A week ago I posted a short video providing an overview of PCRF (here). A more advanced review of policy management architecture and interfaces with OSS and enforcement elements can be found in an article by Peter Dykes (pictured), Senior Analyst, Informa Telecoms & Media.
In addition to the technical review - the architecture of policy management, how it is implemented (see chart below), and why it is needed (to make more money, in short), Peter provides a viewpoint of the subject, of which the first points are "The implementation of policy control in mobile networks could be a major milestone for operators looking to reconcile the disparity between increasing data traffic volumes and flat data revenues" and "As happened with DPI, once the usefulness of the technology becomes clear, it will no longer be enough to offer a stand-alone policy management product; it will have to come with some sort of front end, such as charging, marketing or traffic management"
See "Policy control: Bridging the gap between rising data traffic and flat revenues" - here.
