Engineering Contradiction Analysis
1Productivity
If direct connection communication is established between two UEs based on physical layer conditions, then data transmission efficiency is improved, but trust and security problems arise due to lack of authentication mechanisms
Solution Approach 1:
The patent introduces a base station as an intermediary that performs authentication and authorization for direct connection communications between UEs. The base station verifies the trust relationships and security credentials before allowing direct connections, thus maintaining security while enabling efficient peer-to-peer data transmission.
Solution Approach 2:
The patent implements preliminary authentication and trust verification procedures before establishing direct connections. The base station pre-authenticates UEs and establishes trust relationships in advance, so that when direct connections are needed, the security framework is already in place, enabling both efficiency and reliability.
2Loss of energy
If direct connection communication is established without network side intervention, then network load is reduced, but excitation and resource allocation problems occur
Solution Approach 1:
The patent applies partial network intervention where the base station handles only critical functions like authentication, authorization, and excitation management, while allowing UEs to autonomously establish and manage the actual data transmission connections. This reduces overall network load while maintaining necessary control functions.
Solution Approach 2:
The patent enables UEs to autonomously establish direct connections and manage their own data transmission after receiving initial authorization from the base station. The UEs self-configure their direct links and handle resource allocation locally, reducing the need for continuous network intervention while ensuring initial proper setup through base station coordination.

AI summary
A data transmission method and a data transmission system are provided. The data transmission method includes: judging whether to adopt a data transmission mode of a direct connection communication according to a service request received by a network side or triggered by the network side; determining a data source node and a data reception target node corresponding to the service request when a judgment result is to adopt the data transmission mode of the direct connection communication; selecting a bearer network node corresponding to the data source node and the data reception target node according to a physical domain network selection principle and a business mode domain network selection principle; and determining a network structure corresponding to the data transmission mode of the direct connection communication according to the bearer network node, the data source node and the data reception target node. Therefore, an optimized direct connection communication network model can be established so as to solve a trust problem and an excitation problem in a direct connection communication network.
