System for providing flexible charging in a network
First Claim
1. A charging system in a packet switched network for charging packets differently dependent on which service flow the packets belong to, the charging system comprising:
- a control system and a serving element associated with a packet forwarding system wherein said control system comprises;
an account function for managing an account of at least one user, anda charging policy decision point for calculating a different charging policy for each of a plurality of allowed services for the at least one user,wherein said serving element comprises;
a token bucket associated with the at least one user, said token bucket for storing reservations for a plurality of service flows received from the account function of the at least one user, anda charging policy enforcement point for performing charging for the plurality of service flows by reducing the stored reservation of the token bucket according to the calculated charging policies.

Abstract
The present invention relates to arrangements for charging in a packet switched network. Packets are charged differently dependent on which service flow the packets belong to. The charging system comprises a control system and a serving element residing in a packet forwarding system wherein said control system comprises an account function adapted to manage an account of at least one user and a charging policy decision point arranged to calculate a charging policy for allowed services for the at least one user. Moreover, said serving element comprises a token bucket per user adapted to store reservations received from the account function of the user associated with the token bucket and a charging policy enforcement point arranged to perform charging for a plurality of the allowed services by reducing the stored reservation of the token bucket according to the calculated charging policy.
