Section: 6.2.10 Handling of 3GPP PS data off
Content: In case of PLMN, a UE, which supports 3GPP PS data off (see 3GPP TS 23.501[ System architecture for the 5G System (5GS) ]  [8]), can be configured with up to two lists of 3GPP PS data off exempt services as specified in 3GPP TS 24.368[ Non-Access Stratum (NAS) configuration Management Object (MO) ]  [17] or in the EF3GPPPSDATAOFF USIM file as specified in 3GPP TS 31.102[ Characteristics of the Universal Subscriber Identity Module (USIM) application ]  [22]: a) a list of 3GPP PS data off exempt services to be used in the HPLMN or EHPLMN; and b) a list of 3GPP PS data off exempt services to be used in the VPLMN. If only the list of 3GPP PS data off exempt services to be used in the HPLMN or EHPLMN is configured at the UE, this list shall be also used in the VPLMN. In case of SNPN, a UE, which supports 3GPP PS data off (see 3GPP TS 23.501[ System architecture for the 5G System (5GS) ]  [8]), can be configured with: a) up to two lists of 3GPP PS data off exempt services as specified in 3GPP TS 24.368[ Non-Access Stratum (NAS) configuration Management Object (MO) ]  [17] for each subscribed SNPN whose entry exists in the "list of subscriber data": 1) a list of 3GPP PS data off exempt services to be used in the subscribed SNPN; and 2) a list of 3GPP PS data off exempt services to be used in the non-subscribed SNPN; and b) one list of 3GPP PS data off exempt services as specified in 3GPP TS 24.368[ Non-Access Stratum (NAS) configuration Management Object (MO) ]  [17] for PLMN subscription: 1) a list of 3GPP PS data off exempt services to be used in the non-subscribed SNPN. If only the list of 3GPP PS data off exempt services to be used in the subscribed SNPN is configured for the selected entry of "list of subscriber data", this list shall be also used in the non-subscribed SNPN. If the UE supports 3GPP PS data off, the UE shall provide the 3GPP PS data off UE status in the Extended protocol configuration options IE during UE-requested PDU session establishment procedure except for the transfer of a PDU session from non-3GPP access to 3GPP access and except for the establishment of user plane resources on the other access for the MA PDU session(see subclause 6.4.1), and during UE-requested PDU session modification procedure (see subclause 6.4.2), regardless of associated access type of the PDU session. If the UE requests a PDU session establishment procedure in order to transfer a PDU session from non-3GPP access to 3GPP access, or in order to establish user plane resources on the other access for the MA PDU session over 3GPP access or non-3GPP access, and: a) if the 3GPP PS data off UE status has changed since the last providing to the network, the UE shall provide the 3GPP PS data off UE status in the Extended protocol configuration options IE; or b) if the 3GPP PS data off UE status has not changed since the last providing to the network, the UE need not provide the 3GPP PS data off UE status. The network shall support of 3GPP PS data off. The UE shall indicate change of the 3GPP PS data off UE status for the PDU session by using the UE-requested PDU session modification procedure as specified in subclause 6.4.2. When the 3GPP PS data off UE status is "activated": a) the UE does not send uplink IP packets via 3GPP access except: 1) for those services indicated in the list of 3GPP PS data off exempt services to be used in the HPLMN or EHPLMN as specified in 3GPP TS 24.368[ Non-Access Stratum (NAS) configuration Management Object (MO) ]  [17] when the UE is in its HPLMN or EHPLMN; 2) for those services indicated in the list of 3GPP PS data off exempt services to be used in the subscribed SNPN, configured for the selected entry of "list of subscriber data", as specified in 3GPP TS 24.368[ Non-Access Stratum (NAS) configuration Management Object (MO) ]  [17] when the UE is in the subscribed SNPN; 3) for those services indicated in the list of 3GPP PS data off exempt services to be used in the HPLMN or EHPLMN when the UE is in the VPLMN, if only the list of 3GPP PS data off exempt services to be used in the HPLMN or EHPLMN is configured to the UE as specified in 3GPP TS 24.368[ Non-Access Stratum (NAS) configuration Management Object (MO) ]  [17]; 4) for those services indicated in the list of 3GPP PS data off exempt services to be used in the subscribed SNPN, configured for the selected entry of "list of subscriber data", when the UE is in a non-subscribed SNPN and only the list of 3GPP PS data off exempt services to be used in the subscribed SNPN is configured for the selected entry of "list of subscriber data" as specified in 3GPP TS 24.368[ Non-Access Stratum (NAS) configuration Management Object (MO) ]  [17]; 5) for those services indicated in the list of 3GPP PS data off exempt services to be used in the VPLMN when the UE is in the VPLMN, if the list of 3GPP PS data off exempt services to be used in the VPLMN is configured to the UE as specified in 3GPP TS 24.368[ Non-Access Stratum (NAS) configuration Management Object (MO) ]  [17]; 6) for those services indicated in the list of 3GPP PS data off exempt services to be used in the non-subscribed SNPN, configured for the selected entry of "list of subscriber data", when the UE is in a non-subscribed SNPN and the list of 3GPP PS data off exempt services to be used in the non-subscribed SNPN is configured for the selected entry of "list of subscriber data" as specified in 3GPP TS 24.368[ Non-Access Stratum (NAS) configuration Management Object (MO) ]  [17]; 7) for those services indicated in the list of 3GPP PS data off exempt services to be used in the non-subscribed SNPN, configured for the selected PLMN subscription, when the UE is in the non-subscribed SNPN and the list of 3GPP PS data off exempt services to be used in the non-subscribed SNPN is configured for the selected PLMN subscription as specified in 3GPP TS 24.368[ Non-Access Stratum (NAS) configuration Management Object (MO) ]  [17]; 8) for those services indicated in the EF3GPPPSDATAOFF USIM file as specified in 3GPP TS 31.102[ Characteristics of the Universal Subscriber Identity Module (USIM) application ]  [22]; 9) any uplink traffic due to procedures specified in 3GPP TS 24.229[ IP multimedia call control protocol based on Session Initiation Protocol (SIP) and Session Description Protocol (SDP); Stage 3 ]  [14]; and 10) any uplink traffic due to procedures specified in 3GPP TS 24.623[ Extensible Markup Language (XML) Configuration Access Protocol (XCAP) over the Ut interface for Manipulating Supplementary Services ]  [20]; b) the UE does not send uplink Ethernet user data packets via 3GPP access; and c) the UE does not send uplink Unstructured user data packets via 3GPP access. Otherwise the UE sends uplink user data packets without restriction. NOTE: If the UE supports 3GPP PS data off, uplink IP packets are filtered as specified in 3GPP TS 24.229[ IP multimedia call control protocol based on Session Initiation Protocol (SIP) and Session Description Protocol (SDP); Stage 3 ]  [14] in U.3.1.5. 3GPP PS data off does not restrict sending of uplink user data packets via non-3GPP access of a single access PDU session or an MA PDU session.
