Structure of Policy Rules

Understanding how a policy rule is structured is helpful in understanding other Policy Management concepts. A policy rule is defined in an if-then structure, consisting of a set of conditions that the MPE device compares to information extracted from protocol messages or obtained from subscriber records, and a set of actions that are executed (or not executed) when the conditions match. Many conditions can be tested for existence or non-existence (by optionally selecting the logical operator NOT or using, where available, the policy condition operator is or is not).
