Connection Manager for Wi-Fi and Cellular Quality-Based Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices often automatically connect to available Wi-Fi networks without considering their performance, leading to poor user experiences due to slow connections, connection interruptions, and reduced battery life, especially when network load is high or signal quality is inadequate.
Innovation Solution
A connection manager on the mobile device determines quality metrics for both cellular and Wi-Fi networks based on contextual information and signal characteristics, comparing them against network policies to selectively connect to the higher-performing network, thereby optimizing data routing and conserving battery life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If mobile devices automatically connect to available Wi-Fi networks, then connection availability is improved, but connection quality deteriorates due to network load and signal issues
Solution Approach 1:
The connection manager dynamically evaluates Wi-Fi network quality metrics (signal strength, network load, bandwidth) in real-time and adaptively switches between Wi-Fi and cellular connections based on current conditions, rather than statically preferring Wi-Fi. This dynamic adaptation resolves the contradiction by maintaining connection availability while ensuring connection quality through intelligent network selection.
2Adaptability or versatility
If mobile devices connect to Wi-Fi networks with high load or poor signal, then connection coverage is improved, but data throughput deteriorates
Solution Approach 1:
The connection manager continuously monitors feedback metrics including signal strength, network load, and actual data throughput of Wi-Fi networks. Based on this feedback, it intelligently determines whether to connect to a Wi-Fi network or switch to cellular, ensuring that connection coverage is maintained while data throughput requirements are met through real-time performance assessment.
3Loss of energy
If mobile devices prioritize Wi-Fi connection, then network cost is reduced, but battery consumption increases due to connection management overhead
Solution Approach 1:
The connection manager performs preliminary evaluation of Wi-Fi network quality metrics (signal strength, network load, bandwidth) before attempting connection. By assessing network suitability in advance, it avoids connecting to poor-quality Wi-Fi networks that would require excessive power for maintaining connections and data transfers, thus reducing overall battery consumption while still prioritizing cost-effective Wi-Fi connectivity when appropriate.
4Reliability
If mobile devices manually evaluate network quality before connection, then connection quality is improved, but device complexity increases
Solution Approach 1:
The connection manager implements self-service by autonomously evaluating Wi-Fi network quality metrics, comparing them against cellular network conditions, and making connection decisions without user intervention. This self-managing approach improves connection quality through intelligent evaluation while minimizing perceived device complexity by handling all connection management tasks automatically in the background.

AI summary
Aspects of policy-defined connection management of opportunistic network capacity are described. In some aspects, a mobile device having a connection manager may be configured to determine, based on a wireless network policy of the mobile device, contextual information for a connection available through an access point (AP) of a wireless local area network (WLAN) associated with a mobile network operator (MNO). The connection manager measures signal-related characteristics of the WLAN connection and determines, based on the contextual information and the characteristics, a first quality metric. The connection manager also measures second signal-related characteristics of a connection available through a base station of a cellular network associated with the MNO and determines, based on the characteristics, a second quality metric. Based on a comparison of the quality metrics, the connection manager connects the mobile device to the WLAN through the AP or the cellular network through the base station.
