Blockchain-based User Profile and Mobile Number Portability for Beyond 5G Mobile Communication Networks

Mobile Number Portability (MNP) is a regulatory requirement for Mobile Network Operators (MNO) to enable users to switch MNO. Existing centralized structures in this regard suffer from single points of failure, imposed switching costs, data leakage, low availability, and high latency. In this paper, we propose a Blockchain-based system to allow switching between MNOs while keeping users’ profiles and phone numbers. The experiments confirm that our solution can provide fast and scalable profile management and switching solutions.
