AI Agents transforming telecom: Efficiency, experience, and beyond. Welcome to join us at C12 booth in Hall 3 for details! CSPs face growing challenges in driving business growth while managing increasingly complex operations. Current siloed AI deployments limit efficiency, hinder ROI assessment, and create barriers to staff engagement with AI. The rise of Large Language Models (LLMs) and AI agents presents a transformative opportunity to address these challenges. However, they also present unique technical obstacles, such as reconciling the deterministic requirements of applications with the inherent uncertainty of LLM outputs, enhancing LLMs' accuracy in complex task planning, and improving their ability to continuously reflect and adapt during execution. Participating operators and vendors have reached an industry consensus that LLM-based AI agents are the key to tackling these issues. They also point out that operators need a systematic approach to guide the application of this advanced technology in production to achieve goals such as improving operational efficiency, enhancing customer experience, and exploring rapidly evolving demands, ultimately reaching a new level of autonomous operations. This innovative project pioneers the introduction of an LLM-based AI agent implementation framework and technical architecture, promoting the seamless integration of LLMs and AI agents with telecom operator processes. The implementation framework includes the VOF value model and execution system, adhering to industry standards such as ODA, AIOps, DT4DI, and AOMM, ensuring scalability and adaptability in telecom business cases. The technical architecture applies the operator's digital twins and domain knowledge to large model training. The framework proposes the use of engineering methods to effectively reduce AI agent hallucination and lower the threshold for business personnel to write agents, greatly improving the reliability and usability of AI agents and making them applicable to multiple value streams in telecom operations, maintenance, and customer experience management. In this project, China Telecom and HKT conducted pilots in areas such as broadband home self-service, customer complaint handling, and VVIP user experience assurance, achieving tangible results in operational efficiency improvement, operational cost savings, and customer satisfaction enhancement. Operators plan to extend the solution to support a wider range of areas, including new business development, stable and secure operations, operational efficiency improvement, and green energy-saving initiatives. This project sets a new benchmark for best practices for other telecom operators and vendors. Furthermore, participants are actively collaborating to participate in TM Forum standard construction, promoting broader industry cooperation and encouraging more partners to embark on this transformative journey together.
