Question: In a UTRAN Iu interface, what type(s) of traffic classes are represented by the Real Time (RT) Load Value in terms of their contribution to the load?
Option 1: Interactive and Background traffic classes
Option 2: Conversational and Streaming traffic classes
Option 3: Only Conversational traffic class
Option 4: All traffic classes (Conversational, Streaming, Interactive, Background)
Explanation: The RT Load Value specifically pertains to the load generated by Real Time traffic. According to telecom principles, Real Time traffic is associated with Conversational (e.g., voice calls) and Streaming (e.g., video streaming) traffic classes, which require low latency and jitter, distinct from Interactive and Background classes.
