Selective Network Access for Cellular Congestion Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 3G mobile networks face congestion due to limited data offload from wireless cells to hotspots, primarily because smartphones do not switch to WiFi to conserve battery life, and devices lack accurate geo-location for optimal hotspot access, which is power-intensive and not economical for all devices.
Innovation Solution
Implement a system that determines the wireless cell location and generates a connection policy decision for a wireless communications device to access a wireless hotspot based on factors like battery charge, mobility patterns, data usage, historical success rates, capacity utilization, and subscriber plans, using a policy-driven radio manager and connection policy manager to selectively switch between wireless cells and hotspots.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GPS receiver is enabled to obtain accurate geo-location for optimal hotspot access, then location accuracy is improved, but battery power consumption increases
Solution Approach 1:
The patent introduces wireless cell location determination as an intermediary method between GPS and hotspot access decisions. Instead of directly using GPS for all location needs, the system uses wireless cell location (which consumes less power) as the primary intermediary, and only engages GPS when higher precision is absolutely necessary and justified by the connection policy manager.
Solution Approach 2:
The system dynamically changes the precision parameter of location services based on contextual factors. The connection policy manager adjusts location accuracy requirements according to battery charge levels, mobility patterns, and historical success rates, switching between low-power cell-based location and high-power GPS-based location as needed.
2Productivity
If wireless devices switch to WiFi hotspots to offload data, then network congestion is reduced, but battery power consumption increases
Solution Approach 1:
The system implements feedback loops where the connection policy manager continuously monitors battery charge levels, data usage patterns, and hotspot accessibility. Based on this feedback, it dynamically adjusts connection policies to switch between cellular and WiFi hotspots, ensuring data offload occurs only when it benefits both network congestion reduction and device power conservation.
Solution Approach 2:
The connection policy is made dynamic rather than static. The system adapts hotspot switching decisions in real-time based on changing conditions including battery status, mobility patterns, historical success rates, and current network capacity utilization, allowing optimal balance between data offload and power consumption.
3Productivity
If network operators deploy WiFi hotspots in cells with capacity overload, then network congestion management is improved, but device complexity increases
Solution Approach 1:
The system enables devices to autonomously manage their own connection decisions without requiring complex operator intervention. The connection policy manager on the device side uses locally available information (battery status, mobility patterns, historical data) to make intelligent switching decisions, reducing the operational complexity burden on the network operator while improving congestion management.
