Solution Overview

Problem

Current handover mechanisms in communication networks do not adequately account for user preferences and application requirements, leading to suboptimal performance and increased costs due to reliance on generalized rules rather than personalized settings.

Innovation Solution

A rules engine that allows users to create and enforce customized handover policies based on their experiences and application needs, integrating user-defined rules with network-based and device-based handover mechanisms to optimize connectivity and resource utilization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If generalized handover rules are used, then device complexity is reduced and ease of operation is improved, but adaptability to user preferences and application requirements deteriorates

Engineering Contradiction:
Improveease of handover managementVSAvoidadaptability to user preferences
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The handover rule set is segmented into multiple components: generalized handover rules that provide baseline operation, user-defined rules that capture personal preferences, and application-defined rules that address specific application requirements. This segmentation allows each layer to operate independently while collectively providing comprehensive handover management that is both easy to operate and highly adaptable.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The handover mechanism is designed with multi-functionality to serve multiple purposes: it handles standard network-based handovers, device-based handovers, user-preference-based handovers, and application-requirement-based handovers within a unified framework. This universal approach maintains ease of operation while achieving broad adaptability across different scenarios.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If user-defined handover rules are implemented, then adaptability to user preferences and application requirements is improved, but device complexity increases

Engineering Contradiction:
Improveadaptability to user preferencesVSAvoidcomplexity of handover management
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system adds a new dimension to handover management by introducing a rule-priority hierarchy. Instead of managing complexity through additional components, the solution organizes rules across dimensional layers: network-based rules, device-based rules, user-defined rules, and application-defined rules. Each layer operates with defined priority relationships, allowing complex adaptability to be managed through structured organization rather than increased complexity.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Productivity

If multiple handover rule types are integrated, then adaptability and performance optimization are improved, but conflict between rules may increase

Engineering Contradiction:
Improvenetwork performanceVSAvoidrule conflict consistency
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system performs preliminary conflict detection and resolution by establishing a defined priority hierarchy among different rule types before handover decisions are made. Network-based rules, device-based rules, user-defined rules, and application-defined rules are pre-ordered with clear precedence relationships. This preliminary structuring prevents rule conflicts from causing reliability issues during actual handover operations, allowing multiple rule types to work together to optimize network performance.

Inventive Principle:
Principle #10Preliminary action

AI summary

The claimed subject matter provides a system and/or a method that facilitates optimizing handover in connection with an access network. An access network can include at least one device exchanges data therewith, wherein the device communicates with at least one access station within the access network to exchange data. A rules engine can create a user-defined rule based upon at least one of a resource requirement for a device application or a user input related to a quality of service (QoS) experience with the device. The rules engine can enforce the user-defined rule to employ handover related to the device and at least one of an access station within the access network or a disparate access network.
