Billing processing method, system and online billing system

Abstract

The invention discloses a charging processing method, comprising the following steps: when a charging processing of a conversion has abnormal changes, an OCS receives the calling record generated by an external network element, which includes the label of the conversion; and re-charging is carried out on the conversion according to the label in the calling record. The invention also discloses a charging processing system and the on-line charging system OSC. In the embodiment of the invention, a calling record is generated only for conversion having abnormal changes, in no need of generating CDR for all conversions, thus saving the processing resources of the external network element and saving disk space for storing the CDS; since the OCS can re-charge for the conversion having abnormal changes, the loss caused by directly drawback of deducted fee and reserved fee is reduced, thus realizing precise charging when a conversion has abnormal changes.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a charging processing method, system and online charging system. Background technique [0002] OCS (Online Charging System, online charging system) uses DDC (Diameter Credit Control, Diameter credit control protocol) to interact with external network elements, such as SCP (Service Control Point, service control point), etc. Perform credit control. During the interaction process of charging information, the external network element sends a CCR (Credit Control Request, credit control request) message to the OCS. The CCR message is divided into CCR Initial (CCR initial message), CCR Update (CCR update message) according to the credit control category. ), CCR Termination (CCR termination message) and CCR Event (CCR event message) four categories. Among them, CCR Initial, CCR Update, and CCR Event all include RSU (Requested Service Unit, request amount) of the external networ...

Problems solved by technology

[0005] Both of the above abnormal conditions will cause OCS to be unable to accurately bill the session

And when the above abnormal situation occurs, the external network element may generate call records of all the sessions that have occurred, wasting the processing resources of the external network element and a large amount of disk space consumed for storing call records; and when the session is abnormal, the OCS usually returns Refund the deducted fee and the last reserved fee of the abnormal session, or only refund the last reserved fee of the abnormal session, because the above two processing methods only perform the operation of refunding the fee, and the session exception usually occurs in one session Before the end of the session, therefore, when the session is abnormal, the billing method of returning all the deducted fees or the last reserved fee is not accurate, and the call charge from the beginning of the session to the time when the abnormality occurs will be lost
