Traffic Hub System for Roaming QoS Policy Enforcement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems face challenges in providing a seamless and efficient quality of service in roaming wireless networks, requiring complex negotiations between home and roaming networks, leading to delays and additional fees for users.
Innovation Solution
A traffic hub system is introduced to negotiate bandwidth and quality of service based on policies defined by the home network, allowing for easy and quick service provision without direct involvement from the home network, using a traffic hub system positioned between the roaming and home wireless networks to manage data traffic and enforce policies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex negotiations between home and roaming networks are implemented to ensure quality of service, then service reliability is improved, but system complexity and processing time increase
Solution Approach 1:
The patent introduces a roaming support node as an intermediary component that centralizes the negotiation and management of quality of service policies between home and roaming networks. This mediator handles policy enforcement, bandwidth management, and service level agreement verification, eliminating the need for complex direct negotiations between multiple network entities while ensuring reliable quality of service delivery
2Adaptability or versatility
If direct negotiation between home and roaming networks is performed, then service customization is improved, but processing time and user delay increase
Solution Approach 1:
The patent implements preliminary action by pre-configuring quality of service policies, bandwidth allocations, and service level agreements in the roaming support node before actual data transmission occurs. The system establishes service parameters, enforces policies, and manages bandwidth reservations in advance, enabling rapid service delivery without real-time negotiation delays while maintaining customization capabilities
3Adaptability or versatility
If multiple policy servers and roaming-related policies are added to home wireless network, then service control capability is improved, but device complexity and implementation difficulty increase
Solution Approach 1:
The patent extracts the complex policy management functionality from the home wireless network core and consolidates it into a dedicated roaming support node. This extraction removes the burden of implementing multiple policy servers and complex roaming-related policies from the home network infrastructure, simplifying deployment while maintaining comprehensive service control capabilities through the specialized roaming support node
