Abstract: This disclosure generally relates performing UE authentication and registration with the core network, and in particular, to supporting secure interactions between the UE and the target AMF when the UE is re-allocated to the target AMF. After the UE initiates a first registration request, the initial AMF may retrieve a candidate AMF list and selects a target AMF to serve the UE. The initial AMF generates a 5G-GUTI for the UE, based on the selected target AMF. The initial AMF requests the UE to initiate a second registration request, by using the generated 5G-GUTI. With the solutions provided in this disclosure, the message interactions between the UE and the target AMF are integrity protected and/or ciphered, without the need to upgrade the UE and without using an indirect connection of the core network.
