        Che-Chun Teng,Mei-Chun Chen,Min-Han Hung,Hong-Jie Chen 한국통신학회 2020 한국통신학회 APNOMS Vol.2020 No.09

        More and more telecom operators around the world began to build and to deploy fifth-generation (5G) mobile networks. With the advent of 5G service scenarios, it brings new challenges and increases the complexity of management. To deliver good quality of experience of these 5G applications for customers, service assurance is important. In this paper, we propose an end-to-end service assurance solution for 5G crosshaul networks. The 5G crosshaul network architecture consists of fronthaul, midhaul, and backhaul networks. Our solution deployed in 5G trial network in Chunghwa Telecom in Taiwan. The solution focus on slicing service assurance and synchronization monitoring. Besides, our solution adjusts most of network management in the operation support system (OSS) to apply to 5G crosshaul network. Our goal is to provide stable 5G transport network and to assure quality of experience for customers.
