Question: When converting a Diameter Response to a RADIUS Response on the Wa reference point, how does the 3GPP AAA Proxy Translation Agent handle a Diameter Response containing EAP frames?
Option 1: It translates the Diameter-EAP-Answer command into a RADIUS Accounting-Request command.
Option 2: It translates the Diameter-EAP-Answer command into a RADIUS Access-Accept/Reject/Challenge command, following IETF guidelines.
Option 3: It ignores EAP frames and only translates non-EAP related AVPs.
Option 4: It sends an error message to the WLAN AN indicating EAP frame conversion is not supported.
Explanation: When handling Diameter Responses with EAP frames for translation into RADIUS Responses, the 3GPP AAA Proxy Translation Agent must follow specific guidelines. According to the described process, which aligns with IETF guidelines, the correct action involves translating the Diameter-EAP-Answer command into a corresponding RADIUS Access-Accept, Reject, or Challenge command, depending on the context of the EAP frame.
