Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In heterogeneous network environments where multiple wireless technologies coexist, current methods for data service access are passive and lack service provider control, leading to increased network load and stability issues due to inefficient network usage and high investment costs.
Innovation Solution
A network device with a data relay unit and re-routing controller that divides data and transmits it through multiple networks, allowing for re-routing of data over an alternative network if the initial network connection becomes abnormal, ensuring seamless data transmission and improved service reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is transmitted through a single network interface, then the transmission path is simple, but the service stability deteriorates when the network connection becomes abnormal
Solution Approach 1:
The patent segments data transmission by dividing data into multiple packets and transmitting them through different network interfaces (e.g., WiFi and cellular networks). This segmentation allows the system to maintain service stability by switching between network paths when one becomes abnormal, directly resolving the contradiction between reliability and complexity.
Solution Approach 2:
The patent changes the network transmission parameter by dynamically selecting different network interfaces based on connection status. When the primary network becomes abnormal, the system switches to an alternative network interface, thereby maintaining service stability without requiring complex pre-configured redundancy for all possible failure scenarios.
2Reliability
If multiple networks are used for data transmission, then service stability is improved, but the network load and investment costs increase
Solution Approach 1:
The patent applies partial action by maintaining connections to multiple networks only when necessary for service continuity. The system uses primary network interface for normal operation and activates alternative network interfaces only when the primary connection becomes abnormal, thereby improving service stability without continuously incurring the costs of maintaining multiple active network connections.
Solution Approach 2:
The patent introduces a network interface selector as an intermediary that manages data transmission across multiple networks. This intermediary component coordinates network selection and switching, allowing the system to leverage multiple networks for stability while optimizing resource usage and reducing overall network investment costs through intelligent routing decisions.
3Ease of operation
If passive network access method is used, then the implementation is simple, but the service provider loses controllability over network selection
Solution Approach 1:
The patent transforms the static passive network access method into a dynamic system where the network interface selector can actively choose between different network interfaces based on service requirements and network conditions. This dynamic approach maintains implementation simplicity through automated selection logic while providing service providers with controllability over network usage patterns and data routing decisions.
Solution Approach 2:
The patent implements feedback mechanisms where the network interface selector monitors network connection status and performance metrics to make intelligent routing decisions. This feedback-driven approach allows the system to maintain simple automated operation while providing service providers with controllability through configurable policies and real-time network status awareness.

AI summary
The heterogeneous network based-simultaneous data transmission service method includes identifying an access state with a reception device by a network device configured to relay data transmission/reception between a particular reception device and a particular transmission device, the network device being located in a particular network, when the access state with the reception device is abnormal, making a request for re-routing particular data transmitted from the transmission device to the reception device, and when the transmission device configured to transmit/receive particular partial data divided from one particular data through two or more network interfaces receives the re-routing request from the network device corresponding to a particular network interface, transmitting the particular partial data according to the re-routing request to the reception device through another network interface of the two or more network interfaces.
