Wireless Signalling Compression via Dictionary-Based Indexing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Signalling congestion in wireless networks occurs due to increased data traffic and device density, leading to network breakdowns, particularly when many devices access the network synchronously, and existing solutions either block low-priority requests or introduce additional delays through batch handling.
Innovation Solution
A method that builds a dictionary of collected signalling messages to compress and reconstruct messages, reducing redundancy and bandwidth usage without increasing network complexity, allowing for lossless and timely communication by using the dictionary to replace redundant sections with indices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If conventional approaches block or drop non-urgent signalling requests to reduce congestion, then high priority requests can be transmitted quickly, but low priority requests experience long delays or are completely neglected
Solution Approach 1:
The patent merges multiple signalling requests into a single batch transmission. Instead of handling each request individually (which causes delays for low priority requests), the system collects multiple requests and transmits them together in one batch, reducing overall transmission time and eliminating the need to block or drop low priority requests.
Solution Approach 2:
The system performs preliminary actions by collecting and buffering signalling requests before transmission. Rather than immediately transmitting each request as it arrives (which causes congestion), the system preliminarily accumulates requests in a buffer and then transmits them in optimized batches, improving both speed and time efficiency.
2Quantity of substance
If batch signalling handling is used to reduce congestion, then signalling overhead is reduced, but additional delay is introduced by aggregation
Solution Approach 1:
The patent applies partial batch handling rather than complete aggregation. Instead of waiting for a full batch to accumulate before transmitting (which introduces excessive delay), the system transmits batches when a threshold is reached or at optimized intervals, achieving partial compression of signalling overhead while minimizing aggregation delay through selective batch transmission.
3Productivity
If device density increases to meet data traffic growth, then network capacity is improved, but signalling congestion increases leading to network breakdown
Solution Approach 1:
The patent merges signalling requests from multiple devices into batch transmissions. As device density increases and more devices generate signalling requests, the batch handling mechanism combines these requests efficiently, preventing the linear increase in signalling overhead that would otherwise cause network congestion and breakdown, thereby maintaining network stability despite increased capacity demands.

AI summary
Method and devices for mitigating signalling congestion in a wireless network, comprising building up (S1) a dictionary of collected signalling messages, the signalling messages being used as reference signalling messages and being transmitted on a signalling channel between at least one base station and mobile devices, the mobile devices having a concrete relationship like the same proximate area or device capability or service purposes, and compressing (S2) signalling messages being transmitted on the signalling channel between the base station and the mobile devices, based on the dictionary of the collected reference signalling messages.
