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.
