Network Node Selecting Heterogeneous Networks via Multi-Factor Rating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional endpoint devices employ rudimentary heuristics for selecting between multiple wireless networks, which can lead to connectivity issues due to prioritizing networks based on speed, ignoring factors like coverage and user capacity, resulting in suboptimal communication performance.
Innovation Solution
A computer-implemented method for selecting between heterogeneous networks by acquiring and prioritizing constraints based on current operating modes, generating ratings for each network, and selecting the optimal network for data transmission or reception based on these ratings.

Engineering Contradiction Analysis
1Speed
If conventional heuristics prioritize WiFi network over cellular network based on speed, then communication speed is improved, but connectivity reliability deteriorates when WiFi coverage is limited
Solution Approach 1:
The patent changes the selection parameters from simple speed-based heuristics to a multi-factor rating system that evaluates both speed and coverage parameters. The system dynamically adjusts network selection by considering multiple parameters simultaneously, resolving the contradiction between prioritizing speed while maintaining reliability.
Solution Approach 2:
The patent implements dynamic network selection where the endpoint device continuously evaluates multiple networks and switches between them based on current conditions. This dynamic approach allows the system to maintain high speed when WiFi is available while ensuring reliability by switching to cellular when WiFi coverage is limited, rather than using static prioritization.
2Device complexity
If endpoint devices use simple heuristic rules for network selection, then device complexity is reduced, but adaptability to different network conditions deteriorates
Solution Approach 1:
The patent segments the network selection process into distinct rating components for different factors (speed, coverage, etc.). Each network is evaluated separately on multiple dimensions, and the results are combined to produce an overall rating. This segmentation allows complex multi-factor evaluation without overwhelming device complexity.
Solution Approach 2:
The patent introduces a rating system as an intermediary layer between raw network parameters and the final selection decision. This intermediary translates multiple network characteristics into a unified rating that guides network selection, simplifying the decision process while maintaining adaptability to various network conditions.

AI summary
A node within a wireless endpoint device may be coupled to multiple heterogeneous networks simultaneously. The node is configured to select between the different networks based on various constraints associated with the endpoint device, applications executing on the endpoint device, traffic routed by the endpoint device, and constraints associated with the multiple networks. Based on these different constraints, and based on the current operating mode of the node, the node rates each network, and then selects the network with the highest rating to be used for routing purposes.
