Solution Overview
Problem
Current mobile devices face issues with conflicting link selection and aggregation policies across cellular and enterprise wireless networks, leading to increased power consumption and resource usage due to the need to maintain multiple interfaces in active states.
Innovation Solution
A system and method for controlling link selection and aggregation across multiple wireless networks based on the location of a mobile device, selectively toggling interfaces to optimize access based on the device's location within a physical environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple wireless interfaces are maintained in active states to support both cellular and enterprise wireless networks, then network access capability is improved, but power consumption and resource usage increase
Solution Approach 1:
The patent implements dynamic interface management where the mobile device selectively activates or deactivates wireless interfaces (cellular and WiFi) based on current network conditions, location, and policy requirements. Instead of maintaining both interfaces permanently active, the system dynamically transitions interfaces between active and inactive states, resolving the contradiction between maintaining network access capability and reducing power consumption.
2Measurement precision
If both cellular and WiFi interfaces are activated to estimate access quality for link selection, then network selection accuracy is improved, but power consumption and air-time usage increase
Solution Approach 1:
The patent applies partial action by selectively activating only the necessary interface for access quality estimation based on current needs. Instead of always activating both cellular and WiFi interfaces for measurement, the system activates only one interface at a time or only the relevant interface according to policy, achieving sufficient measurement accuracy while significantly reducing power consumption and air-time usage.
3Productivity
If HetNet approaches are used to control link selection across networks, then network optimization is improved, but policy conflict with enterprise wireless network operators arises
Solution Approach 1:
The patent implements local quality by applying different selection policies to different network types and locations. Instead of a uniform HetNet approach, the system applies WiFi-preferential policies within enterprise coverage areas and cellular-preferential policies outside those areas. This localized policy application resolves the contradiction by optimizing network selection for each specific context while maintaining compatibility with enterprise operator preferences.

AI summary
Systems, methods, and computer-readable media for controlling link selection and aggregation across multiple wireless networks based on a location of a mobile device are provided. A location of a mobile device in a physical environment can be identified. At least portions of the physical environment can be in wireless range of a first wireless network and a second wireless network. Whether to access network services through either or both the first wireless network and the second wireless network can be determined based on the location of the mobile device in the physical environment. Further, a first interface at the mobile device to the first wireless network and a second interface at the mobile device to the second wireless network can be selectively toggled according to whether it is determined to access the network services through either or both the first wireless network and the second wireless network based on the location.
