Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing self-organizing network (SON) technologies fail to effectively address mobility-related issues in scenarios where terminal devices have a moving speed in a vertical direction, leading to connection failures and suboptimal network performance.
Innovation Solution
A data transmission method and apparatus that enables a terminal device to send information about connection failures and vertical movement to a network device, allowing the network device to optimize network configurations and improve mobility-related issues by analyzing relative location, signal coverage, and signal strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing SON technology is used for network optimization, then general network performance can be maintained, but mobility-related issues in vertical movement scenarios cannot be effectively addressed
Solution Approach 1:
The patent introduces dynamic detection and reporting mechanisms that adapt to terminal movement characteristics. The network device dynamically determines whether to send detection indications based on terminal reports, and the terminal dynamically reports connection failure information when movement is detected. This dynamic adaptation resolves the contradiction between maintaining general network performance and addressing specific vertical movement scenarios.
Solution Approach 2:
The patent changes the parameter of network optimization from static general parameters to dynamic scenario-specific parameters. By introducing movement speed detection and connection failure information reporting, the system transforms the optimization parameters to include vertical movement characteristics, enabling the network to adapt to different movement scenarios while maintaining overall network performance.
2Reliability
If the terminal device reports connection failure information including vertical movement data, then network optimization for mobility scenarios improves, but the complexity of data transmission and processing increases
Solution Approach 1:
The patent implements preliminary action by having the terminal device detect and report movement characteristics before connection failures occur. The network device uses this advance information to proactively adjust network parameters and send detection indications, preventing optimization issues rather than reacting to failures. This reduces the need for complex post-failure analysis and data transmission.
Solution Approach 2:
The terminal device performs self-detection of movement characteristics and self-reporting of connection failure information. This self-service mechanism reduces the burden on the network device for detecting and reporting mobility-related data, simplifying the overall system architecture while improving optimization effectiveness.

AI summary
The disclosure provides a data transmission method and apparatus. The method includes: The terminal device determines first information, and sends the first information to a first network device. The first information indicates that a connection failure occurs during movement of the terminal device, and the terminal device has a moving speed in a vertical direction during the movement. The first network device is a network device to which the terminal device is reconnected after the connection failure occurs. The first network device sends second information to a second network device after receiving the first information. The second information includes at least one of a location of the first network device relative to the second network device, a first signal coverage area of the first network device in the vertical direction, signal strength of a second cell in a second time period, or the first information.
