AI Technical Summary
Technical Problem
In inter-carrier roaming, the existing hop-by-hop method cannot effectively detect and prevent relay operators from tampering with signals during roaming, resulting in insufficient communication security.
Method used
By receiving and sending signals in network nodes, relevant information is written into the blockchain and signal log database, enabling the traceability and immutability of signals. Blockchain and database technologies are used to ensure the reliability and security of communication.
Benefits of technology
It improves communication security in service-based architecture (SBA), enabling technical verification of roaming relay operator behavior and ensuring the reliability and security of communication.

Abstract
A network node has a reception section that receives a signal, a transmission section that transmits the signal, and a control section that writes information about the signal in a blockchain and writes a log of the signal in a database.
