context: be invoked by the API Invoker related to the UE ID), and Oauth access token i.e. AEF Access token (to authorize the API invoker to request the service API invocation from AEF) to the AEF over CAPIF-3 reference point. The CCF can provide the remaining validity timer value for the AEF Key (i.e. AEFPSK) as in TS 33.122 Clause 6.5.2.1 [5]. Alternatively, the service information and access token sending can be skipped as it can be bound to the access token as claims (later received in step 13a) from the API invoker. 12. After fetching the relevant AEF Key for the authentication, the AEF can send Authentication Initiation Response message to API invoker to initiate the TLS session establishment. The AEF starts the validity timer based on the value received from the CAPIF core function in step 11. The API Invoker and the AEF can perform mutual authentication using the AEF key and establish TLS session. 13a. The API invoker can send Invocation service request to the AEF which can include
description: The Additional Elementary Functions (AEF) is a network function responsible for handling authentication, authorization, and invocation of services within the 5G core network. It interacts with other network functions such as the API Invoker and CCF to manage access tokens, authenticate users, and establish secure TLS sessions.
explanation: The context describes AEF's responsibilities in managing authentication, authorization, and service invocation within the 5G core network, which are key functions of a Network Function as defined by 3GPP standards.
