Description

卫星通话方法和终端设备
本申请要求于2023年6月16日提交国家知识产权局、申请号为202310730467.0、申请名称为“卫星通话方法和终端设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及电子技术领域，具体涉及一种卫星通话方法和终端设备。
背景技术
卫星通信是地球上(包括地面和低层大气中)的无线电通信设备之间利用卫星作为中继而进行的通信。卫星通信具有通信范围大、可靠性高，不易受陆地灾害的影响等优点。因此，若手机等智能终端设备能够实现卫星通信，将会给其发展带来突破性进展。
由于卫星通信的空口链路比较长，路损比较大，因此对于终端设备的空中下载技术(over-the-air technology，OTA)要求比较高。然而，对于智能终端设备来说，天线空间小，天线个体也小，链路预算很紧张。所以，智能终端设备在卫星通信过程中，需要保持对星姿态才能保持业务的连续性。以卫星通信中的语音通话(简称卫星通话)为例，卫星通话过程中，智能终端设备需要保持对星姿态，否则容易通话中断(即通话掉话)。
发明内容
本申请提供了一种卫星通话方法和终端设备，能够防止卫星通话中断，提高用户体验。
第一方面，本申请提供一种卫星通话方法，该方法由终端设备执行，该方法包括：基于与第一卫星的通信，进行卫星通话并显示通话界面；确定方位角偏差和俯仰角偏差，方位角偏差是指终端设备的天线辐射方向的方位角与卫星传输链路方向的方位角之间的偏差，俯仰角偏差是指天线辐射方向的俯仰角与卫星传输链路方向的俯仰角之间的偏差，卫星传输链路方向是指终端设备所处位置至第一卫星所处位置的方向；若方位角偏差和俯仰角偏差满足预设条件，则在通话界面中显示提示信息，提示信息用于提示用户终端设备存在通话终端的可能性。
预设条件用于表征终端设备的方位角偏差和/或俯仰角偏差偏离预设的范围，即终端设备偏离预设的位置范围，终端设备存在对星失败的可能性，从而出现通话中断的可能性。
可选的，提示信息可以以文字、图片、动画等形式显示。例如，提示信息可以为“手机已偏离对星位置，通话可能中断，请尽快调整手机方向”等文字信息。
本申请第一方面提供的卫星通话方法，在卫星通话过程中，通过确定方位角偏差和俯仰角偏差，在方位角偏差和俯仰角偏差满足预设条件时，在通话界面中显示提示信息，提示信息用于提示用户中断设备存在通话中断的可能性，便于用户及时调整手机位置，防止通话中断，提高用户体验。
一种可能的实现方式中，预设条件为：方位角偏差超出第一方位角范围，和/或俯仰角偏差超出第一俯仰角范围。
可选的，第一方位角范围可以与对星时要求的方位角范围相同，第一俯仰角范围可以与对星时要求的俯仰角范围相同。
在一个具体的实施例中，第一方位角范围可以为[-10°，10°]，第一俯仰角范围可以为[-5°，5°]。
该实现方式中，方位角偏差超出第一方位角范围，和/或俯仰角偏差超出第一俯仰角范围，说明方位角偏差和俯仰角偏差中至少一个较大，终端设备当前的位置偏离预设的位置范围，天线的辐射方向与卫星传输链路方向之间的偏差较大，极大可能出现对星失败的情况，因而极大可能出现通话质量下降，通话中断的情况，因此，终端设备在通话界面中显示提示信息，准确地向用户提示该情况，提高用户体验。
一种可能的实现方式中，若方位角偏差和俯仰角偏差满足预设条件，则在通话界面中显示提示信息之前，该方法还包括：获取与第一卫星通信的信号强度；预设条件为：信号强度小于预设阈值，且方位角偏差超出第二方位角范围；或者，预设条件为：信号强度小于预设阈值，且俯仰角偏差超出第二俯仰角范围；或者，预设条件为：信号强度小于预设阈值，且方位角偏差超出第二方位角范围，且俯仰角偏差超出第二俯仰角范围。
可选的，卫星通信的信号强度可以通过接收信号强度指示(received signal strength indicator，RSSI)、参考信号接收功率(reference signal receiving power，RSRP)、参考信号接收质量(reference signal receiving quality，RSRQ)、信号与干扰加噪声比(signal to interference plus noise ratio，SINR)和信噪比(signal to noise ratio，SNR)等中的一项或多项表征。
卫星通信的信号强度小于预设阈值，说明信号强度弱，当前卫星通信质量下降，可能出现通话中断的情况。方位角偏差超出第二方位角范围，和/或俯仰角偏差超出第二俯仰角范围，说明方位角偏差和俯仰角偏差中至少一个较大，终端设备当前的位置偏离预设的位置范围，天线的辐射方向与卫星传输链路方向之间的偏差较大，极大可能出现对星失败的情况，进一步说明终端设备极大可能出现通话质量下降，通话中断的情况。
该实现方式中，在方位偏差和俯仰角偏差的基础上，进一步增加卫星通信的信号强度，将信号强度也作为判断终端设备偏离预设位置范围的必要条件，进一步提高判断的准确性，因此，能够更准确的在通话界面中显示提示信息，准确地向用户提示该情况。
可选的，第二方位角范围大于第一方位角范围，和/或，第二俯仰角范围大于第一俯仰角范围。也即，将判断方位角偏差和俯仰角偏差情况的条件放宽，这样，将放宽后的方位角偏差和俯仰角偏差，与卫星通信的信号强度一起作为判断条件，判断当前通话质量情况，提高判断结果准确度的同时，能够防止判断条件过于苛刻，从而防止过于频繁的显示提示信息而打扰用户，进一步提高用户体验。
一种可能的实现方式中，通话界面中包括对星指示信息，对星指示信息用于指示终端设备与第一卫星的对准情况。
可选的，对星指示信息可以以文字、图片、动画等形式显示。
一种可能的实现方式中，对星指示信息根据方位角偏差和俯仰角偏差确定。
该实现方式中，终端设备根据方位角偏差和俯仰角，在通话界面中显示对星指示信息。如此，用户能够在卫星通话过程中，随时获知终端设备的对星情况，防止因用户移动终端设备位置导致对星失败，进一步防止通话中断，提高用户体验。
第二方面，本申请提供一种卫星通话方法，该方法由终端设备执行，该方法包括：基于与第一卫星的通信，进行卫星通话，卫星通话的通话模式为除听筒模式之外的模式；显 示通话界面；通话界面中不包括听筒模式的切换控件，或者，通话界面中包括听筒模式的切换控件但终端设备屏蔽对第一操作的响应，第一操作为用户点击听筒模式的切换控件的操作，听筒模式的切换控件用于将通话模式切换为听筒模式。
也就是说，该方法中，卫星通话过程中，通话模式为非听筒模式。可选的，卫星通话模式可以为第一模式、第二模式和免提模式。其中，第一模式也称为有线音频设备模式，为通过与终端设备有线连接的音频设备通话的模式。第二模式也称为无线音频设备模式，为通过与终端设备无线连接的音频设备通话的模式。其中，无线连接可以为蓝牙连接、无线局域网(wireless local area networks，WLAN)、无线保真(wireless fidelity，Wi-Fi)等。音频设备可以为音箱、耳机、车载设备等。免提模式为通过终端设备自身的扬声器和麦克风等通话的模式。听筒模式为通过终端设备自身的受话器和麦克风等通话的模式。
第二方面提供的卫星通话方法，通话模式为非听筒模式，且在通话界面中不显示听筒模式的切换控件，或者显示听筒模式的切换控件，但是将该切换控件的功能屏蔽，使其不可操作。如此，在卫星通话过程中，用户不可使用听筒模式进行通话，一方面能够降低卫星通话过程中辐射对用户头部的影响，提高用户体验；另一方面能够防止用户因使用听筒模式而随意移动终端设备的位置，防止终端设备偏离对星位置，进而防止通话中断，进一步提高用户体验。
一种可能的实现方式中，该方法还包括：若存在与终端设备有线连接的第一音频设备，则确定通话模式为第一模式，第一模式为通过第一音频设备通话的模式。

一种可能的实现方式中，该方法还包括：若存在与终端设备有线连接的第一音频设备，且存在与终端设备无线连接的第二音频设备，则通话界面中包括第一控件；响应于用户点击第一控件，显示免提模式的切换控件和第二模式的切换控件，免提模式的切换控件用于将通话模式切换为免提模式，第二模式为通过第二音频设备通话的模式，第二模式的切换 控件用于将通话模式切换为第二模式。
该实现方式中，用户可以通过点击第一控件触发免提模式的切换控件和第二模式的切换控件的显示，而在用户无需切换通话模式时，仅显示第一控件，如此，便于界面中控件的排布和显示，提高用户体验。
一种可能的实现方式中，该方法还包括：若存在与终端设备无线连接的第二音频设备，且不存在与终端设备有线连接的音频设备，则确定通话模式为第二模式，第二模式为通过第二音频设备通话的模式。
该实现方式中，在存在与终端设备无线连接的音频设备，且不存在与终端设备有线连接的音频设备时，将通话模式设置为无线音频设备模式，如此延续用户对音频设备的使用需求，更符合用户的使用习惯和使用场景，提高用户体验。
一种可能的实现方式中，通话界面中包括免提模式的切换控件，免提模式的切换控件用于将通话模式切换为免提模式。

具体实施方式
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描述。其中，在本申请实施例的描述中，除非另有说明，“/”表示或的意思，例如，A/B可以表示A或B；本文中的“和/或”仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，在本申请实施例的描述中，“多个”是指两个或多于两个。
以下，术语“第一”、“第二”、“第三”仅用于描述目的，而不能理解为指示或暗示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”、“第三”的特征可以明示或者隐含地包括一个或者更多个该特征。
在本申请说明书中描述的参考“一个实施例”或“一些实施例”等意味着在本申请的 一个或多个实施例中包括结合该实施例描述的特定特征、结构或特点。由此，在本申请说明书中的不同之处出现的语句“在一个实施例中”、“在一些实施例中”、“在其他一些实施例中”、“在另外一些实施例中”等不是必然都参考相同的实施例，而是意味着“一个或多个但不是所有的实施例”，除非是以其他方式另外特别强调。术语“包括”、“包含”、“具有”及它们的变形都意味着“包括但不限于”，除非是以其他方式另外特别强调。
为更好地理解本申请实施例，以下对实施例中可能涉及的术语或概念进行解释说明。
卫星通信：利用人造地球卫星作为中继站来转发无线电波，从而实现两个或多个地球站之间的通信。
空中下载技术：是一种通过移动通信的空中接口对电子设备中的数据及应用进行远程管理的技术。
路损：路径损耗，或称传播损耗，指电波在空间传播所产生的损耗。路损是由发射功率的辐射扩散及信道的传播特性造成的，反映宏观范围内接收信号功率均值的变化。
链路预算(link budget)：是在一个通信系统中对发送端、通信链路、传播环境(大气、同轴电缆、波导、光纤等)和接收端中所有增益和衰减的核算。其通常用来估算信号能成功从发射端传送到接收端之间的最远距离。
对星：配对、成双成对的意思。终端设备对星，或称为天线对星，是指调整天线的方位角、俯仰角等，使天线辐射方向对准卫星的过程。其中，天线辐射方向可以为天线波束的中心方向。
智能终端设备(简称终端设备)由于天线空间和天线个体均较小，因此链路预算紧张，在卫星通信过程中，需要保持对星的姿态，否则容易通信中断。以卫星通话来说，用户在对星完成后，需要尽量保持智能终端处于对星后的姿态，若用户将终端设备的位置移动，会导致对星失败，从而导致通话中断，影响用户体验。
有鉴于此，本申请实施例提供一种卫星通话方法，在通话界面中显示对星指示信息，以指示对星情况。同时，监测对星情况，在终端设备超出预设对星范围时，在通话界面中显示提示信息，以提示用户终端设备偏移，便于用户及时调整终端设备的位置，防止通话中断，提高用户体验。
另外，终端设备在卫星通信时，为了提升上行性能，使用的功率放大器(power amplifier，PA)的发送功率比较大，通常需要达到4瓦特(W)至5W。这样的话，终端设备的辐射就比较大，对于头模场景(例如卫星通话)，比吸收率(specific absorption rate，SAR)容易超标。而如果为了满足SAR指标降低PA的发射功率，会导致通信中断，例如通话容易中断。
有鉴于此，本申请实施例还提供一种卫星通话方法，通过确定终端设备连接的音频设备，确定通话模式为无线音频设备模式、有线音频设备模式或者免提模式，并在通话界面中去除听筒模式。如此，一方面能够防止用户使用听筒模式接听电话，进而降低辐射对用户头部的影响，提高用户体验；另一方面能够防止用户因使用听筒模式而随意移动终端设备的位置，防止终端设备偏离对星位置，进而防止通话中断，进一步提高用户体验。
本申请实施例提供的卫星通话方法可以应用于手机、平板电脑、可穿戴设备、车载设备、增强现实(augmented reality，AR)/虚拟现实(virtual reality，VR)设备、笔记本电脑、超级移动个人计算机(ultra-mobile personal computer，UMPC)、上网本、个人数字助理(personal digital assistant，PDA)等具有卫星通信功能的终端设备上，本申请实施例对终端设备的具体类型不作任何限制。

I2S接口可以用于音频通信。在一些实施例中，处理器110可以包含多组I2S总线。处理器110可以通过I2S总线与音频模块170耦合，实现处理器110与音频模块170之间的通信。在一些实施例中，音频模块170可以通过I2S接口向无线通信模块160传递音频信号，实现通过蓝牙耳机接听电话的功能。
PCM接口也可以用于音频通信，将模拟信号抽样，量化和编码。在一些实施例中，音频模块170与无线通信模块160可以通过PCM总线接口耦合。在一些实施例中，音频模块170也可以通过PCM接口向无线通信模块160传递音频信号，实现通过蓝牙耳机接听电话的功能。I2S接口和PCM接口都可以用于音频通信。
UART接口是一种通用串行数据总线，用于异步通信。该总线可以为双向通信总线。它将要传输的数据在串行通信与并行通信之间转换。在一些实施例中，UART接口通常被用于连接处理器110与无线通信模块160。例如：处理器110通过UART接口与无线通信模块160中的蓝牙模块通信，实现蓝牙功能。在一些实施例中，音频模块170可以通过UART接口向无线通信模块160传递音频信号，实现通过蓝牙耳机播放音乐的功能。
MIPI接口可以被用于连接处理器110与显示屏194，摄像头193等外围器件。MIPI接口包括摄像头串行接口(camera serial interface，CSI)，显示屏串行接口(display serial interface，DSI)等。在一些实施例中，处理器110和摄像头193通过CSI接口通信，实现终端设备100的拍摄功能。处理器110和显示屏194通过DSI接口通信，实现终端设备100的显示功能。
GPIO接口可以通过软件配置。GPIO接口可以被配置为控制信号，也可被配置为数据信号。在一些实施例中，GPIO接口可以用于连接处理器110与摄像头193，显示屏194，无线通信模块160，音频模块170，传感器模块180等。GPIO接口还可以被配置为I2C接口，I2S接口，UART接口，MIPI接口等。

终端设备可以将方位角偏差和俯仰角偏差显示于界面中，当终端设备基于该方位角偏差和俯仰角偏差，确定天线的辐射方向未对准需要通信的卫星时，终端设备可以显示引导对星信息，引导对星信息用于提示并引导用户调整终端设备的姿态，使得天线的辐射方向对准卫星。当终端设备基于该方位角偏差和俯仰角偏差确定天线的辐射方向对准卫星时，终终端设备可以显示对星成功的提示信息，以提示用户卫星天线的辐射方向已对准卫星。可选的，终端设备可以通过确定方位角偏差是否位于预设方位角范围a内，以及确定俯仰角偏差是否位于预设仰角范围a内，从而确定天线的辐射方向是否对准卫星。
在对星完成后，用户可以通过终端设备中的通话应用程序进行卫星通话。通话操作的过程与蜂窝通信下的通话操作过程类似，不再赘述。
下面对卫星通话过程中，本申请提供的方法的具体实现进行说明。

S101、在卫星通话的过程中，应用程序框架层的偏差确定模块实时确定终端设备的天线辐射方向的方位角与卫星传输链路方向的方位角之间的偏差，得到方位角偏差，并确定终端设备的天线辐射方向的俯仰角与卫星传输链路方向的俯仰角之间的偏差，得到俯仰角偏差。
S102、偏差确定模块将方位角偏差和俯仰角偏差发送至应用层的通话应用程序。
S103、通话应用程序根据方位角偏差和俯仰角偏差，在通话界面中显示对星指示信息，对星指示信息用于指示终端设备的对星情况，即天线辐射方向与卫星传输链路方向的方位角偏差和俯仰角偏差情况。
可选的，对星指示信息可以以文字、图片、动画等形式显示，本申请实施例对此不作任何限定。
示例性的，图5为本申请实施例提供的一例通话界面的示意图。以终端设备为手机为例，如图5所示，在卫星通话过程中，通话界面501中可以显示对星指示信息。其中，对星指示信息以动画形式为例示出。对星指示信息包括卫星示意图5021、预设方位角范围b的示意区域5022、预设俯仰角范围b的示意区域5023和俯仰角示意信息5024等。若卫星示意图5021位于预设方位角范围b的示意区域5022内，则说明方位角偏差在预设方位角范围b内。若俯仰角示意信息5024位于预设俯仰角范围b的示意区域5023内，则说明俯仰角偏差位于预设俯仰角范围b内。若手机位置发生移动，其方位角和俯仰角发生变化，则卫星示意图5022的位置和俯仰角示意信息5024可以跟随手机位置的移动而动态变化，形成动画效果。
S104、通话应用程序确定是否方位角偏差超出预设方位角范围b(也称为第一方位角范围)，和/或俯仰角偏差超出预设俯仰角范围b(也称为第一俯仰角范围)；若是，则执行步骤S105；若否，则返回执行步骤S101。

S105、通话应用程序在通话界面中显示提示信息，提示信息用于提示用户终端设备存在通话中断的可能性。
方位角偏差超出预设方位角范围b，和/或俯仰角偏差超出预设俯仰角范围b，说明方位角偏差和俯仰角偏差中至少一个较大，终端设备当前的位置偏离预设的位置，天线的辐射方向与卫星传输链路方向之间的偏差较大，极大可能出现对星失败的情况，因而极大可能出现通话质量下降，通话中断的情况。因此，终端设备在通话界面中显示提示信息，向用户提示该情况。
可选的，提示信息可以以文字、图片、动画等形式显示，本申请实施例对此不作任何限定。
在一个具体的实施例中，提示信息可以如图6中的601所示，该提示信息601以文字形式为例，示出“手机已偏离对星位置，通话可能中断，请尽快调整手机方向”等信息。同时，对星指示信息随手机位置的改变而发生变化，如图6所示。

S201、在卫星通话的过程中，应用程序框架层的偏差确定模块实时确定终端设备的天线辐射方向的方位角与卫星传输链路方向的方位角之间的偏差，得到方位角偏差，并确定终端设备的天线辐射方向的俯仰角与卫星传输链路方向的俯仰角之间的偏差，得到俯仰角偏差。
该步骤S201与上述步骤S101相同，不再赘述。
S202、偏差确定模块将方位角偏差和俯仰角偏差发送至应用层的通话应用程序。
该步骤S202与上述步骤S102相同，不再赘述。
S203、通话应用程序根据方位角偏差和俯仰角偏差，在通话界面中显示对星指示信息，对星指示信息用于指示终端设备的对星情况，即天线辐射方向与卫星传输链路方向的方位角偏差和俯仰角偏差情况。
该步骤S203与上述步骤S103相同，不再赘述。
S204、在卫星通话的过程中，通话应用程序实时获取卫星通信的信号强度。
可选的，通话应用程序可以通过电话管理器获取卫星通信信号的强度。
可选的，卫星通信的信号强度可以通过接收信号强度指示(received signal strength indicator，RSSI)、参考信号接收功率(reference signal receiving power，RSRP)、参考信号接收质量(reference signal receiving quality，RSRQ)、信号与干扰加噪声比(signal to interference plus noise ratio，SINR)和信噪比(signal to noise ratio，SNR)等中的一项或多项表征。
S205、通话应用程序确定是否满足卫星通信的信号强度小于预设阈值，并且，满足方位角偏差超出预设方位角范围c(也称为第二方位角范围)和俯仰角偏差超出预设俯仰角范围c(也称为第二俯仰角范围)中的至少一者；若是，则执行步骤S206；若否，则返回执行步骤S201。
换句话说，通话应用程序确定卫星通信的信号强度是否小于预设阈值，确定方位角偏差是否超出预设方位角范围c，并确定俯仰角偏差是否超出预设俯仰角范围c。若满足下面三种情况中的任一种，则执行步骤S206，否则返回执行步骤S201：
情况一：信号强度小于预设阈值，且方位角偏差超出预设方位角范围c；
情况二：信号强度小于预设阈值，且俯仰角偏差超出预设俯仰角范围c；
情况三：信号强度小于预设阈值，且方位角偏差超出预设方位角范围c，且俯仰角偏差超出预设俯仰角范围c。
可选的，预设阈值可以根据实际需求设置。预设方位角范围c可以与预设方位角范围b相同，也可以与预设方位角范围b不同。预设俯仰角范围c可以与预设俯仰角范围b相同，也可以与预设俯仰角范围c不同。
卫星通信的信号强度小于预设阈值，说明信号强度弱，当前卫星通信质量下降，可能出现通话中断的情况。方位角偏差超出预设方位角范围c和/或俯仰角偏差超出预设俯仰角范围c，说明方位角偏差和俯仰角偏差中至少一个较大，终端设备当前的位置偏离预设的位置，天线的辐射方向与卫星传输链路方向之间的偏差较大，极大可能出现对星失败的情况，进一步说明终端设备极大可能出现通话质量下降，通话中断的情况。因此，终端设备在通话界面中显示提示信息，向用户提示该情况。
可选的，提示信息可以与上述实施例中的提示信息相同或相似，不再赘述。
在一个具体的实施例中，预设方位角范围c大于预设方位角范围b，和/或，预设俯仰角范围c大于预设俯仰角范围b。也就是说，预设方位角范围c大于预设方位角范围b，以及，预设俯仰角范围c大于预设俯仰角范围b二者中至少一者满足。例如，预设方位角范围b可以为[-12°，12°]，预设俯仰角范围b可以为[-7°，7°]。
本实施例中，相较于上图4所示的方案，预设方位角范围c大于预设方位角范围b，和/或，预设俯仰角范围c大于预设俯仰角范围b，也即将判断方位角偏差和俯仰角偏差情况的条件放宽，这样，将放宽后的方位角偏差和俯仰角偏差，与卫星通信的信号强度一起作为判断条件，判断当前通话质量情况，提高判断结果准确度的同时，能够防止判断条件过于苛刻，从而防止过于频繁的显示提示信息而打扰用户，进一步提高用户体验。
S206、通话应用程序在通话界面中显示提示信息，提示信息用于提示用户终端设备存在通话中断的可能性。
该步骤S206与上述步骤S105相同，不再赘述。
本实施例提供的卫星通话方法，在卫星通话过程中，通过实时获取方位角偏差和俯仰角偏差，根据方位角偏差和俯仰角，在通话界面中显示对星指示信息。如此，用户能够在卫星通话过程中，随时获知终端设备的对星情况，防止因用户移动终端设备位置导致对星失败，进而防止通话中断，提高用户体验。同时，本实施例提供的卫星通话方法还实时获取卫星通信的信号强度，在满足卫星通信的信号强度小于预设阈值，并且，满足方位角偏差超出预设方位角范围c和俯仰角偏差超出预设俯仰角范围c中一者时，在通话界面中显 示提示信息，进一步提示用户可能出现通话中断的情况，便于用户及时调整手机位置，防止通话中断，提高用户体验。该方法中，将卫星通信的信号强度加入显示提示信息的判断条件中，使终端设备只有在信号强度弱，且方位角偏差和俯仰角偏差中至少一个较大的情况下，才显示提示信息，提高了通话质量判断的准确性，从而提高提示信息显示的准确性，提高用户体验。
下面对卫星通话过程中，通话模式的选择，以及对应通话界面的显示等进行说明。
可以理解，一般的，终端设备的通话模式可以包括无线音频设备模式(也称为第二模式)、有线音频设备模式(也称为第一模式)、免提模式和听筒模式等。其中，无线音频设备模式是指通过与终端设备无线连接的音频设备通话的模式。与终端设备无线连接的音频设备例如可以为：与终端设备通过蓝牙连接的音箱、与终端设备通过Wi-Fi连接的耳机、与终端设备通过蓝牙连接的车载设备等。本申请实施例对于音频设备与终端设备之间无线连接的方式，以及音频设备的具体类型等不做任何限定。有线音频设备模式是指通过与终端设备有线连接的音频设备通话的模式。与终端设备有线连接的音频设备例如可以为：与终端设备有线连接的音箱、耳机、车载终端设备等。免提模式是指通过终端设备自身的扬声器和麦克风等通话的模式。听筒模式是指通过终端设备自身的受话器和麦克风等通话的模式。
示例性的，图8是本申请实施例提供的又一例卫星通话方法的流程示意图。该方法可以通过应用程序层的通话应用程序实现。如图8所示，该方法可以包括：
S301、在确定当前正在进行卫星通话的情况下，确定是否存在与终端设备无线连接的音频设备，以及是否存在与终端设备有线连接的音频设备。
可选的，通话应用程序预先向耳机接口、蓝牙模块、Wi-Fi模块等订阅音频设备的连接情况，当耳机接口接入音频设备，或者蓝牙模块、Wi-Fi模块连接音频设备时，这些模块可以向通话应用程序发送通知，从而使通话应用程序能够及时获知终端设备与音频设备的连接情况。
S302、若存在与终端设备有线连接的音频设备，且不存在与终端设备无线连接的音频设备，则设置通话模式为有线音频设备模式，且在通话界面中显示免提模式的切换控件。免提模式的切换控件用于将通话模式切换为免提模式。
需要说明的是，这种情况下，通话界面中不包括听筒模式的切换控件，或者，通话界面中包括听筒模式的切换控件，但是该听筒模式的切换控件的功能被屏蔽，不可操作，即终端设备屏蔽对用户点击听筒模式的切换控件操作(即第一操作)的响应。也就是说，这种情况下，听筒模式不可用。可选的，在屏蔽听筒模式的功能的同时，可以将听筒模式的切换控件置灰显示，以便于用户更直观的获知该模式不可用，提高用户体验。
当用户点击免提模式的切换控件，将通话模式切换为免提模式后，通话界面中的免提模式的切换控件可以替换为无线音频设备模式的切换控件，或者，通话界面中的免提模式的切换控件的功能被屏蔽，置灰显示，在通话界面中增加显示无线音频设备模式的切换控件。无线音频设备模式的切换控件用于将通话模式切换为无线音频设备模式。换句话说，在存在与终端设备有线连接的音频设备，且不存在与终端设备无线连接的音频设备的情况下，终端设备的通话模式可以在免提模式和有线音频设备模式之间来回切换。
可以理解，本实施例提供的各个方案均可以与上述图4至图6实施例所示的方案结合。具体的，通话界面中在按照本实施例提供的方案显示各种通话模式的切换控件之外，也可以显示对星指示和提示信息等。本申请实施例对此不做任何限定。
示例性的，图9为本申请实施例提供的又一例通话界面的示意图。如图9中的(a)图所示，当前终端设备与一音频设备(以有线耳机为例)有线连接，且未与任何音频设备无线连接，这种场景下，通话应用程序将通话模式设置为有线音频设备模式，通话界面可以如图中的901所示，该通话界面901中可以包括免提模式的切换控件902。
用户点击免提模式的切换控件902可以将通话模式切换为免提模式，通话界面901中的免提模式的切换控件902被替换为有线音频设备模式的切换控件(图中示为“有线耳机”)903，如图9中的(b)图所示。
S303、若存在与终端设备有线连接的音频设备，且存在与终端设备无线连接的音频设备，则设置通话模式为有线音频设备模式，且在通话界面中显示无线音频设备模式和免提模式的切换控件。
与步骤S302不同的是，该步骤S303中，终端设备既有线连接音频设备，又无线连接音频设备。这种情况下，通话界面中，可以包括两个通话模式的切换控件，一个为免提模式的切换控件，另一个为无线音频设备模式的切换控件。如此，用户可以根据需求，点击对应的切换控件，选择将通话模式切换为免提模式或无线音频设备模式。
需要说明的是，这种情况下，通话界面中也不包括听筒模式的切换控件，或者，通话界面中包括听筒模式的切换控件，但是该听筒模式的切换控件的功能被屏蔽，不可操作。
可选的，可以直接在通话界面中设置免提模式的切换控件和无线音频设备的切换控件，也可以设置一个通话模式选择控件(也称为第一控件)，用户点击该通话模式选择控件后，进一步显示免提模式的切换控件和无线音频设备的切换控件。本申请实施例对于无线音频设备模式和免提模式的切换控件的具体显示方式不做任何限定。
当用户点击无线音频设备模式和免提模式的切换控件，将通话模式切换为免提模式或无线音频设备模式后，界面中被用户点击的切换控件不再显示，或者功能被屏蔽，界面中显示有线音频设备模式的切换控件。换句话说，在存在与终端设备有线连接的音频设备，且存在与终端设备无线连接的音频设备的情况下，终端设备的通话模式可以在有线音频设备模式、免提模式和无线音频设备模式之间来回切换。
示例性的，图10为本申请实施例提供的又一例通话界面示意图。如图10中的(a)图所示，当前终端设备与一音频设备(以有线耳机为例)有线连接，且与一音频设备(以蓝牙连接音频设备为例)无线连接，这种场景下，通话应用程序将通话模式设置为有线音频设备模式，通话界面可以如图中的1001所示，该通话界面1001中可以包括通话模式选择控件(图中示为“出声设备”控件)1002。
用户点击“出声设备”控件1002，界面中显示无线音频设备模式的切换控件(图中示为“蓝牙设备”)1003和免提模式的切换控件1004，如图10中的(b)图所示。
用户点击无线音频设备模式的切换控件1003，可以将通话模式切换为无线音频模式，之后界面恢复至图10中的(a)所示的界面1001。若用户点击界面1001中的通话模式选择控件1002，界面中显示有线音频设备模式的切换控件1005(图中示为“有线耳机”)和免提模式的切换控件1004，如图10中的(c)图所示。
用户点击免提模式的切换控件1004，可以将通话模式切换为免提模式，之后界面恢复至图10中的(a)所示的界面1001。若用户点击界面1001中的通话模式选择控件1002，界面中显示有线音频设备模式的切换控件1005(图中示为“有线耳机”)和无线音频设备模式的切换控件(图中示为“蓝牙设备”)1003，如图10中的(d)图所示。
S304、若存在与终端设备无线连接的音频设备，且不存在与终端设备有线连接的音频设备，则设置通话模式为无线音频设备模式，且在通话界面中显示免提模式的切换控件。
这种情况下，通话界面中也不包括听筒模式的切换控件，或者，通话界面中包括听筒模式的切换控件，但是该听筒模式的切换控件的功能被屏蔽，不可操作。
与步骤S302类似，这种情况下，终端设备的通话模式可以在无线音频设备模式和免提模式之间来回切换，不再赘述。
示例性的，图11为本申请实施例提供的又一例通话界面的示意图。如图11中的(a)所示，当前终端设备与一音频设备(以蓝牙连接音频设备为例)无线连接，且未与任何音频设备有线连接，这种场景下，通话应用程序将通话模式设置为无线音频设备模式，通话界面可以如图中的1101所示，该通话界面1101中可以包括免提模式的切换控件1102。
用户点击免提模式的切换控件1102可以将通话模式切换为免提模式，通话界面1101中的免提模式的切换控件1102被替换为无线音频设备模式的切换控件(图中示为“蓝牙设备”)1103，如图11中的(b)图所示。
S305、若不存在与终端设备无线连接的音频设备，且不存在与终端设备有线连接的音频设备，则设置通话模式为免提模式。
这种情况下，通话界面中也不包括听筒模式的切换控件，或者，通话界面中包括听筒模式的切换控件，但是该听筒模式的切换控件的功能被屏蔽，不可操作。
示例性的，图12为本申请实施例提供的又一例通话界面的示意图。如图12所示，当前终端设备未与任何音频设备无线连接，且未与任何音频设备有线连接，这种场景下，通话应用程序将通话模式设置为免提模式，通话界面可以如图12中的1201所示，该通话界面1201中不包括听筒模式的切换控件，也不包括其他通话模式的切换控件。
需要说明的是，上述步骤S301至S305，可以实时执行，也可以周期性执行，还可以在终端设备有线连接或无线连接的音频设备发生变化时执行。本申请实施例对此不做任何限定。
总而言之，本申请实施例中，在卫星通话的过程中，根据当前与终端设备无线连接的音频设备，以及当前与终端设备有线连接的音频设备的情况，智能地设置通话模式，且在界面中显示通话模式的切换控件，符合用户的多种使用场景，提高用户体验。而且，在设置通话模式时，不设置听筒模式，且在通话界面中不显示听筒模式的切换控件，或者显示听筒模式的切换控件，但是将该切换控件的功能屏蔽，使其不可操作。如此，在卫星通话过程中，用户不可使用听筒模式进行通话，一方面能够降低卫星通话过程中辐射对用户头部的影响，提高用户体验；另一方面能够防止用户因使用听筒模式而随意移动终端设备的位置，防止终端设备偏离对星位置，进而防止通话中断，进一步提高用户体验。
