PURPOSE: A system and a method for restricting service admission according to a credit level of a user are provided to reduce the occurrence of bad bonds by restricting the subscription and usage of a mobile communication service depending on the credit information of the user. CONSTITUTION: A communication company server(120) compares the credit grade of a corresponding user with a credit limit of a requested service, and the communication server restricts the service subscription of the user according to the comparison result. When a threshold value arrival message is received from a charging server(140), the communication provider server informs a service use stoppage to a corresponding user terminal(100). The charging provider checks over the use fee of the user terminal in real time, and the charging server transmits the critical value reach message to the communication server when the usage fee reaches the credit limit critical value. |
