Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face inefficiencies in monitoring and maintaining reliable connectivity for Machine-to-Machine (M2M) communications, leading to potential failures and high labor costs due to over-dimensioning and redundancy measures, which are not dynamically adapted to changing connectivity needs.
Innovation Solution
A method and system where a wireless device dynamically adjusts the number of probe messages based on the required and estimated levels of connectivity, reducing power consumption and network resource usage by sending fewer probe messages when connectivity is above the required level, and increasing them when it falls below the threshold.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the radio access network is over-dimensioned with redundant resources and multiple base stations to ensure high reliability for M2M devices, then the reliability and availability of wireless connectivity is improved, but the deployment cost, network complexity, and resource consumption increase significantly
Solution Approach 1:
The patent implements dynamic probe message adjustment where the wireless device adapts the number and frequency of probe messages based on real-time connectivity conditions. When connectivity is good, probe messages are reduced; when connectivity degrades, probe messages are increased. This dynamic approach replaces static over-dimensioning with adaptive monitoring, reducing unnecessary network resources while maintaining reliability.
Solution Approach 2:
The patent changes the parameter of probe message frequency and quantity based on measured connectivity quality. By adjusting this parameter dynamically, the system achieves reliable connectivity monitoring without requiring permanent over-dimensioned network infrastructure, thus reducing deployment complexity while maintaining reliability.
2Reliability
If multiple probe messages are continuously sent to verify connectivity for M2M devices, then the reliability of connectivity monitoring is improved, but the power consumption and network resource usage increase
Solution Approach 1:
The patent implements periodic probe message transmission with variable intervals. Instead of continuous probing, the system sends probe messages at periodic intervals that are dynamically adjusted based on connectivity conditions. When connectivity is stable, intervals are extended; when connectivity degrades, intervals are shortened. This periodic action reduces power consumption while maintaining reliable connectivity verification.
Solution Approach 2:
The patent makes the probe message transmission dynamic by adjusting the number and frequency of probe messages based on real-time connectivity assessment. This dynamic adaptation allows the system to reduce power consumption during good connectivity conditions while maintaining reliable monitoring when needed, resolving the contradiction between verification reliability and energy usage.
3Reliability
If manual restoration or replacement of M2M devices is performed when communication failures occur, then the service reliability is restored, but the labor costs and response time increase significantly
Solution Approach 1:
The patent implements preliminary detection of connectivity degradation through continuous probe message monitoring. By detecting connectivity issues before complete service failure occurs, the system can trigger pre-configured restoration actions or alert maintenance personnel in advance, reducing both restoration time and labor costs compared to reactive manual intervention after complete failure.
Solution Approach 2:
The patent establishes a feedback mechanism where probe message responses provide continuous information about connectivity status. This feedback loop enables early detection of degradation trends, allowing for proactive service restoration measures before complete failure, thereby reducing restoration time and manual intervention requirements.
4Reliability
If redundancy measures such as multiple power units and backup nodes are deployed to increase node availability, then the reliability of network operation is improved, but the deployment cost and device complexity increase
Solution Approach 1:
The patent implements self-service connectivity monitoring where the wireless device itself performs probe messages to verify its own connectivity status. This eliminates the need for complex network-side monitoring infrastructure and redundant control nodes, achieving reliable availability monitoring through the device's own resources without increasing network deployment complexity.
