Solution Overview

Problem

Current communication networks face challenges in managing bandwidth and Quality of Service (QoS) effectively, especially with the increasing demand for multiple services and applications over shared broadband connections, requiring customized content delivery that meets user and provider preferences.

Innovation Solution

The implementation of a system that allows for the modification of bandwidth and QoS in a Regional/Access Network (RAN) through Application Programming Interface (API) calls and Operational Support System (OSS) interactions, enabling enterprises, Network Service Providers (NSPs), and Application Service Providers (ASPs) to query and modify resource allocations, prioritize traffic, and manage bandwidth and QoS across multiple services and applications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple services and applications are delivered over a single network connection, then service diversity and user preferences are improved, but bandwidth management and QoS allocation become more complex

Engineering Contradiction:

Improveservice diversityVSAvoidbandwidth management complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces an intermediary system that mediates between multiple services/applications and the network connection. This intermediary manages bandwidth allocation and QoS parameters centrally, allowing diverse services to coexist on a single connection without each service independently managing resources, thus reducing overall management complexity while maintaining service diversity

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent creates a universal bandwidth management system that handles multiple services and applications through a single unified interface and control mechanism. This multi-functional system can allocate bandwidth and manage QoS across different service types (voice, video, data, gaming) simultaneously, eliminating the need for separate management systems for each service

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If QoS and bandwidth allocation are customized for multiple services, then user experience and service performance are improved, but network control and resource allocation complexity increase

Engineering Contradiction:

Improveservice performanceVSAvoidnetwork control complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent utilizes parameter changes by dynamically adjusting QoS parameters (bandwidth allocation, priority levels, latency thresholds) based on service requirements and network conditions. The system modifies these parameters in real-time through automated control mechanisms, ensuring optimal service performance without requiring complex manual network configuration for each service

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent implements dynamic bandwidth allocation and QoS management where resource allocation automatically adapts to changing service demands and network conditions. The system continuously monitors service performance and adjusts bandwidth allocation dynamically, replacing static allocation methods with adaptive control that reduces network management complexity while maintaining high service reliability

Inventive Principle:

Principle #15Dynamics

3Adaptability or versatility

If real-time bandwidth and QoS modifications are enabled, then network flexibility and responsiveness are improved, but system overhead and processing requirements increase

Engineering Contradiction:

Improvenetwork flexibilityVSAvoidprocessing overhead

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The patent applies preliminary action by pre-configuring QoS parameters and bandwidth allocation policies for different service types before actual service deployment. The system establishes default QoS profiles and allocation rules in advance, allowing real-time modifications to occur based on pre-established frameworks rather than requiring complex real-time decision-making for every parameter change, thus reducing processing overhead while maintaining network flexibility

Inventive Principle:

Principle #10Preliminary action

AI summary

Bandwidth and/or Quality of Service (QoS) may be modified in a Regional/Access Network (RAN) that includes a core network, the RAN facilitating differentiated end-to-end data transport between an enterprise, a Network Service Provider (NSP), and/or an Application Service Provider (ASP) and a customer Premises Network (CPN). Application Programming Interface (API) calls are used at the enterprise, NSP, and/or the ASP to communicate with the RAN to query a resource allocation in the core network that is assigned to the enterprise, NSP, and/or the ASP. API calls are also used at the enterprise, NSP, and/or the ASP to communicate with the RAN to modify the bandwidth and/or the QoS of the resource allocation in the core network that is assigned to the enterprise, NSP, and/or the ASP.
