Introduction to ORAN
Open Radio Access Network(or ORAN) is a mobile phone network architecture where the core network and mobile stations are connected by means of an interface which is defined in a general way. Open Radio Access Network (ORN) is the core network of a mobile system. It is used to relay user information between base stations and mobile subscribers. Open Radio Access Networks (ORANs) are a class of wireless communication systems intended to support mobile and fixed use applications in which service providers share network infrastructure and allow user equipment (UE) owners to choose from a variety of network-specific policies. The ORAN is a personalized radio network that utilizes several forms of access, including hierarchical and interactive. The main difference between ORANs and traditional mobile networks is that the users have control over their personal data in an environment where the user is not required to be connected to a cellular base station at all times (i.e., anywhere from home or office), as opposed to today’s cellular systems. ORAN is the top-level architecture of an internetwork. Its main goal is to design a multivendor interoperable network, which could be built by any set of vendors. The network layer (IP) implements a set of protocol layers with the help of two parts: access technology and core protocols. In this article we describe the Open Radio Access network technology (ORAN) and its place relative to other radio access technologies. First we compare ORAN with traditional cellular networks, followed by an overview of traditional radio access technologies. We then present ORAN design elements and provide a high-level overview of its architecture using an illustrative example based on open source software. Open Radio Access Network is a series of devices with different functions that work together to provide the services needed by mobile-phone users. Open Radio Access Network (O-RAN) is radio access technology that provides all necessary features for mobile devices, such as handover and idle mode operation, to connect to the network. It is called an open network because it comprises both licensed and unlicensed spectrum.
In the Open Radio Access Network (Open RAN), the base stations are connected to the core network only over a backhaul. This means that all connectivity between the base station and other components of the mobile network (such as mobile switching centers) is handled over Layer 2 technology. In addition, there is no control plane in an Open RAN environment; all signaling for radio resources such as radio bearer setup and release happens through Layer 1 signaling standards like SPS. Open Radio Access Networks (ORAN) is a term used in a new technology area to mean the network infrastructure of radio nodes. Oran Open Radio Access Network (Oran) is a framework for deploying multi-access wireless access networks. This tutorial will step through the details of Oran and how it can be used to deploy Mesh Networks, including the B.A.I.N. project. ORAN (Open Radio Access Network) is an interoperable standard that provides users with a universal communication experience at the service level between operators, regardless of provider or technology. ORAN ensures interoperability in the core network and on the radio interface, enabling open access to global operator networks and their services.
