Solution Overview

Problem

Wireless providers face challenges in providing optimal Quality of Service (QoS) when using shared frequency carriers, as subscribers cannot distinguish between licensed and shared carriers, leading to unfair attribution of poor performance to the provider.

Innovation Solution

Implementing a system that selectively enables or disables shared access cells based on Key Performance Indicators (KPIs), allowing wireless providers to manage connections on a per-application basis and compare KPIs with licensed cells to ensure better user experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If shared frequency carriers are used to expand network coverage, then the area of service is increased, but the quality of service deteriorates due to performance issues that cannot be distinguished from licensed carriers

Engineering Contradiction:

Improvenetwork coverage areaVSAvoidquality of service

Core Design Contradiction:

Area of stationary objectVSReliability

Solution Approach 1:

The patent segments the carrier types into distinct categories (licensed vs. shared) and implements separate management mechanisms for each. The network device identifies and differentiates between carrier types, allowing selective application of quality control measures to shared carriers while maintaining standard operations for licensed carriers.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent changes the operational parameters of shared carriers dynamically by adjusting quality thresholds and enabling/disabling carriers based on monitored performance metrics. This allows the system to adapt shared carrier usage to maintain quality standards while maximizing coverage benefits.

Inventive Principle:

Principle #35Parameter changes

2Productivity

If shared access cells are continuously enabled to maximize resource utilization, then network capacity is improved, but user experience deteriorates when performance thresholds are not met

Engineering Contradiction:

Improvenetwork capacityVSAvoiduser experience

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent implements dynamic management of shared access cells through continuous monitoring of quality metrics and real-time adjustments to cell status. The system transitions cells between enabled and disabled states based on whether they meet quality thresholds, creating a flexible resource allocation mechanism that adapts to changing conditions.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent establishes a feedback loop where the network device monitors quality metrics of shared access cells and uses this information to make informed decisions about cell enablement. The continuous quality assessment feeds back into resource management decisions, ensuring that capacity optimization does not compromise user experience.

Inventive Principle:

Principle #23Feedback

3Reliability

If quality thresholds for shared carriers are strictly enforced, then quality of service is improved, but network coverage is reduced due to disabling of shared access cells

Engineering Contradiction:

Improvequality of serviceVSAvoidnetwork coverage

Core Design Contradiction:

ReliabilityVSArea of stationary object

Solution Approach 1:

The patent applies quality requirements locally and selectively to shared carriers rather than uniformly across all carriers. By identifying specific shared carriers that fail to meet quality thresholds and disabling only those particular cells, the system maintains quality standards where needed while preserving coverage through other acceptable shared carriers.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent implements a mechanism where shared access cells are temporarily discarded (disabled) when they fail quality thresholds but can be recovered (re-enabled) when they improve. This allows the system to maintain quality standards while preserving the potential coverage contribution of shared carriers that may experience temporary performance degradation.

Inventive Principle:

Principle #34Discarding and recovering

AI summary

Techniques described herein may allow for the selective enabling and/or disabling of shared access points (“SAPs”). The selective enabling and/or disabling may occur based on the analysis of key performance indicators (“KPIs”) associated with the SAPs. The selective enabling and/or disabling may cause the SAPs to cease (or continue) broadcasting their availability for User Equipment (“UEs”) of a particular wireless provider, decline (or accept) bearer requests for UEs of the particular wireless provider, or terminate existing connections with UEs of the particular wireless provider. The selective enabling and/or disabling may be performed for certain applications or Quality of Service (“QoS”) levels. The selective enabling and/or disabling may be performed proactively (e.g., without necessarily determining that the performance for a given SAP has not met a threshold performance), based on historical trends.
