8.5 Terminating 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

8.5.1 Test Purpose (TP)

(1)

with { UE being registered to IMS }

ensure that {

when { UE is made to activate TIR }

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 TIR }

}

(3)

with { UE having concluded activation of TIR }

ensure that {

when { UE is made to de-activate TIR }

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

}

8.5.2 Conformance Requirements

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

[TS 24.608 clause 4.2.1]:

The Terminating Identification Restriction (TIR) is a service offered to the terminating party which enables the terminating party to prevent presentation of the terminating identity information to originating party.

[TS 24.608 clause 4.9.1]:

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

8.5.3 Test description

8.5.3.1 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.
