The microphone 22 is used for recording the sound carrier information 6. The microphone can record the sound carrier information 6. The decoder 23 is configured to decode the recorded sound carrier information 6 to obtain encoded information. The encoded information parsing unit 24 is configured to parse the encoded information obtained by decoding, determine whether the sound carrier information 6 is generated according to a predetermined encoding rule, and if the sound carrier information 6 is generated according to the predetermined encoding rule, the encoded information parsing unit 24 is further configured to extract corresponding service information according to the encoded information. The sending/receiving unit 25 is configured to send information to the backend server 4, and receive a message from the backend server 4 after a success is returned. The transmitting/receiving unit 25 is also configured to transmit a service provision request message to the backend server 4 and receive a service from the backend server 4 if the sound carrier information 6 is generated according to a predetermined encoding rule; the transmitting/receiving unit 25 is also configured to request a message from the server side if the sound carrier information 6 is not generated according to a predetermined encoding rule. The input unit 26 is used for inputting information required to be input by the backend server 4. The display unit 27 is used for displaying the information required to be played by the background server 4.
The coding information analysis unit 24 analyzes the coding information and distinguishes the coding rule of the audio carrier information 6. If the encoding rule of the two-dimensional code 6 is correspondingly consistent with the encoding rule of the background server 4, the sending/receiving unit 25 can communicate with the background server 4 to obtain the desired service. The mobile terminal 2 can decode the voice carrier information 6 of any code system, so that the user of the mobile terminal 2 can more conveniently enjoy the service provided by the voice carrier information 6.
