Resource Admission Control Adaptation Layer for Fixed Mobile Network Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing resource and admission control systems in fixed and mobile networks lack harmonious integration, making it difficult to implement resource and admission control effectively across different networks, especially for mobile users accessing services through fixed networks.
Innovation Solution
A method and system where a resource and admission control function entity in a fixed network receives and converts request messages from a Policy and Charging Rule Function (PCRF) entity in a mobile network, performing authorization checks and converting policy rules into formats suitable for the fixed network's transport functional entities, enabling efficient resource management and admission control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate resource and admission control systems are used in fixed and mobile networks, then each network can be independently controlled, but harmonious integration and effective resource management across networks cannot be achieved
Solution Approach 1:
The patent introduces an adaptation layer as an intermediary component that sits between the mobile network's PCRF and the fixed network's transport entities. This adaptation layer translates and adapts resource control messages between different network protocols and formats, enabling seamless integration without requiring complete system redesign. The intermediary handles message format conversion, parameter mapping, and protocol adaptation, thus achieving harmonious resource management while preserving the independence of existing network systems.
2Adaptability or versatility
If mobile users access services through fixed networks, then network convergence is achieved, but existing resource control systems cannot effectively manage resources across both networks
Solution Approach 1:
The patent implements parameter changes by dynamically adapting resource control parameters when messages are transmitted between mobile and fixed networks. The adaptation layer modifies message parameters such as QoS requirements, resource allocation parameters, and admission control thresholds to match the target network's expectations. This ensures that resource control decisions made in one network context remain effective when executed in another network environment, maintaining reliability across network boundaries.
3Ease of manufacture
If policy rules are directly applied across different network types, then implementation is simple, but compatibility issues arise between mobile and fixed network protocols
Solution Approach 1:
The patent segments the policy implementation process into distinct functional layers: policy decision layer (mobile network PCRF), adaptation layer (protocol translation), and policy enforcement layer (fixed network transport entities). This segmentation allows each layer to handle specific tasks independently - the mobile network generates policy decisions, the adaptation layer translates them to fixed network formats, and the fixed network enforces them. This modular approach maintains ease of policy implementation while ensuring protocol compatibility through specialized translation functions.
