Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is transmitted through a single channel in 3G network, then the transmission path is simple, but the bandwidth is limited and stability is poor
Solution Approach 1:
The patent segments the data transmission into multiple parallel channels (M channels) between the 3G AE and 3G RE. Each channel can independently transmit data packets, allowing the system to achieve load balancing and failover capabilities. This segmentation resolves the contradiction by distributing the transmission load across multiple paths, improving reliability without requiring a single complex transmission system.
Solution Approach 2:
The patent introduces a multi-dimensional transmission architecture by adding multiple parallel channels (M channels) between the access endpoint and relay endpoint. This dimensional expansion from single-channel to multi-channel transmission enables the system to overcome the bandwidth and stability limitations of 3G networks while maintaining protocol simplicity through standardized PDU handling.
2Productivity
If conventional TCP/UDP protocols are used, then the software construction is simple, but the transmission quality cannot be optimized for 3G network conditions
Solution Approach 1:
The patent introduces 3G AE (Access Endpoint) and 3G RE (Relay Endpoint) as intermediary components between the sender and receiver. These intermediaries specialize in optimizing data transmission for 3G network conditions by implementing multi-channel encoding, packet reassembly, and quality adjustment. This intermediary approach allows conventional TCP/UDP protocols to achieve enhanced performance without requiring fundamental protocol changes.
Solution Approach 2:
The patent changes the transmission parameters by introducing M channels for parallel data transmission and using N PDUs (protocol data units) for packetization. These parameter changes enable the system to adapt to 3G network conditions by adjusting the number of active channels and packet sizes dynamically, thereby improving transmission quality while maintaining protocol compatibility.
3Adaptability or versatility
If audio-visual data is transmitted in real time through 3G network, then the service coverage is extended, but the data experiences delay and packet loss
Solution Approach 1:
The patent segments the audio-visual data stream into multiple smaller packets (N PDUs) that can be transmitted simultaneously through M parallel channels. This segmentation allows critical audio-visual data to be distributed across multiple paths, reducing the impact of packet loss and minimizing delay while maintaining real-time service coverage extension.
Solution Approach 2:
The patent implements beforehand cushioning by establishing M backup channels between the 3G AE and 3G RE before data transmission begins. These pre-configured channels serve as redundancy that can activate immediately when packet loss or delay is detected, cushioning the impact of unstable 3G network conditions and ensuring continuous reliable transmission.
Data Source
AI summary
A data transmission method and apparatus are disclosed. A 3G AE and a 3G RE are deployed between a sender device and a receiver device, M channels are established between the 3G AE and the 3G RE, and M is larger than or equal to 2. The method includes that, the 3G AE encapsulates data sent by the sender device into N PDUs, and transmits the N PDUs to the 3G RE through the M channels between the 3G AE and the 3G RE; and the 3G RE restores the received PDUs to the data sent by the sender device, and sends the data to the receiver device; where N is larger than or equal to 2, and equal to or different from M.
