Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Communication networks face significant traffic surges due to increased registration requests from devices, leading to network overload and failure in processing control messages efficiently, resulting in potential access denial.

Innovation Solution

Implementing a system that selectively discards new registration attempts based on network entity overload levels, using an overload table with corresponding discard percentages to manage traffic flow and maintain optimal processing rates, while ensuring initiated registration processes are completed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the network controller processes all registration requests during traffic surges, then network access availability is improved, but network overload increases and processing efficiency deteriorates

Engineering Contradiction:

Improvenetwork access availabilityVSAvoidprocessing efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent extracts and discards a portion of new registration requests during traffic surges based on overload levels. By removing excessive registration requests from the processing queue, the system prevents network overload while maintaining processing efficiency for remaining requests and ongoing registration processes.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent dynamically changes the processing parameters by adjusting the number of concurrent registration processes based on measured overload levels. When overload exceeds thresholds, the system reduces the number of processed requests, thereby maintaining optimal processing efficiency while preventing system collapse.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If the network controller accepts all new registration requests, then network access availability is improved, but network traffic congestion worsens

Engineering Contradiction:

Improvenetwork access availabilityVSAvoidnetwork traffic volume

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The patent extracts and discards a controlled portion of new registration requests during traffic surges. By removing approximately 50-70% of excessive registration requests when overload exceeds thresholds, the system reduces network traffic volume while maintaining sufficient access availability for legitimate users.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent applies partial action by selectively processing only a portion of registration requests based on overload conditions. Instead of processing all requests or none, the system processes an optimal subset that maintains network stability while providing access services.

Inventive Principle:

Principle #16Partial or excessive action

3Productivity

If the network controller discards new registration requests during surges, then network traffic congestion is reduced, but network access availability deteriorates

Engineering Contradiction:

Improveprocessing efficiencyVSAvoidnetwork access availability

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent implements dynamic discard ratios that adjust based on measured overload levels. The discard percentage is not fixed but varies dynamically with network conditions, allowing the system to maintain optimal processing efficiency while adapting access availability to current traffic conditions.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the processing parameters by adjusting the number of concurrent registration processes and discard ratios based on overload thresholds. This parameter adaptation allows the system to balance processing efficiency and access availability according to real-time network conditions.

Inventive Principle:

Principle #35Parameter changes

4Reliability

If the network controller processes all control messages, then network access availability is improved, but network entity overload increases

Engineering Contradiction:

Improvenetwork access availabilityVSAvoidnetwork entity overload

Core Design Contradiction:

ReliabilityVSStress or pressure

Solution Approach 1:

The patent extracts and removes excessive control messages (registration requests) during traffic surges. By discarding a controlled portion of new registration requests when overload exceeds thresholds, the system reduces stress on network entities while maintaining sufficient access availability.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent dynamically adjusts the processing capacity and discard ratios based on real-time overload measurements. This dynamic adaptation allows the system to maintain network entity stability while providing access services under varying load conditions.

Inventive Principle:

Principle #15Dynamics

AI summary

System and method for traffic surge control. A control message may be received for registering or managing a device in a network. A measure of a number of current control messages already being processed in the network may be retrieved. A condition may be retrieved, from among a plurality of conditions, that corresponds to the retrieved measure of current control messages, each condition defining different rules for discarding a control message of the same type and corresponding to one of a plurality of measures of current control messages. Based on whether or not the retrieved condition is met, the control message may be processed to register or manage the device or discarded.
