Policy Control and Charging
Rule Function Support through Intelligent Policy Control Function (IPCF)
|
Provides the policy
control decision and flow based charging control functionalities for
the subscriber's data traffic in the broadband network.
It performs the decision
based on inputs received from PCEFs/BBERFs, the subscription
profile repository (SSC/SPR), application function (AF),
if available as well as operator’s local policy.
IPCF collates the subscriber
and application data to authorize QoS resources and instructs the
transport plane on how to proceed with the underlying data traffic
in terms of charging and policy.
PCC solution provides
following components:
- Intelligent Policy
Control Function (IPCF)
- Subscriber Service
Controller (SSC)
- Policy Provisioning
