Abstract
This paper proposes a trusted international settlement solution based on Cross Check of CDRs, improving the credibility and verification efficiency of international settlement, and preventing fraud and tampering. Based on the distributed settlement architecture of blockchain and cloud database, the solution confirm the CDRs of home operator, roaming operator, transit operator, third-party operator and user to form a trusted consensus. Based on smart contract reducing the duplication check of CDRs and bills, the solution improve the operational efficiency. Using cloud database and blockchain deposits technology, the solution solve the data storage capacity limitation and data tampering problem of blockchain. The solution effectively solves the problems of CDRs fraud, data tampering and disclosure, CDRs/bill duplication check in the existing international settlement service of operators. Experiment proves that the settlement efficiency of the single operator in the solution can be improved to hour level to realize the fully automation of settlement process.
