Incorrect Charging for Data Session Consuming from Unit Balance Type When Service Discount is 100% (Doc ID 1523567.1)

Last updated on SEPTEMBER 12, 2018

Applies to:

Oracle Communications Network Charging and Control - Version 4.4.1 to 4.4.1 [Release 4.4]
Information in this document applies to any platform.

Symptoms

Network Charging and Control (NCC) applies an incorrect charge in the below scenario:

  1.  A data session is triggered to Diameter Control Agent (DCA) by subscriber.
  2.  A discount feature node used in call plan to apply 100% discount for the subscriber.
  3.  The Balance consumed for data session is of type unit.
  4.  The reported data usage is very low.

Sample Event Data Record (EDR):

EDR shows

  1.  Huge cost (COSTS=1.19305e+07)
  2.  Very small reported usage (DURATION=0.10)
  3.  Discount is 100% (DISCOUNTS=1000000)

The huge cost appearing in this EDR is wrong, it is supposed to be zero as 100% discount is applied. The Voucher and Wallet Server (VWS) applies this huge cost on the balance; hence the balance,  of "Unit" type, goes to a large negative value. This prevents the subscriber to start further data sessions.

Changes

System is upgraded to NCC 4.4.1
