Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If machine type communication devices use traditional IP connections and PDP contexts for data transmission, then reliable communication can be established, but signalling overhead and network complexity increase significantly
Solution Approach 1:
The patent extracts machine type communication data transmission from the traditional IP connection framework. Instead of requiring full PDP context activation and IP bearer establishment, the invention uses a simplified signaling mechanism where MTC devices can transmit data directly using radio resource control signaling, eliminating the need for complex IP layer setup while maintaining reliable delivery through network acknowledgment mechanisms.
Solution Approach 2:
The patent segments the communication process into distinct phases: data transmission phase using simplified signaling separate from the traditional attachment and PDP activation phases. This allows MTC data to be handled independently from voice and general data traffic, reducing overall network complexity while preserving reliability for each traffic type.
2Reliability
If machine type communication devices activate PDP contexts and establish IP bearers for each communication session, then data can be transmitted reliably, but signalling overhead and bandwidth consumption increase
Solution Approach 1:
The patent merges MTC data transmission with existing radio resource control signaling structures already present in the network. By combining MTC data carriers with uplink synchronization signals and using existing random access channel resources, the invention eliminates the need for separate PDP context activation signaling, thereby reducing signaling overhead while maintaining reliable data delivery through integrated acknowledgment mechanisms.
Solution Approach 2:
The patent makes existing radio signaling structures universal by enabling them to carry both traditional control signaling and MTC data simultaneously. The random access channel and uplink synchronization signals are designed to serve multiple purposes: traditional cell selection, synchronization, and now also MTC data transmission, thereby eliminating the need for dedicated signaling resources and reducing overall signaling overhead.
3Adaptability or versatility
If traditional cellular access networks handle machine type communication traffic, then existing infrastructure can be used, but the networks become overloaded due to vast amounts of low bitrate traffic
Solution Approach 1:
The patent introduces a new dimension for MTC traffic handling by creating a separate signaling plane specifically for machine type communication. Instead of mixing MTC low-bitrate traffic with traditional voice and data traffic in the same signaling channels, the invention establishes dedicated MTC data carriers and signaling paths, allowing the network to handle MTC traffic in parallel without interfering with traditional services, thereby maintaining network efficiency while accommodating vast amounts of MTC traffic.
