TECHNICAL FIELD OF THE INVENTION
The present invention relates to a prepaid mobile communication system, and more particularly to a communication system for managing and operating communication time by a mobile communication device such as a mobile phone by a prepaid (prepaid) system.
[0002]
[Prior art]
In recent years, mobile communication devices such as mobile phones have rapidly become widespread. In general, the collection of telephone and communication charges in such a mobile communication device is a post-payment method in which a user / contractor of the mobile communication device is charged for a fixed period of use and collected.
However, such a post-payment method has a disadvantage that if a mobile phone or the like is discarded before the usage fee is paid, the communication carrier cannot collect the usage fee.
[0003]
To solve such a problem, for example, as shown in Japanese Patent No. 3369140, a user of a mobile communication device is required to pay a usage fee as a prepaid amount in advance, and Each time is used, a so-called prepaid system is introduced, in which a usage fee is deducted from the prepaid amount.
[0004]
In addition, when the user pays the usage fee when using another person's mobile phone, or when the employer pays the usage fee when the employee uses the mobile phone owned by the employee, for example, When the owner of the mobile communication device is different from the person who pays the usage fee, a method using a prepaid card has been proposed.
In addition, a free telephone system (a communication system in which a telephone exchange pays for telephone calls and communication charges) is used to access a specific telephone exchange that is cheaper, rather than a telecommunications carrier who has subscribed to a mobile telephone, and the telephone exchange is accessed through the telephone exchange. Communication methods have been proposed, among which prepaid cards are used.
[0005]
As a method of using a prepaid card, for example, as disclosed in Japanese Patent Application Laid-Open No. 2002-64638, a user first purchases a prepaid card at a store such as a convenience store and When using, call the free call access number displayed on the prepaid card, then enter the ID number and PIN displayed on the card, and finally, Make a call by entering a phone number.
[0006]
The prepaid card eliminates the complexity of paying the usage fee and enables various usage forms, so it has high convenience, but also has a free call access number, ID number, PIN code, etc. The input of various information related to the call is complicated, and there are also problems such as changing some or all of these numbers for each prepaid card.
For this reason, an automatic connection device for saving the trouble of inputting such various kinds of information is proposed in Japanese Utility Model Registration No. 3085713.
[0007]
The method of using the automatic connection device is to transfer information written on the prepaid card to a memory provided in the automatic connection device by a dedicated input device separately provided, and insert the automatic connection device into a mobile phone, By transferring the information to the mobile phone, it is possible to save the user from having to input various numbers.
[0008]
However, in the prepaid mobile communication system as described above, when making a call or communication exceeding a preset connection time, the procedure for extending the connection time is complicated, and the convenience of the user is impaired. Has the disadvantage of being
For example, in the case of Japanese Patent No. 3369140, a user brings a mobile phone to a store of a store, communicates with a bank server using a dedicated terminal, and stores an account on the store side and a telephone office. Procedures such as completing electronic payment with the account on the side are required.
For this reason, the store side purchases a dedicated terminal and installs it at the store, which is costly and space-intensive, and the telecommunications carrier such as a telephone office also requires the store's dedicated terminal and the bank. In order to connect the servers, a large-scale network with high security must be constructed, which requires enormous costs.
Also, in the case of Japanese Utility Model Registration No. 3085713, a dedicated input device for writing prepaid card information into the automatic connection device is required.
[0009]
