Multi-SIM Interface Selector for Dynamic RF Connection Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-SIM devices lack flexibility in selecting the appropriate SIM card based on various events such as geographical location, data usage, signal quality, time, duration of usage, and network performance, leading to suboptimal wireless connections.
Innovation Solution
The system allows for the selection of subscriber identity modules (SIM) cards based on event triggers, switching between SIM cards to optimize wireless connections by using multiple SIM card interfaces with multiple RF units, verifying connectivity before selection, and considering factors like signal quality and billing cycles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single SIM card is used in multi-SIM devices, then the device structure remains simple, but the flexibility to select appropriate SIM cards based on various events is lost
Solution Approach 1:
The patent implements dynamic SIM card selection by allowing the system to switch between different SIM cards based on real-time conditions such as signal quality, data usage, geographical location, and network performance. The SIM card interface is dynamically reconfigured through event triggers that monitor these parameters and automatically switch the active SIM card to optimize connection quality and reduce costs.
2Reliability
If multiple SIM cards are always active simultaneously, then network coverage is improved, but power consumption and device complexity increase
Solution Approach 1:
The system performs preliminary actions by pre-configuring multiple SIM card interfaces and establishing event trigger conditions before actual network disconnection occurs. The system monitors signal quality, data usage, and other parameters in advance, and automatically switches SIM cards proactively when predetermined conditions are met, preventing connection failures rather than reacting to them.
Solution Approach 2:
The patent changes the operational state of SIM cards dynamically by switching between active and inactive states based on monitored parameters such as signal quality thresholds, data usage limits, time of day, and geographical location. This allows the system to maintain reliable network coverage through multiple SIM cards while consuming power efficiently by keeping only the necessary SIM cards active at any given moment.
3Ease of operation
If SIM card switching is manual, then device complexity is reduced, but user convenience and response time to network changes are degraded
Solution Approach 1:
The system provides self-service by automatically monitoring network conditions, evaluating event trigger conditions, and switching between SIM cards without requiring user intervention. The device autonomously manages SIM card selection based on predefined criteria such as signal quality, data usage patterns, billing cycle information, and geographical location, thereby maximizing user convenience while maintaining manageable complexity through automated decision-making algorithms.

AI summary
A method, an apparatus and a system for using at least one SIM card interface selector to connect a plurality of radio frequency (RF) units with a plurality of Subscriber Identification Module (SIM) card interfaces in order to establish wireless connections. The quantity of SIM card interfaces is the same as or more than quantity of RF units. Further, selection of SIM card interfaces is substantially based on geographical location, data usage, time, duration of usage, and/or billing cycle information. Further, tunnels established through the wireless connections are aggregated together to form one aggregated tunnel.
