Embodiment 1

[0024] The dual-tone multi-frequency signal transmission method provided by Embodiment 1 of the present invention has a process as follows figure 1 As shown, the execution steps are as follows:

[0025] Step S101: receiving an input instruction for inputting DTMF characters sent by the network side.

[0026] After the user starts an interactive control service such as telephone recharge, the network side needs the user to input the required information, such as the password of the recharge card, telephone number, bank card number, etc. At this time, the user enters the above-mentioned information.

[0027] Step S102: Acquiring DTMF characters to be sent and buffering them in the character queue.

[0028] Obtaining the DTMF characters to be sent may be to obtain the DTMF characters input by the user, specifically, according to the user input, obtain the DTMF characters to be sent input by the user one by one, and store them in the in the character queue in the buffer.

Embodiment 2

[0062] The dual-tone multi-frequency signal transmission method provided by Embodiment 2 of the present invention has a process as follows figure 2 As shown, the execution steps are as follows:

[0063] Step S201: receiving an input instruction for inputting DTMF characters from the network side.

[0064] The same as step S101, which will not be repeated here.

[0065] Step S202: Acquiring DTMF characters to be sent and buffering them in the character queue.

[0066] Same as step S102, which will not be repeated here.

[0067] Step S203: Whether a character modification instruction is received.

[0068] Same as step S103, which will not be repeated here.

[0069] If yes, execute step S204; otherwise, execute step S205.

[0070] Step S204: Modify the cached character queue according to the character modification indication information carried in the character modification command.

[0071] Same as step S104, which will not be repeated here.

[0072] Step S205: Determine...

Abstract

The invention discloses a dual-tone multi-frequency signal sending method and a device. The method comprises the following steps: after receiving an input instruction for inputting a dual-tone multi-frequency character sent by a network side, obtaining the dual-tone multi-frequency character to be sent and caching in a character queue; after receiving a character modification command, modifying the cached character queue according to a character modification indicating message carried in the character modification command; and if judging that all dual-tone multi-frequency characters to be sent are cached, sending the dual-tone multi-frequency characters in the cached character queue to the network side according to the order of the dual-tone multi-frequency characters in the character queue. The method solves the problem that the dual-tone multi-frequency character is inconvenient to edit and modify during the use of a service in the prior art and improves the operability of the service and the accuracy of character input.

Description

technical field [0001] The invention relates to the technical field of signal processing, in particular to a dual-tone multi-frequency (Dual Tone Multi Frequency, DTMF) signal sending method and device with a buffer control function. Background technique [0002] In the use of existing communication terminals (such as: mobile phones), the following problems are often encountered: [0003] For example: when using the phone recharge service to recharge other mobile phones, it is generally necessary to input the mobile phone number to be recharged. ), the user cannot directly call the mobile phone number to be recharged in the business card holder and send it directly to the network terminal, but hangs up first, records the mobile phone number saved in the business card folder, and dials the recharge service number again. And enter the mobile phone number to be recharged during the call. In the process of inputting a phone number, since the DTMF characters are sent to the net...
