Hi Ladies and Gents.,

For EstablishTemporaryConnection (ETC) the following CAMEL functions are used:-

-gsmSCF,
-gsmSSF, and
-gsmsRF/IP, or using announcement resources with the assisting gsmSSF

The above can be from different Telecommunication vendors.

Using your nodes you should be able to obtain a trace and focus on the following parameters:-

– assistingSSPIPRoutingAddress

This parameter indicates the destination address of the gsmSRF or assisting gsmSSF for assist procedure. The “assistingSSPIPRoutingAddress” may contain embedded within it, a “correlationID” and “scfID”, but only if “correlationID” and “scfID” are not specified separately.

– correlationID:

This parameter is used by the gsmSCF to associate the dialogue created from the assisting SSF (or the gsmSRF)
to the gsmSCF with the InitialDP from the gsmSSF. The “correlationID” is used only if the correlation ID is not
embedded in the “assistingSSPIPRoutingAddress”. The network operators have to decide about the actual
mapping of this parameter on the signalling system.

– scfID:

This parameter indicates the gsmSCF identifier and enables the assisting SSF to identify which gsmSCF the
AssistRequestInstructions should be sent to. The “scfID” is used only if the SCF ID is not embedded in the
“assistingSSPIPRoutingAddress”. The network operators have to decide about the actual mapping of this
parameter on the signalling system.

– serviceInteractionIndicatorsTwo:

This parameter contains an indicator sent from the gsmSCF to the gsmSSF for control of the through connection.
