The scope and description of the present TC is the same as test case 13.1.19 with the following differences:

– EPS network feature support in Table 13.1.19.3.3-1: EPS network feature support IE value ‘0000 0010’B that indicates “IMS voice over PS session in S1 mode not supported, emergency bearer services in S1 mode supported” replaces ‘0000 0001’B.

– In Table 13.1.19.3.2-1, following differences are applicable:

– IF (px_RATComb_Tested = EUTRA_UTRA), UE may attempt the generic procedures for IMS signalling defined in TS 36.508[18] clause 4.5A.3A (for cell 5) after step 5a19.

– IF (px_RATComb_Tested = EUTRA_GERAN), UE may attempt the generic procedures for IMS signalling defined in TS 36.508[18] clause 4.5A.3B (for cell 24) after step 5b30.
