附图概述 图 1为本实施例中终端结构示意图；
图 2为图 1所示终端进行通话控制的流程图。
本发明的较佳实施方式
下文将结合附图对本发明实施例的技术方案作进一步详细说明。 需要说 明的是， 在不冲突的情况下， 本申请的实施例和实施例中的特征可以任意相 互组合。
实施例 1
本发明的实施例中， 可以在呼叫通话时对耳机和手机之间的蓝牙连接状 态进行检测， 当检测发现断开后可提示用户以及通话对方， 蓝牙耳机已断开。
本实施例提供一种终端， 如图 1所示， 至少包括蓝牙连接检测模块 101、 通话模块 102和播放模块 103。 蓝牙连接检测模块 101设置成：检测耳机与本终端之间的蓝牙连接状态， 如果检测到连接已经断开， 则向通话模块查询当前的通话状态， 如果有通话 存在， 则向播放模块发送提示音播放命令；
其中， 蓝牙连接检测模块 101跟手机相关的蓝牙模块通过接口进行交互 (如图 1所示） ， 交互方式是蓝牙连接检测模块在蓝牙模块注册监听， 注册 成功后， 蓝牙模块会将蓝牙连接断开的状态实时反馈给蓝牙连接检测模块。 蓝牙连接检测模块通过主动查询接口可以从通话模块查询到当前的通话状态 信息。 播放模块接受蓝牙连接检测模块的命令， 二者通过 Request— Response 方式下发命令和返回结果。
通话模块 102设置成： 向蓝牙连接检测模块反馈当前的通话状态； 其中， 上述通话模块 102还和无线网络侧进行交互， 管理终端的呼叫会 话， 包括空口链路的建立与释放、 语音通道的打开与关闭、 向手机其他模块 提供呼叫状态的查询。
播放模块 103设置成： 根据蓝牙连接检测模块 101发送的提示音播放命 令， 读取第一预置音频文件， 并以外放方式播放第一预置音频文件， 其中， 第一预置音频文件存储有蓝牙耳机已断开的提示音。
可以看出， 上述播放模块 103 以外放方式播放第一预置音频文件， 主要 是提示用户， 当前通话中使用的蓝牙耳机与手机已断开， 以便用户进行后续 操作。
在上述终端的基础上， 可选地， 播放模块 103接收到蓝牙连接检测模块
101 发送的提示音播放命令时， 还可以读取第二预置音频文件， 并通过语音 通道向通话对端发送第二预置音频文件， 该第二预置音频文件为蓝牙耳机已 断开的音频文件。 即播放模块 103还可发送蓝牙耳机与终端已断开的提示音 给通话的对方， 以提示对方通话可能有影响。
具体地， 蓝牙连接检测模块 101—旦收到蓝牙模块连接断开的通知后， 就调用主动查询接口获取当前的通话状态， 如果有通话存在， 蓝牙连接检测 模块 101就会下发 Request (即为提示音播放命令）给播放模块 103 , 播放模 块 103收到命令后给蓝牙检测模块一个 Response响应， 然后播放模块 103读 取预置文件 1 , 通过编译码器（codec )编解码后由喇叭（speaker )外放出来 提醒用户， 同时， 从手机物理存储空间中读取预置音频文件 2, 并通过 codec 编码后将对应字节流输出到通话模块 102的语音通道中， 再由无线空口传送 给通过对方。
上述过程的具体实现如图 2所示， 包括如下步骤：
步骤 201. 蓝牙连接检测模块在手机蓝牙模块上注册监听；
步骤 202. 当蓝牙耳机与手机之间的蓝牙连接断开后，手机蓝牙模块将此 状态通知给蓝牙连接检测模块；
步骤 203. 蓝牙连接检测模块查询当前通话状态， 如果无通话， 转至步骤 209, 如果有通话存在， 转至步骤 204;
步骤 204. 蓝牙连接检测模块给播放模块下发 Request;
步骤 205. 播放模块收到 Request后，给蓝牙连接模块一个 Response响应； 步骤 206. 播放模块从物理存储区域读取预置文件 2 (即第二预置音频文 件） ， 通过 codec编码后将对应字节流输出到通话模块的语音通道中；
步骤 207. 通话模块通过无线空口链路将语音通道中的字节流传输出去； 步骤 208. 播放模块从物理存储区域读取预置文件 1 (即第一预置音频文 件） ， 通过 codec编解码后交由 speaker外放出来；
步骤 209. 结束
实施例 2
本实施例提供一种通话控制方法， 主要在用户通过蓝牙耳机使用终端正 在通话的情况下， 当由于某些意外因素 (如耳机没电关机、 二者之间的距离超 过限制等)导致蓝牙耳机和手机之间的蓝牙连接断开后， 终端能检测到此情况 的发生， 并通过 Speaker外放第一预置音频文件， 即提示音 "蓝牙耳机已断 开， 请注意" 给用户。 可选地， 还可以将第二预置音频文件通过无线网络的 语音通道播放给通话对端听， 第二预置音频文件的内容可以是 "对方蓝牙耳 机断开了， 请稍等" 。
本实施例提供的通话控制方法， 包括：
终端检测耳机和本终端之间的蓝牙连接状态；
当检测到耳机和本终端之间的蓝牙连接状态为断开， 且终端确定当前有 通话存在， 则述终端以外放方式播放第一预置音频文件， 其中， 第一预置音 频文件存储有蓝牙耳机已断开的提示音。
其中， 终端可通过在手机蓝牙模块上注册监听以检测耳机和本终端之间 的蓝牙连接状态。
而终端以外放方式播放第一预置音频文件的过程包括： 终端从本终端物 理存储空间中读取第一预置音频文件， 并将编译码器编码后的第一预置音频 文件由喇八外放出来。
另外， 可选地， 在检测到耳机和本终端之间的蓝牙连接状态为断开， 且 确定当前有通话存在时，还通过语音通道向通话对端发送第二预置音频文件， 以提示通话对方 "蓝牙耳机已断开" 。 此时， 从手机的物理存储空间中读取 文件字节流， 然后交由手机的编解码器处理， 该方案涉及到两个预置音频文 件， 第一预置音频文件是用于提示用户自身蓝牙连接已断开的音频文件， 该 文件由编解码器处理后直接交由外接 Speaker播放， 第二预置音频文件则是 播放给通话对方听的， 该文件由编码器处理后将编码后的字节流传送到语音 通道中。
从上述实施例可以看出， 本申请技术方案在终端和蓝牙耳机的连接断开 后， 终端自动用 Speaker外放 "蓝牙耳机已断开， 请注意" 之类的提示音提 示用户， 同时将预置的录音文件（录音文件的内容可以是 "对方蓝牙耳机断 开了， 请稍等" ）通过无线网络的语音通道播放给对方听， 提示对方稍作等 待。 既提示了用户自身， 又有利于通话对方了解当前的状况， 极大的提高了 用户体验。
本领域普通技术人员可以理解上述方法中的全部或部分步骤可通过程序 来指令相关硬件完成， 所述程序可以存储于计算机可读存储介质中， 如只读 存储器、 磁盘或光盘等。 可选地， 上述实施例的全部或部分步骤也可以使用 一个或多个集成电路来实现。 相应地， 上述实施例中的一个或多个模块 /单元 可以釆用硬件的形式实现， 也可以釆用软件功能模块的形式实现。 本申请不 限制于任何特定形式的硬件和软件的结合。 以上所述， 仅为本发明的较佳实例而已， 并非用于限定本发明的保护范 围。 凡在本发明的精神和原则之内， 所做的任何修改、 等同替换、 改进等， 均应包含在本发明的保护范围之内。
工业实用性
本申请技术方案在通话过程中终端与蓝牙耳机断开时提示用户， 这样， 有利于通话对方了解当前的状况， 极大的提高了用户体验。 因此本发明具有 虽的工业实用性。
