Description

通信终端及其主叫时播放回铃音的方法 本申请要求于 2005 年 11 月 29 日提交中国专利局、 申请号为 200510110890.2、 发明名称为 "通信终端及其主叫时播放回铃音的方法" 的中国专利申请的优先权， 其全部内容通过引用结合在本申请中。 技术领域
本发明涉及通信技术， 特别涉及通信终端及其主叫时播放回铃音的方 法。
背景技术 在电信技术高速发展的现代社会， 随着用户的需求日益呈现多样化、 个性化， 移动通信系统和固定通信系统的增值业务都不断出现新的项目来 满足用户日益丰富的个性化需求。 例如在移动通信系统的增值业务中出现 了多媒体消息业务（Multimedia Message Services, 简称 " MMS" )、 交互 式语音应答（Interactive Voice Response, 简称 "IVR" )、 语音短信等。 于 是个性化回铃音业务应运而生。 回铃音是一种信号音， 在通信过程中， 主叫用户通过有线或无线电话 用户终端（ User Equipment, 筒称 "UE" )向被叫 UE发起呼叫， 从双方的 UE间建立连接到被叫用户听到振铃并进行响应大约要用去 3到 10秒钟， 在此时间内， 主叫用户可以听到由网络播放的表示呼叫信号正在发送给被 叫 UE的信号音， 这种信号音就被称作回铃音。 根据 UE或交换系统的类 型可以采用各种音频作为回铃音， 但目前普遍采用 "嘟……嘟……，， 的提 示音作为回铃音。 具体实现时从安装在局端交换系统的只读存储器（Read Only Memory, 简称 "ROM" ) 中选出回铃音， 发送给主叫用户。 因此只 要未改变在交换系统的 ROM中的回铃音， 则主叫用户只能听到一种回铃 音。 一般为 "嘟……嘟……，， 的提示音， 比较单调。 随着以手机为主的 UE 日益普及， 用户越来越注重其使用的个性化。 人们在打电话等待接通 时， 不再满足于听到单调且千篇一律的 "嘟……嘟……，， 的回铃提示音， 他们希望听到更具个性化、 更悦耳的音乐。 于是彩铃业务（ Coloring Ring Back Tone, 简称 "CRBT" ) 由此产生。 彩铃业务即个性化回铃音业务， 是在被叫 UE已开始响铃但用户还未接听的过程中， 以音乐代替向主叫用 户播放的普通的回铃音。
CRBT是一项用户作为被叫用户时生效的业务。 具体地说， 就是申请 业务的用户可以通过多种方式设定或管理回送给呼叫自己的用户的回铃 音， 当有用户呼叫该用户时， 主叫用户听到的就不再是单调的 "嘟 ... ... 嘟……，， 的回铃音， 而是由被叫用户在系统中设定的个性化回铃音， 回铃 音可以是一段音乐， 或者是被叫用户自己设定的留言等一些个性化的回铃 音。 这些个性化的回铃音是被叫用户预先设定的， 可以是系统提供的、 也 可以是被叫用户事先通过个性化回铃音业务系统录制的语音文件、 或被叫 用户事先通过网络下载到个性化回铃音业务系统的语音文件。 现有彩铃业 务是通过网络实现的。 在实际应用中， 上述现有技术的方案存在以下问题： 主叫用户对自己 听到的回铃音不能根据个人喜好进行挑选， 只能被迫听被叫用户定制的回 铃音； 回铃音的播放效果时好时不好； 用户可以选择的回铃音种类和数量 十分有限； 被叫用户需对彩铃功能支付相关费用， 增加被叫用户的额外负 担
造成这种情况的主要原因在于， 现有彩铃技术主要是面向被叫用户的 一项业务， 主叫用户对自己听到的回铃音不能根据个人喜好进行挑选， 只 能收听被叫用户定制的回铃音； 被叫用户由于接受电信服务商提供的服 务， 所以需对该项服务支付相关费用， 增加被叫用户额外负担。 并且， 现 有回铃音是通过网络来播放的， 在播放过程中受到网络条件的限制， 播放 的效果不稳定， 时好时不好； 彩铃业务行业集中度很高， 很多网点尚未建 立完善的产品开发和创新机制， 因此彩铃资源不够丰富， 个性化、 差异化 不足， 造成各网点之间的彩铃重复度高； 而且由于彩铃功能由电信服务商 提供， 用户可以选择的回铃音受到服务商提供的铃声的种类和数量的限 制。
发明内容 本发明提供一种通信终端及其主叫时播放回铃音的方法， 使得主叫用 户能定制个性化的回铃音。
根据本发明的一个方面， 一种通信终端主叫时播放回铃音的方法， 包 含以下步骤：
在作为主叫终端发起呼叫时， 所述通信终端关闭语音通道； 在收到来自网絡侧的被叫终端振铃的通知时， 所述主叫终端播放本地 预设的回铃音；
在播放所述回铃音时， 如果收到来自所述网络侧的被叫终端接听或呼 叫超时的通知， 则所述主叫终端打开语音通道。 根据本发明的又一方面， 一种通信终端主叫时播放回铃音的方法， 包 括： 在作为主叫终端发起呼叫时， 所述通信终端关闭语音通道； 在检测到被叫终端振铃时， 所述主叫终端播放本地预设的回铃音； 在播放所述回铃音时， 如果检测到被叫终端接听或呼叫超时， 则所述 主叫终端打开语音通道。 根据本发明的再一方面， 一种通信终端主叫时播放回铃音的方法， 包 括： 在作为主叫终端发起呼叫时， 播放本地预设的回铃音；
在播放所述回铃音时， 如果需要接听语音通道信号， 则对所述播放作 相应处理以使主叫用户正常接听来自语音通道的信号。
根据本发明的另一方面， 一种通信终端， 通过语音通道与网络侧交互 语音信号， 该终端包括呼叫状态检测模块、 声道控制模块、 用于保存预设 回铃音的存储模块和用于播放该存储模块中预设回铃音的播放模块； 所述呼叫状态检测模块用于， 在检测到所在终端发起呼叫时， 触发所 述声道控制模块关闭所述语音通道； 在检测到来自所述网络侧的被叫终端 振铃的通知时， 触发所述播放模块播放所述存储模块中的预设回铃音； 在 检测到来自所述网絡侧的被叫终端接听或呼叫超时的通知时， 触发所述声 道控制模块打开所述语音通道。 根据本发明的另外一方面， 一种通信终端， 通过语音通道与网络侧交 互语音信号， 包括： 呼叫状态检测模块、 用于保存预设回铃音的存储模块 和用于播放该存储模块中预设回铃音的播放模块；
所述呼叫状态检测模块用于， 在检测到所在终端发起呼叫时， 触发所 述播放模块播放所述存储模块中的预设回铃音； 在检测到需要接听语音通 道信号时， 则对所述播放作相应处理以使主叫用户正常接听来自语音通道 的信号。
本发明的实施例利用通信终端播放本地铃声的能力 , 在呼叫发起后播 放本地预设的铃声直至需要接听语音通道信号时， 再重新打开语音通道。 从而， 主叫终端无需被迫听被叫终端定制的回铃音， 可以自行决定所喜欢 的回铃音； 而且由于主叫终端自行定制的回铃音是通过该终端自身的扩音 器声道播放的本地铃声， 因此， 既无需为彩铃功能的增值服务向网络运营 商支付额外的费用， 减少了移动终端用户的负担； 又可以避免回铃音的质 量受网络的影响， 提高了稳定性。

其中， 所述播放模块 140包括： 查找模块 141 , 用于根据被叫号码或 被叫号码所在群组查找所述存储模块 130 中的对应关系； 播放执行模块 142, 用于播放所述查找单元 141查找到的回铃音。
所述呼叫状态检测模块 110包括： 检测模块 111 , 用于检测呼叫过程 中各种与状态变迁相关的事件； 声道控制模块接口 112, 用于根据所述检 测模块 11检测到的事件向声道控制模块 120发送打开或关闭语音通道的 指令； 播放模块接口 113， 用于根据所述检测模块 111检测到的事件向播 放模块 140发送开始播放或结束播放回铃音的指令。 在具体实现时， 所述检测模块 111可以为网络侧通知处理模块， 根据 来自网络侧的通知确定呼叫过程的状态。 请参阅图 3 , 图 3是本发明第一实施方式的方法的流程图。 本实施方 式中的通信终端是以无线方式接入网络侧的， 例如通信终端为手机。 如图 2所示， 在步骤 210中， 主叫终端发起呼叫时， 关闭语音通道。 具体实现时， 可以是呼叫状态检测模块在检测到主叫终端向被叫终端 发起呼叫时， 触发声道控制模块， 声道控制模块自主关闭语音通道并启动 扩音器声道。 随后， 主叫终端等待通信双方建立连接， 呼叫状态检测模块通过接收 网络侧发出的信号判断通信双方是否建立连接， 如果连接已建立则进入步 骤 220。 在步骤 220中， 主叫终端接收到被叫终端振铃通知时， 播放本地预设 回铃音。 具体实现时， 可以是主叫终端的呼叫状态检测模块通过检测， 接收网 络侧的被叫终端振铃通知， 收到被叫终端振铃通知则表明被叫终端开始响 铃， 主叫终端的呼叫状态检测模块触发用于播放预设回铃音的播放模块。 为实现本发明的实施方式， 用户需对主叫终端的本地铃声进行预设， 可以为不同被叫号码或其所在群组设置不同回铃音。 例如， 对主叫终端中 的不同被叫号码，可单独为其设置一回钤音；或将被叫号码加入某一群组， 为该群组设置一回铃音。 例如有一被叫号码 13********* , 用户可为其设 置回铃音 1 ; 也可将该被叫号码加入某一群组， 如好友群组， 再为该群组 设置一回铃音， 如回铃音 2。 通过配合移动终端的群組功能， 可以实现呼 叫不同的号码有不同的回铃音， 为用户提供了更大的个性化空间。 当然， 也可以不对号码或群组进行分类， 在本地预设一个统一的个性化回铃音。 播放模块根据用户的预设置在存储模块中查找被叫号码或被叫号码 所在群组与预设本地回铃音的对应关系， 按查找结果通过扩音器声道播放 相应的预设回铃音。 例如群组 1对应回铃音 1 , 群组 2对应回铃音 2, 群 组 3对应回铃音 3 , ……用户可以自主选择个性化的音乐， 解决主叫用户 的被动问题。 也就是说， 本发明的实施方式中， 呼叫状态检测模块在触发播放模块 后， 由播放模块通过被叫号码或其所在群组， 例如被叫号码在群组 2中， 则查找到对应的回铃音 2, 再按查找结果通过扩音器声道播放回铃音 2。 回铃音 2可以是和弦铃声、 MP3铃声、 或 AC3格式铃声， 其种类比较丰 富， 能满足广大用户喜好， 而且， 回铃音 2通过扩音器声道在本地播放， 音质好而且稳定， 用户亦无需交纳任何费用。 接着进入步骤 230, 主叫终端判断被叫用户是否摔听电话。 具体实现时， 可以是在播放回铃音的过程中， 主叫终端呼叫状态检测 模块通过检测， 判断被叫终端是否接听电话。 如果呼叫状态检测模块收到 来自网络侧的被叫终端接听通知， 即表明被叫终端处于接听状态， 则进入 步骤 240。 如果呼叫状态检测模块未收到被叫终端接听通知， 即表明被叫 用户可能不在或暂时无法接听， 则进入步骤 250。 在步骤 240中， 主叫终端打开语音通道， 使通信双方开始通话。 具体实现时， 可以是主叫终端呼叫状态检测模块触发播放模块和声道 控制模块， 播放模块停止播放回铃音， 声道控制模块关闭扩音器声道， 打 开语音通道， 使主叫终端通过语音通道与被叫终端进行通话。 直至通话完 毕， 结束本次呼叫。 在步骤 250中， 主叫终端判断呼叫是否超时。 具体实现时， 由于在步驟 230中， 呼叫状态检测模块未收到网络侧的 被叫终端接听通知， 则主叫终端呼叫状态检测模块继续检测来自网络侧的 通信状态。 如果呼叫状态检测模块未收到被叫终端超时通知， 也就是该呼 叫尚未超时， 则返回步骤 230， 继续等待与被叫终端进行通话。 如果呼叫 状态检测模块收到被叫终端超时通知， 也就是该呼叫已超时， 则进入步骤 260。 在步驟 260中， 主叫终端打开语音通道， 接受超时提示音。 具体实现时， 可以是主叫终端呼叫状态检测模块触发播放模块， 播放 模块停止播放回铃音， 并触发声道控制模块打开语音通道， 主叫终端通过 语音通道播放来自网络侧的呼叫超时通知， 得知被叫终端不在或无法接 听， 结束本次呼叫。 本发明方法的第二实施方式与第一实施方式基本相同， 其区别仅在于 本发明的第二实施方式中通信终端以有线方式接入网络侧， 例如固定电话 机。 当然， 本发明实施方式采用的固定电话机至少应支持设置铃声、 播放 铃声、 声道切换和呼叫状态检测等功能。 该第二实施方式中， 主叫终端发起呼叫， 并关闭语音通道。 在建立连 接后， 接收来自网络侧的被叫终端振铃通知， 根据被叫号码或其所在群组 播放相应本地预设回铃音。 呼叫状态检测模块判断是否接收到网络侧的被 叫终端接听通知， 如接收到则打开语音通道， 与被叫终端进行通话； 如果 没接收到则判断连接是否超时， 如未超时则回到上一步继续等待接收被叫 终端接听通知； 如果超时则打开语音通道， 接收来自网络侧的呼叫超时提 示音。 本发明方法的第三实施方式与第二实施方式基本相同， 其区别仅在于 本发明的第三实施方式中主叫终端以无线方式接入网络侧， 而所述被叫终 端以有线方式接入所述网絡侧， 例如主叫终端为手机， 被叫终端是固定电 话机。 本发明方法的第四实施方式与第三实施方式基本相同， 其区别仅在于 本发明的第四实施方式中所述主叫终端以有线方式接入所述网络侧， 而被 叫终端以无线方式接入网絡侧， 例如主叫终端为固定电话机， 被叫终端是 手机。 请参阅图 4, 本发明的通信终端的另一实施例中， 通过语音通道与网 络侧交互语音信号。 该实施例的通信终端包括： 呼叫状态检测模块 410、 用于保存预设回铃音的存储模块 420和用于播放该存储模块 420中预设回 铃音的播放模块 430。
工作时， 所述呼叫状态检测模块 410在检测到所在终端发起呼叫时， 触发所述播放模块 430播放所述存储模块 420中的预设回铃音； 在检测到 需要接听语音通道信号时， 则对所述播放作相应处理以使主叫用户正常接 听来自语音通道的信号。 在一种具体实现中， 所述呼叫状态检测模块 410包括：检测模块 411 , 用于检测所在终端发起呼叫、检测被叫终端接听或呼叫超时的事件或者检 测用户需要接听语音通道的选择； 播放处理模块 412, 用于在所述检测模块 411检测到所在终端发起呼 叫时， 通知播放模块 430播放回铃音； 在所述检测模块 411检测到被叫终 端接听或呼叫超时或者检测到用户需要接听语音通道的选择时 , 通知播放 模块 430停止播放回铃音或者发出屏蔽回铃音、或调节回铃音音量的通知。 请参阅图 5 , 是本发明的另一实施例的通信终端主叫时播放回铃音的 方法的流程图。 步骤 510, 在作为主叫终端发起呼叫时， 播放本地预设的回铃音； 步骤 520， 在播放所述回铃音时， 如果需要接听语音通道信号， 则对 所述播放作相应处理以使主叫用户正常接听来自语音通道的信号。 其中， 所述步骤 520中， 需要接听语音通道的信号是指： 检测到被叫 终端接听或呼叫超时， 或收到来自所述网络侧的被叫终端接听或呼叫超时 的通知时， 或者根据用户选择判断需要接听语音通道。 所述播放本地预设的回铃音是通过扩音器声道播放。 所述相应处理以使主叫用户正常接听来自语音通道的信号进一步指： 停止播放、屏蔽所述回铃音或调节所述回铃音的音量大小使用户能正常接 听来自语音通道的信号。
虽然通过参照本发明的某些优选实施方式， 已经对本发明进行了图示 和描述， 但本领域的普通技术人员应该明白， 可以在形式上和细节上对其 作各种改变， 而不偏离本发明的精神和范围。
