Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile communication devices engaging in impermissible behaviors, such as repeated invalid log-in attempts or transmitting malformed packets, can drain battery life and exhaust radio link capacity, impacting device performance and user access to services.
Innovation Solution
A network security system detects and responds to impermissible behaviors by restricting access and transmitting instructions to the device, allowing network security systems to handle detection, thereby reducing the impact on the device's performance and power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a client application is installed on the mobile communication device to detect impermissible behaviors, then impermissible behaviors can be detected, but memory consumption and processor usage increase, negatively impacting device performance
Solution Approach 1:
The patent extracts the complex detection functionality from the mobile device and relocates it to the network device. The mobile device only needs to transmit usage data and receive control signals, while the network device performs the computationally intensive analysis of impermissible behaviors. This extraction resolves the contradiction by maintaining detection capability while eliminating the memory and processor burden from the mobile device.
Solution Approach 2:
The patent introduces a network device as an intermediary between the mobile device and the detection system. The network device acts as a mediator that receives usage data from multiple mobile devices, performs centralized analysis to detect impermissible behaviors, and sends control signals back to the mobile devices. This intermediary approach allows sophisticated detection without requiring complex client applications on each mobile device.
2Reliability
If a client application is installed on the mobile communication device to detect impermissible behaviors, then impermissible behaviors can be detected, but the application consumes significant memory and processing power, also negatively impacting device performance
Solution Approach 1:
The patent extracts the energy-intensive detection processing from the mobile device's battery-powered processor and relocates it to the network device's infrastructure. The mobile device's client application becomes a thin client that only transmits data and receives commands, eliminating the need for continuous local processing and significantly reducing battery consumption while maintaining detection effectiveness.
Solution Approach 2:
The network device performs self-service by autonomously analyzing usage data from multiple mobile devices to detect impermissible behaviors. This centralized self-service approach eliminates the need for each mobile device to independently perform complex detection algorithms, thereby reducing the energy burden on individual mobile devices while maintaining comprehensive security monitoring.
3Reliability
If the mobile communication device handles detection locally, then detection can be performed, but the device's battery is drained and radio link capacity is exhausted, impacting intended usage
Solution Approach 1:
The patent extracts the resource-intensive detection operations from the mobile device and performs them on the network device. This extraction prevents the mobile device's battery and radio link from being exhausted by detection activities, preserving the device's productivity for its intended purposes such as calls, messaging, and application usage while maintaining effective security monitoring.

AI summary
A device detects an impermissible behavior by a user device. The device further identifies a rule associated with the impermissible behavior and executes a response to the impermissible behavior based on the rule. The response restricts access of the user device to a service provided by or via a network device. The device also transmits, to the user device, a message that specifies the response. The device also verifies a termination of a cause of the impermissible behavior and restores the access of the user device to the service.
