Enabling Network Redundancy in the Radio Access Network

چکیده
The UTRAN consists of a set of Radio Network Subsystems connected to the Core Network through the Iu. The Iu interface has two flavours: the Iu-CS, connecting to the Circuit-Switched-domain, the Iu-PS when connecting to the Packet-Switched-domain. A Radio Network Subsystem (RNS) consists of a Radio Network Controller and one or more Node Bs. A Node B is connected to the RNC through the Iub interface. Inside the UTRAN, the RNCs of the Radio Network Subsystems can be interconnected together through the Iur. Iu, Iub and Iur are logical interfaces. Each RNS is responsible for the resources of its set of cells.

Access and Mobility Policy Control at the Network Edge
The fifth generation (5G) system architecture is defined as service-based and the core network functions are described as sets of services accessible through application programming interfaces (API). One of the components of 5G is Multi-access Edge Computing (MEC) which provides the open access to radio network functions through API. Using the mobile edge API third party analytics applications ...
متن کاملA Full-Duplex, Dual-Polarization 10Gbps Radio over Fiber system with wavelength reuse for upstream signal
This study presents a full-duplex Radio-over-Fiber (RoF) system providing the users' wireless access with a bit rate of 10 Gbps over 40 GHz radio carrier. This system can be used in a centralized radio access network (C-RAN) architecture because we provide a fully analog front haul link between central station and base station. We can consider it as infrastructure between remote radio heads (RR...

In this paper, we study WSN design, as a multi-objective optimization problem using GA technique. We study the effects of GA parameters including population size, selection and crossover method and mutation probability on the design. Choosing suitable parameters is a trade-off between different network criteria and characteristics. Type of deployment, effect of network size, radio communication...
