Terminal Capability Grouping Reduces Signaling Overhead
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high signaling overhead associated with terminal devices reporting capability information to network devices in communication systems, which is inefficient and consumes significant resources.
Innovation Solution
Terminal devices report identifiers of capability groups instead of individual capabilities, allowing network devices to determine supported capabilities, thereby reducing signaling overhead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If terminal devices report detailed capability information to network devices, then the network device can accurately determine supported capabilities, but the signaling overhead increases significantly
Solution Approach 1:
The patent segments capability information into individual capability elements that can be selectively reported. Instead of reporting all capabilities comprehensively, the terminal device divides capabilities into discrete reportable units, allowing the network device to request only specific capabilities needed for current operations, thereby reducing overall signaling overhead while maintaining accuracy for required capabilities.
Solution Approach 2:
The patent extracts and reports only the necessary capability information rather than complete capability sets. The network device can request specific capability subsets based on current network conditions and service requirements, extracting only the essential capability data needed, thus reducing signaling overhead while preserving measurement precision for the extracted capabilities.
2Reliability
If terminal devices report capability information frequently to ensure network has current information, then the network device can make accurate routing decisions, but the signaling overhead and resource consumption increase
Solution Approach 1:
The patent implements periodic capability reporting where the terminal device reports capability information at scheduled intervals or triggered by specific events rather than continuously. This periodic action maintains capability information currency for reliable network decisions while significantly reducing resource consumption compared to continuous reporting, as the system only transmits capability data when necessary based on predefined conditions.

AI summary
The present application provides a method for reporting capabilities and a device to reduce a signaling overhead caused by reporting capability information of a terminal device. The method includes: determining, by the terminal device, at least one capability group, which capabilities supported by a terminal device belong to; and reporting, by the terminal device, an identifier of each of the at least one capability group to a network device.
