Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing packet capture tools struggle to diagnose wireless communication issues when user equipment transitions from one access point to another, as they fail to adapt to the new frequency used by the second access point, leading to incomplete packet capture.

Innovation Solution

Implementing dynamic channel adaptation in a computing device that monitors and adjusts the wireless transceiver to capture packets on both the initial and subsequent frequencies used by the user equipment as it switches between access points, ensuring complete packet capture.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the packet capture tool uses a fixed wireless frequency, then the device complexity is reduced, but the packet capture becomes incomplete when UE switches to a different frequency

Engineering Contradiction:

Improvepacket capture completenessVSAvoidfrequency monitoring and adaptation mechanism

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic channel adaptation by continuously monitoring the wireless frequency used by the UE and automatically adjusting the packet capture tool's frequency setting. When the UE switches from one frequency to another, the system detects this change and updates the capture frequency accordingly, ensuring complete packet capture across frequency transitions.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system employs feedback mechanisms by monitoring the frequency information transmitted by the UE and using this information to adjust the packet capture settings. The feedback loop ensures that the capture tool remains synchronized with the UE's current frequency, maintaining capture completeness without requiring manual intervention.

Inventive Principle:

Principle #23Feedback

2Reliability

If the packet capture tool monitors frequency changes dynamically, then the packet capture completeness improves, but the use of energy increases

Engineering Contradiction:

Improvepacket capture completenessVSAvoidenergy consumption of frequency monitoring

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent implements periodic frequency monitoring rather than continuous monitoring, checking the frequency at specific intervals or triggered by detected events. This periodic approach maintains capture completeness while significantly reducing energy consumption compared to continuous monitoring, as the system only activates frequency checks when necessary.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The system uses the frequency information that is already being transmitted by the UE for its own communication purposes. By leveraging the existing frequency signaling in the wireless communication protocol, the packet capture tool can monitor frequency changes without requiring separate dedicated monitoring mechanisms, thus minimizing additional energy consumption.

Inventive Principle:

Principle #25Self-service

AI summary

A computing device that includes a wireless transceiver operable to receive communications on a designated wireless frequency obtains a first wireless frequency identifier that corresponds to a first wireless frequency being used by a user equipment (UE) to wirelessly communicate with a first wireless access point (AP). The computing device sends instructions to the wireless transceiver to set the designated wireless frequency to the first wireless frequency. The computing device determines that the UE switched from using the first wireless frequency to using a second wireless frequency to communicate with a second AP. The computing device, in response to determining that the UE switched from using the first wireless frequency to using the second wireless frequency, sends instructions to the wireless transceiver to set the designated wireless frequency to the second wireless frequency.
