Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile network operators face challenges in managing Wi-Fi offloading due to lack of integration with mobile networks, leading to poor subscriber experience, missed offload opportunities, and increased costs, as traditional base stations struggle to keep pace with growing data traffic demands.
Innovation Solution
A network selection policy server generates and sends enhanced network selection rules to wireless devices, enabling intelligent selection between Wi-Fi and cellular networks based on factors like radio link quality, congestion, and user behavior, allowing for automated and optimized network transitions.

Engineering Contradiction Analysis
1Quantity of substance
If mobile network operators deploy traditional base stations to meet growing data traffic demands, then network capacity increases, but equipment costs and network congestion increase significantly
Solution Approach 1:
The patent combines Wi-Fi network deployment with mobile network operations, integrating Wi-Fi access points into the operator's network infrastructure. This merging allows operators to leverage Wi-Fi's unlicensed spectrum and smaller cell sizes to increase network capacity while avoiding the high equipment costs of traditional base station deployments.
Solution Approach 2:
The patent introduces an intermediary system that manages network selection between cellular and Wi-Fi networks. This intermediary automatically directs traffic to appropriate networks based on congestion levels, capacity requirements, and cost considerations, thereby increasing overall network capacity without proportionally increasing equipment costs.
2Device complexity
If mobile network operators deploy large scale Wi-Fi networks, then equipment costs are reduced, but integration with mobile networks is insufficient leading to poor subscriber experience
Solution Approach 1:
The patent implements feedback mechanisms where the network selection policy server continuously monitors network conditions, subscriber behavior, and offloading performance. This feedback enables dynamic adjustment of network selection rules to optimize subscriber experience while maintaining cost efficiency. The system learns from subscriber patterns and automatically refines its decisions.
Solution Approach 2:
The patent makes the network selection system dynamic by enabling automated, real-time network transitions based on changing conditions. Instead of static manual selection, the system continuously adapts to network congestion, signal quality, and subscriber preferences, thereby improving ease of operation and subscriber experience while maintaining the cost benefits of Wi-Fi deployment.
3Device complexity
If manual Wi-Fi network selection is required, then network integration complexity is reduced, but offload opportunities are missed and utility of Wi-Fi deployments is reduced
Solution Approach 1:
The patent enables self-service network selection where the system automatically manages network transitions without requiring manual user intervention. The network selection policy server autonomously monitors conditions and directs traffic to appropriate networks, thereby capturing offload opportunities while maintaining manageable integration complexity through automated rule-based decision-making.
4Productivity
If automated network selection is implemented, then offload opportunities are maximized, but system complexity and management difficulty increase
Solution Approach 1:
The patent segments the network selection function into distinct modular components: a policy server that generates rules, a network monitor that collects data, and an execution engine that implements decisions. This segmentation allows automated network selection to maximize offload opportunities while managing system complexity through modular, independently manageable components with well-defined interfaces.

AI summary
A method for providing coordinated network selection policies on multiple user equipment devices associated with a subscriber, the method comprising generating, via a processor of a network selection policy server, a first enhanced network selection rule that includes information suitable for causing a first user equipment device to automatically evaluate a condition and determine whether to transition from using a first wireless communication network to using a second wireless communication network, identifying, via the processor of the network selection policy server, the subscriber associated with the first user equipment device, identifying, via the processor of the network selection policy server, a second user equipment device that is associated with the identified subscriber; generating, via the processor of the network selection policy server, a second enhanced network selection rule based on the information included in the first enhanced network selection rule, wherein the second enhanced network selection rule is generated in response to the processor of the network selection policy server identifying the second user equipment device, sending the first enhanced network selection rule to the first user equipment device so as to cause the first user equipment device to automatically evaluate the condition and determine whether to transition from using the first wireless communication network to using the second wireless communication network, and sending the second enhanced network selection rule to the identified second user equipment device.
