UST helped global telco resolve integration issues with CSB, improved on-time billing by 30%

The company wanted to address the integration issues which led to service and billing issues for end-user customers. UST resolved the integration issues using custom APIs and other technologies, thus helping the global telco improve invoice harmonization by 30%.


Based in Europe, this global telecommunications company employs over 100,000 people and generates more than €30 billion in annual revenue. It provides phone services, broadband connectivity, and subscription TV services to almost 350 million customers worldwide.


Local telco service operators struggled to integrate with cloud service broker

This global telco used a cloud service broker (CSB) to streamline its multi-cloud environment. However, many of the company's in-country local service operators and independent service vendors (ISVs) struggled to integrate with the CSB. As a result, the local telco operators and ISVs couldn’t onboard services to the CSB’s platform or harmonize invoices to bill end-user customers for telco services. Facing mounting pressure to resolve the issue, the CIO and the partner management leaders needed to find a high-skilled cloud systems integration partner.


Transparent communications and custom development resolved integration issues

To understand the scope of the situation, the UST project team conducted a series of workshops with the CSB support team, local telco operators, and ISVs. With that information, the team defined and developed a library of RESTful APIs to integrate the local telco operators with the CSB. The team also used technologies from Huawei Open Cloud, Acens, and other vendors to integrate the ISVs with the CSB. These integrations resolved the issues so the local telcos and ISVs could on-board services and harmonize invoices to bill end-user customers on time.


On-time customer billing increased by 30%, and ISV support response times improved by 70%

After resolving the integration issues, on-time invoicing improved by 30%. Additionally, the mean time to respond to local service operator issues saw an impressive improvement of 70%.
