碩士 === 國立交通大學 === 資訊科學與工程研究所 === 103 === 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.
