摘要/Abstract

摘要： 针对各种智能设备在移动蜂窝网络中的普及及移动流量需求日益增长的问题，研究控制无线电带宽并将其分配给多个无线电用户设备，提出了一个基于软件定义网络（SDN）的资源分配框架，以及LTE/WLAN多无线电网络中异构资源分配算法。该框架将SDN范式应用到LTE-WLAN集成网络的异构资源分配，并进行了扩展，以整体的方式分配LTE/WLAN多无线电网络中的异构射频带宽。通过将集中式解决方案的功能分解到指定的网络实体的方式，来处理异构资源。模拟实验表明，所提框架可以较好地平衡网络吞吐量和用户公平性，且算法收敛性较好。

Abstract: For the popularity of various smart devices in mobile cellular network, and the problem of increasing mobile traffic, the control of radio bandwidth was studied and the radio bandwidth was assigned to multiple radio user equipments. A resource allocation framework based on Software Defined Network (SDN), and a heterogeneous resource allocation algorithm in the LTE/WLAN (Long Term Evolution/Wireless Local Area Network) radio network were proposed. The SDN framework was applied to the heterogeneous resource allocation of LTE-WLAN integrated network, and the framework was extended, and the heterogeneous radio frequency bandwidth in the LTE/WLAN multiple radio network was allocated in a holistic way. Heterogeneous resources could be processed by decomposing the function of centralized solutions to the designated network entities. Simulation experiments show that the proposed framework can better balance network throughput and user fairness, and the algorithm has better convergence.

Key words: mobile cellular network, heterogeneous resource, Software Defined Networking (SDN), bandwidth, resource allocation
