5G SA Registration Anomaly Handling With Early LTE Fallback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network registration processes are time-consuming due to frequent failures caused by network anomalies or poor environmental signals, leading to delayed service resumption and poor user experience.
Innovation Solution
A method for processing network registration anomalies involves a terminal device initiating an Mth registration request to a 5G SA network after M-1 consecutive failures, using registration failure cause information and a cumulative failure count to determine if early termination conditions are met, allowing the device to stop attempting registration with the 5G SA network and switch to another network like LTE for quicker service resumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal device follows the protocol to re-attempt registration five times before falling back to LTE network, then the registration process is completed according to standard procedure, but the time affected by registration anomaly increases
Solution Approach 1:
The terminal device performs preliminary detection of registration failure cause information and cumulative failure count before completing the full registration attempt process. When anomalies are detected early, the device proactively stops further unnecessary registration attempts and triggers early fallback to LTE network, preventing time loss from continued failed attempts.
Solution Approach 2:
The patent allows the terminal device to skip the standard five-time re-attempt registration process when anomalies are detected. By evaluating failure cause information and cumulative failure count, the device can rush through the abnormal registration state and immediately fallback to LTE network, bypassing the time-consuming standard procedure.
2Adaptability or versatility
If the terminal device continuously attempts registration in 5G SA network, then the device follows protocol requirements, but user service experience deteriorates due to frequent registration failures
Solution Approach 1:
When registration anomalies are detected through failure cause information and cumulative failure count evaluation, the terminal device skips further unnecessary 5G SA registration attempts and rushes to fallback LTE network. This resolves the contradiction by prioritizing user service experience over strict protocol adherence in abnormal conditions.
Solution Approach 2:
The terminal device autonomously monitors its own registration status, evaluates failure cause information and cumulative failure count, and independently decides when to stop attempting 5G SA registration and fallback to LTE network. This self-service mechanism improves user experience without requiring external intervention while maintaining reasonable protocol compliance.

AI summary
This application provides a method for processing a network registration anomaly, an apparatus, a storage medium, and a chip, and relates to the field of communications technologies. In a 5G SA network registration process, if an anomaly occurs in a registration, a terminal device obtains registration failure cause information and a cumulative failure count, to determine whether a condition for ending the registration early is met. If the condition is met, the 5G SA network registration process is ended early, and there is no need to re-attempt for five times according to a protocol, thereby quickly falling back to an LTE network to resume services. Therefore, according to the solution of this application, an abnormal registration can be ended early and another network is registered with if an anomaly occurs in a network registration, to reduce time affected by registration anomaly, thereby solving a problem of frequent registration failures due to a network anomaly or a poor environmental signal in the network registration process, and improving user service experience.
