Description

双音多频信号发送方法及装置 技术领域
本发明涉及信号处理技术领域， 尤指一种带緩冲控制功能的双音多频
( Dual Tone Multi Frequency, DTMF )信号发送方法及装置。 背景技术
现有通信终端 （例如： 手机） 的使用中， 常常会遇到下述问题： 例如： 在使用电话充值服务业务为其他手机充值时， 一般需要输入待 充值的手机号码， 而此时如果待充值的手机号码存储在正在使用电话充值 业务的手机的通讯录（例如： 名片夹） 中， 则用户不能直接调用名片夹中 的待充值的手机号码并直接发送到网络端， 只能是先挂机， 将保存在名片 夹中的手机号码记录下来后， 然后再次拨打充值服务电话， 并在通话过程 中输入要充值的手机号码。 在输入电话号码的过程中， 由于 DTMF字符是 即时向网络侧发送的， 即输入一个字符发送一个字符， 当某个字符输入错 误时， 由于该字符已被发送至网络侧， 因此， 不能对错误内容进行更正， 只能挂机后重新拨打充值服务电话再次输入。
又例如： 在使用电话充值卡给手机充值时， 如果选择电话充值服务， 则在充值过程中一般会要求输入充值卡密码，目前一般是 17位充值卡密码。 而在输入 17位充值卡密码时， 发现其中某一位由于失误而错误输入， 但是 由于 DTMF字符是即时向网络侧发送的， 这时已经不能对错误的内容进行 更正， 唯一的办法也只能挂机后重新拨打充值服务电话， 并更加小心翼翼 地输入 17位充值卡密码， 如果再次输入错误， 则用户仍需挂机重新进行输 入操作。
从上述例举的场景中可以看出： 在类似于电话充值等交互式的控制业 务中， 在业务使用过程， 无法获取并使用终端中存储的信息。 且在业务使 用过程， 经常需要发送一串 DTMF字符 （如手机号码， 银行账号， 充值卡 密码等）， 而目前的 DTMF字符都釆用即时发送的方式， 在输入一个字符后 就立即发送至网络侧， 在发现内容错误输入后， 由于内容已经被即时发送 至网络侧而没有办法进行更正， 导致这次输入只能以失败告终。 当需要输 入的 DTMF字符位数增多时， 输入过程中出现输入错误的概率就会明显增 大， 而错误输入的字符不便修改， 给用户使用带来极大的不便， 使 DTMF 信号输入操作效率低， 且频繁的重复操作也导致系统资源和网络资源的浪 费。 发明内容
有鉴于此， 本发明提供一种双音多频信号发送方法及装置， 用以解决 现有技术中存在 DTMF信号输入过程中修改不便， 操作效率低的问题。

所述根据字符修改命令中携带的字符修改指示信息， 对緩存的所述字 符队列进行修改， 具体包括： 对接收到的字符修改命令进行解析， 若解析 出其中携带的字符修改指示信息为删除所述字符队列中的选定字符时， 确 定所述选定字符在所述字符队列中所处的位置； 删除字符队列中的选定字 符， 并将删除的选定字符所处位置之后的其他字符在所述字符队列中的位 置依次向前移动一个字符位置。
所述根据字符修改命令中携带的字符修改指示信息， 对緩存的所述字 符队列进行修改， 具体包括： 对接收到的字符修改命令进行解析， 若解析 出其中携带的字符修改指示信息为更改所述字符队列中的选定字符时， 确 定所述选定字符在所述字符队列中所处的字符位置； 删除所述字符队列中 位于确定出的字符位置处的所述选定字符， 并将所述字符修改指示信息中 指定的字符存储在确定出的所述字符位置处。
所述根据字符修改命令中携带的字符修改指示信息， 对緩存的所述字 符队列进行修改， 具体包括： 对接收到的字符修改命令进行解析， 若解析 出其中携带的字符修改指示信息为在所述字符队列中插入指定字符时， 确 定所述指定字符在所述字符队列中的待插入位置； 将位于所述待插入位置 及其后面位置的其他字符在所述字符队列中的位置向后移动一个字符位 置， 并在所述待插入位置处插入所述指定字符。

图 1为本发明实施例一中 DTMF信号发送方法的流程示意图； 图 2为本发明实施例二中 DTMF信号发送方法的流程示意图； 图 3为本发明实施例中 DTMF信号发送装置的结构示意图。 具体实施方式
针对现有技术中， DTMF信号只有在通话过程中才能发送， 而发送过 程中存在错误输入时修改不便， 操作效率低的问题， 本发明实施例提供一 种 DTMF信号发送方法， 对输入的 DTMF字符进行緩存， 当输入完成并确 认正确后再发送至网络侧， 在输入过程中输入错误时， 可以及时更改， 而 不必挂机后重新操作。
实施例一
本发明实施例一提供的 DTMF信号发送方法， 其流程如图 1所示， 执 行步骤如下：
步骤 101 : 接收到网络侧发送的输入 DTMF字符的输入指令。
在用户启动类似于电话充值等交互式的控制业务之后， 网络侧需要用 户输入所需的信息， 例如充值卡的密码、 电话号码、 银行账号等， 此时用 户根据网络侧的输入指令， 输入上述信息。
步骤 102: 获取待发送的 DTMF字符并緩存至字符队列中。
获取待发送的 DTMF字符可以是获取用户输入的 DTMF字符，具体为， 根据用户输入， 逐一获取用户输入的待发送的 DTMF字符， 并按照获取的 顺序依次存储到緩冲区中的字符队列中。
获取待发送的 DTMF字符也可以是获取预先存储的 DTMF字符， 具体 为， 从存储设备中获取预先存储的字符串作为待发送的 DTMF字符并按照 字符串的存储顺序緩存至字符队列中。
緩冲区一般分为易失和非易失两种， 内存一般是易失的緩冲区， 而 FLASH存储设备一般是非易失的緩冲区。
例如： 上述在通话过程中緩存的字符队列一般是緩存在内存中的。 而 在非通话过程中预先存储的字符串， 一般是存储在终端的非易失的緩冲区 内， 如 FLASH存储设备等。 例如存储在名片夹中的电话号码就属于在非易 失的緩冲区中保存的字符串， 这种存储形式完全具备检查正确性的条件。 在通话过程中，可以直接获取在非通话过程中保存到 FLASH存储设备中的 字符串， 从 FLASH存储设备的存储中读取至内存进行操作。
步骤 103: 是否接收到字符修改指令， 若接收到字符修改指令， 执行步 骤 104; 若未接收到字符修改指令， 执行步骤 105。
字符修改命令中携带有字符修改指示信息， 字符修改指示信息可以包 括： 删除字符队列中的选定字符、 更改字符队列中的选定字符、 或在字符 队列中插入指定字符等。
步骤 104: 根据字符修改命令中携带的字符修改指示信息，对緩存的字 符队列进行修改。
接收到字符修改指令后， 根据其中携带字符修改指示信息的不同， 执 行不同的修改操作， 例如： 删除字符队列中选定的字符、 更改字符队列中 选定的字符、 或在字符队列中插入指定字符等操作。
步骤 105: 判断是否已緩存全部待发送的 DTMF字符， 若已緩存全部 待发送的 DTMF字符，执行步骤 106, 若未緩存全部待发送的 DTMF字符， 执行步骤 102。
在获取到并緩存一个 DTMF字符后， 判断该字符是否为结束字符， 若 是，则说明字符队列中已緩存了全部的待发送的 DTMF字符，执行步骤 106; 若不是， 则还没有緩存全部的待发送的 DTMF字符， 返回步骤 102。 步骤 106: 按照 DTMF字符在字符队列中的顺序， 向网络侧发送緩存 的字符队列中的 DTMF字符。
对緩冲区中緩存的字符队列中的 DTMF字符进行逐个扫描， 实现按照 存储顺序向网络侧逐一发送緩存的字符队列中的所有 DTMF字符的目的。
在对緩存的字符队列中的 DTMF字符进行发送时， 可以釆用 AT命令 实现， 例如： 针对其中的某个字符为 X, 釆用命令 AT+VTS= "X" 实现发 送字符 X到网络侧 ,对緩冲的字符队列中的 DTMF字符逐个使用上述命令， 直到緩存的字符队列中的 DTMF字符全部发送完毕。
上述步骤 104根据接收到的字符修改命令中携带的不同的字符修改指 示信息， 对緩存的字符队列进行修改。 具体可以包括下列过程：
首先， 对接收到的字符修改命令进行解析；
然后， 根据解析出的字符修改指示信息的不同， 执行不同的操作过程， 以下以删除、 更改和插入三种情况为例进行说明。
( 1 )若解析出字符修改命令中携带的字符修改指示信息为删除字符队 列中的选定字符时， 确定选定字符在字符队列中所处的位置， 然后删除字 符队列中的选定字符， 并将删除的选定字符所处位置之后的其他字符在字 符队列中的位置依次向前移动一个字符位置。 例如： 字符队列 Q中已经存在字符 0123456, 现在要将队列中的字符 4 (选定字符）进行删除的操作步骤如下：
确认字符 4在字符队列 Q中的位置为第五个字符；
将第五个字符位置处的字符删除， 字符队列 Q变成 0123 56;
将第五个字符位置之后的其他字符（字符 56 )依次向前移动一个字符 位置， 则字符队列 Q变成 012356。
( 2 )若解析出字符修改命令中携带的字符修改指示信息为更改字符队 列中的选定字符时， 确定选定字符在字符队列中所处的字符位置； 然后删 除字符队列中位于确定出的字符位置处的选定字符， 并将字符修改指示信 息中指定的字符存储在确定出的字符位置处。
例如： 字符队列 Q 中已经存在字符 0123756, 现要将队列中的字符 7 (选定字符） 更改成字符 4的操作步骤如下：
确认字符 7在字符队列 Q中的位置为第五个字符；
将字符队列 Q中第五个字符位置处的字符 7删除， 则该字符队列 Q变 成 0123 56;
将指定的字符 4插入到字符队列 Q中的第五个位置处， 该字符队列 Q 变成 0123456。
( 3 )若解析出字符修改命令中携带的字符修改指示信息为在字符队列 中插入指定字符时， 确定指定字符在字符队列中的待插入位置； 然后将位 于待插入位置及其后面位置的其他字符在字符队列中的位置向后移动一个 字符位置， 在待插入位置处插入指定字符。
例如： 字符队列 Q中已经存在字符 012356, 现要在字符队列 Q中的字 符 3和字符 5之间插入字符 4的操作步骤如下：
确认字符 4在字符队列 Q中的待插入位置为第五个位置处；
将第五个位置及其后面位置的字符依次向后移动一个字符位置， 字符 队列 Q变成 0123 56;
将指定字符 4緩存到在字符队列 Q中的第五个位置， 字符队列 Q变成 0123456。
实施例二
本发明实施例二提供的 DTMF信号发送方法， 其流程如图 2所示， 执 行步骤如下：
步骤 201： 接收到网络侧发送的输入 DTMF字符的输入指令。
同步骤 101 , 此处不再赘述。
步骤 202: 获取待发送的 DTMF字符并緩存至字符队列中。
同步骤 102, 此处不再赘述。
步骤 203: 是否接收到字符修改指令， 若是， 执行步骤 204; 否则， 执 行步骤 205。
同步骤 103 , 此处不再赘述。
步骤 204: 根据字符修改命令中携带的字符修改指示信息，对緩存的所 述字符队列进行修改。
同步骤 104, 此处不再赘述。
步骤 205: 判断是否已緩存全部待发送的 DTMF字符， 若否， 返回步 骤 202; 若是， 执行步骤 206。
同步骤 105 , 此处不再赘述。
步骤 206: 从緩存的字符队列中读取緩存的 DTMF字符并显示给用户。 由于本申请中在业务操作过程中 （例如通话过程中）， 将待发送的 DTMF 字符緩存在字符队列中， 因此， 可以在向网络侧发送至之前， 将緩 存的字符队列中的字符通过用户设备的显示屏幕回显给用户， 以便用户确 认其正确与否。 用户可以通过终端的可编辑环境， 例如拨号界面等， 进行 正确性检查和错误输入的纠正。 步骤 207: 是否接收到用户确认指令， 若是， 则执行步骤 209; 否则， 执行步骤 208。
步骤 208: 是否接收到字符修改指令， 若是， 返回执行步骤 204, 若在 设定的时间后既没有接收到用户确认指令也没有接收到字符修改指令， 则 执行步骤 212。
步骤 209: 根据 DTMF信号支持的合法字符集， 检查緩存的字符队列 中的 DTMF字符的合法性， 如果合法， 执行步骤 211 ; 如果不合法， 执行 步骤 210。
较佳的 , 在 AT命令标准协议中 , 对发送 DTMF信号的 AT命令 +VTS 支持的合法字符集进行了限制， 协议中规定该命令所支持的合法字符集为 0-9, #, *, A-D。 因此， 在发送緩存的字符队列中的 DTMF字符之前， 要 对待发送的 DTMF字符进行合法性检查， 避免发送过程中出错。
进行合法性检查的过程主要是逐个扫描緩冲区中緩存的字符队列中的 DTMF字符， 查看是否在 +VTS所支持的合法字符集范围内。
若检查到所緩存的 DTMF字符中存在 DTMF信号支持的合法字符集之 外的其他非法字符， 则执行步骤 210。 若所緩存的 DTMF字符均为 DTMF 信号支持的合法字符集中的字符， 则确认字符队列中的 DTMF字符合法。 此时可以执行步骤 211进行向网络侧发送 DTMF字符的步骤了。
步骤 210:提示用户对检查到的非法字符进行修改，返回执行步骤 208。 当緩存的字符队列中的 DTMF字符中出现 AT命令标准协议中不支持 的字符时， 即有合法字符集之外的字符， 则需要提示用户修改， 并返回执 行步骤 208。
步骤 211 : 按照 DTMF字符在所述字符队列中的顺序， 依次向网络侧 发送緩存的所述字符队列中的 DTMF字符。
步骤 212: 结束当前流程。 上述实施例二中， 步骤 206-步骤 207将緩存的 DTMF字符显示给用户 确认的过程， 与步骤 209检查緩存的字符队列中的 DTMF字符的合法性过 程的执行顺序可以互换。 即在执行完步骤 205且判断已緩存全部待发送的 DTMF字符之后， 执行步骤 209 , 并在执行步骤 209之后执行步骤 206, 在 执行步骤 207并接收到用户确认指令后再执行步骤 211。
根据本发明实施例提供上述 DTMF 信号发送方法， 可以构建一种 DTMF信号发送装置， 该装置可设置在终端设备中， 如图 3所示， 该装置 包括： 緩存模块 10、 修改模块 20、 判断模块 30和发送模块 40。
緩存模块 10,用于接收到网络侧发送的输入 DTMF字符的输入指令时， 获取用户输入的或预先存储的待发送的 DTMF字符并緩存至字符队列中。
较佳的，上述緩存模块 10,具体用于：接收到网络侧发送的输入 DTMF 字符的输入指令时， 逐一获取用户输入的待发送的 DTMF字符， 并按照获 取的顺序依次存储到緩冲区中的字符队列中； 或从存储设备中获取预先存 储的字符串作为待发送的 DTMF字符并按照字符串的存储顺序緩存至字符 队列中。
修改模块 20, 用于当接收到字符修改命令时， 根据字符修改命令中携 带的字符修改指示信息， 对緩存的字符队列进行修改。
较佳的， 上述修改模块 20, 具体可以包括： 解析单元 201和执行单元
202。
