RRC Reconfiguration Verification for Ignorable Failure Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The failure of Radio Resource Control (RRC) reconfiguration procedures between a base station and user equipment (UE) leads to call interruptions due to verification failures, which trigger Radio Link Failures (RLF) and subsequent RRC connection reestablishment procedures.
Innovation Solution
The electronic device performs verification processing on RRC reconfiguration messages by checking if the verification failure is ignorable, and if so, sends an RRC reconfiguration complete message without initiating RRC connection reestablishment, thereby avoiding communication interruptions.
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 due to RLF and RRC connection reestablishment
Solution Approach 1:
The patent changes the parameter of verification strictness by introducing a judgment mechanism that distinguishes between different types of verification failures. When verification fails, the system evaluates whether the failure is ignorable before triggering RLF, thereby adjusting the effective verification threshold dynamically to balance accuracy and call continuity
Solution Approach 2:
The verification process transitions from a static binary outcome (pass/fail) to a dynamic three-state system (pass/fail/ignorable). The system adapts its response based on the nature of the verification failure, allowing flexible handling that maintains call continuity while preserving necessary verification rigor
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 introduces a new parameter dimension to the verification outcome by adding an 'ignorable' state. This changes the system behavior from always triggering reestablishment to conditionally maintaining the connection, thereby reducing time loss while preserving communication reliability through selective verification enforcement
3Reliability
If the electronic device ignores verification failure, then call continuity is improved, but verification precision deteriorates
Solution Approach 1:
The patent segments the verification failure outcomes into distinct categories (ignorable failures versus critical failures). This segmentation allows the system to maintain high verification precision for critical issues while being tolerant of minor anomalies, thus preserving both call continuity and verification integrity through differentiated handling

AI summary
Embodiments of this application provide a communication method, a communication apparatus, and 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. In this way, it is avoided that a call is interrupted due to the ignorable verification processing failure item and entering of an RRC connection reestablishment procedure. The method may include: receiving, by the electronic device, a first radio resource control 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, by the electronic device, verification processing on the first RRC reconfiguration message and the first configuration item, where the verification processing includes a first verification; and sending, by the electronic device, 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.
