Solution Overview

Problem

High-powered undesired RF radiation at cell sites causes interference and noise, leading to poor performance indicators such as low sector and individual UE throughput, which existing technologies fail to effectively mitigate.

Innovation Solution

Employing sector power ratio (SPR) information to dynamically manage the number of users assigned to a wireless communication protocol by re-assigning users from a protocol with high SPR and poor performance indicators to another protocol, thereby reducing interference and improving performance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the number of users assigned to a wireless communication protocol is increased to improve network capacity, then productivity increases, but interference and noise increase causing performance indicators to deteriorate

Engineering Contradiction:

Improvenetwork capacityVSAvoidinterference and noise

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent implements dynamic user assignment that adjusts the number of users assigned to each wireless communication protocol based on real-time sector power ratio measurements and performance indicator monitoring. The system continuously evaluates SPR values and KPI thresholds, modifying user assignment decisions dynamically rather than using static allocation, thereby adapting network capacity and interference management to changing conditions.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system employs feedback mechanisms by monitoring performance indicators (throughput, data usage, connection drops) and sector power ratio values, then using this feedback to adjust user assignment decisions. When KPIs fall below thresholds or SPR exceeds thresholds, the system responds by reassigning users between protocols, creating a closed-loop control system that continuously optimizes the balance between network capacity and interference levels.

Inventive Principle:

Principle #23Feedback

2Object-generated harmful factors

If users are re-assigned from a protocol with high SPR to another protocol to reduce interference, then object-generated harmful factors decrease, but device complexity increases due to dynamic management requirements

Engineering Contradiction:

Improveundesired RF radiationVSAvoiddynamic user management system

Core Design Contradiction:

Object-generated harmful factorsVSDevice complexity

Solution Approach 1:

The patent introduces a network entity acting as an intermediary that centralizes the complex task of monitoring sector power ratios and managing user assignments across multiple wireless communication protocols. This intermediary entity collects SPR measurements, evaluates performance indicators, and executes user reassignment decisions, thereby isolating the complexity within a dedicated management system rather than distributing it across all network components.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system manages complexity by monitoring and responding to changes in specific parameters (sector power ratio thresholds and performance indicator thresholds). Rather than managing all possible network variables, the invention focuses on key parameters that directly indicate interference conditions and protocol performance, using threshold-based decision rules to simplify the complexity of dynamic user management.

Inventive Principle:

Principle #35Parameter changes

3Productivity

If the number of users on a protocol is capped to improve performance indicators, then sector throughput improves, but loss of information occurs as users may be disconnected from optimal protocols

Engineering Contradiction:

Improvesector throughputVSAvoiduser connection continuity

Core Design Contradiction:

ProductivityVSLoss of information

Solution Approach 1:

The patent converts the potentially harmful effect of user disconnection into a beneficial outcome by systematically reassigning users between protocols based on measured performance and interference conditions. Rather than treating protocol switching as a disruption, the system frames it as a corrective action that moves users to more appropriate protocols, thereby converting the 'harm' of connection changes into the 'benefit' of improved overall network performance and reduced interference.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

AI summary

Systems, methods, and computer-readable media herein dynamically assign user devices to communicate to cell sites and antenna arrays using either a first wireless communication protocol or a second wireless communication protocol. The sector power ratio (SPR) for a wireless communication protocol is monitored to determine if a key performance indicator (KPI) should be monitored. Once the SPR exceeds a pre-determined threshold, the KPI is monitored to determine to what degree, if any, the KPI has exceeded a threshold value. An upper limit to the number of user devices allowed to communicate to the cell cite using the first wireless communication protocol is then modified at least in part based on the SPR and the KPI values. User devices are then re-assigned from the first to the second wireless communication protocol based on the modified upper limit of user devices allowed to use the first wireless communication protocol.
