Dual-SIM Cross-Diverter Automatic Call Forwarding Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dual-SIM, dual-standby devices require extensive user intervention to configure and manage cross-divert functionality, which is cumbersome and requires knowledge of wireless communication settings.
Innovation Solution
A method and apparatus for a dual-SIM, dual-standby device that allows automatic switching into and out of cross-divert mode through a toggle control on the user interface, activating and deactivating Call Forward Not Reachable services and call waiting without manual configuration, using phone numbers associated with each subscription.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual configuration of Call Forward Not Reachable and call waiting services is implemented, then cross-divert functionality can be achieved, but user intervention and complexity increase significantly
Solution Approach 1:
The system automatically manages Call Forward Not Reachable and call waiting services without requiring user configuration. The processor detects when a first subscription is in an active session and automatically activates cross-divert functionality for the second subscription, eliminating the need for manual CFNRc and call waiting setup that previously burdened users
Solution Approach 2:
The system pre-configures cross-divert settings by automatically activating Call Forward Not Reachable services and call waiting in advance when needed. Rather than requiring users to manually configure these services beforehand, the system proactively sets up the necessary call forwarding parameters and service states based on detected subscription activity
2Adaptability or versatility
If manual activation of Call Forward Not Reachable and call waiting services is required, then cross-divert mode can be implemented, but configuration time and user knowledge requirements increase
Solution Approach 1:
The processor automatically activates and deactivates Call Forward Not Reachable services and call waiting based on real-time detection of active sessions on the first subscription. This self-managing approach eliminates the time users would otherwise spend manually configuring each service parameter and switching modes
Solution Approach 2:
The cross-divert functionality dynamically adapts to the operational state of subscriptions. The system automatically adjusts service activation states based on whether the first subscription is in an active data or voice session, allowing the configuration to change in real-time without user intervention rather than requiring static manual setup
3Device complexity
If a single transceiver is used for multiple subscriptions, then device complexity is reduced, but the ability to communicate on multiple subscriptions simultaneously is limited
Solution Approach 1:
The single transceiver alternates between subscriptions by periodically tuning to different frequencies and networks. The system manages time-division multiplexing where the transceiver switches between first and second subscriptions at scheduled intervals, allowing communication on both subscriptions sequentially rather than requiring simultaneous multi-radio capability
Solution Approach 2:
The processor acts as an intermediary that manages the single transceiver's time-division operation between multiple subscriptions. By coordinating transceiver switching and managing call state information, the processor enables the single hardware resource to effectively serve multiple communication roles, bridging the gap between limited hardware and multiple subscription requirements

AI summary
Presented herein are methods and apparatuses for improved control of cross divert functionality in dual-SIM dual-standby (DSDS) wireless devices. According to example methods and apparatuses presented herein, a dual-SIM dual-standby device may receive a command to exit cross-divert mode, obtain a first phone number associated with a first subscription on the DSDS device and a second phone number associated with a second subscription on the DSDS device as a result of receiving the command, enable and/or disable Call Forward Not Reachable services for both the first subscription and the second subscription, activate and/or deactivate call waiting services associated with each of the first subscription and the second subscription, and forward a call from one subscription to another subscription of the DSDS device. As such, less user-intensive control of cross divert in DSDS devices is attainable.
