After extensive offline discussions between SA WG2 and SA WG3 colleagues, a model comprised of the following characteristics emerged. The UPGF - is a security function, independent of the UPF, - may or may not be collocated with the UPF, - is a transparent proxy terminating neither N4 nor N9; enforcing GTP-U security between UPFs of the visited and home PLMNs, - can transparently extract GTP-U tunnel information from the N4 exchange between the SMF and the UPF. The attached CR S3-194443, to be included in TS33.501, reflects the above architectural principles. Action: SA WG3 kindly asks SA WG2 to take the above into account.","secretary_remarks":"Response drafted in S2-2001016.
