Question: What is the primary purpose of the MA-Information AVP (AVP code 570) in the context of Policy and Charging Control over Rx reference point?
Option 1: To convey additional or released IP-CAN type and RAT type for a Multi-Access (MA) PDU session.
Option 2: To manage Quality of Service (QoS) parameters for dedicated bearer resources.
Option 3: To authenticate User Equipment (UE) across different Radio Access Technologies (RATs).
Option 4: To report real-time network congestion to the Policy and Charging Rules Function (PCRF).
Explanation: The MA-Information AVP is specifically designed to carry information related to the IP Connectivity Access Network (IP-CAN) type and Radio Access Technology (RAT) type, which are crucial for managing Multi-Access PDU sessions. This aligns with the need for flexible and adaptive network management in heterogeneous network environments, where devices may simultaneously use multiple access technologies.
