Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing embedded SIM management systems face reliability, availability, and maintainability issues due to the bottleneck created by a device such as a subscription manager operated by a specific company or organization, leading to deteriorated capabilities.
Innovation Solution
An embedded SIM management system utilizing a peer-to-peer network with node devices capable of peer-to-peer communication, where an information registrant device generates and broadcasts information registration request transactions including SIM identification information and profiles, and node devices accumulate these transactions into a blockchain using a consensus building algorithm.

Engineering Contradiction Analysis
1Reliability
If embedded SIM information is managed in a device such as a subscription manager operated by a specific company or organization, then centralized control and management are achieved, but reliability, availability and maintainability are deteriorated due to bottleneck
Solution Approach 1:
The patent segments the centralized subscription manager into multiple distributed node devices that form a peer-to-peer network. Each node independently stores and validates embedded SIM information, eliminating the single-point bottleneck while maintaining systematic control through consensus mechanisms.
Solution Approach 2:
The patent transitions from a single-dimensional centralized management architecture to a multi-dimensional distributed network architecture. Information is propagated across multiple nodes in the peer-to-peer network, adding spatial distribution as a new dimension to the management system, thereby improving reliability without excessive complexity.
2Reliability
If embedded SIM information is managed in a device such as a subscription manager operated by a specific company or organization, then centralized control is achieved, but availability is deteriorated
Solution Approach 1:
The patent divides the centralized subscription manager into multiple distributed node devices operating in a peer-to-peer network. This segmentation ensures that if one node becomes unavailable, other nodes continue to provide service, thereby improving availability while distributing system complexity across multiple independent units.
Solution Approach 2:
The patent changes the operational parameters of the management system from centralized single-point control to distributed multi-point control. By modifying the architectural parameter from single-node to multi-node deployment, availability is improved through redundancy while complexity is managed through standardized node implementations.
3Reliability
If embedded SIM information is managed in a device such as a subscription manager operated by a specific company or organization, then centralized management is achieved, but maintainability is deteriorated
Solution Approach 1:
The patent segments the monolithic subscription manager into multiple independent node devices. Each node can be maintained, updated, or replaced independently without affecting the entire system, thereby improving maintainability. The peer-to-peer architecture ensures that nodes can join or leave the network dynamically, facilitating easier maintenance operations.
