7.4a MTSI MO Voice Call with preconditions at both originating UE and terminating UE / Default Configuration / 5GS

34.229-53GPPInternet Protocol (IP) multimedia call control protocol based on Session Initiation Protocol (SIP) and Session Description Protocol (SDP)Part 5: Protocol conformance specification using 5G System (5GS)Release 16TSUser Equipment (UE) conformance specification

7.4a.1 Test Purpose (TP)

(1)

with { UE being registered to IMS and configured to use preconditions and configured to use the EVS default configuration included first in the initial SDP offer }

ensure that {

when { UE is being made to initiate a voice call }

then { UE sends INVITE for voice call with preconditions and EVS default configuration }

}

(2)

with { UE having sent INVITE with preconditions }

ensure that {

when { UE receives 100 Trying followed by 183 Session Progress }

then { UE sends PRACK for 183 Session Progress }

}

(3)

with { UE having sent PRACK }

ensure that {

when { UE receives 200 OK for PRACK and resources are available }

then { UE sends UPDATE }

}

(4)

with { UE having sent UPDATE }

ensure that {

when { UE receives 200 OK for UPDATE followed by 180 Ringing sent reliably }

then { UE sends PRACK for 180 Ringing }

}

(5)

with { UE having sent PRACK for 180 Ringing }

ensure that {

when { UE receives 200 OK for PRACK followed by 200 OK for INVITE }

then { UE sends ACK }

}

7.4a.2 Conformance Requirements

Same as test case 7.4.

7.4a.2A Profile requirements (Informative)

Same as test case 7.4 with the following additions:

[NG.114 Version 1.0 and 2.0, clause 3.2.2.3]:

The configuration of the EVS payload type to be included first in the initial SDP offer for EVS is defined by the EVS/Br and EVS/Bw parameters as specified in Annex C.3, which must be configured to one of the five above EVS Configurations.

[NG.114 Version 1.0 and 2.0, clause C.3]:

Table C.3-1 contains the configuration parameters with their default values, that must be supported by the UE and the network. The UE must use the default value for each parameter in Table C.3-1 unless configured differently as described in Annex C.2.
