Description

一种通话处理方法、装置及终端 技术领域
本文涉及但不限于通信领域，尤其涉及一种通话处理方法、装置及终端。
背景技术
现有的通话协议的带宽分为窄带(NB，Narrow Band)和宽带(WB，Wide Band)，超宽带(SWB，Super Wide Band)是后续高清语音的技术发展方向。超宽带语音技术的应用显著提升了通话音效，该技术的带宽是传统通话的四倍，是高清语音通话音频带宽的两倍。
运营商网络里既有宽带语音也有窄带语音，每次通话会根据网络情况调整容量操作点(COP，Capacity Operating Point)，有时候使用宽带语音，有时候使用窄带语音。但是在高通平台上，SO73网络下通话时音频数字信号处理器(ADSP，Audio Digital Signal Processor)都会工作在宽带语音的处理算法上，如果实际通话时使用的是窄带语音，最终播放出来就可能会听到杂音和噪音。
为提高通话质量，相关技术的处理方法一般是：利用传感器检测某些变量，在满足条件的情况下，通过增大受话器的音量(响度)来提升通话体验。这种技术的弊端在于：只局限于音量大小改善不同环境下的通话体验，遗漏了不同网络环境下语音带宽对音质和用户体验的本质影响。特别是超宽带和宽带能带来更加丰富、更加细节、更加真实的体验。另外，在现有网络环境下，如果手机和网络同时支持窄带语音、宽带语音和超宽带语音，则手机优先选择超宽带语音与网络侧匹配，以提供优质的超宽带语音服务。但是，这种默认选择也存在一个弊端。例如记者采访、酒吧、机场、火车站、球赛场等，更加强调通话的清晰度和可辨识度，语音带宽越宽反而会带来更多的高频噪音，使得通话质量下降。这种情况下把语音带宽聚焦在人声的频率范围内，把其他频段的声音通过滤波器衰减反而更合适。
综上，相关技术的方案中终端不能适时选择合适的语音带宽类型，从而使得语音带宽对语音质量的提升没有充分表现出来，通话体验满意度急剧下 降。且会出现通话协议不匹配，甚至出现杂音的情况。

图3为本发明实施例通话处理装置的结构示意图。
本发明的实施方式
下文中将结合附图对本申请的实施例进行详细说明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互任意组合。
如图1所示，本发明实施例的通话处理方法，包括：
步骤101，根据终端所处环境，确定通话业务需采用的语音带宽类型及最大输出功率。
这里，终端和运营商网络同时支持窄带(NB)语音、宽带(WB)语音和超宽带(SWB)语音。本步骤根据终端所处环境，选择采用NB、WB或SWB，并且限定每种带宽下的最大输出功率，使得通话语音的辨识效果配合清晰效果，提升了不同环境下通话服务的质量。
步骤102，根据确定的语音带宽类型及最大输出功率，对通话业务进行处理。
这里，根据确定的语音带宽类型能够决定通话业务的清晰效果，比如，SWB能够提供超级高清语音服务，WB能够提供高清语音服务。而限定的最大输出功率能够决定通话业务的辨识效果，输出功率越大，语音响度越大，可辨识度越高。
本发明实施例的通话处理方法，能够适时选择合适的语音带宽类型和最大输出功率，从而提供适应于不同环境的更优质的通话服务，使语音带宽对 语音质量的提升得以充分表现，提高了通话质量，提升了通话体验满意度。解决了现有技术中语音带宽对语音质量的提升没有充分表现出来，通话体验满意度急剧下降的问题。
可选的，每种语音带宽类型与对应的最大输出功率所决定的工作带宽与输出功率的积分面积恒定，使得工作带宽与输出功率之间相互约束，表现为工作带宽增大则输出功率相应的减小，工作带宽减小则输出功率相应的增大，从而通话语音的辨识效果能够配合清晰效果，实现不同环境下最优的通话服务。
可选的，上述步骤101的步骤可以包括：
步骤1011，检测终端所处环境的噪音分贝值。
这里，通过检测环境中的噪音分贝值，能准确判断环境的嘈杂程度。
步骤1012，根据检测的噪音分贝值，确定通话业务需采用的语音带宽类型及最大输出功率。
这里，根据环境的嘈杂程度，来确定需采用的语音带宽类型和最大输出功率，能使得通话服务更适应于当前环境，提升用户的通话体验。
比如，在比较安静的环境中，可采用超级高清，但响度较低的语音服务；在相对嘈杂的环境中、可采用高清，响度适中的语音服务；在比较嘈杂的环境中，可采用清晰度较小，但响度较高的语音服务。
可选的，上述步骤1012可以包括：
步骤10121，若噪音分贝值小于预设的第一噪音阈值，则确定通话业务需采用的语音带宽类型为超宽带，且最大输出功率为预设的第一功率阈值。
为便于描述，本文将第一噪音阈值标记为M1，第一功率阈值标记为P1。
这里，在噪音分贝值小于M1时，可判断终端处于比较安静的环境，如卧室、会议室、郊外等。本步骤在这种情况下采用SWB，且最大输出功率为P1。
此时，输出功率最小，但完全满足通话响度需要，更多的能量用于拓展带宽。SWB的语音带宽为16千赫兹(Khz)，甚至为32Khz&48Khz，足够的带宽能够表现更多的细节。SWB实现的超级高清语音服务使得通话更加的 真实和丰富。
步骤10122，若噪音分贝值大于第一噪音阈值且小于预设的第二噪音阈值，则确定通话业务需采用的语音带宽类型为宽带，且最大输出功率为预设的第二功率阈值；其中，第二噪音阈值大于第一噪音阈值，第二功率阈值大于第一功率阈值。
需要说明的是，第一噪音阈值和第二噪音阈值等可以参考一下参数进行设置：
类别  昼间  夜间
0类  50分贝  40分贝
1类  55分贝  45分贝
2类  60分贝  50分贝
3类  65分贝  55分贝
4类  70分贝  55分贝
其中，每一类标准的适用区域分别为：
(1)0类标准适用于疗养区、高级别墅区、高级宾馆区等特别需要安静的区域。位于城郊和乡村的这一类区域分别按严于0类标准5分贝执行。
(2)1类标准适用于以居住、文教机关为主的区域。乡村居住环境可参照执行该类标准。
(3)2类标准适用于居住、商业、工业混杂区。
(4)3类标准适用于工业区。
(5)4类标准适用于城市中的道路交通干线道路两侧区域，穿越城区的内河航道两侧区域。穿越城区的铁路主、次干线两侧区域的背景噪声(指不通过列车时的噪声水平)限值也执行该类标准。
为便于描述，本文将第二噪音阈值标记为M2，第二功率阈值标记为P2，M2>M1，且P2>P1。
这里，在噪音分贝值大于M1而小于M2时，可判断终端处于相对嘈杂的环境，如办公室、咖啡馆、西餐厅等。本步骤在这种情况下采用WB，且 最大输出功率为P2。
此时，输出功率适中，增加了部分能量用于提高通话响度。WB的语音带宽是8Khz。WB实现的高清语音服务，使通话在高清与响度之间达到一个平衡，提升了通话过程中的体验满意度。
步骤10123，若噪音分贝值大于第二噪音阈值，则确定通话业务需采用的语音带宽类型为窄带，且最大输出功率为预设的第三功率阈值；其中，第三功率阈值大于第二功率阈值。
为便于描述，本文将第三功率阈值标记为P3，P3>P2。
这里，在噪音分贝值大于M2时，可判断终端处于比较嘈杂的环境，如酒吧、机场、火车站、球赛场等。容易理解的是，在这种环境下，语音带宽越宽反而会带来更多的高频噪音，使得通话质量下降，把语音带宽聚焦在人声的频率范围内反而更合适。本步骤在这种情况下采用NB，且最大输出功率为P3。
需要说明的是，受话器工作时，第三功率阈值、第二功率阈值、第一功率阈值主要考虑额定功率和最大瞬时功率等两个关键因素，例如：
额定功率：20mW；瞬时功率：50mW时，在安静的环境中(环境噪声小于55分贝)，此时限制输出功率在10mW；在相对嘈杂的环境中(55分贝<环境噪声<65分),此时限制输出功率管在20mW；在嘈杂的欢喜中，(环境噪声大于65分贝)，此时限制输出功率在40mW。根据输出功率大小设置功率阈值。
此时，输出功率最大，更多的能量用于提高通话响度。NB的语音带宽是4Khz，把语音带宽聚焦在人声的频率范围内，并通过增加响度，提高了通话的可辨识度，保证了噪声环境下的基本通话需求。
可见，本发明实施例的通话处理方法，能够根据环境适时选择合适的语音带宽类型和最大输出功率，从而提供适应于不同环境的更优质的通话服务，使语音带宽对语音质量的提升得以充分表现，提高了通话质量，提升了通话体验满意度。
可选的，上述步骤102的步骤可以包括：
步骤1021，若语音带宽类型为超宽带，调用对应的超宽带语音算法对通话业务进行处理，并根据第一功率阈值，对经过超宽带语音算法处理的通话业务的输出信号的大小进行调整。
这里，超宽带语音算法采用的带宽是16Khz，采样率是32Khz甚至更高，语音信号的编解码的带宽到32Khz。本步骤调用超宽带语音算法，即超宽带语音的音频处理算法，实现通话过程中的编解码、回声抑制、降噪等，并根据P1调整输出信号的大小，实现输出功率的变化。
步骤1022，若语音带宽类型为宽带，调用对应的宽带语音算法对通话业务进行处理，并根据第二功率阈值，对经过宽带语音算法处理的通话业务的输出信号的大小进行调整。
这里，宽带语音的音频处理算法采用的带宽是8Khz，采样率是16Khz，语音信号的编解码的带宽到8Khz。本步骤调用宽带语音算法，即宽带语音的音频处理算法，实现通话过程中的编解码、回声抑制、降噪等，并根据P2调整输出信号的大小，实现输出功率的变化。
步骤1023，若语音带宽类型为窄带，调用对应的窄带语音算法对通话业务进行处理，并根据第三功率阈值，对经过窄带语音算法处理的通话业务的输出信号的大小进行调整。
这里，窄带语音的音频处理算法采用的带宽是4Khz，采样率是8Khz，语音信号的编解码的带宽到4Khz。本步骤调用窄带语音算法，即窄带语音的音频处理算法，实现通话过程中的编解码、回声抑制、降噪等，并根据P2调整输出信号的大小，实现输出功率的变化。
需要说明的是，对经过超宽带语音算法处理的通话业务的输出信号的大小进行调整参数进行输出信号调整、对经过宽带语音算法处理的通话业务的输出信号的大小进行调整、以及对经过窄带语音算法处理的通话业务的输出信号的大小进行调整为本领域技术人员的惯用技术手段，在此不做赘述。
此时，根据环境及采用的语音带宽类型，及时调整音频处理算法，实现了不同语音带宽类型的效果，保证并提高了通话质量。
可选的，上述步骤102的步骤还可以包括：
步骤1024，将确定的语音带宽类型通知给网络，使网络根据语音带宽类型设置所处的带宽类型。
这里，网络同时支持NB、WB和SWB。
此时，通过将确定的语音带宽类型通知给网络，使网络与终端处于相同的语音带宽，避免了终端与网络通话协议不匹配，甚至出现杂音的情况，提高了通话质量。
本发明实施例还提供一种计算机存储介质，计算机存储介质中存储有计算机可执行指令，计算机可执行指令用于执行上述通话处理方法。
假定本发明实施例的通话处理方法应用于手机，手机与网络同时支持NB、WB和SWB。该方法在终端与网络匹配的情况下，根据环境确定通话中采用的网络语音类型，并及时调整音频处理算法，提供优质的语音服务，保证并提高了通话质量。
可选的，手机上的麦克风检测环境噪音，当手机检测到当前处于安静环境时(噪音分贝值小于M1)，代表的环境有卧室、会议室、山谷、郊外等。则手机调用图2-C示意的音频处理算法，手机的受话器工作在SWB模式下，功率(见图2中的能量参数：20mW)最小但是完全满足通话响度需要，更多的能量用于拓展受话器带宽(见图2中的频率)。其中，手机和网络匹配且均处于超宽带语音。利用超宽带语音网路，提供超级高清语音服务，足够的带宽能够表现更多的细节，使得通话更加的真实和丰富。
当手机检测到当前处于相对嘈杂的环境时(M1<噪音分贝值<M2)，代表环境有办公室、咖啡馆、西餐厅等。则手机调用图2-B示意的音频处理算法，手机的受话器工作在WB模式下，功率(见图2中的能量参数：40毫瓦(mW))适中。其中，手机和网络匹配且均处于宽带语音。利用宽带语音网路，提供高清语音服务，同时增加响度，在高清和响度之间达到一个平衡，提升了通话过程中的体验满意度。
当手机检测到当前处于嘈杂的环境时(噪音分贝值>M2)，代表环境有 酒吧、机场、火车站、球赛场等。则手机调用图2-A示意的音频处理算法，手机的受话器工作在NB模式下，但是受话器功率(见图2中的能量参数：50mW)最大，更多的能量用于提高受话器的响度。其中，手机和网络匹配且均处于窄带语音。此时，强调通话的可辨识度，因此，通过提升响度或者功率来满足用户体验，但是，窄带语音网络下的语音质量也得到满足。
其中，图2中A、B、C三种音频处理算法，受话器的工作带宽与功率积分面积恒定，表现为A、B、C对应的三个梯形的面积相等，均等于一固定值S。
综上，本发明实施例的通话处理方法，能够适时选择合适的语音带宽类型和最大输出功率，从而提供适应于不同环境的更优质的通话服务，使语音带宽对语音质量的提升得以充分表现，提高了通话质量，提升了通话体验满意度。解决了现有技术中语音带宽对语音质量的提升没有充分表现出来，通话体验满意度急剧下降的问题。并且通过与网络匹配，使网络与终端处于相同的语音带宽，避免了终端与网络通话协议不匹配，甚至出现杂音的情况。
