Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If remote interference management mechanisms are implemented to improve network robustness, then interference mitigation capability is improved, but device complexity and signaling overhead increase
Solution Approach 1:
The patent introduces a Remote Interference Management Function (RIMF) as an intermediary entity that centralizes interference management tasks. This mediator coordinates between base stations, handles profile generation and matching, and manages the complex signaling procedures, thereby improving network robustness while containing individual device complexity through functional specialization.
Solution Approach 2:
The RIM profile serves multiple functions: it identifies interfering base stations, characterizes interference patterns, enables coordination between operators, and supports both detection and mitigation actions. This multi-functionality reduces the need for separate mechanisms, balancing reliability improvement against complexity increase.
2Measurement precision
If comprehensive physical and logical attributes are gathered to determine interference profiles, then measurement precision is improved, but loss of time and signaling overhead increase
Solution Approach 1:
The patent performs preliminary actions by pre-defining RIM profiles with expected interference patterns and characteristics before actual interference occurs. Base stations can match incoming interference against these pre-prepared profiles, reducing the time needed for analysis while maintaining detection accuracy through comprehensive attribute gathering.
Solution Approach 2:
The system gathers comprehensive attributes (excessive action) to create detailed profiles, but in practice, only the most relevant matching attributes need to be processed for each interference event. This allows high measurement precision for profile creation while reducing processing time during actual interference mitigation through selective attribute evaluation.
3Reliability
If blockchain technology is implemented for secure and auditable interference management, then reliability and security are improved, but device complexity and processing overhead increase
Solution Approach 1:
The blockchain functions as a decentralized mediator that provides secure, immutable recording of interference management actions and profile matches. By using blockchain for logging and coordination rather than for real-time control decisions, the system achieves enhanced security and auditability while minimizing the complexity impact on individual network elements.
4Productivity
If remote interference management actions are performed to mitigate interference, then network efficiency is improved, but loss of time and signaling overhead increase
Solution Approach 1:
The system prepares RIM profiles and identifies potential interfering base stations in advance through continuous monitoring and attribute gathering. When interference is detected, pre-configured mitigation actions can be executed rapidly by matching the situation against predefined profiles, improving network efficiency while reducing the time required for real-time decision-making.
