I.8.1 Initial registration / Converged IP Communications

I.8.1a Single IMS Registration via E-UTRA / Converged IP Communications

I.8.1a.1 Definition

Test to verify that the UE can correctly register to IMS for Converged IP Communications [144] via E-UTRA when equipped with UICC that contains either both ISIM and USIM applications or only USIM application but not ISIM. The process consists of sending initial registration to S-CSCF via the P-CSCF discovered, authenticating the user and finally subscribing to the registration event package for the registered default public user identity, using E-UTRA access. The single registration shall register multi-media telephony, SMSoIP and advanced messaging services via a single IMS core network.

I.8.1a.2 Conformance requirement

As described in clause 8.1.2. In addition,

a) to verify that the UE performs a single IMS registration for multi-media telephony, SMSoIP and advanced messaging services using the IMS APN over E-UTRA access.

I.8.1a.3 Test purpose

As described in clause 8.1.3. In addition:

a) to verify that the UE performs a single IMS registration for multi-media telephony, SMSoIP and advanced messaging services using the IMS APN over E-UTRAN access.

I.8.1a.4 Method of test

Initial conditions

UE contains either ISIM and USIM applications or only USIM application on UICC. UE is not registered to IMS services.

SS is configured with the IMSI within the USIM application, the home domain name, public and private user identities together with the shared secret key of IMS AKA algorithm, related to the IMS private user identity (IMPI) that is configured on the UICC card equipped into the UE. SS is listening to SIP default port 5060 for both UDP and TCP protocols. SS is able to perform AKAv1-MD5 authentication algorithm for that IMPI, according to 3GPP TS 33.203 [14] clause 6.1 and RFC 3310 [17].

UE is capable of Converged IP Communications [144], and the UE determined that one APN is to be used for SIP signalling as configuration parameter “RCS VOLTE SINGLE REGISTRATION is set to 1, configuration parameter “NO MSRP SUPPORT” is set to empty value, and UE is not roaming outside its HPMN.

Test procedure

UE executes the procedures described in TS 36.508 [94] subclause 4.5.2.3.

SS checks that the UE does not send a second REGISTER request after completing procedure C.2.

Expected sequence

Step	Direction		Message	Comment
	UE	SS
1-11			Steps 1-11 defined in Annex C.2
12				The SS waits 10 seconds in order to check that the UE does not send another REGISTER request.

I.8.1a.5 Test requirements

The UE shall send requests and responses as described in clause I.8.1a.4.

I.8.1b Dual IMS Registration via E-UTRA / Converged IP Communications

I.8.1b.1 Definition

Test to verify that the UE can correctly register to IMS for Converged IP Communications [144] via E-UTRA when equipped with UICC that contains either both ISIM and USIM applications or only USIM application but not ISIM. The process consists of sending two IMS registrations, each to the respective S-CSCF via the respective P-CSCF discovered, authenticating the user and finally subscribing to the registration event package for the registered default public user identity, using E-UTRA access (authentication and subscription happens once per registration). One IMS registration shall register multi-media telephony and SMSoIP, and the second registration shall register advanced messaging services.

I.8.1b.2 Conformance requirement

For the registration for multi-media telephony and SMSoIP, as described in clause I.8.1a.2.

I.8.1b.3 Test purpose

As described in clause 8.1.3. In addition:

a) to verify that the UE performs two IMS registrations, one for multi-media telephony and SMSoIP using the IMS APN, and another one for advanced messaging services using the HOS APN, both over E-UTRAN access.

I.8.1b.4 Method of test

Initial conditions

UE contains either ISIM and USIM applications or only USIM application on UICC. UE is not registered to IMS services.

UE is capable of Converged IP Communications [144], and the UE determined that two APN’s are to be used for SIP signalling as configuration parameter “RCS VOLTE SINGLE REGISTRATION is set to 0, configuration parameter “NO MSRP SUPPORT” is set to empty value, and UE is not roaming outside its HPMN.

Test procedure

UE executes the procedures described in TS 36.508 [94] table 4.5A.28.3-1.

I.8.1b.5 Test requirements

The UE shall send requests and responses as described in clause I.8.1b.4.

I.8.1c Single IMS Registration via WLAN / Converged IP Communications

I.8.1c.1 Definition

Test to verify that the UE can correctly register to IMS for Converged IP Communications [144] via EPC-integrated WLAN when equipped with UICC that contains either both ISIM and USIM applications or only USIM application but not ISIM. The process consists of sending initial registration to S-CSCF via the P-CSCF discovered, authenticating the user and finally subscribing to the registration event package for the registered default public user identity, using WLAN access. The single registration shall register multi-media telephony, SMSoIP and advanced messaging services via a single IMS core network.

I.8.1c.2 Conformance requirement

As clause I.8.1a.2.

I.8.1c.3 Test purpose

As described in clause G.8.1.3. In addition,

a) to verify that the UE performs a single IMS registration for multi-media telephony, SMSoIP and advanced messaging services using the IMS APN over integrated WLAN access.

I.8.1c.4 Method of test

Initial conditions

UE contains either ISIM and USIM applications or only USIM application on UICC. UE is not registered to IMS services.

Test procedure

As described in C.2c using WLAN access.

SS checks that the UE does not send a second REGISTER request after completing above procedure.

Expected sequence

Step	Direction		Message	Comment
	UE	SS
1-9				Steps 1-9 of Annex C.2c
10				The SS waits 10 seconds in order to check that the UE does not send another REGISTER request.

I.8.1c.5 Test requirements

The UE shall send requests and responses as described in clause I.8.1c.4.
