8.2 Originating Identification Restriction / 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

8.2.1 Test Purpose (TP)

(1)

with { UE being registered to IMS }

ensure that {

when { UE is made to activate OIR }

then { UE authenticates itself using GBA or Digest }

}

(2)

with { UE having started authentication }

ensure that {

when { UE receives 200 OK concluding the authentication }

then { UE sends HTTP request to activate OIR }

}

(3)

with { UE having concluded activation of OIR }

ensure that {

when { UE is made to de-activate OIR }

then { UE sends HTTP request to de-activate OIR }

}

8.2.2 Conformance Requirements

The conformance requirements covered in the present test case are, unless otherwise stated, Rel-15 requirements.

[TS 24.607 clause 4.2.1]:

The OIR service is a service offered to the originating user. It restricts presentation of the originating user’s identity information to the terminating user.

When the OIR service is applicable and activated, the originating network provides the destination network with the indication that the originating user’s identity information is not allowed to be presented to the terminating user. In this case, no originating user’s identity information shall be included in the requests sent to the terminating user. The presentation restriction function shall not influence the forwarding of the originating user’s identity information within the network as part of the simulation service procedures.

[TS 24.607 clause 4.10.1]:

The OIR service can be activated/deactivated using the active attribute of the <originating‑identity‑presentation‑restriction> service element. Activating the OIR service this way activates the temporary mode OIR service. When deactivated and not overruled by operator settings, basic communication procedures apply.

8.2.3 Test description

8.2.3.1 Pre-test conditions

System Simulator:

– SS is configured with shared secret key of IMS AKA algorithm, related to the IMS private user identity (IMPI) configured on the UICC card equipped into the UE.

– SS is listening to SIP default port 5060 for both UDP and TCP protocols.

– At the SS, a HTTP Server is established at port 80 to simulate the XCAP server

– 1 NR Cell

UE:

– The UE contains either ISIM and USIM applications or only USIM application on UICC.

– UE is configured with the name of the XCAP root directory on the XCAP server and the user’s directory name.

– UE has activated an IPCAN bearer with SS.

Preamble:

– The steps 0a and 0b of Annex A.21 have been executed

– During these procedures the UE may request a DNS server address via NAS signalling and as parallel behaviour the UE may resolve the IP address of the XCAP server via DNS.
