WLAN Manager Detecting Cellular Congestion for Network Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of modern telecommunication devices often lack awareness of available Wi-Fi networks, leading to network congestion, interference, and 'dead spots' where cellular service is unavailable, resulting in poor quality of service and user experience.
Innovation Solution
Integration of a WLAN manager component in telecommunication devices to detect and notify users of available Wi-Fi networks, allowing timely decisions on communication session management and switching between cellular and Wi-Fi networks based on quality of service metrics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users rely solely on cellular networks for communication, then cellular service coverage is maintained, but network congestion and interference increase in densely-populated metropolitan regions
Solution Approach 1:
The patent introduces Wi-Fi networks as an intermediary communication channel between mobile devices and the network infrastructure. When cellular networks experience congestion or interference, the system automatically routes traffic through available Wi-Fi access points, effectively using Wi-Fi as a mediator to bypass harmful conditions in the cellular network and maintain communication reliability.
2Adaptability or versatility
If Wi-Fi networks are deployed to fill cellular coverage gaps, then alternative broadband access is provided, but WLAN service boundaries become invisible and undiscoverable to users
Solution Approach 1:
The patent implements a feedback mechanism where the system continuously monitors cellular network quality metrics (signal strength, data rates, block error rates) and automatically switches to Wi-Fi networks when degradation is detected. This feedback loop ensures that users benefit from seamless network adaptation without needing to manually discover or configure Wi-Fi networks, as the system autonomously responds to network conditions.
Solution Approach 2:
The patent enables the communication system to automatically manage network selection and switching between cellular and Wi-Fi networks without requiring user intervention. The device autonomously discovers available Wi-Fi networks, evaluates their suitability, and transitions connections as needed, making the system self-sufficient in managing network adaptability and eliminating the need for users to actively seek out Wi-Fi coverage areas.
3Reliability
If automatic network switching is implemented, then quality of service is improved, but device complexity increases due to integration of WLAN manager component
Solution Approach 1:
The patent integrates WLAN manager functionality into the existing mobile device architecture, allowing the same hardware components (wireless transceivers, processors, memory) to serve multiple functions: cellular communication, Wi-Fi scanning, network evaluation, and automatic switching. By making the device multi-functional and leveraging existing infrastructure, the patent avoids significant complexity increases while achieving reliable automatic network management.
Data Source
AI summary
A wireless local area network (WLAN) management procedure for a telecommunication device is disclosed. A WLAN management entity is operable to detect a communication event associated with a voice call, a video call, or a data transfer session, and then determine a current state of a cellular network. When the current state of the cellular network is deemed problematic, is otherwise unavailable, and/or when an alternative, higher-throughput WLAN is available, the WLAN management entity identifies available WLANs for enabling the corresponding communication. Subsequently, the WLAN management entity generates a notification, presenting an option for selecting an available WLAN, based in part on the current state of the cellular network.
