Engineering Contradiction Analysis
1Reliability
If a terminal device sends data to a network device through multiple access networks simultaneously, then data transmission reliability is improved, but system complexity increases due to multiple data paths and coordination requirements
Solution Approach 1:
The patent segments the data transmission process into distinct phases: initial data transmission through a first access network, and subsequent data transmission through a second access network. This segmentation allows the system to manage multiple access networks separately and systematically, reducing the complexity of coordinating simultaneous transmissions while maintaining reliability through phased data delivery.
Solution Approach 2:
The terminal device performs preliminary actions by establishing a first data transmission path before setting up the second path. The network device pre-configures resources and determines data splitting ratios in advance. This preliminary setup simplifies the overall system complexity by preparing the infrastructure before actual multi-path transmission begins, making the system more manageable.
2Productivity
If data is transmitted through multiple access networks with different data rates, then transmission efficiency is improved, but data synchronization becomes more difficult
Solution Approach 1:
The network device calculates a data splitting ratio based on the different data rates of the first and second access networks. This feedback mechanism dynamically adjusts the amount of data sent through each path to ensure that both data streams arrive at the network device simultaneously, maintaining synchronization accuracy while utilizing the higher combined throughput of multiple networks.
Solution Approach 2:
The patent changes the parameter of data splitting ratio to adapt to different data rates of the access networks. By adjusting this parameter, the system optimizes data transmission efficiency across networks with different speeds while maintaining precise data synchronization at the receiving end.
3Adaptability or versatility
If the network device determines data splitting ratio dynamically, then data transmission adaptability is improved, but computational complexity increases
Solution Approach 1:
The network device dynamically changes the data splitting ratio parameter based on real-time network conditions and data rates of different access networks. This parameter adjustment provides high adaptability to varying network environments while maintaining a relatively simple computational approach by focusing on a single key parameter rather than complex multi-dimensional optimization.
