Blockchain in Telecom

Digital ledger technology is enabling CSPs to create and share immutable digital identities for customers by storing data securely on the blockchian. These digital identities represent a largely untapped revenue stream for the telecom industry; identity-as-a-service.

Fraud is a big problem for the telecom industry, costing billions of dollars every year. But, blockchain technology in telecom is helping providers to combat deception in two key areas, identity theft and roaming fraud. For data roaming fraud in particular, permissioned blockchains are enabling both the sharing of verifiable data between network operators, and the instantaneous settlement of roaming contracts, both of which are helping to reduce the risk of fraud.

When it comes to 5G Networks, blockchain technology is enabling providers to drive efficiency and provide a better service to customers in a number of areas. For example, the current Access Network Discovery and Selection Function System (responsible for selecting the most appropriate access network for a device), is a centralised system prone to delays and issues surrounding provisioning of networks. With a blockchain-based solution to ANDSF, smart contracts can allow for seamless provisioning between access networks for the device and end user. Plus the ability to enforce dynamic rules and contracts across provisioning networks — unlocking discounted rates or better connections.
