Bachelor Thesis: Design and Implementation of Blockchain-based Bilateral Roaming Contractsbetween Telecommunication Providers

Title:

Design and Implementation of Blockchain-based Bilateral Roaming Contractsbetween Telecommunication Providers

Description:

When roaming in mobile telecommunication networks, bilateral roaming contracts between telecommunication providers specify the individual costs for using foreign networks. Such bi- lateral contracts are negotiated between the individual partners, where the specifics are kept confidential. The actual usage of foreign networks is then recorded in the form of call detail records, where the provider is billed based on the type and amount of used resources while roaming. In the end, the customer is billed accordingly by his telecommunication provider. The roaming contracts are subject to renegotiation periodically. The current handling of the roaming process is prone to multiple issues that can be solved using Distributed Ledger Technology (DLT).
The objective of this thesis is to model bilateral roaming contracts for telecommunication providers in a secure and confidential way using DLT. The introduction presents the current state-of-the-art and identifies stakeholders with their roles. Next sections reveal known is- sues and analyse possible solutions using DLT. This thesis investigates the features of various blockchain types and provides an overview of existing production-ready blockchain implementations. Further sections present detailed implementation of a roaming contract in the form of a smart contract on a suitable blockchain and a performance analysis.
