Smooth Evolution of Charging and Policy Related Interfaces from IMS R6 to R7
In order to provide a better solution for flow-based charging and policy control
policy and charging control architecture is proposed based on the integration of policy decision function and charging rule function introduced by IMS R6.Firstly
the control models related to flow based charging and policy control that presented in IMS R6 and policy and charging control architecture are demonstrated briefly. Then interfaces associated with policy and charging control
that is Gx and Rx
are discussed in detail.It is shown that the smooth evolution from IMS R6 to IMS R7 may be implemented by the definitions of specific AVPs.
