5G Roaming Network Selection via User Profile Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current roaming systems in 5G networks fail to consider user expectations and network capabilities when selecting a new operator, leading to dissatisfaction as the selection is based on static predetermined lists without accounting for user habits or actual network offerings.
Innovation Solution
A method that creates a user's network profile by combining past usage data and inferred future needs, matching it with Virtual Network Function capabilities of local networks, and generating a ranked list of suitable roaming networks for selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a static predetermined list of preferred operators is used for network selection, then the roaming process is simple and automated, but user satisfaction deteriorates because user expectations and network capabilities are not considered
Solution Approach 1:
The patent transforms the static predetermined operator list into a dynamic selection process. The system continuously monitors user consumption habits, service usage patterns, and network performance metrics to adaptively generate and update the preferred operator list in real-time, allowing the roaming selection to evolve based on actual user needs and network conditions rather than relying on fixed pre-configured lists
Solution Approach 2:
The patent implements feedback mechanisms where user satisfaction metrics, service quality indicators, and consumption patterns are continuously collected and fed back into the network selection algorithm. This feedback loop enables the system to learn from past roaming experiences and adjust future network selections to better match user expectations and deliver improved service quality
2Device complexity
If network selection is based on Service Level Agreement between operators, then inter-operator relationships are simplified, but the ability to meet user-specific service needs deteriorates
Solution Approach 1:
The patent segments the network selection process into multiple independent evaluation dimensions: user consumption habits analysis, service usage pattern recognition, network capability assessment, and real-time performance monitoring. Each dimension is evaluated separately and aggregated to form a comprehensive network score, allowing the system to maintain simple operator agreements while achieving complex, personalized service matching through multi-criteria decision analysis
3Extent of automation
If the user is not implicated in network selection, then the roaming process is fully automated, but the service offered may not align with user expectations
Solution Approach 1:
The patent enables the system to automatically discover and utilize user preferences without direct user intervention. The system monitors user behavior patterns, service usage habits, and consumption metrics to infer user preferences autonomously, then applies these inferred preferences to network selection decisions, effectively making the system self-aware of user needs while maintaining full automation
Solution Approach 2:
The patent performs preliminary analysis of user consumption habits and service usage patterns before the actual roaming network selection occurs. By pre-processing user data, establishing baseline preferences, and predicting future service needs in advance, the system prepares personalized network selection criteria that are then applied when roaming decisions must be made, ensuring user preferences are considered without requiring real-time user input

AI summary
There is described therein a method of roaming between 5G networks operator for selecting a network operator in a visited country when a mobile network user exits an area covered by a home network operator to enter the visited country covered by a plurality of visited network operators. This method of roaming is based on the concordance between the VNF supported by the visited country network and the network profile of the user. The network profile of the user embeds both the functions commonly chained in his home network to deploy the services corresponding to his usage and the functions required in the visited country network to perform the services desired by the user. Therefore, by matching this profile with VNF capabilities deployed by a network the invention allows a better user satisfaction in roaming situations providing them with the most suitable network.
