Abstract:
A method and system for processing information based on dual-tone multifrequency, and a receiving terminal are disclosed in the present document. The method includes: a sending terminal establishing a voice call with a receiving terminal; the sending terminal receiving input key information, encoding the key information into dual-tone multifrequency information, and transmitting the dual-tone multifrequency information and voice call audio information to the receiving terminal together; and the receiving terminal decoding and restoring the dual-tone multifrequency information to the key information; determining a type of the key information according to a preset key information judgment policy, and performing corresponding operations according to the key information.
