ECS Features in Release 8.1
This section provides information for new features in the Enhanced Charging Service in 
Release 8.0.
Enhanced Charging Service in Optimized Mode

MPORTANT
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).
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.
The Optimized mode benefits the in-line services that run as part of ECS, i.e. Firewall and 
Peer-to-Peer with performance improvement.

By default, on installing Release 8.1, the system comes up with ECS in non-optimized 
mode. If the ECS mode is changed from the default (non-optimized) mode to the Optimized 
mode, or vice-versa, the system must be rebooted for the change to take effect.

In UMTS networks, if ECS is configured in the Optimized mode, secondary PDP context 
traffic does not undergo ECS processing.
