Question: Under which of the following scenarios is a UE policy association **NOT** required to be established?
Option 1: During UE initial registration with the network when a UE Policy Container is received.
Option 2: When the UE requests a PDU Session Establishment for SM policy association.
Option 3: When the AMF relocation occurs without a PCF change in an intra-AMF handover procedure.
Option 4: When the UE moves from EPS to 5GS and there is an existing UE Policy Association between AMF and PCF for this UE.
Explanation: A UE policy association needs to be established in scenarios involving initial registration with a UE Policy Container, AMF relocation with PCF change, or when moving from EPS to 5GS without an existing association. However, if the AMF relocation occurs **without** a PCF change (as specified in an intra-AMF handover procedure), there is no mentioned requirement for establishing a new UE policy association.
