Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience and inefficiency when switching between multiple devices to access and transfer telecommunications and online services, requiring manual disconnection and reconnection of services, which is time-consuming and cumbersome.
Innovation Solution
A method and apparatus utilizing near field communication (NFC) to seamlessly transfer active online services from one user equipment (UE) to another, enabling quick and intuitive device switching by establishing a wireless link and transferring necessary information, such as identifiers and authentication details, to coordinate the transfer of services like voice calls, messaging, and other online services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual disconnection and reconnection of services is used when switching devices, then service transfer can be completed, but the process is time-consuming and cumbersome
Solution Approach 1:
The patent introduces a service platform as an intermediary that coordinates service transfer between devices. The platform receives transfer requests from the first device, manages the disconnection and reconnection processes, and ensures seamless service continuity. This mediator automates the manual steps and reduces the time required for service transfer.
Solution Approach 2:
The system performs preliminary actions by establishing service context and authentication information in advance on the first device. When switching devices, this pre-prepared information is quickly transferred to the second device, eliminating the need for time-consuming re-authentication and service setup procedures.
2Reliability
If multiple devices are kept active simultaneously to ensure service availability, then service access is maintained, but battery life is reduced
Solution Approach 1:
The service platform acts as a central coordinator that maintains service connections. When a device is inactive, the platform keeps the service connection alive on the active device rather than requiring both devices to maintain simultaneous connections. This eliminates redundant power consumption while ensuring service availability through the platform's coordination.
Solution Approach 2:
The patent extracts the service connection management from individual devices and centralizes it on the service platform. This allows the platform to optimize resource allocation, keeping only one device connected at a time while maintaining service availability, thereby reducing overall energy consumption across multiple devices.
3Speed
If seamless device switching is implemented using NFC, then transfer speed is improved, but device complexity increases
Solution Approach 1:
The service platform serves as an intermediary that handles the complex coordination logic for seamless device switching. While individual devices need NFC capability, the heavy lifting of managing service context transfer, authentication, and connection coordination is offloaded to the platform, preventing excessive complexity from accumulating in each device.
Solution Approach 2:
The patent implements a universal service platform that handles multiple service types (telecommunications, online services, etc.) through a single coordinated mechanism. This multi-functional approach allows seamless switching across different service categories without requiring separate complex systems for each service type, thereby managing overall device complexity.

Data Source
AI summary
An approach is provided for switching devices using near field communication by transferring services. A first device executes an online service. The first device initiates communication to a second device over a near field communication link during the execution of the online service to coordinate the transfer of information relating to the online service. The first device initiates the transfer of information relating to the online service to the second device for execution of the online service by the second device based on the communication.
