The invention discloses a WLAN service system for charging based on the user data flow, and the system includes: a WLAN user equipment, a WLAN access network, a Packet Data Gateway and a charging service unit that generates charging information and is connected with the Packet Data Gateway; the invention also discloses a charging method based on the user data flow, and in this method a Packet Data Gateway takes statistic for the current user data flow to obtain original data flow information that is then transmitted to the charging service unit; having received the original charging related information, the charging service unit generates charging information that is then transferred to a charging system. With this system and method, packet data passing through the Packet Data Gateway can be charged based on the data flow.
