Cause

The issue is on the SGSN platform side

- s-2005-aa is the PC of the Eagle.
- The SGSN platform is sending SMCG messages to the Eagle with an Affected Point Code (AFTPC) = Eagle's Point code and an Affected SSN = 6.
- Eagle does not have the SSN=6 for itself. This is a SSN number for an HLR platform (Home Location Registration)

=> For which reason the SGSN is sending SCMG messages to the Eagle for an SSN which does not belong to the Eagle ?
=> The issue has to be fixed on the SGSN platform.

Solution

The SGSN configuration must be changed so that it stops sending SCMG messages to the Eagle for an SSN which does not belong to the Eagle.
