Solution Overview

Problem

The efficiency of determining the right to speak in communication systems is low, especially when multiple Secondary Protective Devices (SPDs) attempt to send information simultaneously, leading to frequent rejection of Request to Send (RTS) sequences and poor user satisfaction.

Innovation Solution

Implementing a system where each Secondary Protective Device selects a unique Request to Send (RTS) sequence from a preconfigured set and sends it to a Primary Protective Device (PPD), which chooses and sends a distinct RTS sequence to all SPDs, ensuring that each SPD's RTS sequence is almost different from others, thereby improving the determination of the right to speak.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple SPDs send RTS sequences simultaneously using the same content, then the PPD can identify each request, but all RTS sequences are rejected causing low efficiency in determining the right to speak

Engineering Contradiction:
Improveefficiency of determining the right to speakVSAvoidsuccess rate of RTS sequence acceptance
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent segments the identical RTS sequence content into multiple distinct sequences by introducing different sequence identifiers (SEQ IDs) for each SPD. Instead of all SPDs using the same RTS content, each SPD is assigned a unique SEQ ID, making each RTS sequence distinguishable. This segmentation allows the PPD to identify and accept at least one RTS sequence among multiple simultaneous requests, thereby improving both the efficiency and reliability of right-to-speak determination.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If the PPD receives multiple identical RTS sequences, then it can process the requests, but all requests are refused leading to repeated resending and time waste

Engineering Contradiction:
Improvesimplicity of RTS sequence processingVSAvoidtime for resending RTS sequences
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent implements preliminary action by pre-configuring unique SEQ IDs for each SPD before they attempt to send RTS sequences. This pre-assignment of distinct identifiers ensures that when multiple SPDs send RTS sequences simultaneously, the PPD can immediately distinguish between them based on their unique SEQ IDs without requiring complex processing. This preliminary differentiation prevents the rejection of all requests and eliminates the need for repeated resending, thereby reducing time loss while maintaining simple processing operations.

Inventive Principle:
Principle #10Preliminary action

3Device complexity

If all SPDs use the same RTS sequence content, then the protocol is simple to implement, but the determination of right to speak becomes inefficient when multiple SPDs request simultaneously

Engineering Contradiction:
Improvecomplexity of RTS sequence protocolVSAvoidefficiency of right to speak determination
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The patent applies local quality by making only the SEQ ID portion of the RTS sequence unique for each SPD, while keeping the rest of the RTS sequence content identical and simple. This localized differentiation maintains the overall simplicity of the RTS protocol structure while introducing just enough variability in the SEQ ID field to enable efficient identification and selection of one SPD among multiple simultaneous requesters, thereby improving productivity without significantly increasing device complexity.

Inventive Principle:
Principle #3Local quality

AI summary

Embodiments of the present invention disclose a system, apparatuses and methods for determining the right to speak. In the embodiments, each Secondary Protective Device (SPD) selects a Request to Send (RTS) sequence from a preconfigured RTS sequence set and sends the selected RTS sequence to a Primary Protective Device (PPD); the PPD chooses one RTS sequence from the RTS sequence sent by the SPDs and sends the chosen RTS sequence to all the SPDs; and then each SPD determines whether the right to speak is obtained according to the RTS sequence from the PPD. The system, apparatuses and methods provided by the embodiments of the present invention ensure that the RTS sequences sent to the PPD by the SPDs are almost always different; therefore, the efficiency of determining the right to speak is greatly improved and the satisfaction of users is improved effectively.
