Terminal Configuration Indication for Signaling Overhead Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile communications networks, repeatedly sending complete configuration information to user equipment (UE) when it accesses a cell multiple times results in significant signaling overhead, even if the configuration remains unchanged.
Innovation Solution
A method where the terminal stores valid configuration information and sends indication information to the network side device, which then responds with information on whether to use the stored configuration, its number, or type, allowing the network to optimize signaling by not resending complete configurations if they are still valid.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cell sends complete configuration information to the terminal each time it accesses, then the terminal can ensure it has valid configuration information, but the signaling overhead increases significantly
Solution Approach 1:
The patent extracts only the necessary indication information from the complete configuration information. The terminal sends first indication information to indicate whether it has valid stored configuration, and the network sends back second indication information to indicate whether to use stored configuration. This extraction approach avoids transmitting the entire configuration information while still ensuring validity, thereby reducing signaling overhead.
Solution Approach 2:
The patent applies preliminary action by having the terminal store configuration information in advance during its first access to the cell. When the terminal reaccesses the same cell, it can indicate that it has valid stored configuration information, eliminating the need to receive complete configuration information again. This preliminary storage action prevents redundant signaling overhead in subsequent accesses.
2Loss of substance
If the terminal stores and reuses configuration information, then signaling overhead is reduced, but the complexity of managing configuration validity increases
Solution Approach 1:
The patent implements feedback through a two-way indication mechanism. The terminal provides first indication information to the network about whether it has valid stored configuration. The network responds with second indication information telling the terminal whether to use its stored configuration. This feedback loop automates the configuration management process, reducing the complexity of manually managing configuration validity while maintaining reliability.
3Manufacturing precision
If the network sends complete configuration information every time, then configuration accuracy is ensured, but transmission time increases
Solution Approach 1:
The patent extracts only the essential indication information needed to verify configuration validity, rather than transmitting complete configuration information. The first indication information from the terminal and the second indication information from the network contain only the necessary data to determine whether stored configuration is valid, dramatically reducing transmission time while preserving configuration accuracy.
Solution Approach 2:
The patent applies preliminary action by having the terminal store configuration information in advance. When reaccessing the cell, the terminal can immediately indicate it has valid stored configuration without waiting for the network to transmit complete configuration information again. This preliminary storage action eliminates redundant transmission time while ensuring configuration accuracy through the indication feedback mechanism.

AI summary
A configuration information obtaining method includes: in a case that the terminal stores valid first configuration information, sending first indication information to a network side device; and receiving second indication information sent by the network side device. The first indication information is used to indicate that the terminal stores the valid first configuration information. The second indication information is used to indicate at least one of: whether the terminal uses the stored first configuration information; a number corresponding to the stored first configuration information used by the terminal; or a type corresponding to the stored first configuration information used by the terminal.
