Solution Overview

Problem

Existing radio communication protection methods, such as Hot Stand-By and redundancy-based solutions, fail to differentiate protection levels according to the type of information transmitted, leading to inefficient use of network resources and potential errors during switching, especially in packet-based transmissions where different packets require varying levels of quality of service.

Innovation Solution

The solution involves dividing payload information into smaller data portions, grouping them into packets based on priority criteria, and labeling these packets for transmission over suitable radio channels, ensuring that higher-priority data is protected and transmitted accordingly, using a packet processor and transmitter to manage and allocate packets based on their priority levels.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If Hot Stand-By configuration is used for hardware failure protection, then system reliability is improved, but switching errors may occur and network resources are inefficiently used

Engineering Contradiction:
Improveprotection against hardware failureVSAvoidswitching errors
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The payload is divided into multiple data portions with different priority levels, allowing selective protection and transmission. High-priority portions receive enhanced protection measures while low-priority portions use standard protection, resolving the contradiction by segmenting the protection approach rather than applying uniform protection.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different protection qualities are applied to different data portions based on their priority. Critical data portions receive higher levels of protection (redundancy, error correction) while non-critical portions receive minimal protection, optimizing resource usage and avoiding unnecessary switching operations for non-critical data.

Inventive Principle:
Principle #3Local quality

2Reliability

If redundancy-based protection is applied to all channels, then system reliability is improved, but network resources are inefficiently consumed

Engineering Contradiction:
Improveprotection levelVSAvoidnetwork resources
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The data stream is segmented into priority-based portions, allowing the system to apply redundancy only where necessary. This segmentation enables differential protection strategies that match resource allocation to actual need, improving efficiency while maintaining reliability for critical data.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The protection level parameter is dynamically adjusted based on data priority and channel conditions. High-priority data receives higher protection parameters (more redundancy, stronger error correction) while low-priority data receives reduced protection, optimizing the balance between reliability and resource consumption.

Inventive Principle:
Principle #35Parameter changes

3Device complexity

If uniform protection is applied to all packets, then implementation simplicity is maintained, but quality of service requirements cannot be met

Engineering Contradiction:

Core Design Contradiction:

Solution Approach 1:

Priority classification is performed in advance during packet formation, labeling data portions with priority information before transmission. This preliminary action enables downstream components to apply appropriate protection levels without complex real-time decision-making, maintaining implementation simplicity while achieving differentiated quality of service.

AI summary

System and method for improving the protecting radio channels in transmission, according to which the payload information of the signal to be transmitted is divided into a plurality of data portions of smaller size which are then grouped into packets and the packets are labeled based on a criterion from among a plurality of criteria, said criterion being indicative of a level of priority associated to said packets. The packets are subsequently radio transmitted in accordance with their level of priority indicated by their associated label.
