12.29.1 Definition

Test to verify that the MO UE correctly cancels video call establishment. This process is described in 3GPP TS 24.229 [10], clauses 5.1.3.

12.29.2 Conformance requirement

[TS 24.229, clause 5.1.3.1]:

12.29.3 Test purpose

1) To verify that MO UE correctly cancels video call establishment.

12.29.4 Method of test

Initial conditions

UE contains either SIM application (GIBA), ISIM and USIM applications or only USIM application on UICC. UE has discovered P-CSCF and registered to IMS services, by executing the generic test procedure in Annex C.2 or C.2a (GIBA only) up to the last step.

SS is configured with the shared secret key of IMS AKA algorithm, related to the IMS private user identity (IMPI) configured on the UICC card equipped into the UE. SS has performed AKAv1-MD5 authentication with the UE and accepted the registration (IMS security).

Expected sequence

NOTE: Only the IMS procedure relevant to the test purpose is described below.

Step	Direction		Message	Comment
	UE	SS
1-11			Steps 1-11 defined in annex C.25
11A				The MO UE cancels a video call establishment manually.
12	🡪		CANCEL
13	🡨		200 OK	SS responds CANCEL with 200 OK.
14	🡨		487 Request Terminated	SS responds INVITE with 487 Request Terminated
15	🡪		ACK	UE acknowledges.
