The present document relates to methods, systems, and devices related to digital communication, and more specifically, to techniques related to AUSF selection in the case of dual registrations in AKMA. One example data communication method includes receiving, by a first network function, a request to retrieve an identifier of a second network function that authenticated a terminal from a third function, the request including a parameter. The method also includes transmitting, by the first network function, a response to the third network function that includes the identifier of the second network function that authenticated the terminal that is identified based on the parameter.

Authentication server function selection in an authentication and key agreement

This disclosure generally relates to User Equipment (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 Access Management Functions (AMFs) belonging to different Public Land Mobile Networks (PLMNs).

Method, device, and system for authentication and authorization with edge data network

Methods, apparatus, and systems to establish a secure communication in a wireless network are described. In one example aspect, a wireless communication method includes generating, by a first function entity, a first identifier configured to be used to establish a secure communication for a first device, using at least a mobile country code, a mobile network code, and a random number, and transmitting the first identifier to the first device.

Parameters for application communication establishment

The present disclosure relates to a wireless communication method, systems and devices for a registration procedure. The wireless communication method for use in a wireless terminal includes determining a concealed identifier based on a permanent identifier and a check value. A message with the concealed identifier for a registration procedure is transmitted to a wireless network node.

Wireless communication method for registration procedure

This patent document describes, among other things, techniques, and apparatuses for providing onboarding and provisioning of networks. In one aspect, a method of wireless communication is disclosed. The method includes receiving, by a first network node from a second network node, an authentication notification including an identifier for a third network node where a key is stored. The method further includes transmitting, by a first network node, a wireless device parameter update message to the third network node identified by the identifier.

Control plane based security provisioning in a non-public network

A session request method, a session request apparatus, a terminal, and a storage medium are provided. The session request method includes: generating an authentication server key when a key agreement authentication is passed; determining, according to the authentication server key, a key identifier of an authentication and key management for applications (AKMA) anchor key; when the key identifier is invalid, updating the key identifier according to a mobile subscriber identification number (MSIN); and sending an updated key identifier to an application function, to request a key-based session.

Session request method and apparatus, terminal, and storage medium

This disclosure generally relates to encrypted communication between terminal devices and service applications via a communication network. Such encrypted communication may be based on various hierarchical levels of encryption keys that are generated and managed by the communication network. Such encrypted communication and key management may be provided by the communication network to the terminal devices as a service that can be subscribed to. The various levels of encryption keys may be managed to improve flexibility of the communication network and to reduce potential security breaches.

Method, device, and system for anchor key generation and management in a communication network for encrypted communication with service applications

Method, device, and system for application key generation and management in a communication network for encrypted communication with service applications

Presented are systems and methods for acquiring channel state information. A wireless communicate node may transmit a channel state information reference signal (CSI-RS) to a wireless communication device via a first antenna port of a plurality of antenna ports of the wireless communication node. The wireless communication node may receive a channel state information (CSI) report from the wireless communication device.

Registration with accessibility and mobility management function re-allocation

Method, systems and devices for wireless communication. The method includes protecting privacy of a transmitted network slice selection assistance information (NSSAI) between a user equipment and a base station. The method includes receiving a temporary NSSAI (T-NSSAI) from an access and mobility management function (AMF) to the base station, the T-NSSAI comprising at least one temporary single NSSAI (T-S-NSSAI) and storing the T-NSSAI in the base station. The method also includes receiving a radio resource control (RRC) signaling message from the user equipment to the base station, the RRC signaling message comprising a T-S-NSSAI corresponding to an allowed single NSSAI (S-NSSAI); and selecting the AMF based on the T-S-NSSAI.

Methods and devices for protecting privacy of slice identity information

The present disclosure describes methods, systems and devices for establishing secure communication between a user equipment and a service application in a wireless communication. One method includes receiving, by the user equipment, an authentication and key management for service applications identifier (AKMAID) from an authentication server function (AUSF) upon successful completion of an authentication process for registering the user equipment with the communication network. The method also includes storing, by the user equipment, the AKMAID; deriving, by the user equipment, an application key based on a base authentication key; sending, by the user equipment, a communication request to the service application, the communication request comprising the AKMAID; and receiving, by the user equipment, an application session establishment response to the communication request from the service application to establish a security communication session between the user equipment and the service application based on the application key.

Methods and devices for establishing secure communication for applications

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.
