Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multi-band radios select networks based on signal strength, which is inadequate for users in motion, as some small cells and WiFi hotspots cannot sustain connections at high velocities, leading to communication disruptions.
Innovation Solution
The system uses a GPS receiver to determine the velocity of a mobile device, selecting between network types capable of handling active sessions (macro-cell networks) and those with reduced or no handoff capacity (small cells or WiFi) based on movement and signal strength, ensuring seamless communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If conventional multi-band radios select networks based on signal strength, then network selection is simple, but communication reliability deteriorates for users in motion
Solution Approach 1:
The patent changes the selection parameter from signal strength alone to a composite parameter that includes velocity information. The radio device determines its velocity and uses this additional parameter to select appropriate networks, thereby maintaining communication reliability for moving users without significantly increasing system complexity.
Solution Approach 2:
The patent introduces velocity as an intermediary parameter that mediates between the radio device and network selection. By determining velocity and using it as a basis for network selection, the system resolves the contradiction between simple selection criteria and reliable communication for moving users.
2Productivity
If small cells or WiFi hotspots are used for stationary users, then bandwidth efficiency is improved, but connection stability deteriorates for high velocity users
Solution Approach 1:
The patent applies different network types to different user conditions: small cells or WiFi hotspots for stationary users (local optimization for bandwidth efficiency), and macro-cell networks for moving users (local optimization for connection stability). This local quality differentiation resolves the contradiction between bandwidth efficiency and connection stability.
Solution Approach 2:
The patent makes network selection dynamic by incorporating velocity information. The system adapts network selection based on the user's motion state, switching between small cells/WiFi for stationary conditions and macro-cell networks for moving conditions, thereby resolving the contradiction between bandwidth efficiency and connection stability.
3Reliability
If macro-cell networks are used for all users, then connection stability is maintained, but bandwidth utilization deteriorates for stationary users
Solution Approach 1:
The patent applies different network types to different user conditions: macro-cell networks for moving users (ensuring connection stability), and small cells or WiFi hotspots for stationary users (optimizing bandwidth utilization). This local quality differentiation resolves the contradiction between connection stability and bandwidth utilization.
Solution Approach 2:
The patent makes network selection dynamic by incorporating velocity information. The system adapts network selection based on the user's motion state, switching between macro-cell networks for moving conditions and small cells/WiFi for stationary conditions, thereby resolving the contradiction between connection stability and bandwidth utilization.
4Reliability
If network selection is based on velocity, then communication reliability for moving users is improved, but device complexity increases
Solution Approach 1:
The patent changes the selection parameter from signal strength alone to a composite parameter that includes velocity information. The radio device determines its velocity and uses this additional parameter to select appropriate networks, thereby maintaining communication reliability for moving users without significantly increasing system complexity.
Solution Approach 2:
The patent implements self-service by having the radio device determine its own velocity and autonomously select appropriate networks based on this information. This self-directed network selection improves communication reliability for moving users while minimizing the need for complex external control systems.
