Solution Overview
Problem
Existing data transmission methods in multi-network environments face challenges in providing seamless services, especially when large capacity data is transmitted, as they are not suited for environments with various wireless devices and lack handover functionality in networks like WiFi, leading to increased load and connection issues.
Innovation Solution
A system that allows data transmission through multiple networks, including WiFi and 3G, by dividing data into partials and transmitting them through the most suitable networks based on available bandwidth, connection errors, and delay values, ensuring seamless continuity by switching between networks as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If data is transmitted through a single selected network, then the transmission path is simple, but the load factor of the network rapidly increases when large capacity data is transmitted
Solution Approach 1:
The patent segments data transmission across multiple networks (first network and second network) rather than relying on a single network. The transmitting device divides data into multiple packets and transmits them through different networks simultaneously, distributing the load and preventing any single network from becoming overloaded.
2Ease of operation
If only one network is selected for data transmission, then the network selection process is simple, but seamless data service cannot be provided when large capacity data is transmitted
Solution Approach 1:
The patent implements dynamic network selection and switching capabilities. The transmitting device monitors network status (bandwidth, delay, error rates) in real-time and dynamically adjusts which network transmits which data packets. The receiving device similarly dynamically switches between networks to maintain seamless data reception, ensuring service continuity even when network conditions change.
3Ease of manufacture
If a network without handover function (e.g., WiFi) is used, then the network access is simple, but seamless data transmission cannot be provided when network status changes
Solution Approach 1:
The patent introduces a dual-network architecture where a first network (with handover capability like 3G/LTE) and a second network (without handover like WiFi) work together. When the WiFi network cannot provide seamless transmission, the system uses the 3G/LTE network as an intermediary to maintain data flow continuity, effectively compensating for WiFi's lack of native handover functionality.
4Reliability
If multiple networks are used for data transmission, then network reliability is improved, but the complexity of managing multiple networks increases
Solution Approach 1:
The patent implements self-service mechanisms where the transmitting and receiving devices autonomously monitor network status parameters (bandwidth, delay, error rates) and make intelligent decisions about data packet routing without requiring complex external network management infrastructure. The devices automatically switch between networks based on real-time conditions, reducing management complexity while maintaining high reliability.

AI summary
A transmitting device includes: a communication unit to transmit data through two or more networks including a first network and a second network; and a transmission controller to control the communication unit to transmit the data to the receiving device through the first network, and transmit the data, which is to be transmitted to the receiving device through the first network, to the receiving device in a roundabout way through the second network in response to the data roundabout transmission request state, where the transmission controller identifies whether the receiving device is in the data roundabout transmission request state, based on at least one selected from the group consisting of an available bandwidth, a connection error generation state, a predetermined delay value of receiving the data with respect to the first network.
