Solution Overview
Problem
Existing network access technologies fail to optimize cost-effectiveness and performance across cellular, wireless, and wireline networks, particularly for mobile devices that need to switch between networks quickly, leading to potential service disruptions and increased costs.
Innovation Solution
A network optimization system for mobile devices that uses a combination of GPS, speed thresholds, and network interface management to prioritize and seamlessly switch between cellular, wireless, and wireline networks based on mobility and portability modes, optimizing handoffs and reducing service disruptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the mobile device uses cellular network for high-speed mobility, then network access speed and service continuity are improved, but network access cost increases
Solution Approach 1:
The system dynamically adjusts network selection based on real-time device speed measurements. When speed exceeds a threshold, cellular network is selected for fast handoff; when speed is below threshold, wireless or wireline networks are selected for cost efficiency. This dynamic adaptation resolves the contradiction by matching network type to mobility conditions.
Solution Approach 2:
The system changes the network selection parameter based on device speed parameter. By monitoring speed as a variable parameter and using it to determine network type selection, the system optimizes both performance and cost according to actual mobility conditions rather than using a fixed network selection strategy.
2Loss of energy
If the mobile device frequently switches between networks, then network cost is reduced, but service disruption increases
Solution Approach 1:
The system performs preliminary speed assessment before network selection to anticipate the need for fast handoff. By evaluating device speed in advance and pre-selecting appropriate networks, the system avoids last-minute switching that would cause service disruption, thus maintaining both cost efficiency and service continuity.
Solution Approach 2:
The system continuously monitors device speed and uses this feedback to adjust network selection decisions. This closed-loop control ensures that network switching occurs only when appropriate based on actual mobility conditions, preventing unnecessary switches that would disrupt service while still optimizing cost.
3Loss of energy
If the mobile device prioritizes cost-effective networks, then network access cost is reduced, but network access speed decreases
Solution Approach 1:
The system dynamically selects between cost-effective networks and high-speed networks based on real-time speed measurements. This dynamic selection allows the system to prioritize cost efficiency during low-mobility periods while automatically switching to high-speed cellular networks when rapid handoff is required, thus resolving the speed-cost tradeoff.
4Reliability
If the mobile device uses cellular network for all conditions, then service continuity is maintained, but network access cost increases
Solution Approach 1:
The system changes network selection based on the parameter of device speed. By using speed as a decision variable, the system maintains service continuity through cellular networks only when necessary (high speed conditions) while selecting cost-effective wireless or wireline networks during low-mobility conditions, thus optimizing both reliability and cost.
