UE Direction Messaging for Clear Network Rejection Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
End-users face difficulties in understanding network rejection reasons due to unintelligible NAS cause codes, leading to frustration and complaints when their devices are continuously rejected from networks.
Innovation Solution
A method and apparatus that utilize a Short Message Service Function (SMSF) to generate and transmit clear directions via SMS to user equipment (UE) for troubleshooting, facilitated by network functions like AMF and UDM, ensuring end-users can take appropriate actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If NAS cause codes are used to indicate network rejection reasons, then network communication efficiency is improved, but user understanding of rejection reasons deteriorates
Solution Approach 1:
The patent introduces an intermediary translation mechanism that converts encoded NAS cause codes into human-readable rejection reasons. The network device receives the encoded cause code, translates it into understandable language, and sends it to the terminal device. This mediator resolves the contradiction by maintaining the efficiency of encoded communication while adding a translation layer that improves user comprehension without disrupting the underlying efficient communication protocol.
2Measurement precision
If encoded NAS cause codes are transmitted to terminals, then information transmission precision is improved, but user accessibility of the information deteriorates
Solution Approach 1:
The patent segments the information transmission process into two distinct parts: first, the precise encoded NAS cause code is transmitted for accurate technical identification, and second, a separate human-readable translation of the rejection reason is provided for user accessibility. This segmentation allows both precise information transmission and user-friendly presentation to coexist without compromising either aspect.
