Device-Centric Roaming Payment via Blockchain
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for providing communication services to devices while roaming result in inefficiencies due to excessive communication overhead and latency, as they often require communication between the visiting network, home network, and the internet, and may not allow for direct negotiation of contracts with multiple providers.
Innovation Solution
A system and method that enables device-centric payments using blockchain technology, where the device records service usage and submits it to the visiting network, allowing for direct payment verification and reconciliation without involving the home network, thus reducing latency and communication overhead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional roaming service methods are used, then service can be provided to devices while roaming, but communication overhead and latency increase due to excessive communication between visiting network, home network, and internet
Solution Approach 1:
The patent extracts the home network from the service provision process by enabling the device to store and use local payment credentials directly at the visiting network. This eliminates the need for real-time communication with the home network during service usage, thereby reducing latency while maintaining service reliability.
Solution Approach 2:
The patent introduces a blockchain-based intermediary system that acts as a trusted mediator between the device, visiting network, and home network. The blockchain stores service usage records and payment credentials in a decentralized manner, allowing verification without direct communication between all parties, thus reducing communication overhead and latency.
2Reliability
If traditional roaming service methods are used, then service can be provided to devices while roaming, but communication overhead increases due to excessive communication between multiple networks
Solution Approach 1:
The patent extracts the payment verification function from the traditional multi-network communication architecture and relocates it to the device itself through local credential storage. This eliminates redundant communication overhead between visiting network, home network, and internet while maintaining service reliability.
Solution Approach 2:
The device performs self-service by storing payment credentials and service usage records locally, enabling it to verify payments and track usage without continuous communication with external networks. This significantly reduces communication overhead while ensuring service continuity.
3Productivity
If device stores service usage records locally, then payment verification becomes more efficient, but device complexity increases
Solution Approach 1:
The patent implements a universal blockchain-based credential storage system that can be deployed across different device types and networks. The blockchain infrastructure provides a standardized, multi-functional platform for storing payment credentials, service records, and verification data, reducing the complexity burden on individual devices while maintaining high verification efficiency.
Data Source
AI summary
A system, method, and computer program product are provided for providing device centric payments in roaming conditions. In operation, a device requests service from a visiting communication network. The device provides an identity associated with the device. The device records an amount of service utilized (e.g. utilizing blockchain technology, etc.). The device submits the amount of service utilized to the visiting network or to a blockchain, such that the visiting network is capable of determining whether the amount of service utilized recorded by the device is similar to an amount of service usage measured by the visiting network (e.g. when an established credit limit available has been utilized, etc.).
