Virtual SIM Bonding for Multi-Modem Bandwidth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems often face limitations in bandwidth, mobility, territorial coverage, and uplink capacity, particularly in cellular networks, as they require multiple SIMs for channel bonding, which can be costly and inefficient in terms of resource utilization.
Innovation Solution
The implementation of a system that utilizes virtual SIMs (VSIMs) to manage multiple wireless modems, allowing for the selection and optimization of virtual identities based on performance and cost criteria, enabling simultaneous data transmission over multiple wireless channels without the need for physical SIMs in each device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple physical SIMs are used for channel bonding to achieve sufficient bandwidth and uplink capacity, then communication performance is improved, but device complexity and cost increase
Solution Approach 1:
The patent uses virtual SIMs (VSIMs) as software-based copies of physical SIM functionality. Instead of requiring multiple physical SIM cards, the system creates virtual representations of SIM identities that can be loaded into modems through software, thereby achieving multi-channel bonding without the physical hardware overhead
Solution Approach 2:
The patent replaces the mechanical/physical SIM card insertion system with a software-based virtual identity loading mechanism. The bonding manager dynamically loads virtual SIM identities into modems via software commands, eliminating the need for physical SIM trays, cards, and associated mechanical interfaces
2Productivity
If multiple physical SIMs are used for channel bonding to achieve sufficient uplink capacity, then communication performance is improved, but cost increases
Solution Approach 1:
The patent creates virtual copies of SIM identities that can be reused across multiple modems and devices. A single physical SIM's identity can be virtualized and distributed to multiple modems, eliminating the need to purchase multiple expensive physical SIM cards for channel bonding operations
Solution Approach 2:
The virtual SIM system allows a single SIM identity to serve multiple functions simultaneously across different modems and devices. The same virtual identity can be loaded into multiple modems for channel bonding, providing universal reuse of subscription credentials and reducing overall system cost
3Productivity
If multiple physical SIMs are used for channel bonding to achieve full territorial coverage, then communication performance is improved, but ease of operation deteriorates
Solution Approach 1:
The patent implements dynamic selection and loading of virtual SIM identities based on real-time network conditions and location. The bonding manager automatically chooses appropriate virtual SIMs from available options, dynamically adapting to territorial coverage requirements without manual user intervention
Solution Approach 2:
The system performs self-service by automatically selecting and loading the appropriate virtual SIM identities needed for channel bonding based on current network conditions. The bonding manager autonomously manages the virtual SIM pool and allocates identities without requiring user configuration or physical SIM manipulation

AI summary
Communication apparatus includes an interface to a plurality of wireless modems and bonding circuitry, which is configured to receive multiple virtual identities in the apparatus, to load respective ones of the received virtual identities into one or more of the wireless modems, and to communicate over the air by simultaneously transmitting or receiving a data stream over at least the two or more of the wireless modems. Systems and methods for such communication are provided, as well.
