Abstract

In this paper, we propose a subscription-based policy control framework that implements a subscription-centered approach for policy control for IP Multimedia Subsystem (IMS), defined by 3rd Generation Partnership Project (3GPP), Release 7. The framework also enables flexible policy definitions based on the subscriber's profile at the application level. In addition, the framework provides functionalities of organizing the subscription data, identifying the policy, stipulating the policy control process, interpreting, managing and enforcing the corresponding policies. The main objective of this framework is to qualify the subscribers and thus, enhance the network customization reflected by the capabilities of defining various flexible policies based on different subscriber policy control requirements.
