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
