Abstract

本发明提供一种通话过程中信息的传送方法、获取方法、装置及终端，涉及通信技术领域。其中，该传送方法包括：获取通话过程中要发送的信息对应的ASCII码的二进制序列；根据预设的二进制数的频率和时间，将ASCII码的二进制序列转化成语音信号；将所述语音信号混音到通话语音流中发送给接收方通讯终端。

Description

一种通话过程中信息的传送方法、获取方法、装置及终端 技术领域
本发明涉及通信技术领域，特别涉及一种通话过程中信息的传送方法、获取方法、装置及终端。
背景技术
在目前的移动终端上，当两个用户建立通话后，其中一方想知道对方熟悉的朋友的联系方式的话，如果对方能够记住联系方式的话，这时候用户只能将通话应用程序挂起到后台，然后用短消息的传统方式，或者使用QQ，微信等数据应用来发送，比较费时费力费钱。这些传统方式大多存在一定的网络延时，且运营商需要根据短消息个数或数据流量来收取费用。另外当对方想要找到你刚发的联系人时，还得查询短消息应用或者其他应用，如果这些应用有比较好的用户体验，添加了按照电话号码或者手机号码来进行联系人添加，还相对方便，如果没有这些功能，对方不得不通过记忆或者找来纸和笔来记录，再在电话薄或通讯录中去添加，这样极大的浪费了时间。虽然现在有一些技术能够通过双音多频DTMF方式在通话中传递电话号码，但是这种技术目前仅限于传递0-9的数字，而无法传送油箱地址，油箱在现在科技社会中所起的作用毋庸置疑，所以通话中传递油箱地址也变得越来越迫切。另外DTMF作为移动电话和固定电话的标准通用协议，一些不法份子经常通过非法途径获取通话录音并解析DTMF信息，非法获取用户的密码等安全信息，目前安全性无法保障。
发明内容
本发明的目的在于提供一种通话过程中信息的传送方法、获取方法、 装置及终端，让人们在通话过程中需要传送信息时，能够实时、快捷、准确的传送和获取。
为了达到上述目的，本发明实施例提供一种通话过程中信息的传送方法，包括：

根据预设的二进制数的频率和时间，将所述ASCII码的二进制序列转化成语音信号；
将所述语音信号混音到通话语音流中发送给接收方通讯终端。
其中，所述获取通话过程中要发送的信息对应的ASCII码的二进制序列，包括：
通过发送方通讯终端的软键盘依次键入通话过程中要发送的信息；
根据ASCII码表格，获取所述通话过程中要发送的信息对应的ASCII码的十进制码；
将所述十进制码转化为对应的ASCII码的二进制序列。

具体实施方式
为使本发明要解决的技术问题、技术方案和优点更加清楚，下面将结合附图及具体实施例进行详细描述。
本发明针对现有技术中通话过程中需传送信息时可通过短信、微信等方式传送，但存在延时的问题；也可通过DTMF方式传送，但该方式仅传递数字且安全性无法保障的问题，提供一种通话过程中信息的传送方法及获取方法中，通过将通话过程中要发送的信息转化成包含ASCII码的二进制序列的语音信号，并混到通话语音流中发送，实现了无需挂断电话，实时传送信息；同时接受方解析上述语音信号，并显示该通话过程中要发送的信息，实现了传送信息的便捷性，极大的增强了用户体验；同时采用ASCII码传送的方法具有安全性高及加密鉴权性等特性，具有较好的应用前景。
ASCII码是基于拉丁字母的一套电脑编码系统。它主要用于显示现代英语和其他西欧语言。它是现今最通用的单字节编码系统，并等同与国际标准ISO/IEC 646。
在计算机中，所有的数据在存储和运算时都要使用二进制数表示(因为计算机用高电平和低电平分别表示1和0)，例如，像a、b、c、d这样的52个字母(包括大写)、以及0、1等数字还有一些常用的符号(例如*、#、@等)在计算机中存储时也要使用二进制数来表示，而具体用哪些二进制数字表示哪个符号，当然每个人都可以约定自己的一套(这就叫编码)，而大家如果要想互相通信而不造成混乱，那么大家就必须使用相同的编码规则，于是美国有关的标准化组织就出台了ASCII编码，同一规定了上述常用符号用哪些二进制数来表示。
美国标准信息交换代码是由美国国家标准学会(American National Standard Institute,ANSI)制定的，标准的单字节字符编码方案，用于基于文本的数据。起始于50年代后期，在1967年定案。它最初是美国国家标准，供不同计算机在相互通信时用作共同遵守的西文字符编码标准，它已被国际标准化组织(International Organization for Standardization,ISO)定为国际标准，称为ISO 646标准。适用于所有拉丁文字字母。
ASCII使用指定的7位或8位二进制数组合来表示128或256种可能的字符。标准ASCII码也叫基础ASCII码，使用7位二进制数来表示所有的大写和小写字母，数字字0到9、标点符号，以及在美式英语中使用的特殊控制字符。其中：
0～31及127(共33个)是控制字符或通信专用字符(其余为可显示字符)，如控制符：LF(换行)、CR(回车)、FF(换页)、DEL(删除)、BS(退格)、BEL(响铃)等；通信专用字符：SOH(文头)、EOT(文尾)、ACK(确认)等；ASCII值为8、9、10和13分别转换为退格、制表、换行和回车字符。它们并没有特定的图形显示，但会依不同的应用程序，而对文本显示有不同的影响。32～126(共95个)是字符(32是空格)，其中48～57为0到9的十个阿拉伯数字；65～90为26个大写英文字母，97～122号 为26个小写英文字母，其余为一些标点符号、运算符号等。
同时还要注意，在标准ASCII中，其最高位(b7)用作奇偶校验位。所谓奇偶校验，是指在代码传送过程中用来检验是否出现错误的一种方法，一般分为奇校验和偶校验两种。奇校验规定：正确的代码一个字节中1的个数必须是奇数，若非奇数，则在最高位b7添1；偶校验规定：正确的代码一个字节中1的个数必须是偶数，若非偶数，则在最高位b7添1。
后128个称为扩展ASCII码。许多基于x86的系统都支持使用扩展(或“高”)ASCII。扩展ASCII码允许将每个字符的第8位用于确定附加的128个特殊符号字符、外来语字母和图形符号。

表1
本发明实施例提供一种通话过程中信息的传送方法，如图1所示，包括：
步骤1，获取通话过程中要发送的信息对应的ASCII码的二进制序列；
步骤2，根据预设的二进制数的频率和时间，将所述ASCII码的二进制序列转化成语音信号；
步骤3，将所述语音信号混音到通话语音流中发送给接收方通讯终端。
本发明一具体实施例中，ASCII码是基于拉丁字母的一套电脑编码系统。它主要用于显示现代英语和其他西欧语言。它是现今最通用的单字节编码系统，并等同于国际标准ISO/IEC 646。本发明的具体实施例中，通话过程中要发送的信息主要包括第三方的联系方式，例如第三方的电话号码、邮箱地址等等。如表1所示，本发明的具体实施例中目前没有使用ASCII码的0-31及127的字段，其他字段的大小写字母、数字以及特殊符号等已经能够满足邮箱地址和电话号码的命名。
可选的，本发明具体实施例中，步骤1包括：
步骤11，通过发送方通讯终端的软键盘依次键入通话过程中要发送的信息；
步骤12，根据ASCII码表格，获取所述通话过程中要发送的信息对应的ASCII码的十进制码；
步骤13，将所述十进制码转化为对应的ASCII码的二进制序列。
本发明一具体实施例中，假如通话中要发送的信息为电话号码13314528888，查找表1的ASCII码表，则对应的ASCII码为十进制49，51，51，49，52，53，50，56，56，56，56；则二进制为：110001，110011，110011，110001，110100，110101，110010，111000，111000，111000，111000。
本发明实施例中，当两个用户建立通话后，其中一方想知道用户熟悉的朋友的联系方式时，一种方法是如果用户已经记住了所需的电话号码或邮箱地址，则仅需在类似输入法的软键盘(因为一般的通话菜单仅仅有拨号盘，仅仅有数字键，不能够满足本申请的发送所有字符和数字的需求)上按照顺序输入电话号码或邮箱地址，则该电话号码或邮箱地址就能够转化为语音信号跟随通话语音流一同发送给接收方，则接收方同样可以准确地接收到用户所发送的联系方式。较佳的，软键盘指QWERTY键盘(全键盘)。
可选的，本发明具体实施例中，步骤1还包括：
步骤14，调用发送方通讯终端的通讯录接口，获取通话过程中要发送的信息；
步骤15，响应所述通话过程中要发送的信息的传送操作，根据ASCII表格，将所述通话过程中要发送的信息转化为对应的ASCII码的十进制码；
步骤16，将所述十进制码转化为对应的ASCII码的二进制序列。
本发明一具体实施例中，当两个用户建立通话后，其中一方想知道用户熟悉的朋友的联系方式时，如果发送方没有记住第三方联系方式，则执行步骤14，调用发送方通讯终端的通讯录接口，查询到对应的通话过程中要发送的信息，即第三方的联系方式，电话号码或邮箱地址。具体的，步骤15中的响应所述通话过程中要发送的信息的传送操作，所述传送操作可以为在联系人目录选中要发送的联系人，操作菜单选项，点击“通过ASCII发送“，即可通过语音通道，即小区站CS域，将联系方式发送给对方。
需要说明的是，点击“通过ASCII发送“后，此时通话过程中要发送的信息将通过内置于发送方通讯终端的模拟键盘输入方式在后台对该信息进行了按键操作，将该信息转化为ASCII码的十进制码；再执行步骤16，将所述十进制码转化为对应的ASCII码的二进制序列。
本发明一具体实施例中，步骤2包括：
步骤21，分别预设二进制数1和二进制数0的频率，以及该二进制数1和二进制数0的预设频率的持续时间；
步骤22，利用Goertzel基本算法对所述ASCII码的二进制序列进行处理，并在预设位置进行音调检测，生成包含ASCII码序列的语音信号。
本发明具体实施例中，生成语音信号使用的算法的基本原理如下：代表二进制数1的频率设定高频1800HZ，代表二进制数0的频率设定为1400HZ。代表1或者0的频率分别需要持续时间为22ms，另外对1400HZ或1800HZ的频率幅值也有一定的要求，幅值和时间的要求是由本发明具体实施例规定和限制的，与核心算法息息相关，频率的解析和生成都与此有关。则可以避免受到正常语音信号的干扰造成不必要的误检测。另外每发送一个字符1为起始位，0为终止位。那么在通话过程中发送一个数字或字符的频率时间大约为154ms。
本发明的具体实施例中，使用Goertzel基本算法能得出与常规离散傅立叶变换(DFT)或(快速傅氏变换)FFT相同的频率实部和虚部。如果需要的话，还可以从该频率实部和虚部中计算出幅度和相位信息。Goertzel基本算法是在每次采样后立即进行处理，在每个第N次采样进行一次音调检测。在采用FFT算法时，我们要对成块的采样进行处理，但这并不意味着必须按块来处理数据。数字处理的时间很短，因此如果每次采样都存在一次中断，那么这些数字处理完全可以在中断服务程序(ISR)内完成。或者，如果系统中存在采样缓存，那么可以持续采样，然后进行批处理。
本发明实施例中，由于此Goertzel基本算法产生的信号在时域是模拟的，因此对它的检测需要先采样形成数字信号。从组成此算法的信号的高，低频率组中可以看到其最大频率为1800Hz，此算法所需的1400HZ和1800HZ频率都位于人的可听范围内，在电信应用中普遍采用8kHz的采样率，即每秒8000个采样，根据奈奎斯特采样定律，可以完全满足要求。
下面结合图2，对本发明具体实施例的通话过程中信息的传送方法做具体说明：(假设该通话过程中要传递的信息的第三方的联系方式)
步骤101，甲乙双方建立通话；
步骤102，通话甲方请求通话乙方发送联系人A的联系方式(电话号码和邮箱地址)；
步骤103，判断通话乙方是否记得联系人A的联系方式；
步骤104，若通话乙方记得联系人A的联系方式，则直接调用菜单中专用的软键盘，在软键盘按照顺序输入联系方式号码；
步骤105，若通话乙方不记得联系人A的联系方式，则调用乙方通讯录接口，查询到对应的联系人A，然后在菜单中选中“通过ASCII码发送联系方式”，此时联系人A的联系方式将通过内置的ASCII码编码程序模拟键盘输入方式在后台对联系方式进行按键操作；
步骤106，将代表联系方式的字符和数值的ASCII码频率信号转化为语音信号并混音到发送方向放入PCM语音流中发送给通话甲方。
为了更好的实现上述目的，如图3所示，本发明实施例还提供一种通话过程中信息的获取方法，包括：
步骤4，获取包含ASCII码序列的语音信号；
步骤5，解析所述语音信号，得到通话过程中要发送的信息并在接收方通讯终端的通话界面上显示。
具体的，本发明一具体实施例中，所述获取方法还包括：
步骤6，通过调用所述接收方通讯终端的通讯录接口保存所述通话过程中要发送的信息。
本发明实施例中，当接收方通讯终端正确获取到对端发送的联系方式的握手信号后，开始实时地去检测语音的PCM流中的信息，当语音流中的PCM语音包含的数字或字母信息满足了此算法要求的频率，时间和幅值，则提取其中的号码信息如0-9，*，#，.，@，A-Z，a-z等。并且产生中断，同时给用户进行完整提示，用户可以在通话中进行实时地保存联系人电话号码和手机号码。这种中断的方式比轮训方式大大地节约了系统资源和功耗。这些特性不仅简化了ASCII码信号的解码同时也降低了ASCII码的误检的概率。这样便使得接收端可以检测出按键的信息并可以摈弃语音和噪声的谐波分量。因此语音和噪声被误检为ASCII码信号的概率就大大减小。
本发明的上述实施例中，如图4所示，步骤5包括：
步骤51，分别获取所述语音信号的行频和列频；
步骤52，根据所述语音信号的行频和列频，获取对应的二进制码序列；
步骤53，分别将所述行频和列频的频率和幅值与预设范围进行比较，当所述频率和幅值均在所述预设范围内时，确定该二进制码序列为ASCII码序列；
步骤54，根据所述ASCII码序列，得到对应的通话过程中要发送的信息；
步骤55，将所述通话过程中要发送的信息在接收方通讯终端的通话界面上显示。
承续上例，本发明具体实施例中，在成功建立通话后，在DSP中实时地检测对端是否发送ASCII码信号，当甲方成功收到包含ASCII码音频序列的语音，则马上调用内置的ASCII码解析程序对语音进行解析。内置的ASCII码解析程序寻找信号的行频和列频，只有符合算法的频率和幅值都满 足了要求，才是正确的ASCII码信号，这样有效过滤了一些语音中的谐波干扰。最终解析的结果是连续的0-9的数值或A-Z，a-z，*，@，#等其他字符，然后在通话界面进行提示给甲方，并调用通讯录接口进行提示保存或放弃。
下面结合图5对本发明实施例的通话过程中信息的获取方法作具体说明：
步骤201，通话甲方收到包含ASCII码序列的语音数据；
步骤202，调用通话甲方的DSP内部解码程序对ASCII码数据进行解析；
步骤203，将解析完的完整的电话号码或邮箱地址显示通话甲方的通话界面上；
步骤204，调用通话甲方的通讯录接口进行联系方式保存提示；
步骤205，通话甲方成功保存解析完的联系人A的联系方式。
具体的，假如传递电话号码13314528888，那么对应的ASCII码的十进制为49，51，51，49，52，53，50，56，56，56，56，则二进制为：110001，110011，110011，110001，110100，110101，110010，111000，111000，111000，111000。
假设传递的邮箱地址为wgh@zte.com.cn，那么对应的ASCII码的十进制为119，103，104，64，122，116，101，46，99，111，109，46，99，110，则二进制为1110111(w)，1100111(g)，1101000(h)，1000000(@)，1111010(z)，1110100(t)，1100101(e)，101110(.)，1100011(c)，1101111(o)，1101101(m)，101110(.)，1100011(c)，1101110(n)。
在发送端，ASCII码发送模块将按照代表联系方式的二进制序列，按照算法要求的频率和时间要求产生音频信号，并混音到上行的通话语音流中。在接收端，在收到鉴权信号后，开启ASCII码解析模块的检测算法，对下 行的语音流进行实时检测，首先解析出发送端发送的频率和时间要求满足那一个ASCII码，根据ASCII码查询到对应哪个字符和数字以及等特殊字符，然后根据组合情况决定最终接收到的联系方式，如电话号码和邮箱地址。如果同时传递电话号码和邮箱地址，按照算法会有规定的顺序去发送，两个内容中间会预置一段空白的内容作为分割线，以便正确区分电话号码和邮箱地址。
