RCS Auto-Configuration Retry Control to Prevent SIM Blacklisting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods fail to prevent RCS auto-configuration failures and SIM blacklisting from configuration servers, leading to non-operational RCS services and user inconvenience.
Innovation Solution
A method and system using an AI model to monitor messages between a user device and a configuration server, extract a timer and rate limiting factor from failure messages, set an alarm, store configuration information in SIM memory, and send subsequent messages based on retrieved information to avoid auto-configuration failures and reduce SIM blacklisting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If RCS auto-configuration requests are sent multiple times from different devices or secondary devices, then the configuration server can provide RCS services to more devices, but the SIM gets blacklisted from the configuration server
Solution Approach 1:
The system monitors auto-configuration messages exchanged between the user device and configuration server, detects failure messages, and uses this feedback to determine when to send retry requests. This feedback mechanism prevents excessive retry attempts that would cause blacklisting while ensuring successful configuration when failures are temporary.
Solution Approach 2:
The system extracts timer values from failure messages and sets alarms in advance before the configured time elapses. This preliminary action ensures that retry requests are sent at the appropriate time rather than immediately, preventing premature retries that would trigger blacklisting while maintaining service availability.
2Productivity
If auto-configuration retry requests are sent immediately after failure, then the RCS service can be restored quickly, but the SIM gets blacklisted due to excessive requests
Solution Approach 1:
The system extracts timer values from failure messages and sets alarms in advance before the configured time elapses. This preliminary action ensures that retry requests are sent at the appropriate time rather than immediately, preventing premature retries that would trigger blacklisting while maintaining service availability.
Solution Approach 2:
The system uses periodic alarm-based retry requests instead of continuous or immediate retry attempts. By waiting for the alarm to trigger at the appropriate time interval, the system maintains productivity while avoiding excessive requests that would cause blacklisting.
3Reliability
If the system monitors and manages auto-configuration messages with timers and rate limiting, then SIM blacklisting is reduced, but the device complexity increases
Solution Approach 1:
The system automatically monitors auto-configuration messages, detects failures, extracts timer values, sets alarms, and manages retry requests without user intervention. This self-service approach handles the increased complexity internally while maintaining simple user experience and improving reliability.
Solution Approach 2:
The system introduces an intermediary monitoring and management layer between the user device and configuration server. This intermediary handles the complex message monitoring, timer extraction, alarm setting, and retry management, isolating the complexity from both the user interface and the configuration server interaction.
4Ease of operation
If RCS auto-configuration is performed without monitoring messages and managing retry attempts, then the device complexity is low, but auto-configuration failures occur frequently
Solution Approach 1:
The system automatically monitors auto-configuration messages, detects failures, extracts timer values, sets alarms, and manages retry requests without user intervention. This self-service approach handles the increased complexity internally while maintaining simple user experience and improving reliability.
Solution Approach 2:
The system monitors auto-configuration messages exchanged between the user device and configuration server, detects failure messages, and uses this feedback to determine when to send retry requests. This feedback mechanism prevents excessive retry attempts that would cause blacklisting while ensuring successful configuration when failures are temporary.

AI summary
The disclosure relates to a method for supporting rich communication service (RCS) auto-configuration failure. The method includes: monitoring a plurality of messages exchanged between a user device and a configuration server, detecting a first message received from the configuration server is a failure message, extracting a timer from header of the failure message and a rate limiting factor of service provider from one or more databases, setting an alarm in the user device for sending a second message to the configuration server, storing configuration information including the timer and the rate limiting factor into a SIM memory, retrieving the stored configuration information from the SIM memory with reference to a requesting mode, and configuring the user device to send a third message to the configuration server based on the retrieved configuration information.
