Semantic Broker
Semantic Knowledge Broker and Context Plane
A 6G core plane function that manages semantic knowledge bases, ontologies, and context models to enable meaning-based data transmission.
Technical Explanation
In traditional telecom networks, bits are transmitted irrespective of their semantic meaning. The 6G Semantic Broker introduces a dedicated Context & Semantic Plane. It maintains shared knowledge graphs and ontologies between senders and receivers. Rather than transmitting raw high-resolution video or lidar point clouds, senders transmit semantic symbols that the receiver reconstructs using the broker's synchronized world model, slashing bandwidth consumption by up to 99%.
Key Functions
- Synchronization of shared semantic knowledge bases and domain ontologies
- Goal-oriented data compression and semantic context translation
- Extraction and indexing of semantic concepts from raw sensor and camera streams
- Dynamic schema adaptation based on user intent and channel state
- Drastic reduction of transmission bandwidth for autonomous vehicle and digital twin telemetry
