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.

Abstract: A primary authentication procedure is triggered to derive an authentication key for a home network. The authentication key may be used for interworking between network types. For example, a home network primary authentication mechanism may be triggered for interworking from Evolved Packet System (EPS) to 5GS. When a user equipment (UE) moves between network types, the security context and authentication may be different or incompatible. For example, an authentication key may be missing, which may be needed for authentication in one of the network types. Authentication key support may be determined and registration/authentication may vary based on that support. When there is no support for the authentication key, a reauthentication process may be performed.

Abstract: Presented are systems and methods for authorization of proximity based services. A first wireless communication device may send, to a second wireless communication device, a message to access a network via the second wireless communication device as a relay node, using at least one authentication and key management for applications (AKMA) service. The message may include an AKMA key identifier (A-KID) and a freshness parameter. The first wireless communication device may generate a validation token to validate against another validation token of the second wireless communication device. The first wireless communication device may generate the validation token using the freshness parameter and a proximity based service function (PBSF) key (KPBSF).

Abstract: 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.

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.
