<p>A method for re-rating a prepaid user is proposed in the present invention. Compared with prior prepaid systems, the present invention introduces new functional entities, i.e. a re-rating management apparatus and an offline charging apparatus, and enhances the existing functional -entity, i.e. the online charging apparatus. The online charging apparatus rates call detail records comprised in an received online charging request to generate rated call detail records, and sends- the rated call detail records to the re-rating management apparatus; periodically backs up account profile, and sends the backed up account profile to the re-rating management apparatus; the re-rating management apparatus triggers re-rating, sends a re-rating request to the offline charging apparatus; the offline charging apparatus generates re-rated call detail records after re-calculating, the call detail records, and sends the re-rated call detail records to the re-rating management apparatus; and the re-rating management apparatus updates account profile in accordance with the re-rated call detail records, and sends the updated account profile to the online charging apparatus. By using the method of the present invention, the re-rating function can be implemented for the prepaid user without affecting the real-time use by the prepaid user, and the problems occurring in the convergence of a prepaid charging system and a postpaid charging system can be solved.</p> |
