    		Test Purpose {

			// In order to transfer of an additional session that can be in originating pre-alerting phase or in an alerting phase, the

			// SCC AS supporting CS to PS dual radio access transfer for calls in an early phase, shall send a SIP REFER request

			// according to 3GPP TS 24.229 [2], IETF RFC 4488 [20] and IETF RFC 3515 [13] as updated by IETF RFC 6665 [81]

			// and IETF RFC 7647 [90] in the dialog created by the SIP INVITE request due to static STI populated as follows:

			//		1) include a Refer-Sub header field with value "false" as specified in IETF RFC 4488 [20];

			//		2) include a Require header field with value "norefersub" as specified in IETF RFC 4488 [20];

			//		3) include a Refer-To header field containing the additional transferred session SCC AS URI for PS to CS dual

			//		radio, where the URI also includes the following URI header fields containing the information related to the

			//		additional transferred session:

			//			a) if an early dialog supporting the additional transferred session exists, the Target-Dialog header field

			//			populated as specified in IETF RFC 4538 [11], containing the dialog identifier of the dialog in the early

			//			phase;

			//			b) if the SCC AS supports the PS to CS dual radio access transfer for originating calls in pre-alerting phase, if

			//			no early dialog supporting the additional transferred session exists, there is a SIP INVITE request from the

			//			served user for which a final SIP response has not been received yet and if an early dialog supporting the

			//			additional transferred session existed and was terminated, the Target-Dialog header field populated as

			//			specified in IETF RFC 4538 [11], containing the dialog identifier on the source access leg of the early dialog

			//			supporting the additional transferred session which existed and was terminated;

			//			c) the Require header field populated with the option tag value "tdialog";

			//			d) if an early dialog supporting the additional transferred session exists, the To header field populated as

			//			specified in IETF RFC 3261 [19], containing the value of the P-Asserted-Identity provided by the remote UE

			//			during the session establishment;

			//			e) the From header field populated as specified in IETF RFC 3261 [19], containing the value of the P-Asserted-

			//			Identity provided by the SC UE during the session establishment;

			//			f) the Content-Type header field with "application/sdp";

			//			g) if an early dialog supporting the additional transferred session exists, the URI header field with hname

			//			"body" populated with SDP describing the media streams as negotiated in the session with the remote UE;

			//			and

			//			h) if the SCC AS supports the PS to CS dual radio access transfer for originating calls in pre-alerting phase, no

			//			early dialog supporting the additional transferred session exists, there is a SIP INVITE request from the

			//			served user for which a final SIP response has not been received yet, the URI header field with the hname

			//			"body" populated with the SDP offer received in the SIP INVITE request from the served user; and

			//		4) application/vnd.3gpp.state-and-event-info+xml MIME with:

			//			a) if a SIP 180 (Ringing) response to the SIP INVITE request has already been received from the remote UE in

			//			any of the early dialogs associated with the originating early session not accepted yet, the state-info XML

			//			element containing "early" and the direction XML element containing "initiator";

			//			b) if a SIP 180 (Ringing) response to the SIP INVITE request has not been received yet from the remote UE in

			//			any of the early dialogs associated with the originating early session not accepted yet and the additional

			//			transferred session was originated by the SC UE, the state-info XML element containing "pre-alerting" and

			//			the direction XML element containing "initiator"; and

			//			c) if a SIP 180 (Ringing) response to the INVITE request has already been received on the source access leg,

			//			the state-info XML element containing "early" and the direction XML element containing "receiver"
