Understanding PCEF Profiles
A policy and charging enforcement function (PCEF) profile defines whether policy and charging control (PCC) rules for a Service Control Gateway subscriber are under static control, under dynamic control of the policy and charging rules function, or under activation/deactivation control of a RADIUS server by using the static-policy-control, dynamic-policy-control, or aaa-policy-control statement, respectively, in the PCEF profile configuration. The PCEF profile also identifies the predefined PCC rules and rulebases that the subscriber can use, and assigns a precedence value to each predefined rule. A Service Control Gateway subscriber is assigned a PCEF profile during the subscriber session setup.
A PCEF profile with dynamic policy control requires a Diameter Gx profile, which provides network access information for the Diameter application.
A PCEF profile with RADIUS server control requires an AAA profile, which provides the policy control attributes for RADIUS servers.
