The new 5G networks must face the challenge to fulfill multiple requirements in different use cases, applications and verticals. These networks are designed to provide strict Quality of Service (QoS) compliance independently of the network conditions in each use case. Some use cases are deployed in Public Land Mobile Network (PLMN), infrastructures that are managed by mobile network operators. However, for other use cases, devices are connected to services in private networks named Non-Public Networks (NPNs). Network slicing is the 5G concept that addresses the compliance of multiple services requirements on the same network by virtualizing the physical network infrastructure. Network Slices (NSs) are created to manage the different requirements above and to ensure coexistence between these different requirements. In this work, we avail from network slicing concept to create a solution for NPNs in e-health environments which maintains QoS and privacy requirements among slices. Moreover, we also propose a blockchain mechanism to secure the NS management layer. This mechanism ensures data integrity and reliability for the NSs settings. We validate our approach by demonstrating our comprehensive solution to secure e-health environments sensitive data and the management of the slices by the e-health environments. We deployed a Proof of Concept (PoC) using the 5G EmPOWER system and a public blockchain and we evaluate some performance metrics in different scenarios.

在电子医疗环境中使用区块链进行分布式网络切片管理

新的5G网络必须面对挑战,以在不同的用例,应用程序和垂直领域满足多种要求。这些网络旨在提供严格的服务质量(QoS)合规性,而与每种用例中的网络条件无关。一些用例部署在公共陆地移动网络(PLMN)中,该公共基础设施由移动网络运营商管理。但是,对于其他用例,设备连接到名为非公共网络(NPN)的专用网络中的服务。网络切片是5G概念,它通过虚拟化物理网络基础架构来满足同一网络上多种服务要求的合规性。创建网络切片(NS)来管理上述不同需求,并确保这些不同需求之间的共存。在这项工作中,我们从网络切片概念出发,为电子医疗环境中的NPN创建一个解决方案,该解决方案可维持切片之间的QoS和隐私要求。此外,我们还提出了一种区块链机制来保护NS管理层。此机制可确保NSs设置的数据完整性和可靠性。我们通过展示我们的综合解决方案来验证我们的方法,该解决方案可保护电子卫生环境敏感数据以及电子卫生环境对切片的管理。我们使用5G EmPOWER系统和公共区块链部署了概念验证(PoC),并在不同情况下评估了一些性能指标。此机制可确保NSs设置的数据完整性和可靠性。我们通过展示我们的综合解决方案来验证我们的方法,该解决方案可保护电子卫生环境敏感数据以及电子卫生环境对切片的管理。我们使用5G EmPOWER系统和公共区块链部署了概念验证(PoC),并在不同情况下评估了一些性能指标。此机制可确保NSs设置的数据完整性和可靠性。我们通过展示我们的综合解决方案来验证我们的方法,该解决方案可保护电子卫生环境敏感数据以及电子卫生环境对切片的管理。我们使用5G EmPOWER系统和公共区块链部署了概念验证(PoC),并在不同情况下评估了一些性能指标。
