Hi @s5uishida,

traffic influence policy apply on PCF and PCF update the policy in SMF. SMF change the datapath of UE from UPF-1 to UPF-2 without dropping the session.
PCF accept the request and update the SMF. SMF will notify the UPF that traffic will move to access application server from UPF-2 and also notify the UE for N1N2 request that datapath of UE for new application server from PSA-UPF2.
