Question: In a 3GPP-compliant Packet Switched Streaming Service, what is a key characteristic of how the streaming service interacts with the Public Land Mobile Network (PLMN)?
Option 1: The PLMN actively manages the initiation and execution of the streaming service.
Option 2: The interaction follows a client/server model that is transparent to the PLMN, with the client controlling initiation and execution.
Option 3: The streaming service requires a dedicated circuit-switched connection within the PLMN for quality assurance.
Option 4: The PLMN dynamically adjusts Quality of Service (QoS) parameters based on real-time network congestion for all streaming services.
Explanation: This is correct because, as per the service principles for Packet Switched Streaming, the client/server model is specified to be transparent to the PLMN, indicating that the control and management of the streaming session are handled by the client, without requiring direct PLMN intervention in the initiation or execution process. This aligns with typical IP-based service architectures where end-user devices (clients) interact directly with servers for content delivery, leveraging existing network infrastructure (in this case, the PS Domain) for connectivity.
