Method, mobile terminal, service platform and system for implementing debit card service

A system for implementing a callback based on debit card service in a mobile device comprising:

• a debit card service platform which is able to obtain a called number called by a mobile terminal, and the mobile terminal containing an automatic dialing function unit, wherein an automatic dialing function of the said automatic dialing function unit is activated and a calling number of the mobile terminal is bound with a debit card, wherein:
• the said mobile terminal containing the automatic dialing function unit is configured in such a way that:
• the automatic dialing function unit dials a preset callback access code before dialing a called number when the said mobile terminal calls the called number so as to trigger the call to the debit card service platform according to the preset callback access code;
• the said debit card service platform is configured in such a way that, upon receiving the call with the preset callback access code, it releases the call, then calls back the said mobile terminal that initializes the call, and then continues the call to the called number according to the obtained called number after the said mobile terminal answers the callback;
• wherein, the said debit card service platform is further configured to, after calling back the mobile terminal, determine whether a binding between the calling number of the mobile terminal and the debit card has been completed, and if it is completed, continue the call to the called number;
• and if the binding is not completed, prompt the mobile terminal to complete the binding.

A debit card service platform which is able to obtain a called number called by a mobile terminal for implementing a callback based on debit card service in a mobile device, comprising:

• a receiving module, a call releasing module, a callback module, a conversation establishment module, and a binding determination module, wherein:
• the said receiving module is configured to receive a call triggered according to a present callback access code prefixing by an automatic dialing function unit contained in the mobile terminal to the called number after the mobile terminal initiates a call to the called number by a user inputting the called number;
• the said call releasing module is configured to release the call after the said receiving module receives the call;
• the said callback module is configured to call back the mobile terminal after the said call releasing module releases the call;
• the said conversation establishment module is configured to continue the call to the called number according to the analyzed obtained called number after the mobile terminal answers the callback;
• and
• the said binding determination module is configured to determine whether a binding between a calling number of the mobile terminal and a debit card is completed, and if the binding is completed, then trigger the conversation establishment module to continue the call to the called number;
• if the binding is not completed, then prompt the mobile terminal to complete the binding.
