Abstract:

  • 5G iRAN tries to build an intelligent RAN solution for 5GS and various QoS demands, such as low latency, high reliability, survival time. This will integrate 5G wireless communications with the function module in factory. 5G iRAN will be developed according to 3GPP IIoT/NPN and O-RAN RIC based on III 5G gNB/5GC solution. At least three scenario demonstrations of future factory would be developed and verified in this project. The goal is to provide the 5GS E2E solution, QoS-aware wireless private network for the smart factories in 5G era.
  • In the modern factories, all types of machines, tools, and sub-systems have to be connected to each other for data exchange or sharing. Thus the communication middleware is quite critical to the IIoT functions and applications. ROS2 is based on the DDS decentralized/non-synchronous data exchange mechanism with high QoS control capability. With this feature, it is very suitable for building the communication and intelligent control between robot arm, AGV and AR glasses in the factory. It can also expand to the application as a transmission standard for factory networks. It is conducive make the future factory more easily to deploy but the intelligent control for ICT systems.

Abstract: The free5GC is an open-source project for 5th generation (5G) mobile core network led by researchers from National Chiao Tung University. The free5GC is the first open-source core network in the world based on the 3GPP Release 15 (R15) specifications. The ultimate goal of free5GC is to implement a full commercially operational core network including Operation, Administration and Management (OAM), orchestrator, and network slicing complied with 3GPP R15 and beyond. In the past, the cellular core network was very expensive and not easy to access the source code. For people doing research in cellular core networks, they usually could only conduct mathematical analysis and simulation to verify their ideas. With free5GC, researchers not only can get the source code for free, but also can realize their own ideas in a real 5G core network environment. The free5GC can facilitate innovations in prototype and testbed development.

Abstract: 5G network is expected to cater the varied requirements and business needs of verticals. The key challenge for more complex and flexible 5G network results from the scale and flexibility of deployment, optimization, management, and orchestration of the network. O-RAN Alliance is a world-wide community of over 200 members and aims to transform the RAN towards to open, intelligent, virtualized, and fully interoperable. A flexible and customer-oriented network for verticals can be achieved by the merits of openness, intelligence, and virtualization. Moreover, network with intelligence especially tackles the difficulties of manual management and complicated network parameter optimization to better user experience. Considering the diversified QoE demand can’t be satisfied by current QoS framework, an intelligent UE-centric service network is showcased to improve the user experience which takes into account radio conditions, priority of users, and video requirements. Main features include

  • RAN Intelligent Controller prototype which enables network planning as well as dynamic network optimization to improve network coverage and capacity for moving UE

Industry Demo 6 (Live): Towards 5G Cloud-Native: Automation and Flexible Network Aggregation

Abstract:
Auto-scaling, frequent deployment of services with a quick failure recovery (e.g., service availability > 99.999 %) are essential features to support 5G and beyond networks in cloud environments. Such service resiliency, flexibility and network automation in 5G networks as required for network slicing and orchestration, as well as services' evolution (e.g., service update/upgrade, scaling etc.), can be achieved via softwarization, virtualization, and cloud computing technologies. Aiming at delivering the applications as-as-service, cloud-native is a methodology of developing, building, and managing the applications that fully exploit the cloud computing model. Agility, self-healing and auto-pilot (e.g., auto-configuration), among others, are considered as the core features envisioned for 5G in cloud native environment.

There are three main design patterns for cloud-native approach. Firstly, the cloud-native applications are composed of microservices, where they can be composed of many services meshed together and operating independently of each other. Secondly, the cloud-native applications are packaged in one or multiple isolated containers, while managed by means of a set of standard APIs. Finally, they run in a continuous integration and delivery (CI/CD), where an application goes through fast cycles of development, build, test, release, and deployment.

Considered as one of the main features attracting the adoption 5G and beyond in cloud native environment, microservices and containers have small footprint and fast start times. There are many technologies for containerization, such as Linux Containers (LXC), containerd, CRI-O, docker, with a relatively similar performance. In order to cloudify the network, flexible functional split was introduced by 3GPP [TR 38.801] to cope with the ever increasing COPEX/CAPEX with the introduction of new services in 5G. Contrary to monolithic 4G RAN, 5G RAN is disaggregated into three main units: the Remote Radio Unit (RRU), the Distributed Unit (DU), and the Centralized Unit (CU). All the necessary components related to signal transmission/reception exist in RRU, while DU may contain a set of physical layer functions shifted to the cloud as well as some set of higher layer functions. The rest of higher layer functions will be then treated/processed at the CU. Similarly, the core network can be, monolithic (running as singly entity), disaggregated, or even re-aggregated for different objectives like optimize the resources, reduce the traffic on /access/mid/back-haul, etc. After shifting 5G functions to the cloud (i.e., build them as a cloud-native applications), the number of containers may grow drastically on per service basis (i.e., network slices and sub-slices). This calls for efficient management and orchestration of the ecosystem in order to achieve the envisioned performance. Several frameworks already exist, such as Kubernetes, Docker Swarm, and Apache Mesos. For the ease of packaging, deploying and managing Kubernetes applications, Operator framework is introduced under Kubernetes environment for encapsulating the lifecycle management operations, and thus facilitating service automation. Kue5G-Operator is a good example of such Kubernetes Operator, which will be exploited in this demo. It is worth noting that Kubernetes is considered as a defacto candidate for the orchestration of 5G and beyond in cloud environment as it has the largest community, better support, and thus long term support. The same also holds for Docker container model.

Motivated by the necessity of quick 4G/5G service deployed, re-configuration, and dynamic network management according to the ongoing user traffic, we present the current demo. In this demo, we present 5G dynamic network deployment, (dis/re-) aggregation, and (re)configuration in cloud-native environment. More specifically, we demonstrate in this demo the following: i) support 5G in cloud native via Kube5G-Operator and dynamically automate the network, i.e. upgrade/downgrade services, ii) change the configuration automatically, iii) dynamically switch between (dis/re-)aggregation modes for both CN and RAN according to user traffic. Note that the aforementioned features of Kube5G- Operator spans different phases of openshift operator, ranging from basic install (e.g., application provision), to auto-pilot (e.g., auto-configuration).

Industry Demo 7 (Live): IS-Wireless RAN Controller for managing the SD-RAN networks

Date/Time: 10 December 2020, Thursday: 16:00-17:30
Room: 201F

Abstract: As per 3GPP standards, 5G RAN is a logical architecture that can be implemented and deployed in different ways depending on operator requirement and preferences, therefore 5G becomes more ‘Network of functions’ rather than a ‘Network of entities.’ Moreover with the availability of 5G specifications (e.g. CUPS, functional split concept), omnipresent virtualization platforms, and the introduction of Software Defined Network (SDN) concept into the mobile infrastructure (RAN virtualization) it will become possible to combine the capabilities together in order to enable configuration, optimization and control of the underlying RAN infrastructure from centralized location called RAN Controller (or aggregation points). Therefore, it is possible to expose eNB/gNB functionalities as xApps (i.e. applications such as Admission control, Radio optimization, Mobility management or any other 3rd party xApps) that are available as plug-ins for the RAN Controller to enforce policies via southbound (SB) interface towards the radio stack. Such an architecture provides such an unprecedented approach for controlling radio resources.

Building on the principles of softwarization, virtualization programmability and intelligence, there has been a huge global interest from the operators towards enhancing the existing RAN architecture. The objective is to assure Software-Defined RAN architecture that provides an efficient radio connection and management control for current and beyond fifth generation (5G) networks.

The focus of the proposed demonstration is the proprietary RAN controller in an interactive environment with SD-RAN, both developed by IS-Wireless. The purpose of this demo is to show the complete interaction of the network administrator with the RAN network that is managed by the network management dashboard backed up by the xApps. The objective will be to first define authorized users who can enter the network in combination with suitable admission control settings (via xApp), perform a sample network provisioning and configuration. The administrator console will be presented that allows configuring the xApps (admission control, simple RRM algorithm) together with a dashboard for performance monitoring visualizations relevant to the scenario (e.g. UE rejection/Acceptance, PRBs, throughput). In addition, the flexible resource allocation policy will be provided with the user interface, allowing custom PRB management (GBR, RR). The RRM settings would in turn be enforced down to the mobile network substrate. We will show that there is online exchange of information between the administrator RAN Controller SD-RAN and the UEs. We will also show how xApps running inside the RAN controller interacts via SB interface with the stack. The number of UEs and their type of connection with the eNB will depend on the capabilities at the venue (i.e. whether we rely on the radio spectrum or cable between eNB and the UE). All in all this event will demonstrate capabilities of ISW’s RAN controller managing resources of an underlying SD-RAN.

  1. Admission Control xApp: Application that includes basic criteria to admit or reject users and control the execution of eNB/gNB in such a way that requested QoS can be achieved for the UE seeking admission.
  2. Scheduling xApp: Legacy scheduling algorithm (e.g. RR, PF) deployed as xApp to allocate a number of RBs but also a custom scheduler will be presented to successfully operate with RAN controller.
  3. Graphical User Interface (GUI): A dedicated graphical user interface will be used to manage the ORAN based SD-RAN deployment (RAN configuration) and provide immediate and visual measures about the effect of each execution (sample KPIs collection).
