5G Terminal Capability Identifier Segmentation for Software Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the 5G NR system, existing communication capability reporting methods fail to update terminal communication capabilities when software changes occur, as the capability identifier remains unchanged despite changes in communication capabilities.
Innovation Solution
A method where a terminal determines and sends a capability identifier to a network device, allowing the network to associate and update communication capabilities based on multiple identifiers, enabling timely updates even when software is refreshed or upgraded.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single capability identifier is used to represent terminal communication capability, then the capability reporting is simplified and data volume is reduced, but the capability cannot be updated when software changes occur
Solution Approach 1:
The capability identifier is segmented into multiple independent parts: terminal identifier, capability version identifier, and capability type identifier. This segmentation allows the terminal to update specific capability information (through version or type identifiers) without changing the terminal identifier, enabling flexible capability updates while maintaining a structured reporting framework
Solution Approach 2:
The capability identifier structure is made dynamic by introducing version identifiers and type identifiers that can change independently. When software is updated, the terminal can modify the version identifier or add new type identifiers to reflect changed capabilities, making the identifier system adaptable to software changes while maintaining backward compatibility
2Reliability
If capability identifier is based on IMEI components (TAC and SVN), then the identifier is stable and easy to obtain, but it cannot reflect communication capability changes after software refresh
Solution Approach 1:
A capability version identifier is introduced as an intermediary between the stable terminal identifier (IMEI components) and the variable communication capabilities. This intermediary layer allows the system to maintain stable terminal identification while accurately reflecting capability changes through version information, preventing information loss about capability evolution
Solution Approach 2:
The identifier system transitions from static IMEI components to a dynamic multi-parameter structure including terminal identifier, capability version identifier, and capability type identifier. This parameter expansion allows the system to maintain stability (through terminal identifier) while capturing capability changes (through version and type identifiers), resolving the information loss problem
3Loss of information
If terminal reports detailed communication capability parameters, then the network has complete capability information, but the data volume and reporting overhead increase significantly
Solution Approach 1:
The patent extracts only the essential capability identification elements (terminal identifier, capability version identifier, and capability type identifier) from the complete set of communication capability parameters. This extraction provides the network with sufficient information to identify and manage terminal capabilities without requiring transmission of all detailed capability parameters, thereby reducing data volume while maintaining information completeness

AI summary
Embodiments of this application provide a communication capability reporting method, a device, and a system, so that a communications device can update its own communication capability in a timely manner when the communication capability of the communications device is associated with a capability identifier of the communications device. The method includes: determining, by a first communications device, a capability identifier of the first communications device, where the capability identifier of the first communications device is one of one or more capability identifiers corresponding to the first communications device; and sending, by the first communications device, the capability identifier of the first communications device to a second communications device, where the capability identifier of the first communications device is used to determine the communication capability of the first communications device.
