Question: What happens to an ongoing MBMS (Multimedia Broadcast/Multicast Service) session on a User Equipment (UE) in GERAN (GSM/EDGE Radio Access Network) when it responds to PS (Packet Switched) paging?
Option 1: The UE seamlessly switches to a dedicated channel for the MT (Mobile Terminating) PS data.
Option 2: The MBMS session continues uninterrupted, with the PS data delivered on a separate bearer.
Option 3: The UE rejects the PS paging to prioritize the ongoing MBMS session.
Option 4: The ongoing MBMS service is likely to be interrupted in the UE.
Explanation: In GERAN, responding to PS paging during an MBMS session typically requires a transition out of idle/broadcast reception mode. This can interrupt the MBMS service as the UE shifts from receiving broadcast data to point-to-point communication for packet-switched data, highlighting a trade-off between these services in legacy networks like GERAN.
