RCPI Value Parsing for Accurate Multi-Vendor Roaming Decisions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless mesh networks, the parsing of Received Channel Power Indicator (RCPI) values from different manufacturers is inconsistent due to incompatible algorithms, leading to reduced accuracy and precision in terminal device roaming decisions.
Innovation Solution
A method is provided to determine an appropriate parsing algorithm for RCPI values by utilizing value intervals and non-overlapping blind areas in existing algorithms, allowing for compatible parsing of RCPI values from different definitions, thereby improving parsing accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two different algorithms for parsing RCPI values are used (one defined in IEEE 802.11k standard and one not), then different manufacturers can implement their own parsing methods, but the parsing accuracy and compatibility are reduced
Solution Approach 1:
The patent changes the parameter of parsing algorithm selection based on the value interval of RCPI. By detecting which interval the RCPI value falls into, the system dynamically selects the appropriate parsing algorithm (standard or non-standard), thereby maintaining both compatibility across different manufacturers and accuracy in parsing.
Solution Approach 2:
The patent segments the RCPI value range into different intervals, with each interval corresponding to a specific parsing algorithm. This segmentation allows the system to handle different manufacturer implementations by routing values to the appropriate algorithm based on their interval, resolving the contradiction between compatibility and accuracy.
2Adaptability or versatility
If RCPI values from different manufacturers based on incompatible algorithms are used, then more devices can be supported, but the precision of terminal device roaming decisions is reduced
Solution Approach 1:
The system changes the parsing parameter (algorithm selection) based on the RCPI value interval, enabling accurate interpretation of values from different manufacturers while maintaining support for multiple device types. This ensures both broad compatibility and high precision in roaming decisions.
Solution Approach 2:
The value interval detection acts as an intermediary mechanism that mediates between different manufacturer algorithms. By using the interval as a classifier, the system routes values to the correct parsing algorithm, ensuring accurate interpretation regardless of the original manufacturer's implementation.

AI summary
Disclosed are a parsing method for a received channel power indicator value, and a device and a storage medium. The parsing method for a received channel power indicator (RCPI) value comprises: sending, to a terminal, a measurement request for requesting to measure a connected signal strength (S101); receiving a measurement report, which is sent by the terminal on the basis of the measurement request, wherein the measurement report carries an RCPI value (S102); determining a corresponding parsing algorithm according to a value interval in which the RCPI value is located (S103); and parsing the RCPI value by using the determined parsing algorithm (S104).
