Description

一种通话切换方法、终端设备及存储介质 技术领域
本发明涉及通信技术领域，尤其涉及一种通话切换方法、终端设备及存储介质。
背景技术
随着通信技术的不断发展，使得随时随地通话已不成问题。当前，语音通话通常都是与客户识别模块(英文：Subscriber Identity Module，简称：SIM)卡绑定的，同时由运营商提供语音通话业务。通常情况下，通话过程都是使用特定的网络，例如中国移动通信公司以及中国联合网络通信集团有限公司使用全球移动通信系统(英文：Global System for Mobile Communication，简称：GSM)提供语音通话业务。而中国电信集团公司使用码分多址(英文：Code Division Multiple Access，简称：CDMA)技术提供语音通话业务。在业界内，传统的语音通话技术称为电路交换(英文：Circuit Switched，简称：CS)域语音。
然而，上述传统的语音通话因为比较单一而且资费较高，所以又发展出了其它多种通话网络，例如通过无线保真(英文：Wireless Fidelity，简称：WiFi)达成的无线局域网的通话方式，业界内称为WiFi Call。再例如基于长期演进(英文：Long Term Evolution，简称：LTE)系统的通话技术，业界内称为VoLTE(Voice over LTE)或者称为网络协议多媒体子系统(英文：IP Multimedia Subsystem，简称：IMS)Call。
在实际使用中，用户可以选择其中一种通话网络进行通话，所以用户可以有较多的选择。
发明内容

图2为本发明实施例提供的第一种通话切换方法的流程图，请参考图2所示，为本发明实施例提供的一种通话切换方法的流程图。如图2所示，该方法包括：
步骤101：当第一终端设备检测到用户输入的向第二终端设备发起通话请求的输入操作时，或者当第一终端设备接收到第二终端设备通过第二类型的通信网络发起的第一通话请求时，第一终端设备检测所述第一终端设备与第二终端设备是否同时处于第一类型的通信网络；
步骤102：当第一终端设备检测到第一终端设备和第二终端设备同时处于第一类型的通信网络时，第一终端设备通过第一类型的通信网络向第二终端设备发起第二通话请求；其中，第一类型的通信网络和第二类型的通信网络不同。
在实际运用中，第一终端设备可能是主叫设备，对应的，第二终端设备为被叫设备。反之，第一终端设备也可以是被叫设备，相应的，第二终端设备为主叫设备。
当第一终端设备为主叫设备时，在步骤101之前，该方法还包括：第一终端设备检测是否有用户输入的向第二终端设备发起通话请求的输入操作。可选的，该输入操作是需要通过第二类型的通信网络向第二终端设备发起呼叫请求的输入操作。举例来说，用户选中第二终端对应的手机号，并点击了拨号键，此时，第一终端设备可以检测到该拨号操作。当然，也可以是在第二类型的通信网络，例如WiFi的通话界面，用户输入了拨号操作，此时第一终端设备也可以检测到拨号操作。
当第一终端设备为被叫设备时，在步骤101之前，该方法还包括：第一终端设备接收所述第二终端设备发起的所述第一通话请求。
可选的，第二类型的通信网络例如为GSM或者CDMA(也可以称为2G网络)，对应的，第一通话请求为通过GSM或者CDMA对应的移动通信模块来发起的或者接收的。
可选的，第一类型的通信网络例如为LTE系统(也可以称为4G网络)或者WiFi网络。
在实际运用中，步骤101可以有多种实施方式，其中一种实施方式为：第一终端设备确定所述第一终端设备处于第一类型的通信网络；第一终端设备向服务器发送查询请求，所述查询请求用于查询第二终端设备当前所连接的通信网络的网络类型；其中，服务器中记录有第二终端设备当前所连接的通信网络的网络类型；第一终端设备接收服务器发送的查询结果；所述查询结果包括第二终端设备当前所连接的通信网络的网络类型；第一终端设备根据所述查询结果检测所述第一终端设备与第二终端设备是否同时处于第一类型的通信网络。
详细来说，可以在现有的网络中增设服务器，终端设备可以周期性上报或者在所连接的通信网络的网络类型发生变化时上报所述第一终端设备所连接的通信网络的网络类型。进一步，还可以上报网络的信号质量。服务器保存并更新每个终端设备当前所连接的通信网络的网络类型，进一步还保存该通信网络的信号质量。因此，第一终端设备可以向服务器发送用于查询第二终端设备当前所连接的通信网络的网络类型的查询请求。可选的，查询请求中可以包括第二终端设备的设备标识或者第二终端设备在服务器上注册的账号，也可以是手机号。只要该标识、账号或手机号是唯一的即可。设备标识例如为国际移动设备标识(英文：International Mobile Equipment Identity，简称：IMEI)，或者是移动设备标识码(英文：Mobile Equipment Identifier，简称：MEID)。设备标识、手机号或者账号可以统称为终端设备的唯一识别码。
服务器在接收到第一终端设备发送的查询请求之后，可以根据第二终端 设备的唯一识别码查询到第二终端设备当前所连接的通信网络的网络类型，例如为2G、WiFi或者4G。在查询到之后，服务器将查询结果发送给第一终端设备。相应的，第一终端设备接收该查询结果，并根据所述查询结果检测第二终端设备是否同时处于第一类型的通信网络。
举例来说，假设第一类型的通信网络为WiFi网络，第二类型的通信网络为2G网络。第一终端设备当前所连接的通信网络为2G网络和WiFi。同时，查询结果表明第二终端设备当前所连接的通信网络为2G网络和WiFi网络，所以第一终端设备就可以确定所述第一终端设备和第二终端设备同时处于WiFi网络中。
当第一终端设备为主叫设备时，步骤101的另一种可能的实现方式为：第一终端设备接收第二终端设备发送的第二提示信息，所述第二提示信息中包括第二终端设备当前所连接的通信网络的网络类型；第一终端设备根据所述第一终端设备当前所连接的通信网络的网络类型及所述第二提示信息检测所述第一终端设备与第二终端设备是否同时处于第一类型的通信网络。
可选的，第二终端设备可以以浏览器/服务器模式(英文：Browser/Server，简称：B/S)或者客户端/浏览器模式(英文：Client/Server，简称：C/S)发送提示信息给第一终端设备。当然，在实际运用中，还可以通过其它方式发送提示信息，例如通过短信。
举例来说，当第一终端设备呼叫第二终端设备时，第二终端设备在接收到呼叫请求时，可以将包含所述第一终端设备当前所连接的通信网络的网络类型的提示信息发送给第一终端设备，例如提示信息中包含WiFi网络，第一终端设备进而根据该提示信息中的WiFi网络和所述第一终端设备当前所连接的WiFi确定第一终端设备和第二终端设备同时处于WiFi中。
当第一终端设备为主叫设备时，步骤101的再一种可能的实现方式为：第一终端设备接收第二终端设备发送的第三提示信息，所述第三提示信息用以表征第一终端设备和第二终端设备是否同时处于第一类型的通信网络；第一终端设备根据所述第三提示信息确定第一终端设备和第二终端设备是否同 时处于第一类型的通信网络。
举例来说，第一终端设备呼叫第二终端设备时，第二终端设备在检测到该呼叫请求时，就向服务器查询第一终端设备当前所连接的通信网络的网络类型，然后根据第一终端设备当前所连接的通信网络的网络类型和所述第一终端设备当前所连接的通信网络的网络类型确定第一终端设备和第二终端设备是否同时处于第一类型的通信网络。例如在服务器上的查询结果为第一终端设备当前所连接的通信网络为4G网络，而第二终端设备当前所连接的通信网络为WiFi，所以第二终端设备判断的结果为两者未同时处于第一类型的通信网络。如果在服务器上的查询结果为第一终端设备当前所连接的通信网络也为WiFi，那么第二终端设备判断的结果为两者同时处于WiFi网络，即同时处于第一类型的通信网络。然后第二终端设备将自己的判断结果，即提示信息发送给第一终端设备。
当在步骤101中检测的结果为第一终端设备和第二终端设备同时处于第一类型的通信网络时，接下来执行步骤102，通过第一类型的通信网络向第二终端设备发起第二通话请求。
进一步，如果检测到第一终端设备第一终端设备和第二终端设备同时处于第一类型的通信网络时，第一终端设备还放弃第一终端设备和第二终端设备通过第二类型的通信网络发起的第一通话请求。其中，放弃第一通话请求即为拒绝或者挂断当前通话请求。
举例来说，当第一用户在第一终端设备上拨打手机号139xxxxxxxx时，此时，第一终端设备执行步骤101。在步骤101中的检测的结果为第一终端设备和第二终端设备均处于WiFi时，第一终端设备发起WiFi通话请求。
再举例来说，当第一终端设备接收到手机号为139xxxxxxxx的第二终端打来的电话时，第一终端设备执行步骤101。在步骤101中的检测的结果为第一终端设备和第二终端设备均处于WiFi时，第一终端设备挂断该电话并发起WiFi的通话请求。
可选的，可以在输出模块60包含的显示器上显示通话界面。
可选的，如果在步骤101中检测的结果为第一终端设备和第二终端设备未同时处于第一类型的通信网络时，就通过第二类型的通信网络向第二终端发起第三通话请求。
需要说明的是，WiFi通话可以是手机号也可以是其它的ID，如果是运营商的WiFi网络，一般是通过手机号进行通信。如果是非运营商的WiFi网络，通常会用一个其它的ID来表示用户的身份，该ID在全网中是唯一的，例如前述的设备标识或者账号。而用户的身份ID都是在网络服务器上，无论是运营商还是非运营商都存在一种心跳的机制，终端设备会以一定的频率通知网络服务器所述第一终端设备在网的状态，所以可以准确的进行通话网络的切换，而不会出现切换后通话两端不一样的情况。
在一种可能的实现方式中，第一终端设备具有第一账户和第二账户；所述第二终端具有第三账户和第四账户。第一账户和所述第二账户关联；所述第三账户和所述第四账户关联。第一账户与第三账户可以通过所述第二类型的通信网络建立通话请求。第二账户与第四账户可以通过所述第一类型的通信网络建立通话请求。例如，第一账户和第二账户为手机号码，第三账户为第一终端设备的唯一识别码，第四账户为第二终端设备的唯一识别码。
由以上描述可以看出，本发明实施例中的方法通过终端设备自动判断通话双方所连接的通信网络的网络类型，进而自动选择通话网络，相较于现有技术中的人工选择通话网络，本发明实施例中的方法具有更加灵活的技术效果。举例来说，用户可以设置第一类型的通信网络为WiFi网络，第二类型的通信网络为2G网络。因为2G网络的通话资费较高，而WiFi网络通常为免费网络或者资费较低，所以当检测到用户在拨打2G电话时，就检测是否通话两端均处于WiFi网络，如果是的话，就切换为WiFi网络，如此可以灵活在不同的通话网络之间切换，以达到降低费用的效果。
进一步，为了保证在第一类型的通信网络中的通话质量，在步骤102之前，该方法还包括：第一终端设备确定第一类型的通信网络的信号质量满足预设条件。其中，信号质量可以用多种参数表征，例如带宽、数据传输速率、 信噪比、丢包率、信号强度。如果信号质量是带宽的话，第一终端设备就确定第一类型的通信网络的带宽是否大于或等于预设带宽。如果信号质量是数据传输速率的话，第一终端设备就确定当前的数据传输速率是否大于或等于预设的传输速率，如果信号质量是信噪比的话，第一终端设备就确定当前的信噪比是否大于或等于预设的信噪比，如果信号质量是信号强度的话，第一终端设备就确定当前的信号强度是否大于或等于预设的信噪比。因此，根据不同的参数，预设条件也会不同。
通过该方法，尽可能的保证通话质量，满足用户的体验度，所以用户的体验较好。
需要说明的是，第一终端设备获取通信网络的信号质量根据网络类型的不同，也会不同，不过不管是哪种网络，获取信号质量为本领域技术人员所熟知的内容，例如获取WiFi网络的信号质量，可以是获取WiFi的信号强度和带宽可以计算出网络传输速率，所以在此不再赘述。
另外需要说明的是，确定第一类型的通信网络的信号质量满足预设条件包括：确定所述第一终端设备侧的第一类型的通信网络的信号质量和/或第二终端设备侧的第一类型的通信网络的信号质量满足预设条件。
关于确定第二终端设备侧的第一类型的通信网络的信号质量满足预设条件，在前文中描述了各终端设备在向服务器上报所连接的通信网络的类型时，还可以上报该通信网络的信号质量，所以第一终端设备可以单独向服务器请求第二终端设备侧所连接的第一类型的通信网络的信号质量，也可以是服务器将信号质量携带在检测结果中下发给第一终端设备。
当第一终端设备作为被叫设备时，除了可以按照前述描述的方法实施外，还可以采用如下实施方式；
图3为本发明实施例提供的第二种通话切换方法的流程图，请参考图3所示，该方法包括：
步骤201：第一终端设备接收第二终端设备通过第二类型的通信网络发起的第一通话请求；
步骤202：第一终端设备检测所述第一终端设备与第二终端设备是否同时处于第一类型的通信网络；
步骤203：在第一终端设备和第二终端设备同时处于第一类型的通信网络时，第一终端设备放弃所述第一通话请求，并向第二终端设备发送第一提示信息；其中，所述第一提示信息用于表征第一终端设备和第二终端设备同时处于第一类型的通信网络；第一类型的通信网络和第二类型的通信网络不同。
其中，步骤201和步骤202以及步骤203中放弃第一通话请求的部分与前述描述的相同或类似，所以在此不再赘述。
由以上描述可以看出，在本发明实施例中，第一终端设备自动检测通话两端设备的网络情况，并将可以切换通话网络的提示信息发给对端终端设备，使得对端终端设备可以直接基于该提示进行通话网络的切换，省去了对端终端设备检测网络的步骤，节约了切换的时间。
需要说明的是，步骤203中，第一终端设备向第二终端设备发送用于表征第一终端设备和第二终端设备同时处于第一类型的通信网络的提示信息，例如可以以B/S模式或者C/S模式发送该提示信息。
而第二终端设备在接收到该提示信息之后，可以直接发起第一类型的通信网络上的呼叫请求。
虽然上述描述了第一终端设备作为被叫的情况，但是图2所示的方法同样适用于第一终端设备为主叫的情况，例如在检测到前述的输入操作时，也可以执行步骤202至步骤203。
换言之，在本实施例中，被叫设备在检测到被叫设备和主叫设备同时处于第一类型的通信网络中时，会主动挂断接收到的通话请求，但是可以不主动发起第一类型的通信网络的通话请求，而是将检测结果发送给主叫设备。主叫设备可以基于检测结果确定是否发起第一类型的通信网络的通话请求。
类似的，为了保证通话质量，在步骤202之后，步骤203之前，该方法还包括：第一终端设备确定第一类型的通信网络的信号质量满足预设条件。该步骤的具体实施方式可以参考前述描述的内容。
在图2及图3的通话切换方法中，通话请求可以是语音通话请求，也可以是视频通话请求。如果是视频通话请求时，第一类型的通信网络可以是WiFi网络，第二类型的通信网络可以是4G网络。
另外，需要说明的是，本文中第一类型的通信网络和第二类型的通信网络还可以是未来5G网络或者其它网络，只要是可以实现语音通话或者视频通话的通信网络，均适用于本发明实施例中的方法。
以上描述了终端设备可以自动选择或者切换语音通话或视频通话的网络，接下来将描述在视频通话中，可以根据通信网络的信号质量选择在不同网络上或者在同一网络上传输视频通话的语音数据和图像数据。以下将详细描述这部分内容；
图4为本发明实施例提供的第三种通话切换方法的流程图，请参考图4所示，为本发明实施例提供的另一种通话切换方法的流程图。该方法包括：
步骤301：在第一终端设备和第二终端设备通过第一类型的通信网络进行视频通话时，第一终端设备确定第一类型的通信网络的信号质量是否满足预设条件；
步骤302：在所述第一类型的通信网络的信号质量不满足所述预设条件时，第一终端设备通过第二类型的通信网络向第二终端设备发起语音通话请求；
步骤303：在所述语音通话请求被应答之后，第一终端设备通过第二类型的通信网络发送以及接收所述视频通话的音频数据；并通过第一类型的通信网络发送以及接收所述视频通话的图像数据；其中，第一类型的通信网络和第二类型的通信网络不同。
在实际运用中，该视频通话可以是第一终端设备发起的，也可以是第二终端设备发起的。
步骤301中，第一终端设备确定第一类型的通信网络的信号质量是否满足预设条件，具体的实施过程与前述描述的实施过程类似，所以在此不再赘述。
在第一类型的信号质量不满足预设条件时，表示第一类型的通信网络当前的通信质量不是很好，所以第一终端设备通过第二类型的通信网络向第二终端设备发起语音通话请求。在语音通话请求被应答之后，就可以通过第一类型的通信网络收发视频通话的图像数据；以及通过第二类型的通信网络收发视频通话的音频数据。由此实现音频数据和图像数据分离在不同的网络上传输的目的，进而可以尽可能的保证语音的通话质量和图像的传输质量。
举例来说，第一终端设备和第二终端设备通过4G网络在进行视频通话，此时，视频通话的音频数据和图像数据均是通过4G网络传输的。第一终端设备检测4G网络的信号质量是否较好，如果检测的结果为4G网络的信号质量不是很好，例如信号强度较弱，传输速率较低，导致的结果可能的是视频通话出现卡顿的情况。因此，此时，第一终端设备向第二终端设备发起2G的语音通话，在第二终端设备应答了该语音通话请求之后，第一终端设备和第二终端设备就可以通过2G网络传输音频数据，然后通过4G网络传输图像数据。换言之，通过两种网络实现视频通话，以保证通信质量。
可选的，在步骤103之后，该方法还包括：第一终端设备确定所述第一类型的通信网络的信号质量是否满足所述预设条件；在所述第一类型的通信网络的信号质量满足所述预设条件时，第一终端设备放弃通过第二类型的通信网络发起的语音通话，并通过第一类型的通信网络发送与接收所述视频通话的音频数据与图像数据。
继续以前述例子为例进行说明。在通过2G网络传输音频数据以及通过4G网络传输图像之后，第一终端设备还可以实时检测4G网络的信号质量是否变好，在信号质量变好之后，就可以挂断2G的语音通话，继续通过4G网络传输语音和图像。
可选的，可以将音频数据加入在图像数据中，例如采用动态图像专家组(英文：Moving Picture Experts Group，简称：MPEG)-4压缩编码标准对音频数据和图像数据进行压缩编码，然后将压缩后的音视频数据通过4G网络进行传输。在实际运用中，还可以采用其它的压缩编码标准将音频数据加入在 图像数据中，例如H.246、音频视频交错格式(英文：Audio Video Interleaved，简称：AVI)等，该部分内容为本领域技术人员所熟知的内容，所以在此不再赘述。
上述描述了在视频通话中，根据视频通话的承载网络的信号质量对视频通话的音频数据和图像数据进行分离传输的过程，接下来将描述一个在语音通话的过程中发起视频通话时的通话切换方法；
图5为本发明实施例提供的第四种通话切换方法的流程图，请参考图5所示，该方法包括：
步骤401：在第一终端设备和第二终端设备通过第二类型的通信网络进行语音通话时，第一终端设备通过第一类型的通信网络与所述第二终端设备建立视频通话；
步骤402：第一终端设备确定第一类型的通信网络的信号质量是否满足预设条件；
步骤403：在所述第一类型的通信网络的信号质量不满足所述预设条件时，第一终端设备通过第二类型的通信网络发送以及接收所述视频通话的音频数据；并通过第一类型的通信网络发送以及接收所述视频通话的图像数据；其中，所述第一类型的通信网络和所述第二类型的通信网络不同。
在本实施例中，当第一终端设备和第二终端设备在通过第二类型的通信网络进行语音通话时，例如通过2G网络在进行语音通话时，第一终端设备或者第二终端设备通过第一类型的通信网络发起视频通话的请求，在应答后，第一终端设备以及第二终端设备之间就建立了视频通话，例如通过WiFi建立了视频通话。换言之，在同一时刻，第一终端设备和第二终端上在不同的两个网络上建立有语音通话和视频通话。
此时，第一终端设备可以执行步骤402，即判断第一类型的通信网络的信号质量是否满足预设条件。换言之，即确定第一类型的通信网络的信号质量是否比较好，例如判断WiFi网络的信号质量是否良好。具体的确定方式请参考前述的描述。
在信号质量不满足预设条件，即信号质量不是很好时，就将视频通话的音频数据分离到第二类型的通信网络上进行传输，第一类型的通信网络只传输视频通话的图像数据即可。如此可以尽可能的保证语音和图像的质量。
例如，在WiFi网络的信号质量不是很好时，就通过2G网络传输音频数据，WiFi网络只传输图像数据即可。
可选的，在步骤403或者步骤402之后，该方法还包括：第一终端设备确定所述信号质量是否满足所述预设条件；在所述信号质量满足所述预设条件时，第一终端设备放弃第二类型的通信网络上的语音通话，并通过第一类型的通信网络发送以及接收所述视频通话的音频数据和图像数据。
举例来说，如果检测到WiFi网络的信号质量良好，那么就挂断2G网络的语音通信，并通过WiFi网络传输音频数据和图像数据。如此在保证通话质量的同时，既可以节约2G网络语音通话的资费，也可以为终端设备省电。
由上面对图4和图5所示的通话切换方法的描述可以看出，在这两个实施例中，可以根据视频通话的信号质量来确定是否要将视频通话的音频数据和图像数据分离在不同的两个网络上传输，如此可以保证视频通话的质量。进一步，在视频通话的信号质量转好时，可以再次将音频数据和图像数据进行合成，并通过视频通话的网络传输音频数据和图像数据。如此可以在保证通信质量的情况下，为终端设备省电。
基于同一发明构思，本发明实施例还提供一种终端设备，其结构例如如图1所示，用以实现图2至图4中所示的任意一种通话切换方法，在实际运用中，可以根据实际需求对终端设备进行配置。

前述图2至图4实施例中的通话切换方法中的各种变化方式和具体实例同样适用于本实施例的终端设备，通过前述对通话切换方法的详细描述，本领域技术人员可以清楚的知道本实施例中终端设备的实施方法，所以为了说 明书的简洁，在此不再详述。
基于同一发明构思，本发明实施例还提供一种终端设备，用以实现如图2和图3所示的通话切换方法，如图6所示，该终端设备包括：用户输入单元501，用于检测用户输入的向第二终端设备发起通话请求的输入操作；接收单元502，用于接收所述第二终端设备通过第二类型的通信网络发起的第一通话请求；检测单元503，用于当用户输入单元501检测到所述输入操作时或者接收单元502接收到所述第一通话请求时，检测所述终端设备与第二终端设备是否同时处于第一类型的通信网络；发送单元504，用于根据所述处理单元的指示向所述第二终端设备发送第一提示信息；其中，所述第一提示信息用于表征所述终端设备和所述第二终端设备同时处于所述第一类型的通信网络；处理单元505，用于当检测单元503检测到所述终端设备和所述第二终端设备同时处于所述第一类型的通信网络时，通过所述第一类型的通信网络向所述第二终端设备发起第二通话请求，或者通过发送单元504向所述第二终端设备发送所述第一提示信息；其中，所述第一类型的通信网络和所述第二类型的通信网络不同。
