RTS Sequence Determination Using Unique SEQ IDs
Find Innovative SolutionsGenerate Solutions
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 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
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.
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
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.
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
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.

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.
