Core Network Rerouting for RFID-Cellular Channel Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Interference and communication failures occur when mobile devices attempt to perform both RFID and cellular communications over the same frequency channel, leading to dropped calls, messages, and decreased network capacity.
Innovation Solution
A core network system performs interference mitigation actions by temporarily caching or rerouting cellular communications when a mobile device initiates RFID communications, using policies and configurations to manage frequency channels and prevent simultaneous communication on the same channel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If mobile devices perform both RFID and cellular communications over the same frequency channel, then communication versatility is improved, but communication reliability deteriorates due to interference and dropped calls
Solution Approach 1:
The system dynamically switches cellular communications between frequency channels based on RFID communication needs. When RFID communication is detected on a frequency channel, the core network automatically reroutes cellular communications to a different frequency channel, and restores the original channel when RFID communication ends. This dynamic adaptation resolves the contradiction by making the cellular communication frequency flexible rather than fixed.
Solution Approach 2:
The system changes the frequency channel parameter of cellular communications in response to RFID communication requirements. The core network monitors RFID communication status and modifies the frequency channel parameter of cellular communications accordingly, switching between available frequency channels to avoid interference while maintaining both communication types.
2Adaptability or versatility
If mobile devices perform RFID communications over cellular frequency channels, then device functionality is improved, but network capacity deteriorates due to communication failures
Solution Approach 1:
The system dynamically adjusts network resource allocation by switching frequency channels based on real-time communication needs. When RFID communication is active, cellular communications are dynamically rerouted to different frequency channels, preventing interference and maintaining network throughput. This dynamic resource management preserves network capacity while enabling enhanced device functionality.
Solution Approach 2:
The core network acts as an intermediary that manages frequency channel allocation between RFID and cellular communications. It monitors communication status, detects interference conditions, and automatically reroutes cellular communications through alternative frequency channels, mediating between the two communication types to maintain overall network capacity.
3Reliability
If cellular communications are rerouted to another frequency channel during RFID communication, then communication interference is reduced, but system complexity increases
Solution Approach 1:
The core network performs automatic frequency channel management without requiring complex client-side implementation in mobile devices. The system self-monitors RFID communication status through standardized protocols and autonomously decides when and how to reroute cellular communications, reducing the complexity burden on mobile devices while maintaining high communication reliability.
Solution Approach 2:
The system implements a feedback mechanism where the core network continuously monitors RFID communication status and uses this information to automatically adjust cellular communication frequency channels. This closed-loop feedback control enables reliable interference avoidance through systematic frequency management without requiring complex predictive algorithms or manual configuration.

AI summary
A core network is configured to receive a first message indicative of a trigger event at a mobile device, in which the trigger event occurs when the mobile device is initiating an RFID communication with an RFID tag over a frequency channel, in which the mobile device is also configured to communicate with a cell site associated with the core network over the frequency channel, and perform an interference mitigation action on a cellular communication destined for the mobile device over the frequency channel, in which the interference mitigation action comprises temporarily caching the cellular communication destined for the mobile device over the frequency channel or rerouting the cellular communication destined for the mobile device over another frequency channel.
