鑒於國際通訊技術的日益發展，5G技術帶來了更高速度、更低延遲和更大頻寬的應用，行動通訊服務從基本通訊發展到多種新形態應用。5G專網的價值在於其廣泛的垂直應用，不僅提高效率，還創造了新機會。然而企業對於這項新技術較為陌生，缺乏選擇適用專網部署架構的明確指引。因此，本研究旨在探討垂直場域中部署5G專網的考量因素，並制定評估準則，幫助企業做出明智的決策。
本研究採用文獻分析法和比較研究法，歸納出影響專網建置的各種因素。5G專網架構類型主要分為獨立專網（Standalone Non-Public Network, SNPN）和公網整合專網（Public Network Integrated Non-Public Network, PNI-NPN），針對不同專網架構，總結出各種5G專網部署模式的優勢和風險。評估準則旨在提供垂直應用場域業者引進企業專網時能有一個明確的指引，引導企業根據其本身的需求與資源，從財務、技術、營運及政策與法規四個層面進行評估，供企業在建制專網前能有更全面性的衡量，找到最適合的架構模式。
研究發現，不同架構適用於不同應用場景。獨立專網提供最高的控制和安全性，適合需要高度自主性和隱私保護的大型企業。共組核網在成本效益和技術支援方面具有優勢，適合中小企業。網路切片技術提供快速部署和高靈活性的解決方案，適合科技初創公司和短期活動。
綜上所述，本研究希望這些結果能為企業在選擇5G專網架構時提供參考，幫助其實現5G專網的最大化效益。根據企業自身的業務需求和資源狀況，做出最適合的決策，以在激烈的市場競爭中取得優勢。

5G technology, with its higher speeds, lower latency, and greater bandwidth, has revolutionized mobile communication services, offering diverse new applications. Despite its benefits, enterprises often lack clear guidance on selecting the right 5G non-public network architecture. This study explores the considerations for deploying 5G non-public networks in various fields and establishes evaluation criteria to assist in decision-making.
Through literature analysis and comparative research, the study identifies key factors influencing non-public network construction. It categorizes 5G private architectures into Standalone Non-Public Networks (SNPN) and Public Network Integrated Non-Public Networks (PNI-NPN), outlining the advantages and risks of each. The evaluation criteria guide enterprises to assess financial, technical, operational, and regulatory aspects, helping them choose the most suitable architecture.
Findings suggest that standalone networks provide high control and security for large enterprises, while integrated networks offer cost-effectiveness and support for small and medium-sized enterprises. Network slicing technology suits startups and short-term projects due to its fast deployment and flexibility.
This study aims to help enterprises select the best 5G non-public network architecture to maximize benefits and gain a competitive edge based on their needs and resources.
