Description

提示音播放方法及装置、 提示音播放控制方法及装置 技术领域
本发明涉及通讯领域, 尤其涉及提示音播放方法及装置、 提示音播放控 制方法及装置。
背景技术
如图 1所示, 为相关技术中媒体服务器所在的组网图。 其中, 媒体服务 器 l l(Media Server , 简称 MS)是软交换体系中提供专用媒体资源功能的独 立设备, 也是分组网络中的重要设备, 提供基本和增强业务中的媒体处理功 能, 包括 DTMF信号的釆集与解码、信号音的产生与发送、 录音通知的发送、 会议、 不同编解码算法间的转换等各种资源功能以及通信功能和管理维护功 能。
软交换 12 ( Softswitch, 简称 SS )是电路交换网向分组网演进的核心设 备, 也是下一代电信网络的重要设备之一, 它独立于底层承载协议, 主要完 成呼叫控制、 媒体网关接入控制、 资源分配、 协议处理、 路由、 认证、 计费 等主要功能, 并可以向用户提供现有电路交换机所能提供的业务以及多样化 的第三方业务。
应用服务器 13(Application Server, 简称 APP)负责各种增值业务和智能业 务的逻辑产生和管理, 并且还提供各种开放的 API(Application Programming Interface,应用程序编程接口), 为第三方业务的开发提供创作平台。 应用服务 器是一个独立的组件, 与控制层的软交换无关, 从而实现了业务与呼叫控制 的分离, 有利于新业务的引入, 本组网中 APP 分为 VIG ( Video Internet Gateway )业务功能和视频业务功能。
媒体网关 14将一种网络中的媒体转换成另一种网络所要求的媒体格式。 例如: 媒体网关能够在电路交换网的承载通道和分组网的媒体流之间进行转 换,可以处理音频、 视频或者 T.120, 也可以具备处理这三者的任意组合的能 力,能够进行全双工的媒体翻译,可以演示视频 /音频消息, 实现其它 IVR ( Interactive Voice Response, 即互动式语音应答 )功能,也可以进行媒体会议 等。
媒体服务器 11与应用服务器 13、软交换 12之间通过 SIP( Session Initiation Protocol,一个应用层的信令控制协议) /H.248/MGCP ( Media Gateway Control Protocol,媒体网关控制协议 )通信, 与媒体网关 14之间通过 RTP ( Real-time Transport Protocol, 实时传输协议 )通信, 软交换 12与媒体网关 14之间通过 SIP/H.248/MGCP通信, 应用服务器 13与软交换 12之间通过 SIP通信。
MSML(Media Server Markup Language,媒体会话标己语言 )/MOML(Media Objects Markup Language,媒体对象标记语言)是开放式的协议, 遵循 SIP的扩 展原则, 在没有改变 SIP协议的基础上, 提供了一个很好的扩展框架用于扩 展的需要。 MSML/MOML是通过 SIP协议的 INFO和 INVITE消息体起作用 的。 SIP/MSML/MOML的组合, 是利用 SIP协议来建立会话、 修改会话、 删 除会话。 而基于 XML ( Extensible Markup Language, 可扩展标记语言) 的 MSML/MOML则用来提供媒体处理的控制接口。 其中 MSML是控制媒体流 和媒体服务器的内部会议资源的接口; MOML是用来控制媒体流和会议中涉 及到的复杂的媒体处理对象的。 SIP和 MSML/MOML组合在一起就构成了一 个应用服务器和媒体服务器交互的一个功能强大的接口框架。

图 2为本发明一实施例提供的提示音播放方法的流程图, 该方法应用于 提示音播放装置, 如图 2所示, 该方法包括如下流程:
S201、 接收应用服务器下发的提示音播放控制信息。
优选的, 提示音播放控制信息包括计算起点、 播放时间粒度信息, 以及 一个或多个具有播放次序的提示音的标识信息; 或者, 包括播放时间点信息, 以及一个或多个具有播放次序的提示音的标识信息。
播放时间粒度信息指的是在录音过程中,播放提示音的间隔时长, 例如, 播放时间粒度信息为 5分钟, 表示在录音过程中, 每隔 5分钟播放一次提示 音, 如果录音持续 11分钟, 那么在第 5分钟和第 10分钟这两个时间点上, 各播放一次提示音。
播放时间粒度信息加上计算起点可以计算出播放时间点信息。 计算起点 可以是录音开启的时间点。
如果提示音播放控制信息中包括一个提示音的标识信息, 则表示在根据 录音开启时间和播放时间粒度信息计算出的各个播放时间点上, 播放同一个 提示音。 如果提示音播放控制信息中包括多个具有播放次序的提示音的标识 信息, 则表示在各个播放时间点上, 依次播放各个提示音, 在一次录音过程 中, 各播放时间点上播放的提示音可以相同或不同。 提示音可以预先存储在 提示音播放中。
基于应用服务器与媒体服务器之间的 SIP协议, 优选的, 应用服务器可 以将提示音播放控制信息添加在需要在录音前下发的录音(record )信令中, 或添加在录音过程中下发的放音( play )信令中, 通过下发录音信令或放音信 令实现对的提示音播放控制信息随同下发, 媒体服务器接收录音信令或者放 音信令后, 再从其 INFO信息中提取提示音播放控制信息。 现有技术中, 录 音指令主要用于开启录音功能, 放音信令主要用于开启放音功能, 通过将提 示音播放控制信息添加到录音指令或放音指令中一同下发, 简化了操作, 避 免了信息的频繁交互。
录音信令或者放音信令的 INFO信息中添加提示音播放控制信息的方式 包括但不局限于在 INFO信息中的挂机定时( SuspendTime )扩充字段中添加 提示音播放控制信息, 相应地, 媒体服务器从 INFO信息中的 SuspendTime 扩充字段中提取提示音播放控制信息。
S202、在录音过程中,根据所述提示音播放控制信息播放预设的提示音。 提示音主要用于向用户提示录音信息, 例如通过语音的形式向用户提示已持 续录音的时长、 剩余电量、 剩余电量能维持录音的时长、 剩余存储容量等信 息。
优选的, 步骤 S202包括:
S202a、从所述提示音播放控制信息中获取播放时间点信息, 以及各播放 时间点上待播放的提示音的标识信息;
若提示音播放控制信息包括计算起点、 播放时间粒度信息, 以及一个或 多个具有播放次序的提示音的标识信息; 则可以根据计算起点和播放时间粒 度信息计算播放时间点信息。 若提示音播放控制信息包括播放时间点信息 , 以及一个或多个具有播放次序的提示音的标识信息, 则可直接从提示音播放 控制信息中获取播放时间点信息。
S202b、在播放时间点来临前,根据该播放时间点上待播放的提示音的标 识信息找到相应的提示音;
S202c、 在播放时间点来临时, 播放相应的提示音。
通过上述步骤 S202a、 S202b和 S202c, 能够实现对提示音的播放时间点 的具体控制, 更加人性化。
图 3为本发明一实施例提供的提示音播放控制方法的流程图, 该方法应 用于提示音播放控制装置, 如图 3所示, 该方法包括如下流程:
5301、 设定提示音播放控制信息;
可以由用户在应用服务器上设置计算起点、 播放时间粒度信息、 一个或 多个具有播放次序的提示音的标识信息, 由这些信息组成提示音播放控制信 息。 或者, 由用户在应用服务器上设定播放时间点信息, 以及一个或多个具 有播放次序的提示音的标识信息, 由这些信息组成提示音播放控制信息。
基于应用服务器与媒体服务器之间的 SIP协议, 优选的, 应用服务器可 以将提示音播放控制信息添加在录音信令中, 在录音前下发所述录音信令至 媒体服务器, 或添加在放音信令中, 在录音过程中下发所述放音信令至媒体 服务器; 媒体服务器接收录音信令或者放音信令后, 再从其 INFO信息中提 取提示音播放控制信息。
录音信令或者放音信令的 INFO信息中添加提示音播放控制信息的方式 包括但不局限于在 INFO信息中的 SuspendTime扩充字段中添加提示音播放 控制信息,相应地,媒体服务器从 INFO信息中的 SuspendTime扩充字段中提 取提示音播放控制信息。
5302、 将所述提示音播放控制信息下发至媒体服务器, 所述提示音播放 控制信息用于媒体服务器在录音过程中播放提示音。
