Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cellular-telephone networks often experience performance degradation due to high user density, leading to service degradation and customer dissatisfaction, as existing methods do not effectively manage network overload and provide alternative communication solutions.
Innovation Solution
A system that determines an electronic device's approximate location and provides a list of available networks and access credentials via the cellular-telephone network, allowing seamless transition to alternative networks like Wi-Fi hotspots using IEEE 802.11 protocol, based on communication criteria such as proximity, signal strength, and security, to maintain service quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users aggregate in a small region using cellular-telephone network, then communication service is provided, but network performance becomes constrained and degraded
Solution Approach 1:
The system dynamically changes communication parameters by switching between cellular and Wi-Fi networks based on network conditions. When cellular network performance degrades due to high user density, the system transitions to alternative Wi-Fi networks, effectively changing the communication parameter from cellular-only to multi-network mode
Solution Approach 2:
The computer system acts as an intermediary that manages network selection and transition. It determines device location, identifies available Wi-Fi networks, provides access credentials, and coordinates the seamless transition between cellular and Wi-Fi networks, mediating the complex network switching process
2Ease of operation
If cellular network is used for communication, then service is provided, but network overload occurs leading to service degradation
Solution Approach 1:
The system performs preliminary actions by determining device location and identifying available Wi-Fi networks before cellular network overload occurs. Access credentials are pre-provisioned, enabling rapid transition to Wi-Fi networks when cellular performance degrades, rather than waiting for failure
Solution Approach 2:
The network selection system is dynamic rather than static. It continuously monitors cellular network performance and automatically transitions between cellular and Wi-Fi networks based on real-time conditions, making the communication system adaptable to changing network loads and performance levels
3Productivity
If alternative networks are provided for seamless transition, then network overload is mitigated, but system complexity increases
Solution Approach 1:
The system provides self-service by automatically determining device location, identifying suitable Wi-Fi networks, selecting the best network based on criteria, and transitioning without user intervention. The complex network management tasks are handled autonomously by the communication management system
Solution Approach 2:
The communication management system performs multiple functions: location determination, network scanning, network evaluation, credential management, and seamless transition coordination. This multi-functional approach consolidates complex network management capabilities into a single integrated system

AI summary
An electronic device receives a list of available networks (which may be other than the cellular-telephone network and may use a communication technique other than a cellular-telephone communication technique) and associated access credentials via a cellular-telephone network. For example, a base station in the cellular-telephone network may track the location of the electronic device, and may provide the list to the electronic device when the cellular-telephone network performance is constrained or degraded. In response to receiving the list, the electronic device may select a network from the available networks based on a communication criterion, such as: proximity to the electronic device, a signal strength, security, and/or communication quality. Information specifying this selection may be provided via the cellular-telephone network, and then instructions that transition communication with the electronic device from the cellular-telephone network to the selected network may be received.
