Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Traditional wireless communication networks face inefficiencies in service handovers due to the increasing complexity introduced by numerous smaller cells, such as picocells and femtocells, which are not adequately detected by user equipment, leading to network congestion and poor Quality of Service (QOS) and Quality of Experience (QOE).

Innovation Solution

A networked computing system that utilizes a radio communications controller to receive feedback from transceiver devices to determine and assign alternate service provider resources for user equipment, based on measured characteristics of ancillary communications, thereby reducing the burden on user equipment and shifting service handover tasks to distributed network resources.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Difficulty of detecting and measuring

If user equipment scans for available cells to detect smaller cells, then cell detection capability is improved, but device complexity and power consumption increase significantly

Engineering Contradiction:

Improvecell detection capabilityVSAvoiduser equipment complexity

Core Design Contradiction:

Difficulty of detecting and measuringVSDevice complexity

Solution Approach 1:

The patent introduces network infrastructure elements (base stations, controllers) as intermediaries that perform cell detection and measurement on behalf of user equipment. These network elements scan for smaller cells and collect feedback information, then provide this information to user equipment, eliminating the need for user equipment to perform complex scanning operations themselves

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The network infrastructure performs self-service by autonomously detecting smaller cells, measuring their characteristics, and managing handover decisions without requiring user equipment intervention. The system uses network-based measurement and feedback mechanisms where base stations independently identify available cells and coordinate service transitions

Inventive Principle:

Principle #25Self-service

2Reliability

If user equipment performs comprehensive cell scanning, then service handover reliability is improved, but loss of time and power consumption increase

Engineering Contradiction:

Improveservice handover reliabilityVSAvoidhandover time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The network infrastructure performs preliminary cell detection and measurement actions in advance, maintaining updated information about available smaller cells before handover is needed. Base stations continuously scan and report cell conditions to controllers, so when handover is required, the decision can be made immediately using pre-collected data

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system implements network-based feedback mechanisms where base stations provide continuous information about cell availability and quality to controllers. This feedback loop enables the network to proactively identify suitable target cells and prepare handover parameters, reducing the time required when actual handover execution is needed

Inventive Principle:

Principle #23Feedback

3Productivity

If distributed smaller cells are added to reduce network congestion, then network capacity is improved, but device complexity for detecting these cells increases

Engineering Contradiction:

Improvenetwork capacityVSAvoiddetection system complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent uses network infrastructure as an intermediary layer between user equipment and the distributed smaller cells. Base stations and controllers manage the complexity of detecting and coordinating multiple smaller cells, presenting a simplified interface to user equipment while handling the sophisticated cell management tasks in the network domain

Inventive Principle:

Principle #24Intermediary (Mediator)

4Speed

If user equipment autonomously determines service assignments, then responsiveness is improved, but measurement precision and reliability decrease due to limited user equipment capabilities

Engineering Contradiction:

Improveservice assignment responsivenessVSAvoidcell measurement precision

Core Design Contradiction:

SpeedVSMeasurement precision

Solution Approach 1:

The network controller acts as an intermediary that performs precise measurements and evaluations of available cells, then uses this accurate information to make service assignment decisions. The controller receives measurement data from multiple base stations, evaluates cell quality with high precision, and determines optimal service assignments based on network-wide information rather than limited user equipment measurements

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A networked computing system for assigning regional wireless communications based on ancillary device feedback. The network computing system includes a radio communications controller, one or more transceiver device(s), user equipment, and data communications network facilitating data communications amongst the wireless communications devices of the networked computing system. The radio communications controller may be configured to receive a feedback communication from a network transceiver device capable of detecting ancillary wireless communications, and then determine whether an alternate service provider resource exists for providing wireless data communications service to the user equipment within the data communications network, based on the received feedback communication.
