Description

语音激活检测控制的方法及其控制设备 技术领域
本发明涉及通信技术领域，特别是涉及语音激活检测控制的方法 及其控制设备。 背景技术
随着增值业务实现技术的快速发展，各种各样的增值业务层出不 穷， 其中的彩铃（个性化回铃音）业务使得主叫用户呼叫被叫时， 在 被叫振铃阶段可以听见被叫用户定制的各种各样的音乐，改变了传统 的主叫用户在等待被叫接听阶段只能听枯燥的回铃声的情况，提升了 用户感受， 因此彩铃业务发展很快。 彩铃业务可以应用于移动网络和 固定网络， 通常通过彩铃播放的内容可以是一段音乐、歌曲或者是小 故事等。
通常来说， 主叫和被叫之间的通话需要通过一段 VOIP ( Voice Over IP, 语音在 IP ( Internet Protocol, 网际协议） 网络上传送）（或 者 VOATM ( Voice Over ATM )语音在 ATM ( Asynchronous Transfer Mode, 异步传输模式） 网络上传送）路径传递， 如果被叫用户申请 了彩铃业务， 则彩铃也需要通过 VOIP (或者 VOATM )路径从被叫 侧传送到主叫侧。 现有技术通常在使用 VOIP (或者 VOATM )路径 时釆用窄带压缩编解码技术对传递的信号进行编解码，为降低窄带编 解码的带宽，在编解码时往往用到 VAD技术。 VAD是一种语音判别 技术， 用户通过电话通话时通常是一种双向交流， 主叫方和被叫方都 平均大致有一半时间是在听，听对方说话时用户没有较强的语音要传 送， 这时编码器检测到的语音信号较弱， 基本都是背景噪音， 编码器 只检测到部分背景声音并对其编码输出，话音信号数据很少因而占用 的带宽就窄， 对背景噪音， 通常可以减少帧传递个数， 因此， VAD 技术可以降低编解码传送带宽并且不会影响话音质量。
在实现本发明的过程中， 发明人发现现有技术至少存在以下问 题： 现有 VAD技术对人声等通常有效， 但对音乐的频谱不能作出有 效的判断， 使得部分音乐没有被当作有效声音传送。 音乐、 歌曲等彩 铃内容通过 VOIP ( VOATM )路径从被叫侧传送到主叫侧时 , 窄带压 缩编解码中的 VAD技术使得音乐效果变差， 因此现有的彩铃的音乐 效果往往效果不理想， 有时候甚至无法听清楚。
发明内容

本发明实施例提供的技术方案是： 由于彩铃业务只在被叫振铃时 播放， 因此， 在回铃音阶段关闭 VAD功能， 使得回铃阶段的彩铃内 容不会因为 VAD技术而受到不利影响， 在通话阶段打开 VAD功能， 利用 VAD技术保证在通话阶段能够有效的降低编解码占用的带宽。
为了使本发明的目的、技术方案及优点更加清楚明白， 以下结合 附图及实施例， 对本发明进行进一步详细说明。 应当理解， 此处所描 述的具体实施例仅仅用以解释本发明， 并不用于限定本发明。
下面以 VOIP设备为例详细说明本发明实施例提供的技术方案的 应用，本发明提供的技术方案也适用于 VOATM和 VOFR ( voice over ATM语音在 ATM上传送& voice over frame relay语音在帧中继上传 送）等类似语音分组传送架构， 本领域技术人员不需要经过创造性劳 动即可实现， 此不赘述。
本发明的一个实施例：
被叫侧 VOIP设备判断本次呼叫回铃音是彩铃， 则可直接在回铃 音阶段关闭 VAD, 并在通话阶段打开 VAD功能。
具体来说， 被叫侧 VOIP设备判断本次呼叫回铃音是否为彩铃的 方法艮多， 例如：
1、 基于被叫用户 "签约数据"， 被叫交换机可以直接判断； 例如： 在 HLR (归属位置寄存器）到 MSC的消息中 SRI-ACK 中携带的彩铃 SS-CODE ( 254 )业务码标志该呼叫为彩铃呼叫。 不排 除使用其他消息获得用户彩铃签约数据。
2、 基于 "业务码 +被叫号码"， 被叫交换机可以直接判断。
例如： MSC 向彩铃平台发起呼叫时， 被叫号码是 "12531+被叫 用户 MSISDN (移动用户国际号码）"， 其中 12531作为前缀示例， 实 际应用应该可配置。 此时， 在 MSC到彩铃平台之间的交换机可以根 据 12531前缀判断是否为彩铃业务。
本实施例的系统结构图如图 1所示，本发明实施例提供的系统包 括主叫用户终端、 主叫交换机、 被叫交换机， 彩铃中心和被叫用户终 端， 其中：
交换机的原理框图如图 2所示 （这里只描述与本发明相关部分， 其他部分不体现）， 包括呼叫识别单元、 判断单元和控制单元， 判断 单元用来判断本次呼叫的回铃音是否是彩铃， 当判断单元判断本次呼 叫的回铃音是彩铃时， 指示控制单元关闭呼叫路径中编码器的 VAD 功能，控制单元用来根据判断单元的指示关闭呼叫路径中的编码器的 VAD 功能； 识别单元用来识别主叫和被叫是否处于通话阶段， 当识 别单元识别主叫和被叫处于通话阶段时，指示控制单元开启呼叫路径 中编码器的 VAD功能， 控制单元用来根据识别单元的指示开启呼叫 路径中的编码器的 VAD功能。
本实施例的流程图如图 3 所示， 具体包括如下的步骤（以 SS7 信令为例）：
步骤 S301、 主叫交换机根据主叫用户终端的呼叫请求向被叫交 换机发送 IAM ( Initial Address Message, 初始地址消息）；
步骤 S302、 被叫交换机向主叫交换机响应 ACM ( Address Complete Message, 地址全消息）；
步骤 S303、 被叫交换机收到 IAM消息后， 根据被叫用户的签约 数据或者本次呼叫的业务码和被叫号码判断被叫用户是否签署了彩 铃业务， 如果是， 转步骤 S304, 否则转步骤 S306;
步骤 S304、 被叫交换机关闭呼叫路径中编码器的 VAD功能， 向 主叫播放彩铃；
步骤 S305、 用户摘机， 被叫交换机向主叫交换机发送 ANM (应 答 ) 消息， 然后执行步骤 S307。
步骤 S306、 被叫交换机向主叫交换机发送 ANM (应答） 消息； 步骤 S307、 主叫用户和被叫用户通话， 同时开启呼叫路径中编 码器的 VAD功能。
根据局间信令不同，具体区分回铃音阶段和通话阶段的信令参数 也不同， 但应用本实施例提供的技术方案的原理基本一致， 这些也是 本领域内人所皆知的。
本实施例中， 判断回铃音是否为彩铃由被叫交换机完成， 但具体 应用本发明实施例提供的技术方案时，由于彩铃业务除了可以由被叫 侧设备实现之外， 在呼叫路径中的其他设备也可以实现， 因此， 对判 断回铃音是否为彩铃并不局限于由被叫交换机完成， 例如， 可以是主 叫交换机，或主叫和被叫之间的一个或者多个其他交换机或者其他的 设备。
本发明的另一个实施例：
被叫侧 VOIP设备不判断用户是否签署了彩铃业务， VOIP设备 在回铃阶段先关闭呼叫路径中编码器的 VAD功能， 并检测是否收到 了被叫的标准回铃音， 如果收到了被叫侧设备播放的标准回铃音， 说 明没有彩铃， 则自动打开呼叫路径中编码器的 VAD功能； 如果没有 检测到标准回铃音， 说明是彩铃， 则在通话阶段才打开呼叫路径中编 码器的 VAD功能。 由于每个国家的标准回铃音都是特定频率的几种 信号音的组合，因此被叫交换机能够非常容易检测到语音信号是否为 标准回铃音。
本实施例的系统结构图如图 1所示，本发明实施例提供的系统包 括主叫用户终端、 主叫交换机、 被叫交换机， 彩铃中心和被叫用户终 端， 其中：
被叫交换机的原理框图如图 4所示， 包括呼叫识别单元、控制单 元和检测单元，检测单元用来检测本次呼叫的回铃音是否为标准回铃 音并将检测结果传送到控制单元，控制单元根据检测单元传送的判断 结果决定对呼叫路径中编码器的 VAD功能的开启和关闭， 识别单元 用来识别主叫和被叫处在回铃阶段还是通话阶段， 当识别单元识别主 叫和被叫处于回铃阶段时，控制单元先关闭呼叫路径中的 VAD功能， 检测单元开始检测，如果检测单元检测到本次呼叫的回铃音不是标准 回铃音， 控制单元一直到通话阶段才开启呼叫路径中编码器的 VAD 功能； 如果检测单元检测到本次呼叫的回铃音是标准回铃音， 则控制 单元直接将呼叫路径中编码器的 VAD功能开启。 本实施例流程图如图 5所示， 具体包括如下步骤： 步骤 S501、 主叫交换机根据主叫用户终端的呼叫请求向被叫交 换机发送 IAM (初始地址） 消息；
步骤 S502、 被叫交换机向主叫交换机响应 ACM (地址全消息 ), 关闭呼叫路径中编码器的 VAD功能；
步骤 S503、 被叫交换机收到 IAM消息后， 检测本次呼叫的回铃 音， 如果检测到本次呼叫的回铃音是标准回铃音， 转步骤 S504, 否 则转步骤 S506;
步骤 S504、 开启呼叫路径中编码器的 VAD功能， 被叫交换机向 主叫交换机发送 ANM (应答） 消息；
步骤 S505、 主叫用户和被叫用户通话；
步骤 S506、 被叫交换机向主叫交换机发送 ANM (应答） 消息， 如果呼叫路径中编码器的 VAD功能尚未开启， 被叫交换机开启呼叫 路径中编码器的 VAD功能；
步骤 S507、 主叫用户和被叫用户通话。
当网络中多数用户都没有签署彩铃业务时，这种检测回铃音的方 法是很有效的， 可以节省大量带宽。
本实施例中， 检测回铃音是否为标准回铃音由被叫交换机完成， 但具体应用本发明实施例提供的技术方案时，由于彩铃业务除了可以 由被叫侧设备实现之外，在呼叫路径中的其他设备也可以实现，因此， 对回铃音的检测并不局限于由被叫交换机完成， 例如， 可以是主叫交 换机， 或主叫和被叫之间的一个或者多个其他交换机。
本发明的再一个实施例：
当被叫侧 VOIP设备不判断被叫用户是否申请了彩铃业务时， 并 且不检测是否收到了被叫的回铃声，而是直接关闭其呼叫路径中编码 器的 VAD功能， 同时启动一个可配置的定时器 X, 当定时器 X配置 的时间届满时或者主叫和被叫进入通话状态， 被叫侧 VOIP设备打开 呼叫路径中编码器的 VAD功能， 定时器 X配置的时间可以是该网络 被叫无应答挂机的最长等待时间，或者用户振铃到摘机的平均时长或 用户指定的时间。 本实施例的系统结构图如图 1所示， 本发明实施例 提供的系统包括主叫用户终端、 主叫交换机、 被叫交换机， 彩铃中心 和被叫用户终端， 其中：
被叫交换机的原理框图如图 6所示， 包括控制单元和定时器， 控 制单元在呼叫开始即关闭呼叫路径中编码器的 VAD功能并启动定时 器， 在定时器设定的时间届满时或者主叫和被叫进入通话状态时， 控 制单元开启呼叫路径中编码器的 VAD功能。
本实施例的流程图如图 7所示， 具体包括如下的步骤： 步骤 S701、 主叫交换机根据主叫用户终端的呼叫请求向被叫交 换机发送 IAM (初始地址） 消息；
步骤 S702、被叫交换机向主叫交换机响应 ACM地址全消息， 关 闭呼叫路径中编码器的 VAD功能；
步骤 S703、 被叫交换机收到 IAM消息后， 启动定时器； 步骤 S704、 定时器设定定时时间届满或者主叫和被叫进入通话 状态， 开启呼叫路径中编码器的 VAD功能；
步骤 S705、 被叫交换机向主叫交换机发送 ANM (应答） 消息； 步骤 S706、 主叫用户和被叫用户通话。
具体应用发明方案时，定时器设置的时间届满可能发生在被叫交 换机向主叫交换机发送 ANM (应答） 消息之前， 也可能发生在被叫 交换机向主叫交换机发送 ANM (应答） 消息之后， 取决于定时器设 置的时间长短以及被叫从响铃到应答的时间。
如上所述的，本发明实施例提供的技术方案通过对呼叫路径中编 码器的 VAD功能的分阶段控制： 在回铃音阶段关闭 VAD功能、在通 话阶段开启 VAD功能， 实现了在传送彩铃音时不会受 VAD影响，在 传送通话语音时尽可能占用少的带宽的目的，满足了彩铃业务传送时 对音乐效果的要求， 同时不会过多占用带宽。
本领域普通技术人员可以理解实现上述实施例方法中的全部或 部分流程， 是可以通过计算机程序来指令相关的硬件来完成， 所述的 程序可存储于一计算机可读取存储介质中， 该程序在执行时， 可包括 如上述各方法的实施例的流程。 其中， 所述的存储介质可为磁碟、 光 盘、 只读存储记忆体（Read-Only Memory, ROM )或随机存储记忆 体 ( Random Access Memory, RAM )等。
以上所述仅为本发明的较佳实施例而已， 并不用以限制本发明， 凡在本发明的精神和原则之内所作的任何修改、 等同替换和改进等 , 均应包含在本发明的保护范围之内。
