Enhanced Charging Service in Optimized Mode

In Release 8.1, Enhanced Charging Service must be enabled in Optimized mode.
In the Optimized mode, ACS Managers (ACSMgrs) are merged with Session Manager
(SessMgr), and enhanced charging facilities run as part of the SessMgr. Also, the controller
functionality is unified, i.e. the ACS Controller (ACSCtrl) is merged with the Session
Controller (SessCtrl).

functionality is unified, i.e. the ACS Controller (ACSCtrl) is merged with the Session
Controller (SessCtrl).
In the Optimized mode, recovery/reconciliation of ACSCtrl with ACSMgrs is coupled with
SessCtrl recovery. I.e., SessCtrl handles recovery of enhanced charging specific
configuration. And, reconciliation of ACSCtrl vis-à-vis SRDB tasks is added to SessCtrl
reconciliation. SRDB tasks hold the third-party database, which is used for static
category-based content-filtering. In Release 8.0, these SRDB tasks are handled by ACSCtrl.
In Release 8.1 the SessCtrl controls these SRDB tasks.
