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.

Abstract: Provided are a subscription data update method and apparatus, a node, and a storage medium, where the method includes: in a case where a first network function node determines that authentication and key management for applications (AKMA) subscription data of a user is updated, determining, by the first network function node, a second network function node storing an AKMA context of the user; sending, by the first network function node, a subscription data management notification message to the second network function node; and receiving, by the first network function node, a subscription data management notification response message sent by the second network function node; where the subscription data management notification response message is sent after the second network function node deletes the AKMA context of the user according to the subscription data management notification message.

Abstract: This disclosure generally relates to securely pushing messages from an AF to a User Equipment (UE) in communication networks. Performed by a wireless device in a wireless network, the method includes receiving, from a first network element hosting an Application Function (AF), a message comprising one of: an AKMA (Authentication and Key Management for Applications) key identifier (ID) identifying an AKMA anchor key of the wireless device; or a set of parameters indicative of the AKMA key ID; and storing the AKMA key ID and an AF key associated with the first network element in a security context, wherein the first network element outside of a core network of the wireless network.

Abstract: This disclosure generally relates to UE authentication and authorization with an edge data network in communication networks. Such authentication and authorization may be based on the generation and application of an edge computing key for a UE. Such edge computing key may be used for bi-directional authentication and may be dynamically updated during various stages of the authentication and authorization process. The authentication and authorization supports a UE connected to multiple AMFs belonging to different PLMNs.
