Roaming Network Selection Using Server-Based Preference Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network selection methods are inadequate for seamless and user-friendly selection of communication networks, especially when faced with a growing number of available networks, including private networks and satellite networks, and do not account for user preferences, pricing, or technical capabilities.
Innovation Solution
A method and server device that utilize a network selection server to determine communication networks based on predefined criteria, including user preferences, pricing, and technical capabilities, using position data and data from databases like GSMA IR.21, and optionally employing AI/ML for predictive network selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the list of available networks is extended to include private networks and satellite networks, then the versatility and coverage options are improved, but the complexity of network selection and user handling becomes worse
Solution Approach 1:
The patent introduces a network selection server as an intermediary between the terminal device and the available networks. This server automatically determines which networks are suitable based on predefined criteria (location, network type, coverage) and provides recommendations to the terminal device, thereby reducing the complexity of network selection while maintaining extensive network coverage options including private and satellite networks
2Ease of operation
If automatic network selection based on predefined criteria is implemented, then the ease of operation is improved, but the loss of information about network details becomes worse
Solution Approach 1:
The patent implements a feedback mechanism where the network selection server provides recommendations based on predefined criteria, and the terminal device can request additional information about specific networks. The server responds with detailed network information including coverage areas, network types, and selection rationale, thereby maintaining information transparency while simplifying the selection process
3Adaptability or versatility
If transparent satellite network selection is added for remote locations, then the adaptability to diverse environments is improved, but the device complexity increases
Solution Approach 1:
The patent makes the network selection server universal by enabling it to handle multiple network types (mobile networks, private networks, satellite networks) through a unified approach. The server uses the same predefined criteria and decision-making process for all network types, allowing the terminal device to seamlessly select from diverse networks without increasing complexity at the device level
