Radio Bearer Configuration via Early Response Signaling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for configuring radio bearers in LTE systems result in long ATTACH time delays, negatively impacting user experience and operator KPIs, with no effective solutions presented for resource block configuration failures.
Innovation Solution
The method involves the NodeB transmitting a response message to the UE before completing RB configuration, allowing subsequent signaling flows to proceed in parallel, thereby reducing ATTACH time delays and improving KPIs by enabling parallel processing of RB configuration and user signaling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the NodeB waits to complete RB configuration before transmitting subsequent signaling to UE, then the RB configuration reliability is improved, but the ATTACH time delay increases
Solution Approach 1:
The NodeB transmits the response message to the UE in advance, before the RB configuration is actually completed. This preliminary action allows the UE to start processing subsequent signaling flows earlier, reducing the overall ATTACH time delay while the RB configuration continues in the background.
Solution Approach 2:
The patent introduces a dynamic state management system where the NodeB tracks the RB configuration status and implements conditional rollback mechanisms. If configuration fails, the system dynamically rolls back to maintain reliability, while the initial early transmission of response messages optimizes for speed.
2Loss of time
If the NodeB transmits response message before completing RB configuration, then the ATTACH time delay is reduced, but the risk of configuration failure increases
Solution Approach 1:
The patent implements a rollback mechanism that prepares compensatory measures in advance. If the RB configuration fails after the early response message is sent, the system can roll back the configuration state while maintaining the timing benefit, thus cushioning against the reliability risk.
Solution Approach 2:
The NodeB monitors the RB configuration status and provides feedback to determine whether to proceed with subsequent signaling or initiate a rollback. This feedback mechanism ensures that reliability is maintained by detecting configuration failures and correcting them appropriately.
3Reliability
If serial processing is used for RB configuration and user signaling, then the configuration reliability is ensured, but the processing efficiency decreases
Solution Approach 1:
The patent transforms the rigid serial processing into a dynamic hybrid approach. The response message is transmitted early to enable parallel processing of user signaling, while the RB configuration continues in the background with monitoring mechanisms to ensure reliability through conditional rollback if needed.

AI summary
Disclosed are a method and device for configuring Radio Bearer (RB), the method comprises: the NodeB receives the message from the UE, wherein the message is used for indicating the NodeB to configure the at least one RB; before the NodeB completes configuring the at least one RB, the NodeB transmits the response message in response to the message to the UE. The present invention solves the problem of the long ATTACH time delay in the related art, and in turn shortens the ATTACH time delay.
