name: AA
full_form: Authenticating Agent
context: in a web cafÃ© laptop, and the OP/NAF will not get any of the indications described in cases I and II above. In this case it is up to OP/NAF to decide which of the scenarios 1, 2 or 4 should be used. To differentiate between those, the OP/NAF may have AA capability available provided by other means ,e.g. directly by the user stored in a (user) profile or if the user has done the registration for GBA push as specified in GBA Push TS 33.223. For case III) the following scenarios are possible: the AA is not connected to the BA, then the following scenarios apply: - Scenario 1: AA is GBA push enabled and does not communicate directly with BA - Scenario 2 and 4: AA is GBA enabled, but not GBA push enabled and does not communicate directly with BA In case the AA is not connected to BA, the OP/NAF decides, based on its knowledge of AA capabilities, whether scenario 1, 2 or 4 should be performed. Recommended usage is to perform scenario 1 if supported by the AA.
description: The Authenticating Agent (AA) is a network function responsible for authenticating users and providing authentication information to other network functions, such as the Bootstrapping Server Function (BSF). It plays a crucial role in the Generic Bootstrapping Architecture (GBA) and GBA push mechanisms.
explanation: The AA is classified as a Network Function based on its role in authenticating users and interacting with other network functions, such as the BSF, to facilitate secure communication and bootstrapping processes.
