UE Capability ID Segmentation for Wireless Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently handling and updating user equipment (UE) capability information due to increasing data sizes and the need for static capability IDs, which are inconvenient when capabilities change, and unrealistic to standardize in central databases.
Innovation Solution
Divide UE capability information into data blocks with unique capability IDs, such as hash values, allowing for efficient transmission and storage, with each block having a predetermined maximum size and being transmitted separately, enabling flexible updates and reduced data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If UE capability information is transmitted in a static manner upon initial registration, then the network becomes aware of UE capabilities, but the data size of UE capabilities continues to grow and becomes inefficient for updates
Solution Approach 1:
The UE capability information is divided into multiple data blocks, where each block contains a subset of capability information. This segmentation allows the network to request and transmit only specific blocks as needed, rather than transmitting the entire capability set, thereby reducing overall data transmission volume while maintaining complete capability identification capability.
Solution Approach 2:
The patent extracts essential capability identification elements (capability IDs) from the full UE capability information and transmits only these compact identifiers to the network. The full capability details can be retrieved on-demand from the UE, allowing the network to operate with minimal data while still identifying and managing UE capabilities effectively.
2Adaptability or versatility
If capability information is updated by re-registration, then the network receives updated capabilities, but the process is inconvenient and requires full capability transmission
Solution Approach 1:
By segmenting capability information into separate data blocks, the system enables selective updating of individual blocks without requiring full re-registration. The network can request specific updated blocks, and the UE can transmit only those changes, making the update process more flexible and time-efficient while maintaining complete capability information availability.
3Reliability
If static capability IDs are allocated per vendor and model, then capability identification becomes standardized, but the solution is too static and inconvenient when part of the capability is changed
Solution Approach 1:
The patent implements a dynamic capability identification system where capability information is divided into blocks that can be independently updated. Each block can be modified and re-transmitted without changing the overall capability ID structure, allowing the system to adapt to capability changes while maintaining standardized identification. This dynamic approach replaces the static vendor-model based ID allocation with a flexible block-based system.
