Summary
This operation will allow enabling/disabling individual policies running in PDP engine.
The policy still remains in PDP engine, only the execution of ONSET events/decision calls are stopped temporarily.
It is mainly beneficial in scenarios where network operators/administrators want to disable a particular policy in PDP engine for a period of time due to a failure in the system or for scheduled maintenance.

Currently available alternative solutions
| Solution | Rank | Comments |
|---|---|---|
| ACTIVE/PASSIVE state change at PdpGroup Level | LOW | This solution makes all the policies running in PDP engine to stop/start execution. But the intent is to stop/start individual policies. |
| Deploy/Undeploy policy in PDP Engine | MEDIUM | This solution might work but includes overhead of deploying/undeploying policies from PAP to PDP engine. Delta update might help improve the list sent by PAP. Also, needs to know what happens if an event is under process and PDP receives message to undeploy policy. |
