Abstract: PURPOSE: A mobile phone message system for allowing a receiver to charge a sender with an origination fee is provided to suppressing spam mails by adding a reception fee to a message origination fee when a sender sends a message to a receiver. CONSTITUTION: A mobile communication provider server(10) transfers a message. A mobile communication provider database(20) stores and manages a charge-free registration number. A sender mobile phone or an SMS server(30) sends a message. A receiver phone(40) or an Internet PC(50) receives the message and registers it. When a sender mobile phone or the SMS server(30) originates a message, it is determined whether a CID(Caller ID) has been registered for free of charge, and the message is marked for 'paid' or 'free of charge' and then sent to the receiver mobile phone(40). If the CID has not been registered, a sender is charged for a reception fee and a receiver is benefited for the reception fee by subtracting it from a mobile phone charge. It is determined whether the receiver reads the message and switch to 'paid' or 'free of charge'. If the receiver wants to switch, a switch signal of a phone number of the sender is transmitted. A free of charge registration office deletes the corresponding number if the number has been registered, or registers it as the 'free of charge' if the number has not been registered. In case of switching from non-registration to registration, reception fee charge and mobile phone fee discount during the non-registration state are canceled.
