Manner and its functioning which strengthen the rating rule of packet data service the manner which is done

摘要

A method for enhancing charging rules in packet data service includes: allocating an identifier for identifying a charging rule and the identifier provided by a CRF is stored by a TPF. The identifier is used to identify the charging rule or a service data flow filter. Therefore, when the CRF provides action indication and identifier for the TPF and the TPF performs a corresponding operation ON the charging rule or ON the service data flow filter according to the identifier. A method for performing modifying operation or installing operation ON the charging rule is also disclosed and which avoids redundant information between the CRF and the TPF and reduces greatly the message flow load between the CRF and the TPF. In addition, a mechanism for the TPF to return operation response to the CRF is also disclosed and so that the CRF can get the status of operations performed by the TPF.
