12.13c.1 Definition

Test to verify that the UE correctly performs IMS mobile terminated speech call setup when using IMS Multimedia Telephony without preconditions after received INVITE request includes the "precondition" option-tag in the Supported header field. This process is described in 3GPP TS 24.229 [10], clauses 5.1.4 and 6.2, TS 24.173 [65] and TS 26.114 [66].

12.13c.2 Conformance requirement

same as 12.13 except

[TS 24.229, Rel-14, clause 5.1.4.1]:

During the session initiation, if local resource reservation is required at the terminating UE and the terminating UE supports the precondition mechanism, and:

…

b) the received INVITE request includes the "precondition" option-tag in the Supported header field, and the precondition mechanism is disabled as specified in subclause 5.1.5A, the terminating UE shall not use the precondition mechanism:

Reference(s)

3GPP TS 24.229 [10] clause 5.1.4.1.

12.13c.3 Test purpose

1) To verify that, when initiating MT MTSI speech call the UE performs correct exchange of SIP protocol signalling messages for setting up the session.

2) To verify that within SIP signalling the UE performs the correct exchange of SDP contents for negotiating media without preconditions after received INVITE request includes the "precondition" option-tag in the Supported header field.

12.13c.4 Method of test

Initial conditions

UE contains either 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 equipp5ed into the UE. SS has performed AKAv1-MD5 authentication with the UE and accepted the registration (IMS security).

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

1-26) UE executes the procedures described in TS 36.508 [94] table 4.5A.7.3-1 steps 1 to26.

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

Steps 1-6 defined in annex C.11

MTSI MT speech call. Referred from 36.508 [94] table 4.5A.7.3-1 for a UE with E-UTRA support.

7

Step 9 defined in annex C.11

The UE responds to INVITE with 180 Ringing

8-9

Step 12-13 defined in annex C.11

SS responds to INVITE with a 200 OK final response and SS acknowledges the receipt of 200 OK for INVITE.

10-11

Step 14-15 defined in annex C.11

The SS sends BYE to release the call and UE sends 200 OK for the BYE request and ends the call.

NOTE: The default messages contents in annex A are used with condition “IMS security” or “GIBA” when applicable
