USSD GW Truncating USSD String at 130 Bytes (Doc ID 2420220.1)

Last updated on OCTOBER 02, 2019

Applies to:

Oracle Communications Convergent Charging Controller - Version 6.0.0 and later
Oracle Communications Network Charging and Control - Version 4.3.0 and later
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), when attempting to send a Unstructured Supplementary Service Data (USSD) notification to a handset, USSD strings exceeding 130 characters in length are truncated.

There are no alarms or messages in any logs to suggest an error and when debug is enabled, there are still no messages to suggest the string was truncated.  Only a network trace shows the truncated message leaving the Service Logic Controller (SLC).

For example, when trying to send the following text:

'Get xxxxx credit on xxx xxxxx xxxx xxxxxl xxxxxxxxx with validity up to xx days, and xx% bonus xxxxxx Credit recharges. Dial xxxx# xxxxxxxxx xxxxxx'

The following is seen in the network trace:

As a result, subscribers see truncated notifications on their handsets leading to bad user experience.
