12.12a.1 Definition

Test to verify that the UE correctly performs IMS mobile originated voice call setup and release when using IMS Multimedia Telephony without preconditions. This process is described in 3GPP TS 24.229 [10], clauses 5.1.3 and 6.1, TS 24.173 [65] and TS 26.114 [66].

12.12a.2 Conformance requirement

As described in 12.12.2 except

[TS 24.229, Rel-14 onwards, clause 5.1.3.1]:

The "integration of resource management and SIP" extension is hereafter in this subclause referred to as "the precondition mechanism" and is defined in RFC 3312 [30] as updated by RFC 4032 [64].

The preconditions mechanism should be supported by the originating UE.

If the precondition mechanism is disabled as specified in subclause 5.1.5A, the UE shall not use the precondition mechanism.

[TS 24.229, clause 5.1.5A]:

The precondition disabling policy indicates whether the UE is allowed to use the precondition mechanism or whether the UE is not allowed to use the precondition mechanism.

If the precondition disabling policy is not configured, the precondition disabling policy is assumed to indicate that the UE is allowed to use the precondition mechanism.

The UE may support the precondition disabling policy.

If the UE supports the precondition disabling policy, the UE may support being configured with the precondition disabling policy using one or more of the following methods:

a) the Precondition_disabling_policy node of the EF_IMSConfigData file described in 3GPP TS 31.102 [15C];

b) the Precondition_disabling_policy node of the EF_{IMSConfigData} file described in 3GPP TS 31.103 [15B]; and

c) the Precondition_disabling_policy node of 3GPP TS 24.167 [8G].

If the UE is configured with both the Precondition_disabling_policy node of 3GPP TS 24.167 [8G] and the Precondition_disabling_policy node of the EF_{IMSConfigData} file described in 3GPP TS 31.102 [15C] or 3GPP TS 31.103 [15B], then the Precondition_disabling_policy node of the EF_{IMSConfigData} file shall take precedence.

NOTE: Precedence for files configured on both the USIM and ISIM is defined in 3GPP TS 31.103 [15B].

The precondition mechanism is disabled, if the UE supports the precondition disabling policy and the precondition disabling policy indicates that the UE is not allowed to use the precondition mechanism.

The precondition mechanism is enabled, if:

1) the UE does not support the precondition disabling policy; or

2) the UE supports the precondition disabling policy and the precondition disabling policy indicates that the UE is allowed to use the precondition mechanism.

[TS 24.229, clause 6.1.2]:

An INVITE request generated by a UE shall contain a SDP offer and at least one media description. This SDP offer shall reflect the calling user’s terminal capabilities and user preferences for the session.

…

NOTE 2: If the originating UE does not use the precondition mechanism (see subclause 5.1.3.1), it will not include any precondition information in the SDP message body.

12.12a.3 Test purpose

1) To verify that when initiating MO call the UE performs correct exchange of SIP protocol signalling messages for setting up the session; and

2) To verify that UE performs the correct exchange of SDP messages for negotiating media without using preconditions.

3) To verify that the UE is able to release the call.

12.12a.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). UE is configured to not use the precondition mechanism.

Test procedure applicable for a UE with E-UTRA support (TS 34.229-2 [5] A.18/1)

1-14) UE executes the procedures described in TS 36.508 [94] table 4.5A.6.3-1 steps 1 to 14.

Expected sequence

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

Step	Direction		Message	Comment
	UE	SS
1-9			Steps 1-9 defined in annex C.21f	MTSI MO speech call. Referred from 36.508 [94] table 4.5A.6.3-1 for a UE with E-UTRA support.
10	🡪		BYE	The UE releases the call with BYE
11	🡨		200 OK	The SS sends 200 OK for BYE
