8.7 Communication Forwarding Unconditional / 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

8.7.1 Test Purpose (TP)

(1)

with { UE being registered to IMS }

ensure that {

when { UE is made to activate CFU }

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 CFU }

}

(3)

with { UE having concluded activation of CFU }

ensure that {

when { UE is made to de-activate CFU }

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

}

8.7.2 Conformance Requirements

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

[TS 24.604, clause 4.2.1.2]:

The CFU service enables a served user to have the network redirect to another user communications which are addressed to the served user’s address. The CFU service may operate on all communication, or just those associated with specified services. The served user’s ability to originate communications is unaffected by the CFU supplementary service. After the CFU service has been activated, communications are forwarded independent of the status of the served user.

As a service provider option, a subscription option can be provided to enable the served user to receive an indication that the CFU service has been activated. This indication shall be provided when the served user originates a communication if the CFU service has been activated for the served user’s address and for the service requested for the communication.

The maximum number of diversions permitted for each communication is a service provider option. The service provider shall define the upper limit of diversions. When counting the number of diversions, all types of diversion are included.

8.7.3 Test description

8.7.3.1 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:

– 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.
