Mobile Device Wi-Fi Cellular Hybrid Service Registration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile technologies face challenges in providing seamless voice and data services in areas with poor cell coverage, as they require constant connection to cellular networks for functionality, limiting usability when out of range.
Innovation Solution
A mobile device system that registers with a cellular network for location tracking and limited communication, allowing voice and data transactions over Wi-Fi networks, with the cellular network used only for registration, paging, and sending pre-defined messages when not connected to Wi-Fi, ensuring users receive notifications and can reconnect at convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mobile devices require constant connection to cellular networks for voice and data services, then service reliability is improved, but usability in areas with poor cell coverage deteriorates
Solution Approach 1:
The patent segments the communication functionality into two independent parts: cellular network connection for registration and notification, and Wi-Fi connection for voice and data transactions. This segmentation allows the device to maintain service reliability through cellular registration while enabling usability in poor coverage areas by using Wi-Fi for actual communication transactions.
Solution Approach 2:
The patent introduces Wi-Fi network as an intermediary for voice and data transactions. Instead of requiring direct cellular connection for all communications, the device registers with the cellular network and uses Wi-Fi as an intermediary channel for actual transactions, allowing service to continue in areas with poor cellular coverage.
2Ease of operation
If mobile devices use Wi-Fi for voice and data transactions, then usability in poor coverage areas is improved, but service continuity when moving between networks deteriorates
Solution Approach 1:
The patent implements feedback mechanisms where the device continuously monitors its connection status to both cellular and Wi-Fi networks. When moving between networks or when connection quality changes, the system receives feedback and automatically adjusts by maintaining cellular registration for notification while switching Wi-Fi connections as needed, ensuring service continuity.
Solution Approach 2:
The patent makes the communication system universal by enabling it to function through multiple network types. The device can use cellular network for registration and notification, Wi-Fi for transactions when available, and automatically adapt to use available networks in different locations, maintaining service continuity across diverse environments.
3Device complexity
If cellular network is used only for registration and notifications, then device complexity is reduced, but loss of communication capability when disconnected from Wi-Fi increases
Solution Approach 1:
The patent applies preliminary action by having the device register with the cellular network in advance before actual communication transactions. This registration establishes the device's identity and location, enabling the network to page and notify the device even when it's disconnected from Wi-Fi, preventing complete loss of communication capability.
Solution Approach 2:
The patent implements self-service by enabling the device to autonomously manage its own communication capabilities. When disconnected from Wi-Fi, the device automatically falls back to using cellular network for notifications and can initiate reconnection to Wi-Fi without user intervention, maintaining communication capability through self-managed network switching.
Data Source
AI summary
A mobile device can be configured to connect to a telecommunications network via a wireless fidelity network device. The mobile device can register with a channel of a base station, which can indicate where the mobile device is located in relation to the base station. Additionally, the mobile device can communicate with other mobile devices via the wireless fidelity network device. In response to an indication that the mobile device is no longer connected to the wireless fidelity network device, notifications can be sent to the mobile device or other mobile devices regarding additional communication.
