摘要

在紧急情况下，确保第一响应者的无缝连接是一个关键问题，因为基础设施中断和网络拥塞可能严重阻碍通信。开放无线接入网（O-RAN）承诺在无线接入网（ran）中实现一定程度的开放性，这在这种关键条件下可能是有利的，允许增强不同运营商网络之间的集成，以缓解资源短缺。本文介绍了一种基于O-RAN的架构解决方案，它利用中立托管为RAN基础设施提供统一网关。我们的方法通过利用由中立主机管理的近实时应用程序（xApps）和非实时应用程序（rApps）的部署，促进了应急响应人员的无缝访问，并优化了指定区域内RAN和核心级别的资源分配。结果证明了O-RAN中立托管在增强第一响应者连接方面的有效性，显示了吞吐量和延迟的显着改进，特别是在灾难场景下。

Exploiting O-RAN neutral hosting for first responders connectivity in emergency scenarios

Ensuring seamless connectivity for first responders represents a critical issue in emergency scenarios, where disrupted infrastructures and network congestion can significantly hinder the communication. Open Radio Access Network (O-RAN) promises a level of openness in Radio Access Networks (RANs) that could be advantageous under such critical conditions, allowing for enhanced integration across different operators’ networks to mitigate resource scarcity. This paper introduces an architectural solution based on O-RAN that leverages neutral hosting to provide a unified gateway to RAN infrastructures. Our approach facilitates seamless access for emergency responders and optimizes the allocation of resources at both the RAN and Core levels within a specified area by exploiting the deployment of near-real-time Applications (xApps) and non-real-time Applications (rApps) managed by the neutral host. The results demonstrate the effectiveness of O-RAN neutral hosting in enhancing first responders’ connectivity, showcasing significant improvements in throughput and latency, especially under disaster scenarios.

期刊介绍： Computer and Communications networks are key infrastructures of the information society with high socio-economic value as they contribute to the correct operations of many critical services (from healthcare to finance and transportation). Internet is the core of today''s computer-communication infrastructures. This has transformed the Internet, from a robust network for data transfer between computers, to a global, content-rich, communication and information system where contents are increasingly generated by the users, and distributed according to human social relations. Next-generation network technologies, architectures and protocols are therefore required to overcome the limitations of the legacy Internet and add new capabilities and services. The future Internet should be ubiquitous, secure, resilient, and closer to human communication paradigms. Computer Communications is a peer-reviewed international journal that publishes high-quality scientific articles (both theory and practice) and survey papers covering all aspects of future computer communication networks (on all layers, except the physical layer), with a special attention to the evolution of the Internet architecture, protocols, services, and applications.
