Service Distribution System for IoT Device Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current IoT systems lack the ability to seamlessly transfer services among multiple terminal devices due to hardware, system, and manufacturer differences, limiting their inter-device communication and user experience.
Innovation Solution
A service distribution system that obtains service data, device capability information, and status information to determine the most suitable terminal device for executing a target service, allowing for flexible and dynamic service execution across multiple devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If device-centric control is used with specific correspondence between service and device, then device control capability is improved, but service transfer ability among multiple terminal devices deteriorates
Solution Approach 1:
The patent introduces a service management function as an intermediary layer between the user and multiple terminal devices. This service management function receives service requests, determines target terminal devices based on device capability information and status information, and manages service execution across devices. This mediator resolves the contradiction by enabling service transfer without requiring direct device-to-device communication, thus maintaining ease of operation while improving service transfer ability.
Solution Approach 2:
The service management function is designed with multi-functionality to handle various service types across different terminal devices. It can determine target terminal devices for different service scenarios by evaluating device capabilities and statuses, making the system adaptable to diverse service transfer needs while maintaining a unified control approach.
2Device complexity
If centralized control system is used to manage all smart households, then system integration capability is improved, but device interworking flexibility deteriorates
Solution Approach 1:
The patent segments the control system into two parts: a centralized service management function that handles high-level service routing and device selection, and distributed terminal devices that execute specific services. This segmentation allows the centralized system to maintain integration capability while delegating flexibility to individual devices, resolving the contradiction between system integration and device interworking flexibility.
3Reliability
If service execution is assigned to a single fixed device, then service execution reliability is improved, but service execution flexibility deteriorates
Solution Approach 1:
The patent implements dynamic service execution assignment where the target terminal device is determined based on real-time device capability information and status information. The service management function can dynamically select the most appropriate device for service execution, ensuring both reliability (by selecting capable devices) and flexibility (by adapting to changing device states). This dynamic approach resolves the contradiction between fixed assignment reliability and flexible assignment adaptability.
Data Source
AI summary
A method for service decision distribution includes obtaining, by a service distribution system, service data associated with a target service is triggered, where the service data includes service type information and user information, obtaining, by the service distribution system during a determining period of the target service, device capability information and device status information of a plurality of terminal devices associated with the user information, determining, by the service distribution system based on the service type information, the device capability information, and the device status information of the terminal devices, a target terminal device that is in the terminal devices and that is used to execute the target service or a target moment for executing the target service to implement service transfer among multiple terminal devices.
