The present invention provides a general charging method applicable to a charging system in the communication field, comprising steps of establishing a charging strategy and performing the charging based upon the charging strategy. The charging strategy comprises a plurality of priorities each of which comprises a plurality of periods of time, and each of the periods of time corresponds to a type of rate segmentation and is provided a plurality of rate segments in each of which there are a plurality of rates. The step of performing the charging comprises steps of: searching for the highest priority in the charging strategy; searching for a corresponding period of time in the priority based upon the time a subscriber uses a service, and if found, performing the charging based upon the rate segments in the period of time; when the charging has been completed or the priorities have been searched through, and if there is any usage quantity that can't be charged, recording it and terminating the charging. With such a structure of general charging strategy, the present invention can satisfy various charging demands and provide generality and adequate expansibility. Also, the present invention enables subscribers to configure different charging methods as needed.
