Enhanced mobile broadband (eMBB), ultra-reliable low latency communications (URLLC), and massive machine type communications (mMTC) demand a highly flexible and adaptive infrastructure. The traditional "one-size-fits-all" approach is no longer adequate for B5G services. This study evaluates the possible implementation of coexisting eMBB and URLLC services, analyzing how network slicing can effectively meet these demands, thereby emerging as a critical solution for B5G. Utilizing virtual private servers (VPS) and open-source software, specifically free5gc for the core network and UERANSIM for the radio access network and Kubernetes- based management and orchestration (MANO), the kube5gnfvo, two network slices are created within a single physical network. The paper presents two scenarios: one involving network slicing with two different user plane function (UPF), and another with distinct UPF and Session Management Function (SMF) for each slice. The results demonstrate the opensource ability in creation of network slicing in supporting diverse B5G service requirements. Keywords—eMBB, free5GC, free5gMANO, kube5gnfvo, Network Slicing, SMF, UERANSIM, UPF, URLLC. I. INTRODUCTION 5G represents the generation with the most significant changes in architecture and implementation modes compared to 4G. These advancements necessitate the support of advanced technologies and optimal solutions to meet the network requirements of IMT-2020 services. One of the key prominent concepts is network slicing, which enables the virtual division of a single physical infrastructure into multiple logical networks [1]. Each logical network is tailored to the specific needs of services such as eMBB, URLLC, and mMTC [2]. European Telecommunication Standard Institute (ETSI) network functions virtualization (NFV) - MANO plays a crucial role in the deployment of 5G network services (NSs). Each NS supports a network slice subnet as defined in 5G, and an end-to-end network slice is composed of multiple network slice subnets. Unlike physical network functions (PNFs), which have traditionally been deployed on proprietary hardware, MANO enables the deployment of virtual network functions (VNFs) on standard hardware. Notably, each network slice subnet or NS consists of one or more VNFs connected via virtual links (VLs), with their interactions depicted as VNF forwarding graphs (VNFFGs). Operators must deliver NSs with different QoS requirements, such as eMBB, URLLC, and mMTC [4]. ETSI NFV MANO interaction with operation/business support system (OSS/BSS). The OSS/BSS comprises two functionalities, the network slice management function (NSMF) and network slice subnet management function (NSSMF). The NSMF provides management services of for network slice instances (NSIs) while NSSMF is responsible for management of network slice subnet instances (NSSIs). An NSI could consist of multiple NSSIs and an NSSI could consist of multiple VNFs. The interaction between OSS/BSS and ETSI NFV MANO can be seen as MANO is responsible with the dynamic oversight of network slices and the associated VNFs. This involves the real-time initiation, termination, and monitoring of these components to facilitate scaling automatic healing. While the traditional OSS/BSS is responsible for the role on static management tasks including provisioning and deprovisioning of network slices. The element management system (EMS) functions as the network function management function (NFMF), delivering management services for PNFs. In addition, to effectively manage VNFs, the NFMF engages with the virtual network function manager (VNFM) via the Ve-Vnfm-em interface. At a higher hierarchical level, the NSSMF communicates with the NFV orchestrator (NFVO) through the Os-Ma-NFVO interface. The NSSMF and NFMF collaboratively interact with MANO framework to execute the fault, configuration, accounting, performance, and security (FCAPS) network management functions as defined by the International Organization for Standardization (ISO) [5]. The objective of this paper is to develop a 5G mobile communication system utilizing open-source software, enabling users to swiftly deploy 5G network slices.
