Section: 6.3.10 Handling of 3GPP PS data off
Content: A UE, which supports 3GPP PS data off (see 3GPP TS 23.401[ General Packet Radio Service (GPRS) enhancements for Evolved Universal Terrestrial Radio Access Network (E-UTRAN) access ]  [10]), 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) ]  [15A] or in the EF3GPPPSDATAOFF USIM file as specified in 3GPP TS 31.102[ Characteristics of the Universal Subscriber Identity Module (USIM) application ]  [17]: - a list of 3GPP PS data off exempt services to be used in the HPLMN or EHPLMN (if the EHPLMN list is present); and - 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 (if the EHPLMN list is present) is configured at the UE, this list shall be also used in the VPLMN. If the UE supports 3GPP PS data off, the UE shall provide the 3GPP PS data off UE status in the Protocol configuration options IE during attach, UE-requested PDN connectivity, and UE-requested bearer resource modification procedure (see clause 5.5.1, 6.5.1, and 6.5.4). NOTE 1: The sending of the 3GPP PS data off UE status to the network happens also when the user activates or deactivates 3GPP PS data off while connected via WLAN access only, and then handover to 3GPP access occur. The network informs the UE about the support of 3GPP PS data off during the activation of the default bearer of a PDN connection (see clause 6.4.1). If 3GPP PS data off support is not indicated in the Protocol configuration options IE in the ACTIVATE DEFAULT EPS BEARER CONTEXT REQUEST message, the UE shall not indicate any change of 3GPP PS data off UE status for the PDN connection established by the default EPS bearer context activation procedure; otherwise the UE shall indicate change of the 3GPP PS data off UE status for the PDN connection by using the UE-requested bearer resource modification procedure as specified in clause 6.5.4. If the network does not provide indication of support of 3GPP PS data off during default EPS bearer context activation procedure of the PDN connection, the UE behaviour for non-exempt service requests from the network is implementation dependent. When the 3GPP PS data off UE status is "activated": a) the UE does not send uplink IP packets except: - for those services indicated in the list of 3GPP PS data off exempt services to be used in the HPLMN or EHPLMN (if the EHPLMN list is present) as specified in 3GPP TS 24.368[ Non-Access Stratum (NAS) configuration Management Object (MO) ]  [15A] when the UE is in its HPLMN or EHPLMN (if the EHPLMN list is present); - for those services indicated in the list of 3GPP PS data off exempt services to be used in the HPLMN or EHPLMN (if the EHPLMN list is present) 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 (if the EHPLMN list is present) is configured to the UE as specified in 3GPP TS 24.368[ Non-Access Stratum (NAS) configuration Management Object (MO) ]  [15A]; - 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) ]  [15A]; - 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 ]  [17]; - 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 ]  [13D]; and - 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 ]  [50]; and b) the UE does not send uplink non-IP or Ethernet user data packets. Otherwise the UE sends uplink user data packets without restriction. NOTE 2: 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 ]  [13D] in L.3.1.5.
