UE Capability Identifier for Signaling Overhead Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies lack an effective method to determine the capability of multimode User Equipment (UE) in wireless communication systems, leading to significant signaling overhead and increased burden on core network elements.
Innovation Solution
A method where a core network element determines a UE capability identifier based on the network mode in which the UE camps, and transmits this identifier to an access network element, allowing for efficient capability determination and configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If full capability sets are transmitted between network elements, then capability determination accuracy is improved, but signaling overhead increases
Solution Approach 1:
The patent extracts only the essential capability identifier from the full capability set and transmits it between network elements. The core network element determines the UE capability identifier based on the network mode, and only this identifier is transmitted to the access network element, rather than transmitting the complete capability set, thus reducing signaling overhead while maintaining capability determination accuracy.
Solution Approach 2:
The patent uses a simplified copy (capability identifier) of the full capability set for transmission and processing. The capability identifier serves as a representative copy that contains sufficient information for capability determination without requiring transmission of the complete capability set, thereby reducing signaling overhead.
2Measurement precision
If comprehensive capability information is processed by core network elements, then capability determination accuracy is improved, but processing burden increases
Solution Approach 1:
The patent extracts only the essential capability identifier from the comprehensive capability information and processes only this identifier in the core network element. This extraction approach maintains capability determination accuracy while significantly reducing the processing burden on core network elements.
Solution Approach 2:
The patent segments the capability information into a compact capability identifier that can be processed efficiently by the core network element. This segmentation allows the core network element to handle only the essential identifier rather than the complete capability set, reducing processing complexity.
3Loss of information
If capability identifiers are used instead of full capability sets, then signaling overhead is reduced, but capability information completeness decreases
Solution Approach 1:
The capability identifier serves multiple functions: it uniquely represents the UE's capability set, enables capability determination by the access network element, and supports network mode-based capability management. This multi-functionality allows the compact identifier to replace the full capability set without loss of essential capability information.
Solution Approach 2:
The capability identifier acts as an intermediary between the UE and the access network element, conveying essential capability information in a compact form. The core network element uses the network mode to determine the appropriate capability identifier, which then mediates the capability determination process at the access network element, maintaining information completeness while reducing signaling overhead.
Data Source
AI summary
A method for determining a capability of a UE, a device and a storage medium are provided. The method includes that: the UE transmits a network mode to a core network element, wherein the network mode is used by the core network element to determine a UE capability identifier corresponding to the network mode.
