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: This disclosure generally relates performing UE authentication and registration with the core network, and in particular, to supporting secure interactions between the UE and the target AMF when the UE is re-allocated to the target AMF. During a UE registration procedure, the initial AMF generate a 5G-GUTI for the UE and retrieves a candidate AMF list. The initial AMF sends the generated 5G-GUTI (or 5G-S-TMSI), the candidate AMF list, and a full registration request message to the (R)AN for storage and subsequent use. The initial AMF, once determines an AMF re-allocation is needed, instruct the UE to re-start the registration procedure with the core network, by using the generated 5G-GUTI. The (R)AN selects the target AMF, and forward the stored full registration request message to the target AMF to complete the registration.
