G.12.1 MO MTSI speech call / WLAN
G.12.1.1 Definition
Test to verify that the UE correctly setup a IMS mobile originated voice call over WLAN and release it. This process is described in 3GPP TS 24.229 [10], clauses 5.1.2A.1, 5.1.3 and 6.1, and TS 26.114 [66], clauses 5.2.1, 6.2.2.1, 6.2.5 and 7.3.1.
G.12.1.2 Conformance requirement
As described in clause 12.12.2 and the following:
[Rel-13, TS 24.229, clause R.2.2.1]
Prior to communication with the IM CN subsystem:
…
a) the UE establishes an IP-CAN bearer for SIP signalling as follows:
…
b) the UE shall acquire a P-CSCF address(es).
…
The methods for P-CSCF discovery are:
…
IV. Obtain P-CSCF address(es) using signalling for access to the EPC via WLAN.
If the UE attaches to the EPC via S2b using untrusted WLAN IP access, the UE shall request P-CSCF IPv4 address(es), P-CSCF IPv6 address(es) or both using the P_CSCF_IP4_ADDRESS attribute, the P_CSCF_IP6_ADDRESS attribute or both in the CFG_REQUEST configuration payload as described in 3GPP TS 24.302 [8U]. The network can provide the UE with the P-CSCF IPv4 address(es), P-CSCF IPv6 address(es) or both using the P_CSCF_IP4_ADDRESS attribute, the P_CSCF_IP6_ADDRESS attribute or both in the CFG_REPLY configuration payload as described in 3GPP TS 24.302 [8U]. If the UE receives multiple P-CSCF IPv4 or IPv6 addresses, the UE shall assume that the list is ordered top-down with the first P-CSCF address within the CFG_REPLY configuration payload as the P-CSCF address having the highest preference and the last P-CSCF address within the CFG_REPLY configuration payload as the P-CSCF address having the lowest preference.
G.12.1.3 Test purpose
As described in clause 12.12.3.
G.12.1.4 Method of test
Initial conditions
UE contains either ISIM and USIM applications or only USIM application on UICC. UE has activated the IP-CAN to the Evolved Packet Core (EPC) via Wireless Local Access Network (WLAN). The UE has registered to IMS according the procedures C.2c.
Expected sequence
NOTE: Only the IMS procedure relevant to the test purpose is described below.
