Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless network technologies suffer from isolated cells that disrupt data links when user stations move between different wireless network cells, leading to inefficient bandwidth usage and poor user experience due to the need for re-establishing data links and retransmitting data.
Innovation Solution
A method for network convergence across wireless cells, involving the construction of convergence link tables in access points and a user management system to manage user location information and configure data forwarding, allowing seamless data transmission across cells by maintaining continuous data streams through IP-in-IP encapsulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless network cells operate independently with isolated data links, then each cell can maintain simple and stable data transmission, but data links are interrupted when user stations move between cells, requiring re-establishment and retransmission
Solution Approach 1:
The patent introduces a user management system as an intermediary that coordinates between multiple access points. This system maintains user location information and manages convergence link tables, enabling seamless data link continuity across cell boundaries without requiring complex peer-to-peer coordination between access points
Solution Approach 2:
The patent implements IP-in-IP encapsulation where the original data packet is nested within a new IP packet. This nested structure allows the inner packet to maintain its original routing information while the outer packet provides the new routing path through the convergence link table, enabling continuous transmission across cells without exposing the underlying complexity
2Productivity
If user stations re-establish data links after moving cells, then network configuration remains simple, but bandwidth is wasted due to retransmission of already transmitted data
Solution Approach 1:
The patent establishes convergence link tables that maintain continuous data transmission paths when user stations move between cells. The user management system updates these tables to reflect current user locations, ensuring that data flow continues uninterrupted without stopping for re-establishment, thereby eliminating redundant retransmissions and optimizing bandwidth utilization
Solution Approach 2:
The user management system implements feedback mechanisms by continuously tracking user station locations and updating convergence link tables accordingly. This feedback loop ensures that the network dynamically adapts to user movement, maintaining optimal data transmission paths and preventing bandwidth waste from outdated routing information
3Adaptability or versatility
If multiple wireless network technologies are integrated for network convergence, then user experience and bandwidth utilization improve, but the complexity of managing different physical layer and MAC layer standards increases
Solution Approach 1:
The patent segments the network management function by separating the user management system from individual access points. This segmentation allows each access point to handle its own physical layer and MAC layer operations independently while the centralized user management system handles the convergence logic, making it easier to integrate multiple wireless standards without increasing overall system complexity
