context: packets, into PPP packets, etc. The UE provides a NAI that triggers the TNAP to send an AAA request to a TNGF-CP, which operates as an AAA proxy. Between the TNAP and TNGF-CP the EAP packets are encapsulated into AAA messages. 4-10. An EAP-5G procedure is executed as specified in TS 33.501 [3], clause 7.2.1with the following modifications: - The EAP-5G packets are not encapsulated into IKEv2 packets. - A TNGF key and a TNAP key (instead of an N3IWF key) is created in the UE and in the AMF and TNGF-CP respectively after the successful authentication. The TNGF key is transferred from the AMF to TNGF-CP in step 10a (within the N2 Initial Context Setup Request). The TNGF-CP generates the TNAP key and transfers it from TNGF-CP to TNAP in step 10b (within an AAA message). In case of trusted WLAN access, the TNAP key corresponds to the Pairwise Master Key (PMK) and can be derived from the TNGF key, e.g. by using the first 32 bytes of the TNGF key. - In step 9b the UE receives the "TNGF
description: A Trusted Non-3GPP Access Point (TNAP) is a network function that provides access to the 5G core network for non-3GPP devices, such as WLAN or Wi-Fi. It acts as an intermediary between the UE and the TNGF-CP, facilitating authentication and key exchange.
explanation: The context describes TNAP's role in handling AAA requests, encapsulating EAP packets into AAA messages, and generating keys for secure communication. This functionality aligns with the definition of a Network Function, which includes components that manage access and mobility within the network.
