Direct Wireless Link Supervision for Critical Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Critical wireless communication systems experience frequent communication breaks between devices under and outside network coverage, leading to critical transmission losses, as existing solutions fail to effectively manage communication discontinuity between devices in relayed and direct modes.
Innovation Solution
A critical wireless communication system comprising communication devices with unique identifiers, direct and relayed communication modules, and a supervision mechanism that monitors connectivity states and transmits connectivity messages through an interconnection network to maintain continuous communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dual terminals use relayed mode with network infrastructure connection, then communication reliability is improved under network coverage, but communication continuity deteriorates when moving outside network coverage areas
Solution Approach 1:
The system dynamically switches between relayed mode (when under network coverage) and direct mode (when outside coverage). Each terminal monitors its network connectivity status and automatically transitions communication mode to maintain continuity, making the system adaptable to changing environmental conditions rather than static in one mode
Solution Approach 2:
The network infrastructure acts as an intermediary for relayed communication when available, while direct wireless links serve as the intermediary when network infrastructure is unavailable. The system uses whichever intermediary is currently functional to maintain communication
2Duration of action of stationary object
If dual terminals use direct mode without network infrastructure, then communication continuity is improved outside network coverage, but communication reliability deteriorates under network coverage due to frequent breakdowns
Solution Approach 1:
The system dynamically selects between direct mode and relayed mode based on real-time network coverage conditions. When under network coverage, it uses relayed mode for higher reliability; when outside coverage, it switches to direct mode to maintain continuity
Solution Approach 2:
The system establishes direct communication links in advance between terminals before network coverage is lost, ensuring immediate continuity. Connectivity supervision mechanisms proactively monitor link status and trigger mode transitions before complete communication breakdown occurs
3Duration of action of stationary object
If the system implements supervision of direct communication links between devices, then communication discontinuity is reduced, but device complexity increases due to additional monitoring mechanisms
Solution Approach 1:
Each terminal autonomously performs connectivity supervision by monitoring its own direct communication links with other terminals. The system self-diagnoses link status and automatically triggers mode transitions without requiring external supervision infrastructure, reducing overall system complexity
Solution Approach 2:
The system implements feedback loops where terminals continuously monitor direct link connectivity status and use this feedback to automatically switch between direct and relayed modes. This closed-loop control maintains communication continuity through real-time adaptation to changing conditions

AI summary
A wireless communication system (10) is proposed, comprising a set of at least two communication devices (100). Each communication device (100-n) is associated with a unique identifier and includes a direct communication module (1060). The direct communication module is configured to receive one or more identified direct communication messages transmitted by one or more other communication devices (100-(n+1)) in said set (called transmitting devices).A communication device (100-n) is configured to determine the unique identifier for each transmitting device from the received identified message, to determine a direct connectivity state corresponding to a direct wireless communication link state of each of the transmitting devices with the communication device, and to determine an elementary connectivity matrix comprising the direct connectivity state associated with the unique identifier of each transmitting device.
