Modem Crash Handling via Silent Restart and Connection Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In smart terminal devices, 5G modem crashes often disrupt communication connections and user experiences due to the particularities of the 5G module and network issues, leading to interruptions in calls and internet access, and frequent notification of modem crash messages affects user experience negatively.
Innovation Solution
A message processing method and apparatus that monitor the modem's running state, restart it when crashed, and maintain communication connections while prohibiting notifications of modem crash messages to users, ensuring uninterrupted service by caching data packets and maintaining call and mobile data connections until the modem is successfully restarted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the modem crash message is notified to the user, then the user is informed of the communication failure, but the user experience deteriorates due to frequent interruptions and anxiety
Solution Approach 1:
The patent converts the harmful effect of modem crash notifications into a beneficial outcome by implementing automatic restart functionality. When the modem crashes, the system automatically detects the crash, restarts the modem, and restores communication services without user intervention. This transforms the negative user experience of frequent crash notifications into a seamless automatic recovery process, maintaining user experience while ensuring communication reliability.
2Reliability
If the modem is restarted automatically when crashed, then the communication service is restored quickly, but the system complexity increases due to monitoring and restart mechanisms
Solution Approach 1:
The patent implements a self-service mechanism where the system automatically monitors modem status, detects crashes, and triggers restart operations without requiring user intervention or complex external management. The terminal device itself performs the monitoring and restart functions through integrated software modules, eliminating the need for additional external management systems and reducing overall system complexity while maintaining high reliability.
3Ease of operation
If the modem crash notification is prohibited to the user, then the user experience is maintained, but the user loses awareness of the communication failure
Solution Approach 1:
The patent introduces an intermediary automatic restart mechanism that acts as a mediator between the modem crash event and the user. Instead of directly notifying the user of the crash, the system uses the automatic restart function as an intermediary process that handles the crash silently in the background. This intermediary mechanism restores service without exposing the crash information to the user, maintaining experience continuity while implicitly informing the user through service restoration.
4Productivity
If the communication connection state is maintained during modem crash, then service interruption is avoided, but the connection state becomes inconsistent with the actual modem status
Solution Approach 1:
The patent implements preliminary action by maintaining the communication connection state as available even before the modem crash is fully processed. The system proactively keeps the connection state as available and prepares for potential crashes, allowing services to continue operating without interruption. When a crash occurs, the automatic restart mechanism activates to restore the actual connection state, ensuring that service continuity is maintained while eventually reconciling the state consistency.

AI summary
A message processing method, applied to a terminal device including a modem, includes: monitoring a running state of the modem, and restarting the modem when it is monitored that the modem crashes; and maintaining a communication connection state, and prohibiting notification of a modem crash message to a user. By maintaining a normal communication state after the modem crashes, it is ensured that the user continues to use the various services of the terminal normally to avoid the interruption of the ongoing business of the user; and the terminal resumes normal operation after the modem is restarted, and the user does not perceive that the modem has ever crashed, thereby maintaining the experience of using the terminal normally all the time.
