Test objective "Verify that the SCC AS terminates the call over CS after receiving a SIP 488"
Reference
"ETSI TS 124 237 [1], Clauses 9.3.5.5 and 10.4.7 in 3GPP TS 24.292 [4]"
Config Id CFG_SCCAS_01
PICS Selection NONE // TODO
Initial conditions with {
the UE entity isRegisteredTo the IMS
// TODO:
// SIP INVITE was sent with:
// creating the session in the terminating alerting phase without an SDP MIME body
// SCC AS supports PS to CS dual radio access
}
Expected behaviour
ensure that {

the IUT entity receives an r_488_NotAcceptableHere containing

CallId indicating value PX_UE_A_CALLID,
Via indicating value PX_UE_A_VIA,
Route indicating value PX_UE_A_SERVICE_ROUTE;

the IUT entity sends an REFER containing

Via indicating value PX_UE_A_VIA,
Route indicating value PX_UE_A_SERVICE_ROUTE,

ContentType indicating value "application/sdp", // E. the Content-Type header field with "application/sdp";
