Question: In a 3GPP EPS AAA interface utilizing the Diameter protocol over the SWx interface, what roles are recommended for the 3GPP AAA server and HSS when implementing IETF RFC 8583 for load control?
Option 1: 3GPP AAA server as a Reporting Node and HSS as a Reacting Node
Option 2: 3GPP AAA server as a Reacting Node and HSS as a Reporting Node
Option 3: Both 3GPP AAA server and HSS as Peer Nodes for mutual load control
Option 4: No specific roles are defined; implementation is vendor-specific
Explanation: According to guidelines for implementing IETF RFC 8583, the 3GPP AAA server should behave as a reacting node, responding to load control messages. The HSS should act as a reporting node, sending load information to manage Diameter overload, ensuring efficient network load management between these EPS components.
