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...
