Access Network Device Bearer Modification Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile communications networks, the modification of radio access bearers by access network devices often conflicts with the complete registration procedure of terminal devices, leading to deadlocks and poor service experiences, especially when transitioning to 5G networks with high bandwidth and low latency requirements.
Innovation Solution
An access network device determines whether a terminal device has completed its registration procedure before modifying the radio access bearer, ensuring that the modification does not interfere with the registration process, and only proceeds after confirmation, thereby avoiding conflicts and ensuring normal service operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the access network device actively triggers modification to the radio access bearer to enable 5G high bandwidth and low latency service as soon as possible, then the service speed and quality are improved, but the complete registration procedure of the terminal device is conflicted and deadlocked occurs
Solution Approach 1:
The access network device performs preliminary action by determining whether the terminal device has completed the complete registration procedure before triggering radio access bearer modification. This preliminary check prevents the modification from interfering with the ongoing registration process, thereby avoiding deadlocks while still enabling timely 5G service deployment after registration is complete
2Reliability
If the access network device triggers modification to the radio access bearer during the complete registration procedure, then the service quality is improved, but the signaling procedure fails and service cannot be normally performed
Solution Approach 1:
The access network device performs preliminary determination of the terminal device's registration status before initiating radio access bearer modification. This ensures that modification only occurs after the complete registration procedure is successfully completed, preventing signaling failures and ensuring both service quality and procedure success
3Productivity
If the access network device modifies the radio access bearer without checking registration status, then the service deployment speed is improved, but conflicts with the complete registration procedure and causes deadlocks
Solution Approach 1:
The access network device performs preliminary determination of registration completion status before triggering radio access bearer modification. This preliminary check ensures that modification operations only occur after the terminal device has successfully completed its registration procedure, thereby preventing conflicts and deadlocks while maintaining efficient service deployment

AI summary
A bearer modification method and an access network device. The method includes determining, by an access network device, that a terminal device completes a complete registration procedure, or determining that the terminal device does not complete the complete registration procedure, and waiting for the terminal device to complete the complete registration procedure, and modifying, by the access network device, a radio access bearer of the terminal device.
