Fifth-Generation (5G) mobile networks are expected to perform according to the stringent performance targets assigned by standardization committees. Therefore, significant changes are proposed to the network infrastructure to achieve the expected performance levels. Network Function Virtualization, cloud computing and Software Defined Networks are some of the main technologies being utilised to ensure network design, with optimum performance and efficient resource utilization. The aforementioned technologies are shifting the network architecture into service-based rather device-based architecture. In this regard, we introduce Media Casting as a service (MCaaS) and IoRL-Cache service (IoRL-C). The former is a service that proposed as an integration solution between the broadcasting industry and Mobile Network Operators, while the latter proposed as a solution for improving IoRL small-cells caching efficiency. IoRL is an emerging 5G small-cell for indoor environment, which utilises mmWave and Visible Light Communications (VLC) as access technologies, while exploiting Software Defined Networking (SDN) and Network Function Virtualisation (NFV) technologies to offer flexible and intelligent services to its clients. In this paper, we introduce MCaaS and IoRL-C services, we perform simulation work for testing IoRL-C as a proof of concept for both services. The network was simulated using OMNeT++ simulation tool, and we validated the services efficiency by comparing their performance with traditional deployments. We have also examined the cache service performance at different link lengths, and found out that IoRL-C is able to support IoRL small-cells with more than 50+Km separation distances.

媒体广播即服务：5G 室内 gNB 的行业融合机会和缓存服务

预计第五代 (5G) 移动网络将按照标准化委员会指定的严格性能目标执行。因此，建议对网络基础设施进行重大更改以达到预期的性能水平。网络功能虚拟化、云计算和软件定义网络是用于确保网络设计、最佳性能和高效资源利用的一些主要技术。上述技术正在将网络架构转变为基于服务而非基于设备的架构。在这方面，我们介绍了媒体广播即服务 (MCaaS) 和 IoRL-Cache 服务 (IoRL-C)。前者是作为广播业和移动网络运营商之间的集成解决方案提出的服务，而后者提出作为提高 IoRL 小基站缓存效率的解决方案。IoRL 是一种新兴的室内环境 5G 小基站，它利用毫米波和可见光通信 (VLC) 作为接入技术，同时利用软件定义网络 (SDN) 和网络功能虚拟化 (NFV) 技术为其提供灵活和智能的服务。客户。在本文中，我们介绍了 MCaaS 和 IoRL-C 服务，我们执行模拟工作来测试 IoRL-C，作为这两种服务的概念证明。网络使用OMNeT++模拟工具进行模拟，我们通过与传统部署的性能进行比较来验证服务效率。我们还检查了不同链路长度下的缓存服务性能，
