在宽窄带互通环境下语音通信***中，窄带终端和宽带终端均发起呼叫。呼叫可以有两种形式组呼或者单呼。
在一些应用场景下，宽带终端和窄带终端需要呼叫另外一个窄带终端或宽带终端，也即单独呼叫，简称单呼。
在一些应用场景下若干终端可以组成群组，群组中的窄带终端或宽带终端可以呼叫群组中所有终端，也即群组呼叫，简称组呼。
在本申请中实施例中，在宽带终端呼叫宽带终端过程中是不会出现语音大小不一致的问题，在窄带终端呼叫窄带终端的过程中也不会出现语音大小不一致的问题。因此，本申请会着重于窄带终端与宽带终端之间的语音互通。
为了解决宽带终端与窄带终端之间语音互通不一致的问题，本申请主要是针对宽带终端的呼叫处理过程进行改进(还有一部分涉及IP多媒体子***IMS的变动，后续会详细描述)，窄带终端的呼叫处理过程未做变动。
为了解决宽带终端呼叫窄带终端时窄带终端出现啸叫的问题，在宽带终端呼叫窄带终端的情况下，所述宽带终端对语音数据的能量振幅执行缩小操作获得缩小语音数据包，发送所述缩小语音数据包至所述窄带终端，以供所述窄带终端播放所述缩小语音数据包，从而避免窄带终端出现啸叫。

由于组呼和单呼过程中宽带终端的处理过程是不一致的，为此，本申请分别对组呼的处理过程和单呼的处理过程分别进行描述。
首先介绍组呼处理过程，组呼处理过程依据发起方不同分为两个实施例。实施例一描述的为由宽带终端作为组呼发起方，实施例二描述的为由窄带终端作为组呼发起方。
参见图2，为一种宽窄带互通环境下语音通信方法的实施例一，可以包括以下步骤：
步骤S201：宽带终端向IP多媒体子***中的集群控制功能模块发送呼叫消息，其中，在组呼情况下所述呼叫消息包括组呼类型和终端组标识。
宽带终端预先已经与IP多媒体子***建立通信链接，宽带终端在需要发起组呼的情况下，会向IP多媒体子***中的集群控制功能模块也即TCF模块发送呼叫消息。
呼叫消息包括组呼类型和终端组标识，其中组呼类型可以告知TCF模块本次呼叫是组呼，终端组标识可以告知TCF模块本次组呼在终端组标识对应的终端组展开。
步骤S202：所述集群控制功能模块基于所述终端组标识确定终端组类型后生成反馈消息并发送所述反馈消息至所述宽带终端。其中，在所述终端组类型为既包含宽带终端又包含窄带终端的混合组的情况下，所述反馈消息携带有表示混合组的指示参数。
终端组包括两种类型：混合类型和纯宽带类型。混合类型的终端组为既包括窄带终端又包括宽带终端的终端组，纯宽带类型的终端组为均是宽 带终端的终端组。终端组暂时不包括纯窄带类型，纯窄带类型采用其它通信***处理，所以在本申请中暂不考虑。
TCF模块预先存储有各个终端组类型，通过终端组标识来确定终端所属的终端组类型。
在终端组类型为纯宽带类型的情况下，TCF模块生成反馈消息，反馈消息指示终端组类型为纯宽带类型。
在终端组类型为混合类型的情况下，TCF模块生成反馈消息，反馈消息指示终端组类型为混合类型。例如，在反馈消息中添加一个pdtcall参数，以用于指示终端组类型为混合类型。
步骤S203：所述宽带终端接收并识别所述反馈消息，在所述反馈消息携带有所述指示参数的情况下，构建两路语音数据包。其中，一路语音数据包为缩小能量振幅后的缩小语音数据包，另一路语音数据包为正常能量振幅的正常语音数据包。
宽带终端接收TCF模块发送的反馈消息并识别反馈消息，若反馈消息未携带有指示参数(也即指示终端组为混合类型的参数，延续上述举例中pdtcall参数)，则确认终端组类型为纯宽带类型，则宽带终端后续执行过程与现有技术组呼过程一致，不再赘述。
若反馈消息携带有指示参数(也即指示终端组为混合类型的参数，延续上述举例中pdtcall参数)，则确认终端组类型为混合类型，为了既能满足组呼中其余宽带终端正常播放语音数据包又能保证窄带终端不出现啸叫，所以宽带终端构建两路语音数据包。
其中，一路语音数据包为缩小能量振幅后的缩小语音数据包，用于发 送至终端组中的窄带终端，另一路语音数据包为正常能量振幅的正常语音数据包，用于发送至终端组中的其余宽带终端。
为了构建两路语音数据包，所述宽带终端采集语音数据并启用两个编码器：
对所述语音数据能量振幅执行缩小处理，将缩小能量振幅后的语音数据送入一路编码器，并在包头中添加类型字段且修改包头中类型字段为第一数值，基于所述包头和所述语音数据生成所述缩小语音数据包。
将语音数据送入另一路编码器，在包头中添加类型字段并修改包头中类型字段为第二数值，基于所述包头和所述语音数据生成所述正常语音数据包。
可以理解的是，宽带终端中预先存储有经过多次试验后确定的缩小倍数，宽带终端会按照缩小倍数来对能量振幅执行缩小操作。一般情况下，正常能量振幅约为14000～-24000，缩小能量振幅约为2000～-3000。
在包头中添加类型字段并修改为不同数值，其目的为通过类型字段便能够识别出两路语音数据包的去向，第一数值表示缩小语音数据包的去向为窄带终端，第二数值表示正常语音数据包的去向为宽带终端。
例如，在包头中添加type字段，TMF模块和终端都依据type字段来判断语音数据包是属于宽带终端的还是窄带终端，若type字段为0表示都转发，若type字段为1表示给窄带，若type字段为2表示给宽带。
为了便于设备区分两路语音数据包，可以采用一个同步源标志位SSRC来区分，两路语音数据包中的同步源标志位SSRC为不同数据值，例如，第一路SSRC值为随机生成的数据值，另一路SSRC值为第一路SSRC 数据值+1。
步骤S204：所述宽带终端交叉发送所述两路语音数据包至IP多媒体子***中的集群媒体功能集群媒体功能模块。
IP多媒体子***中的集群媒体功能模块(也即TMF模块)提供一个端口给宽带终端，宽带终端会交叉发送两路语音数据包至TMF模块的一个端口，以便TMF接收到两路语音数据包。这样可以占用TMF模块较少的网络资源。
步骤S205：所述集群媒体功能模块识别所述两路语音数据包，分发所述缩小语音数据包至所述终端组中的窄带***，分发所述正常语音数据包至所述终端组中的其余宽带终端。
TMF模块识别两路语音数据包的包头中类型字段，若一路语音数据包的包头中类型字段为第一数值，则删除所述语音数据包的包头中类型字段后，分发该语音数据包至窄带***。
为了避免影响到窄带***，所以删除包头中类型字段后再经过PDT网关发送至窄带***。若一路语音数据包的包头中类型字段为第二数值，则经过运营商***发送至终端组中的其余宽带终端。
步骤S206：其余宽带终端接收并识别所述正常语音数据包，在识别出所述正常语音数据包的包头中类型字段为第二数值后，确认是由宽带终端发送的语音数据包，直接播放所述正常语音数据包。
由于在组呼过程中宽带终端可能接收到是宽带终端发送的语音数据包，也可能是接收到的是窄带终端发送的语音数据包，所以宽带终端接收到语音数据包后需要识别包头中的类型字段。
在识别出语音数据包的包头中类型字段为第二数值后，确认是由宽带终端发送的正常语音数据包，由于宽带终端与宽带终端之间不存在语音不一致问题，所以直接播放所述正常语音数据包。
步骤S207：窄带***解析缩小语音数据包获得语音数据，发送该语音数据至窄带终端。
由所述窄带***解析缩小语音数据包获得语音数据后，发送该语音数据至所述终端组中的窄带终端。
由于窄带终端中不存在RTP包的概念，所以窄带***会解析该语音数据包，从而获得语音数据，并发送语音数据至终端组中的窄带终端。
步骤S208：终端组中窄带终端接收并播放窄带***发送的缩小语音数据包对应的语音数据。
通过实施例一可知，本实施例具有如下有益效果：
为了解决宽带终端呼叫窄带终端时窄带终端出现啸叫的问题，在宽带终端呼叫窄带终端的情况下，所述宽带终端对语音数据的能量振幅执行缩小操作获得缩小语音数据包，发送所述缩小语音数据包至所述窄带终端，以供所述窄带终端播放所述缩小语音数据包，从而避免窄带终端出现啸叫。
并且，在宽带终端发送两路语音数据包时交叉发送至TMF模块的一个端口，相比于占用TMF模块的两个端口而言，可以占用TMF模块较少的网络资源。
参见图3，为一种宽窄带互通环境下语音通信方法的实施例二，可以包括以下步骤：
步骤S301：在窄带终端向IP多媒体子***中的集群控制功能模块发送呼叫消息，其中，在组呼情况下所述呼叫消息包括组呼类型和终端组标识。
步骤S302：所述集群控制功能模块基于所述终端组标识确定终端组类型后生成反馈消息并发送所述反馈消息至所述窄带终端，且，在所述终端组类型为既包含宽带终端又包含窄带终端的混合组的情况下，所述反馈消息携带有表示混合组的指示参数。
步骤S301和步骤S303的过程与步骤S201和步骤S202的过程类似，再次不再重复赘述。
步骤S303：所述窄带终端接收并识别所述反馈消息，在所述反馈消息携带有所述指示参数的情况下，发送语音数据至窄带***。
步骤S304：所述窄带***基于语音数据生成语音数据包，发送语音数据包至IP多媒体子***中的集群媒体功能模块。
步骤S305：所述集群媒体功能模块为所述语音数据包的包头添加类型字段，并修改包头中类型字段为第一数值，分发该语音数据包至所述终端组中的宽带终端和窄带***。
由于窄带***经过网关传输而来的语音数据包是不携带类型字段的，为了便于TMF模块可以处理，TMF模块在识别到语音数据包是从窄带端口传来而来的情况下，为语音数据包添加类型字段，且修改包头中类型字段为第一数值，以用于表示是来自于窄带终端的语音数据包。
TMF模块在分发该语音数据包至所述终端组中的宽带终端和其余的窄带终端过程，包括：集群媒体功能模块识别该语音数据包的包头，若该 语音数据包的包头中类型字段为第一数值，则删除所述语音数据包的包头中类型字段后，分发该语音数据包至窄带***。详见步骤S205的详细解释在此不再赘述。
步骤S306：终端组中的宽带终端接收并识别该语音数据包，若该语音数据包的包头中类型字段为第一数值，则确认是由窄带终端发送的语音数据包，并对该语音数据包的能量振幅执行放大操作，获得放大语音数据包，播放所述放大语音数据包。
宽带终端在识别窄带终端发送而来的语音数据包之后，为了避免直接播放语音数据包声音较小的问题，对语音数据包的能量振幅执行放大操作，并播放放大语音数据包，从而解决窄带终端呼叫宽带终端时宽带终端侧声音较小的问题。
可以理解的是，宽带终端中预先存储有经过多次试验后确定的放大倍数，宽带终端会按照放大倍数来对能量振幅执行放大操作，从而获得放大语音数据包。
步骤S307：窄带***解析该语音数据包获得语音数据，发送该语音数据至窄带终端。
由所述窄带***解析缩小语音数据包获得语音数据后，发送该语音数据至所述终端组中的窄带终端。
由于窄带终端中不存在数据包的概念，所以窄带***会解析该语音数据包，从而获得语音数据，并发送语音数据至终端组中的窄带终端。
步骤S308：其余窄带终端接收并播放窄带***发送的缩小语音数据包对应的语音数据。
通过上述步骤可以得知本实施例二具有以下有益效果：
为了解决窄带终端呼叫宽带终端时宽带终端播放声音较小的问题，在窄带终端呼叫宽带终端的情况下，所述宽带终端接收语音数据包，并对所述语音数据包的能量振幅执行放大操作，获得放大语音数据包，由所述宽带终端播放所述放大语音数据包，从而解决宽带终端播放声音较小的问题。
下面介绍单呼处理过程，单呼处理过程依据发起方不同分为两个实施例。实施例三描述的为由宽带终端作为单呼发起方，实施例四描述的为由窄带终端作为组呼发起方。
参见图4，为一种宽窄带互通环境下语音通信方法的实施例三，可以包括以下步骤：
步骤S401：宽带终端向IP多媒体子***中的集群控制功能模块发送呼叫消息，其中，在单呼情况下所述呼叫消息包括单呼类型和终端标识。
宽带终端预先已经与IP多媒体子***建立通信链接，宽带终端在需要发起单呼的情况下，会向IP多媒体子***中的集群控制功能模块也即TCF模块发送呼叫消息。
呼叫消息包括单呼类型和终端标识，其中单呼类型可以告知TCF模块本次呼叫是单呼，终端标识可以告知TCF模块本次单呼的终端。
步骤S402：所述集群控制功能模块基于所述终端标识确定终端类型后生成反馈消息并发送所述反馈消息至所述宽带终端。其中，在所述终端类型为窄带终端的情况下，所述反馈消息携带有表示窄带终端的指示参数。
在终端类型为窄带终端的情况下，TCF模块生成反馈消息，反馈消息 指示终端类型为窄带终端。例如，在反馈消息中添加一个pdtcall参数，以用于指示终端类型为窄带终端。
步骤S403：所述宽带终端接收并识别所述反馈消息，在所述反馈消息携带有所述指示参数的情况下，构建一路缩小能量振幅后的缩小语音数据包。
若反馈消息携带有指示参数，则确认终端类型为窄带终端，为了能保证窄带终端不出现啸叫，所以宽带终端构建一路语音数据包。一路语音数据包为缩小能量振幅后的缩小语音数据包，用于发送至终端组中的窄带终端。
为了构建一路语音数据包，所述宽带终端启用一个编码器：采集语音数据，对语音数据能量振幅执行缩小处理，将缩小能量振幅后的语音数据送入一路编码器，编码器在包头中添加类型字段且修改包头中类型字段为第一数值，基于所述包头和所述语音数据生成所述缩小语音数据包。
可以理解的是，宽带终端中预先存储有经过多次试验后确定的缩小倍数，宽带终端会按照缩小倍数来对能量振幅执行缩小操作，从而获得缩小语音数据包。一般情况下，正常能量振幅约为14000～-24000，缩小能量振幅约为2000～-3000。
例如，在包头中添加type字段，TMF模块和终端都依据type字段来判断语音数据包是属于宽带终端的还是窄带终端，若type字段为0表示都转发，若type字段为1表示给窄带，若type字段为2表示给宽带。
步骤S404：所述宽带终端发送所述缩小语音数据包至IP多媒体子***中的集群媒体功能集群媒体功能模块。
IP多媒体子***中的集群媒体功能模块(也即TMF模块)提供一个端口给宽带终端，宽带终端会发送语音数据包至TMF模块的一个端口。
步骤S405：所述集群媒体功能模块识别所述缩小语音数据包，发送所述缩小语音数据包至窄带***。
TMF模块识别缩小语音数据包的包头中类型字段，若缩小语音数据包的包头中类型字段为第一数值，则删除所述语音数据包的包头中类型字段后，分发该语音数据包至窄带***。
为了避免影响到窄带***，所以删除包头中类型字段后再经过PDT网关发送至窄带***。由于窄带终端中不存在RTP包的概念，所以窄带***会解析该语音数据包，从而获得语音数据，并发送语音数据至终端组中的窄带终端。
步骤S406：窄带***解析所述语音数据包获得语音数据，并发送语音数据至终端标识对应的窄带终端。
由所述窄带***解析该语音数据包获得语音数据后，发送该语音数据至窄带终端。
步骤S407：窄带终端接收并播放所述缩小语音数据包对应的语音数据。
通过实施例三的技术特征，可以具有以下有益效果：
为了解决宽带终端呼叫窄带终端时窄带终端出现啸叫的问题，在宽带终端呼叫窄带终端的情况下，所述宽带终端对语音数据的能量振幅执行缩小操作获得缩小语音数据包，发送所述缩小语音数据包至所述窄带终端，以供所述窄带终端播放所述缩小语音数据包，从而避免窄带终端出现啸叫。
参见图5，为一种宽窄带互通环境下语音通信方法的实施例四，可以包括以下步骤：
步骤S501：在窄带终端向IP多媒体子***中的集群控制功能模块发送呼叫消息，其中，在单呼情况下所述呼叫消息包括单呼类型和终端标识。
步骤S502：所述集群控制功能模块基于所述终端标识确定终端类型后生成反馈消息并发送所述反馈消息至所述窄带终端，且，在所述终端类型为窄带终端的情况下，所述反馈消息携带有表示窄带终端的指示参数。
步骤S503：所述窄带终端接收并识别所述反馈消息，在所述反馈消息携带有所述指示参数的情况下，发送语音数据至窄带***。
步骤S504：由所述窄带***生成语音数据包后经网关发送至IP多媒体子***中的集群媒体功能模块。
步骤S505：所述集群媒体功能模块为所述语音数据包的包头添加类型字段，并修改包头中类型字段为第一数值，分发该语音数据包至所述终端标识对应的宽带终端。
由于窄带***经过网关传输而来的语音数据包是不携带类型字段的，为了便于TMF模块可以处理，TMF模块在识别到语音数据包是从窄带端口传来而来的情况下，为语音数据包添加类型字段，且修改包头中类型字段为第一数值，以用于表示是来自于窄带终端的语音数据包。
步骤S506：宽带终端接收并识别该语音数据包，若该语音数据包的包头中类型字段为第一数值，则确认是由窄带终端发送的语音数据包，并对该语音数据包的能量振幅执行放大操作，获得放大语音数据包，播放所述 放大语音数据包。
宽带终端在识别窄带终端发送而来的语音数据包之后，为了避免直接播放语音数据包声音较小的问题，对语音数据包的能量振幅执行放大操作，并播放放大语音数据包，从而解决窄带终端呼叫宽带终端时宽带终端侧声音较小的问题。
可以理解的是，宽带终端中预先存储有经过多次试验后确定的放大倍数，宽带终端会按照放大倍数来对能量振幅执行放大操作，从而获得放大语音数据包。
通过上述步骤可以得知本实施例具有以下有益效果：
为了解决窄带终端呼叫宽带终端时宽带终端播放声音较小的问题，在窄带终端呼叫宽带终端的情况下，所述宽带终端接收语音数据包，并对所述语音数据包的能量振幅执行放大操作，获得放大语音数据包，由所述宽带终端播放所述放大语音数据包，从而解决宽带终端播放声音较小的问题。
