In one exemplary aspect, a method for wireless communication includes transmitting an authentication message from a network node. The method also includes determining a failure value indicating a reason for failure of the authentication message. The method also includes encrypting the failure value and an identifier. The method also includes transmitting an encrypted response message to the network node. In another exemplary aspect, a method for wireless communication includes transmitting an authentication message to a terminal. The method also includes receiving an encrypted response message from the terminal. The method also includes decrypting the encrypted response message to determine the failure value and the indicator.

    Abstract: A method for attaching user equipment, UE, with a network slice supported by one or more network entities is described herein. A user parameter and subscriber-related information identifying the UE are sent from the UE to at least one of the one or more network entities. A network parameter is sent to the UE. A temporary network slice identifier is generated at (i) the UE and at (ii) at least one of the one or more network entities for use in attaching the UE to the network slice. The temporary network slice identifier is generated based on (a) the user parameter, (b) the network parameter, and (c) subscriber-related information. The temporary network slice identifier generated at the UE may be identical to the temporary network slice identifier generated at the at least one network entity.

    Abstract: 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.

    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: 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.
