Enhancement to Connect vs Continue Logic in ACS
(Doc ID 2383623.1)
Last updated on MARCH 07, 2019
Applies to:Oracle Communications Convergent Charging Controller - Version 6.0.0 to 22.214.171.124.0 [Release 6.0 to 12.0.0]
Oracle Communications Network Charging and Control - Version 4.3.0 to 126.96.36.199.0 [Release 4.3 to 12.0.0]
Information in this document applies to any platform.
On all versions of Oracle Communications Network Charging and Control (OCNCC or NCC) and Oracle Communications Convergent Charging Controller (OC3C or 3C) up to and including release 188.8.131.52, the compliance with the Intelligent Network Application Part (INAP) and Customized Applications for Mobile networks Enhanced Logic (CAMEL) Application Part (CAP) specifications around whether a Connect (CON) or a Continue (CUE) operation was returned to a switch in response to an Initial Detection Point (IDP) has always tended to favor a CON over a CUE.
Assuming all the necessary configuration is in place to return a CUE, a CON will still be returned if any of the following conditions were changed between the Called Party Address/Number (CdPA/CdPN or B-Party) in the IDP and the Call Context destination address:
- The complete "digits" in the number (including prefix)
- The Nature of Address (NoA)
- The Screening indicator
- The Presentation indicator
- The Numbering Plan
- The Number Incomplete indicator
Please refer to the Advanced Control Services (ACS) Technical Guide for more information on enabling the CUE operation.
If any of these fields were changed (Normalisation, Control Plan, and/or Denormalisation), a CON will be returned with the DRA set to the new version of the CdPN instead of a CUE (which has no arguments and tells the switch to route/connect the call to the original CdPN it set in the IDP).
It may be desirable to only return a CON if the stored CdPN stored on the switch needs to be replaced with a routing number (for example, short code translation) while a CUE returned if only the NoA and prefix for a number has changed.
Currently this level of logic is not possible with NCC or 3C.
