Viettel High Tech wins Telecom Review Excellence Award in Dubai

Viettel High Tech has become the first Vietnamese enterprise to be honored at the Telecom Review Excellence Awards. The company received the “Best Technology Deployment in Asia” award at the ceremony held in Dubai, UAE.

The recognition is for the development of vOCS 4.0, a next-generation real-time Online Charging System (OCS) built on a Cloud Native architecture. This system is critical for telecommunications, managing calls, messages, data traffic, and promotional programs as they occur.

In the last three months, Viettel High Tech, in coordination with Viettel Networks and Viettel Telecom, completed the transition of over 100 million mobile subscribers in Vietnam and approximately 5,000 service packages from vOCS 3.0 to vOCS 4.0. The upgrade was performed on an active network without service disruptions. Currently, the vOCS platform serves more than 220 million subscribers across Vietnam and 10 international markets where Viettel operates.

The vOCS 4.0 system is capable of processing over 300,000 transactions per second, totaling more than 1 billion transactions per hour, with latency under 5 milliseconds. Compared to previous generations, the system reduces hardware investment costs by up to 50%, shortens deployment time by 30%, and triples the speed of adding new features.
