The Design of a Mobile Number Portability System on a Permissioned Private Blockchain Platform

This paper discusses the design of a mobile number portability processing system in the telecom domain with a solution proposed using permissioned private blockchain technology. As a first step, the system is designed to be managed by a neutral entity. Subsequently, the design is extended to be supported by a neutral blockchain-based platform. The Hyperledger Fabric blockchain platform is used as the framework to develop the solution. Channels are utilized for different subsets of nodes that interact with each other to enable transactions in the system. Concurrent state transition graph paths are utilized to enable faster processing in the blockchain system. The paper concludes with experimental results and possibilities for future extensions.
