CAMEL Features

Accept Protocol Feature — Allows the dialog processing to proceed if the application context is acceptable.

Call Barring Feature — A network operator barring feature.

Classify Call Scenario Feature — Classifies the call’s Session Type, Roaming Indicator, and Service Type, which are stored in session state variables for future features.

Call Forwarding Detection Feature — Analyses an MT initialdp to determine if early call forwarding applies for this call.

Closed User Group Feature — Indicates to the OCS any CUGs that apply to the current session, and optionally restricts a subscriber to sessions within a CUG.

Connect And Close Feature — An initial trigger feature which calls connectAndClose() on the feature endpoint.

Continue And Close Feature — An initial trigger feature which calls continueAndClose() on the feature endpoint.

Do Not Monitor Session Feature — An initial trigger feature which instructs Sentinel core not to monitor the call.

Emergency and Special Number Feature — A pre credit check feature early or first in the feature list, to allow the call to continue immediately with no further intervention from Sentinel.

Friends and Family Feature — Sets a special OCS tariff code if a subscriber is making a call to a number in their FnF list.

Home Zone Feature — Determines if the subscriber is within a defined set of home zones on originating calls.

Play Announcement Feature — Plays an announcement to the calling party during call establishment or after the called party disconnects.

Prefix and Suffix Analysis Feature — Sentinel has a set of configurable prefix and suffix lists, scoped by Sentinel selection key, which are used for number analysis.

Relay Dialog During Dialog Analysis Feature — Requests Sentinel core to relay the received dialog to another network element.

Relay Dialog During Initial Trigger Analysis Feature — Requests Sentinel core to relay the received dialog to another network element.

Release Call and Close Dialog Feature — A very simple feature that instructs Sentinel to release the call or SMS and close the dialog with the MSC.

Roaming Default Call Forwarding Feature — Defines roaming-specific forwarding addresses for Busy, No reply cases, to prevent tromboning of forwarded calls to numbers in the subscriber’s HPLMN.

Roaming Re-origination Feature — A way of handling triggers from roaming subscribers on networks that use CAPv1, or networks that use CAPv2 or CAPv3 but are otherwise determined to be unsupported for direct call control from the VPLMN.

Set User Release Cause From Latest Event Report Feature — Inspects the latest EventReportBCSM received by Sentinel and if possible sets the UserReleaseCause integer session state variable to a cause code value appropriate for that event report.

Short Code Feature — A pre-credit check feature early in the feature list (but always after the emergency number feature), to perform number translation on a set of short codes configured for the network.

SMS Normalization Feature — All features executed after this feature access the normalized numbers when accessing the idp in session state.

SS7 Determine Network Operator Feature — Sets the Network Operator element of the Sentinel selection key, based on the value returned by the DetermineNetworkOperator function

SS7 Subscriber Determination Feature — Used to determine the subscriber address, based on parameters from the InitialDP and session state.

SS7 Unconditional Reject Session Feature — Unconditionally refuses the dialog with refuse reason set to USER_NO_REASON_GIVEN.

Validate 3rd Party Call Request Feature (SS7) — Checks the received HTTP request to see if it is well formed.

Validate InitialDP Feature — Performs validation checks to ensure that the InitialDP has sufficient parameters to be handled correctly by Sentinel.

Voice Call Normalization Feature — All features executed after this feature will access the normalized numbers when accessing the idp in session state.
