摘要: 本论文研制之基于数据分析的移动宽频4G LTE网路故障侦测,是研究并实现用于管理4G LTE行动宽频网路的系统。行动通讯网路故障,会对电信服务业造成一定的影响,甚至带来商业损失。目前的一些LTE网路管理系统,多数为仅针对网路中的部分设备进行局部的管理和控制,较少有系统或设备是用于管理整体网路的。而随着行动通讯网路的不断发展,用户所使用的客户端应用程式功能更丰富,对网路设备的传输能力之需求正不断的增加。对LTE网路进行综合监控,实时动态的了解网路资源分配情况,及时侦测网路故障,可以帮助网路管理者及时了解故障原因,准确定位故障位置,也可以进一步的使电信运营商了解用户对设备资源的需求,推进技术革新。
本论文议题之研究,是通过学习并研究,基于交通大学宽频行动通信实验室研究平台所提供的LTE宽频通讯网路,实现LTE网路故障侦测系统。结合传统网路管理系统技术和LTE通讯基站设备管理方法,综合观察数据传输过程中,从接入网,经过传输骨干网,到核心网路设备这一过程中,网路资源分配状况。实现对每个网路节点进行故障侦测。本次论文议题,通过实验观察分析,当LTE网路中出现因网路资源分配不均或出现资源抢占从而导致网路故障情形时,本议题所完成程式可判定故障节点位置和分析故障原因。
A system is defined to monitor and manage mobile broadband 4G LTE network. Network failure detection is the main function of this system. The network failures in mobile broadband network impact telecom services. It causes great loss to business. The current management systems used in the LTE network mostly deal with problems located in local domains. There are few systems used for monitoring the whole LTE network and evaluating network performance comprehensively. With the fast development of mobile broadband network and the increase of user requirements, the data transmission abilities and the capacities of network equipment are under great demand. Hence the comprehensive monitoring of LTE network is important to detect network failures and locate the fault node in a timely manner.
This thesis research is based on the LTE network environment supported by Mobile Broadband Laboratory (BML) of National Chiao Tung University (NCTU). We designed and realized a system for LTE network failure detection. The system integrates traditional network management technology with LTE system architecture. It takes the network resources allocation into consideration to detect failure caused by unbalanced resource allocation and resource preemption.
