NR Registration Retry Control Across Tracking Areas
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In scenarios of NR network congestion, terminals repeatedly initiate invalid network registration requests due to tracking area changes, leading to poor network reliability and disrupted user communication.
Innovation Solution
Implement a network registration method that includes starting a registration timer and limiting attempts, retransmitting NR requests upon timer expiry, and stopping attempts when entering forbidden tracking areas, switching to LTE networks if necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the terminal repeatedly initiates NR network registration requests when entering new tracking areas, then the terminal can attempt to access the network in different areas, but the registration request count is continuously reset and invalid requests are generated, leading to poor network reliability
Solution Approach 1:
The patent applies preliminary action by establishing a forbidden list of tracking areas before the terminal attempts registration. When the terminal enters a tracking area that is already in the forbidden list, it proactively avoids initiating registration requests. This prevents the waste of repeatedly attempting registration in areas known to have registration failures, thereby improving network connection reliability while maintaining adaptability to different tracking areas.
2Productivity
If the terminal continues to attempt registration in tracking areas with failed registration, then the terminal can try to establish connection, but it wastes time and resources on invalid requests, affecting normal user communication
Solution Approach 1:
The patent implements feedback by monitoring registration request outcomes and using this information to update the forbidden list. When registration attempts fail in a tracking area, the system feeds back this failure information by adding the tracking area to the forbidden list. This feedback mechanism enables the terminal to learn from past registration failures and avoid repeating them, thereby improving registration efficiency and reducing time loss from invalid attempts.
3Adaptability or versatility
If the registration request count is reset when entering new tracking areas, then the terminal can attempt registration in each new area, but this prevents the count from reaching the limited number of attempts and causes continuous invalid requests
Solution Approach 1:
The patent applies preliminary action by pre-establishing the forbidden list of tracking areas before registration attempts are made. When the terminal enters a new tracking area, it first checks whether the area exists in the forbidden list. If it does, the terminal proactively avoids registration attempts. This preliminary check prevents the registration request count from being continuously reset and reused for invalid requests, thereby improving network access reliability while preserving the terminal's ability to adapt to new tracking areas.

AI summary
A network registration method and apparatus, and a storage medium and an electronic device, which relate to the technical field of communications. The method comprises: in response to entering a SGMM-deregistered.attempting-registration state, starting a registration timer and limiting the number of registration attempts; after a timeout of the registration timer, re-transmitting an NR network registration request; and if an entered new tracking area is in a prohibition list, stopping the re-transmission. By means of the method, a terminal can be prevented from repeatedly initiating invalid network registration requests.
