Solution Brief: Optimizing Wholesale Intercarrier Settlement with Hyperledger Fabric Blockchain

By December 5, 2019 Publications, Resources

Telecom network operators worldwide open their networks to each other to enable their mutual customers to communicate across network boundaries. This practice, known as “Interconnect,” is being used among national and international operators for fixed, mobile, and Internet services.  Network operators cross-charge each other for the interconnect services they offer each other’s customers. It is done through invoicing/billing and settlements.

Due to the large number of network operators globally and the many-to-many relationships amongst them, the complexity and amount of cross charging and settlements data is exponential and very error-prone, causing Interconnect operations to be expensive. Typically, wholesale interconnect contributes to almost 30-40% of overall traditional telecom business for a telco, but with the declining margins, it has become essential to address the blocked revenue due to disputes and to optimize the overall cost involved in resolving these discrepancies.

To illustrate how the Linux Foundation’s Hyperledger blockchain projects can be leveraged to help Telecom operators solve the Inter-Carrier Settlement problem, the Hyperledger Telecom SIG formed a subgroup for the purpose of understanding the problem from a business and technical perspective, proposing a Solution Brief “Optimizing Wholesale Intercarrier Settlement with Hyperledger Fabric Blockchain,” and developed a Proof of Concept (PoC).  Read the blog for more background about how this came together.
