Information that makes IVR easier to use and more efficient, extending the capabilities of the IVR business.

The technical solutions of the present application are described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific technical features of the embodiments and the embodiments of the present invention are only illustrative of the technical solutions of the present application, and are not limited, in the case of no conflict. The specific technical features in the embodiments of the present invention and the embodiments may be combined with each other.

FIG. 1 is a flowchart of a method for sending text information according to an embodiment of the present invention, where the method includes:

S101. Acquire text information input by a user when the specified audio signal is detected;

S102. Perform character encoding on the text information to generate a code source that is transmitted to the switch.

S103. Send the code source to a switch.

The method for transmitting text information in the embodiment of the present invention is applied to an IVR system, and the IVR system may include a terminal, a switch, and an IVR service, and the foregoing method is applied to the terminal.

When the user needs to send text information, the terminal dials the IVR access code through the IVR calling software, and the baseband module in the terminal initiates a call to the switch, and the switch triggers the IVR service, and the IVR service generates a play command and a receive command, wherein the play command It is used to instruct the interactive machine to play the specified audio signal on the specified audio link. The specified audio signal here may be a special dual-tone multi-frequency (DTMF) signal with a low frequency of 600 Hz and a high frequency of 1800 Hz superposition. Or use other coding methods for sonic coding.

Of course, the number receiving instruction is used to instruct the switch to receive the code source reported by the terminal.

After the terminal reports the request to the IVR service, the terminal detects whether the specified audio signal is received. If the specified audio signal is received, the terminal enables the text input interface, and obtains the text information input by the user through the text input interface, and the terminal pairs the text. The information is divided and encoded to obtain a DTMF code. The terminal sends the DTMF code to the switch. The switch picks up the DTMF code and converts the DTMF code into a corresponding string. Finally, the switch sends the string to the IVR service. The IVR service will The string is decoded into the text information entered by the user on the terminal.

In the embodiment of the present invention, the process of transmitting text information implemented in the terminal is as shown in FIG. 2, and the audio decoding module on the terminal always samples and analyzes the audio of the call, after the switch plays the specified audio signal, the terminal The audio decoding module immediately detects the specified audio signal and sends a message to the protocol processing module in the terminal.

After the protocol processing module on the terminal receives the message of the audio encoding module, the protocol processing module starts the protocol control process, and then enables the text input interface to obtain the text information input by the user through the text input interface.

After the protocol processing module finishes receiving the text information, the protocol processing module divides the received text information into sub-text information of a specified number of received length according to the length of the received number specified in the IVR service. Here, the specified length of the received number may be Set to 20, that is, the IVR can receive 5 characters at a time, and each character includes 4 DTMF codes. Of course, the length of the receiving number can be adjusted according to the actual situation. The length of the receiving number is not limited in the embodiment of the present invention.

In the process of dividing the text information by the protocol processing module, the protocol processing module encodes each divided sub-text information, thereby obtaining a code source corresponding to each sub-text information, and performing audio modulation on the code source, and The audio modulated code source is sent to the switch.

For example, as shown in Figure 3, the user enters the text "Hello" on the terminal, and the corresponding Unicode code is "4F60597D". Among them, the Unicode code of "you" is 4F60, and the Unicode code of "good" is 597D. Since DTMF encoding does not have E and F, the encoder converts E to *, F to #, and generates DTMF code "4#60597D". The encoding module on the terminal sends the final DTMF code to the baseband module through the operating system of the terminal.

The baseband module converts the DTMF code into an audio signal and inputs it into the audio link. The switch will pick up the DTMF code. The switch will detect and decode the DTMF code one by one. After the switch receives 8 DTMF signals, the switch reports the DTMF code to the IVR service. 4#60597D", the final IVR service will decode the DTMF code as the text message "Hello".

After the DTMF code of the IVR service decoding part is the text information, the playback and the receiving signal are sent to the switch again, and the terminal IVR calling software is notified to send the subsequent text. Since the text message is being sent at this time, the terminal protocol processing module will continue to send the remaining text segments to the encoder module. If the text segment has been sent, the terminal protocol processing module should send an end code to the encoder module, such as "########" in Figure 3. If the length of the character encoding in the last text segment is less than the length of the IVR service once received, it can be sent after the encoding is added with #fill. After the transmission is completed, the IVR service can be restored to the normal IVR self-service mode, the notification is broadcast to the user and the information input by the user through the button is received.

Embodiment 2:

In the embodiment of the present invention, a method for obtaining text information is provided. FIG. 4 is a flowchart of a method for acquiring text information according to an embodiment of the present invention, where the method includes:

S401. Receive a string sent by a switch.

S402. Decode a character string sent by the switch into text information input by the user on the terminal.

As shown in FIG. 4, when the switch receives a request to enable sending of text information, the switch generates a trigger instruction, and the triggering instruction triggers the IVR service to obtain text information.

The IVR service will generate a play command and a receive command, where the play command is set to instruct the switch to play the specified audio signal on the designated audio link, and the receive command is set to instruct the switch to receive the code source reported by the terminal. The IVR service sends a play command and a receive command to the switch.

After receiving the play command and the number receiving command, the switch will play the specified audio signal on the designated link, so that the audio decoding module on the terminal can detect the specified audio signal, and send the text information based on the specified audio signal. The code source generated by the encoding.

Since the interactive machine receives the receiving number command, the interactive machine will receive the code source based on the receiving number command, and the receiving length can be set on the switch. After the switch fills up a set of DTMF codes, the switch converts a set of DTMF codes into strings. The switch sends the string to the IVR service, and the IVR service decodes the received string to obtain partial text information. In the decoding process, the decoder of the IVR service detects whether there is an end code in the string. If there is no end code, the IVR service will continue to issue a play command, so that the terminal continues to report the text information, and the interactive machine fills up a group of DTMFs. After the code, the subsequent string is sent, and the decoder in the IVR service decodes the string to obtain subsequent text information. If the decoder decodes the end code in the subsequent string, the IVR service will end receiving, so The IVR service completes receiving text information from the terminal.

For example, the IVR service instructs the switch to play a specified audio signal, the voice content prompts the user to enter a password, and then the switch plays the specified audio signal.

After the audio decoding module of the user's smart phone IVR calling software detects the specified audio signal, the audio decoding module will inform the protocol processing module 501 that the protocol processing module 501 on the smart phone sends the information to the calling software of the smart phone, thereby making the smart phone Enable the text input interface.

When the user enters a strong password "qeER@123" in the text input interface, the smartphone After obtaining the strong password input by the user, the protocol processing module on the smart phone will split the text. The reason for the splitting here is that the maximum number of digits can be set in the IVR service, so that the protocol processing module on the smart phone needs to put the text. For segmentation, for example, the maximum number of received numbers set on the IVR service is 20, and 5 characters can be received at a time, and 4 DTMF codes are used for each character.

The smartphone divides the user input "qeER@123" into two text segments, "qwER@" and "123". And first send "qwER@".

The encoding module in the smart phone encodes "qwER@" as "00710077004500520040", where "q" is encoded as "0071", "w" is encoded as "0077", "E" is encoded as "0045", and "R" is encoded as "0052", "@" code is "0040". The baseband module sent to the smartphone then performs DTMF tone modulation.

The switch fills the 20-bit DTMF code once and sends it to the IVR service for decoding to obtain the text "qwER@".

The IVR service does not receive the end symbol and continues to instruct the switch to play the specified audio signal.

The audio decoder module in the smartphone notifies the protocol processing module after detecting the specified audio signal.

The protocol processing module in the smartphone continues to send the remaining text "123" to the encoding module.

The encoding module first encodes "123" as "003100320033", where "1" is encoded as "0031", "2" is encoded as "0032", and "3" is encoded as "0033". Then add the terminator to generate the final code "003100320033########". Finally, the baseband module sent to the smart phone performs DTMF tone modulation.

The switch fills the 20-bit DTMF code once and sends it to the IVR service for decoding, and obtains the text "123", and detects the end symbol, and ends the receiving process. Then, the two received texts are merged into "qwER@123" and sent to the relevant network element or program for authentication.

In the embodiment of the present invention, the method for obtaining text information changes the IVR service of the related technology to only support the input mode of the digital password, and supports the transmitted text, which can support strong passwords and protect the user's account security.

Embodiments of the present invention further provide a computer readable storage medium storing computer executable instructions that are implemented when the computer executable instructions are executed.
