Question: What is a key benefit of an MBMS-aware client supporting simultaneous broadcast with unicast fallback in terms of network transitions?
Option 1: Enhanced Quality of Service (QoS) for real-time streaming
Option 2: Reduced signaling overhead during handovers
Option 3: Seamless transition between different access networks (e.g., from WiFi to cellular) during an ongoing session
Option 4: Increased security for multicast content transmission
Explanation: Supporting simultaneous broadcast with unicast fallback allows MBMS-aware clients to smoothly transition between different network domains (such as moving from a WiFi network to a cellular network) without interrupting the ongoing multimedia presentation, ensuring continuity of service. This is particularly beneficial in scenarios where coverage or connectivity necessitates a switch between networks during a session.
