This paper describes the experimentation on the Future Internet Research & Experimentation (FIRE) Long Term Evolution (LTE) testbeds for open experimentation (FLEX) facilities by combining the existing Evolved Node B (eNB) with an execution infrastructure. In this direction, LTE Edge Network Enhancement with Core Functionalities (LENA) project will enhance the LTE FLEX testbed with a Network Function...
Software-Defined Networking (SDN) paradigm provides many features including hardware abstraction, programmable networking and centralized policy control to networks. In the next generation mobile networks, one of the main benefits that can be used along with these features is core/backhaul SDN-based network virtualization. In this article, we propose a novel shared SDN-based Evolved Packet System...
Radio Access Network (RAN) sharing and Cloud-RAN (C-RAN) are two major candidates for next generation mobile networks. RAN sharing ensures efficient usage of network equipments among multiple mobile network operators (MNOs) and C-RAN benefits installation, evolution, management and performance improvements. Similarly, Software-Defined Networking (SDN) concept provides many features including hardware...
In this paper, we propose a novel cellular network architecture including network virtualization controller for mobile core and backhaul sharing. Software-Defined Networking (SDN) based network virtualization is applied into Evolved Packet System (EPS) architecture of Long Term Evolution (LTE) networks. After virtualization of all evolved Node-Bs (eNodeBs) associated with different Mobile Operators...
Mobile Network Virtualization (NV) is an emerging technique where multiple mobile network providers can share the infrastructure and the physical resources with each other, which leads to the improvement of system performance and the reduce of overall costs. In this paper, we propose a framework for inter-operator resource sharing through base station (BS) virtualization in Long Term Evolution (LTE)...
The continuous growth in using mobile devices (e.g. smart phones, tablets, etc.) has increased the complexity in provisioning cellular network resources. Applying the cloud computing model in LTE (Long Term Evolution) systems could be a good solution to increase LTE's performance by building a shared distributed mobile network that can optimize the utilization of resources, minimize communication...
The 4G Evolved Packet Core (EPC) is the pillar of the Long Term Evolution (LTE) mobile networks. Inspired by the current trend of designing distributed and more autonomous systems, we can notice that the complexity of the existing EPC seriously limits this possibility. We principally consider a reshaping of cellular networks in order to move towards virtual-distributed architectures allowing dynamic...
