Claims16
A method for calculating a telecommunication service charge of a user based on a predetermined length of time for which the user uses the telecommunication service, comprising the steps of:
- a) calculating reference time of the user based on telecommunication service use time for a predetermined period;
- b) calculating flat rate application time based on the predetermined additional amount, the flat rate application time being a period during which flat rate is applied after the reference time;
- c) reading the user's telecommunication service subscription time of this month from a database for storing the user's telecommunication service usage history;
- and
- d) imposing a first service charge if the telecommunication service use time of the user is shorter than the reference time, imposing a second service charge if the telecommunication service use time of the user is longer than the reference time and shorter than the flat rate application time, and imposing a third service charge if the telecommunication service use time of the user is longer than the flat rate application time,
- wherein if the user is an updated subscriber for an ith service period, the additional amount is calculated based on an equation as:
