Multi-SIM Application Line Selection for Secure Enterprise Communications
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
DSDS devices lack the ability to distinguish which line of service should be used for specific types of user profiles or communications, posing a challenge for enterprises that require secure data transmission.
Innovation Solution
Systems and methods enable applications to be assigned to specific lines of service at the user or telephony manager level without separate mobile device management software, allowing users or administrators to designate applications to use a designated line on DSDS devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If DSDS devices support multiple lines of service simultaneously, then the device versatility and user flexibility are improved, but the ability to distinguish and secure specific lines for enterprise communications deteriorates
Solution Approach 1:
The patent segments the line selection process by introducing application-specific line designation. Each application can be independently assigned to a specific line of service, allowing enterprise applications to be routed to secure lines while personal applications use other lines. This segmentation resolves the contradiction by maintaining multi-line support while enabling precise line distinction for different application types.
Solution Approach 2:
The patent applies local quality by allowing different line selection policies for different applications. Instead of a uniform line selection approach, the system enables administrators or users to specify which line should be used for particular applications (e.g., enterprise email uses Line 1, personal browsing uses Line 2). This localized control ensures enterprise communications are securely routed while maintaining overall device versatility.
2Ease of operation
If automatic line selection is implemented for applications, then the ease of operation is improved, but the control over secure data transmission deteriorates
Solution Approach 1:
The patent implements preliminary action by pre-configuring line associations for applications during device setup or through administrator policy deployment. The system proactively establishes which applications should use which lines before actual communication occurs. This preliminary configuration maintains ease of operation through automatic selection while ensuring secure transmission control is embedded in advance for enterprise applications.
Solution Approach 2:
The system incorporates feedback mechanisms where the device monitors which applications are running and automatically applies the appropriate line selection rules. The feedback loop ensures that enterprise applications are consistently routed to secure lines while maintaining automatic operation. The system continuously adapts line selection based on active application states, preserving both automation and security control.
3Reliability
If separate mobile device management software is used to assign lines to applications, then the security control is improved, but the device complexity deteriorates
Solution Approach 1:
The patent merges the line selection functionality directly into the operating system's telephony manager or application framework, eliminating the need for separate mobile device management software. The line assignment capability is integrated into the existing application launch and network connection infrastructure. This integration maintains security control through systematic line assignment while reducing device complexity by removing redundant software layers.
Solution Approach 2:
The patent makes the telephony manager or application framework multi-functional by adding line selection capabilities to existing system components. The same system that manages application execution and network connections now also handles line assignment. This universal approach provides security control through a unified system while avoiding the complexity of separate specialized software, as the existing infrastructure performs multiple functions including line management.
Data Source
AI summary
Systems and methods described herein enable association of an application with a line of service on Dual SIM Dual Standby (DSDS) devices. A user equipment (UE) device receives a command to execute an application that requires a mobile network connection. The UE device detects multiple available subscriber identity modules (SIMs), wherein each of the multiple available SIMs is associated with a different line of service. The UE device extracts an application identifier for the application, and determines, based on the application identifier, that the application is associated with a designated line of service. The UE devices initiates a session connection request for the application using a SIM, of the multiple available SIMs, associated with the designated line of service.
