Dual SIM Wireless Device Notification Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In dual SIM wireless devices, only one SIM can be active at a time, leading to missed incoming communications on the inactive SIM, which requires manual forwarding settings and increases network load.
Innovation Solution
The wireless device establishes an internet connection with the second subscription when the first SIM is active in an ongoing communication, allowing notifications of incoming communications to the inactive SIM to be received on the active SIM, eliminating the need for forwarding functions and reducing network resource consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If manual forwarding function is set to notify users of incoming communications on inactive SIM, then user awareness of incoming communications is improved, but network load and forwarding costs increase
Solution Approach 1:
The patent extracts the notification function from the traditional forwarding mechanism. Instead of forwarding the actual communication through the network, the system extracts only the notification essence (incoming call alert) and delivers it directly to the user's device via internet connection, eliminating the need for network forwarding infrastructure
Solution Approach 2:
The patent introduces an intermediary notification mechanism that acts as a mediator between the inactive SIM's incoming communication and the user. The notification server receives communication information from the inactive SIM and relays it to the user's device through internet connection, avoiding direct network forwarding while maintaining user awareness
2Loss of information
If forwarding function is used to notify incoming communications, then communication information is delivered to user, but device complexity and manual configuration requirements increase
Solution Approach 1:
The system implements self-service by automatically establishing internet connections and sending notifications without requiring user intervention. The wireless device autonomously manages the notification process by detecting incoming communications on the inactive SIM and automatically relaying them through the internet connection to the user's device
Solution Approach 2:
The patent applies preliminary action by pre-establishing an internet connection on the active SIM before incoming communications occur on the inactive SIM. This preparatory measure ensures that the notification pathway is already in place and functional, eliminating the need for manual configuration when communications arrive

AI summary
A method and a wireless device having a first Subscriber Identity Module (SIM) of a first subscription and a second SIM of a second subscription, for handling communications. The device establishes an internet connection with the second subscription when the first SIM and the first subscription are active in an ongoing communication. A notification is then received by the device over said internet connection indicating that an incoming communication directed to the second SIM has been received by the second subscription. Thereby, a user of the device is made aware of the incoming communication without requiring a forwarding function from the second subscription to the first subscription.
