8.19 Barring of All Incoming Calls from anonymous users / 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
8.19.1 Test Purpose (TP)
(1)
with { UE being registered to IMS }
ensure that {
when { UE is made to activate ACR }
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 ACR }
}
(3)
with { UE having concluded activation of ACR }
ensure that {
when { UE is made to de-activate ACR }
then { UE sends HTTP request to de-activate ACR }
}
8.19.2 Conformance Requirements
The conformance requirements covered in the present test case are, unless otherwise stated, Rel-15 requirements.
[TS 24.611, clause 4.2.1]:
The Anonymous Communication Rejection (ACR) service allows the served user to reject incoming communications on which the asserted public user identity of the originating user is restricted. In case the asserted public user identity of the originating user is not provided then the communication shall be allowed by the ACR service.
An example where the originating user restricts presentation of the asserted public user identity is when he activated the OIR service 3GPP TS 24.607.
The originating user is given an appropriate indication that the communication has been rejected due to the application of the ACR service.
The Anonymous Communication Rejection (ACR) simulation service is a special case of the ICB service, which is highlighted here because it is a regulatory service in many countries. The ACR service can be activated for a specific subscriber by configuring an ICB service barring rule where the conditional part contains the "Condition=anonymous" and the action part "allow=false".
[TS 24.611, clause 4.5.2.6.2]:
The AS providing the ACR service shall reject all incoming communications where the incoming SIP request:
1) includes the P-Asserted-Identity header field AND includes the Privacy header field indicating "id" as specified in RFC 3325; or
2) includes the P-Asserted-Identity header field AND includes the Privacy header field indicating "header" as specified in RFC 3323; or
3) includes the P-Asserted-Identity header field AND includes the Privacy header field indicating "user" as specified in RFC 3323; or
4) includes the P-Asserted-Identity header field AND includes the Privacy header field indicating "critical" as specified in RFC 3323.
[TS 24.611, clause 4.9.1.4]:
anonymous: To comply with the requirements as set for simulation of the ACR service, the anonymous element shall only evaluate to true when the conditions as set out in clause 4.5.2.6.2 for asserted originating public user identity apply.
8.19.3 Test description
8.19.3.1 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.
