[{"name":"S2-1910850","title":"LS from CT WG3: LS on policy control for ATSSS","source":"CT WG3","contact":"Xiaoyun Zhou","contact-id":38525,"tdoctype":"LS in","for":"Action","abstract":"CT WG3 is working on the ATSSS and has following questions to ask SA WG2. As defined in clause 5.32.2 of TS 23.501, the UE provides the 'MA PDU Request' indication and its ATSSS capabilities to the SMF when UE requests to establish a MA PDU Session. As defined in clause 5.32.3 of TS 23.501, during the establishment of a MA PDU session, the PCF may take ATSSS policy decisions and create PCC rules that contain ATSSS policy control information. As defined in clause 4.22.2.1 step 7 of TS 23.502 (UE Requested MA-PDU Session Establishment), the SMF sends an 'MA PDU Request' indication to PCF in the SM Policy Control Create message. The PCF decides whether the MA PDU session is allowed or not based on operator policy and subscription data As defined in clause 4.22.3 step 7 of TS 23.502 (UE Requested PDU Session Establishment with Network Modification to MA-PDU Session), the SMF indicates to PCF that the SM policy control information is requested for a MA-PDU Session Q1: Are both, the 'MA PDU Request indication' and the 'UE ATSSS capabilities' information of a Multi Access PDU session relevant for the PCF? Q2: When does the SMF provide the MA PDU session relevant information above to the PCF? i.e., is it sent only and always at PDU session establishment? Or could it depend on whether the ATSSS procedure is UE Requested MA PDU Session Establishment or UE Requested PDU Session Establishment with Network Modification to a PDU Session? Q3: When the PCF decides that the MA PDU session is not allowed, what kind of policy decision would the PCF provide to the SMF, e.g. would the PCF reject the MA PDU session establishment? or would the PCF indicate that only single-access PDU session is allowed and provide the policy information without MA PDU Session Control information?. Action: CT WG3 asks SA WG2 to kindly answer the above questions and to consider clarifying their specifications in that respect.","secretary_remarks":"Postponed S2-1908647 from S2#135.

The UPF may use other Steering Modes to deliver DL traffic to the UE over the accesses based on N4 rules provided by the SMF. RTT Measurements must not be done using PMF messages. In essence, this addresses the EN by way of utilizing the Active-Standby Steering Mode for ATSSS-LL steering functionality to steer non-MPTCP traffic on the accesses. This leverages the existing ATSSS architecture by using the low-layer steering functionality (ATSSS-LL) coupled with the Active-Standby Steering Mode to indicate how non-MPTCP traffic should be distributed over the accesses, by both the UE and UPF. Because it is rule-based, it can also be dynamically updated by the network as needed.","secretary_remarks":"Revision of S2-1910782 from S2#135.

The UPF may use other Steering Modes to deliver DL traffic to the UE over the accesses based on N4 rules provided by the SMF. RTT Measurements must not be done using PMF messages. In essence, this addresses the EN by way of utilizing the Active-Standby Steering Mode for ATSSS-LL steering functionality to steer non-MPTCP traffic on the accesses. This leverages the existing ATSSS architecture by using the low-layer steering functionality (ATSSS-LL) coupled with the Active-Standby Steering Mode to indicate how non-MPTCP traffic should be distributed over the accesses, by both the UE and UPF. Because it is rule-based, it can also be dynamically updated by the network as needed.","secretary_remarks":"Revision of S2-1911779.

In particular, it specifies that the UE indicates to the network the steering functionalities supported for an MA PDU Session by including in its ATSSS Capability one of the following: ATSSS-LL functionality with any steering mode MPTCP functionality with any steering mode and ATSSS-LL functionality with only Active-Standby steering mode MPTCP functionality with any steering mode and ATSSS-LL functionality with any steering mode In addition, it is specified that the network may provide to UE the Measurement Assistance Information and shall provide to UE one or more ATSSS rules including an ATSSS rule for non-MPTCP traffic. The ATSSS rule for non-MPTCP traffic shall use the ATSSS-LL functionality and the Active-Standby Steering Mode to indicate how the non-MPTCP traffic shall be transferred across the 3GPP access and the non-3GPP access in the uplink direction.","secretary_remarks":"Revision of S2-1912493.
