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

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.

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.

Subscription data update method and apparatus, node, and storage medium

Embodiments of the prevent invention provide a network access authentication method and device. The method comprises: receiving an authentication request message sent by a first serving network, wherein the authentication request message carries a user equipment pseudonym identifier generated by a user equipment; determining whether a local user equipment pseudonym identifier is asynchronous with the user equipment pseudonym identifier generated by the user equipment; and obtaining, if the determination result is yes, an encrypted international mobile subscriber identity (IMSI) to carry out network access authentication on the user equipment. The embodiments of the present invention can solve the problem that a network access process in the related art does not provide a processing method for the case where the user equipment pseudonym identifier in the user equipment is asynchronous with the user equipment pseudonym identifier in a home network.

Network access authentication method and device

proviced is an authentication method based on a GBA, and the method includes: a BSF receives an initialization request message sent by a UE, wherein the initialization request message carries a first identifier of the UE, and the first identifier comprises at least one of the following: a SUCI, an identifier converted from the SUCI, and a TMPI associated with the subscriber identity; the BSF acquires an AV of the UE according to the first ID; the BSF completes GBA authentication with the UE according to the acquired AV. In this way, the privacy of the SUPI is protected for the UE, and the SUCI or the identifier converted from the SUCI is used to perform the bootstrapping process of the GBA, thereby improving the security of the GBA authentication process.

Authentication method based on GBA, and device thereof

A system and method of registration with AMF re-allocation. The system and method includes receiving, by an initial AMF from a wireless communication device via a RAN, a registration request comprising a first device identifier associated with the wireless communication device. The system and method includes determining, by the initial AMF, an identifier type associated with the first device identifier. The system and method includes generating, by the initial AMF, a reroute message comprising a second device identifier. The system and method includes originating, by the initial AMF to the wireless communication device, a security mode command message comprising a redirection criteria or an integrity negotiation algorithm, the security mode command message causes the wireless communication device to set the redirection criteria allowing the wireless communication device to accept a request message that is not integrity protected and return a security mode complete message to the initial AMF.

Method of registration with access and mobility management function re-allocation

Embodiments of the prevent disclosure provide a network access authentication method and device. The method includes: receiving an authentication request message sent by a first serving network, the authentication request message carrying a user equipment alias identifier generated by user equipment; determining whether a local user equipment alias identifier is asynchronous with the user equipment alias identifier generated by the user equipment; and when the determination result is positive, obtaining an encrypted International Mobile Subscriber Identification Number IMSI for performing network access authentication on the user equipment.

The present disclosure discloses a near field communication discovery method, apparatus and system. Herein, the method includes: a discovery terminal receiving discovery information allocated by a network side to a discovered terminal, herein the discovery information includes a discovery identity, and the discovery information is transmitted by the network side to the discovered terminal; the discovery terminal performing paging or broadcasting using the discovery identity; and the discovery terminal receiving a response returned by the discovered terminal to determine that the discovered terminal is discovered.

The present invention discloses a home NodeB access method comprising: during initialization, a home NodeB access point selecting a home NodeB gateway connected to one of core networks which the home NodeB access point has right to access as a serving home NodeB gateway; the home NodeB access point registering in the serving home NodeB gateway, registering user information with the serving home NodeB gateway after receiving a non-access layer message sent from a user equipment, and forwarding the non-access layer message to the serving home NodeB gateway; and the serving home NodeB gateway forwarding the non-access layer message to a core network corresponding to a network access identifier of the user equipment according to the identifier after receiving the non-access layer message; and the core network interacting with the user equipment to complete access of the user equipment; so as to achieve share of the home NodeB.

Home base station access method, home base station system and home base station access point

The present invention discloses an emergency service handover method which is applied in a single radio voice service system. A UE has established an emergency session between an IMS domain and an emergency call center via LTE/SAE network, wherein the emergency session is anchored to a service centralization and continuity application server, SCC AS, at a visited location. When MSC obtains information that the UE having established the emergency session needs to be switched to a CS domain, an enhanced MSC initiates a session establishment request to the visited SCC AS for performing a handover from the IMS domain to the CS domain on a service layer.

Emergency service handover method
