Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data stream control is implemented in multi-connection data transmission, then data transmission efficiency is improved, but system complexity increases
Solution Approach 1:
The patent introduces a service access management node as an intermediary between the terminal and multiple access networks. This node centrally manages data stream distribution across different access networks (3GPP and non-3GPP), handling the complexity of multi-connection control while allowing terminals to communicate through standardized interfaces. The intermediary absorbs the system complexity, enabling improved data transmission efficiency without burdening the terminal or individual access networks with complex control logic.
2Productivity
If multiple access networks are used for data transmission, then throughput is improved, but control difficulty increases
Solution Approach 1:
The patent segments the data transmission system into distinct functional components: the service access management node handles control plane functions and data distribution decisions, while terminal and access networks focus on data plane operations. This segmentation allows each component to operate independently with well-defined interfaces, reducing control difficulty while enabling throughput improvement through multiple access networks. The control function is separated from the transmission function, making the system easier to manage despite using multiple networks.
3Productivity
If data distribution is optimized based on network state information, then service data throughput is improved, but information processing requirements increase
Solution Approach 1:
The service access management node performs preliminary actions by collecting network state information from multiple access networks in advance and pre-establishing data distribution policies based on current network conditions. This allows the system to proactively optimize data routing before actual data transmission occurs, reducing the need for complex real-time information processing during active transmission. The node prepares distribution decisions ahead of time, improving throughput while managing information processing requirements through advance planning.

AI summary
Provided are a data distribution method and device, and a storage medium and a system. The method may comprise: receiving an access state report sent by at least one access device, wherein the access state report comprises multiple pieces of network state information for characterizing access networks provided by the corresponding access devices; and determining, based on network state information about access networks provided by various access devices and a data stream to be transmitted, data distribution amounts corresponding to various access devices. Accordingly, multi-connection data transmission control is carried out for a data stream to be transmitted, so as to improve the throughput of service data.
