E.2 Application usage of SIP
24.3903GPPRelease 17Stage 3TSUnstructured Supplementary Service Data (USSD) using IP Multimedia (IM) Core Network (CN) subsystem IMS
E.2.1 Procedures at the UE
E.2.1.1 3GPP PS data off
E.2.1.1.1 General
The requirements in subclause C.2.1.1.1 apply.
Additionally, the following requirements apply.
In case of SNPN, if the UE supports the 3GPP PS data off:
1) the UE can be configured with:
a) up to two indications of whether the USSI is a 3GPP PS data off exempt service for each subscribed SNPN whose entry exists in the "list of subscriber data", one indication is valid for the UE camping in the subscribed SNPN, and the other indication is valid for any non-subscribed SNPN the UE is camping in using the subscribed SNPN’s credentials; and
b) an indication of whether USSI is a 3GPP PS data off exempt service for PLMN subscription, valid for any non-subscribed SNPN the UE is camping in using the PLMN subscription; and
2) for a subscribed SNPN whose entry exists in the "list of subscriber data", the UE may support being configured with the indication of whether the USSI is a 3GPP PS data off exempt service using one or more of the following methods:
a) the USSI_exempt node of 3GPP TS 24.391 [13], if the UE is in the subscribed SNPN; and
b) the USSI_exempt_non_subscribed_SNPN node of 3GPP TS 24.391 [13], if the UE is in the non-subscribed SNPN.
For PLMN subscription, the UE may support being configured with the indication of whether the USSI is a 3GPP PS data off exempt service using the following method:
1) the USSI_exempt_non_subscribed_SNPN node of 3GPP TS 24.391 [13], if the UE is in the non-subscribed SNPN.
When the UE is only configured with the indication valid for the UE camping in the subscribed SNPN, the UE shall use this indication also when the UE is in the non-subscribed SNPN.
E.2.1.1.2 Enforcement
If the 3GPP PS data off status is "active", and the UE is not configured with indication that USSI is a 3GPP PS data off exempt service:
1) the UE shall terminate according to 3GPP TS 24.229 [6] any SIP dialog established according to subclause 4.5.4 or subclause 4.5.5 with a UE’s contact address containing an IP address associated with a 5GS QoS flow using NG-RAN;
2) the UE shall not invoke the procedures in subclause 4.5.4 with a UE’s contact address containing an IP address associated with a 5GS QoS flow using NG-RAN; and
NOTE 1: If the UE doesn’t invoke the procedures in subclause 4.5.4 due to conditions as described in bullet 2, the UE can attempt a request for an equivalent service via the CS domain – if supported and available – and, otherwise, the UE can attempt the service according to 3GPP TS 24.229 [13] and as described in subclause 4.5.4 via non-3GPP access.
3) if the UE registered a binding with IM CN subsystem, such that:
a) the contact address of the binding contains an IP address associated with a 5GS QoS flow using NG-RAN; and
b) the Contact header field of the binding contains the g.3gpp.nw-init-ussi media feature tag;
then:
a) the UE shall de-register the binding of a UE’s contact address containing an IP address associated with a 5GS QoS flow using NG-RAN from IM CN subsystem according to 3GPP TS 24.229 [6]; or
b) the UE shall re-register the binding of a UE’s contact address containing an IP address associated with a 5GS QoS flow using NG-RAN with IM CN subsystem with a Contact header field not including the g.3gpp.nw-init-ussi media feature tag according to 3GPP TS 24.229 [6].
NOTE 2: Which of the bullets a), and b) the UE performs is influenced by other 3GPP PS data off exempt services.
E.2.2 Procedures at the USSI AS
E.2.2.1 3GPP PS data off
The requirements in subclause C.2.2.1 apply.
Additionally, the following requirements apply.
When serving a UE in an SNPN using an entry of "list of subscriber data", an USSI AS supporting the 3GPP PS data off can be configured with up to two values of whether USSI is a 3GPP PS data off exempt service, one value is valid for the UE camping in the subscribed SNPN, and the other value is valid for the UE camping in the non-subscribed SNPNs with whom service agreements exist.
When the USSI AS is only configured with the indication of whether USSI is a 3GP PS data off exempt service for the UE camping in the subscribed SNPN, the USSI AS shall use this indication also when the UE is in the non-subscribed SNPN.
When serving a UE in an SNPN using PLMN subscription, an USSI AS supporting the 3GPP PS data off can be configured with a value of whether USSI is a 3GPP PS data off exempt service, valid for the UE camping in the non-subscribed SNPNs with whom service agreements exist.
