Thailand’s largest telecom group embarked on a strategic transformation to solidify its position as the premier telecom provider in the country. With over 50 million subscribers combined, the company aimed to enhance its service offerings and ensure long-term scalability, security, and reliability. Through a strategic partnership with Wavenet, the telecom group is modernizing its infrastructure, optimizing its service management, and enhancing its ability to deliver exceptional customer experiences.
The merger of the telecom group’s subscriber base created both exciting opportunities and significant challenges. One of the key hurdles was the integration of diverse Value-Added Services (VAS) and the modernization of their call flow systems. These VAS systems were fragmented, with varying deployment methods like disparate USSD systems and capacity limitations, particularly concerning high transaction volumes. The company faced the challenge of unifying these systems without compromising service quality or operational efficiency.
Additionally, the billing system required continuous modernization to handle complex data synchronization between new and legacy systems, ensuring smooth financial transactions for a growing customer base. With an increasing reliance on digital platforms, security concerns also arose, particularly for essential services such as USSD-based financial transactions.
The partnership between the telecom group and Wavenet focused on a comprehensive telecom integration strategy, which addressed these issues through several key initiatives:
Wavenet’s expertise enabled a smooth migration to a unified Value-Added Services (VAS) platform, optimizing service management for increased scalability. The transition allowed the telecom group to meet the growing demands of its large subscriber base by enhancing agility and enabling on-demand customer engagement via popular platforms like WhatsApp and Meta. This unified VAS solution, combined with Wavenet’s IVR consolidation capabilities, not only improved customer satisfaction but also streamlined operations, reducing costs associated with disparate systems and enhancing overall efficiency.
The continuous upgrade of the Huawei Convergent Billing System (CBS) with Wavenet’s support ensured smooth synchronization between legacy and new systems. By integrating advanced protocol-bridging middleware as part of the telecom integration layer, Wavenet helped the telecom group maintain operational integrity while evolving the system to handle an increasing volume of transactions without disruption.
To enhance service reliability and transaction security, the telecom group worked with Wavenet to upgrade its DRA system. This was particularly important for USSD-based financial services, where secure transactions are critical. Advanced encryption was incorporated to safeguard high-value financial transactions, ensuring that the telecom group could manage growing transaction volumes while maintaining trust and security in its services.
The adoption of Kubernetes by the telecom group provided the backbone for a secure and resilient telecom infrastructure. This agile, containerized approach optimized the company’s systems, enhanced continuous integration and delivery (CI/CD) processes, and improved operational resilience. Wavenet’s expertise ensured that the telecom group’s infrastructure remained robust, scalable, and capable of meeting the demands of modern telecom services.
Through this strategic partnership, the telecom group has successfully transformed its infrastructure to support a digital-first future. The key results of this collaboration include:
Wavenet’s continuous support enables the telecom group to remain at the forefront of innovation, enhancing the overall customer and developer experience. With the infrastructure now future-proofed, the telecom group is well-positioned to embrace further advancements in telecom services, ensuring continued growth and leadership in the Thai market.
This case study highlights how the telecom group, through its collaboration with Wavenet, is setting new standards for telecommunications infrastructure resilience, scalability, and security in Thailand. With a focus on telecom integration layers, Wavenet IVR consolidation, and unified value-added services, the telecom group is poised for continued success in an ever-evolving digital landscape.
