Method, Mobile Terminal, Service Platform and System for Implementing Debit Card Service

A system for implementing debit card service based on callback, comprising a debit card service platform, and a mobile terminal containing an automatic dialing function unit, an automatic dialing function of the automatic dialing function unit being activated, and a number corresponding to the mobile terminal being bound with a debit card, wherein:

• the mobile terminal containing the automatic dialing function unit is configured to that:
• the automatic dialing function unit in the mobile terminal dials a preset callback access code before a called number when the mobile terminal calls the called number, and triggers the call to the debit card service platform;
• the debit card service platform is configured to release the call and call back the mobile terminal initiating the call after receiving the call of dialing the preset callback access code;
• continue the called number in the call after the mobile terminal answers the callback;
• and
• therefore, implement the debit card service based on the callback.

A mobile terminal for implementing debit card service, comprising an automatic dialing function unit and a calling unit, wherein:

• the calling unit is configured to:
• initiate a call to a called number after the called number is input by a user;
• the automatic dialing function unit comprises a state module, a setting module and a dialing module, wherein,
• the state module is configured to store state information of automatic dialing function of the automatic dialing function unit, and the state information is expressed as an activated state or a non-activated state;
• the setting module is configured to store a callback access code of debit card service platform;
• and
• the dialing module is configured to, when the state information stored by the state module expresses that the automatic dialing function is in the activated state and when the calling unit initiates the call to the called number, dial the callback access code stored by the setting module before the called number and trigger the call to the debit card service platform.

A debit card service platform for implementing debit card service, comprising a receiving module, a call releasing module, a callback module and a conversation establishment module, wherein:

• the receiving module is configured to receive a call of dialing a callback access code initiated by a mobile terminal containing an automatic dialing function unit, and a number of the call comprises the callback access code and a called number;
• the call releasing module is configured to release the call after the receiving module receives the call;
• the callback module is configured to call back the mobile terminal after the call releasing module releases the call;
• and
• the conversation establishment module is configured to continue the called number in the call after the mobile terminal answers the callback.
