Base Station Proxy Video Frame Classification

The patent applies local quality by treating different video frame types (I-frames, P-frames, B-frames) with different priority levels. The scheduler assigns specific priority values to each frame type based on their importance for video decoding, allowing critical I-frames to receive preferential resource allocation while less critical B-frames receive lower priority. This resolves the contradiction by enabling fine-grained differentiation within the QoS framework, improving both reliability for critical frames and overall system productivity through optimized resource distribution.

The patent implements preliminary action by pre-defining priority levels for different video frame types before the actual scheduling process. The system establishes a priority mapping where I-frames are assigned highest priority, P-frames medium priority, and B-frames lowest priority. This pre-configured priority structure allows the scheduler to make rapid decisions during high traffic loads without complex real-time analysis, maintaining low device complexity while ensuring QoS reliability through predetermined differentiated treatment of frame types.

The patent applies parameter changes by modifying the scheduling decision parameter from uniform treatment to frame-type-specific priority values. The scheduler uses the frame type identifier (already present in the packet header) to select the appropriate priority level, changing the scheduling parameter dynamically based on frame type rather than using a fixed algorithm. This approach reduces delivery delay for critical frames while keeping scheduler complexity manageable by leveraging existing packet metadata.
