Embodiments of the present invention provide a charging method, a charging device, and a charging system. The charging method includes: sending, by an access device, a traffic volume request to a charging device; receiving, by the access device, information about a granted traffic volume that is returned by the charging device according to the traffic volume request; and sending, by the access device, a charging request to the charging device according to usage of the granted traffic volume by the end user, where the charging request carries a parameter indicating linear traffic information, so that the charging device performs charging according to the linear traffic information, where the linear traffic information is a parameter related to each phase of linear traffic generated in a process in which the end user uses the granted traffic volume. According to the technical solutions provided in the embodiments of the present invention, information about each phase of linear traffic generated within a time in which a granted traffic volume is used is reported, so that a charging device can accurately trace traffic usage at a specific time point by a user according to the linear traffic information, thereby enabling accurate charging. |
