Method, device and system for realizing character input using communication terminal

Abstract

The method includes steps: receiving dual-tone multifrequency code sent from communication terminal in sequence; based on relation between interval time length of received adjacent dual-tone multifrequency codes and prearranged interval time length to determine dual-tone multifrequency code set; based on dual-tone multifrequency code set to determine corresponding character. The invention also discloses a digit reception device, and application system at network side. Using current communication network and communication terminal, the invention implements inputting characters, and network side carries out receiving and parsing operation. Thus, application at network side can receive information of multiple characters input from user so as to raise flexibility and usability.

Description

technical field [0001] The present invention relates to a communication network, in particular to a method, device and system for transmitting characters input at a communication terminal to a network side device for parsing and receiving through the communication network. Background technique [0002] At present, standard communication terminals, such as various telephone terminals, include the following keys: key "1", key "2", key "3", key "4", key "5", key "6", key " 7", button "8", button "9", button " * ", button "0", button "#"; a total of 12 buttons, for the convenience of description, called standard buttons. Different types of communication terminals may also add other function buttons, such as mute button, redial button, pause Keys etc. In the Interactive Voice Response (Interactive Voice Response, IVR) system of communication network at present, the method for collecting user input information for the most part is Dual Tone Multi-Frequency (DTMF) number collectio...

Problems solved by technology

This has just brought bigger limitation to user's input character, as the user can't input English letter etc. in the prior art

For example, some IVR systems in the present technology sometimes require users to input information such as personal ID numbers through communication terminals, and part ID numbers contain letters, so these IVR systems can only prompt users to use another key (such as " * "key) to replace the letters that need to be input, which obviously causes inaccurate user input information, thus affecting the security of the system and a series of problems
