ant5上传输，蓝牙信号在Ant1和Ant2上传输。如果只有Ant1的隔离度满足要求，也可以仅将Ant1作为两路蓝牙信号切换的目标天线，两路蓝牙信号指Ant4和Ant5上的蓝牙信号，则切换后WIFI信号在天线Ant4和Ant5上传输，蓝牙信号在Ant1上传输。
仍然以图4(a)中的手机401为例，还可以以切换WIFI信号的天线代替切换蓝牙信号的天线。对于手机401，WIFI信号在初始状态下使用两路天线Ant4和Ant5传输，可以在蜂窝天线中确定隔离度满足要求的Ant1和Ant2作为目标天线，在切换后使用Ant1和Ant2传输WIFI信号。切换后Ant4和Ant5上不再传输WIFI信号，蓝牙信号继续在Ant4上传输。当然，也可以仅将隔离度最大的天线Ant1作为目标天线供WIFI使用，切换后Ant4和Ant5上的天线不再传输WIFI信号。在目标天线仅有一个时，还可以在WIFI或蓝牙的发射功率足够小时，在切换后将Ant4用于传输蓝牙信号，Ant5上的WIFI信号保持传输，Ant1也用于传输WIFI信号，则WIFI信号和蓝牙信号不需要时分复用一个天线。
作为一个实施例，确定目标天线的方法可以为：确定处于关闭状态的天线为目标天线。如果蜂窝业务较为空闲，未使用所有天线，则存在处于关闭状态的天线。例如，蜂窝天线可以包括主集天线和分集天线，当蜂窝业务不繁忙时，可能将分集天线关闭。电子设备判断如果分集天线处于关闭状态，则将分集天线作为目标天线。
作为一个实施例，上述确定目标天线的方法可以为：可以判断蜂窝天线集合中的每一个天线是否被遮挡，在未被遮挡的天线中选择一个或多个天线作为目标天线。为了满足SAR(Specific Absorption Rate，电磁波吸收比值)标准，电子设备可内置SAR传感器，例如在图10(a)中，手机1001中安装有传感器1和传感器2，传感器1和传感器2为SAR传感器。当人体靠近SAR传感器附近的天线时，会引起电容的改变，进而可以通过SAR传感器检测其附近的天线是否被遮挡。传感器1和传感器2还可以为接近光传感器，或电容传感器等。初始状态下，例如天线Ant1到Ant4为蜂窝天线，Ant5和Ant6为WIFI和蓝牙的共享天线。用户正在打游戏，双手横握手机，如图10(b)，则传感器1和2检测出附近的天线Ant1和Ant3被用户的手遮挡，天线辐射性能降低。电子设备将蓝牙信号切换到Ant2，WIFI信号继续占用Ant4和Ant5。又例如，用户竖握手机，如图10(c)，传感器2检测出Ant1被遮挡，Ant3离手最远，辐射性能几乎不受手的影响，相比其他天线无线性能更好，可以将Ant3作为目标天线。
作为一个实施例，可以根据蜂窝天线集合中的每一个天线的信号强度确定目标天线，可以确定蜂窝天线集合中每一个天线的信号强度，如果某一天线的信号强度满足第一信号强度 条件，例如大于第一信号强度阈值，则说明该天线未被遮挡，可以作为目标天线。
在一个实施例中，可以同时根据天线间隔离度、遮挡状态、是否处于关闭状态等因素中的一种或多种因素在蜂窝天线集合中选取一个或多个天线作为目标天线。例如，在未被遮挡的蜂窝天线中选择距离第一天线隔离度最大的天线作为目标天线。又例如，在未被遮挡的天线中选取关闭的天线分集作为目标天线。在另一个实施例中，将隔离度，是否关闭，是否被遮挡等因素进行加权并给出综合打分，选取得分最高的天线作为目标天线，或者选取得分满足要求的天线作为目标天线。考虑上述因素的方式在此处不做限定。
作为另一个实施例，当蜂窝天线集合中与共享天线中任意一个天线的隔离度最大或距离最大的天线被遮挡时，不执行天线切换步骤S1052，而是继续执行S101和S102。例如，电子设备判断该天线RSRP小于第一预设RSRP阈值，则说明其被遮挡，不执行天线切换。又例如，当电子设备处于蜂窝的弱覆盖区域时，此时电子设备整体接收蜂窝信号的RSRP小于第二预设RSRP阈值，或电子设备判断蜂窝天线集合中任意一个天线的RSRP较弱，也不执行天线切换，而是继续执行S101和S102。
作为一个实施例，电子设备根据目标天线确定策略查表确定目标天线。目标天线确定策略可以是根据隔离度确定目标天线、根据手握状态确定目标天线等。例如，如果执行隔离度确定策略，则查表找到符合隔离度要求的天线作为目标天线。如果检测出手机处于横握状态，则查表找到横握状态下对应的目标天线。如果检测出手机处于竖握状态，则查表找到竖握状态下对应的目标天线。
作为另一个实施例，可以选取与任一根共享天线距离最大的天线为目标天线。
作为一个实施例，确定目标天线的方法还可以为：根据当前WIFI信号的发射功率和/或蓝牙信号的发射功率在蜂窝天线集合中确定目标天线。由于WIFI和蓝牙的工作频段重叠，两者并发时，容易产生干扰。例如，当手机距离路由器较远时，WIFI发射功率较高；或者当蓝牙外设离手机比较远，蓝牙的发射功率也会比较高。蓝牙或WIFI切换到目标天线后，如果天线间隔离度有限，外加取消了天线时分复用，蓝牙信号和WIFI信号同时传输容易产生较大干扰。此时对切换后的天线间隔离度要求较高，可以选取隔离度较大的天线作为目标天线。具体为，当蓝牙信号的发射功率大于预设蓝牙发射功率阈值或WIFI的发射功率大于预设WIFI发射功率阈值，在蜂窝天线集合中确定与共享天线中的任一天线隔离度最大的天线为目标天线。预设蓝牙发射功率阈值和预设WIFI发射功率阈值可以相同，也可以不同。例如对于图4(a)中的手机401，可以将Ant1作为目标天线。Ant1距离Ant4，Ant5较远，隔离度较好。如果手机距离路由器较近，或手机距离蓝牙外设较近，WIFI或蓝牙的发射功率较小，此时WIFI信号或蓝牙信号相对干扰较小，可以选取隔离度相对较小的天线作为目标天线。作为另一个实施例，电子设备还可以划分多个发射功率区间，并相应的采用不同的目标天线选取策略。即，可以设置当WIFI或蓝牙发射功率在不同的数值区间内时确定可选取的目标天线范围有所不同，所选取的目标天线范围与共享天线的隔离度可以与WIFI或蓝牙的发射功率相关。
在本申请的一个实施例中，以判断WIFI发射功率为例，当WIFI信号的发射功率属于第一发射功率值范围时，可以不进行天线切换，蓝牙信号和WIFI信号继续时分复用原天线。当WIFI信号的发射功率属于第二发射功率值范围时，在蜂窝天线集合中选取距离第一天线隔离度最大的天线为目标天线，当WIFI信号的发射功率属于第三发射功率值范围时，除了可以选取隔离度最大的天线，还可以在蜂窝天线集合中选取其它天线作为最终选取的目标天线，例如，当隔离度最大的天线被遮挡或业务繁忙，可以选取隔离度稍差的其它天线。以图4(a)中的 手机401为例，候选目标天线可以为Ant1和Ant2，如果Ant1被遮挡，则可以选取Ant2作为目标天线。又例如，当WIFI信号的发射功率属于第四发射功率值范围时，可以进一步增加候选目标天线，以图4(a)中的手机401为例，候选目标天线可以为Ant1、Ant2和Ant3，如果Ant3处于关闭状态，可以选择Ant3作为目标天线。第一发射功率值范围中的发射功率值大于第二发射功率值范围中的发射功率值，第二发射功率值范围中的发射功率值大于第三发射功率值范围中的发射功率值，且第三发射功率值范围中的发射功率值大于第四发射功率值范围中的发射功率值。可以理解的是，不同的发射功率值区间还可以对应其它的目标天线选取方式，发射功率区间也还可以有其它划分方式，只要使干扰在可接收范围即可。当有多个候选目标天线时，可以同时根据天线间隔离度、遮挡状态、是否处于关闭状态等因素中的一种或多种因素在蜂窝天线集合中选取一个或多个天线作为目标天线，选取目标天线的过程如前所述。
以判断蓝牙的发射功率为例，根据蓝牙的发射功率选择目标天线时，过程与上述实施例类似，此处不再赘述。
作为另一个实施例，当WIFI是双频工作机制时，即WIFI和蓝牙共用2.4GHz到2.48GHz的频段的天线，同时存在WIFI 5G频段的天线，在WIFI和蓝牙共用天线存在冲突时，可以使WIFI信号独自在5G天线上传输，蓝牙信号独占2.4GHz的频段的天线。
S1052.执行天线切换动作，将蓝牙或WIFI信号切换到目标天线。
图9中，可以在执行S1051后接着执行S1052。作为另一个实施例，可以不执行S1051，直接执行S1052，即，电子设备在判断蓝牙业务和WIFI业务冲突后，将WIFI信号或蓝牙信号直接切换到预设的目标天线上，预设的目标天线为如下天线之一：蜂窝天线集合中与共享天线中任意一个天线隔离度最大的天线、距离最大的天线、隔离度满足要求的天线、与共享天线中的任意一个天线呈对角线分布的天线。
图11是WIFI、蓝牙和蜂窝通过开关阵列切换天线的示意图。在图11中，WIFI模块，蓝牙模块，蜂窝模块通过射频开关阵列(Switch Matrix)连接到可用的天线上(图示为六根)，通过射频开关阵列执行通路切换。
图12(a)、图12(b)和图12(c)示出了切换前后的天线分布变化。如图12(a)所示，初始状态下，WIFI信号和蓝牙信号共享一根天线Ant5，蜂窝信号占用Ant1到Ant4，电子设备判断WIFI和蓝牙业务繁忙且蜂窝业务相对空闲时，从蜂窝天线中挪出一根天线Ant4给蓝牙业务，WIFI业务独占天线Ant4，蜂窝天线的工作模式由4×4MIMO降低到3×3MIMO。在如图12(b)的另一实施例中，当初始状态下蓝牙信号和WIFI信号在两根天线Ant5和Ant6上时分复用时，目标切换天线为Ant3和Ant4，也就是将两路蓝牙信号均切换到蜂窝天线Ant3和Ant4。切换后蓝牙和WIFI均支持2×2MIMO的工作模式，而蜂窝天线的工作模式从4×4MIMO降低到2×2MIMO。如图12(c)所示，蓝牙和WIFI共用两根天线，均支持2×2MIMO的规格。在WIFI和蓝牙共存冲突时，电子设备挪出一根蜂窝天线给蓝牙。蜂窝天线的工作模式从4×4MIMO降低到3×3MIMO,蓝牙天线的工作模式从2×2MIMO降低到1×1MIMO。
作为一个实施例，在执行S1052之前，WIFI业务的时延为第一时延，WIFI业务的速率为第一速率，所述执行S1052之后，WIFI业务的时延为第二时延，WIFI业务的速率为第二速率。第一时延大于第二时延，第一速率小于第二速率。
图13示出了在电子设备内部器件中执行上述步骤S101-S105的原理图。S101-104以及S1051可以在电子设备的应用处理器(Application processor,简称AP)中执行.S1052的执行天线切换动作在AP、蜂窝控制电路、蓝牙WIFI控制电路、开关阵列的交互中执行。蜂窝控制电路 可以是调制解调器或射频集成电路RFIC，也可以包括蜂窝前端模组。蓝牙WIFI控制电路包括蓝牙控制电路和WIFI控制电路，分别用于产生蓝牙信号和WIFI信号。蜂窝控制电路、蓝牙控制电路和WIFI控制电路可以属于一个芯片，也可以属于不同芯片。这里以蓝牙控制电路和WIFI控制电路在一个芯片为例。开关阵列可以为本方案涉及的所有开关，在电路中的位置不做限定。在执行S101-104以及S1051后，执行S1052的执行天线切换动作.S1052可以以下述流程为例：
S1.AP指示蜂窝控制电路停止在目标天线上传输蜂窝信号。
S2.蜂窝控制电路指示开关阵列接通目标天线到蓝牙WIFI控制电路的通路。
S3.AP指示蓝牙WIFI控制电路切换到蓝牙独立传输模式，由此，蓝牙WIFI控制电路将内部软件、硬件和算法等配置更改为蓝牙独立传输模式。
S4.蓝牙WIFI控制电路指示开关阵列导通目标信号到目标天线的通路。目标信号可以为蓝牙信号或WIFI信号。例如，如果将蓝牙信号切换到目标天线，则开关阵列改变导通方向，将蓝牙WIFI控制电路产生的蓝牙信号接通到目标天线。可以理解的是，在S2和S4中，开关阵列也可以由AP进行控制。
电子设备执行S1-S4的天线切换动作时内部器件之间的通路切换过程可以是图14a和图14b的实施例，电子设备的各个内部器件在天线切换前的初始状态如图14a。在图14a中，电子设备200包括蓝牙WIFI控制电路1、蜂窝控制电路2、前端模组3、滤波器4，开关51、开关52、开关53、天线61、天线62、天线63。开关53的作用相当于图5中的开关53，用于初始状态下蓝牙信号和WIFI信号对天线63进行时分复用。开关53可以在前端模组3内，也可以在前端模组3外。天线61可以为一根或多根未被选为目标天线的蜂窝天线。
通过图14(a)的开关51、开关52导通方向可以看出，在初始状态，蜂窝芯片通过天线61和天线62传输蜂窝信号，蓝牙信号和WIFI信号通过开关53时分复用天线63。若天线62为步骤1051中确定的目标天线，且切换的目标信号是蓝牙信号，可执行图13中S1-S4的步骤。在执行S2时，开关51接通到滤波器4以及蓝牙WIFI芯片1的通路，断开与蜂窝控制电路2的通路。在执行S4时，开关52导通到天线62的通路，断开到天线63的通路。开关53停止时分复用切换。由此，电子设备内部的状态由图14(a)切换到图14(b)。又例如，还可以先切换开关52，再切换开关51，或同时控制开关51和52。通过上述步骤，蓝牙WIFI芯片输出的蓝牙信号从天线63切换到蜂窝的天线62进行传输。
作为另一个实施例，在执行天线切换动作后，蜂窝天线还可以继续使用目标天线进行传输，即，如果将蓝牙信号切换到蜂窝天线，则蓝牙信号和蜂窝信号时分复用目标天线；或如果将WIFI信号切换到蜂窝天线，则WIFI信号和蜂窝信号时分复用目标天线。可以理解地，可以通过开关51对天线62进行分时复用。
作为一个实施例，对于图4中的手机401，可以仅将Ant4上的WIFI信号切换到Ant1，并在切换后将Ant5上的WIFI信号的发射功率降低。可以理解的是，当干扰允许时，未进行切换的WIFI信号的发射功率也可以保持不变。
作为另外一个实施例，可以执行在S105之前、判断WIFI和蓝牙业务冲突之后为SIM卡重新调整蜂窝天线的分配，具体策略可以参考表1所示。如果电子设备选择执行可选的S1051，而不是提前预设目标天线，则SIM卡的蜂窝天线分配还可以在执行S1052前、S1051之后进行上述调整。
表1单SIM设备在不同场景下的蜂窝天线分配策略
  主集天线 分集天线 MIMO天线1 MIMO天线2
状态1 SIM SIM SIM SIM
状态2 蓝牙/WIFI SIM SIM SIM
状态3 SIM 蓝牙/WIFI SIM SIM
如表1所示，电子设备为单SIM卡设备。在原始状态(即状态1)下，SIM卡在主集天线、分集天线、MIMO天线1和MIMO天线2中进行通信。作为一个示例，主集天线、分集天线、MIMO天线1和MIMO天线2可以对应于图4(a)中的手机401上的Ant1、Ant2、Ant3和Ant6。
参照状态2，当蓝牙信号或WIFI信号占用的天线为主集天线时，蜂窝信号继续采用分集天线和两根MIMO天线进行通信。可选的，蜂窝信号可以将原先的分集天线调整为主集天线。例如，电子设备的天线系统可以包括主集射频模块和分集射频模块。当某一天线通过双刀双掷开关和主集射频模块连接时，该天线为主集天线；当某一天线通过该双刀双掷开关和分集射频模块连接时，该天线为分集天线。将分集天线调整为主集天线可以包括通过该双刀双掷开关，将主集射频模块和原先的分集天线连接，从而则将分集天线调整为主集天线。通过以上调整，可以尽可能保证单SIM卡设备在天线被抢占后的蜂窝收发性能。
作为另一个实施例，参照表1中的状态3，蓝牙信号或WIFI信号可以占用分集天线。SIM卡继续使用主集天线、MIMO天线1、MIMO天线2。
当电子设备是双SIM卡设备时，参照表2所示，在初始状态(即状态1时)下，主SIM卡占用主集天线和第一MIMO天线，副SIM卡占用分集天线和第二MIMO天线。可以执行在S105之前、确定WIFI业务和蓝牙业务冲突之后为SIM卡重新调整蜂窝天线的分配，具体策略可以参考表1所示。如果电子设备选择执行可选的步骤S1051，而不是提前预设目标天线，则SIM卡的蜂窝天线分配还可以在执行S1052前、S1051之后进行上述调整。
如果蓝牙或WIFI抢占了蜂窝天线，为了保证主副卡的蜂窝通信质量，需要重新调整主卡和副卡的天线占用配置。例如，如果主卡的主集天线被占用，则主卡可能只剩一根MIMO天线可以使用，而MIMO天线相对于主集天线和分集天线性能较弱，导致主卡的通信质量降低，因此可以重新优化主副卡的天线资源配置。例如，在状态2中，当蓝牙或WIFI占用主集天线时，电子设备调整蜂窝主卡的信号占用分集天线和MIMO天线2，副卡信号占用MIMO天线1。可以理解的是，蜂窝主卡还可以切换到分集天线和MIMO天线1，副卡切换到MIMO天线2。可选的，在主集天线被蓝牙或WIFI占用后，电子设备可以将分集天线相应调整为主卡的主集天线。
在状态3中，蓝牙或者WIFI占用主集天线和分集天线。电子设备调整蜂窝主卡占用MIMO天线1，副卡占用MIMO天线2。
在状态4中，蜂窝业务主动回退到单天线状态，主卡和副卡分别占用主集天线和分集天线，此时MIMO天线1和MIMO天线2空闲，可以分配给蓝牙或者WIFI业务，提升蓝牙和WIFI的通信体验。
在状态5中，使蜂窝和蓝牙、或者蜂窝和WIFI业务进行时分复用，最大化系统资源的利用率。例如，主卡和蓝牙时分复用主集和MIMO天线1，副卡和WIFI时分复用分集和MIMO天线2。

在WIFI信号或蓝牙信号占用了蜂窝天线的情况下，当WiFi信号和蓝牙信号的共存情况发生变化或者蜂窝上发起了数据业务或者通话业务，需要进行天线切换策略的回退。在本申请的一个实施例中，天线切换回退的方法流程如图15(a)所示：
S1301和S1302实时统计WIFI通道和蓝牙通道的业务指标，包括数据吞吐量、信道占用率、业务时延和体验质量(Qurlity of Experience,QoE)等指标。
S1303判断WIFI业务和蓝牙业务的冲突是否解除。判断方法和S103类似，此处不再赘述。
S1304实时统计蜂窝的业务指标。
S1305如果蜂窝业务的业务指标统计结果是否大于第四统计结果阈值，则确定蜂窝存在高优先级业务，例如可以是数据业务、通话业务等。一个可能的场景是，WIFI信道质量不佳时，可以开启蜂窝和WIFI同时传输模式，此时蜂窝信道忙，另一个可能的场景是，蜂窝突发来电或拨话。
S1306判断传输蜂窝信号的天线和目标天线中的至少一个天线信号强度是否小于第一信号强度阈值；例如某一天线被遮挡时或用户进入蜂窝覆盖较差区域可能某个天线的信号强度低于该第一信号强度阈值，进而通信质量较差。如果目标天线被遮挡，则可以取消时分复用。如果其余蜂窝天线被遮挡，则蜂窝需要更多天线传输数据，也可以取消时分复用。
可以理解的是，如果处理器的性能支持，上述步骤可以同时进行。上述步骤不限执行顺序。
如果S1303、S1305、S1306中至少一个满足条件，则执行S1307,否则继续执行S1301、S1302、S1304和S1306。
S1307结束蜂窝天线的切换状态。结束蜂窝天线的切换状态为退回到执行S108之前的蓝牙信号、WIFI信号和蜂窝信号的天线占用状态。目标天线上停止传输蓝牙信号或WIFI信号，并重新用于传输蜂窝信号，且蓝牙信号和WIFI信号重新占用共享天线。
在图15(b)中，作为另一个实施例，将S1301和S1302替换为S1301’。
S1301’实时检测业务场景是否发生变化。
当检测到业务场景发生变化的时候，比如前台应用识别到退出游戏应用，结束视频通话等用户操作，发出场景结束的通知给应用处理器。应用处理器继续执行S1303的步骤，判断WIFI和蓝牙业务的冲突解除。
本申请实施例还提供一种芯片系统，如图16所示，该芯片系统包括至少一个处理器1601和至少一个接口电路1602。处理器1601和接口电路1602可通过线路互联。例如，接口电路1602可用于从其它装置(例如中心设备的存储器)接收信号。又例如，接口电路1602可用于向其它装置(例如处理器1601)发送信号。示例性的，接口电路1602可读取存储器中存储的指令，并将该指令发送给处理器1601。当所述指令被处理器1601执行时，可使得电子设备(如图1所示的电子设备100)执行上述实施例中的各个步骤。当然，该芯片系统还可以包含其他分立器件，本申请实施例对此不作具体限定。
