name: NAF
full_form: Network Application Function
context: The NAF reads its available data associated with the user and the application for which the NAF SA shall be established. The NAF then determines the Ua security protocol identifier to use in the request to the BSF. It also determines the required life-time of the NAF SA. The NAF then generates the GPI request containing the parameters as given in table 5.1.2. . If the NAF has received an AUTS parameter and a RAND from the UE indicating that a synchronisation failure has occurred on the USIM when the UE processed the previous GPI, then the NAF shall use the RAND to identify the corresponding NAF SA for this particular UE and include the AUTS and the RAND in the new NAF GPI request to the BSF. If the NAF has received the RAND and AUTS protected via the Ua interface, the NAF may invalidate the NAF SA until it has received a new GPI response from the BSF . NOTE : Allowing the NAF to invalidate the NAF SA is Ua protocol specific. If the NAF invalidates the NAF SA when it receives the AUTS
description: The Network Application Function (NAF) manages and processes data related to user applications and security protocols in the 5G core network. It interacts with other network functions, like the Bootstrapping Server Function (BSF), to establish and manage NAF Security Associations (SA).
explanation: The text describes the NAF's responsibilities in managing data, handling security protocols, and interacting with other network components. These actions are typical of a Network Function, which is designed to control and manage specific aspects of network operations.
