Dual-SIM Call Preference Routing for SIM-Specific Communication Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dual SIM devices lack the ability to manage call settings individually for each subscriber identity module (SIM), leading to inconsistent communication management across multiple SIMs.
Innovation Solution
A system that identifies each SIM within a dual SIM device and applies specific call settings based on user-defined preferences, allowing differentiated communication management for each SIM.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single set of call settings is applied to all SIMs in a dual SIM device, then the device complexity is reduced and ease of operation is improved, but the adaptability to different communication needs of each SIM deteriorates
Solution Approach 1:
The patent divides the unified call settings into SIM-specific call settings, allowing each SIM to have independent call management parameters. The network device receives and processes separate call settings for each SIM card, enabling differentiated control over call behaviors, scam call handling, and notification preferences for each SIM independently.
Solution Approach 2:
The patent implements different call settings for different SIMs within the same device. Each SIM can have customized call management parameters including scam call blocking, notification sounds, and call transfer settings. This allows local optimization of call handling according to the specific needs of each SIM card while maintaining a unified system architecture.
2Adaptability or versatility
If SIM-specific call settings are implemented, then the adaptability to different communication scenarios is improved, but the device complexity and network processing burden increase
Solution Approach 1:
The network device maintains a unified call settings database that can store and manage call settings for multiple SIMs across multiple user equipment devices. The same network infrastructure and processing logic are used to handle both single-SIM and dual-SIM devices, allowing the system to serve multiple functions without requiring separate specialized systems for each SIM configuration.
3Reliability
If SIM-specific call settings are implemented, then the ability to manage scam calls differently for each SIM is improved, but the network processing time and resource consumption increase
Solution Approach 1:
The patent implements preliminary configuration of SIM-specific call settings including scam call blocking lists and filtering rules before actual call events occur. The network device pre-processes and stores call settings for each SIM, so when a call event occurs, the system can quickly retrieve and apply the appropriate pre-configured settings without performing complex real-time analysis, thereby reducing call processing time while maintaining reliable scam call filtering.

AI summary
According to aspects herein, methods and systems for management of a user device operating using a dual subscriber identification module (SIM) system. Each SIM within the Dual SIM system may have particular set of call preferences. When receiving a communication, a network may access the call preferences associated with the SIM and determine how to manage the communication. An incoming call may be managed differently between the two SIMs for the user device based on user preferences. A user may input preferences for each SIM within a user preference manager.
