A charging control device, method and system. When a UE (112) accesses a service charging an OTT SP, a charging control device (102) receives flow description information from a PCEF (108) (2001), wherein the flow description information is acquired by the PCEF (108) according to a data flow received from the UE (112); a service identifier corresponding to the data flow is determined according to the flow description information (2002); and the service identifier is sent to the PCEF (108), so that the PCEF (108) charges the service according to the service identifier (2003). When the UE (112) accesses the service, the PCEF (108) can acquire the service identifier from the charging control device. In this way, without configuring a service identifier and a charging identifier on a PCEF (108), the PCEF (108) can obtain the service identifier and the charging identifier corresponding to a data flow, so as to reduce the workload of configuration. |
