The document discusses potential use cases for blockchain technology in the telecom industry. It outlines how blockchain could help streamline internal processes like billing and number portability databases. It also describes how blockchain could solve problems with roaming charges and authentication across networks by enabling the sharing of subscriber identity and billing information in real-time on a distributed ledger. Finally, the document predicts that the use of blockchain in the telecom industry will grow significantly in the next few years and eventually become standard practice.

1. Blockchain Use Cases For Telecom Industry

2. INTRODUCTION
• Telecom industry today has the most complex operations framework, involving many
partners, vendors, customers, distributors, network providers, VAS providers.
• There are a lot of trust issues and transparency challenges due to the involvement of
multiple entities.
• Also, there are no clear mechanism to track end-to-end activities of every entity.

3. Blockchain UseCases
• Internal processes:
o The processes such as OSS (Operation Support System) and BSS processes
(Business Support System) such as billing and number portability databases can
be streamlined using blockchain.
o The interest groups can validate billing without hassle. This is possible with the
help of an intercompany blockchain shared among customers, VAS providers,
VPMN, HPMN and telecom companies.
o Also, a migrating customer can be quickly on-boarded on network after receiving
a porting request, if receiving operator shares blockchain with porting customer’s
operator.

4. • Roaming:
o Blockchain can solve the age old problem of operators to integrate high-cost
systems and provide access/authentication settings for enabling roaming calls
across networks and operators.
o Blockchain can enable complex datasets across multiple parties, in real time with
high trust and security, particularly for establishing subscriber identity.
• Smart connection:
o With the help of Blockchain, device connection can be provided to multiple local
hotspots and WIFIs based on permission and adherence to certain terms and
conditions.
o It also helps with automatic generation of billing amount and payments.

5. • Smart transactions:
o Blockchain has enabled purchasing of digital assets, including music, mobile
games, gift cards and loyalty points.
• Mobile money:
o Blockchain has enabled cost-effective international remittances across the globe
with very minimal transaction charges.
o Telecom operators can become global remittance providers.
• Identity management:
o Operators could develop identity management tool that are accessible to
organizations, devices and applications.

6. • Way Forward:
o Blockchain solutions are instrumental in enabling interoperability between
internal as well as external systems for telecom companies.
o This can bring down infrastructure as well as compliance cost, and save
operators from roaming/identity fraud.
o Telecom industry today faces the challenge of eroding margins.
o There is a high pressure to cut down the cost and at the same time adopt service
innovations.
o Blockchain is the right tool to not only bring in service efficiencies and innovation,
but also keep a check on fraudulent practices.

7. Conclusion
• The use cases above demonstrate the different ways that telecom industry can invest
in the development and implementation of blockchain-based products.
• We estimate that, within the next few years, the use of blockchain technology by the
telecommunications industry will become more prevalent.
• It will eventually become the norm.
