Solution Overview
Problem
Existing data transmission methods in multi-network environments face limitations in providing smooth services, especially when handling large data transfers and with the increasing use of various wireless devices, as they often overload a single selected network, leading to inadequate performance.
Innovation Solution
A method and apparatus for simultaneous data transmission over multiple networks, where data is partitioned into partial data and transmitted through two or more networks, with a receiving apparatus designating a transmission network based on received data partials' timing to optimize network state confirmation and control data transmission suspension or resumption.

Engineering Contradiction Analysis
1Device complexity
If only one network is selected from multiple networks to transmit data, then the network selection process is simple, but the load rate of the selected network abruptly increases when large amounts of data are transmitted, leading to inadequate performance
Solution Approach 1:
The data is divided into multiple data packets that can be transmitted through different networks simultaneously. The transmitting apparatus partitions the original data into several segments and sends them over multiple available networks (e.g., Wi-Fi, cellular, Bluetooth) rather than overloading a single network, thereby distributing the load and maintaining transmission performance.
Solution Approach 2:
The patent combines multiple network channels into a unified data transmission system. By merging the capabilities of multiple networks (Wi-Fi, cellular, Bluetooth, etc.), the system achieves higher overall bandwidth and reliability while maintaining simple network selection at the application layer, as the system automatically manages the underlying multiple network paths.
2Productivity
If data is transmitted through multiple networks simultaneously, then the load distribution and transmission performance are improved, but the complexity of managing multiple network paths and confirming network states increases
Solution Approach 1:
The receiving apparatus sends feedback information to the transmitting apparatus about the reception status of data packets from each network. This feedback mechanism allows the transmitting apparatus to confirm network states and adjust transmission strategies dynamically, managing the complexity of multiple network paths through automated state confirmation and adaptation.
Solution Approach 2:
The system implements self-service mechanisms where the transmitting and receiving apparatus automatically manage multiple network paths without requiring complex external control. The apparatus autonomously handle network state confirmation, packet routing decisions, and transmission adjustments based on real-time network conditions, reducing the burden of manual network management.
3Reliability
If network state confirmation is performed frequently to adjust data transmission paths, then the reliability of data transmission is improved, but the overhead of network state monitoring and path adjustment increases
Solution Approach 1:
The system performs network state confirmation periodically rather than continuously, balancing reliability with overhead. Data packets are transmitted through multiple networks with periodic feedback exchanges between transmitting and receiving apparatus, allowing the system to monitor network states at regular intervals and adjust transmission paths without excessive monitoring overhead.

AI summary
A receiving apparatus includes a communication unit to receive partial data partitioned from data transmitted from a transmitting apparatus through two or more networks and transfer network state related information based on the partial data respectively received through each of the two or more networks to the transmitting apparatus through a transmission network to be designated; and a network selection unit to designate one network among the two or more networks as the transmission network for transmitting the network state related information, based on a time of receiving each of the partial data through each of the two or more networks.
