There is proposed a charging control in which a policy and charging control function provides first (preliminary) charging control information, such as PCC rules, when the communication connection is set up or modified. Then, service information can be retrieved leading to an updated set of charging control information. The policy and charging control function provides then the updated charging control information for enforcement, wherein the charging system is informed about both the preliminary nature of the first charging control information and the validity of the second charging control information for a time before the update, i.e. before the transmission of the second charging control information. The charging system can use this updated charging control information and knows that it has to replace the former charging control information, so that the charging procedure can be corrected accordingly. Thus, charging of a service miming on the communication connection on the basis of correct charging control information is possible over the complete time the service is running.
