Table 6-33 Online Charging DRA Network-Wide Options Elements

Fields (* indicates a required field)	Description	Data Input Notes
Session Options
Session State Scope	This sets the scope of messages for which Session State will be stored. Select All Messages to store Session State for all messages. Select None to disable Session State for all messages. Select Specific Messages to store Session State only if the CTF client is configured in the CTFs configuration or OCS is configured with Session State as enabled in OCSs configuration or realm is configured in Realms configuration.	Format: Pulldown menu Range: None, All Messages, Specific Messages Default: None
Session State Unavailable Action	Sets the action to be performed if an in-session Request message cannot be successfully processed due to the inability to retrieve session state associated with the received Session-Id from the Session SBR (for example, session state is not found or an SBR error is encountered). Route to Peer will route the message to a peer using the Peer Routing Table. Send Answer will abandon message processing and send an Answer response containing Answer Result-Code value configured for Session Not Found or SBR Error.	Format: Pulldown menu Range: Send Answer, Route To Peer Default: Send Answer
OCS Selection Options
OCS Pool Selection Mode	This sets the operating mode for selecting the OCS Server for routing the Session Initiation Request messages. When Single Pool mode is selected, the Session Initiation Requests are distributed in a weighted round-robin scheme among all available OCS servers connected to this Node. When Multiple Pools mode is selected, the Session Initiation Requests are routed to an OCS server identified by RBAR in a specific pool of OCS servers.	Format: Pulldown menu Range: Single Pool, Multiple Pools Default: Single Pool

Note:

Keep these consideration in mind when working with network-wide options:

• If Apply is clicked and the Session State Scope transitioned from None to All Messages, a confirmation dialog with a checkbox shall be displayed containing the text: IMPORTANT! The Session State for all the messages will be enabled. The Session State may not be found for already established sessions and the subsequent requests for already established sessions may be rejected. Check the checkbox and click OK to continue, otherwise click Cancel.
• If Apply is clicked and the Session State Scope transitioned from None to Specific Messages, a confirmation dialog with a checkbox shall be displayed containing the text: IMPORTANT! The Session State Scope Specific Messages requires the OCSs, CTFs or Realms to be configured for maintaining Session State. The Session State may not be found for already established sessions and the subsequent requests for already established sessions may be rejected.
• If Apply is clicked and the Session State Scope transitioned from All Messages to Specific Messages, a confirmation dialog with a checkbox shall be displayed containing the text: IMPORTANT! The Session State Scope Specific Messages requires the OCSs, CTFs or Realms to be configured for maintaining Session State. Some or all subsequent in-session messages may be rejected if Destination-Host AVP is not present in them. Check the checkbox and click OK to continue, otherwise click Cancel.
• If Apply is clicked and the Session State Scope transitioned from Specific Messages to All Messages, a confirmation dialog with a checkbox shall be displayed containing the text: IMPORTANT! The Session State for all the messages will be enabled. The Session State may not be found for already established sessions and the subsequent requests for already established sessions may be rejected. Check the checkbox and click OK to continue, otherwise click Cancel.
• If the confirmation dialog for Session State Scope is cancelled by clicking Cancel, control is returned to the Network-Wide Options screen with no data committed.
• If the confirmation dialog for Session State Scope is confirmed by checking the checkbox and clicking OK and no OCS or CTF or Realm is configured for session state maintenance, a Warning Box is displayed on the Network-Wide Options screen containing the text: Session State Scope is configured as Specific Messages but no OCS, CTF or Realm is configured for Session State maintenance. The configured data is saved in the configuration database.
