[{"name":"S2-2105240","title":"LS from CT WG4: LS on UPF support for multiple network slices","source":"CT WG4","contact":"Zhijun Li","contact-id":39295,"tdoctype":"LS in","for":"Action","abstract":"CT WG4 is discussing support by UPF of multiple network slices, as part of WI BEPoP (BEst Practice of PFCP). Per existing 3GPP TS 23.501 and 3GPP TS 29.244, the UP resources (e.g. UE IP addresses, GTP-U F-TEIDs, CPU, memory, bandwidth, etc.) are managed \/ allocated in the UPF per Network Instance (i.e. when establishing a PFCP session, the SMF indicates the Network Instance ID associated to the PDU session). The Network Instance can correspond to a transport network with distinct transport characteristics, e.g. transport network slice, support of UE IP Address allocation (with certain UE IP Address range), IP routes and routing protocol (OSPF, BGP) to receive DL packet over SGi\/N6, different routing engine or L2\/L3 technology (e.g. IPsec, UDP\/IP tunnel, MPLS, L2TP ) to separate the traffic (e.g. to support different network slices). For a given PDU session, the Network Instance used for the corresponding PFCP session is determined by the SMF based on many factors, e.g. DNN\/APN, S-NSSAI, 5G-VN, roaming status, location, subscribed UE IP Address Pool IDs, DNAI(s) for certain applications. In order to support various business scenarios where one UPF is shared by several customers while each customer may be allocated with one network slice, operators expect that one UPF shall be able to support multiple network slices, and thus UPF shall be able to manage UP resources at per network slice granularity. To support the possibility for a UPF to reserve and assign resources to PFCP sessions per network slice, CT WG4 has discussed the following two solutions: - Solution 1: This is the existing solution described above, where the SMF maps the S-NSSAI and other factors to a Network Instance ID and the UPF just uses the Network Instance for UP resource management, as described in TR 29.820 clause 6.3. This solution requires the SMF to map one S-NSSAI to specific Network Instance(s). If one UPF supports multiple network slices, it requires that each network slice has a mapped Network Instance. There is the opinion from some operators that such a solution requires a careful and more complex planning of the Network Instance and the slices, thus it reduces its flexibility. - Solution 2: The UPF uses the S-NSSAI in addition to the Network Instance ID to manage the UP resources, as described in TR 29.820 clause 6.9 (solution#9) and C4-212114 (Postponed). In existing TS 29.244, the S-NSSAI can already be provided by the SMF to the UPF (in a standalone S-NSSAI IE), but this has been intended for performance measurements (SA WG5 PM requirements). This solution requires the UPF to perform UP resource management (e.g. UP resource separation, UP resource allocation, UP resource usage report, etc.) using the S-NSSAI together with Network Instance, which is not yet supported by TS 29.244. This solution requires some configuration\/logic in the UP function to manage UP resources using the S-NSSAI together with the Network Instance information, and the CP function may then possibly select the Network Instance without considering the S-NSSAI of the PDU session, but it doesn't require the operator to configure a separate Network Instance for each network slice (e.g. when multiple 5GS slices would be mapped to the same transport slice), and managing UP resources at slice granularity looks natural when network slice is used. Some operators believe it provides flexibility to fulfil the requirement of various business scenarios and different implementations. During the discussion, some companies believe that selecting the right Network Instance to provision PDRs\/FARs for a PFCP session (i.e. a PDU session or a PDN connection) shall be part of the Control Plane Node (e.g. SMF\/PGW-C) functionality, and the SMF\/PGW-C is the network function which has full information related to a PDU session\/PDN connection. Requiring the UP function to use S-NSSAI together with Network Instance to manage the UP resources in the UPF may have architecture impacts (e.g. network slice","secretary_remarks":"Revision of postponed S2-2103766 from S2-145E.

SA WG3 would like to provide the following feedback: For protection of the information transferred from the CP function to the UP function, a security mechanism shall be used. According to TS 33.501, clause 9.9, and TS 33.401, clause 11, NDS\/IP as specified in TS 33.210 is the existing security mechanism for the N4 interface and the Sxb interface. NDS\/IP shall be used unless security is provided by other means, e.g. physical security. The existing mechanism NDS\/IP is sufficient to protect usernames and passwords on the N4 and Sxb interfaces, since it already provides confidentiality, integrity and replay protection.
