Independent Communication Processor Restart for SIM Registration Failure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for restarting communication after a SIM card registration failure require powering off and restarting the entire smartphone, which is time-consuming and disrupts user experience, especially with multiple application programs running.
Innovation Solution
A method and apparatus that allow the communication processor to be restarted independently without restarting the application processor, enabling the SIM card to re-register with the network by acquiring failure information, displaying prompts to the user, and receiving confirmation to initiate the restart process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the entire smartphone is powered off and restarted to re-register the SIM card, then the SIM card can be re-registered with the network, but the restart process takes a long time and disrupts user experience
Solution Approach 1:
The smartphone system is segmented into two independent processors: the application processor (handling user applications) and the communication processor (handling network communication). When SIM card registration fails, only the communication processor is restarted, while the application processor continues running without interruption. This segmentation allows the system to restart only the necessary component rather than the entire device, significantly reducing restart time and preserving user experience.
2Reliability
If the entire smartphone is restarted to re-register the SIM card, then network connection is restored, but ongoing application processes are interrupted
Solution Approach 1:
The system architecture divides functionality into separate processors: the application processor maintains user applications and their running states, while the communication processor handles network operations. This segmentation enables independent restarting of the communication processor without affecting application processes, thus maintaining ease of operation and user experience while restoring network connection.
Solution Approach 2:
The communication processor acts as an intermediary between the application processor and the network. When network registration fails, the communication processor can be restarted to re-establish network connectivity, while the application processor continues to run applications. This intermediary role allows network issues to be resolved without disrupting user applications.
3Reliability
If a full machine restart is performed to restore SIM card registration, then communication function is restored, but the process is complex and time-consuming
Solution Approach 1:
The dual-processor architecture segments the restart process into a simplified operation: only the communication processor needs to be restarted for SIM card registration issues, eliminating the complexity of a full system restart. This segmentation reduces the restart process from a complex full-system operation to a simple component-level operation.

AI summary
Disclosed in the present invention are a method and an apparatus for restarting communication after registration of a subscriber identity module SIM card fails, which belongs to the field of mobile communications. The method includes: acquiring failure information about registration of the SIM card; displaying the failure information and prompt information on an interface, and receiving confirmation information that is replied by a user according to the prompt information; and restarting, according to the confirmation information, a communication processor under the condition of not turning off an application processor or not restarting the application processor, so as to re-register the SIM card.
