EstablishTemporaryConnection

Usage

This operation is invoked by gsmSCF and it is used to create a connection between a gsmSSF and an assisting SSF as part of a service assist procedure. It is also used to create a connection between a gsmSSF and a gsmSRF when the gsmSRF resides in a separate addressable physical entity.

Expected actions

• When a gsmSSF receives this operation, it should route the call to the assisting gsmSSF/gsmSRF according to the "assistingSSPIPRoutingAddress" parameter.

Invoke parameters

• assistingSSPIPRoutingAddress – indicates the destination address of the gsmSRF/assisting gsmSSF for the assist procedure. It may contain a “correlationID” and “scfID”, but only if these are not specified separately. This parameter should contain routing digits, a “correlationID” and “scfID” when there is no bilateral agreement between PLMNs to transfer the “correlationID” and “scfID” as separate parameters.

• correlationID – parameter used by the gsmSCF to associate the dialogue created by the assisting gsmSSF/gsmSRF to the SCF with the “initialDP” from the gsmSSF. Used only if it's not embedded in the “assistingSSIPRoutingAddress” parameter.

• scfID – the gsmSCF identifier. Enables the assisting gsmSSF to identify to which gsmSCF the “assistRequestInstructions” should be sent to. Used only if it's not embedded in the “assistingSSIPRoutingAddress” parameter.

• extensions

• serviceInteractionIndicatorsTwo – contains an indicator sent from the gsmSCF to the gsmSSF for the control of the connection to the Calling Party.

• na-Info

Result parameters

This operation does not expect a result.
