Chipset-Aware Network Handling of Inconsistent UE Capabilities
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Legacy UEs deployed in wireless communication networks face issues with certain functionality despite supporting it according to 3GPP specifications due to inconsistent UE capability reporting, leading to network nodes being unable to distinguish between compliant and non-compliant devices, which hinders the use of advanced features for both compliant and non-compliant UEs.
Innovation Solution
The network node receives a chipset identifier from the UE, allowing it to determine how to handle the UE based on its chipset type, overriding or adapting feature configurations based on pre-defined rules or constraints associated with the chipset type, rather than relying solely on reported UE capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the network node relies on reported UE capabilities to determine feature support, then the system operates with simple capability reporting mechanisms, but legacy UEs with inconsistent capability reporting cannot be distinguished from compliant UEs, leading to feature mismatch
Solution Approach 1:
The patent introduces an intermediary verification mechanism where the network node cross-checks reported UE capabilities against actual functionality through capability verification procedures. This intermediary step validates whether the UE truly supports the reported capabilities before allowing feature usage, thereby resolving the reliability issue without requiring changes to the basic capability reporting structure.
Solution Approach 2:
The patent implements preliminary capability verification before enabling advanced features. The network node performs capability validation and verification procedures in advance to ensure the UE actually supports the required functionality. This preliminary action prevents feature mismatch by confirming capability authenticity before feature activation, addressing the reliability concern while maintaining operational simplicity.
2Adaptability or versatility
If the network node adapts to legacy UEs with inconsistent capability reporting, then legacy UE compatibility is maintained, but advanced UEs cannot utilize all features the network can provide
Solution Approach 1:
The patent applies local quality by implementing differentiated handling strategies for different UE types. The network node identifies specific UE categories (legacy vs. advanced) and applies appropriate capability verification and feature allocation policies to each group. This allows legacy UEs to maintain compatibility with basic features while advanced UEs can access full feature sets, resolving the productivity loss without sacrificing adaptability.
Solution Approach 2:
The patent introduces dynamic feature allocation based on verified UE capabilities. Instead of static feature assignment, the system dynamically adjusts which features are enabled for each UE based on real-time capability verification results. This dynamic approach ensures legacy UEs receive appropriate basic functionality while advanced UEs can utilize the complete feature set, eliminating the productivity constraint.
3Ease of operation
If the network node cannot distinguish between compliant and non-compliant UEs, then the system maintains simple operation procedures, but feature configuration accuracy deteriorates
Solution Approach 1:
The patent implements feedback mechanisms where the network node monitors UE behavior and actual capability performance, then uses this feedback to refine capability verification decisions. The system collects feedback on whether UEs actually utilize configured features as expected, and adjusts future capability verification and feature allocation based on this feedback. This maintains operational simplicity while improving configuration accuracy through continuous learning.

AI summary
Disclosed is a method performed by a network node (130) of a wireless communication network (100). The method comprises receiving, from a User Equipment, UE (140), wirelessly connected to the network node (130), a chipset identifier indicating a type of chipset of the UE (140), determining, based on the received chipset identifier, how to handle the UE (140), and communicating with the UE (140) according to the determination. By receiving an identifier indicating the chipset type the UE (140) is built on, the network node (130) can adapt its handling of the UE depending on the chipset type.
