Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless networks face challenges in accurately diagnosing performance issues due to compromised data integrity and availability, especially underperforming conditions, which can lead to unsatisfactory network performance and inefficient resource utilization.
Innovation Solution
The implementation of an out-of-band communication channel that exploits spectral resources outside the primary wireless network's band, allowing for resilient performance diagnosis of wireless equipment and networks by using a service platform to collect and analyze data through a mobility control node, thereby distinguishing between network-based and equipment-based faults.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If in-band communication is used for performance diagnosis, then data collection is straightforward, but data integrity and availability are compromised under performing conditions
Solution Approach 1:
The patent introduces an out-of-band communication channel as an intermediary path for data collection. This separate communication path allows performance diagnosis data to be transmitted independently from the primary wireless network, ensuring data integrity even when the network is underperforming. The out-of-band channel acts as a mediator that bypasses network issues while maintaining straightforward data collection capabilities.
2Loss of information
If conventional in-band monitoring is used, then network performance assessment is integrated, but data availability is hindered in underperforming conditions
Solution Approach 1:
The patent adds a new dimension to data collection by implementing an out-of-band communication channel that operates independently from the primary wireless network band. This dimensional separation ensures that performance diagnosis data can be collected and transmitted through an alternative path when the primary network is underperforming, thereby maintaining data availability without complicating the operational simplicity of data collection.
3Reliability
If out-of-band communication is implemented, then diagnosis resilience is enhanced, but communication infrastructure complexity increases
Solution Approach 1:
The patent extracts the performance diagnosis communication function from the primary wireless network infrastructure and places it in a separate out-of-band channel. This extraction enhances diagnosis resilience by isolating the monitoring function from network performance issues, while the separation actually simplifies the overall communication infrastructure by dedicating specific resources to monitoring without interfering with primary network operations.

AI summary
Performance issues of wireless equipment (WE) or a wireless network are diagnosed through an alternative communication channel enabled by an alternative wireless network available to the WE. A service platform (SP) probes performance condition of the WE through a mobility control node (MCN) and, in response to a fault condition, collects data related to operation of the WE. Based at least on part of the data, the SP diagnoses the fault condition and related performance issue(s). To probe performance, the SP requests the MCN to collect data related to performance metric(s) of the WE. The alternative communication channel is established, and such data is collected therefrom, in response to low-grade connectivity amongst the MCN and the WE. The SP notifies the WE of at least the fault condition through the MCN or, in case of network fault condition, via the alternative communication channel.
