Question: What is the primary difference between the 'Installation' operation for dynamic PCC rules and the 'Activation' operation for predefined PCC rules in a Policy and Charging Control (PCC) context?
Option 1: Installation adds a new rule, while Activation modifies an existing rule's parameters.
Option 2: Installation is for permanent rules, whereas Activation is for temporary rules.
Option 3: Installation affects all users, but Activation is user-specific.
Option 4: Installation provisions a new, non-existent PCC rule, while Activation enables a predefined (already provisioned) PCC rule.
Explanation: The correct answer highlights the key distinction between managing dynamic vs. predefined PCC rules. 'Installation' is about provisioning a dynamic PCC rule that didn't exist before, whereas 'Activation' is about enabling a predefined PCC rule that is already provisioned but may be currently inactive. This difference is crucial for effective Policy and Charging Control in telecom networks, as it impacts how resources are allocated and services are billed.
