    Abstract: 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.

    Abstract: 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.

    Abstract: 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.

    Abstract: 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.
