Terminal SN Configuration Feedback in 5G RRC Procedures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G mobile communication systems, configuring a Secondary Node (SN) during Radio Resource Control (RRC) connection establishment or resume procedures is inefficient, as existing methods lack a fast and effective way to determine if the configured SN meets the terminal's requirements.
Innovation Solution
The method involves a terminal sending RRC messages to a first node, receiving configuration information of a second node, determining if it meets the target requirements, and sending indication information if it does not, allowing the network to release and reconfigure the SN accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the network side configures a Secondary Node (SN) during RRC connection establishment or resume procedures, then the service rate demand is supported, but the configuration efficiency is low due to lack of terminal feedback on whether the configured SN meets requirements
Solution Approach 1:
The patent introduces a feedback mechanism where the terminal evaluates the configured secondary node using locally stored measurement results and sends indication information back to the network device. This feedback loop enables the network to understand whether the configured SN meets terminal requirements, thereby improving configuration efficiency while maintaining high service rates through Dual Connectivity.
2Speed
If the terminal uses locally stored measurement results to evaluate the configured secondary node, then the evaluation speed is improved, but the accuracy may be affected by the timing of measurement results
Solution Approach 1:
The patent applies preliminary action by having the terminal perform measurements and store the results before the actual SN configuration evaluation. The measurement results are prepared in advance and stored in the terminal, enabling fast evaluation when the SN configuration arrives. This approach balances speed and accuracy by performing measurements beforehand while ensuring the results are still valid for the evaluation moment.
Data Source
AI summary
Provided are an information transmission method and apparatus, and a terminal, and a network device. The method includes a terminal sending a first Radio Resource Control (RRC) message to a first node and receiving a second RRC message sent by the first node. The second RRC message carries configuration information of a second node. The method also includes the terminal determining, according to a locally stored measurement result, whether the second node meets a target requirement. The method further includes if the second node does not meet the target requirement, the terminal carrying first indication information in a third RRC message sent to the first node. The first indication information is used for indicating that the second node is not accepted by the terminal.
