Description

一种终端的通话切换方法、系统及终端、计算机存储介质 技术领域
本发明涉及通信技术,尤其涉及一种终端的通话切换方法、系统及终端、计算机存储介质。
背景技术
随着通信技术的快速发展,具有通话功能的终端设备越来越多,使得人们可采用的通讯方式也越来越多样化。此外,为了满足个人需求,越来越多的人喜欢随身携带多个终端设备,例如手中拿着一台智能手机,而手腕上带着一只智能手表。因此,用户可利用终端设备所具有的通话功能,使终端设备之间进行通话切换,以实现在不同终端设备上完成通话。例如,当用户甲在使用智能手机与用户乙进行通话的过程中,因遇到意外情况而不能使用智能手机与用户乙进行通话,但同时想继续与用户乙的通话时,可将该通话切换到智能手表上,以实现利用智能手表完成通话。
然而,现有的通话切换基本都需要依靠蓝牙实现,其实现过程包括:首先,需要在智能手机与具有通话功能的终端设备之间建立蓝牙连接;其次,在需要使用该终端设备进行通话时,采用触摸按键等手动方式将通话切换至该终端设备上;最后,智能手机将通信对方所发送过来的语音流传输给该终端设备,而将该终端设备发送过来的语音流传输给该通信对方,从而实现将智能手机与通信对方的通话切换为该终端设备与通信对方的通话。
但是,现有的通话切换存在以下问题:当智能手机与终端设备之间的蓝牙连接中断之后,终端设备与通信对端之间的通话会中断,需要再次建立两者之间的蓝牙连接,而建立蓝牙连接需要一定时间,无法实现终端设备之间通话的无缝切换。此外,当终端设备与通信对端之间建立通话后,智能手机与终端设备之间不能实现通话,即不能实现智能手机、终端设备和通信对端相互之间的“三方通话”。

具体实施方式
实施例一
图1为本发明实施例一终端的通话切换方法的实现流程示意图,该方法包括:
步骤101:第一终端接收第一语音信号,并对所述第一语音信号进行识别;
一实际应用中,用户通过第一终端中设置的第一声音输入装置直接输入第一语音信号或间接输入第一语音信号,第一终端接收到所述第一语音信号后,对所述第一语音信号进行识别,包括:检测所述第一语音信号的大小是否大于预设第一阈值且持续时间是否大于预设第二阈值,和/或,检测与所述第一语音信号的声音源的距离是否小于预设第三阈值;若第一终端检测到所述第一语音信号的大小大于预设第一阈值且持续时间大于预设第二阈值、和/或与所述第一语音信号的声音源的距离小于预设第三阈值,则第一终端将所述第一语音信号识别为通话切换请求。
这里,所述第一终端可以是具有通话功能的终端设备,比如智能手表等;所述用户通过第一终端中设置的第一声音输入装置直接输入第一语音信号可以是用户对第一终端中的第一声音输入装置比如话筒输入语音,若第一终端中设置的第一声音接收装置比如声音传感器感知到该语音,则可认为所述第一终端接收到所述第一语音信号;所述用户通过第一终端中设置的第一声音输入装置间接输入第一语音信号可以是预先将一条或一条以上语音存储在第一终端中,用户通过触发设置在第一终端上的播放按键以实现所述第一终端播放所述存储的任意一条语音,若第一终端中设置的第一声音接收装置比如声音传感器感知到所述存储的任意一条语音,则可认为所述第一终端接收到所述第一语音信号;或者,所述用户通过第一终端中设置的第一声音输入装置间接输入第一语音信号也可以是预先将一条或一条以上语音存储在除所述第一终端以外的终端中,若第一终端中设置的第一声音接收装置比如声音传感器感知到该终端播放所述存储的任意一条 语音,则可认为所述第一终端接收到所述第一语音信号。
这里,所述第一阈值、第二阈值、第三阈值可根据实际应用需求进行设置,比如可将所述第一阈值设置为20dB、第二阈值设置为1s、第三阈值设置为10cm;需要注意的是,所述第一阈值、第二阈值、第三阈值等三个阈值的大小关系到对所述第一语音信号进行识别的结果;例如,当第一阈值太小或第三阈值太大时,则容易使第一终端将外界任意一个语音信号识别为通话切换请求。
这里,所述第一终端检测与所述第一语音信号的声音源的距离可通过所述第一终端中设置的距离传感器比如渐进传感器实现;所述距离的保持时间是否大于或等于预设第四阈值也可以作为所述第一终端将所述第一语音信号识别为通话切换请求时需要满足的条件,即第一终端检测到与所述第一语音信号的声音源的距离小于预设第三阈值且所述距离的保持时间大于或等于预设第四阈值时,才将所述第一语音信号识别为通话切换请求。
步骤102:当将所述第一语音信号识别为通话切换请求且确认与第一终端已建立数据连接的第二终端当前处于通话状态时,第一终端向所述第二终端发送通话切换请求;

这里,第一终端可通过向与所述第一终端已建立数据连接的第二终端发送检测所述第二终端当前是否处于通话状态的指令,然后根据所述第二终端对所述指令的反馈结果判断所述第二终端当前是否处于通话状态;或者,所述第一终端可通过检测与所述第一终端已建立数据连接的第二终端的通话状态标识,以根据所述通话状态标识确认所述第二终端当前是否处于通话状态。
在本发明实施例一实施方式中,所述当将所述第一语音信号识别为通话切换请求后,该方法还可包括:
第一终端搜索第二终端的标识,根据所述第二终端的标识向所述第二 终端发送数据连接请求;
第二终端接收所述第一终端发送的所述数据连接请求,并根据所述数据连接请求与所述第一终端建立数据连接。
一实际应用中,第一终端通过自身所具有的搜索和发现处于所述第一终端附近的终端设备的功能,搜索处于所述第一终端附近的终端设备的标识;当搜索到所述第二终端的标识后,第一终端根据所述第二终端的标识向所述第二终端发送数据连接请求,以请求与所述第二终端建立数据连接;第二终端接收到所述第一终端发送的所述数据连接请求后,接受所述数据连接请求,以与所述第一终端建立数据连接。
这里,所述第一终端还可通过所述第一终端中已有的且包括第二终端的标识在内的终端标识列表获取所述第二终端的标识,然后再根据所述第二终端的标识向所述第二终端发送数据连接请求。
这里,所述数据连接可以是无线网络连接,即第一终端和第二终端都具备接入无线网络的能力且两者之间还可依靠无线网络相互进行数据传输。
这里,若所述第一终端与第二终端在步骤101之前或之后已建立数据连接即第一终端与第二终端之间已能够实现数据传输,则第一终端可不必根据第二终端的标识向所述第二终端发送数据连接请求,以与第二终端再次或重新建立数据连接。
步骤103:第二终端接收所述第一终端发送的所述通话切换请求,并将与所述第二终端正在通话的第三终端所发送的第二语音信号向所述第一终端发送;
一实际应用中,第二终端接收到与所述第二终端已建立数据连接的第一终端在步骤102中所发送的通话切换请求后,将接收到的与所述第二终端正在通话的第三终端所发送的第二语音信号向所述第一终端发送,以将所述第二终端与第三终端之间的通话切换为第一终端与第三终端之间的通话。
这里,所述第二终端、第三终端可以是具有通信功能的终端设备,比 如智能手机等。
步骤104:第一终端接收所述第二终端发送的所述第二语音信号,解析出所述第二语音信号所对应的第一语音数据,并输出所述第一语音数据;
一实际应用中,第一终端接收所述第二终端在步骤103中所发送的所述第二语音信号,解析出所述第二语音信号所对应的第一语音数据,然后通过所述第一终端中设置的第一声音输出装置比如听筒或扬声器等输出所述第一语音数据,以实现用户通过所述第一终端接听所述第三终端所发送的通话语音。
步骤105:第一终端接收第三语音信号,并向所述第二终端发送所述第三语音信号;
一实际应用中,当第一终端在步骤104中输出所述第一语音数据后,接收对所述第一语音数据进行响应的第三语音信号,并向所述第二终端发送所述第三语音信号,以使所述第二终端向所述第三终端发送所述第三语音信号。
这里,所述第三语音信号可认为是用户对所述第一终端所输出的所述第一语音数据的反馈信号,用以完成所述第一终端与所述第三终端之间的通话交互。
步骤106:第二终端接收所述第一终端发送的所述第三语音信号,并将所述第三语音信号向所述第三终端发送。
一实际应用中,第二终端接收到所述第一终端在步骤105中发送的所述第三语音信号后,将所述第三语音信号向所述第三终端发送,以实现第一终端与第三终端之间的通话交互。
在本发明实施例一实施方式中,该方法还可包括:
第二终端解析出所述第三语音信号所对应的第二语音数据,并输出所述第二语音数据;
第二终端接收第四语音信号,并向所述第一终端和第三终端发送所述第四语音信号。

这里,所述第四语音信号可认为是用户对所述第二终端所输出的所述第二语音数据的反馈信号,以实现所述第二终端与所述第一终端之间的通话交互;所述第四语音信号可以是用户通过所述第二终端中设置的第二声音输入装置比如话筒直接输入语音,若所述第二终端中的第二声音接收装置比如声音传感器感知到该语音,则可认为所述第二终端接收到所述第四语音信号。
在本发明实施例一实施方式中,当第三终端接收到所述第二终端发送的所述第三语音信号后,解析出所述第三语音信号所对应的第二语音数据,并通过所述第三终端中设置的第三声音输出装置比如听筒或扬声器等输出所述第二语音数据,以实现用户通过所述第三终端接听所述第一终端发送的通话语音;然后,第三终端接收对所述第二语音数据进行响应的第五语音信号,并将所述第五语音信号向所述第二终端发送,以使所述第二终端将所述第五语音信号向所述第一终端发送。
这里,所述第五语音信号可认为是用户对所述第三终端所输出的所述第二语音数据的反馈信号,以实现所述第三终端与所述第一终端之间的通话交互;所述第五语音信号可以是用户通过所述第三终端中设置的第三声音输入装置比如话筒直接输入语音,若所述第三终端中的第三声音接收装置比如声音传感器感知到该语音,则可认为所述第三终端接收到所述第五语音信号。
在本发明实施例一实施方式中,当第二终端接收到所述第三终端发送的所述第五语音信号后,将所述第五语音信号向所述第一终端发送,以使所述第一终端解析并输出与所述第五语音信号所对应的语音数据;并且,第二终端还解析并输出与所述第五语音信号所对应的语音数据,以实现第二终端与第一终端之间的通话交互。

采用本发明实施例,第一终端接收第一语音信号,并对所述第一语音信号进行识别;当将所述第一语音信号识别为通话切换请求且确认与第一终端已建立数据连接的第二终端当前处于通话状态时,第一终端向所述第二终端发送通话切换请求;第二终端接收所述第一终端发送的通话切换请求,并将与所述第二终端正在通话的第三终端所发送的第二语音信号向所述第一终端发送;第一终端接收所述第二终端发送的所述第二语音信号,解析出所述第二语音信号所对应的第一语音数据,并输出所述第一语音数据;第一终端接收第三语音信号,并向所述第二终端发送所述第三语音信号;第二终端接收所述第一终端发送的第三语音信号,并将所述第三语音信号向所述第三终端发送;可见,本发明实施例通过当第一终端接收到通话切换请求且确认与第一终端已建立数据连接的第二终端当前处于通话状态时,向所述第二终端发送通话切换请求,以使所述第二终端将当前的通话切换至所述第一终端执行,即将第二终端与第三终端之间的通话切换为第一终端与第三终端之间的通话,从而实现了终端设备之间通话的无缝切换。
