Bad Handling Of SCCP Protocol Class by SSU (Doc ID 1371919.1)

Last updated on SEPTEMBER 22, 2016

Applies to:

Oracle Communications Service Broker - Version: 3.1.0 and later   [Release: 3.1.0 and later ]
Information in this document applies to any platform.

Symptoms

The SSU does not handle correctly the M3UA routing.
In case AS (Application Server) sends an ApplyCharging and RequestReportBCSM&Continue messages, SSU sends the ApplyCharging message to MSC1, and the RequestReportBCSM&Continue messages to MSC2, so the message order is not guaranteed.
MSC1 and MSC2 handle the global title routing.
The operation mode of the global title routing is load-balanced, but if protocol class is set to1 and signaling link selection (SLS) fields have the same value, the SSU should send the messages to the same destination.
