The objective is to study an evolved policy solution through enhancement of 3GPP policy framework. One of the aims of the study is to ensure a policy architecture that provides an extensible framework for easy reuse with new IP based services by identifying areas where improvement of specifications are feasible. The study item will look into solutions for the examples in the section above.

Existing components for consideration in the Policy Study are functions and interfaces to/from
  • PCRF, PCEF and BBERF;
  • SPR, HSS;
  • ANDSF;
  • IMS policy decision making entities.
The study aims to provide a more comprehensive way (e.g. going beyond existing 3GPP PCC framework) to handle operator policies for all IP / service flows (IMS and non-IMS) in a coordinated manner and under varying network conditions while keeping in view aspects such as:
  • user preferences;
  • user subscriptions;
  • service requirements;
  • terminal capabilities (including converged terminals);
  • network capabilities (3GPP and those non 3GPP accesses interworking with 3GPP);
  • Session transfer and terminating policies;
  • Security policy control, e.g. firewalling and gating.
Roaming scenarios are considered as part of this study. Compatibility with existing system architecture elements are protected and backward compatibility is expected. All types of policies i.e. static/pre-provisioned, dynamic, network based, UE based are considered in the study.

When a key issue is resolved sufficiently to be incorporated into the specification in an independent manner, the study work may move forward for a decision for normative specification work on such issue(s) using a new work item or a TEI.
