  • WorldCIST (2) - Radio Access Network Slicing in 5G
    Advances in Intelligent Systems and Computing, 2017
    Co-Authors: Jinjin Gong, Lu Ge, Xin Su, Jie Zeng
    Abstract:

    Network slicing is one of the key technologies for 5th-Generation (5G). It enables operators to construct Network slices with similar qualities as dedicated stand-alone Networks, but to realize them on a common physical platform. Meanwhile, the isolation among Logical Network slices can keep them from the negative impacts of other Network slices. In this paper, we give an overview of the radio access Network (RAN) slicing, and present some viewpoints on three categories of Network slices. Moreover, an approach, which dynamically creates RAN slice to meet specific business and service requirements, is proposed. It does not only optimize performance and maximize resources utilization, but also shorten the creating time of slices.

  • WTS - Orchestrating for deployment of Network slicing
    2017 Wireless Telecommunications Symposium (WTS), 2017
    Co-Authors: Changpeng Gu, Lu Ge, Jie Zeng, Xin Su, Chiyang XIAO
    Abstract:

    Network slicing has been proposed as an innovative concept to conduct a dedicated and customized Logical Network with virtualized and physical resources, which help operators to launch and customize service with more flexibility. We analyse the relationship between the Network slicing and physical Network and define a mathematical model to construct Logical Network function graphs that can be mapped to the physical Network. Further, we focus on demand oriented deployment of Network slicing applied to various application scenarios and formulate it as the integer quadratic programming for the placement of the Network functions and connecting them together considering the limited Network resources and QoS provision. We mainly discuss three kinds of Network slicing deployment policy that highly influence resource cost of physical Network. We evaluate resource utilization of Network slicing model using a small substrate Network scenario and analyze its deployment rule according to a combination of multiple optimization objectives and constraints implemented in YALMIP with CPLEX tools.

  • synthesis of intelligent control of traffic flows in urban roads based on the Logical Network operator method
    European Control Conference, 2013
    Co-Authors: Askhat I Diveev, E.a. Sofronova
    Abstract:

    A problem of optimal control of traffic flows in the urban Network is considered. A derivation of the mathematical model of control by the traffic lights at intersections is given. The mathematical model of control object is obtained using the controlled Networks theory. This model is a system of nonlinear finite-difference equations. To present a large scale road Networks the model contains the connection matrices. The connection matrices describe connections between input and output roads in subNetworks. These matrices allow considering the influence of traffic flows in one subNetwork the ones in other subNetwork. The traffic flow control is done by the coordination of active phases of traffic lights. The optimal control problem is to minimize the difference between the total input flow and total output flow for all subNetworks. To solve the optimal control synthesis problem we use a Logical Network operator method. An example of model for the Network of three subNetworks is given.

  • Cellular software defined Networking: A framework
    IEEE Communications Magazine, 2015
    Co-Authors: Abbas Bradai, Toufik Ahmed, Kamal Singh, Tinku Rasheed
    Abstract:

    Today's mobile customers desire to remain connected anywhere, at any time, and using any device. This phenomenon has encouraged mobile Network operators to build complex Network architectures by incorporating new features and extensions, which are harder to manage and operate. In this article we propose a novel and simplified architecture for mobile Networks. The proposed architecture, which we call CSDN (Cellular SDN), leverages software defined Networking (SDN) and Network functions virtualization (NFV). SDN abstracts the Network and separates the control plane from the data plane; NFV decouples Logical Network functions from the underlying hardware, for dynamic resource orchestration. Furthermore, we argue that dynamic resource orchestration and optimal control need real-time context data analyses to make intelligent decisions. Thus, in the proposed architecture we exploit the capability of the mobile edge Networks to gather information related to the Network as well as the users. This information can be used to optimize Network utilization and application performance, and to enhance the user experience. In addition, the gathered data can be shared with third party service providers, enabling the realization of innovative services.
