Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current Next Generation Network (NGN) Resource and Admission Control Systems (RACS) drafts lack detailed solutions for resource reservation in customer request mode, particularly in terms of interface requirements and workflows, despite supporting multiple resource reservation modes.

Innovation Solution

A method for resource reservation in customer request mode is introduced, where a Resource Mediation Policy Decision Function (RM-PDF) receives resource requests from customer premise equipment (CPE) through a Border Gateway Function (BGF), determining compliance with customer configuration and network policy rules, and sends admission installation instructions for resource reservation when resources are available, enabling direct resource initiation, modification, and release by CPE through dedicated signaling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If RACS framework definitions are kept fixed and simple, then device complexity is reduced, but the system cannot support multiple resource reservation modes including customer request mode

Engineering Contradiction:

Improvesupport for multiple resource reservation modesVSAvoidRACS function framework complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the resource reservation functionality into distinct modes (proxy request mode, customer request mode, access configuration mode) with dedicated workflows and interface requirements for each mode. This allows the system to support multiple reservation modes while maintaining a structured, manageable framework where each mode can be independently defined and implemented.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The RACS framework is designed with universal components (RM-PDF, BGF, resource request handling mechanisms) that can serve multiple resource reservation modes. The same core framework structures and functional elements are reused across different reservation modes, enabling multi-functionality without proportionally increasing overall system complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of operation

If detailed interface requirements and workflows are added for customer request mode, then the system's ability to handle customer-initiated resource requests is improved, but the overall system complexity increases

Engineering Contradiction:

Improvecustomer ability to directly initiate resource requestsVSAvoidinterface requirements and workflow complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The Border Gateway Function (BGF) serves as an intermediary between customer premise equipment and the RM-PDF for resource requests. The BGF handles the complexity of interface requirements and workflow management, translating customer requests into standardized formats that the core admission control system can process, thereby improving ease of operation while containing complexity in the intermediary layer.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent establishes preliminary interface requirements and workflow definitions for customer request mode before implementation. By pre-defining the interfaces, message formats, and workflow sequences that CPE must follow, the system enables straightforward customer-initiated requests without requiring complex real-time decision-making, as the framework rules are predetermined.

Inventive Principle:

Principle #10Preliminary action

3Productivity

If resource reservation is enabled in customer request mode, then operational efficiency is enhanced, but the risk of network congestion and policy violations increases

Engineering Contradiction:

Improveoperational efficiency in resource reservationVSAvoidnetwork congestion control and policy compliance

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The RM-PDF implements feedback mechanisms by evaluating resource requests against network policy rules and current resource availability before granting reservations. The system continuously monitors network state and adjusts admission decisions based on feedback from resource status checks, ensuring that operational efficiency is maintained while preventing network congestion and policy violations through dynamic control.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system applies preliminary anti-action by pre-evaluating resource requests against policy rules and network capacity constraints before actual resource allocation occurs. The RM-PDF performs preliminary checks to prevent policy violations and congestion before they happen, rather than reacting after problems arise, thereby maintaining both operational efficiency and network reliability.

Inventive Principle:

Principle #9Preliminary anti-action

AI summary

A resource reservation method in customer request mode in Next Generation Network (NGN) includes: a Resource Mediation Policy Decision Function (RM-PDF) receives a resource request containing resource request parameters through a Border Gateway Function (BGF); the RM-PDF sends an admission installation instruction to the BGF to set admission decision parameters in the BGF for implementing resource reservation when the resource request complies with a customer configuration and network operation policy rules and there is available resource required by the resource request in a transmission network. An NGN Resource and Admission Control System (RACS) supporting resource reservation in customer request mode, and an RM-PDF thereof are also disclosed.
