RCPI Value Parsing by Interval for Cross-Manufacturer Roaming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless mesh networks, the incompatibility between different algorithms for parsing Received Channel Power Indicator (RCPI) values from various manufacturers reduces the accuracy of roaming decisions in terminal devices.
Innovation Solution
A method is provided to determine an appropriate parsing algorithm for RCPI values by utilizing non-overlapping 'blind areas' or unreasonable intervals in existing algorithms, using an either/or exclusion method based on the value interval of the RCPI, enabling compatible parsing of RCPI values from different definitions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple different algorithms for parsing RCPI values are used by terminal devices from different manufacturers, then device compatibility and manufacturing flexibility are improved, but parsing accuracy and roaming decision precision deteriorate
Solution Approach 1:
The patent changes the parameter of parsing algorithm selection based on the RCPI value range. Different parsing algorithms are applied depending on which interval the RCPI value falls into, allowing the system to adapt to different value ranges while maintaining high accuracy. This resolves the contradiction by making the parsing process parameter-dependent rather than manufacturer-dependent.
Solution Approach 2:
The patent segments the RCPI value range into multiple intervals, with each interval corresponding to a specific parsing algorithm. By dividing the overall value range into distinct segments, the system can apply the most appropriate algorithm for each segment, improving overall parsing accuracy while maintaining compatibility across different devices.
2Ease of manufacture
If manufacturer-specific parsing algorithms are used, then manufacturing flexibility is improved, but roaming decision reliability deteriorates
Solution Approach 1:
The patent creates a universal parsing mechanism that works across all terminal devices regardless of manufacturer. By using RCPI value intervals as the basis for algorithm selection rather than manufacturer identification, the system achieves multi-functionality that covers all devices while ensuring consistent and reliable roaming decisions network-wide.
Solution Approach 2:
The patent introduces RCPI value intervals as an intermediary that mediates between manufacturer-specific implementations and network-wide consistency. This intermediary layer allows different manufacturers to use different algorithms while the network controller can reliably determine which algorithm to apply based on the value interval, ensuring consistent roaming decisions.
3Measurement precision
If RCPI value parsing accuracy is improved through standardized algorithms, then roaming decision precision is improved, but adaptability to different manufacturer implementations deteriorates
Solution Approach 1:
The patent makes the parsing algorithm dynamic by selecting different algorithms based on the RCPI value interval. Rather than using a fixed standardized algorithm for all cases, the system dynamically adapts the parsing method to match the characteristics of the specific RCPI value range, maintaining both accuracy and compatibility.
Data Source
AI summary
A method for parsing a Received Channel Power Indicator (RCPI) value, a device and a storage medium are disclosed. The method for parsing a RCPI value may include: sending a measurement request for measuring strength of a connected signal to a terminal device; receiving a measurement report sent by the terminal device based on the measurement request, where the measurement report carries an RCPI value; determining a corresponding parsing algorithm according to a value interval in which the RCPI value is located; and parsing the RCPI value by utilizing the determined parsing algorithm.
