Embodiments of the present invention provide a charging method, an authentication method, a charging device, and an authentication device. The charging method includes: receiving a service unit request sent by an access device, calculating a granted service unit according to a current tariff, determining a reporting time point according to a tariff switch point when it is determined that an overdraft monitoring condition is met according to the granted service unit and a tariff after the tariff switch point, and returning a service unit answer, which carries the granted service unit and the reporting time point, to the access device; and receiving a used service unit reported by the access device at the reporting time point, calculating a remaining service unit based on the granted service unit and the used service unit, and when it is determined that the remaining service unit will cause an overdraft, instructing the access device to perform a forcible offline operation. The technical solutions provided by the embodiments of the present invention may effectively reduce an occurrence probability of a user account overdraft, thereby reducing a loss caused by the user account overdraft to an operator. |
