RRC Reconfiguration Verification Handling to Avoid Call Interruption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
RRC reconfiguration failures between a base station and user equipment (UE) lead to call interruptions due to verification failures in the RRC connection reestablishment procedure, which can occur when parameters configured by the base station are not consistently verified.
Innovation Solution
The electronic device performs verification processing on RRC reconfiguration messages, determining if the verification failure is ignorable, and sends an RRC reconfiguration complete message even if verification fails, thereby avoiding unnecessary RRC connection reestablishment and maintaining communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the electronic device performs strict verification processing on RRC reconfiguration messages, then verification accuracy is improved, but call interruption occurs when verification fails
Solution Approach 1:
The patent changes the parameter of verification result handling by introducing a new state where verification failures are ignored rather than triggering RRC connection reestablishment. This allows the device to maintain call continuity while still performing verification processing, resolving the contradiction between verification accuracy and call continuity.
2Reliability
If the electronic device triggers RRC connection reestablishment upon verification failure, then communication reliability is improved, but call interruption occurs
Solution Approach 1:
The patent applies local quality by selectively ignoring verification failures only for specific parameters (first parameter and first value) while maintaining verification for other parameters. This localized approach allows the system to maintain overall communication reliability while avoiding call interruption caused by non-critical verification failures.
3Reliability
If the electronic device enters RRC connection reestablishment procedure, then connection reliability is improved, but communication interruption occurs
Solution Approach 1:
The patent extracts the problematic verification step (verifying first parameter and first value) from the mandatory RRC reconfiguration verification process. By taking out this specific verification requirement, the system avoids triggering RRC connection reestablishment and the associated communication interruption, while still performing verification on other critical parameters.

AI summary
A communication method, an electronic device, and relate to the field of communication technologies. An ignorable verification processing failure item can be automatically skipped, to complete an RRC reconfiguration procedure. The method may include: receiving, by the electronic device, a first RRC reconfiguration message, where the first RRC reconfiguration message includes a first parameter and a value of the first parameter; and the electronic device stores a first configuration item before receiving the first RRC reconfiguration message, and the first configuration item includes a second parameter and a value of the second parameter; performing, verification processing on the first RRC reconfiguration message and the first configuration item, where the verification processing includes a first verification; and sending a first RRC reconfiguration complete message when a verification failure result of the first verification is ignorable, or a process of the first verification is ignorable.
