COA Script Service Overview

The service activation engine (SAE) can use change-of-authorization (COA) messages to manage services for a specific subscriber session. The COA script service allows the SAE to exchange COA messages with third-party devices that do not support Common Open Policy Service (COPS) protocol to activate or deactivate services for specific subscriber sessions. When the SAE activates a COA script service session, the session sends COA messages to a RADIUS-enabled device. This method uses RADIUS attributes and RADIUS vendor-specific attributes (VSAs) to identify a subscriber session whose services are to be activated or deactivated.
