Evolution of policy control and charging
The present document intends to study the following items:
1) Complete harmonization and merger of the policy control and flow based charging architecture and procedures;
2) Possible architectures and solutions for adding end-user subscription differentiation and general policy control aspects to the policy- and charging control;
3) Alternative solutions for binding bearers to services (provided today by the authorization token). This includes studying solutions for the network to control bearer usage by service flows.
Editors Note: The document may also study the impact on policy control and flow based charging architecture based on the conclusion and approved recommendations of the E2E QoS Work Item in a Release 7 context if deemed feasible.
