Solution Overview

Problem

Wireless networks face performance degradation and service outages due to aggressive behavior from mobile devices, such as repetitive connection attempts, which consume excessive resources and cause network overload, leading to challenging restoration tasks.

Innovation Solution

A cloud-based control center with software agents strategically placed in Subscriber Identity Modules (SIM) or Signal Transfer Points (STP) monitors and controls aggressive device behavior by comparing signature patterns with current data traffic, implementing solutions such as over-the-air instructions to modify device behavior or network elements to mitigate aggressive actions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If wireless networks are designed with pre-determined capacity and performance planning, then network resources are optimized for expected device behavior, but the network becomes vulnerable to aggressive device behavior that consumes excessive resources and causes service outages

Engineering Contradiction:
Improvenetwork resource utilization efficiencyVSAvoidnetwork service stability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system performs preliminary characterization of device behavior patterns during normal operation, building a baseline profile of expected signaling activity and resource consumption. This preliminary action enables the network to quickly identify deviations caused by aggressive devices without requiring reactive resource allocation, thus maintaining both efficiency and stability

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

A software agent acts as an intermediary between the mobile device and the network core, monitoring device behavior and intercepting aggressive signaling attempts. The agent characterizes behavior patterns and communicates with the control center, preventing excessive resource consumption while allowing legitimate network operations to proceed normally

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of energy

If the network denies service requests to aggressive devices, then network resource consumption is reduced, but the aggressive device continues to retry connections consuming power and creating signaling load

Engineering Contradiction:
Improvenetwork resource consumptionVSAvoidsignaling load from retry attempts
Core Design Contradiction:
Loss of energyVSObject-generated harmful factors

Solution Approach 1:

The system implements feedback by continuously monitoring device behavior patterns and adjusting network responses dynamically. When aggressive behavior is detected through characterized patterns of repeated connection attempts, the network applies escalating countermeasures including temporary blocking and coordination with other network nodes, creating a feedback loop that reduces both energy consumption and signaling load from persistent retries

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system applies preliminary anti-action by proactively identifying aggressive devices through behavior characterization and implementing preventive measures before excessive resource consumption occurs. The control center coordinates with multiple network nodes to establish blocking rules and throttling policies in advance, preventing the harmful retry cycle from fully developing

Inventive Principle:
Principle #9Preliminary anti-action

3Difficulty of detecting and measuring

If software agents are deployed in SIM cards or STP nodes to monitor device behavior, then aggressive behavior detection capability is enhanced, but system complexity and deployment difficulty increase

Engineering Contradiction:
Improveaggressive behavior detection accuracyVSAvoidsystem architecture complexity
Core Design Contradiction:
Difficulty of detecting and measuringVSDevice complexity

Solution Approach 1:

The software agent is designed as a universal, multi-functional component that can be deployed in multiple locations (SIM cards, STP nodes, network elements) to perform behavior characterization, monitoring, and coordination functions. This universal design reduces overall system complexity by consolidating detection capabilities into a standardized agent architecture rather than requiring custom solutions at each deployment point

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The software agent operates autonomously, self-configuring and self-managing the behavior monitoring and characterization processes. The agent collects data, analyzes patterns, and communicates findings to the control center without requiring manual intervention, reducing operational complexity while maintaining high detection accuracy through automated behavior analysis

Inventive Principle:
Principle #25Self-service

4Reliability

If the control center coordinates with multiple network nodes to block aggressive devices, then service outage prevention capability is improved, but the complexity of network coordination and restoration tasks increases

Engineering Contradiction:
Improveservice outage preventionVSAvoidnetwork restoration complexity
Core Design Contradiction:
ReliabilityVSEase of repair

Solution Approach 1:

The system replaces manual network restoration procedures with automated electronic coordination between the control center and network nodes. The control center electronically communicates blocking and unblocking commands to multiple nodes simultaneously, replacing complex manual restoration tasks with automated software-based coordination that reduces both prevention and restoration complexity

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
