TON/NOA of VLR Number Not Interpreted Correctly in Normalisation Rule (Doc ID 1990271.1)

Last updated on JULY 27, 2017

Applies to:

Oracle Communications Network Charging and Control - Version 4.3.0 to 5.0.2 [Release 4.3 to 5.0]
Information in this document applies to any platform.

Symptoms

In all versions of Oracle Communications Network Charging and Control versions up to and including 5.0.2, Advanced Calling Services (ACS) does not correctly interpret the Nature of Address (NoA) when the normalization is defined for the Visitor Location Register (VLR) number, defined by the 7th parameter of the rule set to "v" or "V":

(42,-,0,A,1,32,v)

This rule, defined for VLR numbers which NoA value "1" means international will not be matched.

It is expected that ACS correctly matches the NoA for VLR numbers.

NOTE: Note the 'v' value for "prefix source" in NormalisationRule (7th parameter).
         If you reconfigure the normalisation rule as: NormalisationRule (42,-,0,A,1,32,m) - 'm' instead of 'v' - so that the Mobile Switching Center (MSC) address is matched, then it does work, even though the MSC address also has a NoA (TON) value of 1.

Below a sample from slee_acs.log files with DEBUG activated:

MSC → using 'm' value in NormalisationRule (42,-,0,A,1,32,m)
