Overview of Network Outage Detection Technology in 5G

Understanding the network outage is beneficial to improve and enhance the security of the network. Detecting the outage can easily locate the event source and estimate the spread of the outage. Large-scale network outages will seriously affect the normal operation of network services and infrastructure. This study summarizes and compares the existing methods of network outage detection, and looks forward to future research on network interruptions, to provide a reference for the subsequent research on network security in 5G.
