Abstract: A User Equipment (UE), network-side device, system and method are disclosed for external authentication using an Extensible Authentication Protocol (EAP). The method includes, when the UE is initially attached to an Evolved Packet System (EPS) network via an Evolved UMTS Terrestrial Radio Access Network (E-UTRAN), the UE transmitting EAP authentication information required for the EAP authentication to a packet data network gateway and, after receiving EAP request, the UE transmitting a bearing resource modification request message carrying EAP response to the packet data network gateway. With the method, the UE can use the EAP authentication to implement authentication and authorization by an external authentication and authorization server via a GGSN/PDN GW in a process of connecting the UE to the EPS via a 3GPP access.

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. During a UE registration procedure, the initial AMF generate a 5G-GUTI for the UE and retrieves a candidate AMF list. The initial AMF sends the generated 5G-GUTI (or 5G-S-TMSI), the candidate AMF list, and a full registration request message to the (R)AN for storage and subsequent use. The initial AMF, once determines an AMF re-allocation is needed, instruct the UE to re-start the registration procedure with the core network, by using the generated 5G-GUTI. The (R)AN selects the target AMF, and forward the stored full registration request message to the target AMF to complete the registration.
