How to Send USSD Responses With More Than 5 Variable Parts with the Play Variable Part Announcement (PAPV) Node (Doc ID 2990765.1)

Goal

In all versions of Oracle Communications Network Charging and Control (OCNCC or NCC) and Oracle Communications Convergent Charging Controller (OC3C or 3C), the Play Variable Part Announcement (PAPV) Feature Node (FN) only allows/supports 5 variable parts (VP).

This is due to the Intelligent Network Application Part (INAP) specification definition for the playAnnouncement (pA) component allowing, at most, 5 VPs.

When using the PAPV node to generate Unstructured Supplementary Service Data (USSD) responses, the PAPV FN is not able to distinguish if it is sending pA components to an external network element to play an announcement or the USSD gateway.

This article will cover a workaround to overcome the 5 VP limit with USSD gateway (USSDGW or ussdgw) to have as many variable parts as necessary.  For example:

The above example requires 8 VPs (represented by "%%"):

• Dollars
• Cents
• Date
• SMS
• Date
• Megabytes
• Kilobytes
• Date

The initial configuration of the USSD notifications/responses are documented in How to Configure a New USSD Notification [Video] (Doc ID 1323100.1) and will not be covered in this article.
