Abstract
Future sixth-generation (6G) mobile networks are envisioned to be equipped with a diverse set of powerful, yet highly specialized, optimization experts. Such a promising vision is concurrently expected to give rise to the need for scalable mechanisms that can select, combine, and orchestrate such experts based on high-level intent and uncertainty descriptions. In this paper, we propose an agentic artificial intelligence (AI)-based network optimization framework that integrates mixture of experts (MoE) architectures with large language models (LLMs). Under the proposed framework, the employed LLM acts as a semantic gate to reason over operator objectives and dynamically compose suitable optimization agents. The proposed framework is formulated in a model-agnostic manner and bridges human-readable network intents with low-level resource allocation decisions, enabling flexible optimization across heterogeneous objectives and operating conditions. As a representative instantiation, we apply the framework to a joint communication and computing network and design a library of specialized optimization experts covering throughput, fairness, and delay-driven objectives under both regular and robust conditions. Numerical simulations demonstrate that the proposed agentic MoE framework consistently achieves near-optimal performance compared to exhaustive expert combinations while outperforming individual experts across diverse objectives, including delay minimization and throughput maximization.

| You are functioning as a gate network that receives a query from the network operator and your task is to route the question to a subset of optimization expert from a library. You have experts that can be used to resolve queries either by their own or on combinations. This depends on the query if the requested information need to be a combination of the results from several experts or one expert can fully address the query. This can be solely determined by the description of each expert area of expertise. Here is a detailed description of the available experts and their area of specialization: | |

| Interpretation | To address your query, we need to focus on minimizing the maximum delay for both communication and computing, ensuring fairness among all users. Since you are dealing with both rendering (computing) and video transmission (communication), we should consider a joint approach. Given that you want minimal latency and fairness, the experts for minimizing maximum delay under regular conditions for both communication and computing should be used. |
