附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案,下面将对实施例 或现有技术描述中所需要使用的附图作简单地介绍, 显而易见地, 下面描述中的 附图仅仅是本发明的一些实施例,对于本领域普通技术人员来讲, 在不付出创造 性劳动的前提下, 还可以根据这些附图获得其它的附图。
图 1示出了通用手机蓝牙通话语音框图;
图 2示出了本发明语音分离通话示意图。
具体实施方式
下面将结合本发明实施例中的附图, 对本发明实施例中的技术方案进行清 楚、 完整地描述, 显然, 所描述的实施例仅仅是本发明一部分实施例, 而不是全 部的实施例。基于本发明中的实施例, 本领域普通技术人员在没有作出创造性劳 动前提下所获得的所有其它实施例, 都属于本发明保护的范围。
蓝牙技术是一种无线数据与语音通信的开放性全球规范,它以低成本的近距 离无线连接为基础, 为固定与移动设备通信环境建立一个特别连接。其实质内容 是要建立通用的无线电空中接口 (RadioAir Interface )及其控制软件的公开标 准,使通信和计算机进一步结合, 使不同厂家生产的便携式设备在没有电缆相互 连接的情况下, 能在近距高范围内具有互用、 互操作(Interoperabi l ity) 的性 能。 蓝牙的载频选用在全球都可用的 2. 4GHz ( ISM) 频带, 其收发信机采用跳频 扩谱技 (Frequency Hopping Spread Spectrum), 在 2. 4GHz ISM频带上以 1600 跳 /秒的速率进行跳频。 依据各国的具体情况, 以 2. 4GHz为中心频率, 最多可
以得到 79 个 1MHz 带宽的信道。 在发射带宽为 1MHz 时, 其有效数据速率为 721kbit/s, 并采用低功率时分复用方式发射, 适合 10m范围内的通信。 数据包 在某个载频上的某个时隙内传递, 不同类型的数据 (包括链路管理和控制消息) 占用不同信道, 并通过查询 (Inquiry) 和寻呼 (Paging) 过程来同步跳频频率 和不同蓝牙设备的时钟。除采用跳频扩谱的低功率传输外, 蓝牙还采用鉴权和加 密等措施来提高通信的安全性。
蓝牙协议体系结构采用分层方式,包括蓝牙专用协议和一些通用协议。专用 协议位于协议栈的底部, 从底到上依次是蓝牙无线层 (Bluetooth Radio)、 基带 层 (Baseband)^ LMP (Link Manager Protocol )、 L2CAP层 (Logical link Control and Adaptation Protocol ) SDP层 (Service Discovery Protocol )。另夕卜 RFCOMM 层以 ETSI TS07. 10 为基础, 目的是取代电缆连接; TCS ( Telephony Control Protocol Specification) 以 ITU— T的 Q. 931为基础, 目的是进行呼叫控制。 在蓝牙专用协议之上可以承载 PPP、 TCP / IP、 UDP / IP、 WAP等通用高层协议。
逻辑链路控制与适应协议(L2CAP)位于基带协议层之上, 属于数据链路层, 是一个为高层传输和应用层协议屏蔽基带协议的适配协议。 其完成数据的拆装、 基带与高协议间的适配, 并通过协议复用、分用及重组操作为高层提供数据业务 和分类提取, 它允许高层协议和应用接收或发送长过 64K字节的 L2CAP数据包。 L2CAP在高层和基带层之间作适配, 它与 LMP是并列的, 区别在于 L2CAP向高层 提供负载的传送, 而 LMP不能。 L2CAP向高层提供面向连接的和无连接的数据服 务, 具备多协议复用功能和拆 /装适配功能。
业务搜寻协议(SDP)是极其重要的部分,它是所使用模式的基础。通过 SDP, 可以查询设备信息、业务及业务特征, 并在查询之后建立两个或多个蓝牙设备间 的连接。 SDP支持 3种查询方式: 按业务类别搜寻、 按业务属性搜寻和业务浏览 (Browsing 只有通过 SDP了解通信双方的设备信息、 业务类型、 业务特征, 然后才能在蓝牙设备之间建立通信连接。
蓝牙技术一般而言可以采用全双工或 TDD时分双工, 能同时上 /下行传输数 据,对于带语音通话功能的蓝牙耳机而言, 可以同时获来自便携设备的音频信号 即具有听的功能, 又能将语音信号传输到便携式设备上即具有说的功能。
图 1示出了通用手机蓝牙通话语音框图,其中 GSM模块用于手机与基站间的 蜂窝通信,手机音频模块经由 GSM模块发送和接收语音信号, 实现与其他电话机
的语音通话。 如图 1所示的音频模块位于手机上, 包含麦克风、 扬声器 (听筒) 以及相应的音频处理模块和音频管理模块。蓝牙耳机通过蓝牙耳机上的蓝牙芯片 与手机上相应的蓝牙芯片进行蓝牙连接;通过蓝牙耳机上的蓝牙芯片实现与手机 上的蓝牙芯片的音频上下行传输,并由手机上的蓝牙芯片实现语音信号到音频模 块的连接; 从而音频模块能够实现整个语音通话的控制和管理。
图 2是本申请语音分离通话示意图,在音频模块设置有一分离接口, 通过该 分离接口,语音通话的下行音频即本方听的部分仍通过蓝牙模块传输到蓝牙耳机 上,通过扬声器传入使用者的耳部; 而上行音频即本方说的部分不再由使用者通 过蓝牙耳机的麦克风接收,进而由蓝牙耳机端传到手机的音频模块, 而是由手机 的麦克风接收, 以进行通话。
所述分离接口是在便携式设备的底层音频模块 audio moden中 (位于系统 目录 hardware/libhardware— legacy/audio/), 增加的一个名为 SOURCE— CHANGE 的分离接口, 接口实现内容 (不限于实现方法) 为对音频通道的路径进行切换。 该设置主要是针对安卓操作系统的便携式设备进行的设置,但对于其它类型的便 携式设备也是采用类似的方法, 如苹果操作系统, 设置与音频模块对应的分离接 口, 实现语音切换。
按照蓝牙协议, 当通过 SDP建立通信连接, 可以通过与语音传输相对应的协 议, 进行语音传输。 而本方案中, SOURCE— CHANGE接口用于建立便携式设备与蓝 牙设备在语音的通信过程中的听与说的音频连接,而该接口的工作方法为将音频 连接中的上行部分分离出来并切换至便携式设备的麦克风。即在上下行语音通话 中, 蓝牙设备与便携式设备中涉及到听的部分的线路连接依然有效, 但是, 涉及 到说的部分的语音信号不再是接收蓝牙耳机的麦克风传送来的语音信号,而将来 自便携式设备的麦克风接收到的语音信号, 进而用于语音通话的上行传输。
该分离接口也可以通过已经可编程逻辑器件来实现。
另一个是在便携式设备的上层结构中加入开关模块,功能为判断是否开启语 音通话分离, 并且可以调用上述 SOURCE— CHANGE的接口。所述开关模块可以是独 立的, 也可以是依附于音频模块的附属模块。
上述的便携式设备可以为智能手机、 平板电脑、 PDA等设备。
实现本申请的具体步骤如下:
( 1 ) 当有语音通话发生时, 首先通过开关模块, 来判断是否开启了语音通
话分离; 当开关为打开状态时, 则需要进行音频分离, 否则不予处理。
( 2 ) 在满足步骤 1时, 通过判断模块, 判断当前蓝牙是否处于连接状态, 如果蓝牙耳机设备处于连接状态, 则继续进行操作, 否则不予任何处理。
( 3 ) 当满足步骤 2时, 通过开关模块, 调用分离接口, 实现语音分离; 分 离后, 即可进行语音分离下的蓝牙通话。
语音通话分离功能既可通过硬件方式开启, 也可以通过软件方式开启。便携 式设备上通常具有若干按键, 当通话时, 赋予其中一个按键, 或若干按键的组合 以开启功能。 当用户触发所设按键时, 将开关设为开启状态, 对应开启语音通话 分离功能。在一些实施例中, 用户可以通过触控屏上的软按键触发该功能; 再另 一些实施例中,用户可以通过在通话过程中启动的软件的选择项来实现开启或关 闭功能。
上述功能可以通过中断方式或者循环扫描的方式判断语音通话分离功能是 否开启。
本申请还包括另一实施例, 对于蓝牙耳机而言, 通常具有听说功能, 但是也 存在仅具有听的功能的蓝牙耳机, 或者蓝牙耳机的麦克风效果不好, 或损坏的情 况。 为了进一步提高蓝牙设备的利用效率, 可以通过便携式设备, 预先设定语音 通话分离功能的关闭或开启状态。当用户已知蓝牙设备状态的情况下, 可以提前 在功能设置界面中进行设置。
需要说明的是, 上述装置和系统内的各单元之间的信息交互、执行过程等内 容, 由于与本发明方法实施例基于同一构思, 具体内容可参见本发明方法实施例 中的叙述, 此处不再赘述。
本领域普通技术人员可以理解上述实施例的各种方法中的全部或部分步骤 是可以通过程序来指令相关的硬件来完成,该程序可以存储于一计算机可读存储 介质中, 存储介质可以包括: 只读存储器 (ROM, Read Only Memory), 随机存取 存储器 (RAM, Random Access Memory), 磁盘或光盘等。
以上对本发明实施例所提供的。 一种将便携式设备中语音通话分离的装置, 进行了详细介绍, 本文中应用了具体个例对本发明的原理及实施方式进行了阐 述, 以上实施例的说明只是用于帮助理解本发明的方法及其核心思想; 同时, 对 于本领域的一般技术人员, 依据本发明的思想, 在具体实施方式及应用范围上均 会有改变之处, 综上所述, 本说明书内容不应理解为对本发明的限制。
